A lighting device according to one embodiment includes a plurality of the lighting units fixed to the lighting device via a fixing frame.
Abstract:
Utility of a circuit-substrate working machine including a substrate conveyor device and a shuttle conveyor designed to shift a circuit substrate in a direction intersecting a conveying direction is improved. Based on transmission of a deliverable-state advance notification signal for one of conveyor lanes of an upstream printer, a movable conveyor lane of an intermediate shuttle conveyor is moved to a position continuous to the one conveyor lane. The circuit substrate is delivered to the movable conveyor lane in a state in which the movable conveyor lane is located at a circuit-substrate receiving position, a receivable-state advance notification signal is produced for a receiving lane for receiving the circuit substrate supplied from one of conveyor lanes of a downstream printer which has transmitted a deliverable-state advance notification signal, and a receivable-state signal and a deliverable-state signal are obtained. The circuit substrate is then delivered to the receiving lane.
Abstract:

One end part of the radiator is located between the cap part and the maximum diameter part.
Abstract:
In a material feeding mechanism in association with a continuous sintering apparatus, a material (S) carried by a transporting conveyer (1) into an atmosphere-displacement chamber (2) is fed into a furnace casing (4) of the continuous sintering apparatus by using a loading pusher (3). The transporting conveyor, the atmosphere-displacement chamber, and the loading pusher are arranged in such a manner that a direction in which the material is carried by the transporting conveyor and a direction in which the material is fed from the atmosphere-displacement chamber into the furnace casing by the loading pusher are linearly aligned, and the loading pusher and a drive unit thereof are installed under a floor of the atmosphere-displacement chamber so that the loading pusher moves up over the floor surface of the atmosphere-displacement chamber and moves forward and backward on the floor surface of the atmosphere-displacement chamber when the material is fed into the furnace casing. By such a construction, the longitudinal dimension of the continuous sintering apparatus can be made as short as possible to realize a compact design as a whole.
Abstract:

The furnace casing includes a casing body and a ceiling cover removably mounted on the casing body, and the ceiling cover can be opened in the glove box while retaining containment. A furnace member to be accommodated in the casing body comprises a combination of a plurality of divided furnace member units, and the furnace member units can be maintained by glove operations when they are delivered from the inside of the casing body into the glove box. A ceiling crane is disposed at an upper portion of the inside of the glove box, and a ceiling cover tentative space and a maintenance working space are provided in the glove box. A turntable for placing the delivered furnace member unit is preferably disposed in the maintenance working space.
Abstract:
A lighting unit according to one embodiment includes a board, a support member, and a plurality of heat radiation fins. A light emitting element is disposed on a first surface of the board. The support member has an interior surface on which a second surface of the board that is opposite to the first surface is disposed to be in contact therewith to enable heat conduction from the board to the support member. The heat radiation fins are disposed on an exterior surface of the support member substantially parallel with each other and with a clearance between each other, and each having a flat shape that extends outwardly from the exterior surface.
