Abstract: According to one embodiment, a superconducting coil apparatus comprising at least one superconducting coil formed of a plurality of turns under a definition that one turn is a portion of a superconducting wire annularly wound for one round, wherein: the superconducting coil has a shape along an outer peripheral surface of a tubular structure having a tubular shape; each of the plurality of turns has a coil longitudinal portion extending along an axial direction of the tubular structure; arrangement form of the coil longitudinal portion is different between a main magnetic field generation region configured to generate a main magnetic field and a magnetic field correction region configured to generate a correction magnetic field.

Abstract: The present invention is a weld line-detecting method when fillet welding by an industrial robot including a welding torch is taught. The welding torch on which an angle sensor having a contactor is attached is moved toward a welding object, angle information obtained when the contactor is in contact with the welding object is transmitted to the industrial robot, and the industrial robot moves the welding torch based on the angle information so that the angle of the contactor becomes zero. These operations are repeated, and the welding torch is moved toward a fillet part along the surface of the welding object. When the contactor arrives at the fillet part, a signal indicating that the contactor is pressed in the axial direction of the contactor is transmitted to the industrial robot. The industrial robot detects that the contactor arrives at the position to be welded on the weld line.

Abstract: To provide an evaluation chip which can eliminate the need for developing a microcomputer for mass production in addition to an evaluation chip and operate at high speeds without any limits on a chip size and the number of terminals. A microcomputer and a microcomputer scribed line are provided therein and wiring is not performed on the microcomputer on the evaluation chip. Since the microcomputer can be cut from the evaluation chip, it is not necessary to develop a microcomputer separately. Additionally, since an internal signal of the microcomputer is drawn using a glass substrate, the evaluation chip is applicable as an emulator module.
