Title: Phase information detector for synchronous motor
Inventor: AISAKA TOORU
IPC: H02P25/02
Filed: 1980-10-24
Abstract: PURPOSE:To improve the responsing characteristic of a linear synchronous motor in the speed control by producing phase information of induced voltage without delay time. CONSTITUTION:An induced voltage 4U containing harmonic component is inputted from an induced voltage calculator 3U to a Bessel type low pass filter 5U having a constant delay time based on the U-phase voltage 1U and current 2U fed from a power converter. The delay phase angle of the induced voltage 6U is proportional to the frequency, and the peak value is proportional to the frequency. When this voltage is divided by the output of a 3-phase full wave rectifying circuit 7 by a  divider 9U, normalized induced voltage 10U having constant peak value is produced.  When the rectified voltage 8 is amplified by an amplifier 13, the output voltage 8 a  is inputted to a comparator 11 as a reference voltage, and is compared with the voltage 10U by the comparator 11, a short waveform 12U having phase coincident to the fundamental wave of the induced voltage 4U can be obtained. This phase information processing is executed also for the V-phase and W-phase.

Title: Electrostatic deflector
Inventor: KOMATSUBARA TAKAO
IPC: H01J37/147
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To realize the reduction in the number of part items and the size and a highly precise assembling in a short time by fixing a plurality of electrode elements divided at a specified angle to holding members for separately insulating, aligning and supporting them along the axial direction so as to form a divided electrode surface of a specified angle in plane by an insulating member. SOLUTION: Potentially independent electrode elements 3-6 divided at 360/n deg. (n=4) form a divided electrode surface of 360 deg. in plane, and the electrode surface forming part of the other electrode element is inserted to a central through- hole to form a four-divided electron beam axially fitted electrode. The electrode elements 3-6, the electrode elements 9-13 of a blanking electrode, earth electrodes 7, 8, a holder 13, a diaphragm 14 and a base 15 are fitted to prescribed slits of holding members 1, 2. The electrode elements 3-9, 9-12 are precisely positioned by inserting an assembling jig to a positioning hole P, and the fitting parts with the holding members 1, 2 are fixed by a glass softened at a high temperature. The number of parts is reduced because screwing is not adapted, and this device is suitably usable even in super vacuum.

Title: Corotron overcurrent controller
Inventor: WATANABE SADAO
IPC: G03G15/02
Filed: 1985-07-09
Abstract: PURPOSE:To continue the subsequent copying work in a certain degree by fixing the output voltage when the discharging current value reaches a certain current value independently of protection from an overcurrent due to accidents. CONSTITUTION:When a potential Vp at a point P rises to reach a voltage value V1 of a constant voltage source 14, the detection signal is superposed on a monitor signal of the output of a comparator 11. When this detection signal is inputted, a CPU 10 instructs a high voltage power source 7 to fix the output voltage by a remote signal. Since the copy work is possible hereafter though the picture quality is degraded and the voltage applied to a corona wire 5 does not rise though copying is continued, arcing, break of the corona wire 5, etc. are not caused.

IPC: G02B6/00
Filed: 1992-05-18
Abstract: PURPOSE:To deposit fine glass particles for the optical fiber in good yield and at a high rate by the OVD process. CONSTITUTION:Charging nozzles 23 and 25 are provided in parallel on both sides of a burner 21, and a soot 3 is reciprocated with respect to the burner 21. When the soot 3 is moved in the A direction, ion 44 is emitted toward the soot 3 from the nozzle 25.

An electrode wire 22 is furnished in the burner 21, and an oxyhydrogen flame 41 contg. positively charged fine glass particles is injected against the soot 3. Since the soot 3 is charged by the negative ion 44 and the positively charged fine glass particles are injected against the soot 3 from the burner 21, the deposition yield is improved by the electrostatic force in addition to the injection force. When the soot 3 is moved in the B direction, the nozzle 23 is actuated instead of the nozzle 25, and negative ion 43 is emitted.

Abstract: PURPOSE: To prevent the deenergization of a field circuit, by continuously driving a parallel circuit at the trouble of (n-1) chopper circuits until the troubled circuits are disconnected and by disconnecting n chopper circuits at their trouble while connecting a resistor-type field adjustment circuit.  
     CONSTITUTION: When a chopper circuit 4-1 develops a trouble, a trouble signal is entered from a point A. The trouble signal f-1 is detected from an OR circuit 20-1. Because the AND of the trouble signal with a normality signal g-2 relating to another chopper circuit 4-2 is taken, a signal j-1 appears on a point C to keep the chopper circuit 4-1 closed. At that time, a break signal a-1 relating to a circuit breaker 6-1 appears on a point J to open the circuit breaker. When the circuit breaker 6-1 is opened, the chopper circuit 4-1 is restored into normal operation. When both the chopper circuits 4-1, 4-2 become defective, a signal (b) for closing a contactor 10 for a resistor circuit appears on a point G. When the contactor 10 is closed, an opening instruction for the circuit breakers 6-1, 6-2 is applied.

Abstract: PURPOSE:To attain a high speed switching operation with a simple constitution by connecting the source and drain of an FET for driving with the gate and source of an FET switch element. CONSTITUTION:A voltage Vs in an H level is added to the base of a transistor Tr2, and the Tr2 is turned on. When the Tr2 is turned on, a gate voltage VG3 of an FETTr3 for driving is decreased to a negative power source Vdd-. Then, a voltage between the gate and source of the Tr3 obtained through a resistance R2 is increased to the negative direction, and when the voltage is less than the pinch off voltage of the Tr3, the Tr3 is turned off. When the Tr3 is turned off, a switch element Tr1 is turned off. Next, the voltage in an L level is added to the base of the Tr2, and the Tr2 is turned off. Then, the charge of a capacity between the gate and source of the Tr3 is discharged, and the Tr3 is turned on. When the Tr3 is turned on, the Tr1 is turned on.
