Patent JP-S60176839-A (JP)
Title: Head lamp driving device
Inventor: KAWAI TANEICHI
IPC: B60Q1/05
Filed: 1984-02-23
Abstract: PURPOSE:To aim at safety in a way of cutting off an electric current in time of motor locking, by starting a timing motion in time of motor energizing but stopping it in time of motor stopping, while making a device generate a stop signal if the motor energizing continues for the setting time long from the start of the motor energizing. CONSTITUTION:In a safety circuit 90, a transistor 91 turns to OFF when relay coils 22a and 71a of a motor driver 70 are energized with current L and thereby a condenser 93 is charged as specified. When it passes through t1, it goes beyond reference voltage V1 of a comparator 95, and output of this comparator 95 turns to H whereby output of a motor 40 goes up, thus an arm is driven into rotation by strong force. Accordingly, even if the required driving force of a head lamp grows large due to lost motion, wear, etc., the specified drive is performable. In addition, when it comes to t2, voltage of the condenser 93 goes beyond reference voltage V2 and thereby output of a comparator 94 comes to H, turning a transistor 96 to ON, and transistors 74 and 76 come to L so that a continuous rating current for relay coils 72a and 71a is cut off, thus the motor stops. With this constitution, in time of trouble happening, it stops automatically before the motor generates heat, thus a device mechanism is protected.

Title: Electric water heater
Inventor: SERIZAWA TAKANOBU
IPC: F24D19/10
Filed: 1989-02-15
Abstract: PURPOSE:To effectively and previously prevent a water cut phenomenon from being produced by providing a bypassing hot water outlet tube on a hot water storing tank and a three-way valve at the joint of said bypassing outlet tube and a hot water outlet tube, and making selectable said hot water outlet tube and said bypassing hot water outlet tube with use of said three-way valve. CONSTITUTION:High temperature hot water 20 stored in a hot water storing tank 10 is supplied through a three-way valve 18 typically operated by a controller 15 or manually and a bypassing hot water outlet tube 17. When high temperature hot water required for bathing, showering, etc., is supplied from the hot water from the bypassing hot water outlet tube 17, an interface between the high temperature hot water 20 and the supply water 21 is raised, and a temperature sensor 14 detects the lowering of the water temperature. With the detection of the temperature, power is supplied to a heater 13 to heat the supply water in the hot water storing tank 10 to a predetermined temperature. The heating at this time is not for substantially the total amount 1 in the hot water storing tank 10, but for stored water ranging between a region 1b and a region 1c, so that the supply water is rapidly raised in its temperature and heated for a short period of time.

Title: Contour extraction method for mesh graphics
Inventor: MOCHIDA MASAHISA
IPC: G06T9/20
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To extract an accurate contour for a mesh graphics where the binarized image information are optionally arrayed in every unit grating and even for such a graphics that branched out in the single grating width from a contour extraction start grating. SOLUTION: At first, a unit grating is found out of a mesh graphics as a contour extraction start point and also the extracting direction is initialized (101). Then the contour of the graphics is tracked clockwise with the contour extraction start grating defined as a start point (102 to 113). When the extraction of the unit grating that is tracked right before the clockwise tracking returns to the contour extraction start grating is set in a direction other than the prescribed one (YES of 104, 107 and 110), the contour extraction processing ends. If the extraction of the unit grating is set in the prescribed direction (YES of 113), the graphics contour is tracked clockwise again based on the returned contour extraction start grating and its extracting direction (202 to 213).

Title: Wrist watch band
Inventor: TAKAYAMA TAKASHI
IPC: A44C5/04
Filed: 1989-02-14
Abstract: PURPOSE:To reduce the weight and to apply colors freely by forming with synthetic fiber a plurality of rear and front surface coupling pieces connected to the side of the watch with the coupling pieces on the watch side and a plurality of surface coupling pieces and by energizing the arrangement interval in the direction of reduction of intervals with the energizing member. CONSTITUTION:A front surface coupling piece 2 and a rear surface coupling piece 3 are formed with synthetic fiber. In the state where a force is not applied in the direction of separating each front surface coupling pieces 2 and each rear surface coupling member 3, both the front surface and rear surface coupling pieces 2, 3 are brought into contact with the adjacent front surface and rear surface coupling pieces 2, 3. When a force is applied in the direction against the tensile force of the energizing member 5, each front surface and rear surface coupling pieces 2, 3 are displaced by revolving respectively upon each recessed and projected mating part 6. Along with it, adjacent front surface and rear surface coupling pieces 2, 3 are separated. Consequently the band can be worn in a good condition regardless of the size of the wrist. Each component can be easily molded, for example, with injection molding of synthetic fiber. Various colors can be freely combined and the cost of manufacturing the bands can be largely reduced. Besides they can be manufactured in light weight, thus making it possible to eliminate uncomfortable feeling in wearing due to a heavy weight.
