Patent number: 7294035Abstract: 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.Type: GrantFiled: May 9, 2005Date of Patent: November 13, 2007Assignee: Koito Manufacturing Co., Ltd.Inventors: Masayasu Hirata, Hiromi Kubota, Shinya Misonou

Patent number: 6615313Abstract: 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.Type: GrantFiled: February 9, 2001Date of Patent: September 2, 2003Assignee: Fujitsu LimitedInventors: Tadaomi Kato, Hideaki Omura, Hiromi Kubota
