    • 【課題】構造が簡単で製造コストのあまりかからない、早回し作業の容易なレンチを提供する。
      【解決手段】レンチ部11とこのレンチ部11に着脱自在に取り付けられる握持柄部15との組とし、レンチ部11は、短杆部12aと長杆部12bとを略L字形状に連設してレンチ本体12を形成し、このレンチ本体12の長杆部12bの基端部側外周に軸方向に沿って嵌合軸部13を設けたものとする。 そして握持柄部15は、前記嵌合軸部13が嵌合可能に穿設された嵌合孔16と該嵌合孔16の周縁から外周に渡って孔軸方向奥側に向かい切り欠かれた収容部17とを有するものとし、レンチ部11側の嵌合軸部13を握持部15側の嵌合孔16に嵌挿したときに短杆部12aが収容部17内に収容されるようにする。

    • PROBLEM TO BE SOLVED: To provide a saw which certainly holds the fixing of the handle part of a saw body and the grip attached thereto over a long period of time without mutually causing play between the handle part and the grip and loosening the fixing of them to ensure good sawing work over a long period of time. SOLUTION: The saw has the saw body constituted by integrally forming a length-of-blade part 10 and the handle part 20 and the grip 30 attached to the handle part 20 of the saw body so as to be externally fitted thereto. A material replacing region 21, which is constituted by replacing and integrating a part of the handle part 20 by a separate member, is formed to the handle part 20 of the saw body while a female screw hole 22 is formed to the material replacing region 21 and the grip 30 is directly fixed to the handle part 20 by a screw using the female screw hole 22.

    • PROBLEM TO BE SOLVED: To provide a fluid bearing device capable of blocking outflow of working fluid such as oil to the outside of a bearing, preventing deterioration of rigidity in a radial bearing, keeping favorable the clearances of a thrust bearing and a radial bearing so as to achieve stable rotation in a non-contact condition, and maintaining excellent performance of a bearing at a low temperature.
      SOLUTION: A shaft 2 is composed of high manganese chrome steel or stainless steel. The whole of a sleeve 1 is formed by sintered metal made up of metal particles including 60 wt% or more of iron or copper. A resin, metal or water glass is impregnated in a vacancy existing in the surface of the sintered metal so as to be hardened. While outflow of working fluid such as oil 11 to the outside of a bearing through the vacancy in the surface of the sleeve 1 can be blocked, by so doing, relative rotation of a shaft 2 can be prevented from becoming heavy even if the viscosity of oil 11 is increased due to low temperatures.

    • 要解决的问题:为了提供能够阻止诸如油的工作流体向轴承外部流出的流体轴承装置,防止径向轴承的刚性劣化,保持推力轴承的间隙和 径向轴承,以在非接触状态下实现稳定的旋转,并且在低温下保持轴承的优异性能。 解决方案:轴2由高锰铬钢或不锈钢组成。 整个套筒1由包含60重量%或更多的铁或铜的金属颗粒构成的烧结金属形成。 将树脂,金属或水玻璃浸渍在存在于烧结金属表面的空位中以使其硬化。 当通过套筒1的表面中的空隙将油11等工作流体流出到轴承外部时,即使粘合剂的粘度也可以防止轴2的相对转动, 油11由于低温而升高。 版权所有(C)2005,JPO&NCIPI
