Title: Through anchor
Inventor: KOKETSU EIJI
IPC: B60R22/24
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a through anchor capable of preventing cracks from occur ring in a resin molded portion by dispersing residual stress caused by a heat shrink. SOLUTION: This through anchor 10 comprises a metal plate 12 and a resin molded portion 14 covering a periphery 23 thereof. Generally, residual stress caused by a heat shrink generated between the resin molded portion 14 and the metal plate 12 is high in the vicinity of the both ends in the boundary between the resin molded portion 14 and the metal plate 12 exposed therefrom. A notch 22 is formed in this position to expose one part of the periphery 23 of the metal plate 12 covered with the resin molded portion 14. Although the resin molded portion 14 thermally shrinks after molding of an insert, the shrink of the resin molded portion 14 is not subject to interference with the periphery 23 of the metal plate 12, since the periphery 23 of the metal plate 12 is exposed. As a result, cracks in the resin molded portion 14 at this portion can be prevented.

Title: Compressor capacity control device in freezing cycle
Inventor: MATSUOKA AKIO
IPC: F25B1/00
Filed: 1990-05-14
Abstract: PURPOSE:To reduce a frequent repetition of control of a compressor as much as possible, improve durability and controlling characteristic by a method wherein a deviation between a target operation amount and an actual operating amount is calculated and a comparison and discriminating means for outputting a target operating amount calculated only in the case that an absolute value of the deviation is more than a differential value to a control means is provided. CONSTITUTION:A differential value DELTA corresponding to a target number of revolution NcO of a compressor B is set. When an absolute value of deviation between the target number of revolution NcO calculated with an air blowing port temperature Ta being as a parameter and an actual number of revolution Nc is more than the differential value DELTA, a transmission ratio (epsilon) is varied in response to the target number of revolution NcO. In addition, since the differential value DELTA is continuously increased as the target number of revolution NcO is increased, so that at the time of high number revolution, a control repetition for the trans mission ratio can be reduced. Even in the case that a low number of revolution is set, since the differential value DELTA is already determined, even in the case the deviation between the target number of revolution NcO and the actual number of revolution Nc occurs, the transmis sion ratio control may not be carried out immediately. The repetition of control of the trans mission ratio can be reduced to a certain degree and its hunting can be prevented.
