Publication number: 20040157067Abstract: In a magnetic sensor (1) including a substrate (10) having a magnetism-sensitive element (11) formed thereon, a hard membrane (14) is formed on the outermost surface, an organic film (13) to relieve the stress caused by the hard membrane (14) is formed under the hard membrane (14), and an inorganic film (12) to relieve the stress caused by the organic film (13) is formed between the organic film (13) and magnetism-sensitive element (11). Also, an intermediate film formed from an element having a large force of bonding to carbon may be formed between the organic film (13) and hard membrane (14). Thus, the magnetic sensor (MR sensor, for example) can be protected against an external shock.Type: ApplicationFiled: October 20, 2003Publication date: August 12, 2004Applicant: Sony Precision Technology Inc.Inventors: Masaaki Kusumi, Mitsuru Ohno, Michio Okano, Hideki Nakamori, Touru Sumiya, Akitaka Tsunogae, Tomoyuki Nakada, Teruyuki Miura, Yoshihiko Ohkawara

Patent number: 6772088Abstract: A position transducer capable of accurately detecting an n-bit code by a small number of ABS detectors when there is provided one ABS track. In an ABS head, the ABS detectors 101 to 10n+m are disposed for a distance &lgr;1 between the first ABS detector 101 and (n+m)th ABS detector 10n+m to satisfy a requirement (n−1)&lgr;+2&dgr;<&lgr;1 and a distance &lgr;2 between two successive ones of the ABS detectors to satisfy a requirement 2&dgr;<&lgr;2<&lgr;−2&dgr;, so that at least one ABS detector is opposite to a stable area T in each of micro-areas at n successive bits.Type: GrantFiled: February 21, 2003Date of Patent: August 3, 2004Assignee: Sony Precision Technology Inc.Inventors: Yasuo Nekado, Michio Okano, Shigeru Ishimoto, Mitsuru Ohno, Masaaki Kusumi

Publication number: 20040065486Abstract: In a scale device including a case member (8) having a guide opening (9) formed therein, seal lip members (12A, 12B), a carrier unit (13) having seal lip pressing means (22, 23) formed thereon, and a coupling member (16) which slides inside and relative to the guide opening (9), the seal lip members (12A, 12B) are pressed at end portions (12e, 12f) thereof by the seal lip pressing means (22, 23) in the vicinity of opposite end portions (16b, 16c) of the coupling member (16) to prevent the seal lip members (12A, 12B) from being spread. Thus, any gaps can be prevented from taking place between the seal lip members (12A, 12B) and coupling member (16) in the vicinity of the opposite end portions (12e, 12f) of the latter. Therefore, dust or the like can be prevented from entering the case member (8).Type: ApplicationFiled: September 29, 2003Publication date: April 8, 2004Applicant: Sony Precision Technology Inc.Inventors: Gunichi Nakamura, Mitsuru Ohno

Patent number: 6693565Abstract: There is provided a position transducer (1) capable of accurately detecting an n-bit code by n ABS detectors from one ABS track. When an INC value is under j or over k, signal output from each of the ABS detectors is binarized based on a threshold h and also based on a threshold l. First, an ABS value decider (24) decides that a bit is “H” when it has been judged as being “H” on the basis of both the thresholds and a bit is “L” when it is has been judged as being “L” on the basis of both the thresholds. When the INC value is under j, a lower bit has the same code as that of the deiced bit. So, the ABS value decider (24) decides that the lower bit is “H” or “L”. On the other hand, when the INC value is over k, an upper bit has the same code as the decided code. Thus, the ABS value decider (24) decides that the upper bit is “H” or “L”.Type: GrantFiled: February 21, 2003Date of Patent: February 17, 2004Assignee: Sony Precision Technology Inc.Inventors: Masaaki Kusumi, Michio Okano, Shigeru Ishimoto, Mitsuru Ohno, Yasuo Nekado

Patent number: 5405986Abstract: A catalyst for synthesizing a carbonic diester includes at least one copper compound selected from among copper oxides, copper hydroxides, a salt of copper with a weak acid consisting of the elements other than halogen such as copper borates, and complexes or complex salts consisting of the elements other than halogen and formed with copper or a copper compound a and ligand. The catalyst has a high activity, a high reaction selectivity and excellent stability with a minimal risk of corroding equipment. The catalyst can include, as a co-catalyst component, a platinum-group metal such as palladium or a halogen-free platinum-group metal compound such as palladium acetate. The catalyst component may be supported on a carrier, for example, an activated carbon. A carbonic diester is advantageously produced by allowing an alcohol to react with carbon monoxide and oxygen in the presence of the catalyst.Type: GrantFiled: January 24, 1994Date of Patent: April 11, 1995Assignee: Daicel Chemical Industries, Ltd.Inventors: Shingo Oda, Mitsuru Ohno

Patent number: 4649648Abstract: A linear scale features a removable scale channel and adjustable head assembly for easy, accurate, permanent positioning on a machine tool bed or other mobile device. The scale channel, and a matching positioning tool, has balls at opposite ends engaging a socketed mounting bracket. When in use, the flexible socket coupling is clamped into immobility by removable covers over open faces of the mounting brackets. During installation, the mounting brackets engage the positioning tool rather than the scale channel and with the flexible-socket couplings free to gimbal. The mounting brackets are fixed to the machine tool at a fixed axial spacing determined by the length of the positioning tool but at whatever angular attitude best suits the supporting surface of the machine tool. The positioning tool is then removed and replaced by the scale channel. The head assembly is fixed to a stationary stand opposite the scale channel.Type: GrantFiled: August 28, 1985Date of Patent: March 17, 1987Assignee: Sony Magnescale IncorporationInventors: Kazuo Nagaoka, Tomoichi Isobe, Toshihiko Kanasugi, Nobuyuki Suzuki, Sadao Wakabayashi, Kenji Uchida, Hideharu Tsukamoto, Mitsuru Ohno, Tadahiko Shimano
