Title: Luminous stairway
Inventor: SATO NOBUNARI
IPC: E04F11/00
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To keep a stairway bright around the feet and hands of a person for some time after a light source is turned off and to allow the person to evacuate or transit by applying a luminous paint to the whole or part of the stairway and handrails attached to it. SOLUTION: A luminous paint is applied to the whole of a stairway 1 or to part of it such as risers 3 and treads 2 or handrails 4, if attached. The luminous paint aids an emergency lamp in an emergency when a light source is lost at the time of a disaster, the whole stairway is kept bright even when the emergency lamp does not exist or is not lighted, and a passage can be kept somewhat bright to an outlet for a safe escape. The luminous paint is merely applied to the stairway 1, no maintenance cost is particularly required, and this method can be easily introduced for not only a building and the stairway but also a general home at a far less cost than the installation, maintenance and control cost of the emergency power source.

Title: Reflected electron detector
Inventor: SAITOU MINORU
IPC: G01N23/225
Filed: 1979-09-28
Abstract: PURPOSE:To improve the sensitivity of detection of an electron and moderate abnormal contrast of an image, by such a simple constitution that a reflecting plate is arranged at a face-to-face position to a scintillator. CONSTITUTION:A reflected electron 6 emitted from a sample 5 is incident upon a scintillator 3 to allow it to emit light. A reflecting plate 7 is made by heavy metal, for instance, gold hard to be oxidated, tilted in such a manner that the reflected electron 6 from the sample 5, when reflected from the reflecting plate 7, is incident upon the scintillator 3 and arranged in a sideward position between an objecte lens 2 and the sample 5. Because of the reflected electron 6 reflected by the reflecting plate 7 and incident upon the scintillator 3, the quantity of emitted light of the scintillator 3 is increased, and a reflected electron image of the sample can be detected in high sensitivity. While the simultaneous detection of the reflected electron reflected in two directions from the sample 5 causes the reflected electron image of the sample to produce a suitable brightness with a clear contrast.
