Patent JP-H0791965-A (JP)
Title: Optical fiber gyroscope
Inventor: TAKAHASHI HIROYUKI
IPC: G01C19/72
Filed: 1993-09-24
Abstract: PURPOSE:To reduce errors of angular velocity by a method wherein a DC level of an output of the angular velocity is calculated and a low pass filter output of the angular velocity is subtracted from the results to integrate the resulting substraction output. CONSTITUTION:Light radiated from a light source 1 is admitted into a sensing coil 6 as clockwise or counterclockwise rotated light through an optically directive coupler 2, a polarizer 3 and an optically directive coupler 4. The light rotated clockwise or counterclockwise is modulated in phase with a phase modulator 5 to be admitted into a photodetector 7 through the coupler 4, the polarizer 3 and the coupler 2. An electrical signal subjected to photoelectric conversion with the photodetector 7 is handled with a synchronous detector 8 using a signal supplied from an oscillator 9 as control signal to obtain an angular velocity output 13. By a subtracter 10, a low pass output passing through a low pass filter 11 is subtracted from the angular velocity output 13 to remove a DC level as bias contained in the angular velocity output 13. An output of the subtractor 10 is processed to be integrated by an integrator 12 to obtain the angular velocity output 14 with limited errors free from effect of the DC level.

Inventor: YOKOI TAKAAKI
IPC: H05K13/04
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To flexibly operate a production schedule by changing production items when the change of the products is decided by a production item change method, by means of the recognition of a product identification feature or the production number of products. SOLUTION: A product change deciding means 11 decides to change from the recognition results of a substrate feature storage means 10 and a recognition means 1. A product item change necessity deciding means 12 compares the decision result of the product deciding means 11 and a protect item storage means 9.

Title: Method for painting building material having deeply engraved rugged pattern
Inventor: MINEMOTO TAKASHI
IPC: E04C2/30
Filed: 1987-09-22
Abstract: PURPOSE:To form uniform coated films on the surface of a building material having deeply engraved rugged patterns by excessively coating a paint by means of a shower coater on the surface of said material, then blowing air by an air nozzle at 1-20 deg. injection angle with the perpendicular of the coated surface. CONSTITUTION:After the paint is excessively coated by the shower coater on the surface of the building material having the deeply engraved rugged patterns, the air is blown to the surface by setting the blowing angle to the surface at 1-20 deg. with the perpendicular thereof to remove the excess paint. The deeply engraved rugged patterns have >=1mm depth of the ruggedness 1. The paint is sufficiently stuck over the entire surface of the deeply engraved ruggedness 1, more particularly the perpendicular faces 1B, 1B and the base 1C as well at the time of excessively supplying the paint from the shower nozzle. The reason for setting the blowing angle theta of the air nozzle at 1-20 deg. with the perpendicular V is to execute the removal of the excess paint while allowing the uniform coated films to remain at the time of removing the excess paint.

Title: Finder display device
Inventor: HAYASHI KOTARO
IPC: G03B13/36
Filed: 1988-09-22
Abstract: PURPOSE:To allow a photographer to readily recognize an automatic focusing spot by using a hologram plate and displaying information on automatic focusing so as to overlap with an erect virtual image of an object that is focused automatically. CONSTITUTION:Plural light emitting elements 2A to 2E selectively emitting light to display the automatic focusing position are arranged outside a finder optical path. A hologram plate 3 arranged on the finder optical path diffracts the light from the light emitting elements and information on automatic focusing is displayed to overlap with the erect virtual image of the object that is automatically focused. Therefor, even if the virtual image of the object is formed ahead of the camera, hologram can surface the focused position display in the position where the virtual image is formed. Thus, an image of the object and the focused position display can be observed at the same diopter.

Title: Adhesive agent for optical disk
Inventor: OZAWA MASAHIKO
IPC: G11B7/24024
Filed: 1987-09-25
Abstract: PURPOSE:To prevent the flocculation of an adhesive agent for optical disks to be generated in the case of long-term preservation and to prevent the degradation in appearance by incorporating superfine particulate anhydrous silica into the above-mentioned adhesive agent.

Title: Vertical deflecting circuit
Inventor: IMAIZUMI NORIO
IPC: H04N3/23
Filed: 1984-11-13
Abstract: PURPOSE:To feed back a parabolic voltage and to supply a deflecting current of a high linearity to a vertical deflecting coil by connecting a capacitor and resistance connected serially to the vertical deflecting coil to input terminals of a vertical drive and output stage through the 1st and 2nd feedback loops. CONSTITUTION:An output from a vertical oscillator circuit 1 supplies saw tooth currents to the vertical deflecting coil 3, the DC inhibiting capacitor 4 and the resistance 5 through the vertical drive and the output stage 2, and a voltage inverted by an inverter/amplifier 6 appears in the output terminal of said circuit 1. On the other hand,the parabolic voltage appears in one terminal of the capacitor 4, added to said saw tooth current, and goes to a waveform, where the parabolic voltage and a saw tooth voltage are overlapped, at the input terminals of the drive and the output stage 2, whereby it is subjected to S-correction. When a variable resistance 15 is changed, the component of the saw tooth voltage is made larger or smaller, and therefore the component in the first half or latter half during a scan period can be lifted, whereby only the upper or lower part of a screen can be independently adjusted according to the lifted amount. Moreover, when the variable resistance is changed, the first or latter half during the scan period can be corrected.

Title: Servo-device of digital position
Inventor: SHIBATA NOBUHO
IPC: G05B19/23
Filed: 1983-12-19
Abstract: PURPOSE:To smooth the variation of a manipulated variable so as to smooth the rotation of a servomotor, by setting the frequency of a command pulse to 2<n> times of the frequency of a rotary encoder and commanding by using the set frequency as the low-order bit of a positional deviation. CONSTITUTION:When the (n) of an n-bit counter 6 is set to ''2'', the frequency fs of a command pulse is given as a frequency which is four times as large as the frequency fM of a detected pulse. The frequency fs is inputted into a counter 6 where it is reduced to 1/4 and the content of the counter 6 is taken into an arithmetic counter 2 as the lowest-order two bits of a positional deviation. On the other hand, the command pulse reduced to 1/4 is inputted into a positional deviation counter 1 where the deviation between the command pulse and the detected pulse is found and the found deviation is taken into the circuit 2 as the highest-order two bits. That is to say, a positional command is given as a resolution value which is 1/4 as large as the resolution of a rotary encoder 5. As a result, the changing quantity of the deviation taken into the circuit 2 while the deviation of the counter 1 changes by one pulse varies at every 1/4 pulse. Therefore, variation of a manipulated variable becomes smooth.
