Title: Optical disk, reproducing device and duplicating device thereof, and method for preventing illegal use thereof
Inventor: TOZAKI YOSHIHIRO
IPC: G11B19/04
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a means capable of effectively preventing an illegal use of a DVD disk and other optical disks accompanied with a copyright infringement. SOLUTION: When reproducing data information of a DVD disk 1, a DVD reproducing device judges whether or not the data information is protected by a copyright based on disk management information, and judges whether or not the DVD disk 1 is a recordable one based on the presence or absence of the wobble of the DVD disk 1. Thus, when the data information is protected by the copyright and the DVD disk 1 is a recordable one, this device is arranged so as to be able to effectively prevent an illegal use of the DVD disk 1 accompanied with a copyright infringement, by inhibiting reproduction of the DVD disk 1.

Title: Rotational angle detector
Inventor: HISADA YASUMASA
IPC: G01D5/245
Filed: 1989-12-01
Abstract: PURPOSE:To accurately detect an angle of rotation by setting the detection voltage of a 2nd magnetic detector above or below a specific voltage when a magnet passes on a couple of magnetic sensing elements of a 1st magnetic detector by the rotation of a rotating body and its detection voltage crosses a reference voltage value. CONSTITUTION:The 1st magnetic detector (a) obtains the detection voltage V1 when the magnet 21 passes through the magnetic sensing(MR) elements 22 and 23. The 2nd magnetic detector (b), on the other hand, operates similarly, but the MR elements 25 and 26 deviate in arrangement, so their detection voltage V2 is out of phase by almost 90 deg.. For the purpose, the voltage V2 is compared with a constant voltage Vref to detect a range where the constant voltage is exceeded, and a detection permission signal is generated in the range. Then when the permission signal is generated, the point of time when the voltage V1 crosses V0 is measured and it is decided that the observation point is the passing point of the magnet 21. Therefore, when the detector (a) performs detection, the detection result is judged from the detection state of the detector (b). Namely, when the output V1 crosses the voltage value V0, it is confirmed that the output V2 is larger than the voltage Vref.

Title: Material to be recorded
Inventor: AEBA TOSHIAKI
IPC: B41M5/52
Filed: 1986-12-25
Abstract: PURPOSE:To enhance an image in resistance to light when a silica-containing material to be recorded having a low resistance to light is used, by a method wherein a silica previously treated with a water-soluble resin is contained on/in a surface to be recorded. CONSTITUTION:A silica previously treated with a water-soluble resin is contained on/in a surface to be recorded, and the water-soluble resin is a polyvinyl alcohol or the derivative thereof. The water-soluble resin is used in the ratio ranging 0.1-100 pts.wt. to 100 pts.wt. of the silica to be treated therewith. The use of less than 0.1 pts.wt. of the water-soluble resin results in an insufficient effect; that of more than 100 pts.wt. undesirably results in the reduction in ink absorption and color properties of a material to be recorded. In this manner, with the use of the silica previously treated with the water-soluble resin, a superior material to be recorded satisfying all the ink absorptions, color properties, and resistance to light can be obtained.

IPC: H01J9/02
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of Ag colloid in glass occurring at the time of baking, prevent discoloration, and improve the insulation property between electrodes by using the sheet glass manufactured by the pull-up method or pull-down method as a glass substrate when the electrode is formed with a conductor material containing Ag on the glass substrate.

For the back board, an address electrode is formed on the glass substrate by the screen-printing of a Ag printing paste and baking, for example. For the front board, a bus electrode is formed on a maintaining electrode, such as an ITO formed on the glass substrate with a conductor material containing Ag. The glass does not contain Sn reacted to Ag as a reducing agent as purities on the surface, unlike the soda lime glass manufactured by the float method.

Title: Control method for optical disk device
Inventor: GOMI AKIHIRO
IPC: G11B7/085
Filed: 1988-12-12
Abstract: PURPOSE:To accurately seek a target track even at the time of disturbing a signal due to a prepit by monitoring the variation of a speed error signal and judging it to be an erroneous signal to correct the track counted result at the time when this signal satisfies a prescribed condition. CONSTITUTION:A track counting means 10 counts the number of left tracks by the signal of an optical head 1, and a target speed generating means 2 reads out a target speed and outputs it to a speed error detecting means 4. Meanwhile, a speed detecting means 3 reads out the speed in accordance with the measured track passage time and outputs it to the means 4. The means 4 obtains the difference between the target speed and the detected speed and outputs it as the speed error. A speed error comparing means 7 compares this speed error with the preceding speed error in a storage means 8; and when the variation is larger than a prescribed value, it is judged that the output signal of the optical head 1 is disturbed by a prepit and the track counted result is corrected. Thus, the target track is accurately seeked.

IPC: G01C19/5663
Filed: 1994-11-24
Abstract: PURPOSE: To obtain a piezoelectric oscillation gyro having good characteristics by leading out the electrode of a piezoelectric element conveniently without causing any trouble in the operation thereof. CONSTITUTION: A plurality of electrodes 14B, 14C are formed on the surface of a piezoelectric 14A mounted on each side of a rectangular prism oscillator 12.

Abstract: PURPOSE:To provide a seat belt, which becomes tens at the time of collision by an efficient and quick pull. CONSTITUTION:An installing lever 5 is supported by a shaft body 10 in a swingable manner so that the lever 5 is attached to a fixed bracket 2 on one side of a seat, and a buckle 3 is temporalily held at an end of the lever 5. A wire 6 combined with the buckle 3 is laid along the installing lever 5 and then pulled out from a lead-in hole 19 situated at the center of oscillation of the shaft body 10 to the rear surface of the bracket 2. Moving force in the direction of an arrow-mark (A) is given to the wire 6 by an energizing spring, but in usual case the movement of the wire 6 is prevented by an engaging/ disengaging unit 7. At the time of collision, engagement of the wire 6 is broken so that the buckle 3 is pulled. In this case, however, since the direction (A), on which pulling force of the wire 6 acts, coincides with the axial direction (B) of the buckle 3, no excessive component force acts on a lead-in point (P) of the buckle 3, and the buckle 3 is pulled straight.
