Title: Catalyst for purifying exhaust gas of engine
Inventor: IHARA KAZUNORI
IPC: B01J23/63
Filed: 1989-12-27
Abstract: PURPOSE:To obtain a catalyst enhancing the purifying efficiency of a non- combustion component even when the temp. of exhaust gas is low by forming the first coat layer of alumina containing a catalytic component to the surface of a carrier at first before providing the second coat layer containing cerium oxide and an adsorbent thereto. CONSTITUTION:The first coat layer 12 based on alumina containing a catalytic component such as platinum or rhodium is provided to the surface of a honeycomb carrier 11 composed of e.g. cordierite at first. Next, the second coat layer 13 consisting of cerium oxide and an adsorbent such as a molecular sieve is formed on the first coat layer 12. Whereupon, when the temp. of exhaust gas is low, the non-combustion component in the exhaust gas is adsorbed on the adsorbent in the second coat layer and, when the temp. of the exhaust gas rises, the adsorbed component is desorbed from the adsorbent and diffused into the first coat layer to be purified. Therefore, purifying efficiency is enhanced.

Title: Controller for ac-dc converter
Inventor: TSUMENAGA MASAHIRO
IPC: H02M7/12
Filed: 1993-12-20
Abstract: PURPOSE:To make it possible to restrict a voltage during accident by permitting the operation of a converter during accident in an AC system by continuing the operation of an AC-DC converter when the line voltage does not rise even though a voltage to ground rises and stopping the operation of the converter when the line voltage also rises. CONSTITUTION:When a single-phase grounding accident occurs, the voltage to ground of AC voltage detectors 16 to 18, absolute value circuits 19 to 21 and a maximum value selection circuit (MS) 22 rises, and the level detector 23 becomes H. Also, the waveforms of the line voltage detectors 28 to 30, the absolute value circuits 31 to 33 and MS34 remain the same as normal state, and a level detector 36 remains as L. Therefore, in a converter protection circuit (CD) 25, the converter is operated by giving, for example, a command to operate with a firing angle a of 90 deg. to a firing angle controller 7. On the other hand, if an accident occurs in the same system and the rise of both the line voltage and the voltage to ground is detected, level detectors 23 and 35 become H. Because of this, CD 37 operate and a stop command is issued to the firing angle controller 7 and a pulse generator 14.

Title: Sample and hold circuit
Inventor: SATO TOSHIAKI
IPC: H03M1/12
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To suppress an error in hold voltage because of input voltage, by controlling the gate potentials of a first analog switch and a second analog switch of the same conduction type, which is driven with an opposite phase to the first analog switch, through a comparison of the hold voltage and a reference voltage. SOLUTION: At the sampling time, a first MOS transistor M1 is turned on to charge a hold capacity CH. At the hold time, since a pMOS transistor M5 is turned on and a pMOS transistor M6 is turned off if a hold voltage V is lower than output V1 of a constant voltage means, gate potential V2 of a second MOS transistor M2 shows a value obtained by dividing a source voltage VDD by resistors R2 and R3 . If the hold voltage is higher than the V1 , since the transistor M5 is turned off and the transistor M6 is turned on, the gate potential V2 is held at the source voltage VDD. Accordingly, an error due to influences of a capacity between a source and a drain of the second transistor M2 is decreased.
