Abstract: An electronic heating/cooling garment includes: a neck part, a collar (neckband), or an underarm part where a Peltier device (31) is placed; and a front body or a back body where a heating medium circulation path (35) and a battery (35) are placed, the battery (35) being configured to supply electric power to a pump (341) and the Peltier device (31). The heating medium circulation path (35) is composed of a flexible thermally conductive material having a tubular shape and holds a heating medium therein in an airtight manner. The heating medium circulation path has a first electrode and a second electrode on its outer surface. The first and second electrodes are configured to supply the electric power from the battery (35) to the Peltier device (31) and the pump (341).

Abstract: It is an optical information recording and reading apparatus for recording and/or reading information at a high density by using a near-field light-generating device as a near-field optical head. The end surface of the core of a flexible optical waveguide is formed in an intermediate position in the optical waveguide and in a portion fixed to the near-field optical head. Light for recording and reading information is spread within the clad. The spread light flux is reflected toward the near-field optical head by a reflective surface formed on the side of one end of the optical waveguide. The reflected light flux is collected by light-collecting structures and then is made to enter an optical minute aperture formed in the near-field optical head. Near-field light is created near the minute aperture. Light scattered by the surface of the recording medium is received. Thus, information on the recording medium can be recorded and read.
