Description

筐体及び通信装置Housing and communication device
 本発明は、筐体および通信装置に関する。 The present invention relates to a housing and a communication device.
 非接触で人の手を介さず対象物を自動的に認識する、「自動認識技術(Automatic Identification and Data Capture;以下、AIDCと略す)」が利用されつつある。AIDCでは、図1に示すように対象物に付与されたICタグ3(Integrated Circuit Tag)と、ICタグ3の情報を読み出したり書き換えたりするリーダライタ5とを使用する。ICタグ3はアンテナ7とICチップ9とを備える。 “Automatic identification and data capture (hereinafter abbreviated as AIDC)”, which automatically recognizes an object without contact with a human hand, is being used. In the AIDC, as shown in FIG. 1, an IC tag 3 (Integrated Circuit Tag) attached to an object and a reader / writer 5 that reads and rewrites information of the IC tag 3 are used. The IC tag 3 includes an antenna 7 and an IC chip 9.
 AIDCの動作は一般的に以下の通りである。まずリーダライタ5から情報を載せた電波や電磁波を送信し、ICタグ3中のアンテナ7が受信する。続いて、アンテナ7で受信した情報を載せた電波等を電気信号79に変換する。その後、情報を載せた電気信号79をICチップ9に送り、その結果の情報を得た電気信号(以下、返答電気信号97という)をアンテナ7に戻す。この返答電気信号97をアンテナ7において電波等に変換し、リーダライタ5に返答電波等75を戻す。これらの動作によりリーダライタ5とICタグ3との間で情報のやり取りがなされる。このAIDCは、例えば物流において多量の貨物を目的地別に自動的に振り分けるといった個体管理において広く活用され、他に物品などの履歴管理や個人認証などにも活用されつつある。 The operation of AIDC is generally as follows. First, a radio wave or electromagnetic wave carrying information is transmitted from the reader / writer 5, and the antenna 7 in the IC tag 3 receives it. Subsequently, a radio wave or the like carrying information received by the antenna 7 is converted into an electric signal 79. Thereafter, an electric signal 79 carrying information is sent to the IC chip 9, and an electric signal obtained as a result of the information (hereinafter referred to as a reply electric signal 97) is returned to the antenna 7. The response electric signal 97 is converted into a radio wave or the like at the antenna 7, and the response radio wave or the like 75 is returned to the reader / writer 5. With these operations, information is exchanged between the reader / writer 5 and the IC tag 3. The AIDC is widely used in individual management such as automatically distributing a large amount of cargo according to destination in logistics, and is also being used for history management of items and personal authentication.
 AIDCに使用されるICタグは、動作電源の観点から大きく、アクティブ方式とパッシブ方式との2種類に分類される。アクティブ方式のICタグは電池を内蔵し、この電池により動作する。そのため長距離通信に適しているが、電池の交換を要するなどのデメリットを有する。一方、パッシブ方式のICタグは、電池を内蔵せず、リーダライタからの電波を用いてICタグ内で起電し、これにより動作する。
 一般的にパッシブ方式のICタグは、アクティブ方式に比べ、小型化、軽量化でき、安価であるため、長距離通信を必要としない用途において広く使用されている。
IC tags used for AIDC are large from the viewpoint of operating power supply, and are classified into two types, an active method and a passive method. An active IC tag has a built-in battery and operates with this battery. Therefore, it is suitable for long-distance communication, but has a demerit such as requiring battery replacement. On the other hand, a passive IC tag does not contain a battery, operates in the IC tag using radio waves from a reader / writer, and operates accordingly.
Generally, passive IC tags are widely used in applications that do not require long-distance communication because they can be reduced in size and weight and are less expensive than active IC tags.
 AIDCに使用されるICタグは、使用する電波等の観点から、電磁誘導方式と電波方式との2種類に分類される。やり取り可能な通信距離、データ送信スピード、無線LAN等との干渉の観点から、電磁誘導方式ではHF帯(High Frequency、短波帯、13.56MHz)が、電波方式ではUHF帯(Ultra High Frequency、極短波帯、860~960MHz)が使用されている。 IC tags used for AIDC are classified into two types, electromagnetic induction and radio wave systems, from the viewpoint of radio waves used. From the viewpoint of communication distance that can be exchanged, data transmission speed, interference with wireless LAN, etc., the electromagnetic induction method uses the HF band (High Frequency, short wave band, 13.56 MHz), and the radio wave method uses the UHF band (Ultra High Frequency, pole A short wave band, 860 to 960 MHz) is used.
 近年では、ICタグは物流などだけでなく、多量のサンプル管理等を容易に実現できる観点から科学技術分野、特に医療分野等での使用が検討されつつある。
 科学技術分野では、多量のサンプルの入った試料瓶をオートサンプラーなどにより、自動で測定や計測を実施している。作業者は予め個々のサンプルの情報や管理番号を把握しておき、オートサンプラーの所定の位置にセットし、測定等を行う。測定等実施後に結果を得、予め把握していたサンプルの情報と結果とを作業者が照合し解析等を実施する。この際に、サンプルの情報と結果との照合においてミスが発生し再度測定することがあった。さらに医療分野では、サンプルの情報と結果との照合ミスで誤診断に繋がるといった課題があった。
In recent years, the use of IC tags not only in logistics but also in science and technology, particularly in the medical field, is being considered from the viewpoint of easily realizing a large amount of sample management.
