Title: Driver device for electromagnetic force exhaust valve
Inventor: KAWAMURA HIDEO
IPC: F16K31/06
Filed: 1989-07-13
Abstract: PURPOSE:To supply a large current to an electric magnet for driving an exhaust valve in the direction of opening and generate a drive force which confronts the internal pressure of combustion chamber at the time of valve opening, by energizing the electric magnet with the electric charges on a capacitor. CONSTITUTION:When the crank angle sensed by a rotation sensor 7 attains the opening timing for an exhaust valve 1 set previously, a capacitor 52 in charge condition is shut off from a power supply 5 in conformity to an opening/ closing signal given by a control unit 6 and also a closed circuitry is formed with No.2 coil 32 and a normally closed switch 53, so that a large current is fed to the No.2 coil 32 from the capacitor 52, and a downward oriented large-density mag. flux is generated in an upper fixed mag. pole 31. To No.1 coil 23, by contrast, a large current is fed from another capacitor 56 in the direction of generating an upward oriented mag. flux in a magnetism passage 2. Thereby a strong repulsive force acts between the top face of the magnetism passage 2 and the upper fixed mag. pole 31, and the magnetism passage 2 and exhaust valve 1 move quickly downward, i.e. in the direction of opening.

Title: Reagent for forming fluorescent derivative
Inventor: TAKAHASHI HIROSHI
IPC: C07C67/00
Filed: 1987-07-21
Abstract: PURPOSE:To obtain the title reagent which reacts rapidly with a primary amine to give a fluorescent derivative capable of maintaining stable fluorescence intensity for a long time, by using as its constituent 2,3,6,7-tetracyano-1,4,5,8- tetraazanaphthalene. CONSTITUTION:2,3,6,7-Tetracyano-1,4,5,8-tetraazanaphthalene (referred to as TCNTAN hereinafter) is used as a reagent for forming a fluorescent derivative from a primary amine (e.g., methylamine or glycine). A fluorescent derivative can be rapidly formed from a primary amine by separately dissolving TCNTAN and a primary amine in an organic solvent or water, and mixing the two solutions at room temperature. The fluorescent derivative thus formed can maintain stable fluorescence intensity for a long time. The use of TCNTAN enables the quantitative analysis of a primary amine of long retention time by the pre-column labeling. It is also suitable for quantitative analysis by post- column labeling because of the rapid reaction.
