摘要： A zoom lens system shifts the position of front and rear lens groups relative to each other in the direction of the optical axis to change its focal length, by moving a lens barrel back and forth in the axial direction. The lens barrel is formed with cutouts in its rear portion for receiving therein parts and elements projecting forwardly from the plane in which an exposure aperture is located when the lens barrel is retracted, so as to reduce the thickness of the camera with the retracted zoom lens. A focal length changing mechanism comprises a fixed cam and a lever attached to the lens barrel which is turned by the cam when the lens barrel moves back and forth to shift one lens group, thereby changing the focal length of the zoom lens to desired focal lengths. To correct the changes in focus of the zoom lens caused by the change of focal length, an adjusting member is provided in the focal length changing mechanism. An encoder is provided in the camera to detect the shifted axial positions of the lens barrel.
摘要翻译：变焦透镜系统通过沿轴向方向前后移动镜筒来使前后透镜组相对于光轴的方向移动位置，以改变其焦距。镜筒在其后部形成有切口，用于在透镜镜筒缩回时从其中暴露孔位于其中的平面向前突出的部件和元件，以便缩小相机的缩小后的变焦镜头的厚度。焦距改变机构包括固定凸轮和附接到镜筒的杆，当透镜镜筒前后移动以移动一个透镜组时由凸轮转动，从而将变焦透镜的焦距改变为期望的焦距。为了校正焦距变化引起的变焦镜头的焦点变化，调焦部件设置在焦距变化机构中。在相机中设置有一个编码器来检测透镜镜筒的偏移的轴向位置。

摘要： A rotary compressor for use with refrigerating apparatuses such as freezing refrigerators, freezers, showcases for household or commercial use incorporates a mechanism in a compressor unit. When a space to be freezed is freezed in a on-off operation mode, the mechanism prevents a large amount of high temperature refrigerant gas in a closed casing of the compressor from being discharged to an evaporator during the suspension of the operation of the compressor.

摘要： A heater power controller for an ink jet printer wherein the output of a comparator making a comparison between a detection signal of the temperature of an ink in a print head of the ink jet printer and a reference signal is chopped by a clock having a predetermined period so as to be converted into a chopper signal, by which the supply of the power to a heating means provided in the head is controlled. A regulating device for regulating the duty ratio of the chopper signal is provided. Each of pulses constituting the chopper signal is made out of phase with a pulse supplied to other pulse-driven load.

摘要： An apparatus for detecting the density (concentration) of toner in a developer for an electrostatic recording apparatus includes an operatively moveable surface for carrying developer onto an electrostatic latent image bearing member during image development, a scraper element having at least a flat surface for scraping developer from the movable surface in a substantially steady and uniform stream along the flat face, and a substantially flat detection coil assembly having oppositely-directed faces. The coil assembly is mounted on, spaced apart from, and substantially parallel to the flat face of the scraper so that the stream of developer passes along both coil assembly faces directly after being scraped from the moveable surface, thereby enhancing the toner density detection sensitivity of the coil assembly.
摘要翻译：用于检测静电记录装置的显影剂中的调色剂的浓度（浓度）的装置包括：用于在图像显影期间将显影剂承载在静电潜像承载部件上的可操作地移动的表面，至少具有用于刮刮显影剂的平坦表面的刮刀元件从可动表面沿着平坦的表面以基本稳定和均匀的流体，以及具有相对方向的面的基本平坦的检测线圈组件。线圈组件安装在刮板的平坦表面上并基本上平行于刮板的平面，使得显影剂流在从可移动表面刮下之后直接沿着两个线圈组件表面通过，从而增强了调色剂浓度检测灵敏度线圈组件。
