Abstract: PURPOSE:To remelt and chill a cam surface without causing no shoulder sag at the lateral ends of the cam surface by forming recessed grooved parts at both lateral ends of the cam surface of a camshaft stock made of cast iron and then remelting the cam surface by means of high energy beam. CONSTITUTION:A camshaft stock 1 is cast from cast iron and skin on a cam surface 2 is removed, and then, a recessed grooved part 3 is formed at the position within a prescribed distance (a) from both lateral ends of the cam surface 2, from a cam top part 21a to a cam circle part 21b.

Abstract: PURPOSE:To prevent stress to a motor by providing a phase-locked oscillation-loop circuit, providing parallel-operation period of inverter-voltage operation and line- voltage operation in the case the power supply is switched from the inverter to the commercial power line. CONSTITUTION:When an inverter is actuated and the lower limit of a synchronization switching frequency domain is reached, a signal is outputted from a frequency- synchronization detecting circuit 29. Then, a phase-synchronization detecting circuit 28 begins to operate and chacking is performed with regard to the output of a phase- locked oscillation-loop circuit 21 whose phase and frequency are synchronized with a line power supply in the standby status. When the synchronization has been achieved, CTT2 is turned on through a delay circuit 30, and the inverter and the line power supply are parallelly operated. After the specified period, switching to the line poer supply is made by turning CTT1 off. Therefore, the parallel operation can be performed with the frequencies, phases, and voltages being coincided, and the switching can be accomplished, thereby the stress which might be applied to the motor and the inverter can be eliminated.

Title: Power conversion device for rolling stock
Inventor: HENMI TAKUMA
IPC: B60L3/00
Filed: 1989-02-28
Abstract: PURPOSE:To prevent resonance phenomenon by dividing a DC filter reactor into two by additionally providing a resistor to one of the bisected reactors in parallel and by doing away with a limiting resistor. CONSTITUTION:When a resistor 4 is connected to a DC filter reactor 3 in parallel, the steady-state input current unrelated to resonance flows to the reactor for the most part, and for the resonance current component the current at the voltage across the DC filter reactor 3 flows to the parallel resistor 4. The resonance frequency component can thereby go through this DC filter. Because of the voltage across the resistor 4, if L is reduced, so will it be with the current. By dividing a DC filter reactor and by connecting a resistor to one of the split reactors in parallel, the capacity of the resistor 4 can be reduced. The resonance phenomenon can thereby be prevented and the efficiency of an inverter device can be improved.

Filed: 1982-03-19
Abstract: PURPOSE:To prevent a malfunction, by inhibiting the start of charging until the potential of the discharging mode becomes lower than a prescribed level for a capacitor which controls a latch relay functioning as a control means by the charging and discharging of said capacitor. CONSTITUTION:Transistors (TR) 38 and 37 are turned on and off respectively in case the temperature of a heater 2 is lower than that set by a volume 35 with the resistance of a thermistor 41 set at a high level. Thus VC of the TR37 becomes high, and the TRs 27 and 24 are turned off and on respectively with TRs 4 and 15 turned on. Then a TR8 is turned off, and a charging current flows instantaneously to a capacitor 7 to drive a latch relay coil 3B. Thus a contact 3A is closed and latched. The heater 2 conducts to raise temperature, and the state of each part is inverted. The capacitor 7 discharges and releases the latching. The temperature of the thermistor 41 drops to increase the resistance and then VB of the TR38. The feedback is carried out to the base of the TR37 with ON of the TR27 via a diode 29 and a resistance 32. The conduction is inhibited until the temperature is set lower than the level of the OFF mode. Then the hysteresis is drawn.
