Title: Method for detecting damage of covering of buried steel pipe
Inventor: MASUDA TOSHIICHI
IPC: G01N27/20
Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To improve the searching accuracy and the simplicity of the searching work by detecting the disturbance of the magnetic field to be generated by the leakage current by a differential type search coil, and performing the synchronous detection of the differential output with the standard signal to be transmitted to an embedded pipe as the reference signal. SOLUTION: When the AC standard signal is transmitted to a buried pipe 11, the magnetic field 13 is generated in an interlinking manner with the current 12 to be leakage-branched outside the pipe 11 by the cover damage 14. The magnetic field 13 is converted into the induced electromotive force using a pair of search coils 1a, 1b arranged so as to be in the same direction with the prescribed intervals on the ground, and minimum in sensitivity to the magnetic field 13, and inputted in the differential amplifier 2 to obtain the differential output. The differential output is simultaneously detected by a detector 4 with the standard signal 9 as the reference signal 10. Because the difference in the electromotive force is detected in this manner, the gradient of the change in the magnetic field can be detected with the intervals between the coils 1a, 1b, the sensitivity to the leakage current is improved, and the same phase noise can be removed. Disturbance of the magnetic field is detected through discrimination from the temporary one such as disturbance, and the detection accuracy is improved.

Inventor: HIGO YUZURU
IPC: F25B43/04
Filed: 1994-01-31
Abstract: PURPOSE:To enable vacuum leakage to be detected during the operation of an absorbing type cold/hot water machine by calculating an actual bleeding interval on the basis of the length of time when the absorbing-type cold/hot water machine is actually operated, so as to take it as a basic data of judgement, and by comparing the actual bleeding interval with an allowable value. CONSTITUTION:The inside of an evaporator 11 of an absorbing-type cold hot-water machine is maintained to high vacuum degree, and water (refrigerant) introduced therein is evaporated, thereby heat is taken from the periphery. The generated steam is absorbed by absorption liquid in an absorber 12, and the absorption liquid whose the concentration is diluted is fed into a regenerator 13 and heated, thereby water is evaporated. The separated absorption liquid is returned to the absorber 12. In this case, the total time Ta when the absorption cold/hot-water machine is operated from the measurement/registration starting time t1 to the measurement completed time t2, and number of times (n) wherein a bleeding device is automatically operated between the times t1, t2 are found. Moreover, the actual bleeding interval; Ir=Ta/N, is calculated, if the value Ir is smaller than tan allowable value, the vacuum leakage generation is judged.

A separate capacity could be made, for example, from silicon in the shape of corrugated tube. The method comprises sterilization of endoscopic instrument jointly with the silicone tube, which hermetizes its entered part. It will provide the further storage and transportation of instrument in a working condition. On the draft is presented a lodgement (Fig.8) for transportation of endoscope and instrument in a state of readiness to work. The proposed method of treatment, storage and transportation of endoscopes provides: for the patients - infectious safety, for the personnel - facilitation of work, for medical institutions - considerable economy of funds.
