  • Publication number: 20080170040
    Abstract: The touch panel of the present invention has a thermally color-changing portion in the vicinity of a connecting portion which is to be bonded by heat. It can be easily checked whether the heat press has been performed at a predetermined temperature when the wiring board is connected to the top and bottom substrates, based on the degree of coloring of the thermally color-changing portion. This allows the touch panel to be manufactured simply and to ensure reliable electrical contact and separation.

  • Patent number: 7351922
    Abstract: A touch panel uses a plurality of spacers shaped in the form of a letter L. The L-shape spacers can be manufactured by densely patterning the shapes of L in a certain specific orientation on a spacer sheet. Thus, a large number of such spacers can be made available out of a unit spacer sheet of a certain specific size, at a lowered rate of loss in the material utilization.

  • Patent number: 7351422
    Abstract: Proposed is a novel soluble trauma-healing and hemostatic cellulose fiber capable of absorbing and readily dissolving hemorrhaging trauma loci when applied thereto and of promoting the hemostatic action of blood platelets and fibrin and cell adhesion to the trauma site. The coagulation protein-containing soluble trauma-healing and hemostatic cellulose fiber is produced in that after treatment of a natural or regenerated cellulose fiber with an aqueous sodium hydroxide solution, said fiber is carboxymethylated by reaction with a monochloro acetic acid solution for a given time (hours) in such a manner that the degree of partial substitution of the glucose units constituting the cellulose molecule (etherification degree) is 0.5-less than 1.0% and that, furthermore, the coagulation proteins fibrinogen, thrombin, and coagulation factor XIII are imparted by surface application or chemical bonding.

  • Publication number: 20070273568
    Abstract: A touch panel includes a light-transmittable upper substrate, a light-transmittable upper resistor layer on a lower surface of the upper substrate, a light-transmittable lower substrate, a light-transmittable lower resistor layer on an upper surface of the lower substrate, an adhesive layer on an upper surface of the upper substrate, and a light-transmittable plate on the adhesive layer. The upper substrate is made of material having oxygen and nitrogen removed therefrom. The lower resistor layer faces the upper resistor layer by a distance. The light-transmittable plate disables oxygen and nitrogen to pass through the plate substantively. Even being used in high temperatures, this touch panel does not produce an air bubble in the adhesive layer, hence allowing a user to clearly view a display device through the touch panel.

  • Patent number: 7297887
    Abstract: A touch panel which is constituted by using an adhesive layer having a thickness which is 70% or more of a thickness of an approximately picture-frame-like spacer which allows respective outer peripheries of an upper substrate and a lower substrate to adhere to each other is provided. Due to such a constitution, when the touch panel is used under high temperature or in an environment where the temperature difference is severely large so that the thermal expansion or shrinkage is generated on upper substrate or lower substrate, these thermal expansion and shrinkage can be absorbed by the thick and soft adhesive layer. As a result, it is possible to suppress the peeling-off of upper and lower substrates thus realizing a surely manipulable touch panel.

  • Patent number: 7108515
    Abstract: A wiring substrate to be used in a variety of electronic apparatuses, and an input device, such as an optically transparent touch panel, using the same wiring substrate, and a method of manufacturing the same input device are disclosed. The invention simplifies a construction of the wiring substrate, reduces the number of manufacturing steps of the substrate, and makes all the connectors of the substrate in a single-sheet structure. The electrical and mechanical connections of those connectors to other connecting means can be thus highly reliable. Plural wiring patterns 22, 23, 24 and 25, and connectors 22A, 23A, 24A and 25A are formed on a first principal surface of wiring substrate 20. Substrate 20 includes flexible bending section P—P, and when substrate 20 is bend along bending section P—P, some connectors such as 24A, 25A are placed on a second principal surface opposite to the first one, so that wiring substrate 20 is formed.
