Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device, having satisfactory crystallization of a polycrystalline semiconductor film, few defects at an interface, thus a large field effect mobility, further satisfactory threshold voltage characteristics and sub-threshold characteristics. SOLUTION: Laser light is irradiated to the surface of an amorphous silicon film 32 formed on a glass substrate 31 under an oxygen atmosphere, to form a polysilicon film 33 and to form a silicon oxide film 34 on the polysilicon film 33. Accordingly, this can reduce dangling bonds produced at the interface of the polysilicon film 33 and prevent impurities from mixing, thereby producing proper crystallization having few defects at the interface. Furthermore, since the semiconductor oxide film is formed at a high temperature, it can be made satisfactory in quality. Therefore, a semiconductor device having satisfactory TFT characteristics can be produced.

Abstract: PROBLEM TO BE SOLVED: To make a judgement on an impact, in which a proper hit is generated even by a small displayed object on a screen, and perform realer processing after the impact by a little computing. SOLUTION: An impact judging area A, which is annexed to an object (a bat T) serving as a target of the impact judgement, is set so that the impact judgement can be made between the area A, which has a simpler shape and serves as a substitute for the bat T, and a ball B. The area A is composed of a plurality of sub-areas (a fly area F, a hit area H, and a grounder area G), and conditions of batted balls to be processed after the impact are set from one sub-area to another. When the area A is taken as the bat T, setting contents are based on states of the actual batted balls in the positions of the sub-areas. Thus, the realer batted balls can be created by the little computing.

IPC: F16H61/662
Filed: 2001-09-13
Abstract: PROBLEM TO BE SOLVED: To improve an hill-climbing force on hill-climbing and an engine brake force on hill-descending in a maintenance vehicle. SOLUTION: The maintenance vehicle travels mounting working equipment driven by an engine. When the maintenance vehicle goes into hill-climbing mode or hill-descending mode, that is, hill-climbing/descending mode Df, an automatic transmission mounted on the maintenance vehicle is set in the hill- climbing/descending mode in the change gear ratio. The hill-climbing/descending mode Df is selected with a shift lever operation or automatically switched by means for detecting the hill-climbing/descending. When the hill-climbing/ descending mode is set, the change gear ratio is controlled to maximize. In the hill-climbing/descending mode, the change gear ratio is not changed on hill-climbing to enable the stable hill-climbing traveling.  A great engine brake force is also gained on the hill-descending to improve the safety on the hill- descending and prevent turfs from damaging with a quick service.

Title: Method of measuring self-discharge amount of lithium ion secondary cell and method of manufacturing lithium ion secondary cell
Inventor: SUGIE JUNJI
IPC: H01M10/05
Filed: 2001-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a method of measuring rapidly and conveniently a self- discharge amount of a lithium ion secondary cell. SOLUTION: The measuring method comprises the steps of: measuring the terminal voltages of the lithium ion secondary cell during the initial charging of the cell at a low current density after a process of manufacturing the cell; and estimating a self-discharge amount, based on the terminal voltages. This method allows measuring the self-discharge amount in only a short charging time after the cell manufacturing. As the conditioning to repeat several times charge/discharge after the cell manufacturing is generally conducted to stabilize the cell performance, this object can be achieved only by modifying part of the conventional conditioning process without any additional process to measure the self-discharge amount.

Title: Switching circuit
Inventor: HIDA TAKUSHI
IPC: H03K17/08
Filed: 2001-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a switching circuit which can prevent rush current, while miniaturizing the circuit and preventing heat generation. SOLUTION: When a switching drive 3 is turned on and at the moment a switch element 2 is turned on, a ΔV detection circuit 4a detects a higher rate for the rise of output voltage Vso than a fixed rate, and turns a switch 4b on and turns off the switch element 2 by a signal a. At this point, electric potential of a control terminal 2C rises, and an instantaneous breaker 4 takes an instantaneous breaking action to return the switch element 2 to off. Then the circuit 4a turns the switch 4b off and the switch element 2 on again by the signal a. As long as the circuit 4a detects that the output voltage Vso rises at a rate higher than a fixed rising rate at the moment the switch element 2 is turned on, the instantaneous breaker 4 takes instantaneous breaking action, and the rising rate is detected at the next moment of its turning on.  Thus an output capacitor C2 is charged gradually and intermittently.
