  • Patent number: 7006344
    Abstract: The present invention provides a bis(4-mercaptophenyl) sulfide derivative represented by general formula 1. This derivative is a monomer that can form a dielectric film suitable for an electronic component. The present invention further provides a method for producing this derivative and an electronic component having high characteristics under excellent humidity and high temperature.

  • Publication number: 20050129860
    Abstract: A liquid resin material stored in a resin material cup is sent to a supply tank under pressure through a primary side supply pipe by increasing the pressure in a pressure tank. The supply tank is provided with a piston that is displaced in accordance with the amount of the resin material in the supply tank, and the resin material is quantified by the stroke of the piston. The quantified resin material is sent to a heating member through an evaporation side supply pipe, is evaporated by heating, and condenses on a substrate. The resin material is quantified by filling the supply tank with the resin material temporarily, and only the filling resin material is sent to the heating member. Therefore, an evaporation amount becomes constant, and as a result, the thickness of a resin thin film is stabilized.

  • Patent number: 5331504
    Abstract: A film capacitor having moisture resistance includes a capacitor element having (a) a multilayer structure made of stacked dielectric films or a wound dielectric film, each dielectric film having a metallic layer formed on its surface, and (b) a pair of outer electrodes electrically connected to the metallic layer, and a coating layer covering the capacitor element. The coating layer is made from at least one polysiloxane, at least one organometallic compound or a combination of the polysiloxane and the organometallic compound, wherein the organometallic compound is selected from the group consisting of organoaluminum compounds, organosilicon,compounds, organotin compounds and organotitanium compounds.

  • Patent number: 4959748
    Abstract: A film capacitor having metallic layer electrodes, organic dielectric films interposed between the metallic layer electrodes, and a pair of end surface electrodes disposed at the opposite ends of the capacitor and alternately connected to the metallic layer electrodes. The end surfaces of the dielectric films adjacent to each other and located at the opposite end surfaces of the capacitor are formed with irregularities.