In the science and technology field, sample bottles containing a large amount of sample are automatically measured and measured using an autosampler. The operator grasps the information and management number of each sample in advance, sets it at a predetermined position of the autosampler, and performs measurement. The result is obtained after the measurement and the like are performed, and the operator collates the information and the result of the sample that has been grasped in advance, and performs the analysis or the like. At this time, an error occurred in the comparison between the sample information and the result, and measurement was sometimes performed again. Further, in the medical field, there has been a problem that a mistake in collation between sample information and results leads to a misdiagnosis.
 また医療分野では、測定の正確性を向上するために、使用する試料瓶については使いまわさずに、容易に廃棄可能な材質としてプラスチックが使用されつつある。
 上記の課題を解決するために、容易に廃棄可能で安価な試料瓶として、ICタグを付与したプラスチック製試料瓶が考えられている(例えば、特許文献1)。
In the medical field, in order to improve the accuracy of measurement, plastic is being used as a material that can be easily discarded without using the sample bottle used.
In order to solve the above problems, a plastic sample bottle provided with an IC tag is considered as an inexpensive sample bottle that can be easily discarded (for example, Patent Document 1).
日本国特許第5052079号公報Japanese Patent No. 5052079
 ICタグを付与したプラスチック製試料瓶は、例えばICタグをプラスチック製試料瓶のプラスチック中に内包することとなる。しかしながら、情報のやり取りや起電のための電波等が、プラスチック中の水分による干渉や減衰でICタグに到達しにくくなる。一般的なプラスチック容器の比誘電率が10以下であるのに対し、水は比誘電率が80と大きいため、電波等をプラスチック容器に透過させようとすると、水分子の振動等により、電波等と干渉する。以上のことからデータ送信の長時間化、通信エラーなどの課題があった。 For example, a plastic sample bottle to which an IC tag is attached encloses the IC tag in the plastic of the plastic sample bottle. However, radio waves for information exchange and electromotive force are difficult to reach the IC tag due to interference and attenuation due to moisture in the plastic. While the relative permittivity of a general plastic container is 10 or less, water has a large relative permittivity of 80. Therefore, when radio waves or the like are transmitted through the plastic container, radio waves or the like are generated due to vibrations of water molecules. Interfere with. From the above, there are problems such as long data transmission and communication errors.
 本発明は、前述した課題に鑑みてなされたものであり、その目的は、情報のやり取りや起電のための電波等に干渉せず、電波等を減衰させにくい筐体および通信装置を提供することにある。 The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a housing and a communication device that do not interfere with radio waves or the like for information exchange or electromotive force and do not easily attenuate radio waves or the like. There is.

 以下、本発明の実施形態について説明するが、本発明は以下の実施形態に限定されない。また、本発明の範囲を逸脱することなく、以下の実施形態に種々の変形及び置換等を加えられる。 Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the following embodiments. Various modifications and substitutions can be made to the following embodiments without departing from the scope of the present invention.
 (筐体用透明基材)
 本発明における筐体用透明基材(以下、単に透明基材と称することがある。)は、含水量が1質量%以下の部材からなる。本発明の筐体用透明基材を使用すると、電波等の減衰等の原因となる水分が透明基材中に少ないため、情報のやり取りや起電のための電波等が、透明基材中の水分により干渉や減衰を受けにくくなる。これにより、電波等がICタグに到達しやすくなり、データ送信の短時間化やエラーの抑制が可能である。含水量は0.5質量%以下が好ましく、0.2質量%以下がより好ましく、0.1質量%以下がさらに好ましい。
(Transparent substrate for housing)
The transparent substrate for housing in the present invention (hereinafter sometimes simply referred to as a transparent substrate) is composed of a member having a water content of 1% by mass or less. When the transparent base material for a casing of the present invention is used, there is little moisture in the transparent base material that causes attenuation of radio waves and the like. Less susceptible to interference and attenuation by moisture. As a result, radio waves and the like can easily reach the IC tag, and data transmission can be shortened and errors can be suppressed. The water content is preferably 0.5% by mass or less, more preferably 0.2% by mass or less, and further preferably 0.1% by mass or less.
 本発明の筐体用透明基材の含水量の下限値は特に制限はないが、含水量は0.002質量%以上が好ましい。0.01質量%以上がより好ましく、0.015質量%以上がさらに好ましい。 The lower limit of the moisture content of the transparent base material for a casing of the present invention is not particularly limited, but the moisture content is preferably 0.002% by mass or more. 0.01 mass% or more is more preferable, and 0.015 mass% or more is further more preferable.
 ここで、「筐体」とは物品を納められる箱を示し、本発明の筐体用透明基材を使用して作製された箱である。平板状の筐体用透明基材に他の部材を組み合わせて筐体を形成してもよく、筐体用透明基材を例えば成形プロセスにより屈曲部を付与して筐体を形成してもよい。
 なお、本願発明の筐体は後述の通り、電波授受用アンテナも備える。
Here, the “casing” refers to a box in which an article can be stored, and is a box manufactured using the transparent substrate for casing of the present invention. The casing may be formed by combining other members with the flat transparent substrate for casing, or the casing may be formed by adding a bent portion to the transparent substrate for casing by, for example, a molding process. .
In addition, the housing | casing of this invention is also equipped with the antenna for electromagnetic wave transmission / reception as mentioned later.
