Title: Selective optical receiver circuit
Inventor: NAKAMURA KEIJI
IPC: H04J14/02
Filed: 1992-08-26
Abstract: PURPOSE:To reduce cost or power consumption by eliminating necessity for using the amplifier or device of a wide frequency band characteristic or low distortion when a transmission channel is increased. CONSTITUTION:When an optical FDM signal with frequency multiplexed arbitrary (n) channels is photodetected, a photodetector 1 converts this optical FDM signal into an electric signal and outputs it. A dual gate FET 2 is composed of a mixer circuit, the output of the photodetector 1 is inputted to the first gate, and the output of a local oscillator 5 is inputted to the second gate. When the output of the photodetector 1 and the output of the local oscillator 5 are respectively inputted to the first and second gates, frequencies f1-fn of desired channels 1-n are selected and converted to a desired frequency band fs by the dual gate FET 2. In the prescribed frequency band fs from the dual gate FET 2, only the central frequency band is selected and outputted to a main amplifier circuit 4 by a band pass filter 3. This central frequency band is amplified and outputted by the main amplifier circuit 4.

Title: Proximity sensor
Inventor: KAWASHIMA KAZUNORI
IPC: H01H36/00
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a proximity sensor which can be miniaturized in a simple circuit constitution. SOLUTION: When a metal to be detected gets closer to a detecting coil L1, an induced current flows from the coil L1 to the metal to be detected, and loss of energy is generated at the detecting coil L1. When this loss becomes larger than energy compensated by an emitter follower 2, oscillation of a oscillation circuit stops, a collector current at Tr2 is decreased, and Tr1 turns off to decrease a consumed current as the whole circuit through a point C. In the case where the metal to be detected is not close to the detecting coil L1, energy is compensated by the emitter follower 2, the oscillation circuit makes oscillation, and the consumed current as the whole circuit through the point C is increased.

Abstract: PURPOSE:To decrease the hardward amount of the titled circuit by using a code bit of input/output data of an operating circuit to detect the overflow of the result of operation and correction of its output data. CONSTITUTION:Signals Ain, Bin are inputted to an adder circuit 401 and the result of operation Cout is obtained. Since a handled signal is represented by 2's complement, and when the MSB is at L, the signal is a positive number and when at H, the signal is a negative number, then a selector signal 403 of a data selector 402 is formed as shown in the figure. In case of overflow, an overflow detection signal is generated and required data is selected at the same time. That is, when both P, N are at L, the selector 402 selects the operation result Cout. On the other hand, when the P of the signal 403 is at L and the N is at H, black clip data B is selected, and when the P is at H and the N is at L, white clip data W is selected. Through the circuit constitution above, since no magnitude comparator is used, the number of components is decreased.
