Publication number: 20050231096Abstract: An electron device such as a fluorescent display tube is provided, wherein a simple ring-less getter can be simply fixed and arranged with a large degree of freedom. The ring-less getter, G11 to G13, is securely fixed to the inner surface of the glass anode substrate 111, using laser beams. The laser beam is irradiated onto the ring-less getter, G11 to G13, from outside the anode substrate 111. Thus, the laser beam passes through the anode substrate 111, thus heating and melting the ring-less getter, G11 to G13. The corresponding inner surface of the anode substrate 111 is melted trough the heating. In cooling, the portion where the ring-less getter, G11 to G13, and the anode substrate 111 are in a molten state is solidified, so that the ring-less getter, G11 to G13, is bonded to the anode substrate 111. The ring-less getter, G11 to G13, is shaped arbitrarily through press-working a getter material.Type: ApplicationFiled: May 8, 2003Publication date: October 20, 2005Inventors: Shogo Ishige, Yoshihisa Yonezawa, Yukio Ogawa

Patent number: 6939114Abstract: A dynamotor capable of operating as either a motor or a generator is used with both the armature portion and the field portion thereof capable of being rotated. In the case where a pulley operatively interlocked with the output shaft of the prime mover is mounted on the rotary shaft of the armature portion, the drive shaft of the compressor is mounted on the rotating field portion. Once the dynamotor is operated in motor mode, the rotational speed of the compressor is increased to the sum of the input rotational speed and the rotational speed of the dynamotor. The compressor is stopped by disconnecting a power feed circuit. When the input rotational speed is too high, the dynamotor is operated in generator mode. In this way, the rotational speed is reduced in accordance with the generated electric energy.Type: GrantFiled: October 23, 2003Date of Patent: September 6, 2005Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Shigeki Iwanami, Yukio Ogawa, Takashi Inoue, Hironori Asa

Patent number: 6918266Abstract: In an ejector, a nozzle is provided within a housing to defining a passage portion around the nozzle, and a suction port is provided in the housing to draw a refrigerant by entrainment of a driving refrigerant jetted from the nozzle. Further, a wall portion is provided in the housing such that the refrigerant drawn from the suction port into the passage portion is prevented from flowing toward an inlet side of the nozzle from a position of the suction port in an axial direction of the nozzle. Therefore, all of the refrigerant flowing from the suction port flows toward an outlet side of the nozzle without flowing toward the inlet side of the nozzle from the position of the suction port in the axial direction. Thus, it can prevent a large pressure loss from being caused in the refrigerant sucked from the suction port, and ejector efficiency can be effectively increased.Type: GrantFiled: April 16, 2004Date of Patent: July 19, 2005Assignee: DENSO CorporationInventors: Makoto Ikegami, Haruyuki Nishijima, Tooru Ikemoto, Yukio Ogawa, Hisatsugu Matsunaga, Takeharu Asaoka, Hirotsugu Takeuchi

Publication number: 20050138626Abstract: The request from the client to the server is made through the traffic control apparatus. The traffic control apparatus includes a unit for controlling the request from the client, a unit for judging the data reception performance of the client and a unit for controlling the number of clients simultaneously connected to the server. The number of simultaneous connections in the server is controlled so that the resource of the server can be utilized sufficiently and the requests in number exceeding the performance of the server cannot be transferred. When it is expected that it takes time longer than a fixed time to provide the service to be required to the client, the request is rejected and when it is expected that the service can be provided within the fixed time, the request is received.Type: ApplicationFiled: March 11, 2004Publication date: June 23, 2005Inventors: Akihisa Nagami, Yukio Ogawa, Masahiko Nakahara, Daisuke Yokota, Atsushi Ueoka

Publication number: 20040260821Abstract: System, method and program product performed by a proxy server which forwards an access request from a client to a data server and forwards response data from the data server to the client. A first address location and an encoding format of the response data are stored. A subsequent access request from the client which includes a second address location encoded by the encoding format is received. The second address location is compared to the first address location to determine if the second address location is related to the first address location. In response to a determination that the second address location is related to the first address location, the second address location is decoded based on the encoding format. The data server can be a web server, the response data can be a web page, and the second address location can include the first address.

Patent number: 6830438Abstract: A controlled compressor apparatus enables a hybrid compressor in an idle-stopping vehicle to operate more efficiently when driven by a motor alone. The controlled compressor apparatus includes a compressor 110, included in a refrigeration circuit 200, of a variable volume type for compressing a refrigerant; a motor 120 powered by a battery 12 to operate; and a controller 130 for selecting the driving force provided either by the engine 10 or the motor 120 to drive the compressor 110 and control its discharge volume. The controller 130 causes the motor 120 to operate the compressor 110 such that the compressor 110 is turned on or off at a discharge volume of the compressor 110 that larger within a variable range than that required for operating the refrigeration circuit 200.Type: GrantFiled: October 4, 2002Date of Patent: December 14, 2004Assignees: Nippon Soken, Inc., Denso CorporationInventors: Shigeki Iwanami, Yukio Ogawa, Yoshiki Tada

Patent number: 6717350Abstract: An electron tube such as a fluorescent display tube is provided. Auxiliary linear support members (e.g. linear spacers and linear dampers), which subsidiarily support liner members (e.g. cathode filaments and wire grids), are bonded on a substrate, using ultrasonic welding (without using an adhesive agent (e.g. fritted glass or a conductive paste)). A metal layer (e.g. a thin or thick aluminum film) is formed over the glass substrate. The end of the coil of a cathode filament is securely bonded to the metal layer. A spacer of a metal wire (e.g. aluminum) is ultrasonic welded to the metal layer. The welding is performed with the wedge tool of an ultrasonic welder placed at the position where the spacer is in contact with the cathode filament. A U-shaped recess is left at the welded spot. This recess prevents the cathode filament from being displaced. If necessary, the metal layer is formed over the substrate and the damper of a metal wire (e.g.Type: GrantFiled: March 1, 2002Date of Patent: April 6, 2004Assignee: Futaba CorporationInventors: Yoshihisa Yonezawa, Yukio Ogawa, Yasuhiro Nohara, Hiroaki Kawasaki
