Title: Power switching circuit
Inventor: HIASA KENZO
IPC: H02J9/06
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a power switching circuit equipped with a contact protective circuit where a countermeasure is applied so that the contact of a power switching relay may not fuse by rush currents during changeover of a power source. SOLUTION: In the case that a normal power source B1 goes off and that the power voltage supplied to load 3 is switched from the normal power source B1 to an auxiliary power source B2, the operation contacts R1 and R2 within a power switching relay 2 are opened, and then the exciting circuit 11b within a contact protective circuit 11 moves slowly to switch the power voltage supplied from the normal power source B1 over to the power voltage supplied from the auxiliary power source B2 and supply it to the load 3.  Accordingly, the rush current generated at switching from the normal power source B1 to the auxiliary power source B2 flows in condition that the recovery contacts R3 and R4 within the power switching relay 2 are closed, after passing the solid state relays SSR3 and SSR4 within the contact protective circuit 11, so the occurrence of trouble such as the abrasion, fusion, etc., of the recovery contacts R3 and R4 within the power switching relay 2 can be prevented.

Title: On-vehicle antenna
Inventor: SEKI KOICHI
IPC: H01Q1/32
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To house a GPS(global positioning system) antenna part and an antenna part for telephone in a small-sized antenna case. SOLUTION: A GPS antenna part 4 is housed in a GPS antenna housing part 3b formed on an elliptical metal base 3. An antenna part 5 for telephone consists of a linear element part and a circular crown part which is provided in the tip of the element part and is bent downward so as to be an umbrella shape. Because the crown part is bent downward, capacity produced between the metal base 3 operating as a ground plane and the crown part becomes large enough to make the diameter of the crown part small. Thus, it is possible to make the shape of the antenna part 5 for telephone small and to house the part 5 in an antenna case consisting of a cover 2 and the metal base 3.

Title: Control method for injection molding machine
Inventor: ISHIKAWA ATSUSHI
IPC: B29C45/70
Filed: 1993-10-01
Abstract: PURPOSE:To prevent the generation of defects such as sink marks and warping by utilizing distance sensing signals from a distance sensor and pressure sensing signals from a pressure sensor, and controlling a driving source. CONSTITUTION:A pressure control valve 42 is controlled in compliance with the distance L between platens sensed by a distance sensor 28 so that the initial distance between platens is retained as a target value by a microprocessing unit 43, and the mold clamping force P is varied according to the control of the value 42. Thus filling is carried out while the distance between platens is retained as the initial distance between the platens by varying the mold clamping force P. Then, as a mold is closed by the above arrangement, and a required minimum mold clamping force only is applied, gas generated by residual air and resin in the mold is exhausted easily. Also the initial distance between platens is set as the target value, and a parting face between a fixed mold and a movable mold is not opened even when the filling pressure of resin is applied thereon to eliminate the generation of flashes.
