Patent number: 5132799Abstract: A PLL frquency synthesizer system television signal receiving apparatus includes a tuner, a control circuit for controlling a channel selecting operation by the tuner, and an intermediate frequency processing circuit for subjecting the IF signal outputted from the tuner to an intermediate frequency processing. The control circuit controls oscillating frequency of a local oscillating circuit in the tuner based on the PLL frequency synthesizer system. The intermediate frequency processing circuit includes an AFT signal detecting circuit for detecting a deviation of the IF signal frequency from the standard carrier frequency and feeding back the same to the control circuit. The AFT signal detecting circuit has an AFT coil which radiates higher harmonics. After a channel selection by the control circuit is completed, the AFT signal detecting circuit is rendered non-operative, so that beat interference appearing on a reproduced picture caused by the higher harmonics from the AFT coil are prevented.Type: GrantFiled: October 29, 1990Date of Patent: July 21, 1992Assignee: Sanyo Electric Co., Ltd.Inventor: Hiroki Gakumura

Patent number: 5132517Abstract: An electric glow element has a heating-conductor coiled band inside of a glow-coil dish, with a mechanically strong clamped connection between the coiled band and the glow-coil dish. The connection has good electrical conductivity, and is formed by a first bead in the glow-coil dish base wall and a side wall of the glow-coil dish which is concavely curved towards the inside of the dish. A second bead is formed outside of the first bead, and serves to clamp a band end of the heating-conductor coiled band firmly, fixing the heating-conductor coiled band end between the base wall and the side wall. In a second embodiment, a single bead connects the base wall and the curved side wall. The single bead extends below the plane of the base wall, and receives the second band end. The second band end extends out of the coil plane of the coil, and the glow coil is disposed in the interior of the glow coil dish and is oriented so as to have its coil plane generally parallel to the base wall.Type: GrantFiled: September 27, 1990Date of Patent: July 21, 1992Assignee: Schoeller & Co., Elektrotechnische Fabrik GmbH & Co.Inventors: Alexander Von Gaisberg, Norbert Graeser, Alfred Merkel

Patent number: 5132252Abstract: A method for preventing contamination caused by residues of etched off patterns etched by photolithographic etching. A considerable amount of small contamination spots on a semiconductor chip are found to be caused by tiny residues of etched off patterns. These residues are formed primarily around the periphery of device areas and mark patterns when their outsides are etched off. The occurence of such residues of etching is increased by anisotropic etching. These residues are dislodged by succeeding steps of the pattern making process, and disperse over the substrate causing small contamination spots. To avoid the detrimental effects of the etching residues, the edges of the mark patterns and device areas are covered with an edge cover which is formed in a step to following the pattern etching process.Type: GrantFiled: April 25, 1989Date of Patent: July 21, 1992Assignees: Fujitsu Limited, Kyushu Fujitsu Electronics LimitedInventors: Hidehiko Shiraiwa, Hisatsugu Shirai, Nobuhiro Takahashi, Shinichi Nomura

Patent number: 5131370Abstract: A system for controlling ignition timing of a vehicle internal combustion engine, in which a plurality of sets of ignition timing control characteristics are established in response to the octane numbers of different kinds of fuel which may intentionally or unintentionally be used in the vehicle. The system infers the octane number of the fuel being used from the occurrence state of knock and selects the set of control characteristics corresponding to the selected fuel octane number, whereafter it determines the ignition timing based on the selected set of control characteristics. The system overcomes the problem of unnecessarily reduced torque occurring when the set of characteristics for low octane number fuel is misselected when the vehicle is running on high octane number fuel, as may happen particularly at the time of engine cold start, since during warmup the engine is apt to produce mechanical noise resulting in spurious knock detection.Type: GrantFiled: July 29, 1991Date of Patent: July 21, 1992Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masataka Chikamatsu, Masaki Kanehiro

Patent number: 5131074Abstract: A knowledge compilation/pattern reasoning system has two subsystems: a pattern generating subsystem for interpreting human representation of knowledge and physical models and transforming them into pattern data, and an executing subsystem for analyzing states by using the generated pattern data and decision criterion data. An operation system of the kind adopting pattern type reasoning may be loaded with only the executing subsystem which uses pattern data compiled by the pattern generating subsystem beforehand, for the purpose of implementing high-speed execution. Since the transformation of human representation of knowledge and physical models into pattern data is effected by the pattern generating subsystem which is independent of the executing system, human representation of knowledge and physical models and pattern data are desirably interfaced to each other.Type: GrantFiled: October 2, 1989Date of Patent: July 14, 1992Assignee: Adin Research, Inc.Inventors: Ken Nakamura, Yohichi Ageishi, Ryuji Horikawa, Hidetoshi Yamaguchi

Patent number: 5130589Abstract: An apparatus for correcting imbalance of a rotor suspended by a magnetic bearing system including a displacement sensor for detecting a displacement of the rotor. An imbalance correcting circuit applies a trial imbalance correcting signal to the magnetic bearing system. A command computer applies an amount of correction to the imbalance correcting circuit and calculates an influence factor of the imbalance correcting signal on the basis of outputs from the displacement sensor before and after the imbalance correcting signal is applied to the magnetic bearing system, so as to cause the imbalance correcting circuit to apply a predetermined imbalance correcting signal produced from the influence factor to the magnetic bearing system, thereby minimizing the output of the displacement sensor to correct mass-imbalance of the rotor.Type: GrantFiled: March 12, 1991Date of Patent: July 14, 1992Assignee: Ebara CorporationInventor: Yoichi Kanemitsu
