Title: Constant voltage power supply unit
Inventor: KOYASU TAKAHISA
IPC: G05F1/56
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To simplify constitution and to reduce terminals for connection in a power supply unit provided with the circuits of two systems for supplying different voltages in accordance with the on/off states of a switch. SOLUTION: When an ignition switch IG is turned off, an operand amplifier OP2 drives a control transistor Tr4 and controls the base current of an output transistor Tr2 so that power voltage VOS supplied to ECU becomes second voltage V2 for standby. When the ignition switch IG is turned on, an operand amplifier OP 1 drives a control transistor Tr3 and the base current of a control transistor Tr1 is controlled so that power voltage VOS supplied to ECU becomes first voltage V1 for operation (V1>V2). Since the control transistors Tr3 and Tr4 selectively operate, the base current route of the transistors Tr3 and Tr4 is made to be common and one capacitor for phase compensation CO connected to the route is given. Consequently, circuit constitution can be simplified and terminals installed in power IC 10 can be reduced.

Title: Drain port lid
Inventor: OKAMOTO KOICHIRO
IPC: E03C1/262
Filed: 1994-12-08
Abstract: PURPOSE: To provide a water drain port lid used for a water drain port of a synthetic resin water-proof pan whereby hands and feet are not injured even if they are held by hands or depressed by feet by covering the entire surface of a water drain port cover base material with synthetic resin coat of a specified thickness. CONSTITUTION: Synthetic resin coat 2 of 50 to 500μm in thickness is applied to the entire surface of a metallic water drain port cover base material 2. When the thickness is below 50μm, there are cases that the top end of burrs at the edge part is not covered with the synthetic resin, and the top end of burrs may be peeled off by shock, etc. On the other hand, use of coating material of 500μm or more becomes useless. Also, even if burrs produced in cutting are present at the edge part of the base material of the water drain port cover, it is covered with the synthetic resin with a thickness capable of filling them. Therefore, even if hands and feet touch the burrs, they are not injured.

IPC: H01L21/268
Filed: 1988-12-28
Abstract: PURPOSE:To do favorable annealing of a substance to be annealed which contains substance having volatility and to facilitate the work by arranging the spots of light beams, which are applied to sweep the substance to be annealed, in such distribution that the energy becomes great by stages or continuously from the front side of the sweep to the rear side.

Title: Braking force distribution controllwer
Inventor: MORITA TAKAO
IPC: B60T8/48
Filed: 1992-12-11
Abstract: PURPOSE:To reduce the number of part items in a braking force distribution controller by making a booster valve, forming one part of an antiskid system, bear a function to selectively allow or check the pressure controlling action of a proportional valve. CONSTITUTION:A booster valve 17a is interposed in a first passage 15 between a master cylinder 13 and rear wheel cylinders 163, 164. In addition, two proportioning valves (PCV) 180 and 182 are installed in a third passage 15'' whose both ends are interconnected at both up- and down-stream sides of the booster valve 17a. When the booster valve 17a is opened, master cylinder pressure is added to both inlet and outlet ports of the proportional valves (PCV), so that any PCV action becomes nullified. On the other hand, the booster valve 17a is closed, the master cylinder pressure is added to the rear wheel cylinders via the third passage 15''. so this PCV action becomes operative. Thus, any PCV pressure control action working on the booster valve 17a is made up so as to allow or check it, through which the number of part item in this controller is reduced.

IPC: G11C11/401
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent increase in a chip size and a reduction in transmission rate when a triple well process is used by a method, wherein drive circuits, which are respectively constituted of P-MOS transistors having different well bias voltages, are arranged independently of each other. SOLUTION: A DRV region 100a, 100b arranged between subword lien decoder regions 20 and a DRV region 100b arranged between SA regions 30 have a P-MOS transistor. A first P-MOS transistor which is applied with two well bias voltages, and a second P-MOS transistor which is applied with one well bias voltage, are respectively arranged on the regions 100a and 100b independently of each other. The regions 100a and 100b are arranged into a Z-shape with a memory region 100 as a reference. As a result, increase in the chip side due to an increase in the DRV regions 100a and 100b can be prevented. Moreover, in the case where drive circuits are arranged outside of the region 100, a signal delay which is induced due to the increase in the regions 100a and 100b, can be solved.

Filed: 1989-12-21
Abstract: PURPOSE:To improve the safety of a passenger by forming an inclination angle for generating a necessary step difference between the contiguous staircases at a landing, on a guide rail at the landing. CONSTITUTION:Inside a landing 14, a pair of guiding rails 5 and 6 for guiding the front and rear wheels 2a and 2b of a staircase 2 are arranged. At the same time, a pair of guide rails 5 and 6 are inclined by an angle theta in the vertical direction, and a step difference is generated between a plurality of contiguous staircases 2 at the landing 14. Accordingly, the passengers who are transported to the mean landing through ascent and descent can know in visual and touch form that the mean landing 14 is not a getting-off port, from the variation of the step difference B between the contiguous staircases 2 and the height of a shifting handrail 4, and the restriction for foot stepping-on can be expected, and the turning-down on the basis of misunderstanding can be surely prevented. Further, the discomfortable feeling of the passenger who lowers from a high place and whose view field is shut out can be eliminated, and the designing consistency with the staircase having the landing and the designing performance due to accent can be improved without fail.
