Title: Disk-like recording medium and its recording/reproducing device
Inventor: OGA NORIO
IPC: G11B11/105
Filed: 1990-08-23
Abstract: PURPOSE:To miniaturize this recording/reproducing device without reducing data capacity by forming recording tracks with about 1.6 mum track pitches on a disk having a diameter <= 80 mm and recording the specific quantity of information on the recording tracks in a data-compresed state. CONSTITUTION:Recording tracks W with about 1.6 mum track pitches are formed on the disk 1 having the diameter D <= 80 mm and information >= 130 M bytes is recorded on the tracks W in the data-compressed state. When an audio signal e.g. is A/D converted into a digital signal consisting of 16 bits per sample at 44.1 kHz sampling frequency, audio signals for two channels can be recorded/ reproduced for 60 minutes or more by compressing the digital audio data into 1/4. Thus, the device can be miniaturized without reducing its recording capacity.

Title: Guide vehicle
Inventor: TANGE TOSHIAKI
IPC: G05D1/02
Filed: 1991-09-02
Abstract: PURPOSE:To avoid fixing a transfer route by controlling the driving device and the manipulation actuator of a vehicle with use of a controller which is controlled by the output signals received from a homing device and a distance meter. CONSTITUTION:A homing device 1 detects an error between the right and left directions of a preceding traveling object, and a distance meter 2 detects an error between the front and back directions of the preceding object respectively. The front-back reference distance is set according to the size and the application purpose of each vehicle. A controller 3 calculates the correction value of both direction and distance based on the signals outputted from the device 1 and the meter 2. Then the controller 3 starts a manipulation actuator 7 to the direction and steers the rear wheels and also controls an electric motor 5 and an electromagnetic clutch/brake 6 of a driving device 4 to keep a proper distance. In such a constitution, the transfer route is not fixed for the vehicle. Thus the man power can be reduced and the flexible performance can be improved.

Title: Optical displacement detection apparatus
Inventor: KUROKI SHINGO
IPC: G01D5/244
Filed: 1992-07-29
Abstract: PURPOSE:To obtain an optical displacement detection apparatus whose resolution is high and which can comply with a high speed operation by a method where, when a latch signal is inputted, a sine-wave output in a phase which obtains the output at this point of time, is latched so as to be maintained. CONSTITUTION:A plurality of photodetectors 120a to 120d receive beams of light which are limited by a reference grating 116 and detection gratings 114a to 114d, and they output relative movement amounts of a main scale and an index scale as a plurality of sine-wave signals whose phase is different from each other. In addition, phase-dividing circuits 162a to 162j divide the phase difference of outputs of the elements 120a to 120d into a plurality of phase differences, and they outputs a plurality of sine waves whose phase difference is very small. Then, when a latch signal is output, a latch circuit latches the sine waves in the phases which obtain the output at this point of time so as to be maintained. Consequently, when the latch signal is input to the latch circuit after a positioning operation, the output from this point of time becomes the sine-wave signal, and it can be returned immediately to an original positioning state.

Abstract: PURPOSE: To improve the antistatic effect and lessen the number of part items of a cathode-ray tube by earthing the cathode-ray tube by electrically connecting a conductive adhesive layer of a resin leakage preventive tape and an explosion- proof band and electrically connecting the explosion-proof band with the surface or a resin layer of safety glass through the adhesive layer. CONSTITUTION: In a CRT 30, a panel glass 32 and a funnel glass are fused and united with flit glass. Safety glass 36 is stuck to the front face of the glass 32 through a resin layer 34. The resin layer 34 is made of unsaturated polyester resin, etc., having conductivity. In order to prevent the unsaturated polyester resin composing the resin layer 34 from leaking out of a gap between the safety glass 36 and the panel glass 32, a leakage preventive tape 38 is wound on the circumference of the resulting body to stick the glass and resin layer mutually. The tape 38 is composed of a substrate tape 38a and a conductive adhesive layer 38b. An explosion-proof tape 40 is so wound on the side wall of the panel glass as to overlap a part of the tape 38 and stuck to the side wall.  Then, after heated, an explosion-proof band 42 is wound on the outside of the glass 32 and cooled to fasten the glass and the band is connected with an earthing electrode at the time of installation of a TV set.

IPC: F04D3/00
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To pass an inclusion in a fluid in a center part of a fluid machine by arranging a fluid step difference part having a specified radius on a part of a static flow passage, and not having a fluid machine composing element in a specified range of a rotator. SOLUTION: When a control system 10 is passed from an outside current system 11 to a stator 4 lead current, a rotator 7 is rotated by a motor action between the stator 4 and a rotator 6. When rotation of the rotator 7 is started, the rotator 7 is moved by reaction. Since a flow passage step difference part 3 having a radius smaller than an outer peripheral radius R of a rotator is arranged on a part of a static flow passage, movement of the rotator 7 is restrained. A structure is not arranged in a range of 1/2 of the outer peripheral radius R of the rotator 7 from a rotary center of the rotator 7. A fluid and a part of solid which is included in the fluid can be passed without being brought into directly contact with the rotator.
