Abstract: PROBLEM TO BE SOLVED: To provide a burner apparatus excellent in flame insulation capability and performing stable combustion even when the amount of injection of fuel gas is reduced. SOLUTION: There are provided first nozzle means 10 for specifying a first flow passage 45, second nozzle means 12 for specifying a second flow passage 47, an injection nozzle body 20 having an injection hole 48 for injecting fuel gas, and an air flow passage 8 for supplying air to the first and second flow passages 45, 47. When the amount of supply of fuel gas is little, an injection speed thereof is reduced, and the fuel gas flows into the first flow passage 5 by receiving action of the air stream flowing through the first flow passage 45, while, when the amount of supply of the fuel gas is much, an injection speed thereof is increased, whereby the fuel gas surmounts the air stream flowing through the first flow passage 45 and flows through the second flow passage 47.

Abstract: PROBLEM TO BE SOLVED: To enable a base material to be doped with impurities surely at a required doping amount, that is, with good controllability uniformly by making impurities react on a constituent element of a base material once to be a compound and adding and dispersing it to a base material. SOLUTION: High frequency current is supplied to a high frequency coil 2 and the coil is heated. In the process, at first, it is heated at a temperature which is lower than a fusing point of a base material 5 and higher than a fusing point of impurities 4. A compound Na2 Te is produced by making Na of the impurity element material 4 and Te of a base material react in this way. Oxidizing property of the compound is greatly weak when compared with Na only and becomes a stable substance. Then, heating of a high temperature is carried out. The high temperature heating is carried out at a temperature which is higher than a fusing point of Pb and Te of a base material for dissolving all the raw material inside a crucible 1 and contents inside the crucible 1 are fully agitated and mixed while the high temperature heating is maintained. Thereby, impurities of Na can be dispersed uniformly and entirely into a base material of PbTe.

Abstract: PROBLEM TO BE SOLVED: To perform an aerodynamic vibration test where the vibration characteristics are simulated while coupling a winged airplane and a rocket by supporting a machine body simulating a winged airplane, i.e., a rocket model simulating the shape of a rocket for mounting a winged airplane at the forward end thereof, at a predetermined position in a wind tunnel. SOLUTION: A machine body model 1 is set in a wind tunnel while being coupled with a sting 3 simulating the rocket body through a coupling part simulating the nose of rocket. A spring 7 simulating the coupling rigidity of a winged airplane and rocket is built in the sting 3. The machine body model 1 is secured, at the rear end thereof, to a supporting metal 4 and coupled in the sting 3 while being blocked by means of a central rotary shaft 6 disposed in the inner tube 5 of sting 3 and allowed only pitch rotation. Since such a structure is employed, aerodynamic force simulating the air flow being effected by the rocked acts on the machine body model 1 and the machine body model 1 can vibrate rotationally with micro amplitude.

Abstract: PURPOSE: To smoothly perform the remote control by verifying and re-editing an indication instruction string of remote control in real time to avoid the occurrence of a trouble and re-editing the indication instruction string leading to the trouble. CONSTITUTION: When an operator operates a controller 10, a remote control command is sent to an operation management mechanism 14 through an operation simulator 12 of a robot, and it is verified whether the command has a trouble which can be discriminated or not. If the command has no troubles, it sent to a holding and delay mechanism 16 and is held for a virtual delay time. If the remote control command has a trouble, a trouble processing function is operated. The operation management mechanism 14 is connected to the holding and delay mechanism 16, and a trouble processing method like deletion or change of a series of control commands leading to the trouble in the mechanism 16 can be adopted. Consequently, remote control commands are verified and re-edited in real time, and the remote control system of high operability is obtained.
