Title: Heat pump
Inventor: ITO SADASUKE
IPC: F25B5/02
Filed: 1988-12-20
Abstract: PURPOSE:To improve an efficiency by a method wherein a plurality of evaporators in respect to a plurality of heat sources are connected in parallel in a refrigerant circuit, an expansion valve is arranged at an inlet of each of the evaporators, a refrigerant gas temperature sensing part is arranged at an outlet and then a refrigerant reverse flow preventing valve is arranged at least one outlet of the evaporator. CONSTITUTION:Refrigerant compressed by a compressor 1 and became an over-heated vapor of high temperature and high pressure is condensed by a condensor 2 and the refrigerant passes through a pipe 4. In case of a weak sun shine, the refrigerant passing through expansion valves 7 and 8 becomes an over-heated vapor by evaporators 9 and 11. As the sun shine becomes strong, a degree of over-heating of refrigerant in an evaporator 9 with a poor convection thermal conductivity is increased, so that a pressure of a thermo-sensitive cylinder 15 is increased, the expansion valve 7 is opened, a pressure within the evaporator 9 is increased and an evaporating temperature is increased. The evaporators 9 and 11 are connected to the pipe at their rear parts, so that a pressure within the evaporator 11 is also increased, a collected heat temperature is increased, an amount of collected heat under a convection is reduced and a degree of over-heating at an outlet of the evaporator 11 is reduced. The expansion valve is closed, and the refrigerant may not flow in the evaporator 11 by the check valve 22. Thus, the refrigerant may evaporate at a high temperature and a coefficient of result can be increased.

Abstract: PURPOSE:To make an electric connecting member by casting a high energy beam from the insulative layer side, removing partially the insulative layer and the base, filling with an electro-conducting material, and then removing the base. CONSTITUTION:A parent material 2 formed by putting a polyimide resin layer 2 on one side of a base 1 of Cu is irradiated with a beam 5 of eximer laser through a mask 4, and thereby holes 6 are formed in the insulative layer 2 while ones 7 are formed in base board 1. The number of pulses is controlled in accordance with the laser irradiation energy and the eroding speed into the base 1, and thereby the depth of the hole 7 is adjusted. Then Au plating is applied with this base 1 as a common electrode so as to fill holes 6, 7 with Au 8 to case protruding from the oversurface of the insulative layer 2, and thus an Au bump 9 is yielded. The base 1 of Cu is eroded selectively, and a connecting member 31 is obtained. If the dia. of hole 7 is widened by erosion within the extent greater than the dia. of the hole 7 and smaller than half the distance to the periphery of the adjacent hole, the conductive member 8 will become free from slipping off after removal of the base 1.
