Title: Method and device for reading mark
Inventor: OZAWA TATSURO
IPC: G06K7/00
Filed: 1990-01-22
Abstract: PURPOSE:To easily and surely discriminate a formal mark from the false one by activating successively plural light emitting elements which have their peak wavelengths in plural wavelength areas where the different spectral reflectivities are produced by a mark and calculating the differences among intensity data on the reflected beams of each light emitting elements in order to discriminate those marks from each other. CONSTITUTION:At least two light emitting elements 3 and 4 are prepared and have their peak wavelengths in plural wavelength areas where the different spectral reflectivities are produced from a mark 2. Then these elements 3 and 4 are successively activated, and the difference is calculated between the intensity data on the reflected beams of both elements 3 and 4. A formal mark is decided if the difference between both intensity data is equal to a prescribed level. Meanwhile a part other than the mark is decided if the difference is less than a fixed level. In such a way, a formal mark is easily and accurately discriminated from the false one.

Title: Spherical click spring for push switch
Inventor: KANAZAWA HIRONOBU
IPC: H01H13/52
Filed: 1995-01-27
Abstract: PURPOSE: To enhance the durability and reliability of a push switch by preventing formation of burr at the outer edge of a spherical click spring for use as the movable contact of the push switch. CONSTITUTION: Holes 14 are punched through a plate-spring hoop 11 and opposite to each other to form a disc portion 15 and runner portions 16 on both the right and left sides of the disc portion 15. The disc portion 15 has rectilinear portions 17 formed on both the right and left sides, and the center of each rectilinear portion 17 is connected to the periphery 18 of the hoop 11 by the runner portions 16. The disc portion 15 is press molded into a dome shape to mold a spherical click spring 13, which is then separated from the hoop 11 by cutting the runner portions 16 by means of an automatic cutting machine.  Even if the cutting position is more or less varied, cutting is performed within the range of the rubber portions 16 without the possibility of the main body of the spherical click spring 13 being cut at its outer edge, so that formation of such a spherical click spring as having burr on the bottom surface of its outer edge serving as the surface of contact with a base can be prevented.

IPC: G06K9/36
Filed: 1986-01-24
Abstract: PURPOSE:To attain high speed processing by providing an address selection means for selecting an input density value as a reading address to a memory and the density value outputted from an input register means as a writing address. CONSTITUTION:A correction value table 132 generates an addition value of one input supplied from comparators 1311-131n. During the input of a picture element IP, when the are m input picture elements of the same density value as the picture element IP in the n input picture elements processed in a pipe line arithmetic means 140, the correction value goes to m+1 and is added to the pipe line arithmetic means 140. Based on the contents S of the memory inputted from a memory register 170 and the correction value m+1 inputted from the correction value table 132, an arithmetic processing for outputting 'S+m+1' is carried out. The address selection means 150 selects the density value of the picture element IP of the register means 121n and stores the density histogram 'S+m+1' stored in arithmetic registers 143n and 144n as the writing address in a memory 110. Thereby, the high speed processing can be performed with a small scale and unexpensive constitution.

Abstract: PROBLEM TO BE SOLVED: To provide a substrate treatment apparatus capable of reducing the probability generating the sudden trouble of a drive part. SOLUTION: The standard operation time of a drive part 72 is set as a reference operation time 'tr ' to be stored in a memory 10. Next, a robot control part 70 measures the actual operation time 'tp ' of the drive part 72 by using a sensor 74 and a soft timer 71. A comparison part 51 calculates the difference td =tr -tp between the reference operation time and the actual operation time. Thereafter, a judge part 52 judges whether the difference 'td ' between the reference operation time and the actual operation time is larger than a preset threshold value 'tth '. When 'td ' is larger than 'tth ', a main control part 50 displays a message to the effect that trouble is announced previously on a display 12. When 'td ' is not more than 'tth ', the measurement of the actual operation time is again continued.
