Description
第1の実施形態は、本発明をオイルストレーナに適用したものである。図1は、実施形態に係るオイルストレーナの正面図である。図2は、実施形態に係るオイルストレーナの平面図である。図3は、図1及び図2に示すIII−III線におけるオイルストレーナの断面図である。図4は、図3に示すIV−IV線におけるオイルストレーナの断面図である。図5は、図3に示すオイルストレーナの一部拡大図である。図6は、図4に示すオイルストレーナの一部拡大図である。
次に、第2の実施形態について説明する。第2の実施形態は、基本的に第1の実施形態と同様であるが、第一容器部2及び第二容器部3の材質と、レーザー溶着の方法と、のみ第1の実施形態と相違する。このため、以下の説明では、第1の実施形態と相違する点のみ説明し、第1の実施形態と同様の説明を省略する。
Control Welding)工法に用いる光半透過性の樹脂により形成する。ACW工法とは、オリヱント化学工業株式会社により提案されているレーザー溶着工法(特許第4102424号公報参照)である。具体的には、熱可塑性樹脂にレーザー吸収材等を含有させることにより吸光度を0.07〜3.0とした光半透過性の樹脂を作製し、この光半透過性の樹脂にレーザー光の少なくとも一部を吸収させることで、同じ素材の光半透過性の樹脂をレーザー溶着する工法である。
次に、第3の実施形態について説明する。
図9は、実施例における第一容器部及び第二容器部の正面図である。図10は、実施例における第一容器部及び第二容器部の底面図である。図11は、実施例におけるメッシュ部材の平面図である。
実施例5では、第一の樹脂層として、頂部に開口が形成されたハーフドーム状の第一部材を作製し、第二の樹脂層として、平板状の第二部材を作製し、金属層として、第一部材と第二部材との間に挟み込まれるメッシュ部材を作製した。
実施例6として、実施例5と同じ形状の第一部材、第二部材及びメッシュ部材を作製した。
比較例2として、実施例5と同じ形状の第一部材、第二部材及びメッシュ部材を作製した。
実施例5,6及び比較例2について、気密性試験を行った。気密性試験は、第一部材の開口に耐圧ホースの一端を接続し、耐圧ホースの他端を圧力ゲージ付コンプレッサーに接続した。水を満たした水槽に実施例5,6及び比較例2の中空部品を入れ、各中空部品の内部をコンプレッサーで加圧した。そして、各中空部品の内部の圧力であるゲージ圧を測定し、ゲージ圧が0.15MPa及び0.25MPaのときに第一部材と第二部材との接合部から気泡が漏れたか否かを観察した。観察結果を表2に示す。
