Title: Magnetoresistive effect head
Inventor: NOGUCHI SHIN
IPC: H01F10/08
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To decrease an antimagnetic field to fix the magnetization direction of a fixed layer and to obtain a high reproducing output with high recording density even with low magnetoresistance, by aligning the magnetization direction of a ferrimagnetic layer and the magnetization direction of the fixed layer opposite to each other to produce exchange coupling. SOLUTION: A ferrimagnetic layer 20 comprising a TbCo alloy or the like and a fixing layer 17 comprising TM atoms such as Co are laminated to produce exchange coupling of the magnetization 21 of the fixing layer 17 and the magnetic moment 24 of the TM atoms in the ferrimagnetic layer 20 so that the magnetization direction of the fixed layer 17 is opposite to the magnetization direction of the ferrimagnetic layer 20. The magnetostatic field 26 leaking from the edges of the fixing layer 17 is absorbed by the ferrimagnetic layer 20 to produce an antimagnetic field and eliminates gradient in the magnetization of the fixed layer 17 to make the magnetization direction uniform. Thereby, even when the magnetoresistance MR is low, decrease in the magnetoresistive change ΔR in the spin valve layer can be decreased.  By controlling the compsn. and film thickness of the ferrimagnetic layer 20 to obtain an almost same magnetization-film thickness product as that of the fixed layer 17, the exchange coupling can be enough produced to increase its effect.

IPC: H04M3/22
Filed: 1985-03-15
Abstract: PURPOSE:To reduce the cost by forming two devices by all the same constitution, and constituting a system switching circuit of a duplexing device by two sets of devices of one kind. CONSTITUTION:Devices 1, 2 are formed by the same constitution, and form a system switching circuit of a duplexing device. When a power source is turned on in a state that output circuits 11, 21 are normal, a relay ALM1 does not operate since a terminal 106 is not grounded, and accordingly, a relay ACT1 operates, and by a make contact act 1, an output of the output circuit 11 is sent out of a terminal 101. In such a state, if an abnormality is generated in the output circuit 11, the terminal 106 of a detecting circuit 12 is grounded, therefore, the relay ALM1 operates and an operation of the relay ACT1 is released, and make contacts act11 and act12 are opened. As a result, a relay ACT2 of the other device 2 operates and a make contact act21 is closed, and an output of the output circuit 21 is sent out of a terminal 201.

Title: Information processor, reservation processing method and data distributing method therefor
Inventor: YAMANE TETSUYA
IPC: H04N21/472
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain a device which is easy to operate and is hard for a incorrect input to be made and an mis-operations to occur by executing operation processing (e.g. registration, reference and updation or elimination) about reserva tion information to reserve prescribed processing (e.g. recording, outputting, transmission, receiving or other handlings) to broadcasting data, based on a prescribed operation to previous notice data. SOLUTION: All inputs from an operating device 4104 are received by a data recording part 4121 and in contrast, the part 4121 does not perform processing about a reservation event directly but communicates it to a reservation list managing part 4122. When the part 4121 receives an instruction about the previous notice event from the device 4104, it transfers the received data to the part 4122. Because an output comes from the part 4122 when it is an instruction about the display of a reservation list, the part 4121 outputs it to a previous notice display device 4105. The part 4122 takes charge of producing and recording the reservation list, etc.

Abstract: PURPOSE:To improve an S/N of a sound signal by providing a simple current switching circuit, and making a ratio of a recording current of the sound signal and a video signal larger than a usual state, in case of recording only the sound signal. CONSTITUTION:In a VTR, an FM-modulated recording sound signal 4 is recorded in a magnetic tape by a rotary magnetic head 7 through an amplifier 5 and a current switching circuit 6. Subsequently, an FM-modulated recording video signal 1 is lap-written and recorded on a magnetic tape by a rotary magnetic head 3 through an amplifying circuit 2. In case that when only the sound signal has been recorded, a recording signal current outputted from the switching circuit 6 becomes large, and the head 7 magnetizes strongly the tape. Therefore, thereafter, the sound signal which is not erased but left, when a video signal current of no-signal of a recording current has been lap-written becomes large, and an S/N of the sound signal is improved.

Title: Brushless linear motor

IPC: H02K41/02
Filed: 1984-03-21
Abstract: PURPOSE:To reduce the variation in the speed by gradually increasing an air gap between a movable element and a stator at the positions in the same direction as the moving direction of the element, thereby decreasing the reverse attracting force. CONSTITUTION:A movable element 1 of a brushless linear motor is composed of magnetic materials having a pitch P1, and a coil 4 is wound on one tooth 3 of a stator 2. A magnet is formed on the side of the core of the stator 2, a magnetic flux from the magnet is emitted through a stator core 3, teeth 3 and a main gap to the element 1, and returned to the magnet. Thus, the element 1 is attracted and repelled by poles P1-P9 formed in the stator 2, the permanent magnet and a coil 4 to move in the direction of an arrow as shown. In this case, the poles P4-P6, P7-P9 increases the air gap distance l2 to the teeth of the element 1 in the direction that the element 1 moves. Thus, reverse torque can be reduced.

Title: Function element
Inventor: YAMASHITA TERUO
IPC: G02F1/01
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a function which can be utilized for an optical element, display element, recording element, etc., by arranging the polarization directions of a charge transfer complex in a specified direction. CONSTITUTION:The polarization directions of the charge transfer complex are arranged in the specified direction. More specifically, the polarization by the charge transfer arises at the boundary face between an acceptor layer 2 and a donor layer 3 and the dipole moments by the polarization are arranged to face the specified direction at the boundary face. The charge induced by such polarization in this state is generated on the surface of the laminated layer and the electric charge weight thereof is increased by light. The element is thus used as an optical sensor or is used also as a light guide as the element allows easy propagation of light by an increase in the refractive index in the charge transfer region. The change in the capacity of a capacitor utilizing the induced charge is also utilizable as pressure sensor or other sensors.

Inventor: KAMEI TAKAO
IPC: C10B45/02
Filed: 1984-03-19
Abstract: PURPOSE:To allow precompressed briquette block unit to be smoothly introduced into a final briquetting machine without causing partial peeling or breakage of the briquette block unit, by applying the pressure of compressed air to the lower surface of the block unit in the introduction thereof into the final briquetting machine. CONSTITUTION:Raw coal 2 is slightly compressed from both sides thereof in a pre- briquetting machine 11 to form a briquette block unit 5C. After a space 36 is filled with compressed air fed from an air feeding hole 30, introducing gates 27, 37 are opened and the block units 5C are allowed to slowly drop onto the bottom of the space 36. Though the compressed air is escaping during the dropping of the block units, compressed air is continuously made up and hence, supporting force by air is not lost and there is no possibility that the blocks 5C are partially peeled off or broken. When the introduction of the blocks into the final briquetting machine is completed, the gate 37 is closed. When a press head 29 is moved forward by a hydraulic cylinder 3, the blocks are compressed into briquette blocks 5a which are then combined with preceding briquette blocks 5b, thus producing compressed briquettes 5.
