Abstract: A thermal electric power generator 100 is installed at a location to which heat based on the heat generation by the engine 50 of a motor vehicle with thermal electric power generator 200, 300 is transmitted, the thermal electric power generator 100 comprising an electron emitter 2 for emitting electrons when heat is applied to the electron emitter 2 and an electron collector 3 for collecting the electrons emitted from the electron emitter, wherein by using the electron collector as a negative electrode and the electron emitter as a positive electrode, the electrons are caused to migrate from the electron collector to thereby generate electric power, and the electric power generated by the thermal electric power generator is supplied to the motor vehicle with thermal electric power generator.

Abstract: A carbon nanotube manufacturing method is employed, in which a carbon nanotube manufacturing apparatus (1000, 2000, 3000) comprises an ionizing means (e.g., a negative ion generator (10)) for ionizing a vapor of a certain carbon-containing compound, an electric field generating means (e.g., a direct-current power supply (21), a cathode (22) and an anode (23)) for generating an electric field and a heating means (e.g., a high-frequency heater (30)) for heating a growth substrate (50, 55) disposed within the electric field generated by the electric field generating means, and in which a vaporized gas of the carbon-containing compound, the vaporized gas being ionized, is caused to pass through the electric field and to come into contact with the heated growth substrate, so that a well aligned growth of carbon nanotube (4) on the growth substrate can be obtained.

Abstract: A solvent containing low-boiling and high-boiling impurities in an evaporating section, so that the high-boiling impurities is left as a tank bottom waste, and a solvent vapor from the section is guide through a mist separator into a condenser. A condensate produced in the condenser is returned to the mist separator so as to serve as a mist catching liquid. A fraction not having condensed in the condenser is fed to a rectifying section where fractional condensation is performed so that the low-boiling impurities are condensed to be removed. A remainder of the solvent vapor from which the impurities have been removed is also condensed and recovered for reuse in the resist washing/exfoliating step during manufacture of liquid crystal devices or IC, so that the soiled solvent need not be discarded or treated in a remote cite, thereby facilitating the process or the step using the solvent.
