Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To make current capacity between a power source and a changing-over means small and suppress the average current of a plurality of power sources by a method wherein a first electric potential, in the state of which the passage of an image-visualized particle through the gate of a control electrode is included, and a second electric potential, in the state of which no passage of the image-visualized particle through the gate of the control electrode is included, are applied through a capacitive element. SOLUTION: Control power source consist of voltage changing-over means 34a-34c, each contains an image signal control circuit, a high tension driver, a capacitor and a diode. Further, the output of the voltage changing-over means 34a-34c are respectively connected to ring electrodes controlling the passage of toner. Further, for example, 150V power source 35a and 35b and -200V power sources 36a and 36b are applied to the voltage changing-over means 34a and 34b. The current capacity of each power source supply potential to a large number of ring electrodes. Each one channel of each one of the voltage changing-over means 34a and 34b consists of an FET 37, a capacitor 38 and a diode 39. In this case, when the FET 37 is ON, -200V is applied to the ring electrode from the power source 36, while when the FET 37 is OFF, 150V is applied to the ring electrode from the power source 35.

Abstract: PURPOSE:To improve the gate turn-off characteristic of GTO without concentration of main current and gate current on basic portions by a construction wherein a pattern of the distribution of current density being the highest in the respective central portions of two finger elements. CONSTITUTION:The device has a structure of drawn-out electrode metal in which a cathode electrode metal 12 and a gate electrode metal 13 are so drawn out from the substantially-central positions of the respective cathode and gate regions 14 and 16 as to be symmetrical substantially to each other. A current density is the highest at the central position between E-F points of a finger element 12a of the cathode electrode metal 12 and also at the central position between G-H points of a finger element 13a of the gate electrode metal 13, and thus patterns of the distribution of the current density of the two are in accord with each other. Thereby the current breakdown due to a gate turn-off current (ITGQ) is prevented effectively, and the gate turn-off characteristic can be improved effectively.

Title: Transmitter-receiver for contactless ic card system
Inventor: FUJIMOTO MASAHIRO
IPC: G06K17/00
Filed: 1995-01-11
Abstract: PURPOSE: To improve the efficiency of signal transmission without reducing the Q of a resonance circuit in a responder by providing this transmitter-receiver with a means for detecting the tuning frequency of the responder and maintaining the oscillation frequency of a carrier oscillation means for sweeping the detected frequency at the tuning frequency. CONSTITUTION: A VCO 22 generates a carrier of which frequency is swept in accordance with a saw-tooth-wave output from a saw-tooth-wave generating circuit 20 and the carrier is transmitted to a responder without being modulated by a modulation circuit 3 through antenna coils 5, 11. When the carrier frequency F of an interrogator matches the tuning frequency f0 of a resonance circuit A consisting of the coil 11 and a capacitor 12 in the responder, peak voltage is generated in the coil 5. A demodulating circuit 6 demodulates the peak voltage and a peak searching circuit 23 allows a frequency holding circuit 24 to maintain the frequency F at the frequency f0 by controlling the VCC 22 or the circuit 20. Then the carrier is modulated based upon a signal outputted from a data processing circuit 2 and the modulated signal is amplified by a constant current driver circuit 4 to transmit it.  Consequently the efficiency of signal transmission can be improved without reducing the A of the circuit A.

Title: Chaining control system
Inventor: TSUZUKI HIROYUKI
IPC: G06N3/04
Filed: 1989-01-31
Abstract: PURPOSE:To easily transmit a signal by chaining between the blocks with the signal of a processing block by inputting a chain control input signal to one processing block, and outputting a chain output control signal from the block after the output processing of the processing block is completed. CONSTITUTION:An i-th processing block inputs a chain input control signal CSi-1 from an (i-1)th processing block through a connecting means 1-1 and outputs the chain output control signal to a (i+1)-th processing block. Then, a control means 1-2 sends a first chain control input signal CS0 to the first processing block and inputs a chain control output signal CSn from a final processing block (n). After each processing block finishes the processing, a processed result is outputted with time division by inputting the chain control input signal to the block and after the output processing is completed, the chain output control signal is outputted from the block. Thus, the signal is easily transmitted by chaining between the blocks with the signal of processing block.

IPC: B23B1/00
Filed: 1980-02-20
Abstract: PURPOSE: To facilitate the adjustment of the amplitute of tool vibration for cutting in sections the sludge produced while machining is being carried out.  
     CONSTITUTION: When a cam 13 is turned in concert with the rotation of a motor 2, a steel ball 15 that has been pressed against the surface of the cam 13 by means of the elastic force of a spring 12 starts to turn at half the speed of the cam while rotating in the same direction as that of the cam 13. The steel ball 15, which is being guided by the hole of an adjusting lever 16, rolls on the same circumference as that of the cam 13. The steel ball 15 rotates while vibrating after the unevenness of the cam 13, so that the vibration is conveyed to a cutting tool 29, allowing vibration machining. The change of the number of vibrations is carried out by changing the number of revolutions of the motor 2. Vibration adjustment can be readily done by changing the position of the steel ball 15 toward the diametric direction of the cam 13.

Title: Transmission output automatic control circuit
Inventor: TAKIZAWA MAYUMI
IPC: H03G3/20
Filed: 1990-01-31
Abstract: PURPOSE:To adjust an output level of a synthesized transmission signal optionally by varying a phase of a signal of one power amplifier with a phase of a signal of the other power amplifier. CONSTITUTION:Level control of a transmission signal synthesized and outputted by a synthesizer 6 is implemented by varying a phase of an output signal of a power amplifier 4 with respect to a phase of an output signal of a power amplifier 5 by a phase shifter 3. Thus, when an output level after the synthesis of the two power amplifiers 4, 5 is increased or decreased, the phase of the output signal of the power amplifier 4 is shifted increasingly or decreasingly by the phase control of the phase shifter 3 so as to adjust the transmission output level. Thus, the transmission output level is controlled to be constant without addition of an ALC circuit respectively to the power amplifiers 4, 5.
