Patent number: 7472425Abstract: A service provider makes requests to an information processing center for processing for an IC card in card command units. The information processing center issues encrypted card commands that can be interpreted by the IC card itself based on requests received from the service provider and sends these to the IC card via the computer network, client, and card reader/writer device. This enables an IC card connected to a client to be accessed using secure communication.Type: GrantFiled: April 4, 2003Date of Patent: December 30, 2008Assignee: Sony CorporationInventors: Mitsushige Suzuki, Junichi Sato, Takashi Matsuo

Patent number: 7142151Abstract: In order to magnetically shield the transmission line which connects the external connector mounted on the outer housing with the internal circuit and also to make it possible to freely mount the external connector without being limited by the position of the internal circuit, an outer housing 60 consists of an outer housing main body 61 and a shielding layer 62 applied to the inner-periphery surface of the outer housing 60. An transmission line 73 extends from the internal circuit through the outer-periphery side of the shielding layer 62 of the outer housing 60 along the shielding layer 62 to the desired position, where the external connector 70 is placed.Type: GrantFiled: March 10, 2005Date of Patent: November 28, 2006Assignee: Hitachi, Ltd.Inventors: Mitsushige Suzuki, Kazuaki Takano, Ryuji Fukute

Patent number: 7126525Abstract: A millimeter-wave radar has a radome or radar cover including a layer, the dielectric constant of which is a greater than that of the other portion without the layer, or including a magnetic loss layer in an appropriate position with respect to the antenna. The dielectric constant of the radome or radar cover can be made higher in a portion corresponding to the side of the antenna than in a portion corresponding to the front of the antenna.Type: GrantFiled: February 24, 2004Date of Patent: October 24, 2006Assignees: Hitachi, Ltd., Hitachi Car Engineering Co., Ltd.Inventors: Mitsushige Suzuki, Kazuaki Takano

Patent number: 6937184Abstract: A millimeter wave radar for the purpose of automatic operation or collision prevention of a vehicle which solves the problem that a side lobe of a transmitted electromagnetic wave is reflected by surrounding bodies and the reflected wave is received, with the result that unnecessary bodies may also be detected. A layer higher in dielectric loss than a radome or a magnetic loss layer and a conductor layer in a mesh form are embedded in a part of the inside surface of the radome, whereby it is possible to provide a millimeter wave radar which is light in weight, excellent in weathering performance, inexpensive, and excellent in detection performance.Type: GrantFiled: March 19, 2003Date of Patent: August 30, 2005Assignee: Hitachi, Ltd.Inventors: Tadashi Fujieda, Hiroshi Kuroda, Terumi Nakazawa, Mitsushige Suzuki
