Patent number: 7508478Abstract: In displaying a price label, the price can be displayed at low resolution without any problem, but a bar code requires a high resolution display. In view of this, the invention provides an electrode structure for a display apparatus that can suppress increases in cost and power consumption while preventing image quality degradation, even when a low-resolution display area and a high-resolution display area are mixed on the same display. A liquid crystal panel 10 has a main display section 11 and a sub-display section 12. In the main display section 11, pixels are arranged in a matrix pattern. In the sub display section 12, rectangle-shaped pixels are arranged in a single row, and the pixel pitch in the sub display section 12 is m/n of that in the main display section 11 (n and m are integers).Type: GrantFiled: September 17, 2004Date of Patent: March 24, 2009Assignee: Citizen Holdings Co., Ltd.Inventors: Kiyoshi Kamiya, Eiichi Tajima, Isao Ochi

Patent number: 6150018Abstract: A method for installing an electroconductive flooring and an electroconductive welding rod for use in this method are disclosed. The electroconductive welding rod is composed of a joint material including as the main component a thermoplastic resin composition of a ribbon-shape or a rod-shape, with the peripheral surface thereof being coated with an electroconductive coating material. The method for installing the electroconductive flooring is composed of the steps of laying flooring sheets in mutual contact and cutting joint-forming grooves, or laying the flooring sheets with spaces therebetween for the formation of the joints of the adjacent flooring sheets, softening the electroconductive welding rod, filling the softened electroconductive welding rod into the grooves or the spaces between the flooring sheets, and welding the adjacent flooring sheets to form joints, whereby the flooring sheets are electrically integrated.Type: GrantFiled: December 10, 1991Date of Patent: November 21, 2000Assignee: Tajioma IncorporatedInventors: Toru Iijima, Rikio Sugimoto, Eiichi Tajima

Patent number: 5604290Abstract: A self-crosslinking composition contains: (a) an oil having an unsaturated fatty acid or an ester of an unsaturated fatty acid as one of its components, (b) a drier, and (c) a polymer or an elastomer that is capable of crosslinking in the absence of a peroxide. A forming (such as a floor tile, a linoleum long floor material, a wall material and a water-proof sheet) may be manufactured by forming and curing the self crosslinking composition and then adding a filler. Since the self-crosslinking composition is capable of crosslinking without using peroxide, the crosslinking reaction is easily conducted without using special equipment to reject air. The composition has a number of advantages over crosslinking methods that use peroxide, including decreased scorch generation, decreased permanent compressive strain, and superior heat resistance and anti-aging resistance. The composition is free from pollution of sulfur and metal and generates no harmful gas during waste incineration.Type: GrantFiled: April 14, 1995Date of Patent: February 18, 1997Assignee: Tajima IncorporatedInventors: Satoru Aikawa, Eiichi Tajima

Patent number: 4844757Abstract: This process of forming ornamental joints comprises sticking a sheet flooring material onto a floor base, thereafter drawing two parallel standard lines on this stuck sheet flooring material with a desired outline and an interval corresponding to the width of the joint, sliding a cutter on the sheet flooring material along this standard line thereby to draw two parallel cuts on this flooring material, stripping the sheet flooring material between these cuts to thereby form a joint-forming grooved portion provided with a masking along side edges of stuck sheet flooring material and charging this grooved portion with a joint material. This process permits to obtain various patterned ornamental joints.Type: GrantFiled: August 27, 1984Date of Patent: July 4, 1989Assignee: Tajima Oyo Kako Kabushiki KaishaInventors: Hideyuki Nagata, Susumu Kidokoro, Masao Morota, Eiichi Tajima
