A capacitor includes a base having a hollow or open portion in an upper surface for containing a battery element or an electric double layer capacitor element and an electrolytic solution in an inside thereof, a metallized layer formed to a periphery of the base defining the hollow or open portion in the upper surface and a frame member made of metal brazed to the metallized layer so as to surround the hollow or open portion. An inner lateral surface of the frame member is inclined outward, and a corrosion resistant layer is deposited so as to continuously cover the inclined surface and a portion of the surface of the metallized layer situated inward thereof.

Container, battery and electric double layer capacitor

A battery case as an electronic component case includes a second conductive plate made of metal, an insulating wall having an upper end surface and a bottom end surface, a first conductive plate made of metal joined to an upper end surface of the insulating wall, and a second conductive plate attached to the bottom end surface of the insulating wall. The insulating wall has a first conductor layer formed on an entire perimeter of the upper end surface thereof and a second conductor layer formed on an entire perimeter of a lower surface thereof, an electrode formed at a peripheral portion of the lower surface of the insulating wall so as to be electrically independent from the second conductor layer, an external connection terminal brazed to the electrode, and a connection conductor formed from the first conductor layer to the electrode. The first conductive plate is attached to the insulating wall via the first conductor layer. The second conductive plate is attached to the insulating wall via the second conductor layer.

Electronic component case and battery and electric double layer capacitor

Provided is a board for ion generation that is capable of generating negative ions with much better efficiency and in an amount larger than that of positive ions. In the board for ion generation, a discharge electrode is formed on one principal surface of a substrate formed of ceramics, an induction electrode is formed on another principal surface of the substrate, the discharge electrode and the induction electrode being disposed opposite to each other, a first protective layer and a second protective layer are formed so as to cover the discharge electrode and the induction electrode, respectively. Surface discharge is generated on a surface of the first protective layer by applying an AC voltage between the discharge electrode and induction electrode, and positive ions and negative ions are alternately generated in the air. In the board for ion generation, the porosity of the substrate is 5 to 10 vol. %.

Board for ion generation and ion generating apparatus

A ceramic container includes a ceramic base having a hollow or open portion for accommodating a battery element or an electric double layer capacitor element, defined by a bottom portion and a side wall which surrounds a bottom surface of the bottom portion which bottom face faces the hollow or open portion, a ceramic coating layer formed on a periphery of the bottom face along an inner face of the side wall, a first metallized layer extending, on the bottom face, from a portion provided immediately under the side wall to an inside of an inner end of the ceramic coating layer via a portion provided immediately under the ceramic coating layer, and a conductive layer formed on the bottom face in order to cover an extended portion of the first metallized layer and the ceramic coating layer.
