  • Patent number: 5399504
    Abstract: The quality of CuInSe.sub.2 solar cells is estimated during the manufacturing process by using a photoluminescence analysis. Emitted luminescence is measured upon irradiation of a CuInSe.sub.2 thin film with laser light, and estimation is performed on the basis of the luminous intensity. Specifically, non-defective products can be obtained by using lots in which the maximum luminous intensity in the spectral range of luminescent light of 0.8.about.0.9 eV of a sample cooled to liquid nitrogen-temperature or to liquid helium temperature is not lower than a predetermined value or is higher than the maximum luminous intensity in the spectral range of 0.9.about.1.0 eV. Further, after the manufacturing process is completed, by using this estimation, it is possible to rank the products after completion of the manufacturing process.

  • Patent number: 5395240
    Abstract: An ultrasonic handpiece wherein the entire assembled handpiece may be sterilized with an ingress of the sterilizing fluid into the interior of the handpiece. The handpiece is formed with an elongated housing sleeve and a coil unit for establishing an alternating magnetic field located therein. The housing sleeve and coil unit is assembled such that crevices are formed between the ends of the housing sleeve and coil unit, thus allowing steam, chemicals and heat to pass in and out of the interior of the handpiece for more rapid and thorough sterilizing of the handpiece. Further, the coil unit is not potted to the housing sleeve in order to allow for different thermal coefficients of expansion between materials without the buildup of undue stress.
