Provided are a ceramic wiring substrate having a side surface which realizes reliable chucking or hooking; a multi-piece wiring substrate array for providing a plurality of the wiring substrates; and a method for reliably producing the multi-piece wiring substrate array. The wiring substrate is formed of a ceramic material, has a square (rectangular) shape in plan view, and which has a front surface, a back surface, and side surfaces each being located between the front surface and the back surface, wherein each side surface has a belt-like uneven surface including a plurality of alternate and parallel convex portions and concave portions which are formed so as to extend along the front surface, and also has a fracture surface located on a side toward the back surface.

Provided are a ceramic wiring substrate; a multi-piece ceramic wiring substrate array for providing a plurality of the wiring substrates; and a method for reliably producing the wiring substrate array. The ceramic wiring substrate includes a substrate main body, which has a front surface, a back surface, side surfaces, a groove surface located on a side toward the front surface, and a fracture surface located on a side toward the back surface; and a notch which has a concave shape in plan view, and which is provided on at least one of the side surfaces so as to extend between the front surface and the back surface, wherein, in the side surface having the notch, the boundary between the groove surface and the fracture surface has curved portions on opposite sides of the notch, the curved portions being convex toward the front surface of the substrate main body in side view.

A solid-state image pickup device includes a photoelectric conversion portion for generating signal electric charges in accordance with an amount of incident light, a plurality of color filters, and a flattening layer formed on the plurality of color filters. A thickness of a projection or a recess on a surface of the flattening layer, provided on a region where color filters are adjacent to each other, is equal to or less than 0.2 μm.
摘要:
Lipolytic enzymes with high activity at alkaline pH in the absence of Ca++ can be obtained from filamentous fungi of the genera Gliocladium, Verticillium and Trichophaea and that the lipolytic enzymes are effective for improving the effect of detergents. The lipolytic enzymes have a good washing performance, as expressed by the hydrolysis of oil on textile swatches. The amino acid sequences of the lipolytic enzymes are highly homologous.