 筐体用透明基材の材質は、上記含水量を満たせば特に限定されないが、例えばポリカーボネート、アクリル、ポリエチレン、ポリプロピレン、ポリスチレン、ポリ塩化ビニル、ポリエステル樹脂等の樹脂から適宜選択して用いることが好ましい。これは安価で使い捨てしやすく、生物学的有害物などを簡易に廃棄できるためである。樹脂では、成形加工性や耐薬品性の観点から、ポリプロピレンやポリエチレンがより好ましい。 The material of the transparent substrate for housing is not particularly limited as long as the water content is satisfied. For example, it is preferable to select and use suitably from resins such as polycarbonate, acrylic, polyethylene, polypropylene, polystyrene, polyvinyl chloride, and polyester resin. . This is because it is inexpensive and easy to dispose of and can easily dispose of biological harmful substances. As the resin, polypropylene and polyethylene are more preferable from the viewpoint of moldability and chemical resistance.
 ここで、筐体用透明基材に樹脂を使用した場合、含水量を求めたい樹脂を水分気化装置内において150℃で加熱し、蒸発させた水分をカールフィッシャー試薬に導く。この試薬をJIS K0113(2005)に従って容量滴定法により含水量を見積もれる。 Here, when a resin is used for the transparent base material for the casing, the resin whose water content is to be obtained is heated at 150 ° C. in the moisture vaporizer, and the evaporated moisture is led to the Karl Fischer reagent. The water content of this reagent can be estimated by volumetric titration in accordance with JIS K0113 (2005).
 筐体用透明基材の厚さ1mmにおける波長600nmの光の直線透過率は、50%以上が好ましい。筐体用透明基材を用いた筐体に測定光を透過させて光学測定等を実施する場合、測定光を透明基材が吸収し、信頼性の高い測定を実施できなくなる。そこで、光の直線透過率を下限値以上とすることで、測定光が筐体により干渉されにくくなり、信頼性の高い測定ができるようになる。光の直線透過率は、60%以上がより好ましく、70%以上がさらに好ましい。 The linear transmittance of light having a wavelength of 600 nm at a thickness of 1 mm of the transparent substrate for housing is preferably 50% or more. When optical measurement or the like is performed by allowing measurement light to pass through a housing using the transparent base material for the housing, the transparent base material absorbs the measurement light, making it impossible to perform highly reliable measurement. Therefore, by setting the linear transmittance of light to be equal to or higher than the lower limit value, the measurement light is less likely to be interfered by the housing, and a highly reliable measurement can be performed. The linear light transmittance is more preferably 60% or more, and further preferably 70% or more.
 (筐体2)
 図2(a)に示すように、本発明に係る筐体2は、電波授受用アンテナ7と、含水量が1質量%以下の筐体用透明基材4と、を備える。筐体2は第1主面4aと第2主面4bとを有する。さらに、筐体2は第1主面4aを基準面とし、基準面から第2主面4b側に、電波授受用アンテナ7を備える。
 本発明の筐体2では、情報のやり取りや起電のための電波等が透明基材4による干渉や減衰を受けにくくなる。このため、電波等がICタグ3に到達しやすくなり、データ送信の短時間化やエラーの抑制が可能である。
(Case 2)
As shown in FIG. 2A, the housing 2 according to the present invention includes a radio wave transmitting / receiving antenna 7 and a housing transparent substrate 4 having a water content of 1% by mass or less. The housing 2 has a first main surface 4a and a second main surface 4b. Further, the housing 2 includes a first principal surface 4a as a reference surface, and a radio wave transmitting / receiving antenna 7 on the second principal surface 4b side from the reference surface.
In the case 2 of the present invention, radio waves and the like for information exchange and electromotive force are less susceptible to interference and attenuation by the transparent substrate 4. For this reason, radio waves or the like can easily reach the IC tag 3, and data transmission can be shortened and errors can be suppressed.
 本発明の筐体2は、図2(b)に示すように、第1主面4aが、作業者が接触可能な面であることが好ましい。電波授受用アンテナ7が作業者の触れられる第1主面4aから第2主面4b側にあるため、電波授受用アンテナ7が第1主面4aから出っ張らない。また電波授受用アンテナ7と第1主面4aとを面一とできる。これにより電波授受用アンテナ7が損傷を受けにくくなるため、繰り返し使用でもデータ送信の精度向上を実現できる。 As for the housing | casing 2 of this invention, as shown in FIG.2 (b), it is preferable that the 1st main surface 4a is a surface which an operator can contact. Since the radio wave transmitting / receiving antenna 7 is located on the second main surface 4b side from the first main surface 4a touched by the operator, the radio wave transmitting / receiving antenna 7 does not protrude from the first main surface 4a. Further, the radio wave transmitting / receiving antenna 7 and the first main surface 4a can be flush with each other. As a result, the radio wave transmission / reception antenna 7 is less likely to be damaged, so that the accuracy of data transmission can be improved even after repeated use.
