Title: Device and method for measuring variation of diameter of axially elongated essentially cyrindrical body
Inventor: MERUBIN UORUTAA SHIIGERU
IPC: G01M11/00
Filed: 1990-08-29
Abstract: PURPOSE: To accurately measure fluctuations in the diameter of a moving strand by allowing laser beam to impinge against the moving strand to generate diffraction and interference patterns to detect them by a DCD and calculating the diameter of the strand on the basis of the output of the CCD. CONSTITUTION: Two or more pairs of lasers 4 and CCDs 5 are arranged in the detection chamber 8 of a measuring apparatus 1 at known angular positions. A moving strand 9, for example, a moving glass fiber is inserted into the detection chamber 8 to be aligned with the center line of the chamber. Subsequently, radiations are allowed to impinge against the strand 9 from the respective lasers 4 to generate diffraction and interference patterns which are, in turn, detected by the mutually opposed CCDs 5. The detection signals are subjected to analogue/digital conversion to be transmitted to a memory control panel and predetermined calculation is performed by a computer to calculate the diameter of the strand. Therefore, the diameter of the moving strand can be accurately measured and this method is usefully used in fiber industry relation.

Title: Character reader
Inventor: SHIMIZU YASUHIKO
IPC: G06K9/68
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a character reader which can shorten the process time and improve the recognition rate. SOLUTION: When image data of a 1st character frame recognized by a character recognition part 15 are, for example, 'TAISHO', a select signal SEL for selecting a character set 16a for recognition of a 2nd character frame is outputted from a character set selection part 17 to a character dictionary 16A. Then the image data of the 2nd character frame are segmented by a character segmentation part 16 and supplied to the character recognition part 15, which performs character recognition according to the character set 16a for recognizing only numbers '0' and '1'. When the 1st character frame is 'SHOWA', the 2nd character frame has its characters recognized according to a character set 16c for recognizing numbers '0' to '6'. Thus, the recognition is performed by limiting character candidates according to the recognition result of a previous character frame, so the processing time is shortened and the recognition rate is improved.

IPC: H01J7/24
Filed: 1985-10-16
Abstract: PURPOSE:To minimize the luminance reduction of the picture screen and the deterioration of the phosphor by cooling so as to improve the reliability of a projection cathode-ray tube by packing a cooling medium whose optical refractive index is equal to that of the panel glass into the central concave area on the outer surface of the panel of the cathode-ray tube. CONSTITUTION:The inner surface of the panel 11a of a projection type cathode- ray tube is made convex to form a phosphor face 12, and the outer surface of the panel 1a is made concave so that the panel glass surface may be of uniform thickness. A front panel 2 is installed in front of the tube 1a, and a cooling medium 3 whose optical refractive index is equal to that of the panel 11a is packed between the panels 2 and 11a. Therefore, the heat produced in the fluorescent screen 12 is transmitted to the cooling medium 3 through the outer surface of the panel 11a thereby reducing the temperature increase of the central area of the fluorescent screen 12. As the result, the luminance reduction of the picture screen or the deterioration of the phosphor hardly occurs thereby increasing the reliability of the cathode-ray tube 1a.
