摘要： PURPOSE:To manufacture oxidant injection nozzle in simple processes and yield a one which is free from crack initiation by inserting a W rod provided with a peripheral groove into a hole formed in a stainless steel rod, fitting by pressure the stainless steel rod in the W rod peripheral groove, and jointing together these two members. CONSTITUTION:A threaded groove or indented groove 16 is formed at the periphery of a W rod 21 at its one end. A stainless steel rod 11 having greater dia. than this W rod 21 is provided with a hole 17 which admits insertion of the whole rod 21, which is thus inserted therein, and a lid 12 made of W is pun under a vacuum. Seal welding 13 such as electron beam welding is performed under the vacuum, and the rod 21 is sealed in vacuum. This member is put in a high-temp. isotropically pressurized processing device and subjected to a treatment at a high temp. of approx. 1000 deg.C and with a high pressure of approx. 1000-2000atom. This compresses the stainless steel rod, which is deformed and fitted by pressure in the W groove 16, and also the rod 21 and steel rod 11 are jointed dispersively. Then this member is taken out, and a nozzle in a single body construction is yielded through machining.

摘要： PURPOSE:To prevent an injection nozzle of 6-sulfur fluoride from clogging by alkaline metal fuel, molten and scattered after igniting preheating agent, by driving a pillar type alkaline metal into the tip end of a tubular fluorine resin ring. CONSTITUTION:When 6-sulfur fluoride is injected from an injection nozzle 4 for the same, the 6-sulfur fluoride collides against the rear end of a pillar type lithium and flows through the holes 6a of a fluorine resin ring 6 while contacting with the side surface and the tip end of the pillar type lithium 10 whereby the pillar type lithium 10 and the fluorine resin ring 6 are molten and lost simultaneously within a short period of time. Thereafter the symetrical injecting combustion of alkaline metal of both sides is effected in a boiler tube. Upon preheating effected by preheating agent prior to the combustion of the alkaline metal in the boiler tube, the injection nozzle 4 of 6-sulfur fluoride is prevented from clogging by the molten and scattered alkaline metal by the pillar type alkaline metal attached to the ring 6.

摘要： PURPOSE:To obtain a power system having the low outlet pressure of a condenser and improve the power performance of an underwater navigating body by a method wherein the title power system is provided with a system accumulator, communicating with an atmosphere provided between the condenser and a feed water pump, and one piece of pipeline, communicat ing with the system accumulator and a flow passage between the condenser and the feed water pump. CONSTITUTION:The inside of a system accumulator 7 provided between a condenser 3 and a feed water pump 6 is partitioned by a bladder 7a and a space 7c is opened to the inside of the main body of a machine through an open hole 7b while the inside of the main body is evacuated initially to reduce a pressure at the outlet port of the condenser 3. The liquid chamber 7d of the system accumulator 7 communicates with the flow passage 3a of a system through one piece of line 8. The inside of the main body of the machine is evacuated and the outlet pressure of the condenser 3 is reduced. When a water system in a cycle is balanced, water does not flow through the line 8 and, therefore, a pressure loss of a pipeline in the line 8 does not exist whereby the pressure loss of the flow passage between the outlet port of the condenser 3 and the feed water pump 6 can be reduced. The pressure loss of the flow passage does not exist and the back pressure of a turbine 2 is reduced since there is no pressure loss in the flow passage whereby the performance of a power system is im proved.

摘要： PURPOSE:To permit the regulation of the fluctuation of amount of water in a cycle accompanying the speed fluctuation of an underwater navigating body by providing the title propulsive system with a system accumulator interposed between a condenser and a feed water pump. CONSTITUTION:A system accumulator 6 is interposed on a flow passage between the outlet port of a condenser 4 and the inlet port of a feed water pump 5 while the central part of the inside of the system accumulator 6 is sealed by a rubber dia phragm 6a and one space of the same communicates with a propulsive system to conduct water from the condenser 4 through the space. When water in a cycle becomes excessive in accordance with the high speed or the low speed of an underwater navigat ing body, the rubber diaphragm 6a is inflated to receive the excessive water and when the water in the cycle has become short, the rubber diaphragm 6a is contracted to send the water in the cycle out whereby the change of the speed of the sailing body can be effected smoothly since the amount of water in the cycle is regulated stably at all times. When gas is produced in the cycle or air is mixed into the water in the cycle, the air or the gas is floated and is stagnated below the rear surface of the rubber diaphragm 6a whereby the air or the gas is sucked into the feed water pump 5 and the performance of the feed water pump 5 will never be deteriorated.

摘要： PURPOSE:To enhance the performance of a propulsive system by furnishing a sub-cooler part and an over-heat condensation part in the form of piping partitioned with a header interposed, and thereby sinking the condensate temp. and the turbine back pressure without dropping the performance of an SF6 tank gasifier. CONSTITUTION:An underwater running vessel uses a propulsive system according to the closed Rankin cycle, wherein the steam at the outlet from a turbine is passed through an exhaust duct 1 and the inlet 7a to a heating condensation passage and entered to an inlet header 2 of the condenser. The steam is condensed by heating condensation passage 7 of an intermediate header 3 to become warm water, which passed through the is outlet header 4 and fed into a gasifier 6 in an SF6 tank 5. The warm water having passed through the gasifier 6 and supplied heat to the SF6 tank 5 passes the sub-cooler passage inlet 8a and a sub-cooler passage 8, and upon being over-cooled, is sent to the inlet to a water supply pump from the outlet 8b of the sub-cooler passage. Thereby the temp. of condensate and the back pressure of turbine are lowered without dropping the performance of the gasifier 6, and the performance of the propulsive system is enhanced.

摘要： PURPOSE: To enhance reliability in the r.p.m. control of a propeller by controlling the opening of an oxidizing agent control valve and a water control valve based on a detection signal from a turbine operating state detecting means. CONSTITUTION: When hexafluoro sulfur gas is supplied from an oxidizing agent tank 11 and a combustor filled with solid metal fuel (Li) generates heat, a boiler 1 heats up water supplied from a pump 8 to produce steam which drives rotation of a propeller 5 through a turbine 6 and circulates through a condenser 7. Based on the r.p.m. of the turbine detected by a detecting means 14, a controller 12 controls the opening of a water control valve 13 to keep the r.p.m. of the turbine at a specified value. Based on the steam temperature of the turbine 6 detected by a detecting means 15, the controller 12 controls the opening of an oxidizing agent control valve. Consequently, r.p.m. of the propeller of an underwater sailing body can be controlled with high reliability.
