Abstract

Abstract A galvano-magnetro effect apparatus comprised of a substrate with excellent electric insulating ability, at least one galvanomagnetro effect device which is fixed on the substrate, a magnet which is provided opposite to the device so that the magnetic flux is applied to the device and the density of the magnetic flux may be varied, and a load which is fixed on the substrate while being isolated from the device so that it is not affected by the magnetic flux of the magnet and is connected to the device with a conductor.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 123 words
A galvano-magnetro effect apparatus comprising a. a unitary substrate with excellent electric insulation characteristics; b. at least one galvano-magnetro effect device which is fixed on the substrate; c. a magnet which is provided to oppose the device so that the magnetic flux can be applied to the galvano-magnetro effect device and the density of magnetic flux can be varied; d. at least one load which is fixed at a position isolated from the galvano-magnetro effect device on the substrate so that the load is not exposed to the magnetic flux of the magnet; e. a conductive path which electrically connects the load and the galvano-magnetro effect device, and f. means to connect the galvano-magnetro effect device and the load to an external circuit.
Claim 2
Dependent Claim 123 words
A galvano-magnetro effect apparatus comprising a. a unitary substrate with excellent electric insulation characteristics; b. at least one galvano-magnetro effect device which is fixed on the substrate; c. a magnet which is provided to oppose the device so that the magnetic flux can be applied to the galvano-magnetro effect device and the density of magnetic flux can be varied; d. at least one load which is fixed at a position isolated from the galvano-magnetro effect device on the substrate so that the load is not exposed to the magnetic flux of the magnet; e. a conductive path which electrically connects the load and the galvano-magnetro effect device, and f. means to connect the galvano-magnetro effect device and the load to an external circuit.
Claim 3
Dependent Claim 15 words
