    • PROBLEM TO BE SOLVED: To provide a case structure of a fluid pressure device which enables the case to be connected with a body certainly and easily and also, the interior of the case to be visually recognized more certainly and easily compared with conventional case structures, and thus, enables the upgrading of the case durability to be ensured.SOLUTION: The case structure of the fluid pressure device includes a filter 12 which constitutes a fluid pressure unit 10, and this filter 12 comprises a first body 20, a case unit 22 connected with the lower part of the first body 20, and a filter unit 24 accommodated inside the case unit 22. In addition, the case unit 22 comprises an outer case 40 of a bottomed cylindrical shape made of a transparent material with permeability and an inner case 42 to be inserted into the interior of the outer case 40. The case unit 22 is introduced into a fitting hole 36 which is opened in the lower part of the first body 20, and then is rotated. By so doing, a projecting part 58 and a retaining wall 56 arranged on the outer circumferential surface of the case unit 22, are fitted into a support part 38 arranged in the fitting hole 36. As a result, both the projecting part 58 and the retaining wall 56 are placed in a connected state.
    • 解决的问题:为了提供能够使壳体能够确实且容易地与身体连接的流体压力装置的壳体结构,并且与现有技术相比,能够更可靠和容易地视觉识别外壳的内部 壳体结构,从而能够提高壳体的耐久性以确保。 解决方案:流体压力装置的壳体结构包括构成流体压力单元10的过滤器12,该过滤器12包括第一主体20,与第一主体20的下部连接的壳体单元22, 以及容纳在壳体单元22内的过滤器单元24.此外,壳体单元22包括由具有透气性的透明材料制成的有底圆柱形的外壳40和插入外部的内部的内壳体42 壳体单元22被引入到在第一主体20的下部中打开并随后旋转的装配孔36中。 通过这样做,布置在壳体单元22的外圆周表面上的突出部分58和保持壁56被装配到布置在装配孔36中的支撑部分38中。结果,突出部分58和 挡土墙56处于连接状态。 版权所有(C)2013,JPO&INPIT

    • A filter apparatus removes foreign substances contained in raw water by passing the raw water through a filter layer (8) made up of a particulate filter medium disposed in a filter tank (1). The apparatus is made up of: a partition wall (2) provided inside the filter tank (1) so as to extend from an upper end of the filter tank (1) downward while leaving a space to a bottom surface (7) of the filter tank (1) such that the filter tank (1) is divided into a supply portion (4) having a raw water supply port (3) and a discharge portion (6) having a backwashed water discharge port (5); wherein the bottom surface (7) of the filter tank (1) is inclined from the discharge portion (6) downward toward the supply portion (4), the bottom surface (7) having the filter medium spread thereon in a manner to cover both the supply portion (4) and the discharge portion (6), the filter medium being filled to such a depth that an upper end of the filter medium reaches at least a bottom end of the partition wall (2); water collecting pipe (10) embedded inside the filter medium for collecting filtered water; and backwashing device for backwashing the filter medium.