 電波授受用アンテナ7は、図2(c)に示すように、第1主面4aの基準面より第2主面4b側にあることがより好ましい。電波授受用アンテナ7は筐体2を構成する透明基材4などに覆われるなどにより、作業者が電波授受用アンテナ7にさらに触れにくくなり損傷を受けにくくなる。このため、繰り返し使用でもデータ送信の精度向上を実現できる。また、電波授受用アンテナ7の存在箇所に取り外し可能な蓋を設けてもよい。これにより測定機器で使用する電波に応じて電波授受用アンテナ7を交換できる。また、医療分野などに使用した場合、汚染されたサンプル容器を廃棄する際に、容易にかつ安全に電波授受用アンテナ7やICタグ3を回収できる。
 なお、電波授受用アンテナ7は、図2(a)~(c)に示すような筐体2の側面に設置することに限られず、筐体2の底部に設置してもよく特に制限はない。
As shown in FIG. 2C, the radio wave transmitting / receiving antenna 7 is more preferably located closer to the second main surface 4b than the reference surface of the first main surface 4a. The radio wave transmission / reception antenna 7 is covered with the transparent base material 4 or the like constituting the housing 2, so that the operator is less likely to touch the radio wave transmission / reception antenna 7 and is not easily damaged. For this reason, the accuracy of data transmission can be improved even by repeated use. Further, a removable lid may be provided at a location where the radio wave transmitting / receiving antenna 7 is present. As a result, the radio wave transmitting / receiving antenna 7 can be exchanged according to the radio wave used in the measuring instrument. Further, when used in the medical field, the radio wave transmitting / receiving antenna 7 and the IC tag 3 can be easily and safely collected when the contaminated sample container is discarded.
The radio wave transmission / reception antenna 7 is not limited to being installed on the side surface of the housing 2 as shown in FIGS. 2A to 2C, and may be installed on the bottom of the housing 2 without any particular limitation. .
 本発明の筐体2は、電波授受用アンテナ7がICタグ3を構成することが好ましい。ICタグ3は、電波授受用アンテナ7とICチップ9とを備え、パッケージ化された小型装置である。ICタグ3は一般的にパッケージ化されており、-40℃以上150℃以下の処理でも破損しにくく、例えば、滅菌処理の条件にも耐えられる。また、本発明の筐体2が試料瓶である場合でも、小型のICタグ3であれば組み込める。 In the case 2 of the present invention, the radio wave transmitting / receiving antenna 7 preferably constitutes the IC tag 3. The IC tag 3 is a small device that includes a radio wave transmitting / receiving antenna 7 and an IC chip 9 and is packaged. The IC tag 3 is generally packaged, and is not easily damaged even in a process of −40 ° C. or higher and 150 ° C. or lower, and can withstand, for example, sterilization conditions. Even when the housing 2 of the present invention is a sample bottle, it can be incorporated if it is a small IC tag 3.
 本発明の筐体2は、電波授受用アンテナ7が、データ読取書換に使用する電波を受信することが好ましい。図1のように、筐体2から離間して設置された測定装置などに組み込まれたリーダライタ5から情報を載せた電波等を送信し、筐体中の電波授受用アンテナ7が受信する。続いて、受信した情報を載せた電波等を電波授受用アンテナ7において電気信号に変換する。その後、例えばICタグ3内であれば、情報を載せた電気信号79をICチップ9に送り、その結果の情報を得た電気信号(以下、返答電気信号97という)を電波授受用アンテナ7に戻す。この返答電気信号97を電波授受用アンテナ7において電波等に変換し、リーダライタ5に返答電波等75を戻す。これらの動作によりリーダライタ5とICタグ3との間で情報のやり取りがなされ、測定装置と筐体2との情報を同期できる。これによりサンプルの情報と測定結果との関連性が明確化され、作業効率が向上できると共に、誤作業を低減できるようになる。 In the case 2 of the present invention, the radio wave transmission / reception antenna 7 preferably receives radio waves used for data reading and rewriting.

 NiOの含有量は酸化物基準のモル%表示で0.3%以下が好ましい。NiOは、製造装置から容易に混入しやすいだけでなく、少量の混入でもガラスを着色しやすい。NiOの混入は、電波等を減衰させやすいだけでなく、筐体用ガラスを用いたガラス筐体に測定光を透過させて光学測定等を実施する場合、測定光をガラスが吸収し、信頼性の高い測定を実施できなくなる。そこで、NiOの含有量を上限以下とすることで、情報のやり取りや起電のための電波等がガラスによる干渉や減衰をより受けにくくなる。このため、電波等がICタグに到達しやすくなり、データ送信の短時間化やエラーの抑制が可能である。さらに、光学測定の場合、筐体のNiOの含有量を上限以下とすることで、測定光がガラス筐体により干渉されにくくなり、信頼性の高い測定ができるようになる。

The content of NiO is preferably 0.3% or less in terms of mol% based on oxide. NiO is not only easily mixed from a manufacturing apparatus, but also glass is easily colored with a small amount. Mixing of NiO not only tends to attenuate radio waves, but also when measuring light is transmitted through a glass housing using glass for housing to perform optical measurements, the measurement light is absorbed by the glass and reliability is improved. High measurement cannot be performed. Therefore, by setting the content of NiO to the upper limit or less, radio waves for information exchange and electromotive force are less susceptible to interference and attenuation by glass. For this reason, radio waves or the like easily reach the IC tag, and data transmission can be shortened and errors can be suppressed. Further, in the case of optical measurement, by setting the content of NiO in the housing to the upper limit or less, the measurement light is not easily interfered by the glass housing, so that highly reliable measurement can be performed.

