Title: Cooling and heating device
Inventor: WATABIKI MASAMI
IPC: F25B29/00
Filed: 1989-02-14
Abstract: PURPOSE:To enable a simultaneous cooling and heating operation to be carried out and to perform an efficient generation by a method wherein each of indoor heat exchangers is branched and connected to a high pressure gas pipe and a low pressure gas pipe through a changing-over valve and it is connected to a liquid pipe through a refrigerant pressure reducer and a gas-liquid separator. CONSTITUTION:For example, in case that a cooling operation is carried out with an indoor unit 5b and a heating operation is carried out with indoor units 5a and 5c, a changing-over valve 9a of an outdoor heat exchanger 3 is closed, a changing-over valve 9b is opened, a changing-over valve 14b of an indoor unit 5b to be cooled is closed, a changing-over valve 15b is opened, changing-over valves 14a and 14c of the indoor units 5a and 5c to be heated are opened, and then changing-over valves 15a and 15c are closed. Refrigerant from a compressor 2 is distributed to the changing-over valves 14a and 14c, condensed and liquified at the indoor heat exchangers 6a and 6c. The liquified refrigerant passes through the refrigerant pressure reducers 16a and 16c and gas-liquid separators 17a and 17c, flows to a liquid pipe 13, a part of the liquid refrigerant is separated from the gas refrigerant, thereafter it is reduced in its pressure by the indoor heat exchanger 6b and the remaining liquid refrigerant is reduced in its pressure by an auxiliary refrigerant pressure reducer 20, then each of them is evaporated and gasified by an outdoor heat exchanger 3, it passes through the gas-liquid separator 4 and then it is sucked into the compressor 4.

Title: Combustion chamber of internal combustion engine
Inventor: YOKOYAMA JUNICHI
IPC: F02B23/08
Filed: 1989-02-14
Abstract: PURPOSE:To generate a powerful longitudinal swirl in a combustion chamber by setting an area of a conical surface forming a part of a combustion chamber wall to be larger at the side of an intake valve seat than that of an exhaust valve seat. CONSTITUTION:A top wall of a combustion chamber 18 at the side of a cylinder head 4 has each apex on valve stems 20, 21 centering on each intake valve seat and each exhaust valve seat, and it is formed with a part of conical surfaces 9, 10 extending in the almost tangential direction from the seating surface. Here an apex angle thetai of the conical surface 9 at the intake valve side is set to be larger than an apex angle thetae of the conical surface 10 at the exhaust valve side. With this constitution, intake air out of an intake port 5 flows into the combustion chamber 18 when an intake valve is opened, and since the main flow is guided along the conical surface 9, it smoothly flows in the combustion chamber without producing any swirl. Then, the main flow of the intake air is guided to the conical surface 9 with a large area without being damped, thereby going round in the underside direction of an exhaust valve. Therefore a powerful longitudinal swirl comes to be generated in the combustion chamber 18.

Title: Clutch release bearing
Inventor: MORI YUUJI
IPC: F16D23/14
Filed: 1981-03-12
Abstract: PURPOSE: To prevent generation of heat and abnormal wear by aligning the rotation axes of a bearing and diaphragm spring through self-centering of the bearing with regard to a sleeve.  
     CONSTITUTION: A self-lubricating friction plate 11 made of synthetic resin is attached to a surface facing an outer supporting cover 2 of fork bearing flange 10 fixed to a sleeve 9. Adjacent to the friction plate 11, a free ring 13 with a slant or spherical surface 12 is put with a gap on the external surface, transferable in the radial direction. The cover 2 has a flange 15, its external taper 16 being in contact with the spherical face 12 and pressed through the free ring 13 to the flange 10 by means of a flat spring 18 which is positioned by a stop ring 17. As the rotational axis of the sleeve 9 is eccentric to that of a diaphragm, the free ring 13 is radially shifted along the plate 11 to eliminate the eccentricity. As both axes are slanted, the flange 15 slides on the spherical face 12 to keep them self-aligned.
