Title: Binarization method for density image and image binarization device
Inventor: HONMA TORU
IPC: G06V30/162
Filed: 1995-06-23
Abstract: PURPOSE: To determine an optimum binarization threshold for an original image by determining the binarization threshold according to features of the density distribution of pixels in an extracted edge area and carrying out the binarization of the original image. CONSTITUTION: The density distribution in the extracted edge area is found. Namely, to find the binarization threshold between the density values of two pixels whose difference is calculated when the edge is found, the density distribution is so found that the density values of the two pixels are interpolated. At this time, after a differential value to each density value of the density distribution of a pixel in the edge area which indicates the extent that the binarization threshold at the time of the binarization of the original image P1 is present between the density values of the respective pixels is found on the basis of the large/small relation between the density values of the two adjacent pixels in the edge area, all density values in the edge area are integrated to find the density distribution in the edge area.  Consequently, a histogram (density value in edge area) of density values of the pixels in the edge area extracted from the original image P1 is obtained, and in this density distribution, the density value which has a nearly maximum distribution value is the binarization threshold value Q1.

Title: Optical communication system between processors
Inventor: MURAKAMI KOUZOU
IPC: H04B10/07
Filed: 1983-08-31
Abstract: PURPOSE:To prevent collision at a transmission time by judging that the other- party processor is not communicating if an optical signal level is lower than a prescribed level and controlling an optical matrix switch to enter into the transmitting operation. CONSTITUTION:In case of transmission from a processor CP1 to a precessor CP3, whether the level of an optical signal D1 inputted to an optical signal detection input terminal of the processor CP1 is a rescribed level or not is judged. If this optical signal is lower than the prescribed level, the processor CP1 discriminates that the processor CP3 is not communicating, and the processor CP1 outputs a control optical signal which controls an optical switch S13. Thus, an input optical signal IN1 transmitted from the processor CP1 to an optical matrix switch MSW is transmitted to the processor CP3 in the reception side through optical switches S11 and S12 of the through mode, an optical switch S13 of the branch mode, and optical switches S23, S33, and S43 of the through mode.

IPC: G06F9/38
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce the waiting time of a cache access request by suppressing data cache access only when all block load data are continuously written to a data array. SOLUTION: A target data bypass control circuit 25 writes target data to a general purpose register through 1st and 2nd bypass paths. A data array write control circuit 26 writes subsequent data to a data array 22 when a data buffer holds all data that are sent by a main storage device. When a main storage access instruction is a cache miss, block load data which are sent due to the cache miss by the main storage device 4 are sequentially held, during this time, target data in the block load data are sent externally, and after that, data cache access is suppressed only while all block load data are continuously written in the data array.

Title: Joining device for foil material and method therefor
Inventor: WILD HANS-PETER
IPC: B31B50/64
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a joining device of a foil material and a method thereof which permits a joining head to rapidly lift up and down, and prevent the foil material from being burned or damaged in all the operational states. SOLUTION: A joining head 24 is directly mounted on foil materials 2, 4 at the joining position to perform the foil joining operation. While the foil materials 2, 4 are transferred, the joining head 24 is located in the intermediate position spaced apart a distance Y from the joining position of the joining head 24. The distance Y is set in the shortest one, so as to avoid the waste of time caused by the shift of the joining head 24. When the joining device is not transferred at an enough speed, the joining head 24 is located in the non-operational position having a larger distance X than the distance Y from the joining position of the joining head 24, thereby preventing the foil materials 2, 4 from being overheated or burned.

Title: Method for measuring warping of plate
Inventor: SAKAI SEIYA
IPC: G01B5/20
Filed: 1989-06-21
Abstract: PURPOSE:To exclude the substantial weight of a plate itself and to make it possible to measure the warping of the industrial plate at a high measuring sensitivity by supporting the plate to be measured with a slant plate, and measuring the warping of the plate with respect to the slant plate. CONSTITUTION:A stand 2 is provided on a stage plate 1 having wheels. A slant plate 3 is supported on the stand 2 through a shaft 4 so that the plate can be freely rotated. An angle adjusting holder 5 is attached to the slant plate 3. When a setting bolt 6 is inserted into a specified angle-adjusting hole, the slant plate 3 can be fixed at the desired angle. Stoppers 7 and 8 are attached to the lower end and the one side of the slant plate 3. A plate to be measured P is mounted on the slant plate 3. The lower end of the plate is supported with the lower end stopper 7 of the slant plate 3. The angle of the slant plate 3 is gradually increased by the manipulation of the setting bolt 6. When the angle of the slant plate 3 comes close to 90 deg., the upper part of the plate is separated from the slant plate 3, and the forward bending state is obtained. The measured value is affected by the bending moment of the weight of the plate itself. Therefore, the slant angle of the slant plate is set at 30 deg. or less.
