Title: Character feature extracting system
Inventor: TANAKA AKIMICHI
IPC: G06K9/46
Filed: 1990-08-13
Abstract: PURPOSE:To accurately extract character feature amounts even from a character image whose size is extremely different from a standard size by searching a directional contribution degree towards a detected outer hull point, moreover obtaining an average in a section, and outputting the value as the feature amount of an inputted character image. CONSTITUTION:The inputted character image is moved in parallel so that a center of gravity is a center by a position normalizing means 101. The secondary moment of the surroundings of the center of gravity is calculated by an expansion/reduction ratio deciding means 102, and this is compared with a preliminarily applied secondary moment standard value so that an expansion ratio or reduction ratio mu is decided. An outer hull point detecting means 103 scans the inputted character image across a whole to the same direction, and detects the outer hull point of a character line. A directional contribution degree calculating means 104 with a line width correction obtains the directional contribution degree of the detected outer hull point. An in-section averaging means 105 with an expansion/reduction correction corrects the expansion or reduction ratio mu. Then, the average of the contribution degree is calculated and outputted as the character feature amounts.

Title: Method for forming position detecting mark
Inventor: KUZUHARA TORU
IPC: H01L21/205
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To form a position detecting mark by using a semiconductor crystal layer which is selectively grown on a pattern on an exposed semiconductor main face by using a protective layer having an opening as a mask. SOLUTION: A protective film 7 is deposited on a substrate 1 by a chemical vapor deposition method, and further, a photoresist film 8 is deposited. An opening 9 is formed by using a position detecting mark 5 and the protective film 7 is etched by using the photoresist film 8 as a mask. The photoresist film 8 is removed and an opening 10 is formed. A first crystal layer is selectively grown on the substrate 1 covered with the protective film 7 having the opening 10. In the opening 10 part, a first crystal layer 11 is grown. On the protective layer 7, a polycrystal film 12 is grown. On the position detecting mark 5, a crystal 51 having the same shape as that of the base is selectively grown. Consequently, the selectively grown crystal layer and the position detecting mark having the same height as that of the crystal layer are simultaneously selectively grown.

Filed: 1990-08-14
Abstract: PURPOSE:To reduce the length of a bonding wire independently of the quantity of a package left unworked by devising a vertical projection of a side to which a lead of a semiconductor element is stretched onto the package to be at the outside of a bottom of a mount seat. CONSTITUTION:A projection seat 16 is formed to mount a microwave semiconductor element 1 in the middle of a package 14. The size of an upper face of the projection seat 16 in the lengthwise direction is set so that the width W is 530+ or -20mum and the length U is 530+ or -20mum in the lengthwise longer slightly than the size L of the microwave semiconductor element 1 in the lengthwise direction. The electrode face of the microwave semiconductor element 1 and that of a matching circuit 2 are made the sane level by mounting the microwave semiconductor element 1 onto the projection seat 16. Moreover, the interval lbetween the end of the microwave semiconductor element 1 and the end of the matching circuit 2 is reduced to an extent of nearly 20mum (error in the processing). Since the length of the bonding wire is reduced to the utmost, the inductive component of the bonding wire is reduced and the restriction in the design of the matching circuit is considerably relaxed.

Title: Flying head type thermal printer
Inventor: KUMAZAWA YUKIYOSHI
IPC: B41J2/345
Filed: 1986-09-11
Abstract: PURPOSE:To realize a high-speed printing with a small drive current, by a method wherein a plurality of groups of heating elements are disposed offset by a fixed distance in the traveling direction of a head and the heating elements are driven by the group offset by a fixed time. CONSTITUTION:Respective heating elements of a first heating element group 8a and second heating element group 8b are longitudinally arranged at one dot pitch D, and the first and second heating element groups 8a, 8b are spaced (1+1/2) dot pitch from each other in the travel direction of a head 8 to the first and second heating element groups 8a, 8b. In this condition, in driving, the first and second heating element groups 8a, 8b are alternately driven for recording in the sequence of 8a   8b   8a   8b... while the thermal head 8 is run at a approximately constant speed. Therefore, the respective heating element groups 8a, 8b are driven without overlapping on each other, which enables a recording with a small drive current. Thus, with a drive current nearly similar to that as usual, the number of the heating elements of the head can be increased to enable a simultaneous printing of two or more lines to obtain high-speed printing.

Title: Cathode-ray tube and manufacture of electron gun
Inventor: KOIZUMI YUKIO
IPC: H01J29/50
Filed: 1991-08-27
Abstract: PURPOSE:To enhance focus characteristics and to prevent generation of grid emissions by making the aperture of a G1 electrode smaller than that of a G2 electrode, the G1 and G2 electrodes forming a control electrode and an accelerating electrode, respectively. CONSTITUTION:The aperture of a G1 electrode 21 which serves as a control electrode is larger than that of a G2 electrode 22 which serves as an accelerating electrode. Focus characteristics on a fluorescent screen are such that a crossover aperture focused by a prefocus lens system comprising a cathode 20 and the G1-G3 electrodes 21-23 is focused on the fluorescent screen by a main lens system. Therefore the larger the main lens aperture and the smaller the crossover aperture, the better the focus characteristics, and the crossover aperture is almost proportional to the aperture of the electrode 22 and the focus characteristics are enhanced by reducing the crossover aperture. By making the aperture of the electrode 22 smaller than that of the electrode 21 penetration of the electric potential of the electrode 23 into the hole of the electrode 21 is restrained so that generation of grid emissions is restrained.
