Title: Supercooling degree control type expansion valve
Inventor: HIROTA HISATOSHI
IPC: F25B41/06
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To more increase a supercooling degree set value as a load becomes higher by sealing gas having a larger pressure change than that of a refrigerant to a temperature change in a sealed space of a power element. SOLUTION: As a refrigerant flowing in a refrigerant channel 2, HFC-134a is used, and as gas sealed in a power element chamber 12, ammonia is used. As to the pressure change to a temperature change, ammonia gas is larger than the HFC-134a. Accordingly, since a load of a refrigerating cycle is large, when a refrigerant temperature of an upstream side is raised, a pressure rise in the chamber 12 becomes larger than that in a refrigerant channel 2, and a valve disc 5 is moved in a closing direction. As a result, an amount of the refrigerant is reduced, and the degree of supercooling of the refrigerant of the upstream side is increased.  Contrarily, when a temperature of the refrigerant of the upstream side is lowered, a valve seat hole 4 is moved in an opening direction to increase a flow rate of the refrigerant, and hence the degree of the supercooling of the refrigerant of the upstream side is reduced.

Title: Surface light source device
Inventor: SHINOHARA MASAYUKI
IPC: F21V8/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To make the brightness distribution of a light emitting face uniform by setting the thickness of a light guide panel for a surface light source device to thicken at end part of the light incident face side, in the surface light source device which guides light emitted from a light source from a light incident face to the inside of the light guide panel and shuts the light inside the light guide panel and extracts the light outward from the light emitting face of the light guide panel. SOLUTION: In the surface light source device 21, light is made incident inside the light guide panel 22 from the light incident face 25, since a gap between the light incident face 25 and a reflection plate 32 can be removed, and there is no immediate light emission outward from an upper face of the light guide panel 22. Accordingly, the brightness at the end of the light incident face 25 side can be reduced, and the brightness of the surface light source device 21 can be improved. An incident angle on the light emitting face 23 can be made small by reflecting the light on a slope face 26, since an inclination is provided on the light incident face 25 side. Therefore, the light is made easy to be emitted from the light emitting face 23 till the light is emitted from the opposite end to the light incident face 25, and as a result, the brightness of the surface light source device 21 is improved.

Title: Gain control amplifier circuit
Inventor: HATASHITA HIROSHI
IPC: H03G3/30
Filed: 1985-02-06
Abstract: PURPOSE:To improve the disturbance characteristic and to stabilize the input impedance by using a bypass circuit so as to control a current of a PIN diode connected to the emitter thereby decreasing the current change in a transistor (TR) at gain attenuation. CONSTITUTION:The gain of a signal at an input terminal 1 is controlled by a gain control signal VAGC and outputted to an output terminal 2 from a collector of a TR1. When the gain is maximum, resistors 18, 19 are selected to turn off a TRQ2 almost, the emitter current of the TRQ1 flows to a constant current source I via a PIN diode D1 and a TRQ3 to minimize the impedance between the TRQ1 and common and to maximize the amplification factor. As the signal VAGC increases, the collector of the TRQ2 is increased and the current of the diode D1 is decreased, then the resistance between the emitter of the TRQ1 and common is increased and the amplification factor is decreased.

Title: Electronic device
Inventor: TAKAHASHI MASAHIRO
IPC: H05K7/20
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To improve heat transfer in fluid refrigerant, and making an electronic device suitable for highly heating characteristics caused by high density of electronic modules, by inserting a thin plate inside a cooling plate molded in an extrusion machine, separating inner ventilation paths, and making a short side of a ventilation path small. SOLUTION: An electronic device includes an electronic module 1, a cooling plate 2, and a thin plate 5. The thin plate 5 is inserted in the cooling plate 2 molded in an extrusion machine to separate the ventilation paths. Then, a short side of the path is made small and a thermal boundary layer is made thin, so a coefficient of heat transfer is made large. The heat condition is changed to one-side adiabatic condition, because there is no heat flux between the thin plate 5 and the refrigerant, but in this case an effect of improvement exceeds the demerit of the one-side adiabatic condition. When the thickness of the plate is increased, the flowing path is made thinner and the coefficient of heat transfer can be improved.
