  • Patent number: 8541250
    Abstract: A method for continuously manufacturing a liquid crystal display device by bonding a polarizing film to a liquid crystal panel with a pressure-sensitive adhesive interposed therebetween, includes a polarizing film supply step including drawing an optical film laminate from the continuous roll placed in a dry environment, cutting at least a polarizing film and a pressure-sensitive adhesive, while leaving a carrier film uncut and feeding the sheet piece and the pressure-sensitive adhesive piece; a liquid crystal panel supply step including feeding the liquid crystal panel in a first humid environment having a relative humidity higher than that of the dry environment; and a bonding step including bonding the sheet piece to the liquid crystal panel with the pressure-sensitive adhesive piece interposed therebetween in a second humid environment having a relative humidity higher than that of the dry environment.

  • Patent number: 8398806
    Abstract: The invention is to provide a method for manufacturing a joined sheet product. The method comprising a first joining step including opposing a transverse end face of a first sheet product(1) to a transverse end face of a second sheet product(2) and joining release films of the first and second sheet products with a first joining member(30); a removing step including removing a portion of an intended member including at least a surface protecting member so as to leave at least the release film and a pressure-sensitive adhesive provided on the release film among the constituent members of both or any one of the first and second sheet products(1, 2), wherein the portion has a predetermined length from the transverse end face of the intended member; and a second joining step including providing a second joining member(40) on at least an exposed portion(40b) resulting from the removal of the intended member to join the surface protecting member sides of the first and second sheet products(1, 2).

  • Patent number: 8252136
    Abstract: The invention is to provide a process for production of a connected sheet product, which makes it possible to connect opposed end faces of two or more sheet products. A process for production of a connected sheet product including sheet products that are connected to one another and each have at least an optical member and a release film provided on one side of the optical member with a pressure-sensitive adhesive interposed therebetween, comprising: opposing a transverse end face of a first sheet product to a transverse end face of a second sheet product; connecting release films of the first and second sheet products with a connecting member (30a); and connecting surface members of the first and second sheet products with a connecting member (30b) on the opposite side from the release films.

  • Patent number: 6496276
    Abstract: There is provided a printer, in which print data from an external electronic appliance is transmitted to a computer and processed therein, and the processed data is supplied to a printing unit, and then a picture based on that processed print data can be printed by means of the printing unit. This printer includes a parallel I/O terminal (or serial I/O terminal) to which a computer is connected, a built-in infrared ray transmitter/receiver to which the external electronic appliance having an infrared ray transmitter/receiver is connected through the infrared ray transmitter/receiver, a first transmitting path for connecting the parallel I/O terminal (or serial I/O terminal) and the built-in infrared ray transmitter/receiver, and a second transmitting path for connecting the parallel I/O terminal (or serial I/O terminal) and the printing unit.

  • Patent number: 5930401
    Abstract: A detecting unit generates defference data between optical black level of digital input data and a predetermined black level and generates .gamma. characteristics selection signal. An offset signal obtained from the difference is added to the input data by an adding circuit. A .gamma. characteristics setting unit is supplied with the difference data and the output signal of the adding circuit and outputs a signal in which a white level, black level and .gamma. characteristics are corrected.
