摘要:
A DC switchgear is provided with a commutation-type DC circuit breaker having a main circuit provided with a main switch for interconnecting a DC power supply and a load, and a commutating circuit provided with a commutating capacitor and a commutating switch, which is connected electrically parallel to the main switch. The switchgear further has a DC circuit breaker accommodating box that includes the main circuit provided with the main switch, and the commutation-type DC circuit breaker; a front accommodating box disposed on the front of the DC circuit breaker accommodating box, which accommodates devices having functions for controlling the switchgear and indicating a status, such as a failure status thereof; and a rear accommodating box disposed on the back of the DC circuit breaker accommodating box. The front and rear accommodating boxes are connected to the DC circuit breaker accommodating box to form an integrated DC switchgear.
摘要:
A commutation type DC breaker comprising a main switch inserted in series into a main circuit for connecting a DC source and a load, a commutation capacitor, a reactor, and a commutation switch for supplying charges stored in the commutation capacitor to the main switch in an opposite direction to a main circuit current, producing a current zero point, thereby breaking the main switch, characterized in that the commutation capacitor, the reactor, and the commutation switch which are composed a commutation circuit and a control circuit for controlling the turning on or off of the main switch and the commutation switch are loaded on a frame with the main switch loaded.

A leisure vehicle including a plurality of communication devices built into a vehicle body of the leisure vehicle; and a multiplex communication line through which the plurality of communication devices are coupled to each other. The communication devices are configured to perform multiplexed data communication through the multiplex communication line. The multiplex communication line is positioned a distance apart from a noise source mounted in the vehicle body so as not to be subjected to a noise.
摘要:
A method for the computation of a system processing time in performing an operation in a system which can process a plurality of lots in a continuous or parallel manner, wherein the processing time of an object lot is computed based on the minimum processing time S0 for the object lot, the contents of the operation of a lot which is currently being processed, and the actual processing time of a lot, for which the operation has recently been completed.
摘要:
A method of controlling an engine for a vehicle including increasing an amount of air taken into the engine to an amount larger than an idling air amount corresponding an idling engine speed, when an engine speed of the engine is predetermined value or more, a throttle valve for controlling the amount of air taken into the engine has not been operated to be opened, and a clutch is in an off-state not to permit transmission of a drive force from the engine to a running drive element of the vehicle.
摘要:
A method of feeding fuel to an engine, comprising the steps of determining whether or not the engine is decelerating based on a time-lapse change rate of an engine speed of the engine, and reducing an amount of the fuel to be fed to air taken into the engine from outside to less than a reference amount preset according to the engine speed when it is determined that the engine is decelerating.

摘要:
A theft prevention apparatus of a leisure vehicle equipped with a rider's seat which opens outside is disclosed. The theft prevention apparatus typically includes a portable transmitter configured to transmit a user identification code by radio at predetermined intervals during travel of the vehicle, a vehicle receiver mounted in the vehicle and configured to receive the user identification code which is transmitted by radio from the portable transmitter, a controller coupled to the vehicle receiver through a signal line or by radio, and an alarm device mounted in the vehicle and configured to indicate an alarm to inform the rider that the portable transmitter has been lost, wherein the controller is configured to determine whether or not the vehicle receiver has received the user identification code transmitted from the transmitter within a predetermined time during travel of the vehicle, and to execute control to cause the alarm device to indicate the alarm when the controller determines that the receiver does not receive the user identification code within the predetermined time.
