Title: Pwm system a/d converter
Inventor: AOKI CHIHARU
IPC: H03M1/50
Filed: 1989-07-28
Abstract: PURPOSE:To remove off-set from the output of a PWM integrator and to improve accuracy for an A/D converter by dividing the frequency of a clock, which passes a photocoupler and generates the off-set, by a frequency dividing circuit in a simple configuration and executing waveform shaping. CONSTITUTION:The frequency of a reference clock E to be generated from a reference clock generating circuit 6 of a digital part 2 is made double to a frequency required as a clock for measurement. In an analog part 1, a two- frequency dividing circuit 12 is newly provided between a buffer amplifier 7 and a resistor R2. The frequency of the reference clock E to be inputted to a photocoupler 5 is made double to a conventional example (namely, a half period is T/2.) After transmission by the photocoupler, the waveform in a B point is rounded samely as the conventional example and the duty of the clock through the buffer amplifier 7 is deviated from 50%. However, since the frequency of this clock is divided into two by the two-frequency dividing circuit 12 composed of a T type flip-flop and the waveform is shaped, the clock for measurement (waveform in a D point) can be obtained with the deisred period (2T) and duty 50%.

Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide an optical probe which may be mass produced and has good light condensability by specifying the width and thickness of an optical waveguide in which a beam propagates in the exit part of the beam propagating in the plane type optical waveguide to the wavelength of the beam in air or below as well as an optical disk device and the production of an optical probe. SOLUTION: The optical probe is obtd. by providing an LiNbO3 , film 2 of a ferroelectric material formed by epitaxy on a sapphire substrate 1 with an incident part 24 and the exit part 25. The beam propagating in the plane type waveguide is made smaller than the wavelength in the air in width and thickness directions, respectively, and this beam is radiated from the exit part. Since a very small light spot may be formed at the optical waveguide of a flat plate type, the optical probe having the excellent reproducibility and cost may be constituted by using the semiconductor process. A higher density and mass production may be attained with the optical disk device using the same.

Title: Gps receiver
Inventor: TAKARA YUJI
IPC: G01S5/02
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To provide proper mode position measurement information by automatically returning the set to AUTO position measurement and displaying it when three-dimensional position measurement is possible in spite of the setting of two-dimensional position measurement, or only the two-dimensional position measurement is possible in spite of the setting of three-dimensional position measurement.

When a more precise three-dimensional position measurement is possible from the number or arrangement of GPS satellites even when two-dimensional position measurement is set by a DGPS(differential global positioning system), the set mode is automatically changed to AUTO position measurement, and a display showing the position measurement mode at the present point of time is added to a position measurement mode setting and display part 11. When three- dimensional position measurement is difficult even when three-dimensional position measurement is set by the DGPS, the set mode is automatically changed to AUTO position measurement, and a display showing the position measurement mode at the present point of time is added to the position measurement mode setting and display part 11.

Title: Disk cleaner device
Inventor: SATO TAKASHI
IPC: G11B23/50
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To miniaturize a disk cleaner device by attaching a polisher for polishing the surface of a disk and a motor for driving the polisher to a casing. SOLUTION: A compact disk 8 is placed on a turntable 6 and, by turning a switch 16 ON while a lid 2 is closed and a polisher 14 and the compact disk 8 are in contact with each other, the polisher 14 is rotated. Following the rotation of this polisher 14, the turntable 6 and the compact disk 8 are associatively moved and this movement is a rotational motion around a main spindle 4. Thus, assuming that the circumferential speed of the polisher 14 and the speed of the outer peripheral part of the turntable 16 are coincident with each other, since the compact disk 8 is rotated at a speed different from the circumferential speed of the polisher 14 in any position, friction is created between the entire surface of the compact disk 8 and the polisher 14, and the compact disk 8 is polished.

Title: Signal input method
Inventor: TANIZAKI TOSHIMASA
IPC: G05B23/02
Filed: 1993-08-13
Abstract: PURPOSE:To surely detect the faults, to reduce the influence to a control operation, and to improve reliability of the device. CONSTITUTION:The signal groups 11 and 12 having a prescribed relation among signals are sent to a control part 30 via an input part 20 and then transmitted via an output part 40. A fault detecting part 50 detects a fault when a prescribed relation is not secured among the signals of the same signal group. The input signals 11a, 11b and 12a, 12b of both groups 11 and 12 are distributed and inputted to the different input circuit groups 21a and 22b respectively. If one of both groups 21a and 22b has a fault, only one of both signals belonging to the same input signal group becomes abnormal. Thus the part 50 can detect a fault. Furthermore the influence can be reduced to the part 30 owing to a fact that only one of both signals of the same group becomes abnormal.

IPC: G01N27/26
Filed: 1982-11-19
Abstract: PURPOSE:To obtain a sharp and clear fraction pattern, by subjecting a specimen to the electrophoresis, fractionating a phospholipid in a lipoprotein, and reacting a novel dyeing reagent with the fraction to develop a color.
