Title: Variable duty type pulse drive device
Inventor: OKADA KAZUYOSHI
IPC: H02M3/155
Filed: 1982-11-30
Abstract: PURPOSE:To eliminate a noise by coupling a controller and a drive unit through a series signal transmission line and passing a digitally encoded dury control signal for deciding a duty ratio of a drive pulse train to the series signal line. CONSTITUTION:A controller 6 and a drive unit 7 are coupled through a series signal transmission line 5. The controller 6 calculates to decide a duty ratio of a drive pulse to be applied to a transistor 8 under the prescribed input conditions, with the result that it produces a duty control signal for specifying one stage of 16 duty ratios represented by 4-bit binary numbers. This control signal is transmitted to the drive unit 7, and latched to a latch circuit 11 through a series/parallel converter 10. The latched parallel data are inputted to a counter 14, a drive pulse train of the prescribed period is formed at the duty ratio corresponding to the parallel data, and applied to the gate of a MOS transistor 8.

Title: Manufacture of compressor for refrigerator
Inventor: JINGU NAOKI
IPC: F04D29/60
Filed: 1990-08-10
Abstract: PURPOSE:To remove a defect such as corroding an iron system part in the inside so as to improve durability by using the first oil of low water absorptivity in an assembly process to be extracted in the final process of assembly, and then injecting the second oil of high water absorptivity to be sealed. CONSTITUTION:When an assembly process is also advanced to approach the final, works of assembly and adjustment are advanced while immersing an assembly product in oil injected into the inside of a housing. As the first oil used in the case of this assembly, oil of ester system, having low water absorptivity and compatibility with the second oil, is used. The second oil is placed in a very good correlation to a refrigerant in the point of solubility or the like but provided with high water absorptivity. Consequently, contact with the outside air for a long period is not preferable. Then, the first oil in the inside of the housing is extracted after completion of the final assembly of a compressor, thereafter the second oil is injected to immediately seal the housing, so that it copes with the high water absorptivity of the second oil.

Filed: 1987-08-26
Abstract: PURPOSE:To obtain a potentiometer, a resolver, a synchronizer, etc., by detecting voltage variation or current variation by a pickup coil which moves on the outer circumferential surface of a rod body which has specified length and many short-circuit coils. CONSTITUTION:The movement detector consists of the rod body 1 with the specific length, a short-circuit coil group 4 consisting of (n) short-circuit coils 3 which are arranged independently in the length direction of the rod body 1, and a pickup coil part 9 which is provided movably on the side of the outer circumferential surface 1a of the rod body 1. When a constant voltage is applied to the exciting coil 9a of the coil part 9, the coil 9a and the coil group 4 produce main magnetic flux phiP to supply a current to the coil group 4, thereby producing short-circuit coil magnetic flux phiS in such a direction that the main magnetic flux phiP is canceled. Then a coil 9b generates a specific voltage to move the coil part 9 in the axial direction (x), thereby obtaining a voltage variation output when the coils 9a and 9b are used or a current variation output when only the coil 9a is used.
