    Abstract: A glass layer 3 is irradiated with laser light L2 for temporary firing in order to gasify a binder and melt the glass layer 3, thereby fixing the glass layer 3 to a glass member 4. Here, an irradiation region of the laser light L2 has regions A1, A2 arranged along an extending direction of a region to be fused R and is moved along the region to be fused R such that the region A1 precedes the region A2. The region A2 irradiates the glass layer 3 before the glass layer 3 molten by irradiation with the region A1 solidifies. This makes the glass layer 3 take a longer time to solidify, whereby the binder gasified by irradiation with the region A1 of the laser light L2 is more likely to escape from the glass layer 3.

  • Patent number: 8742287
    Abstract: Certain example embodiments of this invention relate to apparatuses for sealing the tips of pump-out tubes of vacuum insulating glass (VIG) units, and/or associated methods. In certain example embodiments, a laser source used in sealing the pump-out tube is thermally insulated from the VIG unit and emits a laser beam through one or more windows in an oven towards a mirror located therein. The mirror is located so as to redirect the laser beam onto the pump-out tube to thereby seal it. For instance, a substantially horizontal laser beam emitted from a laser source located outside the oven enters into the oven through one or more windows and is reflected by a mirror towards the pump-out tube to be sealed. The repositioning of the laser source advantageously can change its effective focal length and/or the location of the laser beam, e.g., because of the fixed location of the mirror.

  • Patent number: 8429935
    Abstract: It arranges a bonding material between a pair of base materials having different heat capacities and in which a difference between thermal expansion coefficients thereof is within 10×10?7/° C.; and bonds the pair of the base materials by the bonding material, by irradiating electromagnetic wave to the bonding material to melt and then harden it, wherein a thermal expansion coefficient at part of the bonding material facing one of the pair of the base materials of which the heat capacity is smaller is smaller than a thermal expansion coefficient at part of the bonding material facing the other of the pair of the base materials of which the heat capacity is larger by a difference within 10×10?7/° C., thereby bonding the base materials of which a difference of thermal expansion coefficients is relatively small, as preventing breakage and crack from occurring and further suppressing a degree of warp.

  • Patent number: 8424746
    Abstract: To easily bond substrates even made of materials whose linear expansion coefficients are different from each other when manufacturing an optical component used by transmitting light through an inside thereof. Buffer layers made of an amorphous inorganic substance causing a brittle fracture are formed on bonding surfaces of a plurality of substrates having linear expansion coefficients different from one another, and the substrates to be bonded are stacked so that the buffer layers are faced to each other. Then, a heat treatment is performed for a stack, and thereby direct bonding via an atom is formed between the buffer layers.

  • Publication number: 20130029039
    Abstract: Manufacturing method of grinding surface on glass cosmetics, in particular the nail and skin file, from flat glass of FLOAT type, is carried out by marking at least one abrasive surface on one or two sides of a glass pane or intermediate product. This surface is then coated with fusing glue, powdered with clean quartz sand with grain size between 1 and 500 ?m using a sieve, and the surplus sand is knocked-down. The intermediate product with fixed sand is inserted into the fusing furnace where it is baked at the temperature of up to 900° C. The abrasive surface may be roughened by sand blasting before the fusing glue application; the intermediate product coated with fusing glue can be decorated with glass fritte.

  • Publication number: 20130011598
    Abstract: When local heating by use of laser sealing or the like is applied, the bonding strength between glass substrates and a sealing layer is improved to provide an electronic device having increased reliability. An electronic device includes a first glass substrate, a second glass substrate, and a sealing layer to seal an electronic element portion disposed between these glass substrates. The sealing layer is a layer obtained by locally heating a sealing material by an electromagnetic wave, such as laser light or infrared light, to melt-bond the sealing material, the sealing material containing sealing glass, a low-expansion filler and an electromagnetic wave absorber. In the first and second glass substrates, each reacted layer is produced to have a maximum depth of at least 30 nm from an interface with the sealing layer.

  • Publication number: 20130004779
    Abstract: A method for manufacturing a light-emitting-element mounting substrate includes a step of applying a glass paste using powder of a glass material having a softening point higher than a softening point of a glass component contained in a glass-ceramic green sheet and lower than a melting point of silver so as to cover a conductor paste which is applied to a main surface of the glass-ceramic green sheet and consists of or consists primarily of silver; and a step of coating a metal layer obtained by heating them and sintering the conductor paste, with a transparent glass layer obtained by melting and then cooling the glass paste. By using the glass paste, the reaction of silver in the conductor paste with the glass component in the glass paste upon heating is suppressed, and the metal layer can be coated with the glass layer having high transparency.

  • Patent number: 8307674
    Abstract: Hot-melt sealing glass compositions that include one or more glass frits dispersed in a polymeric binder system. The polymeric binder system is a solid at room temperature, but melts at a temperature of from about 35° C. to about 90° C., thereby forming a flowable liquid dispersion that can be applied to a substrate (e.g., a cap wafer and/or a device wafer of a MEMS device) by screen printing. Hot-melt sealing glass compositions according to the invention rapidly re-solidify and adhere to the substrate after being deposited by screen printing. Thus, they do not tend to spread out as much as conventional solvent-based glass frit bonding pastes after screen printing. And, because hot-melt sealing glass compositions according to the invention are not solvent-based systems, they do not need to be force dried after deposition.
