Abstract: A cassette comprises a sheet housing portion that has an opening in an upper face and houses sheets, a cassette cover that can be attached and detached and covers at least a portion of the opening, a first protruding portion that is provided in one edge portion of the cassette cover and protrudes toward a bottom face of the sheet housing portion, and a second protruding portion that is provided in the other edge portion of the cassette cover and opposes the first protruding portion, wherein the sheet housing portion includes a projection-shaped portion that protrudes toward the first protruding portion and a position regulating portion that has a gap into which the second protruding portion enters, and the first protruding portion is provided with a receiving portion into which the projection-shaped portion enters.

Abstract: A light emitting device includes first and second light emitting elements; and a light guiding member including first and second light receiving portion corresponding to the first and second light emitting elements and configured to emit the light received by the first and second light receiving portions from a light emitting portion via a light guiding portion. The light guiding portion includes a reflecting surface forming portion between the first light receiving portion and the second light receiving portion in the first direction. The reflecting surface forming portion includes first and second reflecting surfaces. The first reflecting surface is formed by surfaces having different angles including a surface that reflects the light from the first light receiving portion to a side of the first light receiving portion.

Abstract: A method for degrading a polymer by bringing same into contact with a solid phase composed of a carrier, a microorganism and an aqueous solution. The aqueous solution contains nutrients required for the growth of the microorganism and water. The carrier has a maximum water retention of at least 40 wt. % but at most 4,000 wt. %, the aqueous solution is retained in the carrier in an amount of at least 10% but at most 100% of the maximum water retention of the carrier, and the solid phase has a percentage of interstices of 25% or greater but smaller than 100%.

Abstract: Cells of a novel strain of Drechslera monoceras having practical weed controlling activity against barnyard grass (Echinochloa spp.) at temperatures ranging from 26° C. to 35° C., and exhibiting no pathogenicity to major crops, including rice, are used as a herbicidal component.

Abstract: A herbicide containing phytopathogenic microorganisms for surface application on water was obtained by a method in which the phytopathogenic microorganisms, which have virtually no adhered surfactant and are pathogenic against non-useful plants having a hydrophobic surface, are adhered to or combined with a submersible base.
