Abstract: PURPOSE:To detect an embedded pipe fitting through a comparatively simple process by providing two types of detection holes in the neighborhood of the presumed position of embedment in the arrangement alongside the presumed embedded direction of the pipe in connection, and inserting a signal transmission and a reception coil in these holes. CONSTITUTION:A plurality of gas sensor holes 3 are bored in the arrangement alongside the presumed embedded direction of a gas pipe 1, wherein the direction is presumed on the basis of the drawing data and the odor intensity of the applicable gas, and gas concentrations are sensed by a gas sensor 5. No.1 and No.2 detection holes 6, 7 are provided extending to the lower parts of those three or more which have the largest concentration, among which two or more shall be detection holes 7. A signal transmission and a reception coil 11, 12 are inserted in them, and if the coil 11 is energized by a transmission side circuit 13, an induction current is generated in the gas pipe 1. Thereby the mag. field generated around the gas pipe 1 is sensed, and the values obtained from different detection holes 7 are subjected to comparison, and it is presumed that embedded pipe fitting 2 is located between gas pipe parts corresponding to the division where a large difference is sensed. This eliminates necessity for sensing of the gas pipe 1 separately and also provision of a hole situated right over, which should shorten the working processes.

Abstract: PROBLEM TO BE SOLVED: To insure element separation characteristics and obtain good electric characteristics, by a method wherein a side wall of a groove of a semiconductor substrate is sequentially bent while constituting a taper angle from a surface of the semiconductor substrate to a bottom of the groove and the taper angle satisfies specific conditions. SOLUTION: A gradient angle (taper angle) of a side wall of a groove 2 having a side wall bent in three stages is directed from a surface of a semiconductor substrate 1 toward a bottom of the groove 2, wherein it is constituted to sequentially bend with angles A1, A2, A3 from the surface of the semiconductor substrate 1, and comes into contact with the bottom which is a face parallel to the surface of the semiconductor substrate 1. The taper angles A1, A2, A3 satisfy relations of A2>A1, A2>A3 and A1<83 deg., whereby an element separation region of good electric characteristics can be obtained. Thus if a gate insulation film is formed by oxidizing the surface of the semiconductor substrate after formation of the element separation region, reduction in film thickness can be suppressed at a border between the element separation region and an active region.
