摘要： PROBLEM TO BE SOLVED: To manufacture a platelet injector formed such that a variable thrust injector used in control of the attitude of a flying object, such as a space shuttle, forms a single injector though two kinds of injectors to generate high and low thrust are heretofore provided. SOLUTION: A platelet injector situated at a variable thrust injector 2 is formed such that a plurality of stainless sheets each having both an injection hole with a large hole size for generating high thrust and an injection hole with a small hole size for generating low thrust are laminated together and joined together through solid phase diffusion welding.

摘要： PURPOSE:To provide a method for measuring the distance over which a flying body flies whereby measuring of the distance can be continued through simple system constitution and even with interruption of data transmission. CONSTITUTION:Distance-measuring pulses are inserted between telemeter signals B sent from a transmitter 1 located on the side of a flying body and distance-measuring pulses G are separated and extracted from telemeter signals E received at a ground side receiving unit 2 and the time difference t3 between a reference clock signal D generated at the receiving unit 2 according to the same time reference as the transmitter 1 (i.e., the clock signal periods t1, t2 of both of them are the same) and each distance-measuring pulse G is found so as to calculate the distance over which the flying body flies. The flying body does not require a transponder or the like and also there is no necessity of providing a distance-measuring tracking device on the ground and so system constitution is simple and also the distance-measuring pulses are transmitted while being involved in the telemeter signals and so there is no necessity of providing a distance-measuring signal transmission means independently and also the telemeter signals can always be reproduced on the ground and so measuring of the distance will not be disabled by interruption of signal transmission.

摘要： PROBLEM TO BE SOLVED: To provide a proper liquid break at a sensitized part for prompt level-detection by applying a sensor sensitized part of a sensor head with a water-repellent finish. SOLUTION: A sensor sensitized part 6 of a sensor head 5 is applied with a water-repellent finish. The water-repellent finish includes, for example, applying or baking of a fluorinated resin, and in the present case, it is a coating by baking of PTFE(polytetrafluoroethylene) 7 of a thickness 50-70 μm. Thus, the liquid break action at the sensor sensitized part 6 of the sensor head 5 becomes definite in change of a level sensor from in the liquid to a gaseous phase, resulting in prompt detection of liquid level.

摘要： PROBLEM TO BE SOLVED: To provide a simplified structure by operating both a motive power source and a fuel cell using hydrogen gas generated by a methanol reforming means and the energy obtained therefrom, and making common the hydrogen gas supplying system to the motive power source and fuel cell. SOLUTION: This motive power device includes a motive power source 1 having a turbine T and a fuel cell 2 to generate power using hydrogen and oxygen, works with oxygen as an oxidizer and methanol as a fuel, and is equipped with a methanol reforming means 8 which supplies the fuel cell 2 with the hydrogen gas generated by catalyst reaction of gasified oxygen and methanol and a turbine driving means to rotate the turbine as drive source using the energy of the hydrogen gas obtained from the methanol reforming means 8. Thereby both the fuel cell 2 and the motive power source 1 are operated with the hydrogen gas from the methanol reforming means 8, which enables the simplifying of the structure and the enhancing of the operating efficiency.
