Patent number: 7418777Abstract: A method of manufacturing a spin valve film, produces a large read out signal. After a completion of a film making process for forming a previous film of two films to be formed successively, but before an initiation of a film making process for forming a succeeding film of the two films, a step of decreasing an anisotropic magnetic field of the spin valve film is introduced by interrupting a film making process. This step may be performed by keeping a substrate within a sputtering vacuum chamber. The interruption can be shortened by exposing the substrate to a plasma, transferring the substrate in a separate vacuum chamber is lower or whose H2O or O2 concentration is higher than that in the sputtering vacuum chamber, conducting a surface treatment with a gas containing H2O or O2, or flowing a process gas.Type: GrantFiled: May 5, 2005Date of Patent: September 2, 2008Assignee: TDK CorporationInventors: Hajime Amano, Hiroaki Takezutsumi, Tetsuro Sasaki, Jun-ichi Sato

Patent number: 6353316Abstract: A magnetoresistive film through which a sense current for detecting a resistance change due to a magnetic field to be detected flows in a longitudinal direction, and a lateral bias film which is magnetized in a fixed direction by a constant magnitude such that a lateral bias is applied to said magnetoresistive film in a lateral direction intersecting said longitudinal direction are arranged to be opposed to each other via a magnetic isolation film. By conducting said sense current by means of a pair of lead conductive films coupled electrically to both edges of said magnetoresistive film, a magnetization recorded on a magnetic record medium can be detected. Since the lateral bias is applied to the magnetoresistive film such that the lateral bias is not affected by the sense current and external magnetic fields, the magnetization of the magnetic record medium can be stably detected without being influenced by the sense current and external magnetic fields.Type: GrantFiled: June 17, 1999Date of Patent: March 5, 2002Assignee: TDK CorporationInventor: Hajime Amano

Patent number: 5850191Abstract: A moving vehicle specification system having an auxiliary specification function. If a vehicle could not be specified by a local controller, the license plate number is decoded from a license plate image in a method where a number database is referenced according to grouped information and number information is retrieved. Auxiliary specification of the vehicle is performed through a comparison between the searched result and the decoded result. This prevents any impairment in the real-time performance of the processing based on local controller and permits more accurate vehicle specification.Type: GrantFiled: December 11, 1996Date of Patent: December 15, 1998Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koichi Yagi, Hajime Amano

Patent number: 5602375Abstract: An automatic debiting system and method suitable for free lane traveling. Debiting antennas disposed on a first gantry are used to communicate with an in-vehicle unit (IU) mounted on the vehicle for debiting. The passages of the vehicles are detected by the loop coils or line scanners, and the license plates, etc., of the vehicles are photographed by the enforcement cameras. Debiting confirmation antennas on second gantry are used to communicate with the IU for the confirmation of debiting. When the normal debiting is confirmed, a local controller informs a system central controller of the fact, whereas when abnormal debiting is confirmed, images of the license plate, etc., of the illegal vehicle are transmitted to the system central controller as illegal vehicle images. The debiting is thus possible at the time of free lane traveling.Type: GrantFiled: June 11, 1996Date of Patent: February 11, 1997Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shuichi Sunahara, Souichi Ishikawa, Takehiko Okuda, Hajime Amano, Kouichi Yagi, Masanori Omae
