Abstract: A composite ceramic body and a method thereof are provided. The composite ceramic body comprising a first bonding body comprising a ceramic containing Si ingredient, and a second bonding body bonded to the first bonding body through a bonding material containing, as main ingredient, a Si compound which includes the element common to the Si ingredient contained in the first bonding body. The first and second bonding bodies can be bonded strongly and uniformly without any adhesive. Since the composite ceramic body has high bonding strength, it is applicable to microchemical chips and reformers.

Abstract: 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.

Abstract: 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. %.
