Title: Magnetic recording and reproducing device with waveform equalization circuit
Inventor: IKEDA KAZUMASA
IPC: H04N5/91
Filed: 1989-12-05
Abstract: PURPOSE:To improve a reproduced image by providing a tap gain memory which varies the characteristic of a transversal filter at an odd-numbered field and an even-numbered field independently and performing a waveform equalization. CONSTITUTION:A recording and reproducing part is provided with a waveform equalization circuit, and performs the recording/reproduction of a video signal to which a ghost cancel reference GCR signal inputted to an input terminal 1 is inserted. Then, the waveform equalization of a reproducing video signal is performed based on the GCR signal and a tap coefficient obtained by the arithmetic processing of a reference signal with the transversal filter 2. Next, the convergence property of the error waveform of the filter 2 is discriminated with the sum of squares of the tap coefficient at a convergence property discrimination circuit 19. When convergence to a prescribed value is obtained, a mode migration signal is outputted, and a switch 15 is switched. Then, the tap gain memory 18 stores the tap coefficient selectively in a corresponding area corresponding to whether the mode migration signal exists in the odd-numbered field or the even-numbered field, and the characteristic of the filter 2 can be varied independently. In such a way, it is possible to surely perform the waveform equalization even on different kinds of transmission lines, and to obtain a satisfactory reproduced imaged.

Title: Manufacture of positive electrode active material
Inventor: KATO NAOYUKI
IPC: H01M4/525
Filed: 1994-11-29
Abstract: PURPOSE: To provide a positive electrode active material of a battery that resists refinement even after repeated charge and discharge under heavily loaded conditions and has a high energy density by using powders with a predetermined tap density in manufacturing the active material from an Li compound and powders of a metallic salt, a metal oxide or a metal hydroxide. CONSTITUTION: When an Li compound and powders of either a metallic salt or a metal oxide are mixed and baked to manufacture a positive electrode active material, powders of a metallic salt, a metal oxide, or a metal hydroxide with a tap density of 1.4g/cc or more are used. The metallic salt, metal oxide, or metal hydroxide powders with a tap density of 1.4g/cc or more are normally a spherical or semi-spherical aggregate of fine primary particles closely held together. Since such powders have large contact areas among them, when baked together with the Li compound the powders produce a highly solid and strong Li-metal complex oxide.  In a battery which uses this oxide as positive electrode active material, the positive electrode active material retains its solid form even after repeated charge and discharge under heavily loaded conditions and is thus kept from refinement, providing a good cycle characteristic.

Title: Inverter control type electric blower
Inventor: YAMAMOTO TATSUHIKO
IPC: H02K1/04
Filed: 1989-12-07
Abstract: PURPOSE:To improve the efficiency of heat dissipation by installing a rotor- position detector to a stator core, on which a coil is wound, monolithic-molding these parts with a thermal-conductive electrical insulating resin and forming the external shapes of each side surface of the molded form in the same form respectively. CONSTITUTION:When a rotor 4 is turned and a blower 7 is rotated, a cooling air flow flows into a motor casing 2, and passes through a cooling air path 3, etc., and is discharged to the outside from an exhaust port 5. The shapes of each side surface are equalized in the external shape of a resin-molded stator 8 at that time, and the sectional areas of air gaps among the stator 8 and each cooling air path 3 are set at the same value. Consequently, cooling air passing through each cooling air path 3 is made uniform, and a turbulent flow is difficult to generate. Accordingly, pressure loss by the turbulent flow is reduced while cooling efficiency is increased. A stator core 9 is monolithic-molded with a rotor position detector 12 by a resin, and heat-dissipating properties and water resistance are improved.

Title: Method for processing oxide superconducting film

IPC: C04B41/87
Filed: 1987-12-18
Abstract: PURPOSE:To enable a high quality fine pattern of an oxide superconducting film to be produced, by a method wherein the oxide superconducting film is processed by means of a lift-off technique utilizing a combination of a spacer film which is dissolved in an aqueous solution of ammonium fluoride (NH4 F) and the aqueous solution of ammonium fluoride. CONSTITUTION:After a spacer film 12 which is dissolved in an aqueous solution of ammonium fluoride is formed in the predetermined pattern on a substrate 11, an oxide superconducting thin film 15 is formed on allover the substrate body. Subsequently, the spacer film 12 is dissolved in the aqueous solution of ammonium fluoride, thereby the oxide superconducting thin film 15 is processed by means of a lift off technique. For example, a SiO2 film 12 is deposited on a SrTiO3 substrate 11, and subsequently a Si3N4 film 13 is deposited on the SiO2 film 12. Next, a photoresist 14 is formed in the predetermined pattern on the Si3N4 film 13. Further, after the Si3N4 film 13 is selectively etched through the photoresist 14, the SiO2 film 12 is etched using the aqueous solution of NH4F. Next, after an YBa2Cu3O7-delta film 15 is formed on allover the substrate body by means of a sputtering, the SiO2 film 12 is infiltrated with the aqueous solution of NH4F to dissolve it, Thus, the YBa2Cu3O7-delta film 15 thereover is selectively removed, thereby a stripe-shaped superconducting wiring is formed.

Title: Scroll type fluid machine
Inventor: HIRANO TAKAHISA
IPC: F04C18/02
Filed: 1990-11-22
Abstract: PURPOSE:To prevent laps from being excessively worn by fitting a counter weight which produces centrifugal force in the direction opposite to that of centrifugal force produced when a turning scroll is rotated, onto a drive bush, and thereby restraining the lap contact pressure of paired scrolls from being excessively high. CONSTITUTION:A turning scroll 2 has a cylindrical boss 4 projected at the center section of the outer surface of its end plate 2a, and a drive bush 5 is fitted in the boss 4 via a bearing 6. A slide hole 7 is bored in the drive bush 5 in which a drive pin 9 is fitted, which is projected out of the end face of a rotating shaft 8 while being eccentric in center. In this case, a counter weight 10 is concurrently fixed onto the drive bush 5, so that centrifugal force is thereby produced by means of the counter weight 10 in the direction opposite to that of centrifugal force acting on the bush when the turning scroll 2 revolves so as to be turned. This thereby allows contact pressure between the side surfaces of the spiral laps 2b and 1b of both of the turning scroll 2 and the stationary scroll 1, to be constant regardless of the number of revolution of the rotating shaft 8, thereby preventing the laps 1b and 2b from being excessively worn.
