Patent number: 6617012Abstract: A system and method for forming servo patterns on magnetic medium is disclosed. A magnetic film coated with a layer of styrene-acrylonitrile is stamped with a nickel stamper reproducing the negative image of the stamper pattern on the styrene-acrylonitrile. Ions are then accelerated towards the surface of the styrene-acrylonitrile, which stops the ions in the areas where the styrene-acrylonitrile is thick and allows the ions to penetrate through to the magnetic layer in the areas where the styrene-acrylonitrile is thin. The ions, which penetrate through to the magnetic layer, interact with the magnetic layer altering the magnetic layer's structure reducing its coercivity (Hc) and remnant moment (Mrt). This reproduces the stamped styrene-acrylonitrile pattern on the magnetic layer. The styrene-acrylonitrile is then removed by oxygen plasma etching the surface leaving behind a patterned magnetic medium.Type: GrantFiled: March 29, 2002Date of Patent: September 9, 2003Assignee: Seagate Technology LLCInventors: HongYing Wang, Koichi Wago, Neil Deeman, Nobuo Kurataka

Patent number: 6548124Abstract: A method for the controlled nanometer-scale deposition of molecules on a surface, by means of coherently controlled optical focusing. The coherent control is conveniently performed by inducing a linear superposition of molecular bound states, by means of electromagnetic fields supplied by an applied laser beam.

An ejection powder and a reactive ejecting gas are ejected onto a surface of a material to be treated comprising a metal product, a ceramic, or a mixture thereof. The ejection powder is heated on the surface of the material to be treated and then is reacted with the reactive ejecting gas. The resultant product is activation-adsorbed onto the surface of the material to be treated and caused to diffuse and penetrate thereinto. Thus, a layer made of a nitride or other compounds is formed.Type: ApplicationFiled: November 23, 1998Publication date: January 24, 2002Inventor: YOSHIO MIYASAKA

Patent number: 6335055Abstract: Pattern holes are completely filled with paste. As a result, occurrence of defects is prevented, and an excellent printing performance is obtained, high speed screen printing is possible, and the printing efficiency is enhanced. By sliding in the running direction above the mask plate having pattern holes, this squeegee for screen print can print the paste supplied on the mask plate to the substrate through the mask plate. It includes a contacting portion for contacting with the surface of the mask plate, a filling portion disposed at the running direction side of the contacting portion, and an agitating portion disposed at the running direction side of the filling portion. The agitating portion has a function of rotating the paste by sliding. The filling portion has a function of filling the pattern holes with the paste along with the sliding motion. The paste applied in the pattern holes can be printed on the substrate.Type: GrantFiled: March 16, 2000Date of Patent: January 1, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Seiichi Miyahara, Takaaki Sakaue, Kimiyuki Yamasaki, Michinori Tomomatsu, Seikou Abe

Patent number: 6329018Abstract: An applicator is used at first to apply to a paper sheet an ink that is composed of two or more pigments and/or dyestuffs of different adhesional forces to the paper sheet, so as form an ink layer on the sheet along a desire pattern. Next, an erasing rubber is used to scrub the ink layer along a desire locus, in a freehand manner. Alternatively, the scrubbing may be done through a template overlaid on the ink layer. As a result, the pigments or dyestuffs weakly adhering to the paper will be removed from it, with the other pigments or dyestuffs remaining on the sheet, thus forming a desired linear figure in accordance with the desired locus, such that an epoch-making ornamental and visual effect is afforded in the drawn linear figures by this novel method.Type: GrantFiled: April 10, 2000Date of Patent: December 11, 2001Assignee: Sakura Color Products Corp.Inventor: Toshinao Yuasa

Patent number: 6306562Abstract: An ink jet print head suitable for high-density printing. The ink jet print head comprises a plurality of nozzles for ejecting an ink, ink chambers, for passage and pressurization of the ink, communicating with the nozzles, and pressurizing means for creating a change in volume of the ink in the ink chamber to eject the ink through the nozzles. The ink chamber comprises a base plate member comprised of a transparent substrate having a predetermined form and dimension, a base wall member made of a material impermeable to light, the base wall member being provided above the base plate member in a pattern form according to the form of the ink chamber, and a partitioning member provided, above the base plate member, in areas not occupied by the base wall member. The partitioning member is formed from a partitioning member-forming, photosensitive material by photolithography using the base wall member pattern as a mask. A process of producing the above ink jet head is also disclosed.Type: GrantFiled: February 10, 2000Date of Patent: October 23, 2001Assignee: Citizen Watch Co., Ltd.Inventors: Tomoo Ikeda, Etsuo Yamamoto, Yoshimasa Shirai

Patent number: 6299940Abstract: A glass ceramic article is decorated with ceramic paints in a screen printing process in accordance with which two, mutually corresponding grate-shaped structural elements are arranged on the surface of the glass ceramic article to form a closed, full-surface decorative coating so that the surface beneath it is not visible. The first structural element consists of ceramic paint members covering respective separate parts of the surface with intermediate spaces between them, while the second grate-shaped structural element consists of other ceramic paint members covering the intermediate spaces between the ceramic paint members of the first structural element but only at most overlapping edges of the ceramic paint members of the first structural element without covering them. The closed full-surface decorative coating can have a two-color pattern, such as a black and white pattern.Type: GrantFiled: July 2, 1998Date of Patent: October 9, 2001Assignee: Schott GlasInventors: Susanne Rapp, Holger Sieck