 Crの含有量は酸化物基準のモル%表示で0.3%以下が好ましい。Crは、製造装置から容易に混入しやすいだけでなく、少量の混入でもガラスを着色しやすい。Crの混入は、電波等を減衰させやすいだけでなく、筐体用ガラスを用いたガラス筐体に測定光を透過させて光学測定等を実施する場合、測定光をガラスが吸収し、信頼性の高い測定を実施できなくなる。そこで、Crの含有量を上限以下とすることで、情報のやり取りや起電のための電波等がガラスによる干渉や減衰をより受けにくくなる。このため、電波等がICタグに到達しやすくなり、データ送信の短時間化やエラーの抑制が可能である。さらに、光学測定の場合、筐体のCrの含有量を上限以下とすることで、測定光がガラス筐体により干渉されにくくなり、信頼性の高い測定ができるようになる。
 Crの下限値は特に制限はないが、酸化物基準のモル百分率表示で、含有量は0.0001%以上が好ましく、0.001%以上がより好ましい。
The content of Cr 2 O 3 is preferably 0.3% or less in terms of mol% based on oxide. Cr 2 O 3 is not only easily mixed from the manufacturing apparatus, but also glass is easily colored even with a small amount. When Cr 2 O 3 is mixed, not only is it easy to attenuate radio waves, but also when measuring light is transmitted through a glass housing made of glass for housing and optical measurement is performed, the measuring light is absorbed by the glass. This makes it impossible to perform highly reliable measurements. Therefore, by setting the content of Cr 2 O 3 to be equal to or less than the upper limit, radio waves for information exchange and electromotive force are less susceptible to interference and attenuation by glass. For this reason, radio waves or the like easily reach the IC tag, and data transmission can be shortened and errors can be suppressed. Furthermore, in the case of optical measurement, by setting the content of Cr 2 O 3 in the housing to the upper limit or less, the measurement light is not easily interfered with by the glass housing, and highly reliable measurement can be performed.
Although the lower limit of Cr 2 O 3 is not particularly limited, the content is preferably 0.0001% or more, and more preferably 0.001% or more, in terms of oxide-based mole percentage.
 SOは清澄剤として作用する成分であり、酸化物基準のモル%表示で0.005%以上が好ましく、0.01%以上がより好ましく、0.02%以上がさらに好ましく、0.03%以上が特に好ましい。ガラス内の泡の個数を減少させるためにもSOは0.5%以下が好ましく、0.3%以下がより好ましく、0.2%以下がさらに好ましく、0.1%以下が特に好ましい。 SO 3 is a component that acts as a fining agent, preferably 0.005% or more, more preferably 0.01% or more, more preferably 0.02% or more, and more preferably 0.03% in terms of mol% on the oxide basis. The above is particularly preferable. In order to reduce the number of bubbles in the glass, SO 3 is preferably 0.5% or less, more preferably 0.3% or less, further preferably 0.2% or less, and particularly preferably 0.1% or less.

In addition, when the glass is used in a shape other than a flat shape, for example, a concave shape or a convex shape, the glass formed into a flat shape or a block shape is reheated and press-molded in a melted state, or the molten glass is pressed. By pouring out onto a mold and press molding, it is molded into a desired shape.
 ガラス中の水分濃度については、式(1)で求められるβ-OH値という指標を使用して管理すればよい。なお、含水量とβ-OH値とは相関関係がある。β-OH値が高いほど、含水量が多いとみなせる。
 β-OH値=(1/t)log10(T/T) ・・・(1)
(ただし、tはガラスの厚さで単位はmm、TはFT-IRによる3846cm-1における透過率で単位は%、TはFT-IRによる3500cm-1付近における最小透過率で単位は%である。)
The moisture concentration in the glass may be managed using an index called β-OH value obtained by the equation (1). There is a correlation between the water content and the β-OH value. It can be considered that the higher the β-OH value, the greater the water content.
β-OH value = (1 / t) log 10 (T 1 / T 2 ) (1)
(Where t is the glass thickness, the unit is mm, T 1 is the transmittance at 3846 cm −1 by FT-IR, the unit is%, and T 2 is the minimum transmittance at around 3500 cm −1 by FT-IR, the unit is %.)
 β-OH値が高いと電波等の減衰等の原因となるため、適正な範囲に制御することが好ましい。β-OH値は2/mm以下が好ましく、1.5/mm以下がより好ましく、1/mm以下がさらに好ましい。β-OH値が上限値より大きいと、電波等が減衰しやすい。またガラスを強化処理した場合に、その効果が徐々に緩和するといった機械的強度が弱まることがあり、遠心分離時など強い条件の元で使用に耐えないことが考えられる。 Since a high β-OH value causes attenuation of radio waves and the like, it is preferable to control within an appropriate range. The β-OH value is preferably 2 / mm or less, more preferably 1.5 / mm or less, and even more preferably 1 / mm or less. When the β-OH value is larger than the upper limit value, radio waves and the like are easily attenuated. In addition, when the glass is tempered, the mechanical strength that the effect gradually relaxes may weaken, and it is considered that the glass cannot be used under strong conditions such as during centrifugation.
