Abstract: While a sealed package (3) prepared by wrapping conductive contents (1) with an electric-insulation film (2) is being conveyed by two conveyors (4, 4), front and rear, a conductor (5) disposed on one side of a conveyance path (A) and at least one of two conductors (6, 6), front and rear, disposed on the other side are simultaneously contacted with opposed surfaces of the sealed package (3) being conveyed. In this state, a high voltage from a high voltage source (7) is applied to the sealed package (3), and a current detector (8) is used to detect whether or not a change in current is occurring in the portion which is in contact with the conductor (5) and the portion which is in contact with at least one of the two conductors (6, 6) so as to find pinholes in the sealed package (3). Whether or not there is a pinhole in at least one of the opposed surfaces in the portion of the sealed package (3) where the contents (1) exist can be detected by simultaneous inspection from both surfaces.

Abstract: A contact sensor for a robot includes a plurality of electrically conductive shafts extending outward from a moving portion of the robot. Electrically conductive flexible feelers are disposed on the shafts. In one embodiment the feelers are disposed in fan-like arrangement similar to a peacock feather. Leakage current from a low voltage power source is used by a robot controller to sense contact with a conductive object. The robot controller immediately stops operation and movement of the robot before damage occurs.
