Patent JP-H08227199-A (JP)
Title: Image forming device
Inventor: MATSUSHIRO HIROYUKI
IPC: G03G15/08
Filed: 1995-02-22
Abstract: PURPOSE: To form a good-quality image without requiring the useless moving time of a rotating body nor causing the undesired color mixture of toner in a developing unit by rotating the rotating body so that a distance of moving an optional developing unit to a specified reference position is made the shortest. CONSTITUTION: Except the time of image forming operation, that is, before and after the image forming operation, a developing device stands by and stops at the reference position of the developing device. Namely, a position of nearly a middle point between the developing roller 23-Y of the yellow developing unit 22-Y and the developing roller 23-K of a black developing unit 22-K where the rollers 23-Y and 23-K do not come into contact with a photoreceptor belt 1 is set as the reference position. For example, in the operation in the case image information represents single black color, the developing device is rotated from the reference position to the developing position of the black developing unit 22-K clockwise by 40 deg.. After finishing developing, the developing device is rotated back to the reference position.  At such a time, the developing device is controlled to be rotated counterclockwise by 40 deg. so that the moving distance may be the shortest. Therefore, the color mixture of the toner caused by the fact that another developing unit comes into contact with the belt 1 is prevented.

IPC: G01R15/20
Filed: 1987-02-18
Abstract: PURPOSE:To know when a lightning current flows and how large the current is and to analyze a damage due to an electric shock effectively by storing the peak value of a current waveform detected by a Rogowskii coil together with its its measurement date and time. CONSTITUTION:When a lightning current flows to an iron tower leg part 1, a voltage is developed across the Rogowskii coil 2. When the output voltage of an input adjusting circuit 3 exceeds a specific level, a trigger circuit 4 operates to make a microcomputer 8 ready to operate. The output of the input adjusting device 3 is inputted to a peak holding circuit 5 and the peak value of the lightning current is stored in a memory by the CPU of the microcomputer 8 through an impedance converting circuit 6 and an AD converter 7. The microcomputer 8, on the other hand, has a time signal generation part 9 and stores the value together with its date and time. The storage contents are displayed on a display 10 or printed out on a printer 11 a certain period later.

Title: Pressure control actuator
Inventor: TSUKAMOTO MASAHIRO
IPC: F16J1/10
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized and reliable pressure control actuator while reducing shocks upon lowering of hydraulic pressure. SOLUTION: A solenoid cut-off valve 5 is incorporated in a brake fluid passage between a master cylinder 2 and a wheel cylinder 3 in a vehicle, and communicates with a control cylinder 12, and a piston 13 embedded therein with a magnet 16 is accommodated in a pressure chamber 12a in the cylinder 12. A piston stopper 12c is formed in the lower part of the cylinder 12. A piston drive shaft 20 made of a magnetic material and the piston 13 are attracted together by an attraction force by a magnetism and during manipulation of the brake, they are integrally incorporated with each other, and are moved in the vertical direction so as to control the brake hydraulic pressure. When the brake is released, the piston 13 is retracted up to a position where it abuts against the piston stopper 12c while the piston drive shaft 20 abuts against a movable spring seat 31 so as to carry out overstroking. With this arrangement, no spring for urging the piston 13 toward the initial position is required, and accordingly, the piston 13 is prevented from being inclined or being eccentric. Thereby it is possible to provide a small-sized pressure control actuator and to prevent occurrence of leakage of brake fluid.

Abstract: PURPOSE:To provide the apparatus and method for automatically pouring molten metal without developing dripping of the remained molten metal from supplying/discharging hole in a ladle by promoting discharge of the molten metal to be poured in the ladle at the time of pouring the molten metal into an injection sleeve in a die casting machine. CONSTITUTION:The ladle 5 is selectively communicated/ shut out with and from the air-through opening/closing means 4, but a molten metal pressurizing mechanism 20 and remained metallic metal removal mechanism 30 are connected with this opening/closing means 4 through pipings 40, 40a, 40b, and at the time of pouring the molten metal, small capacity or low pressure of pressurized fluid is introduced into the molten metal in the ladle 3 from molten metal pressurizing mechanism 20 through opening/closing means. After completing pouring of the molten metal, large capacity or high pressure of the pressurized fluid is introduced into the ladle 3 from the remained molten metal removal mechanism 30. As the small capacity or the low pressure of pressurized fluid is applied on the molten metal in the ladle 3 at the time of pouring the molten metal, the discharge of molten metal from the ladle 3 is promoted, and as the large capacity or the high pressure of pressurized fluid is applied on to the molten metal in the ladle 3 after completing the pouring of molten metal, the remained molten metal is discharged, and the dripping of remained molten metal from the supplying/ discharging hole 3c in the ladle is not caused. Therefore, the pouring time is shortened and working environment is kept to good.

Title: Braking circuit for electric motor
Inventor: MIKI HIROSHI
IPC: H02P3/22
Filed: 1980-03-19
Abstract: PURPOSE:To reduce a generated calorie of braking resistance and provide an effective braking effect on an electric motor by detecting a DC voltage on an inverter main circuit, compare it with a set level to relase or charge a braking resistance. CONSTITUTION:An AC power supply is rectified by means of a rectifier 1 and is smoothed by a smoothing condenser 2. Then an electric motor 4 is driven by a voltage-type transistor inverter 3. In addition, a voltage of the condenser 2 is supplied to a comparison circuit 52 through the intermediary of a stabilization circuit 52, and is compared with a set level to control a drive circuit 53. Following this process, a transistor Tr is provided with a continuity to charge a braking resistance 6. Consequently, it is possible to charge the braking resistance 6 when the voltage of the condenser 2 increases under a generation braking mode when the electric motor 4 is controlled to a moderation rate and release the braking resistance when the voltage decreases. Thus a calorific capacity can be reduced by inserting a braking resistance 6 only during a period when a voltage is high.