 β-OH値の下限値は特に制限はないが、0.2/mm以上が好ましく、0.3/mm以上がより好ましい。β-OH値が下限値以上であると、ガラスの軟化点を下げられ、筐体への成形時に加熱温度を下げられるといった、装置などへの負荷を低減できる。 The lower limit of the β-OH value is not particularly limited, but is preferably 0.2 / mm or more, and more preferably 0.3 / mm or more. When the β-OH value is equal to or higher than the lower limit, the glass softening point can be lowered, and the load on the apparatus or the like can be reduced, such that the heating temperature can be lowered during molding into a casing.
 β-OH値は、水和物や水酸化物などの含水量の多い原料の使用を低減する、原料中への水分混入を抑制する、ガラス製造設備内の水蒸気量を制御する、などにより制御できる。 The β-OH value is controlled by reducing the use of raw materials with high water content, such as hydrates and hydroxides, suppressing moisture contamination in the raw materials, and controlling the amount of water vapor in the glass manufacturing facility. it can.

 自重成形法は、成形後の筐体2の形状に応じた所定の金型上に筐体用透明基材4を設置後、透明基材4を軟化させて、重力により曲げて金型になじませて、所定の形状に成形する方法である。これにより一部に屈曲部を付与した筐体2を作製できる。
[Molding process]
A molding process may be performed in order to produce the housing 2 by providing a bent portion to the housing transparent substrate 4. For example, the molding method used for the transparent substrate for a flat-plate housing includes a self-weight molding method, a vacuum molding method, a press molding method, a draw molding, a blow molding, an injection molding, and an extrusion molding, and the shape of the housing after molding. A desired molding method may be selected according to the above.
In the self-weight molding method, the transparent base material 4 for the housing is placed on a predetermined mold corresponding to the shape of the housing 2 after molding, and then the transparent base material 4 is softened and bent by gravity to fit the mold. It is a method of forming into a predetermined shape. Thereby, the housing | casing 2 which provided the bending part in part can be produced.
 差圧成形法は、筐体用透明基材4を軟化させた状態で透明基材4の表裏面に差圧を与えて、透明基材4を曲げて金型になじませて、所定の形状に成形する方法である。差圧成形法の一態様である真空成形法では、筐体2の形状に応じた所定の成形型上に筐体用透明基材4を設置し、透明基材4上にクランプ金型などの上型を設置し、透明基材4の周辺をシールした後、成形型と透明基材4との空間をポンプで減圧することにより、透明基材4の表裏面に差圧を与える。この際に、補助的に、透明基材4の上面側を加圧してもよい。これにより複雑な屈曲部を付与した筐体2を作製できる。 The differential pressure molding method applies a differential pressure to the front and back surfaces of the transparent base material 4 in a state in which the transparent base material 4 for the case is softened, and bends the transparent base material 4 so as to conform to a mold. It is the method of shape | molding. In the vacuum forming method which is one aspect of the differential pressure forming method, the transparent substrate 4 for the case is installed on a predetermined mold corresponding to the shape of the case 2, and a clamp mold or the like is provided on the transparent substrate 4. After the upper mold is installed and the periphery of the transparent base material 4 is sealed, the space between the mold and the transparent base material 4 is reduced by a pump to apply a differential pressure to the front and back surfaces of the transparent base material 4. Under the present circumstances, you may pressurize the upper surface side of the transparent base material 4 supplementarily. Thereby, the housing | casing 2 which provided the complicated bending part is producible.
 また、差圧成形法の一態様であるブロー成形を実施してよい。ブロー成形では加熱した基材原料からゴブを作製し、ゴブを筐体2の形状に応じた所定の成形型に供給し、ゴブ内に高圧空気を供給し膨らませ筐体2の形状とする。この際に、金型内のゴブをプランジャーなどの棒状金型で成形した後、高圧空気を供給してよい。これにより、瓶形状の筐体2を作製できる。 Also, blow molding, which is an aspect of the differential pressure molding method, may be performed. In blow molding, a gob is produced from a heated base material, and the gob is supplied to a predetermined molding die corresponding to the shape of the casing 2, and high-pressure air is supplied into the gob to expand the casing. At this time, high pressure air may be supplied after the gob in the mold is molded with a rod-shaped mold such as a plunger. Thereby, the bottle-shaped housing | casing 2 is producible.
 プレス成形は、成形後の筐体2の形状に応じた所定の金型(下型、上型)間に筐体用透明基材4を設置し、透明基材4を軟化させた状態で、上下の金型間にプレス荷重を加えて、透明基材4を曲げて金型になじませて、所定の形状に成形する方法である。これにより寸法精度の高い筐体2を作製できる。 In press molding, the housing transparent substrate 4 is placed between predetermined molds (lower mold, upper mold) corresponding to the shape of the molded casing 2 and the transparent substrate 4 is softened. In this method, a press load is applied between the upper and lower molds, the transparent base material 4 is bent and conformed to the molds, and is molded into a predetermined shape. Thereby, the housing | casing 2 with high dimensional accuracy can be produced.
 ドロー成形は、管形状の成形において、セラミックスまたは耐熱金属の上で成形される低粘度の成形体を、長さ方向に引き伸ばしながら冷却して所望の寸法の管や房に連続成形できる方法である。 Draw molding is a method in which a low-viscosity molded body molded on ceramics or refractory metal can be cooled while being stretched in the length direction and continuously formed into tubes and tufts of desired dimensions in tube-shaped molding. .
