IPC: G06F12/00
Filed: 1989-03-30
Abstract: PURPOSE:To shorten a processing time when data being several months before are retroactively corrected by storing monthly data for each month, fixed data and a processed result to a monthly processed result file as a file for the current month. CONSTITUTION:Files 101-112 for the current month, which are composed of the fixed data of the current month, monthly data and monthly processed result, are stored to a monthly processed result file 4. When the monthly data are corrected retroactively to several months, a data correction part 5 reads inputted data in the range of a key, to which an n-month is designated, from a file 10n for the n-month and displays the data on a display. Next, the position of these display data is designated and the data are inputted. Then, an erroneous part is corrected and the corrected monthly data and fixed data are supplied to a monthly processing part 3. The monthly processing part 3 executes the reprocessing of the n-month according to these data and the monthly processed result of the file for (n-1)-month and stores the corrected monthly data, fixed data and processed result to the file for the n-month. Thus, the correction processing for each month can be successively executed up to the newest month and the processing time can be shortened.

Title: Method and apparatus for ultrasonic flaw detection
Inventor: YAMAMOTO AKITOSHI
IPC: G01N29/04
Filed: 1988-03-31
Abstract: PURPOSE:To make it possible to detect a flaw on an applied film accurately, by correcting an ultrasonic wave echo from the surface of the flaw detected from the upper part of the applied film with the changing amount corresponding to the thickness of the applied film that is stored beforehand, and grasping cracks and the like of a body whose flaw is to be detected. CONSTITUTION:The surface of a flaw of a body whose flaw is to be detected is detected with an echo detecting means 2 such as an ultrasonic flaw detector. Meanwhile, the thickness of an applied film at the part of the flaw is detected with a film-thickness detecting means 3. The detected ultrasonic wave echo is corrected with the changing amount of an ultrasonic wave echo corresponding to the thickness of the applied film which is stored in an echo-changing-amount storing and correcting means 4 beforehand. In this way, the ultrasonic wave echo which is obtained in the state without the applied film can be estimated. The flaw is accurately detected from the upper side of the applied film without removing the applied film.

Title: Safety device
Inventor: NOGUCHI AKIO
IPC: G03G15/20
Filed: 1986-04-07
Abstract: PURPOSE:To prevent malfunctions due to a leakage current, etc., and to improve reliability by using a current transformer to detect the energization of a heater. CONSTITUTION:The detection signal received from a current transformer TC is detected by a detecting part 51 as the both-end voltage (a) of a resistance R2. In a normal state of the output waveform (a), a transistor (TR) Q2 of a selecting part 54 is turned on and off by an AC/DC converting part 55. Thus a triac TR is driven with control via a phototriac PT. While a (TR) Q1 is turned on when the voltage value (f) rises up to the level of the Zener voltage ZD1 in an abnormal state of the waveform (a). Then a signal holding part 56 which keeps both TRs Q3 and Q4 in an ON state has its self-holding action. As a result, a (TR) Q5 is turned off and the contact point of a relay RL is opened to secure a protection state.
