Abstract: An accumulation region (15) comprises many dispersed dots (15a) whose surface density is higher than that of structural pin-holes produced in a tunnel insulating film (14a). Alternatively, the number of dots (15a) in the accumulation region (15) is determined to be five or more. Alternatively, a conduction region (13c) is formed in a polysilicon layer (13) whose surface roughness is greater than 0.1 nm and less than 100 nm. The number of dots (15a) in the accumulation region (15) is larger than the number of grains in the conduction region (13c). Even if defects, such as pin-holes, occur in the tunnel insulating film (14a) and charges accumulated in some dots leak, the charges accumulated in the dots in the regions where no defect is present do not leak. Therefore, information can be held for a long time.

Abstract: PURPOSE: A brass pin is provided to maintain an engine oil clean and improve thermal efficiency while inserting a brass pin into a compression ring of an engine piston of a thermal engine. CONSTITUTION: A brass pin is inserted at both ends of a compression ring of an engine piston. The compression ring has at both ends thereof grooves of 2cm or shorter, and at an interior thereof a lengthened groove for insertion of a brass pin. The brass pin has a coefficient of linear expansion larger than that of a steel ring. Therefore, if the brass pin inserted into the steel ring expands by a heat, the steel ring is pushed toward both sides, thus allowing the brass pin to tightly contact a cylinder wall. The brass pin blocks both ends of the steel ring so as to thereby increase compression force and improve thermal efficiency.
