Title: Airtight device in heat insulating wall
Inventor: MOTOZUNA KAZUMICHI
IPC: F17C13/12
Filed: 1983-07-22
Abstract: PURPOSE:To increase a heat insulating effect as well as to improve safety, by holding a heat insulating wall on an airtight structure at normal times, while installing such an airtightness breaking mechanism as making a leaked liquid pass through automatically at a time when a tank leaks. CONSTITUTION:Usually, a heat insulating layer's clearance 9 is airtightly cut off from the outside air by a film 14. Therefore, there is no fear of producing a large convection current so that a heat insulating effect is surely maintainable. In case leakage from a tank occurs, the leaked liquid flows toward the clearance 9 around a support block 6 along the top of a heat insulating layer 3, then passes through the clearance 9 and is discharged to the inside of a troughlike mechanism 12 whereby it is collected on the film 14. Hereat, this film 14 is cooled to somewhere around minus 160 deg.C and is self-destroyed, thus the leaked liquid falls plumb down onto a leaked liquid receiver 9 and colled therein. Accordingly, a support block 5 and an inner plate 4 both are in no case exposed to the leaked liquid any longer and safety is thus improvable.

Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To instantaneously accurately detect a fault by detecting and discriminating a fault when a detected current difference of a plurality of DC current detectors provided in connected multiple rectifiers exceeds a predetermined threshold value. SOLUTION: A transformer 2 is connected via a circuit breaker 1, multiple rectifiers 3 are connected to the transformer 2, and a power is supplied to a load 6. A DC current detector 4 is provided at output sides of the rectifiers 3. When current references of the A1, A2 of the rectifiers 3 are the same, the currents A1, A2 are detected by the detector 4. This currents are insulated from a rectifier main circuit by insulating amplifiers 9C, 9D, and converted into a desired signal level. A subtracter 14 detects a difference of them. A comparator 15 compares the value with a threshold value set by a fault discrimination setter 16, and discriminates it as a fault detection of the detector 4.
