Title: Manufacture of thermosetting resin laminated sheet
Inventor: OGATA MASARU
IPC: B29B15/12
Filed: 1989-08-31
Abstract: PURPOSE:To suppress a dimensional change to a small degree by heat-treating a prepreg in a tension-free state at temp. equal to or higher than the softening point of a resin. CONSTITUTION:In a method wherein a prepreg is prepared while a long sheet like base material is transferred, tensile stress is always applied to the base material during a manufacturing process. Since impregnation, drying and cooling are performed in this state, tensile residual stress is present in the prepared prepreg. This residual stress is further amplified at the time of lamination and molding to allow large residual stress to be present in a molded laminated sheet. Therefore, contrarily, when the prepreg is heat treated in a tension-free state at temp. equal to or higher than the softening point of a resin before lamination and molding to preliminarily remove the residual stress in the prepreg, the residual stress of the laminated sheet after lamination is reduced and a dimensional change can be suppressed.

Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To improve the operating efficiency of a refrigeration cycle device by a method wherein a condenser is constituted so as to effect counterflow heat exchange and a refrigerant side flow passage is formed so that the number of outlet paths of refrigerant, which flows from a compressor into the condenser, becomes smaller than the number of inlet paths while mixed refrigerant is sealed into the refrigeration cycle device SOLUTION: During cooling operation, gas refrigerant, compressed by a scroll compressor 1 so as to have a high temperature and a high pressure, is introduced into an outdoor heat exchanger 3 through a four-way valve 2. In this case, the heat exchange of the gas refrigerant is effected with outdoor air through counterflow heat exchange while the refrigerant, branched into a larger number of inlet paths is being joined together into a smaller number of outlet paths, whereby the gas refrigerant dissipates heat and is condensed into liquid refrigerant. Further, the refrigerant, changed into liquid state by the condensing in the outdoor heat exchanger 3, is reduced in pressure in a throttling device 4 and, thereafter, is introduced into an indoor heat exchanger 5.  The heat exchange of the refrigerant is effected in the indoor heat exchanger 5 with indoor air through parallel flow heat exchange while the refrigerant, branched into the smaller number of the inlet paths is being joined into the larger number of the outlet paths, whereby the refrigerant absorbs heat and is evaporated into the gas refrigerant.
