Abstract: A wire bonding apparatus includes: a capillary, performing predetermined processing on a workpiece and movable with respect to the workpiece; an optical mechanism, moving together with the capillary; and a controller. The optical mechanism includes: a first imaging unit, acquiring a first image obtained by imaging a standard point set within an imaging range; and a second imaging unit, acquiring a second image obtained by imaging a reference point formed at a predetermined distance from the capillary. The controller positions the capillary with respect to the workpiece based on the first image, and calculates a positioning correction amount of the capillary based on the second image.

Abstract: A number of embodiments of low, stable, self-propelled vehicles adapted to carry disabled, infirmed or elderly persons. In each embodiment there is provided a load carrying floor that has its upper surface spaced below the axis of rotation of the rear wheels and which may be raised and lowered for facilitating entry onto the floor. In many embodiments, a wheelchair is adapted to be supported on the floor and a movable stop pivots upon movement of the floor between a raised and a lowered position. In each position, the stop functions to retain a wheelchair in place.
