Filed: 1990-08-29
Abstract: PURPOSE:To quickly stabilize the lamp temperature and maintain high stability by detecting the temperature of a radiating fin with a temperature sensor, processing the detection signal, and driving a Peltier element in response to its result. CONSTITUTION:The light emitted from a D2(heavy hydrogen) lamp 1 is divided into rays with a single wavelength by a spectroscope 3, and the rays pass a measured sample in a cell 4 and are detected by a light receiving element 5.

Inventor: SAKAI SHIGETAKA
IPC: D21H21/40
Filed: 1995-08-12
Abstract: PROBLEM TO BE SOLVED: To carry out forgery preventive treatment as a part of a conventional paper making process without requiring a specific post-treating process by a method wherein an inner layer of paper is impregnated with fluorescent pigment or the like mixed in water soluble resin. SOLUTION: A rotary screen 6 is revolved in synchronism with a traveling speed of a wet blanket 5, and revolved with a motor via a chain. The rotary screen 6 is of a cylindrical shape wherein fine meshes are provided on an outer periphery. A pattern of a specific shape, a character, a symbol, etc., are formed on the meshes. Fluorescent pigment flows out of that part. A pattern of the fluorescent pigment is formed at specific intervals on wet paper 8 by rotation of the rotary screen 6. The fluorescent pigment is made by mixing fluorescent pigment as main constituent in water-soluble resin, which can emit fluorescence by irradiation with ultraviolet rays. The fluorescent pigment is impregnated one by permeating an inside of the paper. Such a treatment can be carried out only by a paper maker, and forgery of the paper is very difficult.
