Title: Detecting circuit of reference voltage
Inventor: SHINCHI OSAMU
IPC: G05F3/24
Filed: 1982-12-28
Abstract: PURPOSE:To detect reference voltage including earth voltage stably and highly accurately by using a pair of voltage dividing circuits practically having the same constitution as an input circuit and a reference voltage circuit. CONSTITUTION:When input voltage VIN crosses zero voltage from negative to possitive voltage, the impedance of depression IGFETQ2 in an input circuit 1 is reduced lower than that of a depression IGFETQ4 in a reference voltage circuit 2, the output level of an enhancement FETQ12 is increased and the output level of an enhancement FETQ14 is reduced. Consequently, an FETQ12 in an output buffer circuit 4 is turned on, an FETQ17 is turned off, an FETQ19 is turned on, and output voltage VOUT is reduced from the high level to the low level close to VSS=0V, so that the earth voltage can be detected highly accurately even at a crossing moment.

Abstract: PURPOSE:To reduce influence of convection caused by gravity of gas within a clearance in a freezer in which discharged gas is fed into a closed chamber having a variable capacity through movement of a movable member within a cylinder and expanded there by a method wherein a size of clearance between the cylinder and the movable member is specified. CONSTITUTION:High pressure gas such as herium compressed by a compressor 17 passes through a gas suction valve 18, flows into the first closed chamber 6 in an expansion unit 11, then passes through a gas passage 3a formed in a movable member 3 and is fed into a cold accumulator 5, where the gas is cooled by cold accumulated within a cold accumulation device 5 under previous cycle. The cooled gas is fed into the second closed chamber 7 through a gas passage 3b, where the gas is expanded to generate cold. The cooled gas passes through the gas passage 3b into the second closed chamber 7, where the gas is expanded to produce cold and the item to be cooled is cooled. In this case, a size (d) of the clearance between an inner circumferential surface of the cylinder 2 and an outer circumferential surface of the movable member 3 is set to satisfy a relation of 1/1000<=d/D<=1/100 in respect to an inner diameter D of the cylinder 2.

IPC: F24F13/22
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent flying of water through the air outlet opening of an air- conditioner and to prevent the occurrence of air channeling to a heat-exchanger by a method wherein a resin composition containing crystalline polyorefin and an inorganic filler is used as a material for a spacer inserted in the bent part of a heat-exchanger. SOLUTION: A spacer 8 is inserted and arranged in a gap 7 of a bent part 6 of a C-shaped evaporater (a heat-exchanger) 2. One of the necessary component of a material for the spacer 8 is crystalline polyorefin. When crystalline polyorefin is used, since a friction factor is low, the fin of the evaporater 2 is not damaged. Further, since strength is high, the spacer 8 itself is not broken, and the spacer is easily and smoothly inserted in the gap 7 of the bent part 6. It is preferable that crystalline polypropylene is sued as crystalline polyorefin. A granular filler, such as talc and clay, a scale-form filler, such as mica and graphite, a hollow filler, such as pumice, and fibers, such as glass fibers, are numerated as an inorganic filler.
