Title: Series resonance converter
Inventor: KII YASUO
IPC: H02M3/28
Filed: 1993-09-14
Abstract: PURPOSE:To prevent the operation frequency of a series resonance converter from changing greatly while reducing its switching loss even when its output frequency has lowered. CONSTITUTION:A series resonance converter is provided with a current transformer 41 in a resonance current route. The secondary side of the current transformer is connected to input terminals 3, 5 through a rectifier circuit 43, auxiliary switching element FET 45, and diode 47. When the output voltage is normal, the auxiliary switching element FET 45 is turned on to perform ordinary operation. When the output voltage lowers and the resonance current I has a longer trailing, the auxiliary switching element FET 45 is turned off to feed back part of the energy of the resonance current I to an input DC power supply 1, to reduce the current to zero quickly, thereby softly turning off the main switching elements IGBT 17 and 19.

IPC: B41J29/00
Filed: 1993-10-08
Abstract: PURPOSE: To increase the number of the ink jet nozzles of a printing head without increasing the number of the interconnection lines between the printing head (hereinbelow referred to as PH) and a printer. CONSTITUTION: The number of interconnection elements 24, 26, 28 for transmitting a printing command to a PH 14 from a printer is reduced by the use of a PH driving circuit 30. The PH driving circuit 30 is equipped with the matrix of a driver controlled by a gate and feed and control connectors. By enabling the line and row of the driver by using the feed and control connectors, the number of the connectors is reduced. In order to further reduce the number of the control connectors, a multiplexer can be arranged. A separate PH driving circuit 30 is equipped with a resistor 40 for the convertion to a format for adding the series stream of the printing enabling signal from the printer to a switching device related to one or more heater resistor at the same time.  An address generator 34 on the PH 14 generates an address signal corresponding to the address generating signal from the printer. The printer supplies constant power to the PH 14 and the energization of the heater resistor becomes the function of the address signal and the printing enable signal but not the function of power.

Title: Throttle valve controller of engine
Inventor: SHITANI YUJI
IPC: F02D45/00
Filed: 1990-09-20
Abstract: PURPOSE:To ensure throttle valve operating speed which agrees with the demand of an operator by deciding whether a motor drive frequency is shifted to the high frequency side or low frequency side from its resonance zone in accordance with accelerator pedal stepping operation speed. CONSTITUTION:A controller 25 outputs a throttle valve control opening signal and a throttle valve control current signal to a throttle valve drive driver 32 based on the detected signal of an accelerator opening sensor 21 which measures the amount of stepping of an accelerator pedal 19 so as to control a throttle valve drive motor 15. When the drive frequency of the motor 15 is shifted from its resonance zone, it is set to a high frequency which exceeds its resonance zone when the average value of variation amounts of accelerator pedal opening is large, and set to a low frequency less than its resonance zone when the average value of the variation amounts of accelerator pedal is small. Consequently, it is possible to obtain operating speed of a throttle valve 10 which approximately agrees with operation control of a operator and ensure opening control of the throttle valve 10 while restricting or eliminating a sense of incongruity which is given to the operator.
