Filed: 1989-09-20
Abstract: PURPOSE:To detect the breakage of a mechanical seal on leaked oil receiving chamber side in its early stages by disposing an optical fiber sensor having an objective lens at its top end and a light source on the side wall of the leaked oil receiving chamber and a reflecting plate on the bottom of the receiving chamber. CONSTITUTION:An objective lens 31 is mounted on the top end within a leaked oil receiving chamber 16b of an optical fiber sensor 31 in opposition to the oil detecting surface 36 of a reflecting plate 35 provided on the bottom part of the chamber 16b. A light source 34 such as lens is provided in the end within the chamber 16b of the optical fiber 33 to irradiate the oil detecting surface 36.

Title: Character recognizing method
Inventor: HOZUMI YOSHIKO
IPC: G06K9/46
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To recognize a character with high precision even from a character image which is of small size or has illuminance spots or deformation and to precisely recognize characters from character images of many kinds of type without using many dictionaries corresponding to the types. SOLUTION: A recognizing processor 2 to which this method is applied generates outline data of image data inputted from an image input device 1 such as a digital still camera and matches the data obtained by normalizing the outline data (including enlargement, reduction, etc., of data) against dictionary data prepared by extracting outline data of standard characters registered in a storage device 4 to perform character recognition. At this time, the outline data of the image data are deformed into a type to be recognized with the dictionary data or deformed so as to have distortion corrected depending upon the type, distortion, etc., of the input image data. Consequently, even an image which is of small size or has illuminance spots or deformation can be recognized with high precision and precise character recognition of character images of many kinds of type can be performed only with e.g. a dictionary corresponding to one kind of type.
