Title: Load driving circuit
Inventor: KINOSHITA HITOSHI
IPC: H02P7/288
Filed: 1990-05-25
Abstract: PURPOSE:To prevent the number of external components from being increased by controlling a through-current prevention control transistor (TR) connected between an emitter and the base of one output TR driving TR turned ON from OFF at load current switching to be in the OFF state from the ON state. CONSTITUTION:A PNP through-current prevention control TR QP3 connected between the emitter and the base of one output TR driving TR QP1 turned ON from OFF at load current switching is controlled to be in the OFF state from the ON state. Thus, the inversion of the TR QP1 turned ON from OFF is delayed by a delay till the TR QP3 reaches the OFF from the ON state. Thus, even when the inversion of the other TR QP2 turned off from the ON state at the load current switching is delayed, simultaneous ON state of two output TRs in each push-pull circuit is prevented. Thus, the increase of the number of externally mounted components is prevented.

Abstract: PURPOSE:To make it possible to form a fine connecting hole exceeding the resolution limit of lithography technology by forming the connecting hole, wherein the side wall is formed on the sidewall of a hole pattern, which is formed with a resist film as a mask. CONSTITUTION:A resist film 14 is formed on the upper surface of an insulating layer 13 on a conductor layer 12 formed on a water 1. An opening part 15 is formed in the resist film 14. Then, a hole pattern 16 is formed in the insulating layer 13 by using the resist film 14 so that the insulating layer 13 remains in the thin film state on the upper surface of the conductor layer 12. Thereafter, the resist film 14 is removed, and a side-wall forming layer 17 having a specified thickness is formed on the upper surface of the insulating layer 13. Then a side wall 18 is formed on the sidewall of the hole pattern 16 with the side-wall forming layer 17. The side wall 18 is used as an etching mask, and the insulating layer 13 at the bottom part of the hole pattern 16 undergoes anisortropic etching until the conductor layer 12 is exposed. A connecting hole 19 is formed in the insulating layer 13. Therefore, the opening width of the connecting hole 19 is formed so that the width is smaller by the thickness of the film of the side wall 18.

Title: Noise filter
Inventor: NINOMIYA KOJI
IPC: H01F37/00
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a noise filter in which noise removing capability is made satisfactory, and yield becomes satisfactory. SOLUTION: Plural individually formed divided magnetic bodies 40 are arranged through a core holder 42 inside a case part 11 and a case part 12 whose one face is opened. A wire groove 22 is formed on the joint faces of the divided magnetic bodies 40, and a wire 30 is arranged in a space formed in the wire groove 22. The divided magnetic body 40 is made shorter than magnetic body in a conventional noise filter, and even if the joint faces are inclined at the same angle, the difference in thickness at the both edge is made small. Therefore, even if the joint faces of the faced divided magnetic bodies 40 are jointed closely, the dimension of a hole part constituted of the mutual wire grooves 22 of the faced divided magnetic bodies 40 can be made large enough for the wire to be inserted.  As a result, for example, even when the inclined divided magnetic bodies 40 are used, a closed magnetic path can be ensured in the surrounding of the wire, and the noise elimination of the wire can be attained satisfactorily.

Title: Height control method of rolling stock floor surface in stopping at station
Inventor: KOIZUMI TOMOSHI
IPC: B61F5/10
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To quickly and surely minimize the difference in level between a platform and a rolling stock floor surface by measuring the time of exhausting from an air spring when the rolling stock stops at a station, and stopping the exhaust when a prescribed time passes. SOLUTION: In order to moderate the difference in level between a platform and the floor surface of a body, the exhausting time of an air spring 3 is set to a prescribed drop of the body by an exhausting timer 11d, and the feeding time to the air spring 3 is set to a prescribed rise portion of the body by a feeding timer 113, and a minute regulation is performed by an automatic height regulating mechanism 8. Therefore, the raising and lowering control of the body can be surely performed. Since the exhausting time from the air spring is measured, and it is judged that the body is lowered to a prescribed height after the lapse of a prescribed time to stop the exhausting, detection and judgment of the mechanical operating quantity are dispensed with to eliminate the body lowering position slippage.  Further, since exhausting of a large flow rate can be performed, the exhausting control of the air spring can be quickly performed, the height of the vehicle floor height can be precisely controlled.
