  • Optical recording medium
    Patent number: 5776656
    Abstract: The invention provides an optical recording medium comprising at least two recording layers containing a dye. At least two layers of the recording layers have different optical constants, and at least one among these recording layers having different optical constants contains a dye which forms a thin film having an absorption spectrum whose half-value width is up to 170 nm. This construction permits the medium to be written and read in a conventional wavelength range of about 780 nm and a shorter wavelength range of about 630-680 nm.

  • Humidity sensor and method for making
    Patent number: 5546802
    Abstract: A humidity sensor includes a pair of opposed electrodes disposed on an insulating substrate and defining a gap therebetween and a humidity sensitive thin film covering the gap. This thin film is formed by coating a polymer of specific structure having an ethylenically unsaturated reactive group and exposing the coating to ultraviolet radiation for crosslinking. The sensor is fully water resistant and produces accurate outputs over a wide humidity range and thus can detect and determine moisture in the surrounding atmosphere.
