Abstract: In an electronic component feeding apparatus for feeding components with use of a taping component, a brushless motor is used as a drive motor in a tape sending mechanism that transports the taping component so as to improve productivity in an electronic component mounting apparatus equipped with the electronic component feeding apparatus. Also, an electronic component feeding apparatus is provided with a control part that automatically executes initial processing such as sending of the taping component, as well as detects and reports a sending failure of the taping component when the electronic component feeding apparatus is installed in the electronic component mounting apparatus, which makes it possible to provide an electronic component feeding apparatus enabling easy and prompt detection of the sending failure of the taping component.

Abstract: In an electronic component feeding apparatus (41) for feeding components with use of a taping component (3), a brushless motor is used as a drive motor (110) in a tape sending mechanism (43) that transports the taping component (3) so as to improve productivity in an electronic component mounting apparatus equipped with the electronic component feeding apparatus (41). Also, an electronic component feeding apparatus (241, 371) is provided with a control part (255, 355) that automatically executes initial processing such as sending of the taping component (3) as well as detects and reports sending failure of the taping component (3) when the electronic component feeding apparatus (241, 371) is installed in the electronic component mounting apparatus, which makes it possible to provide an electronic component feeding apparatus enabling easy and prompt detection of sending failure of the taping component (3).

Abstract: A conference video display system is provided for allowing attendees at the conference to switch to the video images of their respective personal computers at will, and eliminating the need for determining the correlation between the personal computers and channels of a switching unit, to provide facilitated and appropriate video switching. The system has a switching unit for receiving a plurality of video signals and selectively outputting the received video signals, and a plurality of connection cables for connecting the switching unit and a plurality of personal computers. Each of the connection cables has a selection request switch near the personal computer connected thereto to make the switching unit select the video signal from the connected personal computer as an output video signal thereof.

Abstract: A step-wise seat adjuster for automotive vehicles is made up of a stationary lower guide rail adapted to be mounted to a vehicle floor, and a movable upper guide rail adapted to be mounted to a vehicle seat and capable of lengthwise sliding movement relative to the stationary lower guide rail. Either the stationary lower guide rail or the movable upper guide rail have a lateral side portion in which are formed a plurality of regularly spaced openings. Each of the openings is surrounded by a pair of vertically spaced co-planar surfaces extending in the vertical direction and a pair of parallely spaced surfaces which are opposed with each other in the lengthwise direction. A lock mechanism is adapted to releasably engage one of the plurality of regularly spaced openings to restrict the movement of the movable upper guide rail relative to the stationary lower guide rail.

Abstract: A seat slide apparatus includes an upper rail smoothly slidable relative to a lower rail without using any balls. A part of the convex portion of the lower rail made of lightweight metal alloy material contacts the flange portions of the steel-made upper rail with an elastic spring force.

Abstract: A seat having an adjusting mechanism for adjusting the height of a head rest includes a seat cushion, a seat back connected to the seat cushion and rotatable relative to the seat cushion, a head rest disposed on the seat back and movable in the vertical direction relative to the seat back, and a mechanism for moving the head rest in the vertical direction according to the pivoting of the seat back relative to the seat cushion.

Abstract: A dry sorting machine having a separating function for removing solids of more than a predetermined size from ash and a drying function for drying the ash, and a magnetic sorting machine for removing metals from the dried ash are arranged in a pretreatment route for the ash to be supplied to the furnace. Further, there is provided a drying air pipe for introducing the high-temperature air heat-recovered from exhaust gases discharged from the ash melting furnace into the dry sorting machine. Thus, by the dry sorting machine having the separating and drying functions, simplification of the ash pretreatment process and reduction of the installation space can be achieved.
