Abstract: According to one embodiment, a lighting apparatus includes a light source unit and a holding unit. The light source unit includes a substrate, light sources, and connection members. The substrate includes a main surface and a wiring pattern. The light sources are arranged on the main surface in a circular pattern, and are electrically connected to the wiring pattern. Each of the connection members is provided on the main surface, includes an insertion unit capable of being penetrated one end of a wire, and holds one end of the wire to electrically connect the wire and the wiring pattern. Each of the connection members is extended in an insertion direction of the one end of the wire, and is disposed between the two adjacent light sources so that the insertion direction intersects with a line segment which connects center portions of the two adjacent light sources.

Abstract: Alighting device includes a decoration frame, a light source unit, and a rotating ring. The decoration frame has a cylindrical shape in which a through-hole is formed. The light source unit is mounted with a light-emitting element. The rotating ring includes a supporting section configured to support the light source unit to be capable of rotating about a rotation axis that connects opposed positions of an inner wall of the rotating ring, a first annular section configured to form an inner wall that is flush with the through-hole of the decoration frame and slide on the edge of the through-hole to be capable of pivoting integrally with the light source unit, and a second annular section formed in an inner diameter larger than the inner diameter of the first annular section and configured to surround at least a part of the outer wall of the decoration frame.

Abstract: A mobile communication unit has an antenna unit including an extensible rod element and a fixed element. While the rod element is held by an antenna holder which is fixed in the mobile communication unit main body with a fixing member made of conducting material, the fixed element is attached to the inner wall of a hollow and cylindrical antenna casing. The antenna holder is inserted in the antenna casing. The feeding end of the fixed element is in contact with a projection formed outside the lower metallic portion of the antenna holder. The fixed element is fed from an RF functional block in the main body through the fixing member connected with the RF functional unit, the antenna holder and the projection. The rotational position of the feeding end around the rod element extending direction is determined and by the projection and the depression portions formed on the antenna casing and the antenna mount.

Abstract: In a linked-screw tightener in which linked screws held by a coupling belt at predetermined intervals is passed through a linked-screw guide passage provided near a leading end of and across a nose portion installed movably at the leading end of a linked-screw tightener body relative to a screwing direction, a foremost screw is fed into an open space between a pair of chuck pawls positioned in the substantially central part of the nose portion and capable of opening and closing in accordance with the movement of the nose portion relative to the linked-screw tightener body, and the supplied screw is driven with a driver bit, the screw guide unit includes: a foremost screw receiving port formed on the pair of chuck pawls wherein the foremost screw receiving port opens in the chuck pawls closing condition to allow the foremost screw to be fed into the open space between the pair of the chuck pawls; and a guide member disposed at the pair of the chuck pawls, for opening and closing the foremost receiving port to

Abstract: A drive link is coupled to an end of a ratchet wheel, and the other end of the drive link is slidably arranged in a guide hole formed in a side wall of a nose holder. The nose holder has a control plate rotatably attached to the other end of the drive link. The control plate is urged by a spring so as to engage with the other end of the drive link with such a strength as to temporarily stop the movement of the drive link when the drive link is in the course of retreating together with the nose portion. The other end of the drive link is designed to engage with a front end of the guide hole while the nose portion is in the course of advancing from a retreat end. By causing the ratchet wheel to make a forward/backward rotation based on stoppage of the drive link while the nose portion is in the course of retreating and while the nose portion is in the course of advancing, a feed wheel is rotated intermittently in a coupled screw feed direction.

Abstract: A screw tightening machine is provided which comprises a main body 2 formed on an end of a grip 1, a nose 3 mounted on the forward part of the main body 2, and a magazine 5 for guiding and feeding a band in which evenly spaced screws 4b are fitted from the side of the grip 1 to the nose 3. The nose 3 moves relatively with respect to a direction in which a screw 4b is tightened. The screw 4b is driven out from the nose 3. An end of the magazine 5 is connected to the nose 3, and a part of the other end of the magazine 5 is slidably connected to the grip 1.
