Abstract: A laser projection device includes a laser light source, a diffusion plate, and a housing. The diffusion plate has an incidence surface and an emission surface and emitted light from the laser light source is incident thereon. A plurality of linear grooves are arranged in at least one of the incidence surface and the emission surface. The housing has an opening through which light diffused by the grooves is emitted in an emitting direction of the laser light source.

Abstract: This non-aqueous electrolyte secondary battery comprises: an electrode assembly including a positive electrode, a negative electrode, and a separator; and a non-aqueous electrolyte including a non-aqueous solvent and an electrolyte salt dissolved in the non-aqueous solvent. The non-aqueous electrolyte contains a fluorine-containing chain carboxylic acid ester represented by formula 1 and a trifluoroethanol. The fluorine-containing chain carboxylic acid ester is contained in an amount of at least 10 vol % with respect to the volume of the non-aqueous electrolyte excluding the electrolyte salt, and the trifluoroethanol is contained in an amount of 0.1-2 mass % with respect to the mass of the fluorine-containing chain carboxylic acid ester. [Formula 1] RCOOCH2CF3, wherein R is a C2 or lower alkyl group, or a fluoroalkyl group.

Abstract: Light emitted from laser light source is divided by prism into two light flux and light flux corresponding to light emitted from slope and slope. Light flux and light flux are diffused by diffusion plate and diffusion plate to become light flux and light flux. By overlapping light flux and light flux, a radiation distribution with a wide angle and high light intensity can be obtained.
