Title: Ac output voltage control system for pwm inverter
Inventor: FUJITA HIROYOSHI
IPC: H02P21/36
Filed: 1989-02-02
Abstract: PURPOSE:To enable smooth torque control by providing a first comparing means for carrying out flux operation and a second comparing means for carrying out torque operation then comparing an estimated AC voltage to be applied onto an induction motor with an inverter AC voltage command value thereby regulating a flux command. CONSTITUTION:First comparing means 711 for producing a flux increment/ decrement signal so that the absolute value of flux vector follows to a flux command provided within a predetermined allowable error, and second comparing means 712 for producing a torque increment/decrement signal so that instantaneous value of torque follows to a torque command provided within a predetermined allowable range are provided. AC voltage to be applied onto an induction motor 6 is estimated through utilization of an output signal from the second comparing means 712, then the estimated voltage is compared with AC voltage command value VREF, of an inverter 3, and if the estimated voltage is higher than VREF the flux command is reduced according to the difference. By such arrangement, smooth torque control can be carried out with reference to the first comparing means 711.

Title: Auxiliary steering gear for vehicle
Inventor: KAWAGOE KENJI
IPC: B62D5/07
Filed: 1988-02-04
Abstract: PURPOSE:To enable a rear wheel to be stably controlled by most suitably controlling a pressure control valve, which controls a steering angle of the rear wheel, receiving no influence by an engine speed and a rotary speed of an oil hydraulic pump. CONSTITUTION:A pressure control valve 12, which controls a rear wheel for its steered angle, is controlled by a controller 17. The controller 17 inputs signals from a car speed sensor 19, steering angle sensor 18 and a detector of a drive speed of an oil hydraulic pump or an engine speed. The controller 17 provides a circuit which is able to correct an arithmetic value controlling the pressure control valve 12 in accordance with a change of pump delivery amount or engine speed When it decreases or increases, thus the rear wheel permits its actual steered angle to be obtained with no influence by a pump speed and the engine speed.

Title: Color killer circuit
Inventor: MISAKI TAKASHI
IPC: H04N9/87
Filed: 1981-02-18
Abstract: PURPOSE:To increase the allowance for discriminaton miss, by connecting an input terminal of a color burst signal to a filter where 4.25MHz passes through and 4.4MHz is attenuated and discriminating the output variance period. CONSTITUTION:A filter 4 has a characteristic of 4.25MHz as passing region and 4.4MHz and 4.4MHz as attenuated regions. In case of a SECAM system color television signal (SECAM signal), an output waveform of a ceramic filter 4 is d' and a fH/2 AMP5 (where; fH is horizontal frequency) generates a signal e', and in case of a PAL color television signal where a Schmitt circuit 7 discriminates a SECAM signal, the output waveform of a ceramic filter 4 is d'' and the signal level is small. Thus, when a PAL signal is in dubbing, even if the level variance is produced into a waveform d''', since the energy of fH/2 is small, the output of the AMP5 is small as e' and the circuit 7 never discrminates the signal as a SECAM signal.

Title: Anode for rotary anode x-ray tube
Inventor: KOTABE MUNETOMO
IPC: H01J35/10
Filed: 1982-02-17
Abstract: PURPOSE:To prevent a slip from being generated between a carbon target and a rotary shaft. CONSTITUTION:The internal surface of the axial fixation hole of the carbon 2 of a carbon target 1 is inserted in  rotary shaft 5 through a metal coat of approximately 0.5mm. thick and the carbon target 1 is tightened on the rotary shaft 5 with a nut 7. Since the said rotary shaft 5 is normally composed of molybdenum or molybdate alloys, it is recommended that the same types of materials such as molybdenum, tungusten, or the like should be used as the said metal coat 4. When the carbon target 1 and the rotary shaft 5 are located under high temperature and high vacuum conditions during operation, the meatl coat 4 is activated under the high temperature and high vacuum conditions and both the metal coat 4 and the rotary shaft 5 generate cohesion. Consequently, since both the rotary shaft 5 and the carbon 2 are made to adhere firmly through the metal coat 4, a slip between them can be prevented from being generated.
