Title: Vibro-isolating device for internal pump
Inventor: YANAI RIYOUICHI
IPC: F04D7/08
Filed: 1984-06-25
Abstract: PURPOSE:To improve a vibro-isolating effect ever so better, by installing a leg as directed to a pump casing from the lower part of a reactor pressure vessel, while setting up a groove in which this leg is fitted. CONSTITUTION:A leg 29 is projectingly installed in the opposite direction to a nozzle 28 formed in a reactor pressure vessel bottom part 21 of an internal pump, namely, toward a casing 24 vertically, and its tip end is made so as to be fitted in a groove 30 installed in an upper part of the casing 24. Therefore, during operation of a reactor, the casing comes to be locked at two spots in consequence whereby its frequency comes high, so a vibro-isolating effect is improvable and, what is more, earthquakeproofness in time of a seismic tremor is also improvable.

Title: Microwave part
Inventor: MATSUURA TAKASHI
IPC: H01P7/08
Filed: 1992-04-22
Abstract: PURPOSE:To reduce the temperature variation in resonance frequency, by directing a c-plane of an oxide superconductor crystal of which a superconducting path and a superconducting ground conductor are respectively formed in approximately parallel with the change direction of an electromagnetic field of a microwave introduced into a microwave part. CONSTITUTION:A first substrate 20 on which a superconducting path 10 formed of an oxide superconductor thin film whose c-axis of a predetermined pattern has an orientation parallel to the substrate is mounted and a second substrate 40 on which a superconducting ground conductor 30 whose c-axis has the orientation parallel to the substrate is whole mounted are held in a package 50a with both substrates stacked, and are sealed with covers 50b and 50c. A microwave introduced into the superconducting path 10 generates a magnetic field H and an electric field E. Accordingly, the magnetic field penetrates the superconducting path 10 and the superconducting ground conductor 30 from the direction parallel to a c-plane of an oxide superconductor crystal, that is, the direction perpendicular to the c-axis, and the variation is extremely reduced due to the penetration depth and the temperature of resonance frequency.

Title: Thermal transfer recording material
Inventor: SEKINE MIKIYA
IPC: B41M5/392
Filed: 1984-06-22
Abstract: PURPOSE:To contrive higher image preservability, by a method wherein an image-receiving layer comprising a UV abosrber and/or an anti-oxidant is provided on an image-receiving surface to be brought into contact with a transfer sheet. CONSTITUTION:The image-receiving layer comprising a UV absorber and/or an anti-oxidant is provided on the image-receiving surface brought into contact with the transfer sheet. Accordingly, transferred image with enhanced light resistance can be obtained. The melting points of the UV absorber and the anti-oxidant incorporated in the image-receiving layer are preferably 50-150 deg.C. When the melting points are lower than 50 deg.C, the image-receiving sheet becomes tacky, or blocking occurs. On the other hand, the UV absorber and the anti-oxidants having melting points of higher than 150 deg.C are not easily melted when being heated by a thermal head, so that they are not completely mixed with the transferred ink layer, and the effect thereof is markedly lowered.

Filed: 1985-06-14
Abstract: PURPOSE:To execute a highly speedy operation without bringing about the complication by providing a common electric power source wire to be able to obtain the binary logic condition by the voltage and using the logic condition of the common electric power source wire as a row selecting signal. CONSTITUTION:When compared with the on resistance of transistors Q1 and Q2, load resistances R1 and R2 have the sufficiently larger resistance value, the information stored to a memory cell is hardly destructed until the electric power source voltage of the memory cell is reduced close to the threshold of the transistors Q1 and Q2. Consequently, even when the voltage of a common word line 27 is reduced up to 2V, the action of the memory cell is not damaged. On the other hand, since for NAND circuits 24 and 25, the threshold of the input level is 3V, when the common word line 27 is 2V, the circuits are operated with the input as '0'. Consequently, a NAND circuit 24, etc. which are given from a block selecting signal line 21, etc. and whose block selecting signal is '0', output '1' from the output terminal, and give to terminals 3 and 4 of the memory cell of respective blocks and select these cells. Thus, the high speed and the low power consumption can be executed with a high yield.

Abstract: PURPOSE:To reduce the value of a capacitor equivalently and thus contrive to change the circuit into a low noise one by a method wherein negative feedback is given from the source voltage to the gate voltage. CONSTITUTION:A transistor 12 wherein the capacitor 18 is connected on the source (on emitter) side of the transistor is made to act in saturation, and thus the charge of the above-mentioned capacitor is transferred to the drain (or collector) side of the MOS transistor 12. An amplifier 21 which amplifies and inverts the voltage on the source (or emitter) side of the MOS transistor 12 is provided, and then the output of the amplifier 21 is impressed on the gate (or base) of the MOS transistor 12 during at least a partial period of a charge transfer period. This invention can be attained even by the use of a junction type field effect transistor or a bi-polar transistor. In either case, the capacitor appears small in size owing to the negative feedback by the amplifier 21, and the random noises due to these capacitors can be suppressed.

IPC: B21B37/00
Filed: 1985-06-14
Abstract: PURPOSE:To improve the productivity of rolling by subtracting a rolling time and rolling interval of preceding billets from the treatment time of coilers and controlling the rolling interval in accordance with the subtracted value. CONSTITUTION:Plural product coilers are disposed to one rolling line. The time T0(sec) necessary for the treatment with the coilers is preliminarily determined. The rolling time T1-Tn for each of blank materials are then determined from the measured weight prior to loading into a heating furnace, product size, rolling speed, etc. The rolling time Tn-1 and rolling interval tn-1 of the preceding billets are subtracted from the treatment time T0 of the coiler and the rolling interval is controlled with the min. rolling interval t0 if the subtracted value is equal to or below t0. The rolling is executed with the rolling interval tn as the subtracted value when the subtracted value exceeds t0. The waste of the rolling interval is thereby eliminated and therefore the productivity of the rolling is improved.
