  • Publication number: 20080088245
    Abstract: The present invention provides a highly stable light emitting device having high light-emitting efficiency (light-extraction efficiency) with high luminance and low power consumption, and a method of manufacturing thereof. A partition wall and a heat-resistant planarizing film are formed of a same material so as to be well-adhered to each other, thereby reducing material costs. Either an anode or a cathode is formed on the heat-resistant planarizing film. The partition wall and the heat-resistant planarizing film is adhered to each other without inserting a film having different refractive index therebetween, and therefore reflection of light is not caused in an interface.

  • Patent number: 7134387
    Abstract: A refrigerant gas is collected and a compressor is removed from a discarded refrigerator, a heat-insulating housing including a heat insulator is cut/processed and separated into a plurality of pieces, and the pieces are compressed/processed by compression rollers opposing each other so as to collect a gas contained in the heat insulator. In accordance with this method, substantially no gas contained in the heat insulator is diffused at the time of cutting the heat-insulating housing, and the gas can be collected at a high concentration because it is collected by being allowed to leak out at the time of compressing. Furthermore, by using the compression rollers, closed-cells in the heat insulator can be crushed easily, thereby collecting the gas completely and reliably. Thus, it is possible to collect a foaming gas contained in the heat insulator efficiently and disassemble a refrigerator at low cost without increasing the size of equipment and an installation space.

  • Patent number: 6938318
    Abstract: A method for disassembling a discarded refrigerator that uses a foamed resin as a heat insulator according to the present invention includes the processes of cutting and separating a heat-insulating housing of a refrigerator into pieces having a predetermined size and shape; obtaining the foamed resin by passing the pieces between a pair of compression rollers arranged so as to oppose each other and compressing the pieces, thereby peeling off and separating an incompressible plate-like object layered at least on one surface of the pieces; and collecting a foaming gas by passing the foamed resin (301) between a pair of compression rollers (331, 332) arranged so as to oppose each other and compressing the foamed resin, thereby allowing the foaming gas in the foamed resin to leak out. This makes it possible to collect a foaming gas in a heat insulator while maintaining a high concentration with small equipment at low cost.

  • Publication number: 20050067953
    Abstract: An object of the present invention is to realize a light emitting device having low power consumption and high stability, in addition to improve extraction efficiency of light generated in a light emitting element. At least an interlayer insulating film (including a planarizing film), an anode, and a bank covering an edge portion of the anode contain-chemically and physically stable silicon oxide, or are made of a material containing silicon oxide as its main component in order to accomplish a light emitting device having high stability. Generation of heat in a light emitting panel can be suppressed in addition to increase in efficiency (luminance/current) of a light emitting panel according to the structure of the present invention. Consequently, synergistic effect on reliability of a light emitting device is obtained.
