Abstract: PROBLEM TO BE SOLVED: To provide a screen which can improve the contrast of videos by making a surface to be displayed with the videos visible substantially gray or black. SOLUTION: The screen 10 has a mat layer 12 which is disposed at a sheet 11 and is used to diffuse and reflect light and a contrast regulating layer 15 which consists of three kinds of colored beads 15A to 15C fastened to the mat layer 12 by an adhesive layer 14. The colored beads 15A to 15C are respectively colored to any among three kinds of chromatic colors (cyan color, magenta color and yellow color) are respectively disposed to scatter on the surface of the mat layer 12 at such quantities at which these chromatic colors are mingled with each other and appear achromatic approximate to gray color when an observer observes the screen 10 from remote in such a manner that the white light is made incident as external light thereon.

Abstract: PROBLEM TO BE SOLVED: To form an inorganic thin film on a base material formed of organic substance, with excellent adhesion by applying a voltage to the base material in plasma of ionized inorganic substance to form an ion implanted layer with inorganic ion implanted, on the surface of the base material. SOLUTION: Base material 2 formed of organic substance is fitted to a holder 5 in a vacuum container 3, and the interior of the vacuum container 3 is evacuated to create a high vacuum. Inorganic ion is generated by an ion generating device 6 and led into the vacuum container 3. In the state of the base material 2 being disposed in plasma containing inorganic ion, pulse-like voltage generated by a pulse power source 8 is applied as bias voltage to the base material 2. Bias voltage is adjusted, and inorganic ion in plasma is implanted in the base material 2 to form an ion implanted layer on the surface of the base material 2. Inorganic ion in plasma is then accumulated on the ion implanted layer to form an inorganic thin film with excellent adhesion. Oxygen and/or nitrogen may be led into plasma and implanted as an oxide and/or a nitride.

Abstract: PROBLEM TO BE SOLVED: To positively detect a specimen with a simple configuration allowing the specimen to contact the outer surface side of an optical surface so that it can simultaneously contact a set of transparent thin-film electrodes and applying incidence light to the optical surface at an incidence angle so that total reflection conditions are met. SOLUTION: An application beam L1 of an LED 3 is applied to a total reflection surface 12A of a right-angled prism 12 so that total reflection conditions are met. At this time, the finger tip of the specimen with a fingerprint to be detected is allowed to contact the outer side of the total reflection surface 12A. As a result, application light L20 being reflected on the total reflection surface 12A is emitted from an emission surface 12C and an image on the total reflection surface 12A is formed at a focal point of the detection part of a CCD 6. It is photoelectrically converted to an electrical signal S1 by the CCD 6, and an image- processing part 17 creates a binary image of a fingerprint according to the intensity distribution of the reflection light L20 based on the electrical signal S1. Further, a fingerprint that is detected by the binary image is compared with the specific fingerprint pattern that has already been registered. On the other hand, a set of transparent thin-film electrodes 13 are provided at the outer-surface side of the total reflection surface 12A and an organism detection device judges whether one that contacts it is part of an organism or not according to the change in permitivity.
