Patent number: 8606243Abstract: A mobile network system includes a guidance message control server, a call control server and a plurality of access gateways. The call control server includes a gateway management section that determines an access gateway as a subject of call restriction, a first instructing section that transmits a message transmission instruction to the guidance message control server and a second instructing section that transmits a call restriction instruction to the access gateway. The guidance message control server includes a receiving section that receives the message transmission instruction, an acquisition section that acquires a guidance message data and a transmission section that transmits the guidance message data to a specified multicast group. Each of the access gateways includes a processing section that performs multicast group participation processing for participating in the specified multicast group and a guidance transmission section that transmits the guidance message data to a mobile terminal.Type: GrantFiled: December 15, 2009Date of Patent: December 10, 2013Assignee: Fujitsu LimitedInventors: Kazuyuki Ohtsu, Yuji Tajima, Takashi Mitsuhashi, Kohji Inokawa, Yumi Eguchi

Patent number: 8346269Abstract: A mobile network system includes a guidance message control server, a call control server and access gateways. The call control server receives a call request notification from a first access gateway, determines whether a second access gateway is connected to a second mobile terminal, transmits a message transmission instruction to the guidance message control server and transmits a response message including a same group specifying information. The guidance message control server receives the message transmission instruction from the call control server, acquires guidance message data specified by a message specifying information and multicast transmits the guidance message data to a multicast group specified by the group specifying information.Type: GrantFiled: December 15, 2009Date of Patent: January 1, 2013Assignee: Fujitsu LimitedInventors: Kazuyuki Ohtsu, Yuji Tajima, Takashi Mitsuhashi, Kohji Inokawa, Yumi Eguchi

Patent number: 7965776Abstract: The invention is directed to a technique for realtime processing of photographed pictures with less memory requirements. An image compressor compresses unit images, and so on of a given source picture individually. By converting reference data of compressed unit images and so on, the image compressor creates compressed data of the source picture. From the image compressor, a reference parameter generator receives original reference data corresponding to each unit image and so on having undergone the reference data conversion. An image decompressor retrieves a plurality of compressed unit images, and so on in an order suitable for a specified image editing operation. The image processor outputs the decompressed unit images after editing them to effect the specified image editing operation.Type: GrantFiled: February 6, 2006Date of Patent: June 21, 2011Assignee: Fujitsu Semiconductor LimitedInventors: Kenichiro Kuroki, Yuji Tajima, Nobutaka Yamagishi

Patent number: 7890101Abstract: An I-CSCF and an S-CSCF are included in a single call controlling apparatus. A message from a terminal directed to one of a plurality of degenerate-call controlling apparatuses. The I-CSCF in that apparatus receives the message and forwards the message to an S-CSCF that serves as the storing destination, which is specified for each subscriber in advance. The I-CSCF is configured to receive a message that has been forwarded from the same call controlling apparatus or another call controlling apparatus and to control sessions of the terminal based on the received messages.Type: GrantFiled: May 22, 2006Date of Patent: February 15, 2011Assignee: Fujitsu LimitedInventors: Keiichiro Yamakawa, Takashi Mitsuhashi, Yuji Tajima, Takehito Tsurumi, Takashi Kitano

Publication number: 20100115107Abstract: When a communication route is established between SIP servers #1 and #3, an SIP server #2 performing a relay between the servers #1 and #3 receives an INVITE signal from the SIP server #1, not describing track information about the SIP server #2 in a Via header and a Record-Route header of the INVITE signal, but transferring the signal to the SIP server #3. Thus, after the transferred INVITE signal, the signal transmitted and received by the SIP servers #1 and #3, does not include the track information about the SIP server #2, thereby transmitting the signal without passing through the SIP server #2.Type: ApplicationFiled: January 15, 2010Publication date: May 6, 2010Applicant: FUJITSU LIMITEDInventors: Takashi Mitsuhashi, Takashi Kitano, Kazuo Ohshima, Yuji Tajima

Publication number: 20070171231Abstract: A data buffer unit retains unit data sequentially decoded by a JPEG decoder. The data buffer unit has memory capacity equal to or larger than capacity required for storing unit data and smaller than capacity required for storing a screenful of image data on a display device. A data output control unit sequentially reads the unit data sequentially retained in the data buffer unit, and outputs the read unit data to the display device together with data indicating display positions on the display device. Thus, image data decoded by the JPEG decoder can be outputted to the display device without a frame buffer of large memory capacity. Accordingly, it is possible to reduce the cost for an image display controlling device which displays images on a display device.Type: ApplicationFiled: May 8, 2006Publication date: July 26, 2007Inventors: Atsushi Yamada, Yuji Tajima

Patent number: 6262379Abstract: A cover (32) is provided with a first and a second guide holes (32a, 32b) and an intermediate projection (33). A first and a second projections (34a, 35a) of a first and a second movable members (34, 35) are inserted into the first and the second guide holes (32a, 32b). On a back face of an operating knob (36) is provided a first guide part (37) into which the intermediate projection (33) is adapted to be inserted, a second and a third guide parts (38, 39) into which the first and the second projections (34a, 35a) are adapted to be inserted. When the first movable member (34) is moved in a direction of an arrow (A1) by an operation of the operating knob (36), a reclining switch (13) is actuated, and when the second movable member (35) is moved in a direction of an arrow (A2), a head restraint switch (14) is actuated.Type: GrantFiled: September 8, 2000Date of Patent: July 17, 2001Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventor: Yuji Tajima
