  • Patent number: 7294035
    Abstract: A method of secondarily welding one end of a shroud glass tube covering an arc tube body having a discharge emitting portion, having the other end welded primarily to one of the arc tube body ends, to the other end side of the arc tube body, while discharging air from, and introducing an inactive gas into, the tube through the opening end of the glass tube to hold a negative pressure. Heating and melting from a side is carried out. The opening end of the glass tube is connected to a piping passage component for discharging air and introducing an inactive gas through a rotatable magnetic fluid seal unit. Secondary welding is carried out with the rotation of the glass tube around an axis. The glass tube rotated with respect to secondary side heater is uniformly heated, molten and softened circumferentially, and welded along the arc tube body outer periphery.

  • Patent number: 6615313
    Abstract: An input/output control device uses all of its cache memory effectively and allows cache memory modules to be added in increments of one. When cache memory included in the input/output control device is operating normally and the input/output control device receives a write request from a processing device, the input/output control device returns a write request completed response after writing data to cache memory as set forth in configuration information included in the input/output control device. The write data in the cache memory is then written to one or more disk devices asynchronously with the write completed response. When there is a problem with a cache memory module, the write data that was to be written to the region controlled by the cache memory module where the problem occurred is divided among the remaining cache memory modules.

  • Publication number: 20030048837
    Abstract: During communications between a station apparatus and home apparatus, the station apparatus transmits a test signal TS, the home apparatus having received the test signal recognizes a change in state of a metallic transmission channel in the middle of the communications, estimates an output level suitable for a current state, and requests the station apparatus to transmit data with an estimated output level using a test signal NS, and the station apparatus transmits data with the output level requested from the home apparatus, and thus changes a transmission level set at the time of starting communications to a level corresponding to the change in state.

  • Patent number: 6360296
    Abstract: File control apparatus adapted to be operatively connected to a host device for controlling a plurality of memory devices includes a cache memory for storing data blocks sent to or retrieved from the at least one memory device by the host. A control unit controls data transfer between the memory devices and the cache memory. A continuous data information generating device is included for generating continuous data information indicating whether the data blocks from the same memory device are updated continuously The control unit stores the continuously updated data blocks from the same memory device back to that same memory device as a single data block in accordance with a least recently used (LRU) scheme.
