Abstract: PURPOSE:To manufacture an electrostatic float starting apparatus used in an electrostatic gyroscope and an electrostatic accelerometer in Japan and to make it possible to use the electrostatic gyroscope and the electrostatic accelerometer commonly on, the ground and on the satellite on an orbit. CONSTITUTION:A second oscillator (frequency fH) 22 is used for the specified time from the start when it is used on the ground. After the specified time has elapsed, a variable-frequency oscillator 20, which is controlled with a control circuit 33 so that an oscillating frequency fV is gradually lowered from about fH, is used. When the frequency fV

Abstract: PURPOSE:To obtain an stereoscopic image easily by combining a display panel with a polarizing filter and a display panel without a polarizing filter. CONSTITUTION:A first display panel 9 is overlapped with a second display panel 10 of the structure formed by removing a polarizing filter from the first display panel 9. The light from the first display panel 9 is controlled in the direction of polarization by the second display panel 10. When the light subjected to this control is looked at through one-way polarizing spectacles, the light is visible at one part and unvisible at the other part. If spectacles with the left eye part and the right eye part having different polarizing directions is used, the light is divided into a part visible only by the right eye and a part visible only the left eye. Two images can be thereby displayed simultaneously by forming the image for the right eye and the image for the left eye appropriately so as to enable the formation of a stereoscopic image.

Abstract: PURPOSE:To form heat resistant mixed thermal-spraying coated layer available in ultra high temp. and in an atmosphere with large temp. difference by symmetrically arranging plural powder charging holes to one thermal spraying gun and executing the thermal spraying. CONSTITUTION:In the case of executing the thermal spraying of (m) kinds (m>=2) of powders with one thermal spraying gun 1 at the same time, same kind of powder is jetted by supplying a same kind of powder through n Xpowder charging holes provided at the (n) symmetrical positions (n>=2), wherein the symmetrical axes are based on a cathode 2 as the center, and the thermal spraying is executed. For example, four charging holes are symmetrically set to the cathode (tungsten electrode) 2. Ceramic powder is charged from the faced charging holes Pa and Pc, and metal powder is charged from the charging holes Pb, Pd, and at the same time, the thermal spraying is executed. A uniformly mixed layer is obtd. over the whole zone of thermal spraying layer without developing disturbance of shape to the plasma jet. By this method, the ultra heat-resistant film for preventing the film from breakage and boundary detachment under ultrahigh temp. as well as large temp. difference atmosphere, can be formed.

Abstract: PURPOSE:To attain the integrated and highly efficient input/output, the storage, etc., of data among different programs by dividing the input/output data on the programs into plural frames of different characteristics and operating these data for each frame. CONSTITUTION:A process means 111 performs a prescribed process related to execution of programs. Thus the input data and the output data are stored in an input/output data store means 121. A correspondence information store means 131 stores the relationship between the input and output data store positions in the means 121 and the parameter names added to these input and output data. These data are also divided into plural frames according to the difference of characteristics. Then the input/output data stored in each frame are designated by the frame information via the parameter names, and this frame information is stored in a frame information store means 141. As a result, the integrated control of data is attained with out relying on programs.

Abstract: PURPOSE:To facilitate the manufacture and to arrange a propulsion device in a required position by constituting a core engine and the propulsion device separately, and by connecting them through a high pressure air duct. CONSTITUTION:A turbo fan engine 1 is constituted of a core engine 2 and a propulsion device 3 which is divided from the core engine 2. In the core engine 2, there are provided a compressor 5, a burner 6 and turbine 7 inside a case 4, and the turbine 7 is connected to the compressor 5 through a shaft 8. Thus, air which is compressed by the compressor 5 is partially introduced to the burner 6 and the turbine 7, and the rest is led to the duct 9. In the propulsion device 3, there are provided a fan 11 inside a shroud 10 and, the burner 13 and the turbine 14 inside the case 12 which is coaxial with the fan 11, and the duct 9 is connected to the burner 13. Thus, the fuel is burned by using the high pressure air in the burner 13 through the duct 9, and thereby the turbine 14 is driven.

Abstract: PURPOSE:To enable a combustion promoting effect to be as high as possible by constituting a plasma jet ignition system of an ignition nozzle body, a working fluid supply means, an arc generating electrode and a plasma accelerating means. CONSTITUTION:Working fluid containing supplied oxygen is set to the plasma state by an arc generating electrode 8 of an ignition nozzle body 6 and accelerated sufficiently by a plasma accelerating means 9 to be jetted deeply into a combustor 1. This jetted plasma injection promotes the combustion of burnt fluid flowing in the combustor with supersonic speed by the thermal and kinetic energy and chemical reaction promoting effect along with active group generation to enable ignition. Also, since the working fluid provides plasma by the arc generating electrode 8 having a negative metal electrode 12 for promoting the formation of a high melting point oxidized film, the negative electrode 12, when the working fluid containing oxygen is used, promotes the formation of the high melting point protective oxidized film on the surface without being damaged by the arc so that stable plasma jet can be injected for a long time.

Abstract: PURPOSE:To increase combustion temp. and to improve secondary combustion efficiency by binding two components; metal fuel and oxidizing agent, with a binder thereby producing the propellant consisting of prescribed ratios of the metal fuel, the oxidizing agent and the binder. CONSTITUTION:The solid propellant 1 is produced by forming pellets 4 of the metal fuel, for example, particulate boron 2 and the particular oxidizing agent, for example, ammonium peroxide 3 and binding these pellets with the binder, for example, terminal carboxyl group polybutadiene 5. The content of the boron 2 in the total weight is confined to 20-40wt.% in this case. Since the solid propellant 1 consists of the metal fuel 2 and the oxidizing agent 3 which are in direct contact with each other, the propellant allows easy combustion and generates a high temp. The binder is decomposed by this high temp. to generate the gaseous hydrocarbon of high temp. Further, the gaseous hydrocarbon of high temp. is easily secondarily burned by air by which the extremely high secondary combustion efficiency is obtd.

Abstract: PURPOSE:To improve shielding effect for neutron and strength of sintered B4C by allowing the sintered B4C to contact with a gaseous mixture consisting of a B compd., C compd., and a carrier at a relatively low temp. CONSTITUTION:For example, 4-5% in total (basing on the amt. of B4C powder) consisting of AlF3, amorphous carbon, and amorphous B is suspended in methanol, and B4C powder is changed to the suspension and mixed overnight. A starting material is obtd. by drying the mixture in vacuum, and then pulverizing and screening the dry product. Molded B4C is obtd. by treating the starting material in a die press and rubber press. The obtd. molded body is calcined at 2,200 deg.C for 30min in Ar atmosphere in a vacuum furnace, to obtain thus a sintered body having 94% theoretical density. Then, a gaseous mixture consisting of BCl3+CCl4+H2 is blown from a nozzle while holding the B4C sintered body at 1,400-1,500 deg.C. By this method, pores near the surface layer of the sintered B4C are filled with crystals of B4C, and the surface of the sintered B4C is reinforced.