 これらのうち差圧成形法やプレス成形法は、筐体2の所定の形状に成形する方法として優れており、筐体2の一方の主面は成形型と接触せずに成形できるため、傷、へこみなどの凹凸状欠点を減らせる。
 なお、成形後の筐体の形状に応じて、適切な成形法を選択すればよく、2種以上の成形法を併用してもよい。
Among these, the differential pressure molding method and the press molding method are excellent as methods for molding the housing 2 into a predetermined shape, and one main surface of the housing 2 can be molded without contacting the molding die. Can reduce uneven defects such as dents.
An appropriate molding method may be selected according to the shape of the casing after molding, and two or more molding methods may be used in combination.
 (強化処理)
 筐体用透明基材4および筐体2が無機ガラスである場合、表面圧縮応力層を形成する強化処理方法として、物理強化法や化学強化法が利用できる。ガラス主面が強化処理された被加工物は、機械的強度が高くなる。いずれの強化手法を採用してもよいが、厚みが薄くかつ表面圧縮応力(CS)値が大きなガラスを得る場合には、化学強化処理が好ましい。
(Strengthening process)
When the transparent base material 4 for a housing and the housing 2 are inorganic glass, a physical strengthening method or a chemical strengthening method can be used as a strengthening treatment method for forming a surface compressive stress layer. A workpiece whose glass main surface is tempered has high mechanical strength. Any tempering method may be adopted, but chemical tempering treatment is preferable when a glass having a small thickness and a large surface compressive stress (CS) value is obtained.
 [物理強化処理]
 物理強化処理(風冷強化処理)は、軟化点付近まで加熱した無機ガラスの主面を風冷などにより急速に冷却する手法である。
[Physical enhancement processing]
The physical strengthening treatment (air cooling strengthening treatment) is a method of rapidly cooling the main surface of the inorganic glass heated to near the softening point by air cooling or the like.
 [化学強化処理]
 無機ガラスを化学強化処理する場合、表面に圧縮応力層が形成され、強度及び耐擦傷性が高められる。化学強化処理においては、450℃弱の溶融塩で、無機ガラスの主面に存在するイオン半径が小さいアルカリ金属イオン(典型的にはLiイオン、Naイオン)を、イオン半径のより大きいアルカリイオン(典型的にはLiイオンに対してはNaイオン又はKイオンであり、Naイオンに対してはKイオンである。)に交換することで、ガラス表面に圧縮応力層を形成する処理である。化学強化処理は従来公知の方法によって実施でき、一般的に硝酸カリウム溶融塩にガラスを浸漬する。この溶融塩に炭酸カリウムや炭酸ナトリウムを10質量%程度入れて使用してもよい。これによりガラスの表層のクラックなどを除去でき高強度のガラスが得られる。化学強化時に硝酸カリウムに硝酸銀などの銀成分を混合することで、ガラスがイオン交換され銀イオンを表面に有し抗菌性を付与できる。化学強化処理は1回に限らず、例えば異なる条件で2回以上実施してもよい。
[Chemical strengthening treatment]
When chemically strengthening inorganic glass, a compressive stress layer is formed on the surface, and strength and scratch resistance are improved. In the chemical strengthening treatment, an alkali metal ion (typically Li ion, Na ion) having a small ion radius existing on the main surface of the inorganic glass with a molten salt of less than 450 ° C. is converted into an alkali ion having a larger ion radius ( Typically, Na ions or K ions are used for Li ions, and K ions are used for Na ions.), Thereby forming a compressive stress layer on the glass surface. The chemical strengthening treatment can be performed by a conventionally known method, and generally the glass is immersed in molten potassium nitrate. About 10% by mass of potassium carbonate or sodium carbonate may be used in this molten salt. Thereby, the crack of the surface layer of glass, etc. can be removed, and high strength glass is obtained. By mixing a silver component such as silver nitrate with potassium nitrate at the time of chemical strengthening, the glass is ion-exchanged to have silver ions on the surface and impart antibacterial properties. The chemical strengthening treatment is not limited to once, and may be performed twice or more under different conditions, for example.
 無機ガラスは主面に圧縮応力層が形成されており、その圧縮応力層の圧縮応力(CS)は、500MPa以上が好ましく、550MPa以上がより好ましく、600MPa以上がさらに好ましく、700MPa以上が特に好ましい。圧縮応力(CS)が高くなると強化ガラスの機械的強度が高くなる。一方、圧縮応力(CS)が高くなりすぎるとガラス内部の引張応力が極端に高くなるおそれがあるため、圧縮応力(CS)は1800MPa以下が好ましく、1500MPa以下がより好ましく、1200MPa以下がさらに好ましい。 The inorganic glass has a compressive stress layer formed on the main surface, and the compressive stress (CS) of the compressive stress layer is preferably 500 MPa or more, more preferably 550 MPa or more, further preferably 600 MPa or more, and particularly preferably 700 MPa or more. As the compressive stress (CS) increases, the mechanical strength of the tempered glass increases. On the other hand, if the compressive stress (CS) becomes too high, the tensile stress inside the glass may become extremely high. Therefore, the compressive stress (CS) is preferably 1800 MPa or less, more preferably 1500 MPa or less, and even more preferably 1200 MPa or less.
