Title: Method for fixing motor
Inventor: FURUTA YOSHIHISA
IPC: H05K7/20
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To obtain a motor fixing method which makes it possible to efficiently restrain the temperature rise of a motor without causing the enlargement of a device in size and weight or an additional heating source and hardly causes problems such as output drop due to temperature rise and seizing-up so that the motor can be placed closer to an IC circuit and electric appliances can be made more compact. SOLUTION: A box 1 containing a motor 11 is adhered to a radiative supporting plate 3 via a thermal conductive adhesive layer 2. This structure enables the motor containing box to be easily brought into contact with the radiative supporting plate via the thermal conductive adhesive layer 2, making it possible for the accumulated heat of a motor to be efficiently conducted for heat radiation to the supporting plate via the thermal conductive adhesive layer. Furthermore, the efficiency in manufacturing the device is good because simple work by compression-bonding requires no curing time and a convenient part of the motor can be used as an arbitrary area to be adhered, and the vibration of the motor is hardly transmitted to outside because the adhesive layer absorbs the vibration.

Title: Freezing system with double vaporizer for domestic refrigerator
Inventor: HEINZU JIYASUTAA
IPC: F25B1/10
Filed: 1989-12-12
Abstract: PURPOSE: To raise the heat efficiency, by constituting the freezing system such that a phase separator connects the second evaporator to the first expansion valve in refrigerant flow relation, and that it gives intermediate cooling to the section between first compressor and the second compressor. CONSTITUTION: Vapor-phase refrigerant compressed with a compressor 15 is mixed with a vapor-phase refrigerant at saturation temperature from a vapor-phase separator 27, and further it is compressed with a compressor 17 and becomes a vapor-phase refrigerant at high temperature and high pressure, and then, it is condensed within a condenser 21. Next, the condensed vapor-phase refrigerant passes an expansion valve 23, and expands from high pressure to middle pressure lower than that within an evaporator 25. This refrigerant in liquid phase and vapor phase enters the phase separator 27, and the liquid-phase refrigerant is accumulated at the bottom of a container, and the vapor-phase refrigerant is accumulated at the upper part. Mixing the vapor-phase section of this refrigerant with the vapor-phase refrigerant having come out of the compressor 15 will cool the vapor-phase refrigerant having come out of the compressor 15, since the temperature of the vapor-phase refrigerant from the phase separator is about -3.9 deg.C, and the temperature of the gas refrigerant at the inlet of the compressor 17 becomes low. On the other hand, the liquid-phase section within two-phase mixed refrigerant from the evaporator 25 flows, passing through the expansion valve 11 from the phase separator 27, and the pressure of the refrigerant drops. This residual liquid- phase evaporates within the evaporator 13, and cools the evaporator 13.
