  • Patent number: 5824994
    Abstract: An electrically heated transparency which has a glass plate, a pair of bus bars provided at upper and lower sides of the glass plate and a transparent electric conductive film disposed on a surface of the glass plate so as to connect the pair of bus bars. The upper side bus bar has two upper bus bar elements. The upper bus bar elements are respectively extended to current feeding portions and have free ends at opposite positions in an upper side portion of the glass plate and near both sides of the transparent electric conductive film. The upper bus bar elements have parallel portions, in a connecting portion for connecting the upper side bus bar to the transparent electric conductive film, so as to oppose to each other with a space, and the upper bus bar elements are in contact with the transparent electric conductive film at the parallel portions.

  • Patent number: 5512752
    Abstract: A method is provided for determining the type of an unknown plastic including the steps of irradiating an unknown plastic with near-infrared rays within a prescribed measurement wavelength range to measure an absorption spectrum, calculating the differential spectrum of the unknown plastic, measuring the differential spectrum at prescribed measurement intervals, determining the class of the differential spectrum by determining whether each measurement is on a plus-side, a minus-side or any other side, comparing the class of the differential spectrum measurement at each interval with a class of a differential spectrum measurement previously determined for each of the intervals over the range for a plurality of plastics of known types, and determining the type of the unknown plastic as the plastic having the highest class agreement ratio.
