Abstract: To provide a sheet-like optical device capable of selectively emitting light whose optical path has a changed orientation.
An optical device includes a first sheet and a second sheet. The first sheet is configured to be electrically switchable between a first state in which the first sheet extends along an in-plane direction orthogonal to a thickness direction and has transparency in the thickness direction, and a second state in which the first sheet has lower transparency in the thickness direction than the transparency in the first state. The second sheet has a prism surface on which an inclined surface inclined with respect to the in-plane direction is arranged along the in-plane direction, the second sheet facing the first sheet in the thickness direction.

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: [Object] To provide a sheet-like structure capable of highly accurately estimating a sheet-like shape.
[Solving Means] A sheet-like structure includes a sheet-like member and a plurality of detection sensors. The sheet-like member extends along an in-plane direction orthogonal to a thickness direction and receives light incident on the sheet-like member. The plurality of detection sensors are dispersedly arranged on the sheet-like member along the in-plane direction and are for detecting an incident angle of the light with respect to the sheet-like member at each arrangement position of the plurality of detection sensors.
