Title: Controller for electric rolling stock
Inventor: YOMO SUSUMU
IPC: B60L3/00
Filed: 1990-08-09
Abstract: PURPOSE:To protect a charging resistor against burning by detecting DC voltage of DC trolley wire V1 and the terminal voltage V2 of a capacitor on the input side of an inverter and turning an input side switch OFF if V1>V2 in case of powering and if V1<V2 in case of regeneration. CONSTITUTION:DC power from a trolley 1 drives an inverter 8 and charges a filter capacitor 7. A voltage detector 13 detects the trolley voltage V1 whereas a voltage detector 14 detects the terminal voltage V2 of a capacitor 7. During powering or normal operation with a regeneration signal 10, V1=V2 and a detecting circuit 17 does not produce an output. Consequently, contact 18a remains is ON state thus sustaining relays 3a, 5a in energized state and a gate control circuit 12 drives the inverter 8. When current flows through a resistor 4 due to insufficient contact of a switch 5, V1=V2 is applied for powering or regeneration and the detection circuit 17 produces an output to a relay 18 so as to turn the relays 3a, 5a OFF and thereby the control circuit 12 does not drive the inverter 8. According to the arrangement, the resistor 4 is protected easily against burning.

Abstract: PURPOSE:To apply output stably to a variation of a load to a matter to be heated, by a method wherein an operation speed is detected, feedback of its signal is performed to an electric output system, predetermined electric power is applied to the system and voltage control between electrodes is performed by controlling capacity of a variable condenser to a difference in a paper width at a predetermined speed. CONSTITUTION:Electric power proportional to (preset maximum sheet width) X(operation speed) is applied to a matter to be heated through an operational circuit 7 which has been calculated and incorporated beforehand within a high- frequency oscillator 3 as an output control method to the matter to be heated. Then predetermined output is applied to a load through the operational circuit 7 based on the speed detected by an operation speed detecting sensor 4. Therefore, when the operation speed is decided, the maximum value of the output corresponding to the speed is set up. Then feedback of a signal based on a paper width detecting sensor 5 is formed to a difference in a paper width at the same speed and voltage between electrodes is controlled by varying capacity of a variable condenser 11. With this construction, output control is stabilized and discharge is prevented.

Filed: 1992-08-06
Abstract: PURPOSE:To enable the cleaning of an electrifying roller and a transferring roller with a simple system by impressing voltage having reverse polarity to toner on a metallic member in contact with the roller. CONSTITUTION:An electrifying roller cleaning device 3 is provided with a metallic shaft 30 in contact with the leading edge of a brush, a recovery container 31 storing recovered toner and a power source part 32 impressing the voltage on the shaft 30. When the electrifying roller 1 starts rotating at the time of starting an electrifying stage in an image forming process and before the roller 1 is stopped at the time of finishing the stage, the voltage having the reverse polarity to the toner is impressed on the shaft 30 by a power source part 32. Furthermore, the leading edge of the brush is successively brought into contact with the shaft 30 by the rotation of the roller 1, and the positive-electrified toner sticks to the shaft 30. The toner merely sticking to the brush in a non- electrified state is shaken off and drops in the recovery container 31 when the brush is brought into contact with the shaft 30 and vibrated. A transfer roller cleaning device 4 has similar constitution.

Abstract: PURPOSE:To achieve the high-speed etching of Si and polysilicon by varying the position of a carbon plate or the like and the area of the part to be exposed to plasma and separating it electrically so as to enable independent application of DC or RF bias. CONSTITUTION:A carbon plate 15 or the like a part of which or the whole of which is albe to be put in plasma is held in an etching chamber 8 by a holding mechanism 17 through an insulator 16 and position of the carbon plate 15 or the like and an area of the part to be exposed to the plasma are varied by adjustment of the holding mechanism 17.

A shape of the carbon plate itself and the area are also variable. This constitution is effective particularly when oxidization of the surface of Si can be prevented by the carbon plate or the like of relatively small area. Consequently, it becomes possible to put the carbon plate 15 or the like in discharge with a form according to conditions of the discharge.

Title: Method of correcting resistance value of resistor
Inventor: ARAI TOSHIO
IPC: H01C17/24
Filed: 1989-08-16
Abstract: PURPOSE:To increase resistance value precision and reduce correction distance, by making a beam spot diameter smaller as resistance approaches a target correction resistance value. CONSTITUTION:A resistor coating film 1 is printed on a ceramic substrate 3, electrodes 2 are arranged on both ends, and the resistance value is determined by the volume of the coating film 1 between electrodes 2. At the time of correcting the resistance value, cutting groove width is narrowed by heat energy of laser light, and resistance value correction is performed. The diameter of a beam spot at the initial cutting is made large like a correction groove 4. As resistance approaches a target correction value, the beam spot diameter is made smaller. Thereby cutting distance is reduced, correction time is shortened, and resistance value correction precision can be increased.
