摘要:
A circuit breaker comprising a vacuum valve; an electromagnet including a first coil for driving an operating shaft of the vacuum valve toward an opening direction by electromagnetic repulsion, a movable core and a permanent magnet; and an operating mechanism which excites the first coil to close the vacuum valve, holds the vacuum valve closed by an attractive force of the permanent magnet and excites the first coil in a direction reverse to an excitation direction in closing operation to open the vacuum valve. In the circuit breaker, together with the first coil, a second coil which is excited simultaneously with an electromagnetic repulsion coil for electromagnetic repulsion in quick opening operation by electromagnetic repulsion is provided in the electromagnet.

A tracked vehicle has a power control apparatus for controlling charging and discharging of a plurality of storage devices. A voltage measuring device measures voltages of the respective storage devices, and a current measuring device measures currents flowing through the respective storage devices. A status detecting device detects the operating status of each storage device based on values measured by the voltage and current measuring devices; and a charging/discharging controlling device controls currents, voltages, or power according to the operating status of each storage device detected by the status detecting device, to charge or discharge the storage devices.

Sheets fed out from a sheet feeding portion, which is brought into pressure contact with the sheets by the upward movement of a sheet stacking portion to feed out the sheets, are separated and conveyed one by one while being upwardly curved. During the sheet feeding operation, the sheet stacking portion is sequentially moved up, and when the sheet feeding operation is completed, the sheet stacking portion is moved down. Further, a remaining amount indicating member moved with the upward movement of the sheet stacking portion to indicate the remaining amount of sheets is held at a position before the sheet stacking portion is moved down, by a holding mechanism, when the sheet feeding operation is completed and the sheet stacking portion is moved down.

When changes occur in an environment of the service user terminal, a network operator terminal acquires hashed environment information indicative of the changes from the service user terminal. The network operator terminal sends the hashed environment information to an environment management authority terminal. The environment management authority terminal calculates an evaluation value based on the hashed environment information and transmits the evaluation value to a network operator terminal. The network operator terminal transmits status change information to the service provider terminal. The service provider terminal updates information about the user information previously stored and decides whether to provide the service to the service user terminal based on the updated information.

An ink bag comprises a flexible bag body of a generally rectangular form and a holding member attached to one edge of the bag body, wherein the holding member includes: an ink filling opening for filling the bag body with ink; an ink discharging opening for discharging the ink inside the bag body; and an engaging part for holding the ink bag to a cartridge case in which the ink bag is accommodated.
摘要:
An SZ (size information) section is provided for each of registers that make up a register file. Suppose an instruction decoded requests that operand data of a particular size be loaded from a RAM into the register file or that immediate operand data of a particular size be transferred to the register file. Then, the size information of the operand data will be retained in the SZ section. The instruction decoded may also be an arithmetic and logical operation instruction requesting that operand data in the register file be referred to or an instruction requesting that the operand data be stored from the register file into the RAM. In such a case, the size information will be read out from the SZ section of the register file and only parts of various components constituting manipulation means (like ALU), which have been specified by the size information, will be enabled. As a result, the power, which is usually dissipated by a processor handling data of multiple sizes, can be cut down effectively.
摘要:
An air damper consists of a tubular cylinder with opposite ends, a piston movable in the cylinder, a first coil spring for resiliently biasing the piston in the direction of one end of the cylinder, a string for transferring dampening effect produced by a motion of the piston to an openable object, a shaft with a flange slidably fitted into the piston and a second coil spring interposed between the flange of the shaft and the piston inside the first coil spring. The second coil spring exerts a resilient biasing force at later stages of the motion of the piston in the direction of the other end of the tubular cylinder.
