  • Publication number: 20080026206
    Abstract: The invention presents a touch panel easy in peeling off and adhering to a display element. The touch panel of the invention forms a strong adhesive layer and a weak adhesive layer overlaid on the downside of a lower substrate. When peeling and adhering again the touch panel, it can be easily peeled off, and the weak adhesive layer does not transfer and stick to the display element.

  • Patent number: 7307231
    Abstract: A touch panel includes a first substrate, a first resistance layer on a surface of the first substrate, a second substrate, a second resistance layer on a surface of the second substrate, a spacer having substantially a frame shape provided between outer peripheries of the first and second substrates, a sheet having a surface attached to the surface of the second substrate with a first adhesive layer, and a second adhesive layer on the surface of the sheet. The second resistance layer faces the first resistance layer by a predetermined gap between the second and first resistance layers. The second adhesive layer has an adhesion property weaker than that of the first adhesive layer. This touch panel can be attached onto a display element again easily.

  • Publication number: 20070249107
    Abstract: Proving a touch panel having a superior transparent visibility, easy to manufacture and of low cost, to be used for various electronic devices. In manufacturing, forming a notch with an adhesive layer formed on an undersurface of an under substrate, under a connecting portion of the under substrate with a wiring substrate. After applying rollers for short a period of time for almost completely removing bubbles between the under substrate and the adhesive layer, adhering such under substrate to an upper substrate. Finally heating and pressing the connecting portion, connecting the wiring substrate to the substrates, obtaining the touch panel having a superior transparent visibility, easy to manufacture and of low cost.

  • Publication number: 20060170659
    Abstract: A pressure sensitive conductive sheet is provided by having a plurality of ferromagnetic conductive particles dispersed in a transparent elastic member joined together and linearly aligned with the thickness direction thereby forming a linear aggregate and then having the linear aggregate segmented into a plurality conductive elements, held linearly aligned with the thickness direction, with predetermined gaps formed therebetween. Further, a touch panel having good transparency and allowing stabilized operation is provided by interposing the pressure sensitive conductive sheet between an upper conductive layer on the lower face of an upper substrate and a lower conductive layer on the upper face of a lower substrate.

  • Patent number: 6592061
    Abstract: When material is thrown in a hopper, material of small particle diameter is loaded in between breaking teeth on two rotors and transferred toward a crushing space between the rotors by rotation. The material of small particle diameter is pressed by compression teeth on one rotor against cutting teeth on the other rotor, thereby causing compressive crushing. When material of small particle diameter clogs the crushing space and stays therein, the cutting teeth cut the material to form a gap. The breaking teeth on the two rotors move odd-shaped material or the like toward the crushing space by similar action. Consequently, the odd-shaped material assumes such a posture that it is caught between the breaking teeth, and is crushed by the breaking teeth or cut by the wedge effect.

  • Patent number: 4130389
    Abstract: A burner for a furnace comprises a first pipe for delivering fuel to the furnace and a second pipe of larger diameter than the first pipe, positioned parallel with and encompassing the first pipe, which supplies air to the furnace in the annular space between the two pipes. The second pipe includes a large diameter section and a throttle section of gradually decreasing diameter which acts to speed up the air passing therethrough. In the annular space between the large diameter section of the second pipe and the first pipe is positioned a device having guide vanes which gives the air passing therethrough a swirling motion prior to acceleration in the throttle section. The burner further includes an air swirl passage between the throttle section of the second pipe and the furnace which conveys the air into the furnace. The air swirl passage also acts to convey the fuel into the furnace since the first pipe terminates prior to entry into the furnace.
