摘要:
An electronic component contained in a metal case is attached with an insulation mold at a sealing part and lead wires of the electronic component element are passing through holes on the insulator base, and the end parts of the lead wires are bent in recesses on the insulator base, thereby constituting surface mounting type electronic component.
摘要:
This invention relates to an electrolytic capacitor in which terminal is inserted in and fixed to holes of printed circuit substrate, and by providing a pin to an anode terminal or a cathode terminal which is mounted on a terminal plate in an integral forming, right insertion and fixing on the printed circuit substrate can be made.
摘要:
A device comprising a dielectric oxide film formed by anodization of a surface region of a valve metal body, a semiconductive metal oxide layer porously formed on the dielectric oxide film, and a gas permeable electrode layer formed on the semiconductive metal oxide layer with the interposal of a gas permeable carbon layer therebetween. The semiconductive metal oxide layer is formed by pyrolysis of a metal salt solution so as to be, microscopically, only partially in contact with the dielectric oxide film. After forming of the electrode layer, the device is immersed in boiling water and/or kept in a high temperature high humidity atmosphere for an adequate amount of time to stabilize the semiconductive metal oxide layer, resulting in that the semiconductive metal oxide layer has a multiplicity of microscopic crevices and that the device becomes quite stable in the relation between humidity and electrostatic capacitance of the device.
