Abstract: A sheath type measuring instrument can be mounted in place easily and smoothly without the need for boring holes in an outer wall and an inner wall with high positional accuracy and also for a complex process, even if a barrel is to be fixed to the outer wall while a tip end of a sheath is being inserted in a sheath insertion hole bored in an inner wall. The sheath type measuring instrument has a sheath having a tip end for being brought closely to or into contact with a measurand for measuring a physical property of the measurand, and a barrel holding a proximal portion of the sheath for movement in a direction perpendicular to an axis of the sheath.

Abstract: Disclosed is a gas turbine engine provided with an annular pre-mixing chamber and an annular combustion chamber adapted for burning a combustible mixture from the pre-mixing chamber. A plurality of circumferentially arranged injection nozzle sets are located between the pre-mixing chamber and the combustion chamber so that the combustible mixture from the pre-mixing chamber is ejected into the combustion chamber, to cause the mixture to be burnt therein. Each injection nozzle set is comprised of at least two nozzles which are inclined with respect to each other in such a manner that a violent contact of the flows of combustible mixture passed through the nozzles occurs at a location in the combustion chamber causing a turbulence of flow to be generated therein. Thus, rapid and stable combustion can be effected.

Abstract: Disclosed is a gas turbine engine provided with an annular combustion chamber. The annular combustion chamber has, on an upstream side thereof, a first and a second row of angularly spaced injection nozzles adapted for introducing air into the combustion chamber. Fuel nozzles are opened to the corresponding injection nozzles in order to introduce vaporized fuel into the injection nozzles to form a combustible mixture therein, which mixture is ejected into the combustion chamber. Each adjacent two injection nozzles of the first and second rows are so arranged that a violent contact of the flow of combustible mixture from the adjacent two nozzles occurs in the combustion chamber.
