    • The present invention provides an image processing apparatus capable of forming a sharp image of a detection mark formed in a plane. The image processing apparatus comprises a camera unit (1) comprising a lens system (12) and a photodetecting device (13) inclined at a predetermined angle to the optical axis (L') of the lens system. The camera unit (1) is disposed with the optical axis (L') of the lens system (12) inclined at a predetermined angle to a perpendicular line (L) to the plane including the detection mark so that the difference in length between respective sections of light paths between diametrically opposite portions of the detection mark and the lens system is canceled by the difference in length between respective sections of the same light paths between the lens system and the photodetecting device.

    • Disclosed is an air motor having an engine pack (with a rotor provided with front and rear retainers, a stator, and vanes) which can be assembled and replaced even by an unskilled person. An air supply joint is engaged with guide projections formed on the inner peripheral surface of a housing, with its forward end portion held in contact with the rear retainer; the forward end portion being fastened by a nut member which is threadedly engaged with the housing. On the rear face of the forward end portion are formed a plurality of first projections produced of a rigid synthetic resin, and on the front face of the nut member corresponding to the first projection are formed a plurality of second projections, so that a firm relation of engagement is established by an elastic force of restoration of the first projection; that is, the nut member will not accidentally become loose owing to the locking effect of the first and second projections. Furthermore, the engine pack can be drawn out straight by unfastening the nut member by a jig.
    • 公开了一种具有发动机组(具有设置有前后保持器,​​定子和叶片的转子)的空气马达,其甚至可以由不熟练的人组装和更换。 供气接头与形成在壳体的内周面上的引导突起接合,其前端部保持与后保持器接触; 前端部分由与壳体螺纹接合的螺母构件紧固。 在前端部的后表面形成有由刚性合成树脂制成的多个第一突起,并且在与第一突起相对应的螺母构件的前表面上形成有多个第二突起,从而形成牢固的关系 通过第一突起的恢复弹性力建立接合; 也就是说,由于第一和第二突起的锁定效应,螺母构件不会意外变松。 此外,通过用夹具松开螺母构件,可以将发动机组件直接拉出。
