Title: Electromagnetic actuator driving circuit
Inventor: YONEKURA KOICHIRO
IPC: F02M63/00
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent the exposure of high-voltage in the case where a connector for connecting a driving circuit and a fuel injection valve(solenoid) is disconnected. SOLUTION: At the time of rise of the injection pulse signal, switching elements Q1, Q2 are turned on, and high-voltage is applied from a high-voltage power source 1 to a solenoid 3 so as to open the valve. After the solenoid valve is opened, switching elements Q2, Q3 are turned on, and low-voltage is applied from a low-voltage power source 2 for holding. At the time of fall of the injection pulse signal, switching elements Q4, Q5 are turned on, and high-voltage is applied from the high-voltage power source 2 in the opposite direction. At this stage, fine current is flowed to the solenoid 3 through resistors R1-R3 when the switching elements Q1-Q5 are turned off. Terminal voltage of the resistor R3 is monitored by a comparator 7 so as to detect the existence of disconnection.  When disconnection is detected, transmission of the injection pulse signal is cut by a gate unit 8 so as to inhibit the drive.

Title: Shifting of operation of induction motor
Inventor: KIMURA TAKANOBU
IPC: H02P25/18
Filed: 1978-04-26
Abstract: PURPOSE: To prevent an excessive current from flowing through the primary side of an induction motor driven by a commercial-frequency power source and smoothly shift the motor to a low speed, by replacing the power source by a low-frequency power source after connecting an external secondary resistor to the induction motor.  
     CONSTITUTION: A low-speed shifting circuit consists of circuit breakers MCB1, MCB2, electromagnetic contactors X, Y, F, F, 1A, P, external resistors R1, R2, a speed relay ZS, a contact ZS- b which is closed when the motor is shifted to the low speed and an overcurent relay OL. To shift the motor to the low speed, the electromagnetic contactors P, 1A are opened to raise the secondary resistance to the induction motor 1M to prepare for the suppression of the primary current and the commercial-frequency power source is then replaced by the low-frequency power source. As a result, the adverse effect on the low-frequency power source is prevented even if the speed of the induction motor is higher than a synchronous speed corresponding to the frequency of the power source when this power source is applied. After a required lag time, the electromagnetic contactors P, 1A are sequentially closed to increase the torque. If the speed of the motor 1M is too low, the motor can be accelerated to the prescribed low speed.

Title: Frequency control method of coupling oscillator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H3/04
Filed: 1982-03-29
Abstract: PURPOSE:To reduce the defect factor due to the temperature characteristics and to realize a reduction of cost, by controlling the primary temperature coefficient after confirming the temperature characteristics of each oscillator. CONSTITUTION:An oscillator is designed so as to obtain the optimum temperature characteristics that is obtained before the frequency of a coupling oscillator is controlled as well as an optimum resonance frequency of the primary oscillation. The plus or minus value of the primary temperature coefficient alpha is confirmed by a heat souce of a heater, etc. after forming a crystal oscillator by etching. When the coefficient alpha is plus, at least one of the weights 12-15 of four corners of an oscillating part are dispersed by a laser. While the weights 10 and 11 of at least one area nearly at the center edge part in the lengthwise direction of the oscillating part are dispersed by a laser if the coefficient alpha is minus. Thus the temperature coefficient alpha is set at 0. Then the resonance frequency of the primary oscillation is set at the reference frequency.

Inventor: ENDOU TERUMI
IPC: H03K3/03
Filed: 1979-04-23
Abstract: PURPOSE:To make unnecessary the buffer circuit by commonly using the inverter at the post stage as the impedance converting function. CONSTITUTION:When the output of the inverter section C is inverted from L to H at time T0, the PNP transistor TR1 of the SEPP type inverter section D at the next stage is OFF and the NPN transistor TR2 is ON, and the output at the point C is from H to L. Accordingly, the charging current flows to the capacitor C1 through the resistor R1 and the input at point (a) of the inverter IN1' is increased. The moment when the potential at the point (a) is equal to the threshold level at time T1, the output of IN1' is inverted from H to L, TR1 of the SEPP at next stage is ON and TR2 is OFF, and the output at point (c) is inverted instantly from L to H. Thus, the potential at the input of point (a) is instantly increased. Differentiated current flows to the capacitor C1 and resistor R1 between the time T1 and T2, the potential at point (a) is decreased, and when the potential at point (a) is lowered to the threshold level, the output of IN1' is inverted from L to H.

Filed: 1989-03-02
Abstract: PURPOSE:To form easily on a dial plate characters, abbreviations and marks which can be seen in three dimensions, by plating a dial plate base and by forming a non-conductive film layer thereon by coating. CONSTITUTION:A dial plate base 1 is formed to be 0.3mm thick out of a brass plate and coating density graduation is made radially. Next, the dial plate base 1 is plated with nickel or silver and clear coating is applied on the plating layer thus formed, so as to provide a coating layer 2. Subsequently, the coating layer 2 is cut in parts of abbreviations from above by a metal tool so as to remove the coating layer 2 therefrom so that the metal surface of the dial plate base 1 be exposed. Then, a dial plate thus prepared is immersed in an electrodeposition coating liquid made up of cation-type acrylic electrodeposition coating resin containing a black pigment, and while the electrodeposition coating liquid is agitated, a direct current of 100V is made to flow for one minute between the dial plate as a cathode and a stainless steel plate as an anode. Subsequently, the dial plate is heated for 20 minutes by a heating furnace of 150 deg.C to harden an electrodeposited coating film and thereby an electrodeposition coating layer 3 is formed. According to this method, black abbreviations can be formed on the silver-colored surface of the dial plate.
