Filed: 1980-09-08
Abstract: PURPOSE: To raise the volumetric and compressive efficiencies of a compressor, by preventing trasmission of heat to coolant gas in a compression space through the inner wall surface of the space.  
     CONSTITUTION: In a compressor 1, heat produced by mechanical friction at the bearing portions and sliding portions of a mechanical section B and heat of high- temperature lubricating oil are transmitted, via a cylinder 5, upper bearing 6 and lower bearing 7, to coolant gas introduced into an intake chamber 11 of a compression space and coolant gas being compressed in a compression chamber 12, so that the coolant gas is heated to some extent. However, according to the present invention, fluoroplastics 5B, 6B having a low heat conductivity is coated over the inner  wall surface 5A, 6A of the compression space 8 for minimizing heating of the  coolant gas. This also causes less increase in the specific volum of the coolant gas,  rise of the volumetric efficiency, and increase in the amount of coolant gas circulated in the coolant cycle, so that the efficiency of heat transfer can be raised. Further,s ince transmission of heat to the coolant gas in the compression chamber 12 is reduced, pressure rise of the coolant gas is lowered and therefore its compressive efficiency can be increased.

Title: Keyboard switch
Inventor: SASAKI TAKASHI
IPC: H01H13/14
Filed: 1991-05-29
Abstract: PURPOSE:To obtain a keyboard switch securing a sufficient stroke, and also having a thin type and feeling of high quality. CONSTITUTION:A key top 1 is made up of a hard member 1a for its top-face panel, and an elastic member 1b made of rubber or the like for its side-face panel. When the key top 1 is depressed, it is contacted at the elastic member 1b making its side-face panel to a housing 3. Since the side-face panel of the key top is made up of the elastic member, force repelled by the housing 3 is equally applied to the elastic member 1b making the side-face panel of the key top in a direction against the depressed direction of the key top. The elastic member 1b itself making the side-face panel of the key top is accordingly contracted, and accordingly the quantity of displacement by the contraction can be added as a stroke. This process can sufficiently secure the stroke of a keyboard switch, and therefore can have the effect of obtaining such a kind of keyboard switch that a key switch may be formed in a thick-wall type and accordingly a feeling of high quality in external appearance may be created even if the overall height of a keyboard is formed in thinness.
