Title: Inspecting method for pattern of printed wiring board
Inventor: TSUKAZAKI KOUICHI
IPC: H05K13/08
Filed: 1979-04-25
Abstract: PURPOSE: To improve the yield of a printed wiring board by enabling an electric signal representing reflected light from a through hole to be detected as a signal of a high level just as an electric signal representing reflected light from a wiring pattern, whereby the displacement of the through hole is not actually detected, during the inspection of the wiring pattern.  
     CONSTITUTION: In order to allow the light passing through a through hole 6 to be returned upwardly, a reflector 40 is provided at the back side of a printed wiring board 1. during the inspection of the wiring board 1, the light from a light source is directed downwardly by a mirror to be applied as rays of light 31W33 to each part of a wiring board surface 2. The ray of light 31 is reflected as a ray of light 34 of a low level due to a low reflection power of an insulating material 7. The ray of light 32 is reflected as a ray of light 35 of a high level due to a high reflection power of a wiring pattern 5. The ray of light 33 passes through the through hole 6 to be reflected on the reflector 40 as a ray of light 36. The reflected rays of light 34W36 form optical images on an image sensor. The level of an electric signal from the image sensor, which represents the reflected ray of light 34 is low (I 2 ), and the levels of electric signals representing the reflected rays of light 35, 36 are high (I 3 ), (I 4 ). When these levels I 2 WI 4  are subjected to binary representation by a level I s , the levels I 3 , I 4  cannot be discriminated from each other. Accordingly, the through hole 6 is not identified so that the displacement thereof is not detected.

Title: Color recorder
Inventor: TANAKA NOBUYUKI
IPC: G03G15/01
Filed: 1990-03-05
Abstract: PURPOSE:To realize color recording of high definition without color slurring by giving tensile force to a recording paper with the aid of the difference of speed between the carrying speed of the recording paper and the traveling speed of an endless belt and giving the tensile force to the recording paper with the aid of the difference of the traveling speed between mutual endless belts. CONSTITUTION:The traveling speed of the endless belt 20C of an endless holding belt assembling body 20 is set slower than the speed of the recording paper P carried by a recording paper carrying mechanism. Due to that, when the paper P is held on the belt 20C, the tensile force is given to the paper P by the difference of the speed between the traveling speed of the belt 20C and the speed of the recording paper carried by the recording paper carrying mechanism. Besides, the traveling speed of the belt 20C of at least two endless holding belt assembling bodies 20 is made slower as it is positioned on an upstream side in the carrying direction of the recording paper. Therefore, even when the recording paper is positioned between the endless belts of at least two endless holding belt assembling bodies, the tensile force is applied to the paper P by the difference of the traveling speed between both endless belts. Thus, even when the central part of the recording paper is swollen caused by the lack of destaticization, the swollen part is flattened by the action of such tensile force and the color slurring is eliminated.
