Title: Circuit for determining segment displayed and operated by computer system
Inventor: KURISU MARAKOFUSUKII
IPC: G06T15/80
Filed: 1989-11-07
Abstract: PURPOSE: To speed up graphic display by processing only the information on the four vertexes of a quadrilateral in accordance with the definition of a graphic shape that the graphic shape is considered to be composed of plural lower parts which are respectively the quadrilaterals. CONSTITUTION: The change in the X and Y values between the vertexes of first and second segments is defined and whether the inclination of the first and second segments is larger than 1 or not is decided. The value of the error of the first and second segments is then so set as to be equaled to the larger of the change in the X and Y between the vertexes. The value of the X term or Y term indicating the max. change between the vertexes is subjected to increment starting from the initial position of the first and second segments. The min. change of the X term or Y term is successively decreased from the error of the first and second segments while the X term or Y term is subjected to the increment every time until the error is made zero.  The X term or Y term indicating the min. change between the vertexes of the first and second segments is subjected to the increment as the error turns to zero. The operation is continued until the X value and the Y value are equaled to the X value and Y value of the final vertexes of the segments. As a result, the graphic display is speeded up.

Abstract: PURPOSE:To enhance the upper limit of monitor substrate quantity to a large extent, by enabling the highly accurate control of a film thickness in the vapor deposition of a substance with a low refractive index by taking up a polyimide film substrate to be used in a roll form from the outside. CONSTITUTION:A thickness monitor film 1 is mounted to a roll shaped film supply device 2 and connected to a film take-up device 3 through film tensioning auxiliary rolls 4. The device 3 sends an arbitrary amount of the film 1 by a take-up shaft 6 on the basis of the operation from the outside of this apparatus. The whole is covered with a deposition preventing cover 19 having an opening part at the optical measuring part thereof and a part of the film is exposed to the position of said opening part through which a light path 18 passes. This exposed part is heated by a heater 5 determining the vapor deposition condition of the film 1. Because a polyimide film is used as the film 1, said film has a refractive index of 1.78 in a visible region and, in the vapor deposition of a substance with a low refractive index like fluoride, highly accurate control of a film thickness can be performed. The film 1 is taken up little by little to draw out a new film surface and vapor deposition can be alternately performed.
