Title: Switching power unit
Inventor: MATSUO YASUSHI
IPC: H02M3/00
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To surely prevent overvoltage from being applied to a load, by short- circuiting across terminals and maintaining the short-circuit condition in the case where overvoltage is applied between the terminals. SOLUTION: This switching power unit has a load short circuit detection control circuit 3, which detects a short-circuit between a load overcurrent limiting circuit 2 and a load terminal 6 to interrupt a collector current of a main switching transistor circuit 1 upon load short-circuit, and a Zener diode 8 which absorbs and limits overvoltage applied across a power supply terminal 7 and the load terminal 6. When voltage across the load terminal 6 reaches a Zener voltage value, a resistance value in a yield region inside the Zener diode 8 decreases, so that an over current flows, breaking is instantaneously caused almost without self heating, and a short-circuit condition is generated. In this way, by setting a Zener voltage value of the Zener diode 8 at an overvoltage value or below against a load, applying of the over voltage to the load can be surely avoided.

Title: Capacity control structure for variable capacity compressor of single side piston type
Inventor: KAWAGUCHI MASAHIRO
IPC: F04B27/08
Filed: 1993-04-28
Abstract: PURPOSE:To hinder the discharge capacity from increasing above the capacity appropriate for the cooling load and prevent producing of frost in an evaporator by operating a pressure release control valve in the direction of closing a pressure releasing passage in association with a drop of the differential pressure between he discharge pressure and suction pressure. CONSTITUTION:A pressure release control valve 36 to make the pressure release control in compliance with the differential pressure between the discharge pressure and suction pressure is installed in a pressure release passage 1b which is to connect a crank chamber 2a with the suction pressure region 3a. The valve 36 is operated in the direction of closing the pressure release passage 1b in association with a drop of the differential pressure. When the differential pressure sinks, the degree of opening of the valve 36 lessens, and the amount of outflowing refrigerant from the crank chamber 2a is suppressed. There is no risk of widening of the pressure drop in the crank chamber 2a due to this suppression of the outflowing amount. Because the pressure in the crank chamber does not sink to any larger extent, there is no risk of enlargement of the swash plate inclining angle, and no frost will be produced which is likely around the ice point.

CONSTITUTION:The condensing distance of the Fresnel lens B constituting the screen of the rear projection television is set larger on the periphery than at the center and the offset quantity of the lenses on the front and rear surfaces of the lenticular sheet A is changed so as to have at least >=1 inflection points in the graph of the change rate thereof. Namely, the Fresnel lens B is formed to have multifocuses and the condensing distance in the peripheral part is set longer than at the center to adjust the incident angle on the lenticular sheet A. The offset quantity of the lenses 1, 2 on both surfaces of the lenticular sheet A is set at the offset quantity shown in the graph C having the two inflection points from the center to the periphery. The exit light from the Fresnel lens B can prevent the unequal colors arising from the loss of the color balance by a difference of the projected light from red and blue projecting tubes in the incident angle on the Fresnel lens B in this way.

The enzyme liquid is added with a ketone compound (e.g. 4- chloroaceto-acetic acid ethyl ester) of an amount corresponding to 10-1,000 times the weight of the enzyme and with a reduced nicotinamide adenine dinucleotide of an amount equimolar to the ketone compound used as a raw material and optionally Tween 80, etc., and the components are made to react at 15-40 deg.C for 1hr-7 days under agitation. The progress of the reaction is traced by gas chromatography and the reaction is terminated when the raw material is disappeared. The obtained reaction liquid is subjected to centrifugal separation, extraction and purification to recover an optically active alcohol.
