Patent number: 6442146Abstract: The present invention is directed to a TDMA communication system which is adapted to different communication environments or prepares different communication environments and allows each mobile station to be set for working in any one of the different communication environments. The communication system commonly uses a TDMA format that has a fixed frame-length and a constant number of bits for each of the slots composing the frame. The communication environments have prepared respective sets of communication conditions, each set including a transmission power, a modulating method, the number of multiplexed signals, error-correction, an antenna gain, a frequency hopping value and a diversity value. At each mobile station and each base station, one of plural sets of communication conditions for respective environments is selected to establish communication with each other under the selected environment.Type: GrantFiled: May 11, 1998Date of Patent: August 27, 2002Assignees: Sharp Kabushiki Kaisha, Hitachi Ltd., Mitsubishi Denki Kabushiki Kaisha, Communication Research Laboratory, Ministry of Posts and Telecommunications, Nippon Telegraph And Telephone Corporation, NTT Mobile Communications Network, Inc., YRP Mobile Telecommunications Key Technology Research Laboratories Co.

Patent number: 5803517Abstract: A vehicular bumper beam is comprised of a hollow member of high tension steel, which has a front corner portion with an inclined surface. With this arrangement, when a collision energy is applied obliquely to the corner portion of the bumper beam, the collision energy is received by the inclined surface. As a result, a small collision energy arising from a collision at a low speed can readily be absorbed while a large collision energy arising from a collision at a high speed can be transmitted to a vehicle body quickly and efficiently.Type: GrantFiled: June 27, 1996Date of Patent: September 8, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Akihiro Shibuya

Patent number: 5803514Abstract: A structure for mounting a bumper beam 2 extending transversely of a vehicle covered with a bumper face 6 and mounted to a chassis 3 through a support 4, in which the bumper beam 2 is formed into a hollow body made of high-tension steel, the front end of the support 4 extends forward beyond the rear portion of the bumper beam 2. Thus, when a large collision energy works on the lightweight bumper beam formed into a hollow body made of high-tension steel, the collision energy is quickly transferred to the vehicle chassis through the front end of the beam.Type: GrantFiled: July 17, 1997Date of Patent: September 8, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Akihiro Shibuya, Kouji Yamada, Yoshinobu Kanazawa
