Patent JP-H01318413-A (JP)
Title: Semiconductor circuit and signal processing system using the same circuit
Inventor: KODERA NOBUO
IPC: H03F3/347
Filed: 1988-06-20
Abstract: PURPOSE:To reduce the change of the electrical characteristics against the change of the threshold voltage of an FET by securing the parallel connection between the drain-source current path of a 1st FET having the short circuit connection secured between the gate and the drain and the drain-source current path of another FET having the same short circuit connection as the 1st FET. CONSTITUTION:The gate-source voltage V1 of a 1st FETQ11 is dependent on the input current I1 and the threshold voltage Vth owing to the parallel connection secured between the FETQ11 and another FETQ12. The voltage-current characteristics of the parallel connection secured between the FETQ11 and Q12 are matched with the voltage-current characteristics of a 2nd FETQ2 which has the same voltage Vth and works in a saturated area. Therefore the current flowing to the drain-source current path of the FETQ2, i.e., the output current I2 of a current mirror circuit is equal to the input current I1. The current I2 is decided by the current I1 and a constant K and free from the change of the voltage Vth.

Title: Exhaust gas filter
Inventor: SHIMODA HISANORI
IPC: F02B3/06
Filed: 1986-06-26
Abstract: PURPOSE:To burn and regenerate an exhaust gas filter in uniform temp. distribution by making the inner diameter of an inlet side of exhaust gas larger than the inner diameter of an outlet side thereof and making the passage of exhaust gas a tapered shape in the respective cells of a honeycomb structural form. CONSTITUTION:An exhaust gas filter 1 is constituted by alternately providing closed parts 4, 5 in the end parts of the cells of a honeycomb structural form formed with plural cells 2 by porous ceramic. Further the inner diameter of an inlet side of exhaust gas is made larger than the inner diameter of an outlet side thereof and passages 6, 7 of exhaust gas are made to a tapered shape. Therefore in case of collecting soot 8 incorporated in exhaust gas of a diesel engine, the areas of the cell walls 3 of the downstream side are decreased and the amount of soot to be deposited is decreased. As a result, at a time for burning and regenerating the exhaust gas filter 1, the quantity of heat generated by the combustion of soot in the downstream side is made little and thereby the excessive temp. elevation in the downstream side can be prevented.

Title: Manufacture of color-separating filter
Inventor: YANO KOUSAKU
IPC: G02B5/20
Filed: 1979-11-19
Abstract: PURPOSE: To obtain a color-separating filter free of a breakaway with good reproducibility by vapor-depositing Zn x Cd 1-x S (0≤X≤1) at a specific vapor-deposition source temperature in stripes while holding a substrate for filter formation within a specific temperature range.  
     CONSTITUTION: While the substrate for filter formation is kept at 70W200°C, a solid solution of 20mol% ZnS and 80mol% CdS is used as a vapor-deposition source and its temperature is set to 700W1,000°C so as to form a vapor-deposited film of Zn x Cd 1-x S (0≤X≤1) composition on the surface of the substrate. Under those temperature conditions, the adhesion between the substrate and filter is high and the film with a proper ZnS-to-CdS mol ratio is formed. Next, the vapor-deposited film is photoetched in stripes. In this case, the occurrence of a breakaway between the vapor-deposited film and substrate is eliminated. Thus, the color-separating filter of 450W500nm in absorption terminal wavelength is manufactured with good reproducibility.

Title: Sense amplifier circuit
Inventor: ARAI KOJI
IPC: G11C11/41
Filed: 1992-05-18
Abstract: PURPOSE:To provide a sense amplifier circuit which is reducible in power consumption by suppressing the through current of a CMOS static RAM at the time of sensing operation. CONSTITUTION:When a precharge signal c1 to a potential VDD again and precharging operation is started, a BIT line b1 which falls to a GND potential is precharged up to the potential VDD. In this case, a PMOS FET p1 turns OFF first and an NMOS FET n3 turns ON as the potential of the BIT line b1 gradually rises, so that the potential of a sense amplifier inversion output s2 is precharged to the GND potential. In this case, a sense amplifier output s1 is still at the GND potential. Almost no through current flows to the sense amplifier even in precharging operation like this.
