Title: Optical recording medium and production thereof
Inventor: KAWAKAMI HARUO
IPC: G11B7/24062
Filed: 1991-08-23
Abstract: PURPOSE:To assure CN and erasing ratio sufficiently high over a wide range of rotating speeds by forming cooling capacity varying means which decreases a cooling capacity with an increase in radius in the rotating radius direction of the optical recording medium. CONSTITUTION:A reflection cooling layer 5 is so formed that the film thickness decreases according to the radius of the rotating motion. The reflection cooling layer 5 may also be so formed that the amt. of a thermal conductivity lowering compsn. increases according to the radius. If, for example, the reflection cooling layer is formed of Al as its essential compsn., Ti may be used as the thermal conductivity lowering compsn. The circumferential speed is higher and the heat diffusion rate is higher nearer the outer peripheral part of the optical recording medium which makes rotational motion. Then, the cooling rate in the radial direction can be kept nearly constant and the CN and erasing ratio of the optical recording medium can be held to attain sufficiently high values by using the cooling capacity varying means having the small capacity to cool the optical recording material layer 3 in the outer peripheral part and the large capacity in the inner peripheral part.

IPC: C07C21/06
Filed: 1981-12-25
Abstract: PURPOSE:To prepare vinyl chloride with suppressing the formation of chloroprene and aceylene as by-products without damaging a thermal decomposition reaction, by decomposing thermally 1,2-dichloroethane in the presence of hydrogen. CONSTITUTION:In decomposing thermally 1, 2-dichloroethane, the thermal decomposition is carried out in the presence of 0.05-3.0 moles, preferably 0.2-1.0 hydrogen.

Filed: 1994-09-06
Abstract: PURPOSE: To perform guidance for a missile, by a method wherein a twodimensional detector is fastened the body of the missile, and while the missile is stabilized in a space by electronic data processing instead of a mechanical gimbal mechanism, guidance signals are generated. CONSTITUTION: An attitude angle velocity signal 23 of a missile is detected by an inertial sensor 6 and a tracking point angle signal 21 is detected by an image data processor 8 on the basis of an outputted image from a two-dimensional detector 3. A tracking point angle signal 22 is differential-found by a differentiator 13. On the basis of both a tracking point angle of a target and a temperature of an optical lens, a gain at the time when scale factors of these signals are made equal to each other and a phase at the time when detected times thereof are made equal to each other, are respectively adjusted by a gain adjuster 11 and a phase adjuster 12, and these values are added by an adder 14.  In this way, independent of the attitude fluctuation of the missile, a change rate of a visual line angle to be formed between the missile and target is directly found and is outputted as a guidance signal.

Title: Inverter device
Inventor: KOBAYASHI SUMIO
IPC: H02P27/06
Filed: 1981-12-26
Abstract: PURPOSE:To shorten the idling time of a motor by increasing the magnetic flux of the motor when the motor is shifted from braking operation to idling operation and increasing the loss. CONSTITUTION:A voltage type inverter device is composed of a main circuitI and a control circuit II. When the output of a comparator 19 which compares the output of a voltage detector 17 with the set value of a voltage setter 18 is generated and a motor 4 shifts from braking operation to idling operation, the gain of a voltage controller 21 is increased, and the terminal voltage of the motor 4 is raised. The frequency at this time is constant since the output signal of an acceleration or deceleration limiter 12 is clamped. Accordingly, the magnetic flux of the motor 4 increases, the iron loss of the motor 4 increases, and the exciting current increases, thereby inccreasing the copper loss. The energy stored in the capacitor 2 is consumed early by these losses.

Filed: 1981-12-29
Abstract: PURPOSE:To realize a highly accurate and efficient method of formation of an inductive thin film magnetic head, by extending a conductor from a coil part to detect that a prescribed value is obtained for the depth of a gap which is under a cutting process. CONSTITUTION:A substrate 1 is made of a magnetic material having a comparatively low level of electric resistance, and an upper magnetic layer 2 touches the substrate 1 through a part 2' of the layer 2. A conductor 4 is extended up to a gap part 5 from a coil 3 to have a contact with the layer 2 at a hatched part 4'. The edge part 6 of the conductor 4 is set at a position where a gap forming process is over. Therefore the distance shown by Gd is equal to a desired depth of the gap. The layer 2 is made of a conductive magnetic material, and as a result a coil terminal has conduction with the substrate 1. A head element is formed and then cut from the direction of an arrow 7 into a desired depth of the gap. While this process is carried out, the conduction between the coil terminal and the substrate 1 is monitored. Then the processing is finished at a time point when the conduction is cut off between the coil terminal and the substrate 1.

Title: Code hopping type spread spectrum communication system
Inventor: NAGAZUMI YASUO
IPC: H04J13/16
Filed: 1987-08-27
Abstract: PURPOSE:To attain code hopping between transmitters and receivers by providing plural individual code synchronizing means corresponding to a shoed noise supposed to be used by a transmission side. CONSTITUTION:Shoed noise (PN) codes selected by a sequence from the transmission side are synthesized by a code multiplexer 104 and the synthesized code is subjected to code modulation with respect to an input signal and the result is sent. On the other hand, a reference signal is generated simultaneously by an S unit 18 corresponding to the PN codes of a prescribed number supposed to be used by the transmission side and the coincidence with the reception signal is monitored respectively. A reference signal coincident therewith enters respectively a tracking group at that point of time, and when the synchronization is acquired with respect to all reference signals used finally for code modulation, the shoed noise being the result of synthesis of the reference signals can be demodulated entirely. Thus, the operating effect peculiar to the code hopping technology is offered in addition to the operating effect peculiar to the multiplex spread spectrum communication system.
