Abstract: A light emitting device includes: a light emitting chip arranged on a substrate; a resin lens which covers the light emitting chip and focuses irradiation light from the light emitting chip; a mask which covers a region of an upper layer surface of the substrate, other than the resin lens; and a low surface tension film formed on a region of the upper layer surface of the substrate, other than in the proximity of the light emitting chip.

Abstract: A light emitting device includes: a light emitting chip arranged on a substrate; and a resin lens formed to cover the light emitting chip, wherein the center of the light emitting chip and the center of the resin lens are offset so that the centers do not match each other.

Abstract: A display apparatus includes: a cylindrical casing which is rotatably driven; and a plurality of curve-arranged displays which are installed inside the casing and have the same number as a plurality of slits formed in the casing, wherein each curve-arranged display has an L-shaped or inverted L-shaped cross-section, and short sides of a plurality of display device substrates in which a display device is installed on the short side of the L shape or the inverted L shape are arranged in the form of an arc.

Abstract: A display apparatus includes: a cylindrical casing which is rotatably driven; and a plurality of curve-arranged displays which are installed inside the casing and have the same number as a plurality of slits formed in the casing, wherein the curve-arranged displays include a light housing which is an approximately semi-cylindrical column having a hollow structure, and a plurality of display device substrates installed on an arc-shaped side surface of the approximately semi-cylindrical column of the light housing.

Abstract: A cleaning apparatus and method which includes spraying high pressure air obliquely onto a cleaning surface from an air nozzle disposed in the vicinity of the cleaning surface of a cleaning object to be cleaned. A recovery portion of the cleaning apparatus which is disposed in front of an outlet port of the air nozzle recovers at least air containing foreign matter removed from the cleaning object by making the air exhaust into an exhaust introducing passage along a wall surface of an air guide. The recovery portion of the cleaning apparatus includes an air guide section disposed in front of the outlet port of the air nozzle, and an air cover section, which forms an exhaust introducing passage for recovering the air that flows along an air guide wall surface of the air guide section.

Abstract: A cleaning apparatus includes air supply means for spraying high pressure air obliquely onto a cleaning surface from an air nozzle disposed in vicinity of said cleaning surface of a cleaning object to be cleaned; and recovery means, disposed in front of an outlet port of said air nozzle, for recovering at least air containing foreign matter removed from said cleaning object by making said air exhaust into an exhaust introducing passage along a wall surface of an air guide. The recovery means is constituted by an air guide section disposed in front of the outlet port of the air nozzle, and an air cover section, which forms an exhaust introducing passage for recovering the air that flows along an air guide wall surface of the air guide section.
