Title: Fingerprint collating device
Inventor: NIIZAKI TAKU
IPC: G06K9/00
Filed: 1992-01-10
Abstract: PURPOSE:To increase the processing speed for collating the fingerprints. CONSTITUTION:A fingerprint collating device collates plural collating window images which are segmented in window shapes out of the registering fingerprint image corrected through the directional filter processing based on the direction data on the rising or falling lines of the fingerprints extracted out of the prescribed areas divided from the registering fingerprint image with a collating subject fingerprint image to confirm the person in question. Then the fingerprint collating device is provided with a register memory 30 where the direction data extracted out of the registring fingerprint image are registered and a correcting means 31 which devides the collating subject fingerprint image having the same area as the registering fingerprint image into prescribed areas and carries out the directional filter processing to each corresponding area based on the direction data registered in the memory 30 to correct the bridges and cracks of the fingerprint included in the collating subject fingerprint image. In such a constitution, the collating subject fingerprint image is corrected based on the direction data extracted out of the registering fingerprint image and the fingerprints are collated with each other.

Title: Focusing detector of camera
Inventor: ISHIDA TOKUJI
IPC: G03B3/00
Filed: 1983-01-10
Abstract: PURPOSE:To detect an interval between images and perform accurate focusing detection by dividing a signal which shows the light distribution pattern of the 1st line sensor into plural blocks, and comparing each block with the light distribution pattern signal of the 2nd sensor. CONSTITUTION:A figures shows the image re-formation of front-focus, in-focus, and rear-focus images 84, 86, and 88 in line sensor area. Re-formed images 90 and 92 of the front-fucus image 84 are positioned in front of the photodetection surface 94 of the line sensor and both close to an optical axis 48. Re- formed images 96 and 98 of the in-focus image 86 are on the photodetection surface 94 of the line sensor, and re-formed images 100 and 102 of the rear- focus image 88 are behind the photodetection surface 94 and away from the optical axis. Therefore, the re-formed images 90 and 92 of the front-focus image 84 are slightly out of focus and enlarged on the photodetection surface 94. The re-formed images 100 and 102 of the rear-focus image 88 are slightly out of focus and reduced. Consequently, focusing detection is performed accurately regardless of the position of a photographic lens in relation to an object to be photographed.

Abstract: PURPOSE:To make it easy to find mistakes by a method wherein the visual display of a picture image with respect to the variation of a chip arrangement based on elimination, recovery and processing by key operation of chips indicated by a cursor is made possible, and functions to illustrate numerically the present state of a chip arrangement under treatment are provided. CONSTITUTION:Relating to an interface 12, chip arrangement information is stored on a file 13 by operating the key of an input/output device 11. This output is sent back to a display part 3 and graphic display is performed. Mistakes of arrangement, if exist, are corrected, and elimination of chips, insertion of dummy chips, etc. are executed while observing the graphic display. These data are stored on the file 13 after correction, which is stored in a memory 15 together with a file 14. When a picture drawing is started by charged particle beam equipment 19, an exposure software stored in the memory 15 is converted to a form of input to a driver 17 by an interface 16. The driver 17 converts it into voltage and electric power, and makes the equipment 19 execute a picture drawing on a wafer. The state of a wafer on which picture drawing is to be performed can be exactly determined, thereby.

Abstract: PROBLEM TO BE SOLVED: To reduce impeller clutch pressure by receiving a desired rimple signal, changing an impeller clutch pressure curve, controlling an electric hydraulic valve by receiving an impeller clutch pedal signal, and generating desired impeller clutch pressure from the impeller clutch pressure curve. SOLUTION: One of rimple preset values reducing in four stages is selected by a four-position rotary switch 205, and either of a maximum rimple of 100% or the preset value from the switch 205 is selected by a two-position locker switch 210. An electronic control 128 changes an impeller clutch pressure curve by receiving a signal by these switch positions. That is, maximum allowable pressure in a master impeller clutch pressure curve is changed to torque of a motive power transmission system, that is, to maximum allowable pressure reduced in response to desired reduction in a rimple. Therefore, torque of the motive power transmission system, that is, rimple-improved controllability can be obtained.

Abstract: PROBLEM TO BE SOLVED: To correctly correct the optical density of read-out data of images on a medium after correcting dispersions of the reflectivity of a reference white board and the transmissivity of a read-out window by correcting the optical density of the read-out data of the medium based on a specified correction coefficient calculated by a coefficient calculation means. SOLUTION: In order to read mail information, the read-out data of a reference white board are read, the light distribution characteristics of a fluorescent lamp are flattened and the optical density of the read-out data of a mail is corrected. In this image reader, a pre-processing circuit 28 calculates the ratio of an actual read-out data of the reference white board (output from a CCD 20 and amplified by an amplifier 27) and a read-out data truly equivalent to the reflectivity 1 as a correction coefficient. Then, based on the calculated correction coefficient, the optical density of the read-out data of the mail is corrected. Then, the correction value is converted to digital signals by an A/D converter 29 with a resolution of 8 bits and outputted.

The N is a fixed number such as, for example 8 or 10 times in here.  If GR>N.GL or GL>N.GR, the road surface conditions of the left and right wheels are regarded to be different from each other, the road surface is judged to be abnormal so as to inform it to a normalization part 58 and to prohibit the estimation of the tire pneumatic pressure.

Filed: 1990-01-12
Abstract: PURPOSE:To omit the need to set an unnecessary defective alternating area to an area where a read error occurred due to the abnormality of the main body of a magnetic disk device by providing an abnormal area storing means to store an area of a magnetic disk where an abnormality processing means processed the abnormality. CONSTITUTION:An abnormal area storing means 4 stores an area of a magnetic disk 7 where an abnormality processing means 2 processed the abnormality. That is, it is possible to clearly discriminate a fact that a read error is produced due to the abnormality of the means 2 from a fact that the read error is produced by the abnormality processing carried out by the means 2 owing to the abnormality of a host device. This discrimination is attained when the means 4 stores the area of the disk 7 where the means 2 processed the abnormality. Thus it is not required to set an unnecessary defective alternating area.
