    摘要： A compressor includes a plurality of pistons, a shaft and a wobble plate rotatably and swingably connected with said shaft so that the pistons are reciprocated in accordance with the wobbling movement of the wobble plate. The capacity of the compressor is varied in accordance with the inclining angle of the wobble plate. The actual capacity of the compressor is detected by the magnetic sensor. The compressor has a through member at the lower most portion of the pressure chamber provided in the housing and the slider is slidably connected with the through member. The slider also rotatably connected with the wobble plate so that the wobbling movement of the wobble plate makes the slider reciprocate along with the through member. Such movement of the slider is detected by the magnetic sensor.

    摘要： A semiconductor light-emitting device fabricated as a double hetero-structure InGaAsP/InP-type laser. The laser includes a buffer layer made of a semiconductor. The buffer layer is located at the upper edge of the flow region of electrons as seen from the active layer. The conductivity type of the buffer layer is opposite to that of a clad layer located at the upper edge of the flow region of electrons seen from the buffer layer. A, the band gap of the buffer layer is wider than that of the active layer but narrower than that of a clad layer adjacent to the buffer layer. The thickness of the buffer layer does not exceed the diffusion length of the electrons injected into the buffer layer.

    摘要： A digital pad switch inserted in each highway of a time-division speech network in which there are disposed on the backward side of the speech network time switches, each time switch reading out speech information from a speech memory in the order of the memory cell address, assigning a memory cell address by the output from a channel counter. The digital pad switch is arranged so that it may send out, under the control of a common control unit, a selected converted input signal corresponding to an input signal from the input to the digital pad switch, the converted input signal respectively having been attenuated as compared the input signal by predetermined amounts and also sending out a converted input signal corresponding to a zero level signal regardless of the magnitude of the input signal.When cutting off a speech path set up in the time-division speech network, the digital pad switch is controlled by the common control unit so that the digital pad switch sends out the zero level signal as a signal of the speech path passing through the digital pad switch, and after writing the zero level signal in the speech memory of the time switch on the backward side, the speech path is cut off.A continuous tone signal passing through the time-division speech network is inputted into the digital pad switch. The digital pad switch is controlled by the common control unit to selectively send out the zero level signal for a desired period of time, thereby turning ON and OFF the tone signal. When sending out a howler tone, the amount of attenuation of the tone signal is decreased under the control of the common control unit in a stairstep manner. When testing a multi-frequency signal receiver, a multi-frequency signal transmitter and the multi-frequency signal receiver under test are connected to the backward and the forward side of the time-division speech network, respectively. A path is set up between them and then a signal on the path is attenuated variously by the digital pad switch in order to vary the level of the input signal to the multi-frequency signal receiver.Thus, the present invention permits efficient use of the digital pad switch.
