Title: Method and device for adjusting direction of laser light for diffraction grating fringe exposure device
Inventor: YASUDA KENJI
IPC: G02B5/18
Filed: 1988-08-27
Abstract: PURPOSE:To expose diffraction grating stripes with high accuracy by detecting the deviation of laser light by optical sensors and displacing a direction correction optical system automatically according to the deviation. CONSTITUTION:Photodiodes 13a and 13b in the same shape which have the same function are used as the optical sensors and they are at an equal distance from the optical axis X of the optical system, so the deviation of the laser light from the optical axis X can be known. Then the intensity of the laser light is measured by the optical sensors 13a and 13b to detect the deviation of the laser light from the optical axis from the difference between their light measured values before dividing two light flux, and the correction optical system 3 is displaced automatically according to the direction of the displacement. Consequently, light at respective corresponding points on a photosensitive material is uniformed in intensity to obtain a high-accuracy interference pattern with good diffraction efficiency.

Inventor: MATSUNO TAKASHI
IPC: G01S11/02
Filed: 1994-08-12
Abstract: PURPOSE:To simultaneously and highly precisely detect the position, the shift speed and the shift direction of a mobile object by permitting peripheral base stations to measure a transmission radio wave transmitted from the mobile object for detecting frequency shift quantity based on a Doppler effect. CONSTITUTION:When a mobile object detection processing is started, a mobile subscriber system exchange station MSL requests the search of all dead channels/slots (CH/SL) and the notice of a search result to a station 20 where the mobile object 10 being a measurement object exists and the peripheral base stations 21-26. MLS receives the notice and searches/gives the notice of common CH/SL to the stations 20-26. The station 20 transmits the non-modulated wave of a frequency fc to free CH/SL and the mobile object 10 transmits the non- modulated wave of a frequency f0 after prescribed time. The stations 20-26 detect/store received frequencies fc0-fc6 and f00-f06. The stations 20-26 calculate f00-fc0 to f061-fc6 and give the notice to MLS. MSL calculates maximum shift quantity DELTAF and DELTAFcostheta based on the notice, sets a first straight line 11 and a second straight line 12 and obtains the position and the shift speed of the mobile object.

Abstract: PURPOSE:To shorten the processing time by accommodating copying sheets due to interrupt copying in a specific bin, allowing book-binding in normal mode to resume with this stored bin position when the interrupt mode is released, and thereby accomplishing quick return to original book-binding process after completion of the interrupt processing. CONSTITUTION:When on-edge of an interrupt copying signal is sensed, a copying prohibit signal is emitted, and the bin return state is changed from normal to bin home, and the flag is given '1' during the interrupt copying mode. If the book-binding mode is not a sort mode, the current bin position is stored as return bin position, and if book-binding is completed in sort mode, '1' shall be set as the return bin position. Then the book-binding mode is retracted, and if off-edge of interrupt copying signal is sensed when non-sort mode is set, the book-binding mode in retraction shall be returned, and the bin return state be set to interrupt return. If the forward stroke book-binding is finished with the book-binding mode in sort mode and interrupt copying mode is set before commencement of backward stroke book-binding, the pin position to return after release of the interrupt mode becomes the top.

Title: Method for extracting character area of gray level image and recording medium having recorded the program thereon
Inventor: KATABUCHI NORIFUMI
IPC: G06T7/00
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To improve precision in reading and recognizing characters by extracting and specifying only a part including a character from the image of a processing object so as to execute image processing and character collation only in a partial area. SOLUTION: Based on the density value of each divided partial area, a distributed quantity is calculated to judge the area to be a character block or a background block (S201). Each partial area is rotated to calculate a distribution value from the distribution of the projecting values of each direction to judge the area to be the character block or the background block (S202). Whether the partial area is the character block or the background block is totally judged by these discriminated result to finally establish the character area (S203). Only the character area is extracted by limiting to the partial area including a character specified from the image of the processing object. Otherwise, the shape of a character boundary where variation of density is steep is extracted (S204).  Thus, character reading and recognition hardly influenced by density variation and a noise pattern existing in the background area of an original image.

Abstract: PURPOSE:To reduce a convert-processing time, by stopping the conversion by constituting a Chinese character mixed sentence by punctuation which seems to be most suitable, from a dictionary, against a ''Kana'' character-string, and executing the reconversion or proceeding to the next step by an operator's decision. CONSTITUTION:From a ''Kana'' character-string, a ''Kana'' character-string 1 which  seems to be most suitable is extracted, is converted to a part 9 of a Chinese character  mixed sentence from a dictionary, and the processing is stopped. Subsequently, since it  is different from a desired one, an operator moves the cursor to a position of 10,  instructs to execute how to punctuate and conversion once again, reconverts it to a  Chinese character mixed sentence 11, and stops the conversion. After that, since it is  different from a desired one, the operator instructs its conversion by a mark 12 once again. As a result, a Chinese character mixed sentence 13 is obtained. Since the first 3  punctuations have become desired ones, the conversion is further instructed by moving  the cursor to a mark 14, and in the end, a Chinese character mixed sentence 15 is obtained. In this way, capacity of a dictionary is reduced, the number of times of  access is decreased, and the time required for conversion is shortened.
