Title: Photomagnetic memory medium
Inventor: YONENOU KAZUNARI
IPC: G11B11/10
Filed: 1982-03-31
Abstract: PURPOSE:To enable high-density vertical magnetic recording, by forming a thin film having Kerr effect and smaller coercive force than magnetic flux density for magnetizing a vertically magnetizable film on the magnetizable film and by uniting the films in a body. CONSTITUTION:A thin Mn-Bi film 3 having Kerr effect is formed by vapor deposition on a vertically magnetizable Co-Cr film 2 formed by sputtering. Signals such as upward signals 1 and downward signals 0 are recorded in the film 2 in accordance with the direction of magnetization as shown by arrows in the figure. When the coercive force of the film 3 is smaller than the magnetic flux density of the film 2, the film 3 is also magnetized by magnetic fields leaked from the film 2 as shown by arrows in the figure. Gd-Tb-Fe is suitable for use as the material of the film 3 besides Mn-Bi. High-density recording and reproduction can be carried out by making use of Kerr effect.

Title: Optical transmitter
Inventor: ASAKAWA WATARU
IPC: H04B10/07
Filed: 1991-02-25
Abstract: PURPOSE:To eliminate the need for gain adjustment of a received optical signal by sending an optical signal at a prescribed level, obtaining a transmission line attenuation from a reception level on the other hand and adjusting an output to be a prescribed level at a destination. CONSTITUTION:An optical transmission reception circuit 1 applies a drive control signal corresponding to a signal inputted to a drive circuit 11 to a light source 12. The optical signal generated from the light source 12 is sent to an optical transmission reception circuit 3 via an optical fiber 21, received by a light receiving element 33 and outputted via an automatic gain control amplifier 34. A level detection circuit 35 detects this output level and adjusts the gain of the amplifier 34 so that the level is constant and detects the attenuation of the fiber 21 and gives the result to an AGC control circuit. The circuit 36 controls the level of a drive control signal fed to a light source 32 by using the attenuation so that the level received by the light receiving element 13 of the circuit 1 is substantially constant via an optical fiber 22. The output of the element 13 is amplified by the amplifier 16 and the gain adjustment at the receiver side is not required.

IPC: G11B7/09
Filed: 1987-03-09
Abstract: PURPOSE:To realize automatic winding, to make a device light weight, and to obtain high efficiency, by winding two coils (a focus coil and a tracking coil) in directions orthogonal to each other directly across a bobbin. CONSTITUTION:Across the bobbin 11 holding an objective lens 12 almost in its center upper part, a focusing and a tracking coils 13a-13c are wound directly. Magnetic flux outputted from magnets 15a and 15b cross the coils 13a-13c, and a magnetic circuit closed to an inner yoke 14a is formed. In such a way, it is possible to reduce coil resistance, and to make the coil light weight, and to increase generative speed per unit watt, and to obtain the high driving efficiency of the objective lens. Also, since the automatic winding of the coils 13b and 13c for tracking drive can be performed directly across the bobbin 11, the number of processes can be reduced remarkably than ever.

Title: Yawing controller for vehicle
Inventor: SHIRAISHI SHIYUUJI
IPC: F02D45/00
Filed: 1987-03-09
Abstract: PURPOSE:To control the yawing of a vehicle, by finding each reference yaw rate with only a steering angle of a steering wheel or this steering wheel and a detected yaw rate, and installing a correcting means for the yawing due to slippage with this detected yaw rate. CONSTITUTION:A yaw rate of a vehicle is detected when each signal out of speed sensors Sl and Sr for free rolling wheels Wrl and Wrr is inputted into a yaw rate detecting means 1. This detected output is inputted into a reference yaw rate generating means 2 while it is inputted into a substracter means 3. On the other hand, output of a steering angle detecting sensor Ss is also inputted into the reference yaw rate generating device 2 and thereby a reference yaw rate is found. Next, a difference between this reference yaw rate and the preceding detected yaw rate is found by the subtracter means 3. And, the difference is compared with the reference value by a comparator 5, and the result is outputted to an engine power controller 6, thereby controlling engine power. Therefore, the detected yaw rate is controlled to the vicinity of the reference yaw rate, thus it is made so as to coincide with the yaw rate suitable to a driver's desire.

Title: Gallium arsenic semiconductor integrated circuit
Inventor: MATSUE SHUICHI
IPC: H03K19/0952
Filed: 1988-03-09
Abstract: PURPOSE:To prevent the increase of a through current due to the rise of temperature by connecting one or more Schottky diodes, which have the gate of a first metallic semiconductor field effect type transistor TR as anodes, in series between said gate and the earth level or a second power source. CONSTITUTION:The signal inputted from a node 11 is inverted in the same level and is transmitted to a node 14. When the temperature rises, the Schottky current is increased and the clamp level is reduced, and therefore, potential of nodes 14 and 13 are reduced. That of a node 12 is reduced also because of the existence of Schottky diodes 21 and 22. Potentials of nodes 13 and 12 are reduced by an extent corresponding to two Schottky diodes and are reduced approximately equally. The drain current of a normally turned-on MOSFET 3 is in the saturated state. Consequently, the through current is not increased because the drain current of the MOSFET 3 is not changed though potentials of nodes 12 and 13 are equally reduced by the rise of temperature.

IPC: H04N1/00
Filed: 1983-03-31
Abstract: PURPOSE:To prevent effectively deterioration of a picture quality due to notches of a picture by constituting so that a paper feed motor is not driven while an alternately read type heat sensible recording head is recording a received picture, and the paper feed motor is driven after recording of the received picture is ended. CONSTITUTION:(a), (b) and (c) denote a figure for showing an electric conduction timing of an alternate read type heat sensible recording head 4, a figure for showing a driving timing of a paper feed motor 7, and a figure for showing a displacement of a movement of recording paper respectively. A head electric conduction pulse of one line portion is massed so as to be front-justified as much as possible, an idle time T for driving the paper feed motor 7 is made, and the paper feed motor 7 is driven in a state that recording is not executed. The first paper feed is executed a little before electric conduction and recording to an electrode CH2 are ended, and the second paper feed is executed after some delay. The paper feed motor 7 generates an actual displacement after a constant delay, after a motor driving request is received. Accordingly, by taking such a facsimile recording controlling system as above, it is possible to form a state that recording paper does not move at all when a picture being recorded.

Abstract: PURPOSE: To perform energy-saving in an air conditioning method by providing two duct systems, and mixing the primary air from an air diffuser in a perimeter zone from an interior air conditioner and the diffused air from a terminal unit.  
     CONSTITUTION: Circulated air sucked from an air circulation tube 2 by a blower 1a is mixed with fresh air from an external air guide tube 3, the mixture is passed through a filter 1d, is partly passed through a chilled water coil 1c, thus reaches a suitable temperature, is passed through a humidifier 1b, and is then diffused from a diffuser 5 of an interior zone into a room. The remaining air passed through the filter 1d is, on the other hand, passed through a chilled water coil 1c' and a humidifier 1b', and is diffused from a diffuser 5a in the perimeter zone through a duct 4a. Since the air in the terminal unit 6 is thus mixed with the primary air at an approximately room temperature, it is efficiently mixed to reduce the mixture loss.
