Title: Method for formation of pattern
Inventor: MARUYAMA YOUJI
IPC: H01L21/302
Filed: 1983-06-01
Abstract: PURPOSE:To enable to efficiently form a microscopic pattern by a method wherein an etching is preferentially performed on the layer film to be processed which is exposed by performing a uniform etching on high molecular resin. CONSTITUTION:An organic pattern 2 is formed on the surface of an Si substrate 1. Besides, an Au film 3 is formed thereon as a layer to be processed. Then, an organic film resist 4 is applied on the layer 3 to be processed, the openings in the film 3 are filled up with the resist 4, and a flat surface is formed. An ion milling is performed until the Au film is removed. As the ion milling speed of the resist 4 is one third of that of Au, the Au film can be removed preferentially. The resist 4 and the pattern 2 remained in the final stage are removed using oxygen plasma. As the Au film is not changed by oxygen plasma, it is left on the Si substrate as a pattern 6.

Title: Production of tin electroplated steel sheet
IPC: C25D5/48
Filed: 1992-03-23
Abstract: PURPOSE:To produce the tin electroplated steel sheet by treating a cold rolled steel sheet in an integrated line of continuously subjecting the steel sheet to degreasing, continuous annealing, pickling and tin electroplating, then to temper rolling and chromate treating. CONSTITUTION:Both surfaces of the cold rolled steel sheet are electrolytically degreased and are subjected to washing and drying; in succession, the steel sheet is continuously annealed in a continuous annealing furnace of a reduced atmosphere and is then continuously passed in a pickling soln. While the steel sheet having the pickled surfaces is passed in an acidic Sn plating liquid, the steel sheet as cathode is energized and Sn is electroplated on the surfaces of the steel sheet in the amt. of 0.1 to 2.8g/m<2> per surface, and in succession thereto, the steel sheet is temper-rolled by a dry process or a wet process using fats and oils, such as dioctyl sebacate of a fatty acid ester system. Finally, the surfaces are subjected to the chromate treatment to form chromate films. A lubricant for rust prevention is applied thereon. The Sn electroplated steel sheet for DI cans having a high degree of drawability is thus efficiently produced at a low cost by the integrated operations. The generation of iron powder by the temper-rolling is prevented by continuously executing the respective process and executing the temper-rolling after the plating treatment.

Title: Electrostatic attractor
Inventor: IKEDA KAZUNORI
IPC: H01L21/68
Filed: 1994-05-10
Abstract: PURPOSE:To reduce any foreign matter production by a method wherein a specimen takes a continuity to an edge part by a method wherein the edge part is pressed against the side of the specimen using a superhard material machined to an acute angled sharp edge. CONSTITUTION:A specimen wafer 2 mounted on a dielectric material 3 having adsorbing surface flatly machined takes a continuity nonmagnetic superhard material made sharp edge 1 from the side thereof. At this time, when the space between an electrode 4 and the wafer 2 holding the dielectric material 3 is impressed with a voltage from a voltage supply 5, the dielectric material 3 may be dielectric-polarized so that the dielectric material 3 and the wafer 2 may be adsorbed by the static electricity thereof. Through these procedures, the sharp edge 1 is pressed against the side of the specimen wafer 2, thereby enabling the scattering of any foreign matter on the specimen surface to be avoided. Furthermore, due to no scratching phenomenon of the specimen 2, any foreign matter production can be reduced.

Title: Exposure head
Inventor: NISHIO TOMONOBU
IPC: B41J2/45
Filed: 1988-04-19
Abstract: PURPOSE:To control the flare of light emitted from a light source accurately and form a high-quality image free from blur by providing a barrier between light sources of an exposure head. CONSTITUTION:LED chips 74A, 74B of an exposure head 22 project an infrared beam for developing a cyan C color to a photosensitive material 16 and LED chips 76A, 76B project an infrared beam for developing a magenta M color. Furthermore, LED chips 78A, 76B project a yellow beam for developing a yellow Y color. The projected beam passes through an epoxy resin layer 88, then it is condensed by a condensing lens 61 and is focused into an image on the photosensitive material 16. This image is recorded as a latent image of dot pattern. The tri-color exposure is repeatedly performed in synchronization with the rotation of a rotary drum 20 according to image information and thus an image is recorded. Part of the beam emitted from each LED chip is reflected in the epoxy resin layer, and then is absorbed or scattered by a light shielding plate 86 without being conducted to the condensing lens 61. Consequently, the flare of light to be projected to the photosensitive material 16 is accurately controlled and therefore, an image recorded is not blurred and is of high quality.
