Title: Liquid crystal display device and its production
Inventor: YAMAZOE HIROSHI
IPC: G02F1/1337
Filed: 1987-09-21
Abstract: PURPOSE:To enhance the hydrophobicity of an oriented film so that a large- capacity display is executed by forming a fluorine polymer by a plasma polymn. treatment using fluorine monomers on a resin layer formed on a substrate and subjecting the layer to a rubbing treatment, thereby forming the oriented film. CONSTITUTION:A polyimide layer, polyamide layer or polyamic acid layer is formed on the substrate. The fluorine polymer is formed thereon by the plasma polymn. treatment using the fluorine monomers and is subjected to the rubbing treatment. The polyimide layer, polyamide layer or polyamic acid layer formed on the substrate is otherwise subjected to the rubbing treatment and the fluorine polymer is formed thereon by the plasma polymn. treatment using the fluorine monomers. The oriented film of the liquid crystal display device is formed in such a manner, by which the hydrophobicity of the oriented film is enhanced and the large-capacity display is satisfactorily executed.

Title: Seat belt device for vehicle
Inventor: TOMIMATSU KAZUNORI
IPC: B60R22/24
Filed: 1993-09-22
Abstract: PURPOSE:To provide a seat belt device for vehicle which dos not produce any uncomfortable hammering sound when a lock piece is engaged with an engagement hole. CONSTITUTION:Since the area of an engagement hole 5 which touches the inclined rear surface 27 of a lock piece 13 is a supporting surface 30 with a curvature corresponding to the inclined rear surface 27, the top part 27a of the lock piece 13 is locked energetically into the engagement hole 5 by an elastic restoring force, and the tone of hammering sound occurring when the inclined rear surface 27 of the lock piece 13 touches the supporting surface 30 is low because the contact area between the inclined rear surface 27 and the supporting surface 30 is large. Thus conventional uncomfortable high tone hammering sound due to point contact is not produced, and sound environment in a cabin can be improved.

Title: Optical pickup device
Inventor: MAEDA HIDEO
IPC: G11B7/135
Filed: 1989-09-12
Abstract: PURPOSE:To enable signal detection only by one optical system, to reduce cost and size of an optical pickup device by arranging a dual grating, which is equipped with a polarized light separating diffraction grating and a beam splitting diffraction grating, on an optical path between a semiconductor laser and a recording medium. CONSTITUTION:Since a light beam emitted from a semiconductor laser 12 is passed through a collimator lens 13 and vertically made incident on a polarized light separating diffraction grating 14a of a dual grating 14, the incident light is made incident on a beam dividing diffraction grating 14b on an opposite side almost without being diffracted. A magneto-optical disk 16 is irradiated through an objective lens 15 with the light diffracted by the diffraction grating 14b. The reflected light from the disk 16 is passed through the objective lens 15, transmitted through the diffraction grating 14b and generates + or -1st order diffracted light. The diffracted light is made incident on the diffraction grating 14a and Bragg diffraction is executed to the light. Then, polarized separation into S and P polarized waves is executed and the light is made incident through the collimator lens 13 on 4-division photodetectors 17b and 17c and 2-division photodetectors 17a and 17d. Then, a focus error signal and a track error signal are respectively detected.

Title: Channel selection circuit
Inventor: HIRABAYASHI TSUNETO
IPC: H04N5/44
Filed: 1988-09-21
Abstract: PURPOSE:To reduce the channel selection time without losing the operating margin by shifting the center frequency of an AFT from the optimum tuning point only while a tuning voltage is being swept. CONSTITUTION:When an operation section 8 is operated to cause the state of up-search or down-search from, e.g., the state of receiving an optional station, a signal commanding this state is applied to a tuning voltage generating circuit 5 to start the sweep of the tuning voltage. The tuning voltage is fed to an electronic tuner 2 and to a voltage sweep discrimination circuit 6, then the discrimination circuit 6 discriminates it to be in the sweeping state and a tuning frequency switching circuit 7 shifts the center frequency of the AFT from the optimum tuning point. Thus, the similar operating margin is ensured for both the up-search and down-search and the tuning voltage sweep speed is quickened.

Title: Reel desk controller
Inventor: KAWAI TSUTOMU
IPC: G11B15/43
Filed: 1989-09-14
Abstract: PURPOSE:To make torque control satisfactory by locking one end of a torsion coil spring to a stopper, locking the other end to a tape detection arm part, operating the spring in a winding fastening direction when the tension of a tape is weak, and operating it in a winding unfastening direction when the tension is strong. CONSTITUTION:A torsion coil spring 2 is provided on the outer peripheral surface of a resin reel desk 1, one end 2a of the coil spring 2 is hung to a stopper 4 and another end arm 2b of the coil spring 2 is hung to a tape tension detection post 6. When the tension of the tape is smaller than a prescribed value, a tape tension detection arm 5 is operated in a direction, where the winding of the coil spring 2 is fastened, with a fixed part 5a as a fulcrum. Then, frictional force with the disk 1 is enlarged and the tape tension is enlarged. When the tape tension is large, the coil spring 2 is set in the winding unfastening direction and accordingly, the tape tension is made small. Thus, since the necessity of a band brake is eliminated for sticking felt, etc., the number of parts are reduced.

It reads the car speed from a car speed sensor 11, compares the speed with the set value which is close to zero, and turns off the check valve 15 when the set value is exceeded. The check valve 15 shall remain on when the output from comparison is below the set value. In this constitution, the check valve 15 is turned off during running, which does not generate any obstacle running, but the braking force is retained during application of brakes and the car is prevented from moving off.

Title: Optical head
Inventor: NAGANO TSUYOSHI
IPC: G11B7/135
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To enable a high density recording medium to be recorded and reproduced in the stable state of servo operation with a small loss of light quantity. SOLUTION: A light source 1 supplys a light beam having both polarizing components in the direction of x axis and in the direction of y axis to an analyzer 3. The analyzer 3 makes light beams of all polarizing components transmit through a circular aperture part 3a but a light beam of a polarizing component in the direction x transmit through a polarizing part 3b and interrupts a light beam of a polarizing component in the direction y. Since the light beam of the polarizing component in the direction x does not receive aperture restriction, the beam is converged with a large numerical aperture and since the light beam of the polarizing component in the direction y receives aperture restriction, the beam is converged with a small numerical aperture.  A polarizing beam splitter 7 reflects the light beam of the polarizing component in the direction x and transmits the light beam of the polarizing component in the direction y through. A data signal required for high resolving power is detected by a detector 9 and an error signal easily affected by external disturbance is detected by a detector 11.

Title: Video disk for high definition television
Inventor: KOIZUMI TOSHIO
IPC: H04N5/91
Filed: 1990-09-10
Abstract: PURPOSE:To reduce an adverse influence upon a video signal due to intermodulation by utilizing a Wobble signal for ternary 3-ary converted CIRC signal. CONSTITUTION:Information is newly multiplexed by slightly oscillating (Wobbling) to right and left with oscillating width 10 the tangential direction of bit trains 7a-7c to an advancing direction. EFM modulation is exerted upon the CIRC code used for a compact disk. For this EFM modulation, the run length is limited to 3-11 bits and a binary code average directing a Digital Sum Value toward zero. In this case, since a binary code having only a binary state is not desirable, the CIRC code is converted to the ternary 3-ary code having the three states of High level, Mid level and Low level and by this ternary code, tracks are wobbled so as to multiplex the frequency of the digital audio signal. Thus, intermodulation between the video signal and the audio signal is reduced and there is no adverse influence upon the video signal.
