Title: Method for measuring thickness of oxide film by glow discharge
Inventor: ARAYA SHOICHI
IPC: G01B7/26
Filed: 1995-03-24
Abstract: PURPOSE: To accurately and rapidly measure the thickness of oxide film generated on the surface of a metal material without any destruction by utilizing a fact that the sputtering speed of a base material differs from that of the oxide film and using glow discharge. CONSTITUTION: In glow discharge, the sputtering speed of a metal base material generally differs from that of oxide layer under constant discharge conditions. Since the sputtering speed of the base material is faster than that of oxide film, a straight line with a larger inclination than that indicating the sputtering speed of oxide film is obtained. The difference in the inclination of two straight lines can be clearly distinguished and the inclination can be obtained by the least square method. A cross point F can be obtained by extrapolating the two straight lines. Since the inclination of two straight lines, namely the sputtering speed differs with the cross point as a boundary, depth (df) of a sputtering mark for the cross point becomes the thickness of oxide film.

Title: Sight-line guide sign
Inventor: IMAZU RYUJI
IPC: E01F9/00
Filed: 1995-03-27
Abstract: PURPOSE: To prevent the adhesion of snow by projecting an approximately horizontal short-sized cylindrical case in front from the periphery of a reflecting plate while inclining the front end of the cylindrical case at a specified angle, where an upper side wall is projected in front from a vertical surface. CONSTITUTION: Since the front end of a cylindrical case 4 is formed in an inclined plane, the stagnation point of a wind is moved every time the strength and directions of the wind differ, snow does not stagnate at one place, and snow is difficult to adhere on the surface of a reflecting plate 3. When the angle of the inclined plane of the case 4 is set at 15 deg.-60 deg. to a vertical surface, dust and snow are difficult to adhere particularly. The case 4 is formed detachably and removed and stored with the exception of a snowfall period, and the reflecting plate 3 is easy to be viewed while cracking is prevented even when stone, etc., collide by molding the case 4 of a colorless transparent polycarbonate resin, etc.  When the reflecting surface of the reflecting plate 3 is tilted in the oblique downward direction at an angle of 15 deg.-60 deg. to the vertical surface, snow is difficult to adhere on the reflecting surface. Accordingly, the adhesion of snow on the reflecting plate can be inhibited and can be made easy to be viewed, and damage can be prevented.
