  • Publication number: 20100117525
    Abstract: An organic EL panel comprises an element forming substrate, an organic EL element, which is formed on the element forming substrate, an adhesive layer, which is formed at a periphery of the element forming substrate so as to surround the organic EL element, and a sealing substrate, which is bonded to the element forming substrate through the adhesive layer. A hermetically sealing section, which is provided with low melting point metal layers, is formed at a position adjacent to the adhesive layer.

  • Publication number: 20100109516
    Abstract: In a method for manufacturing an electronic device, a low melting point metal layer is provided to seal an electronic element between a pair of resin substrates each having a barrier layer laminated thereon. The low melting point metal layer bonds the barrier layers of the resin substrates to each other. The method includes the steps of: providing a light absorbing layer between at least one of the barrier layers and the low melting point metal layer; and irradiating a laser beam having a wavelength within a range from 350 nm to 600 nm onto the light absorbing layer through at least one of the resin substrates and the barrier layer laminated thereon, to heat and fuse the low melting point metal layer, thereby bonding the barrier layers to each other.

  • Patent number: 6121621
    Abstract: An ultraviolet detector comprises a metal tubular member which hermetically encloses an anode and a cathode therein and is filled with a discharged gas introduced therein from a metal exhaust tube. After the anode and the cathode are enclosed within the tubular member, the ultraviolet detector can be made without being subjected to any glass fusing process. Accordingly, the inside of the sealed vessel V1 can be prevented from being contaminated with fluorine, whereby the ultraviolet detector with stable characteristics can be provided.

  • Patent number: 5959301
    Abstract: The ultraviolet detector in accordance with the present invention comprises a sealed vessel enclosing a discharged gas therein, and a metal anode and a metal cathode which are disposed close to each other within the sealed vessel so as to generate therebetween discharge in response to ultraviolet radiation entering the sealed vessel. The anode and cathode are independently secured to the sealed vessel with a plurality (at least three pieces each) of anode pins and cathode pins, respectively. An electrically-insulating spacer is disposed between the anode and cathode so as to fix their relative positions with respect to each other, thereby defining a discharging gap, by which discharge is stably generated between these electrodes. The current resulting from the discharge is observed so as to detect the incidence of ultraviolet radiation.
