摘要:
A wire electric discharge machining apparatus is provided to equip with an automatic wire threader more reliably threading a wire electrode through an start hole. The wire electric discharge machining apparatus includes an automatic wire threader including: a feed roller disposed higher than the start hole and feeding a wire electrode toward the start hole; and a vertical drive device disposed between the feed roller and the start hole, and supplying compressed air in the upward and downward directions to vertically move the wire electrode slightly. The vertical drive device includes wire guides having guide holes through which the wire electrode is passed. The wire guides are constructed so that upward movement by the compressed air is possible.

When the ignition switch of a vehicle is turned OFF, a purging process for increasing the flow of an off-gas fluidizing in each of the outlet side pipings of a fuel cell and discharging water remaining in a fuel cell system to an outside is started to be executed, and the amount of current conductance to the heater of the gas sensor is increased synchronously with the start of the execution of the purging process. With the completion of the purging process, the fluidization of the off-gas in each of the outlet side pipings stops, and the amount of current conductance to each of the units of the gas sensor (for example, an electrifying voltage) is gradually decreased depending on a predetermined current conductance reducing amount which is preset, thereby stopping the current conductance to each of the units and the amount of current conductance to the heater is gradually decreased, thereby stopping the current conductance to the heater.

摘要:
Arbitrary data is read out from a main storage device, based on a permanent fault detection address that is used to detect a permanent fault on an address line. A bit error in the permanent fault detection address is detected and corrected, based on an error correcting code included in the arbitrary data read out. A permanent fault on the address line is determined, based on results of the error detection/correction.
