At least a part of a gas introduction route for introducing the higher-pressure gas into the communication hole is formed on the discharge valve formed from a thin plate. In addition, a part of the gas introduction route formed on the discharge valve is sealed by a member disposed on a surface facing the discharge valve.

摘要： A mold 25 for molding semiconductor chips 23 and 24 serving as a light emitting element and a light receiving element, respectively, is made of a material capable of transmitting light. A groove 27 is formed on the region where light is emitted from and incident on the semiconductor chips so that it constitutes a reflecting face. Thus, the light is emitted and incident through the side E of the mold. In this configuration, the outer size of the light receiving element or light emitting element can be minimized, and the module provided with these semiconductor chips can also be miniaturized.

摘要： An FM/FMX stereophonic receiver is capable of receiving an FM or an FMX stereophonic broadcast signal. The FM stereophonic broadcast signal includes a stereo sum signal and stereo difference signal, whereas the FMX stereophonic broadcast signal further includes a compressed stereo difference signal and an FMX ID signal indicating the FMX stereophonic broadcast signal. The FM/FMX stereophonic receiver has a stereo demodulator for receiving said broadcast signal and for producing left and right stereo signals, a detector for detecting the field strength of the receiving signal, and a noise reducer, which may be a circuit for changing the mode from stereophonic mode to monaural mode or a high cut circuit for attenuating the signals of high frequency region, for reducing noise signals contained in the left and right stereo signals. The FM/FMX stereophonic receiver further has a detector for detecting the FMX ID signal and a disabling circuit for disabling the noise reducer when the FMX ID signal is detected by the detector. Instead of the disabling circuit, a timing control circuit may be provided for changing the timing at which the noise reducer starts to activate in response to the detection of the FMX ID signal.
