Title: Video disk reproduction device
Inventor: OOTA KIMIHIRO
IPC: H04N9/89
Filed: 1990-06-28
Abstract: PURPOSE:To attain video disk reproduction with high picture quality by adding a low frequency component of a reproduced video signal to a control voltage of a time base collector for chrominance signal so as to improve a differentiating phase of the reproduced video signal. CONSTITUTION:An error voltage for a burst period sampled for each horizontal scanning period at a sample-and-hold circuit 18 is fed to one input terminal of an adder 26 the output video signal of a CCD obtained at a terminal 23 is fed to the other input terminal of the adder 26 via an LPF 25. The LPF 35 passes through a low frequency component (i.e., a luminance component) of the reproduced video signal and the adder 26 adds the component to an error voltage. The error voltage is fed to a phase shifter 15 and the reproduced video signal whose phase of chrominance component is adjusted based on a control voltage is fed to a post-stage circuit from an output terminal 27.

Title: Production of dense oxide superconductor
Inventor: TAKEDA YUKIO
IPC: H01L39/12
Filed: 1987-07-10
Abstract: PURPOSE:To obtain a dense oxide superconductor having high strength and current density, by sintering an oxide superconductor raw material powder with a hot-press and heat-treating the sintered product in air or in an oxygen atmosphere. CONSTITUTION:An oxide superconductor raw material powder such as a Y- Ba-Cu-O composition is sintered with a hot-press. The hot-pressing is preferably carried out at 750-950 deg.C and >=20MPa pressure. The sintered product is heat- treated in air or in an oxygen atmosphere preferably at 700-1,000 deg.C to obtain the objective dense oxide superconductor. The product has improved density by the sintering process using a hot press. Although a densified sintered material is liable to be converted into a tetragonal crystal form, phase-transition of the material to a rhombic crystal system can be carried out by the heat- treatment in hot air or oxygen to obtain a superconductor having excellent characteristics.

Abstract: PURPOSE:To obtain a valve timing control with high accuracy and smoothness by relatively rotating a cam shaft and a rotational body by the use of a torque change of the cam shaft, and regulating a normal-reverse relative rotational position by means of a pair of regulating means and a pair of gears. CONSTITUTION:When an engine is under a high load area, for example, a solenoid valve 32 is set ON, and operation oil press-fed from an oil pump 30 is introduced through an introducing passage 28 and an axial passage 29 to a pressure chamber 12, so that a pressure in the pressure chamber 12 is instantly increased.

Title: Power steering gear
Inventor: UCHINO KAZUYOSHI
IPC: B62D5/06
Filed: 1979-12-28
Abstract: PURPOSE: To prevent steered wheels from being deflected in one direction when back pressure becomes high, by shutting off a liquid supply passage and a passage, which is connected to a liquid chamber of larger liquid pressure reception area in a power cylinder, at one valve groove in the neutral position of the change-over control valve of a power steering gear provided with the power cylinder.  
     CONSTITUTION: When a vehicle is moving straight or the spool 28 of a change-over control valve 31 is in neutral position, a groove 26 is disconnected from another groove 24 but connected to still another groove 23 and still another groove 27 is connected to grooves 24, 25. For that reason, pressurized liquid is returned to a liquid reservoir 66 through the grooves 27, 25, a passage 4b and an orifice 60. The pressure at the upstream side of the orifice 60 or in the groove 27 is higher than that at the downstream side or in a passage 4 and enters into a liquid chamber 20  through a passage 13 to act to the smaller liquid pressure reception side of a piston  19. When a steering wheel is turned to the right, a shaft 11 is moved rightwards by  at a stroke δ and the spool 28 is moved rightwards so that a liquid pressure circuit  which produces motive power to deflect steered wheels rightwards is formed for a  power cylinder 17.

Title: Ribbon cartridge
Inventor: ITO KAZUNORI
IPC: B41J31/16
Filed: 1989-07-03
Abstract: PURPOSE:To obtain high printing quality by meshing the transfer pulley and transfer auxiliary pulley of an ink supply type ribbon cartridge only in an ink supply region and providing a layer composed of a water-repellent material to the surfaces of the pulleys or constituting two pulleys of a material containing the water-repellent material. CONSTITUTION:A transfer pulley 2 and a transfer auxiliary pulley 3 are meshed only by the middle stage pulley related to the supply of ink and both pulleys 2, 3 are constituted using 'SUMIFLUNON FP-91(R)' or 'YF-20(R)' a product of POLYPLASTIC. Since the meshing depth of tooth parts is always constant and sufficient meshing quantity can be secured, the remaining of the ink on the transfer pulley 2 is eliminated and the generation of density difference during continuous printing is prevented. Since the used water-repellent material is fluoroplastic, the sliding load of the transfer pulley 2 and the transfer auxiliary pulley 3 is reduced and the load to a printer main body is reduced.
