Title: Semiconductor photodetector
Inventor: KONAKANO HIROSHI
IPC: H04N5/374
Filed: 1987-12-21
Abstract: PURPOSE:To reduce the load capacitance of a photoelectric transducer and to obtain a dynamic range extensively by incorporating a source follower circuit. CONSTITUTION:Transmission gates 2 receive a signal from a shift register 3 and are turned ON sequentially, and the output signal of each photoelectric transducer is transferred to a Vsig line 8. The voltage of the Vsig line 6 is inputted to the source follower circuit 4. The output signal of a semiconductor photodetector is detected at a Vout terminal 7, however, its output voltage follows up the input voltage-output voltage characteristic of the source follower circuit. Thus, by performing the voltage conversion of the output signal of the photodetector by the source follower circuit, the load capacitance of the photodetector can be reduced, and a high output signal can be obtained from the photodetector, and furthermore, the wide dynamic range can be secured by correcting an output characteristic by the source follower circuit.

Abstract: PROBLEM TO BE SOLVED: To prevent an effect due to dispersion in a basic oscillated wavelength of a semiconductor laser by forming plural optical waveguides on an optical wavelength conversion element, changing the widths, the polarization inversion periods of the optical waveguides and changing a phase matching wavelength. SOLUTION: Plural optical waveguides 10 are formed on a sheet of optical wavelength conversion element 11, and the widths, polarization inversion periods of respective optical waveguides 10 are changed, and the phase matching wavelength is changed.

Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a video recording controller capable of automatically completing the video recording of a broadcast program without inputting a video recording completing time or a video recording time. SOLUTION: When a switch 1 operated during the video recording of the broadcast program, a memory 17 stores the voice broadcast system of the program to be outputted by a broadcast system detecting circuit 16.
