Patent number: 5162714Abstract: A numerical control device adapted to control a plurality of transfer machines mounted on a transfer line. The numerical control device is composed of an NC section (13) for controlling the axes of the transfer machines and a PMC section (14) for executing sequence control. The PMC section (14) reads current position data from a current position register (16) of the NC section (13) through a window, and compares the read data with previously set zone data (19). A function instruction (18a) delivers the result of the comparison as a zone signal, and executes a modification control of an execution sequence by using the zone signal. Therefor, a high-accuracy region signal can be set.Type: GrantFiled: October 23, 1990Date of Patent: November 10, 1992Assignee: Fanuc Ltd.Inventors: Yoshiaki Ikeda, Nobuyuki Kiya, Shoichi Otsuka

Picture processing apparatus including data conversion table for performing convolutional processing
Patent number: 5063525Abstract: A picture processing apparatus inputs window data (W) to look-up tables (TBL) in which operators (G or F) to be applied to pixel data (x) are stored in correlation to the locations of the pixel data. By switching between the operators (G or F) contained in the look-up tables (TBL), window processing corresponding to a data address (i,j) is performed on input pixel data (x.sub.ij).Type: GrantFiled: July 9, 1990Date of Patent: November 5, 1991Assignee: Fanuc Ltd.Inventors: Mitsuo Kurakake, Shoichi Otsuka, Yutaka Muraoka -
Patent number: 4945496Abstract: A picture processing apparatus uses coefficient matrix data to perform convolution processing on a time-sharing basis with regard to each item of pixel data of a frame memory (3) which stores plural items of pixel data. When such processing is being performed, the results of addition from the adder (5) are delayed a predetermined period of time by delay device (7), thereby assuring that intermediate processing results may be written in the buffer (9) with certainty. At the same time, a read-out address of the buffer (9) is revised by an amount equivalent to the delay in the write timing, thereby making it possible to speed up the time-sharing convolution processing.Type: GrantFiled: November 25, 1987Date of Patent: July 31, 1990Assignee: Fanuc LtdInventors: Mitsuo Kurakake, Shoichi Otsuka, Yutaka Muraoka

Patent number: 4890100Abstract: The present invention is directed to a picture processing apparatus for painting a picture memory of a CRT display unit or similar apparatus by paint data. In accordance with this picture processing apparatus, a dual-port memory (4) is used as a frame buffer for storing picture information. In order to store paint information in a memory cell array (7), the information is internally transferred from predetermined storage circuit (9) via a data register (8) having a serial input function. The number of times the dual-port memory (4) is accessed from the processor (1) is greatly reduced so that the burden on the processor (1) can be alleviated. It is also possible to shorten the time required for the paint information to be stored in the memory cell array (7).Type: GrantFiled: September 1, 1987Date of Patent: December 26, 1989Assignee: Fanuc Ltd.Inventors: Mitsuo Kurakake, Shoichi Otsuka, Yutaka Muraoka

Patent number: 4852024Abstract: A cathode ray tube (CRT) controller (6) reads out a predetermined picture from a frame memory (2) storing a picture to be processed, and generates a bit pattern with respect to a window memory (5), having a size corresponding to the frame memory (2) and storing a bit pattern which specifies the validity or invalidity of picture processing. The pattern output by the CRT controller (6) controls the processing of the frame memory (2), so that picture processing is executed solely with respect to picture data in an area of the frame memory (2) specified by the bit pattern.Type: GrantFiled: April 10, 1987Date of Patent: July 25, 1989Assignee: Fanuc Ltd.Inventors: Mitsuo Kurakake, Shoichi Otsuka

Patent number: 4837487Abstract: A system for coupling a visual sensor processor (B) and a robot controller (A), so that the processing of the whole system is sped up and the configuration of the system is low-cost. To this end, the visual sensor processor (B) and the robot controller (A) are coupled together via a bidirectional high-speed data transfer channel (10, 28, l.sub.1, l.sub.2) for an exchange therebetween of required information. A nonvolatile memory (6) and a serial interface (12) for connection to an external input/output device, are installed in the robot controller (A), and are shared by the visual sensor processor (B) and the robot controller (A) through utilization of the channel.Type: GrantFiled: October 26, 1987Date of Patent: June 6, 1989Assignee: Fanuc Ltd.Inventors: Mitsuo Kurakake, Hideo Miyashita, Shoichi Otsuka

Patent number: 4811098Abstract: In a picture processing apparatus, a front porch time (FP) conforming to a picture signal from a particular picture input unit (2) is stored beforehand in a register (R) by a host computer (8). When the picture input unit (2) outputs a horizontal synchronizing signal (HSYNC), the front porch time (FP) from issuance of the horizontal synchronizing signal (HSYNC) until the beginning of a significant picture information interval (PCPD) is calculated by referring to the register (R) and counting down the value from the register. The picture information is then introduced into a picture memory (6) from the calculated beginning of the significant picture information interval (PCPD). The picture processing apparatus may be used for a variety of different picture input units, as the host computer stores the front porch time corresponding to the particular picture input unit to be used in the register (R) prior to picture processing.Type: GrantFiled: January 27, 1988Date of Patent: March 7, 1989Assignee: Fanuc Ltd.Inventors: Mitsuo Kurakake, Shoichi Otsuka, Yutaka Muraoka

Patent number: 4747157Abstract: The present invention is directed to an arithmetic which calculates the spatial product sum of each of a plurality of picture element data stored in a frame memory, through utilization of load coefficients with N rows and N columns stored in a coefficient memory. The results of calculation for pieces of picture element data of one row of the frame memory and load coefficients of one row are added to the contents of shift registers corresponding to picture elements. This operation is repeated N times for different rows of the frame memory and different load coefficients. Thus, the spatial product sum calculation is performed at high speed using a small number of multipliers.Type: GrantFiled: December 3, 1986Date of Patent: May 24, 1988Assignee: Fanuc Ltd.Inventors: Mitsuo Kurakake, Shoichi Otsuka
