    • A lens barrel includes an optical lens having an optical axis, an operation ring substantially cylindrical and operable about the optical axis to move the optical lens along the optical axis thereof, and a slidable contact member slidably in contact with the inner circumferential surface of the operation ring, the slidable contact member providing a specific load against the inner circumferential surface thereof. The operational torque of the operation force is changed when the slidable contact member moves in the optical axis direction by changing its contact area with the inner circumferential surface of the operation ring.
    • 透镜镜筒包括具有光轴的光学透镜,操作环基本上为圆柱形并且围绕光轴可操作以沿着其光轴移动光学透镜,以及可滑动地与操作的内周表面接触的可滑动接触构件 所述可滑动接触构件对其内周面提供特定的载荷。 当可滑动接触构件通过改变与操作环的内周表面的接触面积沿光轴方向移动时,操作力的操作扭矩改变。

    • There is disclosed a reduction gear apparatus including a first member, a second member connected to the output shaft, a press member that rotates together with the input shaft to press part of the second member so as to bring the part into contact with the first member, and a control member for controlling rotation of the first member about the output shaft. A high speed reducing ratio can be obtained with respect to rotation of a motor, and a clutch function for connecting/disconnecting power transmission to/from the output shaft by controlling rotation of the first member and other functions can be imparted to the gear reduction apparatus.

    • An apparatus for firmly mounting solid-state image sensors to an image splitting prism in which a mounting glass block is bonded to an image splitting prism surface or to a glass plate bonded to a prism. A metal film is formed on the glass block, and a preliminary solder layer is formed on the metal film to improve wettability. A gap between the preliminary solder layer and a meltable metal member formed on a caging of a solid-state image sensor is filled with a meltable metal having a predetermined thickness, thus bonding the preliminary solder layer and the meltable metal member. When this construction can be obtained, the total thickness of the metal film can be reduced to 1 .mu.m or less.
    • 一种用于将固态图像传感器牢固地安装到其中安装玻璃块结合到图像分离棱镜表面的图像分离棱镜或结合到棱镜的玻璃板的装置。 在玻璃块上形成金属膜,在金属膜上形成预备焊料层,提高润湿性。 预先焊接层与形成在固态图像传感器的笼状物上的可熔融金属部件之间的间隙填充有具有预定厚度的可熔融金属,从而结合初步焊料层和可熔融金属部件。 当可以获得这种结构时,金属膜的总厚度可以减小到1μm以下。
