IPC: H01S5/06
Filed: 1993-10-27
Abstract: PURPOSE:To provide a semiconductor laser modulation circuit device wherein parasitic inductance can be lowered and a semiconductor laser can be modulated at high frequencies. CONSTITUTION:As a means for connecting an electrode of a semiconductor laser 1 to transmission paths 51, 52, a metallic surface of a heat sink 2 is used to directly connect them, and a metallic wire is made unnecessary.

Filed: 1991-10-17
Abstract: PURPOSE:To control recording at a VTR so as to be stopped during a commercial (CM) in a stereo mode from the side of the television receiver by turning-on the infrared remote control signal for the stop/cancel of recording when the CM is inserted in the middle of a program, and photodetecting the signal at the VTR. CONSTITUTION:The remote control signal to stop/cancel the recording at a VTR 9 to be used is really photodetected by a so-called learning function and stored in a memory part 3. A microcomputer 6 for control monitors an audio multi-mode identification signal from a voice multiplexing circuit 7 built in the microcomputer, a timer 4 counts continuation time in a certain mode excepting for the stereo mode and when the mode is continued for more than fixed time, it is judged that the text of the program is in a monoral or double sound mode. When the mode is changed into the stereo mode in such a state, it is judged that this stereo mode shows the CM and when starting/ending the stereo mode, the above-mentioned remote control signal for the stop/cancel of recording is turned-on to the VTR 9. Thus, recording is stopped during the CM.
