Abstract: PURPOSE:To provide the antenna system able to accurately extract information of a wave source without increasing the size of the antenna. CONSTITUTION:The antenna system is formed by arranging a main antenna element 1 and a sub antenna element 2 adjacent in a direction not orthogonal to a beam scanning direction of the main antenna element 1 while beam axes are made coincident. An antenna beam of the antenna system is scanned by a scanner 3 and a reception signal from each of the antenna elements 1,2 is subjected to phase coherent multiplication processing by a phase coherent multiplication processing unit 4 and a frequency discriminator 5 outputs an output signal corresponding to the maximum frequency among output signals from the phase coherent multiplication processing unit 4 and the signal is converted by a signal processing unit 6 to obtain radio wave source information of the antenna beam direction only.

Abstract: PURPOSE:To prevent the reach of the mixing ratio of the uncombusted gas and air at an explosion limit by installing an ignition torch installed in the vicinity of the inlet of a flue in order to ignite the uncombusted gas and an injection nozzle which is installed at the inlet of the flue and jets out the gas towards the inside of the flue so that the atmosphere necessary for maintaining the combustion of the uncombusted gas ignited by the ignition torch can be supplied. CONSTITUTION:A rocket engine is ignited to launch a rocket, and the combustion gas containing the uncombusted hydrogen 4 is discharged from an engine nozzle 1, and then the uncombusted hydrogen 4 is ignited immediately by an ignition torch 2 and combusted. At the same time, GN2 is jetted from an injection nozzle 6, and the atmosphere, i.e., air flows from the outer periphery of the inlet of a flue 3 for the uncombusted hydrogen gas 4 which continues combustion, by the ejector effect, and the mixed gas is generated and flows to an outlet, passing through the flue 3. Accordingly, even in the flue 3, the uncombusted hydrogen gas 4 is perfectly combusted, without generating the shortage of air, and the harmless gas is generated.

Abstract: PURPOSE:To miniaturize, decrease and improve the safety by removing an electric ignition source and obtaining always the inner pressure explosion-proof type to hold the inner pressure. CONSTITUTION:A camera is driven by an air motor to work by air or the gas pressure of an inactive gas. Thus, an electric ignition source such as a spark is removed, the low pressure air or inactive gas are sent into a camera case 23 and a universal head 2 to surround a television camera 1, the inner pressure is always held and the inner pressure explosion-proof type is obtained. The universal head 2 is also driven by the air and the inactive gas and the safety is improved. Simultaneously, by the adoption of an air motor, miniaturization, and lightening are performed, movement and carrying are facilitated, the gas pressure to drive the motor 15 is made into the low pressure, the gas is used as the explosion-proof gas to give the inner pressure to the case 23 and the universal head 2, therefore, the safety can be enhanced.
