摘要： A multi-layered ceramic capacitor characterized by a structure containing glass material layers imposed between adjacent ceramic layers and conductive layers which sandwich the glass material therebetween. The conductive electrode layers and/or glass material layers bind the thin ceramic film pieces during firing at lower temperatures resulting in a strong bonded capacitor having numerous electrical applications.

摘要： This invention relates to an apparatus for shielding electromagnetic radiation which includes a casing made primarily of electromagnetic shielding material and an electromagnetic wave suppressor member having high permeability and/or permittivity. A method for using this apparatus also is described. The suppressor member has a high dielectric loss and/or high magnetic loss at a location close to the place in the casing where electromagnetic waves are less shielded, thereby reducing leakage of undesirable electromagnetic waves from the casing.

摘要： An antenna assembly having patterned conductive films on the surfaces of a dielectric hexahedron with compatibility to mass-production, wherein the conductive films are formed on protuberances formed on the surface of the dielectric hexahedron on which protuberances and depressions are formed. In one embodiment, the dielectric hexahedron includes convex portions serving as the protuberances and concave portions serving as the depressions. A conductive film may be formed on the protuberances by roll coating, sputtering, evaporative deposition, and electroless deposition, thereby producing inexpensively a high quality antenna assembly having a circuit pattern formed thereon.
