Abstract: A multilayer electronic component includes an element body having an internal electrode layer and a dielectric layer. These layers are substantially parallel to a plane including a first axis and a second axis and are alternately laminated along a third axis direction. A pair of side surfaces facing each other in the first axis direction of the element body is respectively equipped with an insulating layer. A pair of end surfaces facing each other in the second axis direction of the element body is respectively equipped with an external electrode electrically connected to the internal electrode layer. The insulating layer has a mountain portion formed on a peripheral edge of the side surface and a plane portion of a central portion of the side surface.

Abstract: An external electrode includes a sintered metal layer disposed on at least an end surface and a conductive resin layer disposed on the sintered metal layer. The sintered metal layer includes a first portion, a second portion, and a third portion. The first portion is disposed at a central region of the end surface. The second portion is disposed at a part of a peripheral region of the end surface, and extends to an edge portion of the end surface from the first portion. The third portion is disposed at a remaining part of the peripheral region of the end surface. The thickness of the second portion is less than that of the first portion. The thickness of the third portion is less than that of the second portion. The first portion, the second portion, and the third portion are covered with the conductive resin layer.

Abstract: This invention relates to a denitrifying composition which is a material to be used for decomposing nitrates nitrogen in effluent by sulfur-oxidizing bacteria that consume sulfur and carbonate as nutrients and is characterized by containing particles of calcium carbonate dispersed in sulfur. Preferably, the composition contains 10 parts by weight of sulfur coexisting with 10-15 parts by weight of calcium carbonate and 1-3 parts by weight of a microporous substance. This denitrifying composition can be prepared by heating powder of calcium carbonate and sulfur thereby melting the sulfur, dispersing the powder of calcium carbonate in liquid sulfur and solidifying the dispersion by rapid cooling. The composition simultaneously contains nutrients and alkali source and hence enables denitrification to proceed stably without addition of other components.
