Title: Detecting method for boiler tube leakage
Inventor: NAGATA KAZUE
IPC: G01M3/24
Filed: 1979-12-20
Abstract: PURPOSE:To improve the boiler tube leakage detection in sensitivity by connecting sound sensors directly to the heating thin tubes or the furnace water-cooled wall of a boiler. CONSTITUTION:A plurality of sound sensors 3 are secured directly to heating thin tubes 1a, 1b... or a furnace water-cooled wall 7 which is made of the same material as said heating thin tubes 1a, 1b... and which is unitary with them. Thereby, when tube leakage occurs, the leaking noise generated when steam is blown off through the part of the heating thin tubes 1a, 1b... is transmitted through the metal structure to reach the sound sensor 3 installed nearby, amplified in an amplifier 8 and inputted to a filter circuit 9, where the signal within the acoustic frequency band which is peculiar to the leaking noise is selected, converted into a DC level in a square-law detector 10 and inputted to an alarm setting means 11 which decides it as leakage when the inputted signal level exceeds a preset level and actuates an alarm 12. Accordingly, the noise discrimination ratio and consequently the tube leakage detecting sensitivity are improved.

Title: Microwave tube
Inventor: TOMIKAWA KUNIHIRO
IPC: H01J23/027
Filed: 1987-07-02
Abstract: PURPOSE:To drop electric potential in a collector and reduce a collector loss, by installing ferromagnetic members oppositely in a partial collector front edge of a collector part, magnetizing these members with an external field, and forming a vertical deflecting field in an electron beam. CONSTITUTION:A collector part 4 is of integral type, and copper collector core 5 is set up there in close proximity to a high-frequency circuit part 2 by an insulating ring 6. And, ferromagnetic members 7 of iron or the like are oppositely installed in a front edge of the collector core 5 as symmetrically vertical to a tube shaft. The ferromagnetic member 7 comes nearer to the high-frequency circuit part 2 so that it is magnetized by a field of a focusing field device part 3, whereby a line of magnetic force passes through the ferromagnetic member 7, thus a sufficiently strong magnetic field is produced in the vertical direction of the tube shaft. This sufficiently strong deflecting field acts on a return electron from the inside of the collector core 5 and a secondary electron, so that a backflow to the high-frequency circuit part 2 is effectively prevented from occurring. Therefore, electric potential in the collector core 5 is made possible to be sufficiently lower than that of the circuit part 2, thus watt consumption is reducible.
