Title: Method for extending life of fluorescent display tube
Inventor: HAYAKAWA KATSUTOSHI
IPC: F21S2/00
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To make a fluorescent display tube usable up to the natural life without being claimed by a user by lighting all phosphor patterns only for a short time of about several minutes in an optional time such as input of a power source. SOLUTION: A display control part 22 is formed of a CPU, and automatically lights all phosphor patterns when the power source part 24 of a fluorescent display tube in ON in addition to conventional lighting control. A timer 23 measures the lighting time in this case, and notifies the lapse of a prescribed time of the display control part 22. When the prescribed time is 2 seconds, for example, lighting of all the phosphor patterns is terminated when 2 seconds passed. Since cleaning of the phosphor patterns is thus frequently executed at a short interval such as input of power source, and the contamination by gas deposited to the phosphor patterns causing a dispersion in brightness is removed, a brightness causing no user claim can be held up to the natural life.

Title: Analyzing method for dyestuff or agricultural chemicals
Inventor: HARUMI TAKAFUMI
IPC: G01N33/02
Filed: 1993-08-17
Abstract: PURPOSE:To efficiently analyze by using organic solvent as migrating medium in order to analyze dyestuff or agricultural chemicals by a free interface electrophoretic method. CONSTITUTION:When dyestuff or agricultural chemicals (herbicide, insecticide, bacteriocide, etc.) are analyzed by a free interface electrophoretic method, organic solvent is used as migrating medium. As the organic solvent, methyl alcohol, ethyl alcohol, acetonitrile, etc., is, for example, used solely or by adding with strong acid or strong base. The solvent is used to remove Kohlrausch's deterioration of peak sensitivity, degree of separation occurring by mutual action of buffer ions and sample liquid ions. In addition, since the solvent has smaller current flow rate than that of water, shape deterioration of the peak due to Joule heat and spread due to thermal diffusion are prevented to improve analyzing sensitivity.
