Title: Oven tray
Inventor: GOKAJIYA YOSHIYUKI
IPC: F24C15/16
Filed: 1987-03-17
Abstract: PURPOSE:To prevent thermal deformation of an oven tray caused by thermal strain at the time of cooking and make the finished thickness of foodstuffs uniform by forming a rectangular pressed part with taper ridge part at the bottom of the oven tray. CONSTITUTION:A rectangular pressed part 2 is formed at the bottom of a square oven tray 1, that is, symmetric taper parts 5 are formed from a rectangular part 3 having a flat part 4 at the center to the periphery 8 at the bottom part and taper ridge parts 6 are formed toward each corner. As a result, since thermal stress acts to the periphery 8 of the oven tray 1 and each corner part in well-balanced condition, the thermal deformation of the oven tray can be prevented. Further, the press depth of the tray made shallower relatively (for instance, 1.0-1.5mm) can prevent the finished thickness of foodstuffs from changing or unfavorable points in cooking caused by inclination of the cooking plate from occurring.

Title: Rotary compressor
Inventor: SUDO MASAYASU
IPC: F04C18/356
Filed: 1989-03-16
Abstract: PURPOSE:To prevent interference noise to be generated by a delivery gas and the oil in a delivery chamber to reduce noise during operation by forming an oil delivery path by means of a noise eliminating chamber cover, in which an oil drain hole is drilled, under a noise eliminating chamber and the secondary throttle section, connected to the oil drain hole, in the oil path cover. CONSTITUTION:The oil delivered from a cylinder through a delivery valve 8 enters the secondary throttle groove 19 in an oil path cover plate 17 from an oil drain hole 21 facing a delivery valve chamber 15, pushed by delivery gas pressure, and released out of the top of the groove 19. Since the groove 19 is a fine groove throttle, its function cannot be almost affected by the noise radiated from the delivery valve chamber 15. Even if the oil filled in the cylinder 3 when a rotary compressor is stopped or the oil circulating during operation is delivered, the oil will not remain in the delivery valve chamber 15 under a delivery noise-eliminating chamber 11. The oil is released rapidly through the oil drain hole 21 to the top of the groove 19 to prevent the oil from being remaining in the delivery valve chamber 15. Thus, interference noise to be generated by the delivery gas and the oil in the delivery valve chamber 15 can be prevented, and a quiet rotary compressor can be obtained.
