Title: Controlling method for slewing of oil-pressure shovel
Inventor: YOSHIMATSU HIDEAKI
IPC: E02F9/22
Filed: 1982-02-10
Abstract: PURPOSE:To prevent the rocking and returning in the reverse diretion as well as smoothen the stopping of an oil-pressure shovel by a method in which the motor is decelerated at the time of deceleration and stoppage of turning of the shovel under a condition that the effluent oil amounts of the slewing motor is decreased in such a way as to lessen the holding torque of the motor. CONSTITUTION:The opening of a returning direction control valve 7 is controlled in a meter-out manner of a slewing motor 4 by reducing the area on the meter- out side, as shown by the line B basically. In this case, the curve C stands for a change in the opening area of an unload path. When a spool 11 is returned to neutral and the slewing motor 4 is decelerated and stopped, the opening area on the meter-out side is reduced by a notch 11g at the point B2 before closing the meter-out side. Then, the meter-in side is closed at the point A1 and then the meter-out side is closed at the point B1, and furthermore, both the meter-out side and the meter-in side are completely closed at the neutral position of the spool.

IPC: H02M3/155
Filed: 1980-02-22
Abstract: PURPOSE:To prevent the destruction of switching transistor and diode due to excessive current, by providing a current limit circuit with a switching transistor. CONSTITUTION:A resistance R5 is connected between the emitter of a transistor Q3 and the smoothing circuit, and two diodes D2, D3 are connected at the cross point between the base of the transistor Q3, resistor R5 and smoothing circuit.

Abstract: PURPOSE:To make it possible to increase the heat absorption quantity of an evaporator by making a high boiling point liquid coolant of a high temperature within a tower bottom storage apparatus exchange heat with a sucked gas of a main circuit in an auxiliary heat exchanger, and thereafter allowing the coolant to flow into the inlet port of the evaporator. CONSTITUTION:Changeover to a 'no separation' mode is carried out by turning a heater 18 off, closing a switching valve 17 and opening a switching valve 20. Then, since a high- boiling-point liquid coolant of a high temperature within a storage apparatus 19 flows into a main circuit via the switching valve 20, and auxiliary heat exchanger 15 and a second throttling device 21, the main circuit is operated as the coolant is in a composition of a mixed coolant affluent in a high-boiling-point coolant in a sealed state. The high-boiling-point liquid coolant of a high temperature within the storage apparatus 19 exchanges heat with a low-temperature gaseous coolant sent out from an evaporation 14 of the main circuit, whereby the liquid coolant is cooled, and further is throttled up to a low pressure by a second throttling device 21 and thereafter is joined with the main circuit and flows into the evaporator 14. For this reason, the enthalpy of the high temperature liquid coolant reduces, and the heat absorption quantity obtained in the evaporator 14 increases. Further, since the sucked gas is heated, the enthalpy thereof increases, and it is possible to sufficiently increase the heat radiation quantity on the utilization side.

Inventor: KANAI TAKEO
IPC: G05F1/70
Filed: 1993-02-09
Abstract: PURPOSE:To obtain a reactive-power compensation apparatus which has a small loss even in a standby state and a high efficiency by a method wherein a circuit breaker for a charging circuit is not released in a state that a circuit breaker, for system linkage, which links a self-excited converter to a system has been closed. CONSTITUTION:Even after a circuit breaker 10 for linkage to a system has been closed, a circuit breaker 24 for a charging circuit is not released and it is set to an ON state. In addition, a voltage in the charging circuit is set to the lower limit of a rated operating range for a DC voltage. Consequently, even when a voltage in a DC capacitor 13 is dropped, the circuit breaker 24 for the charging circuit is set to a closed state. As a result, electric power is supplied from the charging circuit, and the voltage in the DC capacitor 13 is maintained at a prescribed value. As a result, it is not required to charge the DC capacitor 13 by operating a self-excited converter 12. It is sufficient that the charging circuit supplies electric power by only the discharged portion of the DC capacitor 13, and a loss which is more than it is not required. In addition, when a standby state is shifted to the output operation of reactive power, it is not required to charge the DC capacitor 13 and the standby state can be shifted immediately to the output operation.
