Abstract: The present invention aims to provide a neuron degeneration inhibitor. The present invention relates to a neuron degeneration inhibitor comprising a compound represented by the formula (I) wherein each symbol is as defined in the description, or a salt thereof.

Abstract: It is intended to provide a compound inhibiting the activity of a protein having an amino acid sequence which is the same or substantially the same as one of the amino acid sequences represented by SEQ ID NOs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62 and so on, or its salt; a compound inhibiting the expression of a gene of the above protein; an antisense nucleotide containing a base sequence which is complementary or substantially complementary to the base sequence of a DNA encoding the above protein or its partial peptide or a part of the base sequence; an antibody against the above protein or its partial peptide; and so on. The above compound, antisense nucleotide, antibody and so on are usable as a prophylactic/therapeutic agent for respiratory diseases, etc.

Abstract: An illumination device includes a light source that emits light-source light, a light recovery member that is disposed close to the light source in the vicinity of a lateral side of the light source, and has a light receiving surface inclined at a predetermined angle with respect to an optical axis extending from the light source to the front to face the optical axis or the vicinity of the optical axis, and a rod integrator that uniformizes light-source light from the light source and light-source light reflected by the light recovery member.

Abstract: An illuminator includes a polarization converter that converts source light into first polarized light, a polarization separation member that separates the first polarized light of from the polarization converter and second polarized light different from the first polarized light, by reflection and transmission, a polarization switch member that reflects the first polarized light passed through the polarization separation member and changes same into the second polarized light, and a light guide having a first rod arranged between the polarization converter and the polarization separation member, a second rod arranged between the polarization separation member and the polarization switch member, and a third rod arranged on an optical path of the second polarized light separated by the polarization separation member.

Abstract: An illuminating apparatus includes: a light source that emits a source light; and a light guiding module that has an overlap rod portion which can pass luminous fluxes traveling in different directions therethrough and has a returning member which returns the luminous fluxes having passed through the overlap rod portion at least once so that the luminous fluxes enter the overlap rod portion in directions different from the previous time, whereby the source light is made uniform.

Abstract: To provide an image display apparatus capable of displaying images on arbitrary places while freely moving in the air. Furthermore, to allow images including a predetermined length of data to come into sight of a moving person or persons, in as natural a state as possible. The present image display apparatus includes a flying object capable of moving in the air, a projector mounted on the flying object and projecting images onto the ground (including the soil surface, floors, and walls) below the flying object, and a camera provided on the flying object and photographing places below the flying object. This image display apparatus projects and displays images from the projector on the vicinity of the person or persons recognized by analyzing images photographed by the camera.
