  • Patent number: 6374616
    Abstract: A heat exchanger for executing heat exchange between heat exchange between heat exchange bodies (6) on a heat radiation side and heat exchange bodies (3) on a heat absorption side, having low thermal resistance and high performance of heat conduction includes heat exchange bodies 6 on a heat radiation side and heat exchange bodies 3 on a heat absorption side, each being disposed hierarchically, thermoelectric conversion element modules 2 interposed between the heat exchange body 6 on the heat radiation side and the heat exchange body 3 on the heat absorption side through an insulating coat 16, and having a plurality of thermoelectric conversion elements 12, 13, wherein the insulating coat 16 is formed integrally on a surface of at least one of the heat exchange body 6 on the heat radiation side and the heat exchange body 3 on the heat absorption side, and a metal coat 17 keeping electric contact with a surface of the thermoelectric conversion elements 12, 13 on either the heat radiation side or the heat absor

  • Patent number: 5508517
    Abstract: A high resolution scanning probe type microscope capable for simultaneous observation of the optical images of a sample and the probe tip. The microscope has a construction in which the probe and the optical microscope are supported with separate supporting members and the probe is disposed inside the visual field of the optical microscope. The supporting members of the probe and the optical microscope are installed on a vibration-proof table, and the supporting member for the probe has a double-end-supported type beam construction.

  • Patent number: 5276324
    Abstract: A composite scanning tunneling microscope comprises a first objective optical system for collimating an optical flux from a sample, a second objective optical system for condensing the optical flux thus collimated, and a transparent member disposed between the first and the second objective optical systems. A through hole is perforated along an optical axis in the center of the first objective optical system. A tube scanner member has a probe for detecting a tunnel current disposed at one end thereof. The tube scanner member passes through the hole of the first objective optical system without a contact therewith. The other end of the tube scanner member is fixed to the transparent member. The tube scanner member fixed to the transparent member is separate from and independent of an optical microscope, so that a tunnel current may stably be detected without influences on the probe from vibrations of the optical microscope.
