摘要： An illuminated push-button switch assembly has a casing slidably mounting a manipulation member provided at its exterior end with an indicating plate. A light source is mounted in the casing to illuminate the indicating plate. The switch assembly further has shutter means constituted by a filter member and a drive member. The filter member is rotatably supported at its one end on the casing, while the filter member is rotatably supported at its intermediate portion by the manipulation member. The free end of the drive member is engageable with the filter member at the portion of the latter near the axis of rotation. As the slider is moved by manual operation of the manipulation member, the drive member is rotated to cause a rotation of the filter, so that the state of illumination of the indicating plate is changed in accordance with the state of the push-button switch. A large displacement of the driving member and, hence, a large rotation angle of the filter member, is obtained even by a small stroke of the slider, thanks to a suitable selection of positions of the operating and supporting points.

摘要翻译： 照明按钮开关组件具有可滑动地安装在其外端设置有指示板的操作构件的壳体。 光源安装在壳体中以照亮指示板。 开关组件还具有由过滤构件和驱动构件构成的闸门装置。 过滤构件的一端可旋转地支撑在壳体上，而过滤构件通过操纵构件可旋转地支撑在其中间部分。 驱动构件的自由端可以在过滤构件的靠近旋转轴线的部分处与过滤构件接合。 当通过操作构件的手动操作来移动滑块时，驱动构件被旋转以引起过滤器的旋转，使得指示板的照明状态根据按钮开关的状态而改变。 由于操作和支撑点的位置的适当选择，即使通过滑块的小行程也可获得驱动构件的大的位移以及因此的过滤构件的大的旋转角度。

摘要： A Schmitt trigger circuit has a first transistor for inversion having a base supplied with an input voltage. A level shift diode shifts an emitter voltage of the first transistor from a reference level, and a second transistor for switching has a collector and an emitter respectively coupled to an anode and a cathode of the level shift diode. The emitter of the second transistor is coupled to a first power source voltage. A switching part is coupled between a base of the second transistor and a second power source voltage higher than the first power source voltage, for controlling switching of the second transistor. An output circuit is coupled between the first and second power source voltages and supplied with the input voltage through the first transistor for outputting the output voltage. The switching part is controlled responsive to a voltage from the output circuit so as to close when the logic level of this voltage is the high level, thereby turning the second transistor ON.

摘要： A transfer circuit 25 includes two sets of an input circuit 52A and an output circuit 53B, which allows bidirectional transfer. The input circuit 52A decomposes external input data signals DI11A and DI12A to signals on lines L11 to L14 in synchronism with a clock signal CLK in order to reduce the frequency thereof. The output circuit 53B composes the decomposed signals in synchronism with the clock signal CLK to regenerate the original signals and output them as external output data signals DO11B and DO12B. Signals on either the lines L11 to L14 or L21 to L24 are selected by a multiplexer 57 to provide to a main body circuit.
