Title: Estimation of corrosion state of steel material in concrete
Inventor: YAMAMOTO SATORU
IPC: G01N27/26
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To simply and accurately estimate the corrosion state of a steel material such as a reinforcing rod or the like in a concrete structure caused by the neutralization of concrete or the penetration of chloride ions by a corrosion sensor. SOLUTION: A fine wire 4 comprising the same material quality as a steel material in a concrete structure 9 is embedded in the concrete structure 9 and a point of time when the fine wire 4 is cut by corrosion is measured. The cutting of the fine wire 4 is judged on the basis of a point of time when the flow of a current passed across both ends of the fine wire 4 is stopped or suddenly reduced.

Title: Object program reduction system
Inventor: MIYAZAKI YOSHIAKI
IPC: G06F9/45
Filed: 1988-12-16
Abstract: PURPOSE:To increase the executing speed of an object program by converting (merging) plural continuous combinations of comparison instructions, etc., into a combination of comparison instructions, etc. CONSTITUTION:A data assignment means 4 assigns each data onto an object program and sets the assignment address and the assignment length of each data at an assignment table 5. Then an instruction merging means 8 decides whether plural continuous combinations of instructions, etc., can be merged or not by reference to the table 5 where the assignment addresses and the assignment lengths are set for each data by the means 4. If the merging of combinations is possible, these continuous combinations are merged into a combination of comparison instructions, etc. Thus it is possible to reduce the object program produced by a compiler and to increase the executing speed of the program.

Title: Mechanism for delivering paper sheet
Inventor: NANSHIN ISATO
IPC: B65H3/06
Filed: 1988-12-16
Abstract: PURPOSE:To prevent the generation of wrinkles on the rear end center portions of paper sheets at the time of delivering same by making the paper-sheet sending force of the inside-portion roller of delivering rolers smaller than that of the outside-portion rollers thereof. CONSTITUTION:As paper sheets 1 which are housed in a housing portion 2 being alignedly stacked are pressed by a pressing board 7, the paper sheets 1 are pressed against delivering rollers 9 and pick rollers 8 and delivered by the rotation of these rollers 9. In this case, even if the pick rollers 8 start to deliver the center portions of paper sheets 1, since the sending force of the inside-portion roller 90 of the delivering rollers 9 is made smaller than the sending force of the outside-portion rollers 90 thereof, the preceding movement of the center portion of the paper sheets 1 by means of the pick rollers 8 will not take place but both end portions tend to precede. As a result, the paper sheets 1 are sent to a separator 8 with the rear end center portions thereof being pulled back, to correct skewing and prevent double feeding. Hence, the generation of wrinkles can be prevented while preventing the occurrence of jam.
