Title: Thinning processing method for finger print image
Inventor: YAHAGI HIRONORI
IPC: G06T7/00
Filed: 1989-12-08
Abstract: PURPOSE:To accurately collate a finger print by finding out the distribution of the degree of combination expressing the value of the center picture element of a mask, setting up the sum of combination degrees a the value of the center picture element of the mask, and changing all picture elements less than a certain threshold to the other value. CONSTITUTION:A mask forming plural areas like a matrix is formed, the picture elements of one value (e.g. '0') on the binary image of a finger print are set up as remarked points and successively scanned and the number of picture elements having the value '0' in the mask area of respective scanning points is counted to find out the distribution A1 to A3, B1 to B3 of the degree of combination expressing the value of the center picture element of the mask. The distribution of the degree of combination of the mask is successively scanned and the sum of the degrees of combination on respective scanning speeds in the mask area is set up as the value of the center picture element of the mask and all picture elements whose center picture element is less than a certain threshold are converted to the other value (e.g. '1'). Thereby, B3 of the value '0' in a rising line part A2 can rapidly and accurately detect and remove sweat glands to be the cause of noise for finger print collation to execute accurate collation.

Filed: 1988-12-21
Abstract: PURPOSE: To change shape of a parachute while maintaining the maximum floating force and an aerodynamic characteristic by providing an operating means capable of changing the surface shape of a parachute with a movement of the center of gravity by a user. CONSTITUTION: When a user of a parachute tilts backward, the center of gravity G is moved backward so as to pivotally move a seat 11 in the direction F2.

Title: Data receiver
Inventor: SAITO YOSHIKO
IPC: H04B1/76
Filed: 1993-11-29
Abstract: PURPOSE:To provide the data receiver for precisely estimating phase deviation between transmission and reception in a short time. CONSTITUTION:Concerning the data receiver provided with an equalizer equipped with forward side equalizing processing parts 12 and 13 and backward side equalizing processing parts 14 and 15, this device is provided with a phase deviation estimating means 16 for estimating the phase deviation between transmission and reception from the main tap coefficients of the forward side equalizing processing part 12 and the backward side equalizing processing part 14.

Title: Liquid crystal television receiver
Inventor: YAMANO MASARU
IPC: H04N5/66
Filed: 1988-12-19
Abstract: PURPOSE:To adjust a display part into the optimum angle at a viewing position even when the installed position of a liquid crystal television receiver and the viewing position are remote and to compensate for the defect of a liquid crystal element having a narrow effective visual angle by making the display part rotatable at an arbitrary angle by a remote controller. CONSTITUTION:When the tilt UP key of a remote control transmitter 4 is depressed, a drive motor 101 rotates, and a display part 2 rotates at a low speed. Further, when the pressing of the tilt UP key is released at a point where the angle of the display part 2 is made into the optimum angle, the rotation of the drive motor 101 stops, and the rotation of the display part 2 also stops according to the stopping of the rotation of the driving motor 101. On the other hand, when the rotation of the display part 2 is obstructed by external force during the rotation of the drive motor 101, while the rotation of a first flat gear 106 stops, a worm gear 104 can rotate because of the generation of slip by a slipping mechanism. Consequently, an excess load is never applied to the drive motor 101. Thus, even when the viewing position is remote from the receiver, the display part can be adjusted into the optimum angle.

Abstract: PURPOSE:To produce a permanent magnet with a high coercive force, by a method wherein a starting material employs a permanent magnet alloy consisting of a predetermined amount of gallium and the balance iron, and after the alloy is pulvierized, shaped and sintered, special aging treatments are performed. CONSTITUTION:A starting material employs a permanent magnet alloy having a composition which consists of 10-40wt.% R (but, R is at least one kinds of elements which are selected from Y and rare earth elements), 0.1-8wt.% boron, less than 13wt.% gallium, and the balance mainly consisting of iron. After the permanent magnet alloy is pulverized, shaped and sintered, a first step of aging treatment from 550-1200 deg.C to below 400 deg.C is performed, and a second step of aging treatment from 500-750 deg.C to below 400 deg.C is then repeated two times. When R is less than 10wt.%, increasing of Hc is not achieved while R is more than 40wt.%, Br is decreased, and therefore in any case, (BH)max is decreased. Now, among rare earth elements, especially, both Nd and Pr are an available element in order to obtain a high (BH)max, and therefore said R is preferred to contain at least one kinds of elements which are selected from these two elements.
