摘要： PURPOSE:To stabilize a vibration isolation characteristic to wide-range applied hydraulic pressure and to improve life stability to repetitive hydraulic pressure application by sandwiching artificial paper impregnated with epoxy resin between a front measure and a case, and supporting a vibrator. CONSTITUTION:A decoupling material 5 obtained by impregnating the artificial paper of 'Tetoron(R)', etc., with an epoxy adhesive is sandwiched between the reverse surface of the front measure 1 and the case 4, the vibrator composed of the flat front measure 1, a piezoelectric element 2, and a rear measure 3 is fitted in the case 4, and the whole front part which contacts sea water is covered by epoxy resin molding 6 including the case 4 to join the vibrato to the case 4. Consequently, the hydraulic pressure dependency of the resonance frequency, dynamic admittance, etc., of a vibration system is small even to wide-range applied hydraulic pressure and extremely stable characteristics to repetitive application are obtained.

摘要： 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.

摘要： 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.

CONSTITUTION:The azimuth of a target 21 and an own position 22 are used as data to estimate the motion of the target 21 by a target motion estimating apparatus 1. This estimated value is used to output the future position of the target 21 by a future position estimating apparatus 2. In order to estimate the future position, the speed component in a direction X of the target is set to A1, the initial coordinates are set to A2, the speed component in a direction Y is set to A3 and the initial coordinates are set to A4 and A1 - A4 are defined according to a predetermined evaluation functional formula. This evaluation functional formula is partially differentiated and predetermined simultaneous equations are solved to obtain A1 - A4 and the future position of the target is calculated.

摘要： PURPOSE:To reduce the time required for an unmanned, submerged cruise body to arrive at an underwater target, to increase the probability of arrival, and to enable the effect of maintaining a self-contained, submerged cruise body to be enhanced by constructing a navigation system mainly of receivers and a beam-forming circuit. CONSTITUTION:Signals from each receiver cell 20 are given different delay characteristics by a beam-forming circuit 44 and are added together by a signal processing circuit 45 for square detection. From the level of the output of the circuit 45, it is determined whether or not a target exists, and the azimuth of the target can be determined from the circuit 44. Signals of a front array 21, side arrays 22, 23 and a nondirectional receiver 31 (these signals can be used in detection in all directions, reduce time, and are used in maintaining a submerged cruise body in the perpendicular position), are inputted to an integral processing circuit 50. Interpolation is carried out according to the position of the target and final estimation of the azimuth is carried out so as to estimate the azimuth and distance of a submerged cruise body which is the target. Azimuth and distance information from the circuit 50 is inputted to a motion control circuit 51 to drive an unmanned submerged cruise body 1. Then an active mode is started and the unmanned submerged cruise body accompanies and tracks the target submerged cruise body 1.

摘要： 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.

摘要： 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.