 無機ガラスの主面に形成される圧縮応力層の深さ(DOL)は、5μm以上が好ましく、8μm以上がより好ましく、10μm以上がさらに好ましい。一方、DOLが大きくなりすぎるとガラス内部の引張応力が極端に高くなるおそれがあるため、圧縮応力層の深さ(DOL)は180μm以下が好ましく、150μm以下がより好ましく、80μm以下がさらに好ましく、典型的には50μm以下である。 The depth (DOL) of the compressive stress layer formed on the main surface of the inorganic glass is preferably 5 μm or more, more preferably 8 μm or more, and even more preferably 10 μm or more. On the other hand, if the DOL becomes too large, the tensile stress inside the glass may become extremely high, so the depth of the compressive stress layer (DOL) is preferably 180 μm or less, more preferably 150 μm or less, and even more preferably 80 μm or less, Typically, it is 50 μm or less.
 (研削・研磨加工工程)

(Grinding / polishing process)
When the housing transparent substrate 4 or the housing 2 is particularly inorganic glass, at least one main surface thereof may be ground and polished. When there is a layer containing a large amount of a specific metal (for example, tin) on the main surface of the transparent base material 4 for the case, radio waves for information exchange and power generation are subject to interference and attenuation by this layer. Can be considered. For this reason, it is considered that by removing a layer containing a large amount of a specific metal by polishing or grinding, radio waves and the like can easily reach the IC tag, and data transmission can be shortened and errors can be suppressed.
 (孔あけ加工工程)
 筐体用透明基材4または筐体2の少なくとも一部に孔を形成してもよい。孔は筐体用透明基材4または筐体2を貫通していても、貫通していなくてもよい。孔あけ加工は、ドリルやカッタなどの機械加工でも、フッ酸などの薬品を使用したエッチング加工でもよく、特に制限はない。

Examples of the surface treatment layer include an antiglare treatment layer, an antireflection treatment layer, an antifouling treatment layer, and a barrier layer, and these may be used in combination. The surface on which the surface treatment layer is formed may be any surface of the housing transparent substrate 4 or the first main surface 4a or the second main surface 4b of the housing 2.
 [防眩処理層]
 防眩処理層とは主に反射光を散乱させ、光源の映り込みによる反射光の眩しさを低減する効果をもたらす層のことである。防眩処理層は筐体用透明基材4自体または筐体2自体の表面を加工して形成してもよく、別途堆積形成してもよい。防眩処理層の形成方法として、例えば、筐体用透明基材4または筐体2の少なくとも一部に化学的あるいは物理的な方法で表面処理を施し、所望の表面粗さの凹凸形状を形成する方法を使用できる。また、形成方法として、筐体用透明基材4または筐体2の少なくとも一部に処理液を塗布あるいは噴霧して、板上に凹凸構造を形成してもよい。
 さらに熱的な方法により筐体用透明基材4または筐体2の少なくとも一部に凹凸構造を形成してもよい。
[Anti-glare treatment layer]
The antiglare treatment layer is a layer that mainly scatters reflected light and brings about an effect of reducing glare of reflected light due to reflection of a light source. The antiglare treatment layer may be formed by processing the surface of the housing transparent substrate 4 itself or the housing 2 itself, or may be separately deposited. As a method for forming the antiglare treatment layer, for example, surface treatment is performed on at least a part of the transparent substrate 4 for the case or the case 2 by a chemical or physical method to form an uneven shape with a desired surface roughness. You can use the method you want. Further, as a forming method, a concavo-convex structure may be formed on the plate by applying or spraying a treatment liquid to at least a part of the housing transparent substrate 4 or the housing 2.
Furthermore, you may form an uneven | corrugated structure in at least one part of the transparent base material 4 for housing | casing, or the housing | casing 2 with a thermal method.
 化学的方法による凹凸構造形成方法として、具体的にはフロスト処理を施す方法が挙げられる。フロスト処理は、例えば、フッ化水素とフッ化アンモニウムの混合溶液に、被処理体がガラスの場合、ガラスを浸漬してエッチングする。
 物理的方法による凹凸構造形成方法として、例えば、結晶質二酸化ケイ素粉、炭化ケイ素粉等を加圧空気で筐体用透明基材4または筐体2の少なくとも一方の主面に吹きつけるいわゆるサンドブラスト処理や、結晶質二酸化ケイ素粉、炭化ケイ素粉等を付着させたブラシを水で湿らせて、筐体用透明基材4または筐体2の少なくとも一方の主面を研磨する方法等で行われる。
 なかでも、化学的方法であるフロスト処理は、被処理体表面にマイクロクラックを生じ難く、強度の低下が生じ難いため、好ましく利用できる。
As a method for forming a concavo-convex structure by a chemical method, specifically, a method of performing a frost treatment can be mentioned. In the frost treatment, for example, when the object to be treated is glass in a mixed solution of hydrogen fluoride and ammonium fluoride, the glass is immersed and etched.
As a method for forming a concavo-convex structure by a physical method, for example, so-called sand blasting, in which crystalline silicon dioxide powder, silicon carbide powder, or the like is sprayed onto at least one main surface of the casing transparent substrate 4 or the casing 2 with pressurized air. Alternatively, it is performed by a method in which a brush to which crystalline silicon dioxide powder, silicon carbide powder or the like is attached is moistened with water and at least one main surface of the housing transparent substrate 4 or the housing 2 is polished.
Of these, the frost treatment, which is a chemical method, can be preferably used because microcracks are unlikely to occur on the surface of the object to be processed, and strength is unlikely to decrease.
