Filed: 1986-09-05
Abstract: PURPOSE:To make the IC-implementation of a light quantity detecting circuit advantageous and to reduce the size and cost of the circuit by connecting at least two photodiodes which differ in spectral sensitivity reversely in parallel between input terminals of a differential amplifier. CONSTITUTION:The photodiodes 2 and 3 for short-wavelength and long- wavelength detection employ P-N junction diodes which have about 620 and 750nm peaks of spectral sensitivity among PN junctions on a silicon substrate. Then when light strikes on the diodes 2 and 3, photocurrents I2 and I3 are generated and the current (I2-I3) flows to a log diode 4 between the output terminal 1c of the differential amplifier 1 and a point P. The output V0 of the circuit is based upon a function of only the current (I2-I3) and the difference of this photocurrent is detected. Further, the diodes 2 and 3 are connected reversely in parallel, the diode 3 is arranged equally as many divisions, and the diode 2 is arranged surrounding the respective divisions across a substrate area, thereby reducing variance in the photodetection area ratio.

Title: Variable capacitance capacitor
Inventor: FUJII YASUO
IPC: H01G5/16
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To increase the variation rate of capacitance while enhancing the frequency stability and reducing the size by moving the variable part such that the average distance between a detection electrode and the movable part will be shorter than that between a drive electrode and the movable part while keeping balance between the Coulomb force and the resilience of working part. SOLUTION: When an external bias voltage is applied between a drive electrode 7 and a movable electrode 6, a Coulomb force is generated between them. A movable part 11 is attracted to the drive electrode 7 while keeping balance between its resilience and the Coulomb force. In this regard, the part of movable part 11 facing a detection electrode 8 moves more than the part facing the drive electrode 7. More specifically, the movable part 11 is displaced such that average distance between the movable part 11 and the detection electrode 8 will be shorter than that between the movable part 11 and the drive electrode 7.

Abstract: PURPOSE:To prolong the life of a device having many number of times of on and off of a power source by providing a control circuit for controlling a storage to a non-volatile memory according to information held in a memory circuit at the time of turning off the power source. CONSTITUTION:The outputs of flip flops 2, 5 are supplied to a NOR gate 4 to execute a NOR operation, form a power down pulse, it is supplied to a NAND gate 5 and a NAND operation with the output of the flip flop 1 is carried out. In such a case, the output of the NAND gate 5 is formed as a non-volatile memory storing signal, outputted to a memory circuit 6 and at the time of disconnecting the power source, the contents of a high speed volatile memory 7 are stored in an EEPROM8. At the time of turning on the power source, when the writing to the high speed volatile memory 7 is not executed, the flip flop 1 is not set, so that the output remains 0, and at the time of disconnecting the power source, even when the power down pulse signal is supplied to the NAND gate 5, a non-volatile memory storing signal is not formed and the rewriting of data to the EEPROM8 is suppressed. Thereby, the number of times of writing of the EEPROM is limited to a required minimum range and the service life of the device can be prolonged.

Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To suppress an increase of temperature rising time due to difficulty of warming a flange and nonuniformity of temperature and prevent a product from being coagulated by forming the flange supporting a reaction container of aluminum. SOLUTION: A heating route, e.g. an oil pooling hole 8, is provided inside flanges 2A and 2B for supporting both sides of a reaction container 1 and a heat insulating material 9 is provided outside the flange, and the flanges 2A and 2B are made of aluminum. When a film is formed on a substrate 4 to be treated, a silicon oil of 50-250 deg.C is circulated in the hole 8 and the flanges 2A and 2B are kept at a high temperature. At the same time, the heat radiation from the surface of the flange is prevented thanks to the material 9 provided outside flanges 2A and 2B, and the flanges 2A and 2B are easy to be warmed because the flange is made of aluminum. Therefore, the uniformity of temperature is improved, and the temperature rising time is short, so that a product generated by the reaction gas is hard to be coagulated.
