IPC: B43L7/00
Filed: 1989-03-10
Abstract: PURPOSE:To keep directions provided with graduations becoming a marking reference constant simply by making the directions provided with graduations parallel between both vertical sides and both horizontal sides. CONSTITUTION:For example, when parallel lines in a vertical direction are drawn, a vertical scale X is placed on blank paper between both upper and lower horizontal sides 4, 5 so that both end edges X1, X2 thereof are brought into contact with the inside edges of both upper and lower horizontal sides 4, 5. The positions becoming both upper and lower ends of a line to be drawn are measured as the distances from reference points D using graduations 9 and both end edges X1, X2 of the vertical scale X is slid in a lateral direction along the inside edges of both upper and lower horizontal sides 4, 5 so that the side edges of the vertical scale X correspond to said positions and lines are drawn using the side edges of the vertical scale X. In this case, since directions provided with graduations 9 becoming a line drawing standard are mutually parallel between both upper and lower horizontal sides 4, 5 and the reference points D of the graduations 9 correspond between both upper and lower horizontal sides 4, 5, only by allowing the side edges of the vertical scale X to correspond to the positions set by measuring the distances from the reference points D, parallel line can be simply drawn using said side edges.

Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To spontaneously remove contamination without wiping off it with cloth and to provide a good image quality by providing a transparent coating layer having contamination resistance with ultraviolet radiation on a display surface of a display. SOLUTION: The display surface of a display, for preventing fat-and-oil contamination due to electrostatic adhesion, is applied with a transparent coating layer containing metal oxide photo semiconductor particles such as anatase-type TiO2 that provides contamination resistance by decomposing the contamination to carbon dioxide and water with ultraviolet radiation. For example, a transparent glass or plastic surface such as a CRT or a liquid crystal display panel is coated with a resin paint containing photo-catalytic metal oxide particles and is baked and cured to form a contamination resistant coating layer at this photocatalyst. Thickness of this coating layer is set thinner than 0.2 μm based on wavelength of light, coloring caused by interference of light in this layer can be prevented, and transparency increase with thinner coating.  In addition, a protective film with abrasion resistance or corrosion resistance can be applied for securing abrasion resistance, if necessary.

IPC: H05K1/02
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a warped board in automated assembling by forming a guide groove for cutting a discard margin in the longitudinal direction or/and lateral direction in the board so that the guide grooves do not intersect each other. SOLUTION: A V-cut part 5 as a guide groove for cutting a discard margin 3 is formed in the longitudinal direction or/and lateral direction in the board 1 for components so that the V-cut parts 5 do not intersect each other. For example, the V-cut parts 5 are arranged so that they do not intersect each other and are provided in the directions at about 90 degrees with respect to the solder flow direction. As a result, the strength of the board 1 for components can be maintained so that warping of the board 1 for components is not generated. Further, the workability when the discard margin 3 is removed is not influenced. Therefore, according to this construction, the warped board 1 for components to be generated in solder flow and solder reflow can be prevented without specially improving a solder flow apparatus.

The protective film consists of a UV-curing resin in which a material having lubricant property is dissolved or mixed, and the surface of the protective film has a fine rugged pattern. Since the UV-curing resin is used for the protective film and a material having lubricating property is mixed in the resin, enough sliding property and lubricating property are obtd., which effectively prevents mechanical damage of the surface of a medium. Since a fine rugged pattern is formed on the surface of the protective film, sucking of a floating type magnetic head can be effectively prevented.

Abstract: PURPOSE:To easily form the titled alloy into the shape and dimensions at the time of assembly, by carrying out the deformed-shape constraint and subsequent constraint removal of the titled shape-memory-treated alloy at respectively specified temps. and forming the alloy into the required shape. CONSTITUTION:A shape memory alloy (NT alloy) composed principally of intermetallic compound NiTi is melted, cast, and then subjected to hot and cold rollings so as to be formed into a tape shape. This NT-alloy bar is formed by roll forming into a U shape having a further opened end and then subjected to shape memory treatment in the above state. Subsequently, this alloy 1 is subjected to deformation constraint at a temp. where an austenitic phase starts developing or above by means of jigs 2a, 2b constraining so that two open ends of the U shape are closed. Then, after the NT alloy 1 is cooled together with the jigs 2a, 2b down to a temp. where an R or martensitic phase starts developing or below, the jigs 2a, 2b are demounted and constraint is removed. By this method, the NT alloy 1 is free from shape recovery due to spring back and maintains the constrained shape.
