  • Publication number: 20050121819
    Abstract: A laminate oleophilic reformative clay and a method of production for the same are described, and a material and method of production for ABS nano-metric composite material produced by the same are also described. The ABS nano-metric composite material is waterproof for a self-cleaning ability and has enhanced strength. The cost to produce the ABS nano-metric composite material is also reasonable. The ABS nano-metric composite material is made of ABS substrate formed from ABS material and laminate oleophilic reformative clay uniformly distributed in the ABS substrate.

  • Patent number: 6887074
    Abstract: A continuous production vacuum sintering apparatus has a conveyer unit and a plurality of vacuum sintering systems individually transferred by the conveyer unit. Each of the vacuum sintering systems includes a sintering furnace, a vacuum control unit communicating with the sintering furnace via an exhaustion valve, a temperature control unit electrically connecting the sintering furnace, and a partition disposed in the sintering furnace and adjacent to the exhaustion valve. The vacuum sintering systems correspond to respective sintering steps, each of which continues from a previous one with a predetermined period. The vacuum sintering systems are separate from one another. The respective pressure and temperature conditions provided by the corresponding vacuum sintering systems do not interfere with one another.

  • Publication number: 20050088072
    Abstract: A self-adhesive frame is applied in package of field emission display, the manufacturing method for the same and the package method by the same being also discussed in the specification. The self-adhesive frame can be designed as an independent component and suitable to be manufactured independently. The cathode plate and the anode plate do not need to join the process of pre-heating of the self-adhesive frame. The self adhesive frame also has a plurality of fixing side strips for alignment of temporary fixing of the cathode plate and the anode plate. Wherein the fixing side strips do not increase the void area of the field emission display. The self-adhesive frame comprises: a main body frame having the cathode plate sealing surface and the anode plate sealing surface; and a fixing side strip extending from the outer side of the main body frame.
