Inventor: IMAI OSAMU
IPC: H01C7/10
Filed: 1989-02-21
Abstract: PURPOSE:To improve the voltage non-linear characteristics in a large current region and to improve electro-life and surge-strength by incorporating zinc oxide phase of Zn1+xO (x>=1X10<-5>) into zinc oxide particles in a sintered body. CONSTITUTION:In a sintered body which has a main element of zinc oxide and is provided with voltage non-linear characteristics, zinc oxide phase of Zn1+xO (x>=1X10<-5>) is incorporated into zinc oxide particles. That is, small resistance of each particle and uniform potential barrier among grain boundaries can be realized by incorporating a phase whose oxygen is less than a constant ratio. Thereby, it becomes possible to improve voltage non-linear characteristics in a large current region and to acquire a voltage non-linear resistor of good electro-life and surge strength.

Title: Delay circuit
Inventor: HANDA JINKOU
IPC: H03K5/13
Filed: 1983-03-10
Abstract: PURPOSE:To prevent the variance of the delay time by making conductive a transistor connected to the output terminal of a charging/discharging circuit during the breaking time of an input pulse signal. CONSTITUTION:The discharge of a capacitor 5b of a charging/discharging circuit 5 is started from the breaking time of an input pulse signal (a) of a repeating frequency. When the terminal voltage is made lower than the threshold level VS of an inverter 4, the output of the inverter 4 is set at H to obtain a delay time DELTAt between the input and output pulse signals. A transistor 6 conducts when the signal (a) is changed to L from H, and the capacitor 5b is instantaneously set at voltage VP by a voltage source 8. Then the output of the inverter 4 is set at L. Hereafter this operation is repeated by the signal (a), and therefore an output pulse signal with which the fall of the signal (a) is delayed by DELTAt is obtained. Thus it is possible to obtain a delay circuit with which the delay time of the rise of input and output pulse signals is constant even though the repeating frequency of the signal (a) is approximate to the time constant CR of the circuit 5.

Abstract: PURPOSE:To shorten the starting and stopping times of a generator motor by coupling a thyristor starter to the motor at the stopping time, forming delay phase together with a position detector and a phase delay unit and supplying it to an armature. CONSTITUTION:When a generator motor 18 is stopped, a breaker 17 is opened to isolate it from a system, a thyristor starter 3 which has a power reactor 4 and a power inverter 6 is operated upon closure of a breaker 1, the position signal of a rotor detected by a position detector 13 is delayed by a phase delay unit 8 to produce a delay signal, which is applied to a power inverter controller 12, thereby controlling the power inverter 6. Then, a breaker 7 is closed to apply 3-phase AC to the armature coil roating in the delayed phase form the rotor. Accordingly, the rotor is pulled to the reverse revolving magnetic field to the rotating direction to roduce a braking torque, the speed is thus decelerated to stop the rotor, thereby safely braking it in a short time.
