Title: Optical deflector
Inventor: HIROSE YOSHIHIKO
IPC: F16B39/01
Filed: 1989-05-09
Abstract: PURPOSE:To prevent the degradation in the accuracy of the reflecting surfaces of a rotary polygon mirror by thermal expansion by fixing the polygon mirror to a seat provided to a revolving shaft by using screws having approximately the same coefft. of linear thermal expansion as the coefft. of linear thermal expansion of this polygon mirror. CONSTITUTION:M3 bind machine screws 3 are inserted into holes (b) provided on the polygon mirror 1 and the screws are screwed to M3 internal threads (c) cut to the seat 2a of the revolving shaft 2, by which the polygon mirror 1 is pinched and fixed to the revolving shaft 2. The polygon mirror 1 and the M3 bind machine screws 3 have approximately the same coefft. of linear thermal expansion. The mirror and the screws, therefore, expand by the same quantity even if the temp. of the optical deflector rises and the pressure in the part of screw heads 3a to be applied on the polygon mirror 1 does not change. The generation of the strain in the reflecting surface of the polygon mirror finished with the high accuracy is prevented in this way.

Abstract: PURPOSE:To obviate defective reproduction of gradations, by sliding an ink- scraping blade in a width direction by an actuator means according to printing information while constantly maintaining the blade in contact with a projected surface of a head roller. CONSTITUTION:When an actuator 12 is driven according to image information on a picture element basis, a blade 11 which is constantly maintained in contact with projected surfaces 1a of a transfer roller 1 is slidden in the width direction, whereby the quantity of an adhered ink 4a scraped, namely, an ink-scraping area,, in the projected surfaces 1a is varied, thereby expressing gradations. In this case, the leading edge of the blade 11 is constantly maintained in contact with the projected surfaces 1a of the transfer roller 1 and is slidden in the width direction along the projected surfaces 1a, so that the blade 11 is prevented from bounding from the projected surfaces 1a, and failure in scraping off the ink is prevented from occurring due to such bounding. Thus, defective expression of gradations can be prevented from occurring due to failure in scraping off the ink.

Title: Feature vector generation system for pattern recognition
Inventor: KATO YASUSHI
IPC: G06T7/00
Filed: 1994-05-02
Abstract: PURPOSE:To effectively absorb the variation of an input pattern and to obtain always high recognition accuracy in respect to pattern recognition having large variation in hand-written characters e.g. by dividing a pattern into plural sections based upon the spatial distribution of a 1st feature primitive reflecting the bending degree of a constitutional line. CONSTITUTION:A contour extracting function 51 extracts the contour points of an electronized pattern 9 by scanning the pattern 9 in plural directions to output a contour pattern 5a. A feature primitive extracting function 52 finds out the degree of contribution of contour points to directions based upon an input pattern 1 and the contour image 5a. A sectional primitive extracting function 53 traces the contour of the image 5a and finds out the bending degree of a local character line in each contour point. A function of converting into vector 54 divides the pattern into plural sections parallel with a scanning direction, totalizes the degrees of contribution of all contour points to directions in each section and generates a feature vector in which totalized value of the direction contribution degrees in each section is set up as each component.

Title: Diamond dresser by scattering dimples on surface and manufacture therefor
Inventor: ASANO HIROAKI
IPC: B24B53/00
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To easily apply a grinding wheel, and to maintain high accuracy over a long period by scattering dimples on the surface of a diamond dresser in a range of a specific area rate. SOLUTION: Core metal 9 being a main body of a diamond dresser is inserted into the center of a matrix, and a molten alloy 10 such as a tin alloy is poured between the core metal 9 and an elactrocasting layer 9 to form the diamond dresser integrally formed with the core metal 9. Next, a matrix 1 of graphite is removed by cutting and grinding to complete a diamond rotary dresser. Since a sticking projection adhered/fixed to the matrix wall surface is also simultaneously removed by removing the matrix, the trace is automatically formed as a dimple 12 of the dresser surface. An area rate of the dimple 12 of the diamond dresser surface is set to about 7 to 70%. Since a diamond abrasive grain is not fixed to this dimple 12, the diamond abrasive grain can be saved.

Abstract: PURPOSE:To form a semiconductor laser device, which is operated in a lateral basic mode by one crystal growth, by providing a stripe in the direction of an inverted mesa shape on a substrate and multiple-layer films having a double heterogeneous structure, which is formed by a growing method under a thermal unbalanced state. CONSTITUTION:On an n-GaAs semiconductor substrate 9, a region, which is higher than other parts, is formed in an inverted trapezoidal stripe shape in the direction of (110). Thereafter a Zn diffused layer 10 is provided. Then an n- Ga0.55Al0.45As clad layer 11, a GaAlAs active layer 12, a p-Ga0.55Al0.45As clad layer 13 and a cap layer 15 are sequentially laminated on both sides. In this constitution, a current flows only in the stripe because of the Zn diffused layer 10 held by the substrate 9 and the clad layer 11 or the substrate and the reverse conducting type formed layers. Since the growing speed of the crystal at a stepped part is slow, the active layer 12 at the stepped part is thinly grown. Light absorption by the active layer, which is not excited, does not occur. Leakage of carriers to the outside of the stripe becomes small.
