Abstract: An object of the present invention is to reduce or eliminate a defect (e.g., a void) by achieving (i) a semipreg and a prepreg each of which allows a reduction in residual volatile component and (ii) methods for producing the semipreg and the prepreg, respectively, and consequently to achieve (iii) a fiber-reinforced composite material which has high heat resistance and superior mechanical strength and a (iv) a method for producing the fiber-reinforced composite material. The present invention attains the above object by providing, for example, a semipreg containing: powders of an imide oligomer; and reinforcement fibers, the imide oligomer being represented by a specific general formula (1).

Abstract: A fuel injection device for a gas turbine combustor includes: a pilot fuel injector; a main fuel injector; a plurality of main fuel injection holes arranged in the main fuel injector to inject the fuel rearward; a main fuel injection nozzle to guide the fuel to a main air passage, protruding rearward from a circumference of the main fuel injection hole into the opening formed in a passage wall that forms the main air passage; a heat-shielding casing covering the main fuel injector; and a ring member interposed in an axial gap between the passage wall and the heat-shielding casing. The ring member covers a through-hole gap between the main fuel injection nozzle and a through-hole in the heat-shielding casing, and has a purge passage communicated with the opening to introduce air into the main air passage.

Abstract: Provided is a jet system capable of regulating a pressure of a jet substance without using any high-pressure gas supply subsystem. In a storage section for storing therein a jet substance such as fuel or oxidizer, a pressurizing substance such as liquefied gas is stored in addition to the jet substance, to enable the jet substance to be supplied from the storage section according to pressurization from the pressurizing substance. A jet operation is performed while an internal pressure of the storage section lowered along with discharge of the jet substance therefrom is at least partially recovered by at least a part of the pressurizing substance vaporized in the storage section.

Abstract: When distribution material is distributed over a target site on a ground surface from an aircraft, a distribution supporting apparatus offers support information to a pilot dropping the distribution material to efficiently distribute the distribution material. The distribution supporting apparatus includes: an input section to which information items on at least an aircraft velocity, an aircraft altitude, and a wind velocity are input; a computation section configured to compute a location at which the distribution material dropped from the aircraft arrives on the ground surface and a density distribution of the distribution material on the ground surface based on the information items input to the input section; and a display control section configured to display, on a display, the support information relating to the location and density distribution computed by the computation section.

Abstract: Provided is a high-frequency wave feeding system capable of feeding microwaves with little loss and without addition of resistive noise, using a simple deployment mechanism. The system includes a first waveguide fixed to a first structure of a deployment structure and having a choke flange, and a second waveguide fixed to a second structure of the deployment structure and having a cover flange. When the deployment structure is in a deployed state, the choke flange and the cover flange face each other so that high-frequency waves are fed to the deployment structure via the first and second waveguides.
