Abstract: A semiconductor apparatus 100 according to an embodiment of the present invention includes a semiconductor substrate 11 and a protective layer 20. The semiconductor substrate 11 has a first surface constituting a circuit surface, and a second surface opposite to the first surface. The protective layer 20 includes a single layer of a composite material containing soft magnetic particles, and has an adhesive surface 201 to be adhered to the second surface.

Abstract: A support device, which supports a belt-shaped sheet wound around a hollow cylindrical shaft core so as to feed the belt-shaped sheet, includes a support shaft that is insertable into a hollow part of the shaft core, a frame that supports the support shaft, an antenna surface perpendicular to an axis line of the support shaft, and a loop antenna provided to the antenna surface. The shaft core includes a non-contact data carrier capable of at least one of storing and transmitting predetermined data. The loop antenna includes a loop unit coiled to define a loop surrounding the axis line. When the shaft core is seen through the loop antenna along the axis line, the loop unit is disposed in the vicinity of the shaft core.

Abstract: A support device for supporting a cylindrical member around which is wound an elongated body has: a support shaft for supporting the cylindrical member that is fitted to an external surface of the support shaft from an opening on one end in a longitudinal direction of the cylindrical member; an anchoring plates, built into the support shaft, for anchoring the cylindrical member from an inner circumferential side of the cylindrical member; and an operating means having an operation shaft of a smaller diameter than the support shaft, the operation shaft protruding forward from a distal end of the support shaft in order to operate the anchoring plates. Further, the support device has a protecting member which is attached to the distal end of the support shaft and through which is inserted the operation shaft. The protecting member further has a reduced-diameter section smaller in diameter than the support shaft.
