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 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： PROBLEM TO BE SOLVED: To provide a thruster device capable of suppressing cost increase by suppressing the number of part items and establishing a stable combustion at all times. SOLUTION: The thruster device 1 includes a body 2, thrust force changing member 3, nozzle 4, fuel supplying means 5, and an oxidator supplying means 6. The device body 2 constitutes the contour of the device 1, while the thrust force changing member 3 is supported rotatably inside the device body 2, and the nozzle 4 is connected with the device body 2. The fuel supplying means 5 is furnished with a fuel manifold 21 and a fuel injection nozzle 22 which opens at the manifold 21 and inside the nozzle 4, while the oxidator supplying means 6 is furnished with an oxidator manifold 31 and an oxidator injection nozzle 32 which is open at the manifold 31 and inside the nozzle 4. The fuel injection nozzle 22 and oxidator injection nozzle 32 are furnished with major diametric nozzles 25 and 35 having a comparatively large flow section area and minor diametric nozzles 26 and 36 having a relatively small flow section area, respectively.

摘要：【課題】摩擦撹拌点接合後にツールの表面が大気に酸化されるのを防止することにより、その酸化によるツールの劣化を抑制してツールの耐久性能を維持し、ツールの長寿命化を図る。【解決手段】一対の板材をツールのピン部で摩擦撹拌して互いに点接合する摩擦撹拌点接合装置であって、ツールを板材に向けて進退させる進退駆動器と、ツールを回転させる回転駆動器と、進退駆動器及び回転駆動器を制御する制御器とを備える。制御器は、ツールを回転させた状態で板材にピン部を押し込んでピン部に板材を加圧させる接合制御と、接合制御の後に、ツールが回転してピン部が板材に没入した状態のまま、接合制御のときよりもツールの回転数又は加圧力の少なくとも一方を減少させ、ピン部の表面温度が酸化開始温度未満になってからツールを板材から離間させる放熱制御とを実行する。【選択図】図4
