Filed: 1990-06-13
Abstract: PURPOSE:To permit the refrigerating oil separated from an oil separator to be returned properly to a compressor in order to reduce a lowering in refrigerating performance by a method wherein the opening degree of a flow amount adjusting valve provided in an oil passage for returning the refrigerating oil separated from the separator to a compressor is controlled according to the time of the continued operation of the compressor after the start of its operation. CONSTITUTION:Voltage E1 is delivered from a device 18 for controlling a flow amount adjusting valve after the lapse of time (t) during which the discharged amount of refrigerating oil from a compressor 1 is small. By this voltage E1, the coil part 17a of a flow amount adjusting valve 17 is energized to make small the opening degree of the flow amount adjusting valve 17. Since the amount of the refrigerating oil being sent back into the compressor 1 through an oil passage 8 is reduced as the opening degree of the flow amount adjusting valve 17 is decreased and since the amount of the refrigerating oil discharged from the compressor 1 together with a gas refrigerant is also small, a predetermined amount of the refrigerating oil is retained in the compressor 1. Therefore, a full lubrication is effected, the amount of the gas refrigerant being sent back into the compressor 1 through the oil passage 8 becomes small and a lowering in the refrigerating performance of a refrigeration device is reduced.

Title: Chair with decorative accessory
Inventor: FUJIMOTO KAZUO
IPC: A47B95/04
Filed: 1990-06-13
Abstract: PURPOSE:To attach decorative accessories on a chair in an action and allow anyone to easily replace an unholstered sheet of the chair by a method wherein stopper pins each having a small diameter are put into slits and stopper parts are caught by the edges of the slits. CONSTITUTION:When pushed into through-holes 32, stopper pins 22 are bent inward because they are guided by stopper parts 30. When the stopper parts 30 are penetrated through the through-holes 32 until the shoulders of the stopper parts 30 are projected beyond the bottom face of the through holes 32, the stopper pins 22 are ready to get into slits 34 and slip into the slits 34 due to the outward restoring force of the stopper pin 22. When a decorative accessory is attached, the stopper parts 30 are only put into guide holes 36 and pushed down, so that the decorative accessory is fixed due to the elastic force of the stopper pins 22. Therefore, the decorative accessory can be attached in one action. When an upholstered sheet 14 is taken off, the stopper parts 30 which are projected from a structural member 18 are held together and pushed inward and a stopper plate 10 is pulled upward, so that the stopper parts 30 are easily pulled off.
