  • Publication number: 20240131827
    Abstract: An impact-resistant polypropylene film and a method for producing the same are provided. The impact-resistant polypropylene film includes two outer layers and a middle layer. Each of the outer layers includes a propylene block polymer. The propylene block polymer includes a propylene monomer and an ethylene-propylene polymer, and the ethylene-propylene polymer is dispersed in the propylene monomer to form a sea-island structure. The sea-island structure includes a sea phase and an island phase, the propylene monomer is defined as the sea phase, and the ethylene-propylene polymer is defined as the island phase. The middle layer includes a propylene block polymer and an ethylene elastomer. Based on 100 parts by weight of the middle layer, a content of the propylene block polymer is 60 to 80 parts by weight, and a content of the ethylene elastomer is 20 to 40 parts by weight.

  • Patent number: 8890157
    Abstract: The present invention provides a pixel structure including a substrate, a thin-film transistor disposed on the substrate, a first insulating layer covering the thin-film transistor and the substrate, a common electrode, a connecting electrode, a second insulating layer, and a pixel electrode. The thin-film transistor includes a drain electrode. The first insulating layer has a first opening exposing the drain electrode. The common electrode and the connecting electrode are disposed on the first insulating layer. The connecting electrode extends into the first opening to be electrically connected to the drain electrode. The connecting electrode is electrically insulated from the common electrode. The second insulating layer covers the first insulating layer, the common electrode, the connecting electrode, and has a second opening exposing the connecting electrode. The pixel electrode is disposed on the second insulating layer and electrically connected to the connecting electrode through the second opening.

  • Patent number: 7105909
    Abstract: A structural configuration and manufacture method is applied to manufacture electronic circuits on a ceramic substrate including capacitor and inductors for filters. The electronic circuits have strong bonding to securely adhere to the SOG-coated substrate when the SOG is cured at an elevated temperature supplemented with high nitrogen flow during the curing process. The SOG coated ceramic substrate shows excellent layer compatibilities during temperature variations because reduced differences of thermal coefficients between different layers.

  • Patent number: 6387231
    Abstract: A susceptor device in a masked sputtering chamber is disclosed. The device of the present invention comprises a susceptor, a lifter and at least one heater. The susceptor, having at least one trench, is coupled with the lifter having at least one rod. The heater is disposed in the trench and coupled with the rod through the access hole at the bottom of the trench. After the sputtering process for forming indium tin oxide (ITO) film is completed, a baking process is applied to the mask in the chamber for converting the amorphous ITO film formed on the mask to polycrystalline ITO film, thereby increasing the life of the mask.
