A jointing structure comprising multiple steps provided face to face at the coaxially built traveling path ends with an expansion gap between, multiple elastic members respectively mounted inside the multiple steps, and a joint block mounted on the multiple elastic members across the expansion gap. Multiple supporting blocks and one or more than one intermediate joint block are mounted inside the multiple steps with the joint block between. The multiple supporting blocks, the joint block and the one or more than one intermediate joint block are of concrete. The elastic members are joined together across the expansion gap. The elastic member on one side is fixed to the inside of the step on one side and then subjected to deformation toward the bridge girder axis, and thereafter, the elastic member on the other side is fixed to the inside of the step on the other side.

It is intended to prepare noodles and noodle skins, in particular, wheat flour-free noodles and noodle skins, which comprise a soybean protein composition at a high ratio. By adding a water-extracted less denatured soybean protein to noodles and noodle skins, noodles and noodle skins containing a large amount of the soybean protein can be obtained. Further, it is possible to obtain wheat flour-free noodles and noodle skins and starch-free noodles and noodle skins.

A connection method connects an optical connector and an optical transmission element. The optical connector includes a connector housing, a stop-ring structure, and an optical fiber which protrudes from an end part of the stop-ring structure. The optical transmission element includes a tensile-strength fiber body. The connection method includes fuse-connecting a first end of the optical fiber with a second end of an optical fiber protruding from a transmission element terminal part of the optical transmission element; inserting a fuse-connected optical fiber part and the tensile strength fiber body inside a reinforcing sleeve provided with a hot melt body, and covering and bridging the transmission element terminal part and at least the end part of the stop-ring structure; and integrating the fuse-connected optical fiber part, the tensile strength fiber body, the transmission element terminal part, and the stop-ring structure, by a hot melt resin melted from the hot melt body.

A projector device-of the present invention includes a light blocking mechanism for blocking leak light from a lamp unit. The light blocking mechanism includes a first light blocking member having a plurality of first light blocking plates arranged therein at certain pitches, and a second light blocking member having a plurality of second light blocking plates arranged therein at certain pitches. The first light blocking plates and the second light blocking plates each define a gap providing an air flow passage. A flat inclined part of each second light blocking plate extends in an inverted direction to a flat inclined part of each first light blocking plate, with a predetermined angle of inclination, so that the first light blocking plates and the second light blocking plates block the light emitted from the lamp unit toward a vent of a casing in all orientations.

摘要:
A projection type video display capable of reducing components in number, and attempting to improve a cooling efficiency and a silencing of the video display is provided. Three cooling fans are provided on a plate member arranged within a chassis of the video display of a liquid crystal projector. The plate member is arranged in such a manner as to be spaced apart from a bottom plate of a chassis of the video display in order to form a single external-air introducing duct. Double-bottomed structure is formed by the plate member, and the plate member is used as a bottom for arranging components. Each cooling fan sucks external air from the single external-air introducing duct, and blows the external air from a blowing duct to an object to be cooled (a light source, a liquid crystal display, and others).
