Abstract: A rubber resin material with high dielectric constant and a metal substrate with high dielectric constant are provided. The rubber resin material with high dielectric constant includes a rubber resin composition with high dielectric constant and inorganic fillers. The rubber resin composition with high dielectric constant includes: 40 wt % to 70 wt % of a liquid rubber, 10 wt % to 30 wt % of a polyphenylene ether resin, and 20 wt % to 40 wt % of a crosslinker. A molecular weight of the liquid rubber ranges from 800 g/mol to 6000 g/mol. A dielectric constant of the rubber resin material with high dielectric constant is higher than or equal to 2.0.

Abstract: A matte film for hot pressing and a manufacturing method thereof are provided. The manufacturing method includes steps of forming at least one polyester composition into an unstretched polyester thick film and stretching the unstretched polyester thick film in a machine direction (MD) and a transverse direction (TD). The polyester composition includes 81% to 97.9497% by weight of a polyester resin, 0.02% to 2% by weight of an antioxidative ingredient, 0.0003% to 1% by weight of a nucleating agent, 0.01% to 2% by weight of a flow aid, 0.01% to 2% by weight of a polyester modifier, 0.01% to 2% by weight of an inorganic filler, and 2% to 10% by weight of silica particles. The polyester resin has an intrinsic viscosity between 0.60 dl/g and 0.80 dl/g.

Abstract: A docking device for connecting an electronic device includes a base and a connector. The connector has a body and a connecting port on the base. The body is provided on the base to be moved between a first position and a second position. The connecting port is hidden in the base when the body is moved to the first position, and the connecting is exposed to connect the electronic device when the body is moved to the second position. The docking device may be incorporated in a portable projector.
