Title: Information recording medium of capacity variation type and its manufacture
Inventor: KAWARASAKI YOUICHI
IPC: G06K19/06
Filed: 1979-02-19
Abstract: PURPOSE: To obtain a recording medium from which signals are reproduced with efficiency, by forming on a surface a conductive corpuscle dispersed polymer material layer in a geometric shape corresponding to an information signal, and then by forming a metal layer under the layer.  
     CONSTITUTION: On discoid substrate 2, metal layer is formed by vapor-deposition, sputtering or the like and a polymer material of a mixture of conductive corpuscles dispersed at an adequate rate is applied on metal layer 3 in a spinner or spray method, etc., to a thickness of approximately several microns to form conductive corpuscle dispersed polymer material layer 4. Next, stamper 5 with an information signal formed is pressed against polymer material layer 4 to form on the surface of polymer material layer 4 recording surface 4a in a geometric shape corresponding to the information signal by pressing. Consequently, capacity variation type information recording medium 6 can be obtained. Since metal layer 3 resides near recording surface 4a, the impedance of a high-frequency transmission line lowers and signals conversion output efficiency improves, so that a reproduced signal can be obtained at a high S/N ratio.

Abstract: PURPOSE:To eliminate harmful effects of residual magnetism and to accurately mount into a drying chamber in the above captioned device for grain drying facilities by adsorbing with an electromagnet a drying box containing sample for self-imposed test, transferring it to a targeted drying chamber of a sample drier, and retreating, after insertion, by demagnetizing the electromagnet. CONSTITUTION:A traveling dolly 21 stands by at a position of receiving sample for self-imposed test, adsorbing an empty drying box 3 with an electromagnet 28. The sample finished with sampling is tossed into the empty drying box 3, run toward a targeted drying chamber 2 and inserted into the drying chamber 2 with a motor for rack movement 23. The power to the electromagnet 28 is then cut off. Next, the motor for rack movement 23 is reversed to retreat a rack 22. With that movement, the electromagnet 28 is also retreated, and the drying box 3 is then pressed into the drying chamber 2, for its secure mounting, with a drying box release spring not shown in the figure. This constitution makes it possible to accurately mount without receiving any effect of residual magnet.

When U-phase thyristor T u2  of a converter 12 causes a short-circuit, F u2  is fused, which is detected with a device 50a to open a switch 46. Consequently, the action of the pulse distributor of the converter is checked whereby the converter comes to a stop. Therefore, no current flows through the converter 12, which allows separation of the converter from the circuit by opening a breaker 16 on the AC side and breakers 20 and 24 on the DC side.

Title: Large power fet drive circuit
Inventor: UEDA MOTOO
IPC: H03K17/687
Filed: 1984-02-02
Abstract: PURPOSE:To accelerate the switching speed of a large power FET by driving the FET by an impedance converter of a low output impedance. CONSTITUTION:FETs 5a-5d are driven by a low impedance by inserting impedance converters 16a-16d between the secondary windings of insulated transformers 8a, 8b and the gates of the FETs 5a-5d. Since the impedance of a drive source is sufficiently small even if relatively large input capacity is presented at the FETs 5a-5d, the charging and discharging time constants for the input capacity can be reduced. As a result, the time for turning the FETs 5a, 5b, 5c, 5d ON and OFF, i.e., the time for turning ON and OFF can be shortened.
