Title: Electronic filing device provided with image data copying function
Inventor: NAKAMURA YUTAKA
IPC: G06T11/80
Filed: 1990-02-07
Abstract: PURPOSE:To obtain the electronic filing device which can simplify a document generating operation, and also, can obtain an attractive copy image by executing a copy of an original image, etc., to an optimal position detected by a centering means at the time of executing a copy of an original image, etc. CONSTITUTION:First of all, a reference position, start point coordinates xs, ys and an end point (diagonal point) coordinate of an original image are designated. As a result, a horizontal direction size DELTAxs and a vertical direction size DELTAys are calculated. Subsequently, with regard to an area in which it is desired to copy the original image, start point coordinates (x), (y) and its end point coordinate are designated. As a result, a size DELTAx and DELTAy are calculated. In a real size copy, DELTAxs<=DELTAx, therefore, the start point coordinates (x), (y) of a set copy destination area are changed to x' and y'. Therefore, the center position of the size DELTAx is derived, and the start point coordinate of the copy destination area is moved so that its position coincides with the center of an original image area. In the vertical direction, as well, the foregoing is executed in the same way. As a result, the coordinates (x), (y) are changed to the coordinates x1, y1. In the case of a copy accompanied with a variable power processing, the original image variable power processing is only executed in a state that the center positions in both areas coincide with each other, and its processing is executed extremely simply.

IPC: G03F7/26
Filed: 1987-02-09
Abstract: PURPOSE:To produce a wafer free of shortage of patterning due to the peeling off of resist patterns or deterioration in sensitivity of resist and defects due to foreign matters, by spraying high-pressure gas containing vapor of primer to the wafer. CONSTITUTION:A primer treating apparatus is constructed such that a gas such as N2 whose pressure is reduced by a pressure-reducing valve is introduced into a pressure vessel 1 containing a primer agent 5 and the primer agent is sprayed to a wafer 4 by means of an air gun 2 including a filter. For example, the primer agent may be HMDS (hexamethl disilazane) and the wafer may be a borosilicate glass wafer. The high pressure of the N2 gas is reduced for example to about 4 kg/cm<2> by the pressure-reducing valve before the gas is introduced to the pressure vessel. The pressure vessel has a volumetric capacity of 2l, for example, and it receives 100 cc of HMDS. However, the inside space of the vessel is filled with vapor of HMDS rich in volatility. Accordingly, it is possible to obtain a desirable result when the content of the vessel is sprayed to a glass wafer of about 200 mmphi by means of the air gun, and favorable result was obtained in experiment.

Title: Image coder and image coding method
Inventor: KODAMA TOMOYA
IPC: H04N19/176
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To conduct coding by which a picture with less out-of focus of edges and ringing can be reproduced through coarse quantization even in the case of coding at a low bit rate. SOLUTION: A threshold decision section 6 evaluates the spatial frequency of DCT coefficients obtained by a DCT section 1 and decides a threshold for each DCT coefficient so that the threshold is increased for a DCT coefficient with a higher spatial frequency. A DCT coefficient conversion section 2 evaluates the absolute value of each DCT coefficient, stores the values of the coefficients whose absolute values are large and decreases the value of the coefficients with smaller absolute values further through continuous and nonlinear transformation. This transformation is conducted stronger for DCT coefficients of higher orders and weaker for DCT coefficients of lower orders by using the threshold getting larger as the order becomes higher.

Title: Magnetization correction method of earth magnetism azimuth sensor
Inventor: SHIMIZU OSAMU
IPC: G01C17/28
Filed: 1987-02-10
Abstract: PURPOSE:To correct the magnetization of a sensor without altering circular running and a running direction, by mounting two earth magnetism azimuth sensors at a predetermined positions and calculating an angle of deflection and quantity of deflection caused by magnetization on the basis of the output signals from the sensors. CONSTITUTION:For example, flux gate type earth magnetism azimuth sensors 2, 3 are mounted on a vehicle 1 in the vicinity of the roof 11 thereof. Therefore, the sensors 2, 3 receive only the effect of the magnetic field due to the equivalent magnet 12 of the roof 11 (the flux densities G1, G2 received by the sensors 2, 3) and that of earth magnetism (flux density B). Whereupon, the angle alpha of the magnetic field due to the magnet 12 crossing the sensors is calculated on the basis of the signals Vx1, Vy1, Vx2, Vy2 taken out from the output windings of the sensors 2, 3 and two real roots are obtained from the quadratic equation relating to the quantity of magnetization G1. Next, when a running azimuth is slightly changed and two real roots are again calculated, one real root becomes equal and, therefore, said real root is set to the real quantity of magnetization G1. When correction is applied on the basis of the value G1 and the angle alpha, the real azimuth angle theta based on the center O1 of an azimuth circle can be obtained.
