Title: Retriever for information track
Inventor: TANEMURA TAKASHI
IPC: G11B21/08
Filed: 1994-03-30
Abstract: PURPOSE:To obtain a stable tracking control with limited following residue by detecting a groove traversing speed of a head to apply multi-stage acceleration or deceleration to a galvano-mirror so that the speed detected follows a specified target value. CONSTITUTION:Photodetectors 11 and 12 detect track errors and a galvanomirror 5 is driven so as to eliminate deviation of operating position through a galvano drive circuit 13. A tracking element 10 detects a displacement value of a mobile part of the galvanomirror 5 and a positioner 8 is driven through a positioner drive circuit 17 so that the value detected coincides with a specified target value. At a fine seeking or a multiple jumping, a track error binary coding circuit 14 detects a groove traversing speed of a head from a pulse interval in the track error to apply a multi-stage speed acceleration/ deceleration pulse to the galvanomirror 5 through an acceleration/deceleration pulse generating circuit 15 based on the speed detected. Thus, the groove traversing speed of the head is made to follow the target value.

Title: Magnetoresistance element and magnetic information reproducing method
Inventor: INOMATA KOICHIRO
IPC: G01R33/09
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To nondestructively read out magnetic information by a recording element using a magnetoresistance effect and to increase a reproduced output by providing a tunnel insulating film interposed between a ferromagnetic conductive film and a magnetic laminated film. SOLUTION: A magnetic laminated film in which first and second ferromagnetic conductive layers are antihero magnetically exchange-bonded with each other is used as a magnetic laminated film 6. The saturated magnetic field of this laminated film 6 is define as Hs. The recording to a ferromagnetic conductive film 4 is performed by the impressing if a recording magnetic field Hw. A the time of a reading, the tunnel current between the laminated film 6 and the conductive film 4 is used. That is, a read magnetic field Hr is impressed on the laminated film 6 to allign magnetizations in one direction. Since a nondestructive readout is needed, when the coercive force of the laminated film 6 is defined as Hc, the Hr becomes to be Hc<Hr.  Here directions of magnetizations of the laminated film +6 and the conductive film 4 are the same directions when the recorded state of the conductive film 4 is '1' and reversal directions when the state is '0'. Consequently, when a bias voltage is impressed between the laminated film 6 and the conductive film 4, a tunnel current is made to flow and then a small voltage is generated when the state is '1' and a large voltage is generated when the state is '0' in between both films.

Title: Switching element and memory element using current and electric field induction phase transition in manganese oxide material
Inventor: ASAMITSU ATSUSHI
IPC: H01F1/00
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for operating magnetic field and accordingly, to facilitate the incorporation of a switching element into conventional type electronic circuits, by using the insulator-metal transition induced by the current and electric field of a manganese oxide material basically composed of MnO3 and the antiferromagnetic- ferromagnetic transition accompanying it in forming the switching element. SOLUTION: Voltage is impressed at a specified temp. in a zero magnetic field on the manganese oxide crystalline body, which is basically composed of the MnO3 formed as an antiferromagnetic insulator by charge alignment and is expressed by the general formula R1-x Ax MnO3 indicating rare earth ions as R and alkaline earth ions as A. At this time, the high resistance value of 10<10> Ω is decreased by voltage impression and is switched to the low resistance state of about 10<5> Ω by the certain threshold voltage. When the impressed voltage is thereafter decreased, the resistance value restores the initial resistance by exhibiting a hysteresis.  Since the charge alignment antiferromagnetic insulator state is easily fused and is transferred to the ferromagnetic metallic phase by the magnetic field, the ease of melting of the charge alignment phase may be controlled if the external magnetic field is used.

Title: Radar equipment for vehicle
Inventor: YAMAMURA TOSHIHIRO
IPC: G01S17/06
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To ensure generation of alarm at a proper timming by calculating a relative speed only at the time when the distance of target substance is in a range of specified distance or below. SOLUTION: Distance calculating means 7 detects a distance R to a target substance. The value of the distance R is determined and the determination of whether relative speed calculation means 10 is operated or not is made. Namely, a specified value R-limit set to the maximum detection distance R-max or below and the actual distance R are compared with each other, and only in the case of R<R-limit the calculation means 10 is operated. Since the relative speed is calculated in the case that the distance with the target substance is only in the range of not more than the specified distance set not more than the maximum detection distance of radar, the calculated relative speed becomes the same as the true value, whereby after the application of LPF almost the same value is obtained.  Accordingly there occurs no delay in generation of alarm, thereby ensuring the generation at a proper timming.

Title: Power converter
Inventor: MOSE TADAO
IPC: H02M7/515
Filed: 1984-03-30
Abstract: PURPOSE:To obtain a high performance power converter by compensating the variation in a transmission gain by a signal compared of the state variation in a control system with the state variation in a simulation control system. CONSTITUTION:A power converter 1 has a thyristor converter 3 and a smoothing circuit 4, and supplies power to a load 2. The converter 3 is controlled at alpha by a phase controller 7 of a main current control system 13 to form a phase control signal 11 from a current deviation signal between a current feedback signal from a current detector 8 and a current command value 9. In this case, a simulation current control system 18 is composed of a simulation smoothing circuit 14 similar to the smoothing circuit 4 and a unit 17 simulating the controller 7. Thus, the second phase control signal 12 obtained through a compensating amplifier 21 from the system 18 is added to the signal 11 to obtain an input signal of the controller 7. In this manner, the transmission gain decrease of the system 13 is compensated to eliminate the large variation in the current control response.

Title: Surface light emitting type semiconductor laser
Inventor: YAMAMOTO EIJI
IPC: H01S5/00
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to continuously vary the radiating angle and shape of a laser beam, by providing means for applying a voltage to an embedded layer and a column. SOLUTION: Voltage applying means 14 for applying voltage is provided between an embedded layer 7 and a column 6. Since the layer 7 and the column 6 have different conductivity types, they form a P-N junction, and a depletion layer 17 is formed at both sides of the boundary between the layer 7 and the column 6. The thickness of the layer 17 is controlled by the voltage applied to the junction, and the larger the amplitude of the reverse bias to the junction is, the larger the thickness increases. Since the layer 17 has a function of blocking the carriers of electron or hole, it limits the route of the current to be implanted to an active layer 4. As a result, the region of the layer 4 for generating an optical gain is limited. Thus, the radiating angle of the radiating beam can be continuously varied or controlled, at the controllability of the oscillation lateral mode.
