Abstract: A plurality of land portions is formed on a tread portion of a pneumatic tire by main grooves extending in a tire circumferential direction and lateral grooves extending in a tire width direction. At least one stepped portion which is lowered on a downstream side in a water drain direction is formed on at least a portion of a groove wall which forms the land portion.

Abstract: A light emitting device includes a light emitting element; a light reflecting member having an Ag-containing layer on a surface thereof; and a protective film having a thickness of 1 nm to 300 nm and covering a surface of the light reflecting member, the protective film covering a surface of the light reflecting member, in which the Ag-containing layer has a thickness of 0.1 ?m to 0.5 ?m.

Abstract: A pneumatic tire includes a sidewall portion extending in a tire radial-direction. The sidewall portion includes a plurality of projecting portions projecting in a tire width-direction, and at least one reinforcing portion which is at least partly different in a projecting amount from a projecting amount of the projecting portions at the same position in the tire radial-direction, and is connected to the projecting portion in a tire circumferential-direction.

Abstract: A light emitting device includes a light emitting element; a light reflecting member having an Ag-containing layer on a surface thereof; and a protective film having a thickness of 1 nm to 300 nm and covering a surface of the light reflecting member, the protective film covering a surface of the light reflecting member, in which the Ag-containing layer has a thickness of 0.1 ?m to 0.5 ?m.

Abstract: A method for manufacturing a light emitting device includes: integrally molding a package and a lead, the package arranged to form at least part of an inner peripheral face of a recess portion in which the light emitting element is housed, the package including a base material and a plurality of particles, the base material including a resin, a coefficient of thermal expansion of the particles being different from a coefficient of thermal expansion of the base material; and covering the inner peripheral face of the recess portion with a cover film, the cover film having light transmissive and electrical insulation.

Abstract: A method for producing a light emitting device includes spraying a resin mixture onto a light emitting element using a pulse spraying method to deposit the resin mixture on the light emitting element. The resin mixture includes a thixotropy imparting agent. The resin mixture is cured to form a light transmissive member via which light emitted from the light emitting element is to transmit to an outside of the light emitting device.

Abstract: A light emitting device has a light emitting element, a package, a lead, and a cover film. The package is arranged to form at least part of an inner peripheral face of a recess portion. The light emitting element is housed in the recess portion. The lead is disposed on a bottom face of the recess portion. The lead is electrically connected to the light emitting element. The cover film is arranged to cover the inner peripheral face of the recess portion. The cover film has light transmissive and electrical insulation. The package includes a base material and a plurality of particles. The base material includes a resin. A coefficient of thermal expansion of the particles is different from a coefficient of thermal expansion of the base material. The particles are disposed at least near the inner peripheral face of the recess portion.

Abstract: A wave-length conversion inorganic member can includes a base body and an inorganic particle layer on the base body. The inorganic particle layer can include particles of an inorganic wave-length conversion substance which is configured to absorb light of a first wave-length and to emit light of a second wave-length different from the first wave-length. The inorganic particle layer can include an agglomerate of a plurality of the particles. Each of the plurality of the particles are in contact with at least one of the other particles or the base body. A cover layer comprises an inorganic material, and the cover layer continuously covers a surface of the base body and surfaces of the particles. The inorganic particle layer has an interstice enclosed by the particles, or by the particles and one of the base body and the cover layer.

Abstract: A turbofan includes a boss rotatable about an axis, a main plate connected to the boss, a shroud having an intake hole, and a plurality of blades arranged between the main plate and the shroud. An undulating protrusion portion is arranged at a front edge portion of each blade. The undulating protrusion portion includes a plurality of protrusions. The pitches of the plurality of protrusions are formed so as to become smaller as approaching to the main plate side.
