    • PURPOSE:To improve response by a method wherein, in a Rankine cycle type engine, when an amount of fuel fed to a burner and an amount of a heating medium fed to a turbine are regulated to control a speed, a fuel flow regulating valve is operated through PD control in which a dead zone is formed. CONSTITUTION:An output signal from a ramp function generator 10 to receive a speed command 9 is inputted to each of function generators 11-14 to output a pressure set value 15, a temperature set value 16, and valve opening set values 17 and 18. A signal generated by an PID controller 19 from a deviation between the pressure set value 15 and a turbine inlet pressure 8 is synthesized with a valve opening set value 17 causing the valve opening set value 18 to have a waste time during a given time by means of a waste time set value 25 to provide a control signal 21 to a fluid pump return flow rate regulating valve 5. A signal provided through the passage of a deviation between the temperature set value 16 and the turbine inlet pressure 8 through a dead zone setter 23 and a PD controller 24 is synthesized with the valve opening set value 18 to provide a control signal 22 to a fuel flow rate regulating valve 6.

    • PURPOSE:To reduce the volume of gases in a water condensation system and to reduce the exhaust gas pressure of a turbine by utilizing the section in a reservoir which is partitioned by a bladder as a bled gas storage chamber. CONSTITUTION:The reservoir 2 of an accumulator is branched to the pressurizing section (also used as a bled gas storage chamber) 3A and water storage section 3B of the reservoir. And at the time of starting a high pressure gas is introduced into the pressurizing section 3A of the reservoir through a high pressure gas control valve 6 to push a bladder 4, and the boiler water is jetted to a water supply pump and condenser. Right after starting a control valve 6 is changed over so as to connect the pressurizing section 3A and a submarine navigator and the steam generated in boiler pipes is introduced into the water storage section 3B and the bladder 4 is returned to its position before starting to discharge the high pressure gas of the pressurizing section 3A and to close the control valve 6 and a steam valve 7. During the operation the gases left in the condensation system are sucked from the upper section of the water storage section 3B by a vacuum pump 8 and discharged to the pressurizing section 3A. With this arrangement it is possible to reduce the pressure in the water condensition system and to reduce the exhaust gas pressure of the turbine.

    • PURPOSE:To retain a preheating agent safely by a method wherein the preheating agent, arranged in the fuel of an alkaline metal, is fixed by fixing members, reacting against the alkaline metal, consisting of a metallic material burnt by an oxidizing agent and attached to the wall of the end of a combustor provided with the injection nozzle of the oxidizing agent. CONSTITUTION:A cylindrical flange 10, having an oxidizing agent injection nozzle 9, is attached to a cylindrical ring 7, fixed to one ends of water tubes 1a, 1b, and an annular supporting member 11, fixed to the inner wall of the cylindrical ring 7, is provided with a screw thread on the inner wall thereof. A preheating agent 5 is supported by fittings 2, 3, 4 and, thereafter, the cylindrical flange 10, equipped with the injection nozzle 9 of the oxidizing agent, is secured to the end of the cylindrical ring 7 through welding or the like. The lengthwise vibration of the preheating agent 5 is prevented by the fittings 2, 3 while the lateral vibration of the same is prevented by the fitting 4 whereby the preheating agent 5 may be supported rigidly in an alkaline metal 6.

    • PURPOSE:To increase the volume of a condensation system and reduce the exhaust gas pressure of a turbine by the constitution that a bladder is pushed back to its position before starting by steam pressure. CONSTITUTION:A boiler pipe and the water storage section 3B of a reservoir are connected by a capillary through a steam valve 7. At the time of starting a high pressure gas is introduced into the pressurizing section 3A of the reservoir through a high pressure gas control valve 6 and by its pressure a bladder 4 is pushed up to the position of the partition section between a condenser 1 and water reservoir 2, and the boiler water is jetted out to a water supply pump and condenser through a water storage valve 5. Right after starting the control valve 6 is changed over so as to connect the pressurizing section 3A and a submarine navigator, and the steam generated in boiler tubes is introduced into the water storage section 3B of the reservoir through a steam valve 7 and the capillary and the bladder returns to its position before starting to release completely the high pressure gas of the pressurizing section 3A and close the steam valve 7. And during the operation the bladder 4 is pushed back to its position before starting. With this arrangement the volume of a water condensation system is secured to the maximum degree and the exhaust gas pressure of the turbine is reduced.

    • PURPOSE:To enable detection of a bearing of a hull (namely, a target) by delivering a guidance cable passing through a hose-shaped flexible material while a hose-shaped polymer wave receiver partially provided with a piezo-electric polymer is towed at a stern of a torpedo. CONSTITUTION:An interval between a towed wave receiver 5 spread with the firing of a wire guided torpedo 3 and a torpedo head wave receiver 4 is almost a quarter of a wavelength of a low frequency sound wave. In this case, a sound wave coming from a direction vertical to an axis line connecting both the receivers is incident into both the receivers 4 and 5 in the same phase. A sound wave coming parallel with the axis line is incident into the towed receiver 5 being delayed by 90 deg.. Then, by moving the torpedo horizontally or vertically, an angle varies from theta to theta ' between the axis line connecting both the receivers and an incoming direction of a sound wave. Thus, a direction of a hull can be determined by detecting a phase difference of the sound wave incident into both the receivers 4 and 5 and a change in incoming angle of the sound wave to a needle deflection of the axis line connecting both the receivers.

    • PURPOSE:To increase the volume of a condensation system and reduce the exhaust gas pressure of a turbine by installing inside a bladder push metal made of a shape memory alloy and constituting to push back the bladder to its position before starting. CONSTITUTION:A bladder 4 is installed along the left wall of a reservoir 2 and a bladder push metal 5 made of a shape memory alloy is installed so as to sit along the partition section of the reservoir 2 and a condensation chamber 1. And, at the time of starting a high pressure gas is introduced into the pressurizing section 3A of the reservoir through a high pressure gas control valve 7, and the bladder 4 is pushed up to the position of the partition section to jet out the boiler water to a water supply pump and a condenser through a water storage valve 6. Right after starting a control valve 7 is changed over so as to connect the pressurizing section 3A and a submarine navigator, and the bladder push metal 5 changes by the temperature of the condensed water its shape that follows the shape of the left wall of the reservoir 2 which the bladder push metal 5 has held in memory beforehand, and the high pressure gas in the pressurizing section 3A is released into the body sailing in water to close the control valve 7. And during the operation the bladder 4 is pushed back to its position before starting. With this arrangement the volume of the condensation/system is secured to the maximum degree and the exhaust gas pressure of the turbine is reduced.
