Filed: 1992-11-26
Abstract: PURPOSE:To compensate some power consumption and to make an effective use of energy by making a good use of undesired ultraviolet rays and infrared rays transmitted behind a reflector and generating electric power. CONSTITUTION:A wavelength-selective vapor-deposited film is applied on the reflector 2. Thus, light in the visible region is reflected and becomes collimated beams, and the ultraviolet rays and the infrared rays are transmitted. And a solar battery panel 11 is irradiated with the transmitted ultraviolet rays and infrared rays. Light energy is transduced to electric energy by the solar battery panel 11 by an opto-electric transducing effect. The generated power is supplied to a fan 12 for cooling a liquid crystal panel so as to drive the fan 12. It is allowable that the power generated by the solar battery panel 11 is used for the other purpose in addition to the fan driving, in short, it is preferable that some power consumption of the liquid crystal projector is compensated with the generated power.

Title: Superconducting magnet
Inventor: OTA TADATOSHI
IPC: H01F6/04
Filed: 1990-11-26
Abstract: PURPOSE:To lengthen the interval of liquid helium injection, and reduce the manhour for re-injection, by winding a material member excellent in thermal conductivity like aluminum together with superconductor wire. CONSTITUTION:A pure aluminum sheet 8 is wound together with superconductor wire 9. Since the thermal conductivity of the sheet 8 is excellent, the superconductor wire 9 is cooled all over the periphery even when the surface of the liquid helium 4 descends on account of evaporation. As the result, superconducting state can be maintained when the quantity of the liquid helium decreases to some extent. In this manner, the pure aluminum sheet excellent in thermal conductivity is wound together with the superconductor wire, thereby forming a superconducting coil. Hence the superconducting state can be maintained, when the quantity of the liquid helium becomes less than the lowest level which maintains the superconducting state, so that the injection interval of liquid helium is lengthed, and a superconducting magnet can be operated for a long time.
