IPC: B60R1/04
Filed: 1990-06-21
Abstract: PURPOSE:To obtain the function as the mirror to reflect bright images and the excellent wear resistace and to substantially prevent the failure of the mirror even if impact is imparted to the mirror by having a metallic plate which has a mirror-finished surface and a hard protective thin-film layer which is clad on the mirror-finished surface of the metallic plate. CONSTITUTION:This mirror has the metallic plate which has the mirror-finished surface and the hard protective thin-film layer which is clad on the mirror- finished surface of the metallic plate. The mirror-finished surface of the metallic plate has a high reflectivity and >=90% reflectivity is easily obtainable. The hard protective thin-film layer clad on the surface is a thin film and, therefore, the degradation in the reflectivity of the metallic plate hardly arises. This layer can substantially eliminate the influence on the reflectivity of the metallic plate depending upon the thickness of the thin film. The function as the mirror to reflect the bright images is obtd. in this way. Since the greater part of the mirror is constituted of the metallic plate, the impact failure resistance is excellent and the mirror hardly breaks even if the impact is imparted thereto. Since the surface is coated with the hard protective thin-film layer, the excellent wear resistance is obtd.

An analysis area division means 2 makes the analysis area to be discrete by a previously shown discretizing method. Thus, it is divided into the hexahedron area of an arbitrary shape and a measure matrix defined in the respective hexahedron area is decided.  A numeric calculation means 3 solves a differential equation obtained from the Maxwell electromagnetic field equation based on the boundary condition, the initial condition or the analysis condition, which are previously defined, and therefore the distribution of the electromagnetic field is calculated in the respective hexahedron areas.

Abstract: PROBLEM TO BE SOLVED: To obtain a dental tooth surface treating agent for more surely dissolving and removing a smear layer (small cut waste) formed on a dentin cut face in mechanically cutting a dentin in root canal treatment, periodontal disease treatment and repair treatment in a dental field. SOLUTION: This dental tooth surface treating agent contains a chelating agent composed of an aminocarboxylic acid and is obtained by adjusting an aqueous solution of the chelating agent to pH >=8.5.

Title: Solid-state image sensing device

IPC: H04N5/335
Filed: 1986-07-14
Abstract: PURPOSE:To prevent the deterioration of vertical transfer efficiency by projecting one conductivity type impurity region to the optoelectric transducer side more than an impurity region for forming a buried channel. CONSTITUTION:A high-concentration P-type region 22 is extended up to the N-type region 10 side of a photoelectric conversion section 4 to an N-type region 11 for a buried channel, thus obtaining potential having the flat bottom. Signal charges in a vertical CCD are transferred to a charge storage 5b from a charge storage section 5a through a path 6a and to a charge storage section 5c from the charge storage section 5b through a path 6b. Since there is no partial indentation of potential in the CCD in a process in which charges are transferred to the charge storage section 5c from the charge storage section 5b, charges can be transferred without deteriorating transfer efficiency. Since the indentation of potential is removed, the reduction effect of a smear generated by oblique incident beams can also be expected.
