【0038】これら試料ガラスについて以下の方法で透視性試験、電磁遮蔽試験、防音試験を行った。 The see-through test on these glass samples by the following method, an electromagnetic shielding test was carried out soundproofing test. 透視性試験方法 ;テレビジョンの手前約 5cmのところに試料ガラスを配し、さらに試料ガラスの約50cm手前の位置から試料ガラスを介してテレビ画像を透視し、画像識別の良否について試験した。 Fluoroscopy testing method; arrange glass samples at the television front about 5 cm, seen through the television image further through the glass sample from approximately 50cm before the position of the sample glass was tested for quality of image identification.

【0039】 電磁遮蔽試験方法 ;公知のMIL-STANDARD 2 The electromagnetic shielding test method; known MIL-STANDARD 2
85による測定法に準拠し、電波吸収函体内に試料ガラスをセットし一方に送信アンテナ、他方に受信アンテナを対設し、周波数1GHzにおける電磁波の減衰率(dB) (ブランクテストとの対比による)を測定記録した。 Conforming to the measurement method by 85, and oppositely arranged receiving antennas transmit antennas, the other one set of the sample glass in the radio wave absorbing box making body, electromagnetic wave attenuation constant at a frequency of 1 GHz (dB) (by comparison with the blank test) It was measured and recorded.

【0040】 防音試験方法 ;試料ガラスの一方のガラス板 (例えば図1におけるガラス板3)を上側、他方のガラス板 (同様にガラス板4)を下側にして水平にセットし、 The upper, set horizontally to the other glass plate (glass plate 4 as well) on the lower side (the glass plate 3, for example in FIG. 1) one of the glass plates of the glass sample; [0040] Soundproofing Test method
上側ガラス板中央部上方約30cmの位置より該ガラス板に向け金属玉を落下し、他方下側ガラス板中央部下方約20 Falling metal ball toward to the glass plate from the position of the upper glass plate central portion upwardly about 30 cm, the other lower glass plate central portion downwardly about 20

騒音測定機により騒音レベルを計測するもので、金属玉とガラス板との衝突に際して極大値を示す周波数6300± Intended for measuring the noise level by the noise measuring frequency 6300 ± showing a maximum value upon collision between the metal ball and the glass plate
1000Hzにおける騒音減衰率 (dB)(単板ガラスをセットし試験した場合との対比による) を測定記録した。 Noise attenuation rate of 1000Hz a (dB) (by comparison with the case of setting the sheet glass test) were measured and recorded.

【0041】 〔結果〕比較例1においては透視性は勿論問題なく良好であるが、電磁波減衰率は数dB程度とブランクと比べ顕著な差異はなく、不充分である。 [0041] [Results] Although through property in Comparative Example 1 is good without of course problems, the electromagnetic wave attenuation is not significant difference compared to the number dB about the blank, is insufficient. なお騒音減衰率は単板ガラスに対し約 8dB前後の減衰が認められるが、聴覚的には元の音量の 1/2 を越え、充分とはいえない。 Although noise attenuation rate of the attenuation of about 8dB before and after for the single-sheet glass is observed, the audible beyond the 1/2 of the original volume, it can not be said enough.

【0042】比較例2においても透視性に問題はない。 [0042] There is no problem with the see-through even in Comparative Example 2.
騒音減衰率は単板ガラスに対し14〜17dBの減衰が認められ、聴覚的には元の30〜40%程度の減衰となり、有効と判断される。 Noise attenuation rate with respect to the sheet glasses attenuation of 14~17dB recognized, audible to become the original about 30-40% attenuation, is determined to be valid. しかし電磁遮蔽率は10dB以下で格別の効果は認められず、本発明の目的からすれば不充分である。 But electromagnetic shielding factor is not observed significant effect at 10dB less, is insufficient if the purpose of the present invention.

しかし電磁遮蔽率は10〜15dB程度と低く、本発明の目的からすれば不充分である。 But electromagnetic shield factor is as low as about 10 to 15 dB, is insufficient if the purpose of the present invention.

【0045】実施例1〜3は、いずれも充分透視可能であり、電磁遮蔽率は実施例1において30dB前後、実施例2、3において40〜60dB程度で、いわゆる通常の電磁遮蔽体と称されるものと同様な効果を奏する。 [0045] Examples 1-3 are both capable enough perspective, 30 dB before and after the electromagnetic shielding ratio Example 1, in 40~60dB about in Examples 2 and 3, referred to as the so-called normal electromagnetic shield the same effects as shall. また騒音減衰率は13〜17dBとほぼ比較例2、4と同程度であり、聴覚的には元の30〜40%程度とその効果が認められる。 The noise attenuation factor is approximately the same as Comparative Examples 2 and 4 and 13~17DB, the auditory observed, the effect of the original order of 30-40%.
