Title: Picture processor
Inventor: NAKAMOTO HIROSHI
IPC: G06T7/60
Filed: 1990-05-11
Abstract: PURPOSE:To increase the processing speed by collating the start position of a pattern to be processed and that of a reference pattern with each other at the time of input of a picture to perform the pattern matching inclusing the positional deviation correction in one frame period of the input picture. CONSTITUTION:The reference pattern is preliminarily stored in a picture memory 21, and coordinates of the head position are set to an address generator 33. When the pattern to be processed is inputted, a start position detecting circuit 31 detects coordinates of the head position and outputs them to the generator 33. The generator 33 generates an address from coordinates, and the reference pattern is read out of the memory 21 synchronously with the input of a binary picture signal, and the number of disaccording picture elements detected by an exclusive OR circuit 26 of a pattern matching circuit 28 is counted by a counting circuit 27. Thus, the pattern matching including the positional deviation correction is performed in one frame period of the input picture, and the processing speed is increased.

Filed: 1986-05-27
Abstract: PURPOSE:To perform thin or thick spray painting, by providing a valve body for opening and closing the paint passing hole of a valve seat, a means for reciprocally moving the valve body and a paint control means for regulating the reciprocating moving quantity of the vale body to a body part. CONSTITUTION:A valve body 14 having a piston 17 moves to the left to contact with a valve seat 13 and a head part 15 closing a paint passing hole 13a is separated from the valve seat 13 to open the paint passing hole 13a. Because the compressed air injected from an air nozzle 5 passes through a spray orifice 2a at a high speed, negative pressure is generated in a spray nozzle 2 and paint is sucked from a paint inlet 12 through the paint passing hole 13a by said negative pressure to be injected from the spray orifice 2a as particles. The gap between the air nozzle 5 and the inner wall surface of the nozzle 2 is held by holding an air pipe 4 to a head part 1 and the spraying of high viscosity paint is performed continuously and uniformly.

Title: Slit inspection instrument
Inventor: NAKASHIRO MASAHIRO
IPC: G01B11/14
Filed: 1989-05-16
Abstract: PURPOSE:To accurately measure a slit width even when the light quantity of a light source varies by denoting light outputs of a three-split photodetector as A, B, and C, and detecting a slit position from (A+C)/B. CONSTITUTION:The light source 1 emits nearly parallel luminous flux. The slit 2 to be measured is formed by sticking metal such as Al and Cr on a transparent body of glass, vinyl, etc., and removing part of it. A life-size optical system is constituted by setting the focal length of a convex lens 3 to, for example, 15mm, setting the slit 2 and the three-slit photodetector 4 at an interval of, for example, 60mm, and installing the convex lens 3 at an equal distance. At this time, an image of the same size with the slit 2 is formed on the photodetector 4. An arithmetic circuit 5 outputs (A+C)/B, where A, B, and C are the outputs of three elements of the photodetector, so as to standardize variation in the quantity of light source light and if the value is larger or smaller than an upper-limit or lower-limit threshold value, the slit width is abnormal, so the slit is checked as a defective.

Title: Displacement detector
Inventor: NIWA TAKASHI
IPC: G01B7/00
Filed: 1988-05-19
Abstract: PURPOSE:To enable the setting of a reference point at a desired position even when the adjustment of a fixed position of a detector is rough, by providing first and second reference point input means to allow the setting of the reference point both in hardware and software modes. CONSTITUTION:After a displacement detector is mounted securely, a reference point is set by a first reference point input means 3 when an actuator 47 is moved to reach a specified position. As the input means 3 is made up of a contact switch, even when the actuator 47 is shifted during a power failure, the reference point is obtained again by said reference point input means 3 to allow the correction thereof in a correction position display. After the detector is fixed securely, when the actuator 47 is moved to reach a desired position, an input is applied by a second reference point input means 36, thereby permitting the setting of the position as software-oriented reference point.

Filed: 1982-07-14
Abstract: PURPOSE:To use both sides of an electronic blackboard, by arranging rotatably the blackboard and returning a detecting signal from a control circuit to the control circuit only when one side is used, to detect the using side of the board. CONSTITUTION:The board B is set up rotatably on an unshown supporting board by an axis AX and connectors CN1, CN2 are fitted to both the upper and lower ends. These connectors CN1, CN2 are selectively connected to a connector CN connected to a control circuit CONT. Two terminals of the connector CN2 are shorted to return a detecting signal from the control circuit CONT. The control circuit CONT detects whether the using side is B1 or B2 according to the presence of the return of the detecting signal. When the side B2 is in using, the Y coordinate is converted by YA=YL-YC. (where YA=real Y coordinate, YL=the whole length in the Y direction, YC=Y coordinate from a sensor). Consequently, transmission of the coordinate to the opposite by using both sides, CRT display and storage in a floppy disc can be precisely performed.

Abstract: PURPOSE:To record only a required voice message part with simple and inexpensive constitution when a voice message is recorded by remote control by erasing a recorded part going back by a prescribed time from a final recording area recorded by a current recording when the recording is stopped. CONSTITUTION:A control section 11 calculates a time from the reception of a recording stop signal till a recording and reproducing section 15 is stopped and erases an area recorded by a recording and reproducing section 15 for the time and transits to the succeeding control. Thus, a recording stop signal is recorded once to the recording and reproducing section 15 but the recording is immediately erased. Moreover, the time till the control section 11 stops the recording and reproducing section 15 after the reception of the recording stop signal is almost constant, the recording and reproducing section 15 is stopped and the recorded part in the past going back by the prescribed time from the area of final recording is erased. Thus, when a voice message is recorded by remote control, only the required voice message is recorded simply with inexpensive constitution.
