Title: In-furnace roll for continuous anneaing
Inventor: KUWAMOTO HIROSHI
IPC: C21D9/56
Filed: 1981-03-13
Abstract: PURPOSE:To prevent snaking of a steel strip by providing the relation of a specific equation between the surface hardness of in-furnace rolls and the surface roughness of said rolls. CONSTITUTION:The relation of the equation is provided between the surface hardness (HS; the valve at ordinary temp. indicated by Shore hardness) and surface roughness (R2: unit in micron) of an in-furnace roll. If the RZ.HS is  <=125, the snaking of a strip increases considerably, and in excess of 4,500, the  roughness of the roll is printed on the surface of the strip thus producing surface defects. It is because the movement in the transverse direction of the strip on the roll surface is restrained that the rate of snaking is lower as the roughness of the roll is higher, and it is because the surface roughness of the roll is assured at elevated temp. that the better results are obtained with the harder roll.

Title: Image recognition device
Inventor: HAYASHI TATSUO
IPC: H04N7/18
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To recognize both the contour of an object and a gap included in the contour by providing a means which acquires the gradation image of the object and a means which differentiates the data on the gradation image and calculates the position of the gap included in the contour of the object. SOLUTION: An object is photographed by a camera 8 while the projection pattern is varied by means of a light source combined with an electronic flash, etc. Thus, a space code image is obtained, and the direction set toward every point from the light source is shovm in the space code value. On the other hand, the pixel position of the space code image shows the direction of the line of sight viewed from the camera 8. Based on this direction of the line of sight and the space code value, a space code image processing part 24 calculates the three-dimensional position of the object. Then the contour of a work aggregate is acquired in a three-dimensional space. The gradation image of the object is differentiated at a differentiation processing part 30, that is, the image data are affected by a differential operator, so that a gap is decided.  This is due to a fact that a sharp bright/dark change, etc., are recognized at the boundary between works even though these works are set close to each other.

Title: Process for fabricating transparent conductive film
Inventor: TAKATOU YUTAKA
IPC: H01B1/08
Filed: 1978-03-27
Abstract: PURPOSE: To provide the subject process comprising carrying out sputtering of a metal oxide in an atmosphere in which a small quantity of a reducing gas such as H 2 , a saturated or unsaturated hydrocarbon or the like is added in an inert gas such as argon or the like, thereby to increase photo-permeability and reduce a surface resistance value.  
     CONSTITUTION: Sputtering of a metal oxide such as In 2 O 3  or the like in which SnO 2  is doped is carried out in an atmosphere in which a small quantity of a reducing gas such as H 2 , saturated or unsaturated hydrocarbon is added in an inert gas such as argon or the like, thereby to form a transparent conductive film. This transparent conductive film has a very small surface resistance RS, and the value of T/RS (T : photo-permeability) becomes large, particularly transparency at the visible light short wavelength side (about 400Å) being excellent. When the quantity of H 2  added is above 5%, the permeability decreases. Further, the influence of contaminations due to slight vacuum leakage and residual gas can be evaded, and time of vacuum drawing can be shortened and the adherence speed of the film is also high.

At the time C, the receiving switch 7 is switched to the coil 5, but restarting during the period C-D is not actuated owing to the discharge of the  capacitor 10. During the period D-F, the signal-sending switch 8 is opened, and  the capacitor 10 is completely discharged.
