Abstract: PROBLEM TO BE SOLVED: To obtain a compact and inexpensive discharge measuring instrument with a high measurement accuracy at UHF region by forming a flange protruding part in a trumpet shape between an opening and a flange carried by the flange protruding part and forming a first part of the external conductor of a shifting conduit on the inner surface. SOLUTION: A support body 11 is retained while it is electrically insulated by a metal cover 12 of a metal capsule which is place to a flange protruding part 4 in gaslight state. Inner and external conductors are coaxially placed at a shift pipe 8. The inner conductor is formed by the outer surface of the support body 11 and a circular plate 10 is connected to a shield conductor 14 of a measurement cable 7. The external conductor is formed mainly by the inner surface of the trumpet-shaped flange protruding part 4 at a first part and is thinner toward the tip in trumpet shape between the edge portion of an opening 5 and a flange 16 carried by the edge portion used to retain a flange cover 12. When a discharge occurs, an electromagnetic wave is generated in the metal capsule. The electromagnetic wave has a frequency band which is formed slightly stronger at UHF region in response to a high-voltage value reaching 1,000KV.

Abstract: PROBLEM TO BE SOLVED: To perform high-quality brazing without removing a stator coil by removing an existing connection device from the edge part of a rod, then inserting a first connection part into it, filling a foil into a gap between the both and performing brazing, and finally mounting a second connection part to the free edge of the first connection part by brazing. SOLUTION: An existing connection device is removed from the edge part of a rod by induction heating. Then, after a first connection part 2a for completely surrounding the edge part of the rod is inserted and engaged, a space which remains between it and the outer surface of the edge part of the rod is filled with a foil. Further, both are subjected to induction heating and are brazed by adding a brazing material. Finally, a second connection part 2b is mounted to the free edge of the first connection part 2a by brazing, thus achieving a high-quality brazing without removing a stator coil.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for providing an oscillation damper in a place, where it suffers a thermally heavy load such as in a combustion chamber by allowing a controller to influence the rotating speed and movement of a perforated plate according to pressure oscillations that depend on the load in the combustion chamber. SOLUTION: This device attenuates thermoacoustic oscillations generated, when a fuel 2 flowing into a combustion chamber 17 is burnt. A perforated plate 3, having an eccentric opening 4 through which the fuel 2 flows and rotating coaxially with a fuel conduit 1, is disposed in the fuel conduit 1 communicating with a burner 12, such that it is vertically movable with respect to the rotating axis. Rotating means 10 and moving means 11 for the perforated plate 3 are connected to means for measuring the amplitude and frequency of pressure oscillations in the combustion chamber 17 via a controller 18, which influences the rotating speed and movement of the perforated plate 3 corresponding to the pressure oscillations, which depend on the load in the combustion chamber 17.

Abstract: PROBLEM TO BE SOLVED: To reduce exhaust gas emission by feeding fuel through a passage via slits inside a fuel feeding conduit to an atomizing edge and improving the mixture of liquid fuel and combustion air, before ignition arranging distribution pins between distribution panels comprising the inside of the passage. SOLUTION: Liquid fuel is fed by a fuel nozzle to a fuel conduit 2 of an injection nozzle 1. The fuel is fed through a fuel conduit 2 via slots 6 to a distribution panel 3 forming a passage 7. Distribution pins 4 are arranged along the full length of the injection nozzle 1 in the distribution panel 3, and the fuel is distribution uniformly at the nearer side of atomizing edge 5 in the direction of the flow by the distribution pins. The thickness of the fuel films is decided by a gap width (t) of the passage 7 at the atomizing edge 5. Therefore, the liquid fuel can be fed into the injection nozzle 1 at a comparatively low pressure. As a result of this, the mixture of the liquid fuel and combustion air before ignition can be improved, and exhaust gas emission can be reduced.
