Abstract: An optical device includes an optical window, a gas/liquid supply nozzle that includes an opening from which gas and liquid are jetted and selectively jets the gas and the liquid to wash an effective region of the optical window, a disposition surface on which the optical window and the nozzle are disposed, and a first hydrophobic portion that has a hydrophobic surface property and is formed in a part of a region of the disposition surface present between the effective region and the nozzle and between two tangent lines intersecting with a jet direction of the nozzle and extending to be tangent to the effective region from both ends of the opening in a width direction along the disposition surface.

Abstract: Provided is a method for manufacturing a microneedle array, which enables efficient and stable manufacturing of a microneedle array including a needle-shaped protrusion having a constricted shape.

Abstract: A method of manufacturing a formed body for an electrode includes a first step of dropping an electrode material containing an electrode active material into a gap between a pair of transport belts and introducing the electrode material between transport surfaces of the pair of transport belts; a second step of belt-transporting and pressurizing the introduced electrode material with the pair of transport belts; and a third step of transferring the electrode material after the belt transporting and the pressurization, on a deposition belt, in which a transport direction in a transport, passage through which the electrode material is transported, of the deposition belt intersects a transport direction in a transport passage, through which the electrode material is transported, of the pair of transport belts.

Abstract: The present disclosure provides a method of manufacturing a formed body for an electrode including: a step of preparing an electrode material containing an electrode active material; a step of forming at least two projecting portions containing the electrode material and placed side by side on a support in a width direction of the support by supplying the electrode material onto the support; and a step of leveling the projecting portions on the support.

Abstract: A supply unit supplies a film strip from a film roll, and a winding unit cuts off a film strip into a fixed-length film and winds the fixed-length film around a spool to produce a wound-film assembly. An assembling unit introduces the wound-film assembly into a one-open-sided cartridge, and mounts and crimps a cap on the one-open-sided cartridge to produce a wound-film-loaded cartridge. After a pullout resistance of the film and a film length to be exposed are inspected, the wound-film-loaded cartridge is unloaded as a product.
