Title: Production of heterocyclic ring-containing thiols
Inventor: DAIKYO SHIGERU
IPC: C07D521/00
Filed: 1988-12-28
Abstract: PURPOSE:To readily obtain the subject compounds useful as a raw material for medicines, other industrial products, etc., in high yield and purity in one pot, by reacting a heterocyclic ring-containing sulfonic acid with triphenylphosphine and iodine. CONSTITUTION:A heterocyclic ring-containing compound expressed by the formula A.SO3R (A is heterocyclic ring having aromaticity; R is H, alkali metal or alkyl) is reacted with triphenylphosphine and iodine to provide heterocyclic ring-containing thiols expressed by the formula A.SH. The reaction is preferably carried out in an organic solvent, such as benzene or toluene, at ambient temperature-in a heated state. If an alkali metal salt of a heterocyclic ring- containing sulfonic acid, etc., is selected as a substrate, a very small amount of water is added after the reaction and the reaction mixture is then heated for a while to quantitatively afford the aimed compounds.

Title: Polishing method using fluid abrasive mixed with subliminate material
Inventor: SUZUKI MOTOYUKI
IPC: B24B31/116
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To realize abrasives for preventing overheat of the abrasives. SOLUTION: Granular materials 26 to be subliminated at the temperature of abrasives during polishing are mixed in fluid abrasives besides abrasive grains 22. By using the abrasives, when the temperature of the abrasive grain rises to some extent during polishing, subliminate materials 26 contained in the abrasives are subliminated. In sublimination, since heat is absorbed from the abrasives, the abrasives are effectively cooled, and a base material can be prevented from being softened.

Title: Electron gun for color picture tube
Inventor: MURAI RYUICHI
IPC: H01J29/48
Filed: 1987-12-30
Abstract: PURPOSE:To design a high resolution and high reliability by disposing a 3rd electrode around a 2nd electrode of an electron gun, having a 1st electrode and the 2nd electrode, for a color picture tube. CONSTITUTION:An electron lens for focusing electron beams 111R, 111G, and 111B on the screen surface of a color picture tube is constituted with a 1st electrode 127 of a low potential and a 2nd electrode 128 of a high potential. A 3rd electrode 1 of a potential lower than that of the 2nd electrode is disposed around the 2nd electrode 128. The electron beams 111R, 111G and 111B passing near the 3rd electrode 1 are bent due to deflection electric field formed with the 3rd electrode 1 and the 2nd electrode 128 and in the end the multiplicity of electron beams 111R, 111G and 111B converge near the surface of a screen. As a result, beam passage holes 137R, 137G, 137B, 138R, 138G, 138B need not be displaced and therefore the beam passage holes can be enlarged to the limit of manufacturing electrodes. This enables to obtain an electron gun of a high resolution and high reliability and of much practical advantage.

IPC: G01C21/00
Filed: 1993-12-27
Abstract: PURPOSE:To provide route information optimum for a vehicle travel condition by evaluating a route obtained through an on-vehicle communication means and making judgement about the appropriateness of the route. CONSTITUTION:Destination data and a calculation request signal are inputted at a process 4 and when a vehicle enters the service area of a beacon on a road during a travel, a destination and the like transmission section 17 sends destination coordinates to the beacon via a process 7. Also, the beacon sends back a link train or the like leading to a terminal link. A controller 16, then, makes judgement about whether route information from the beacon or route calculated on a vehicle should be adopted. In other words, a rectilinear distance D between a receiving position and a destination is calculated, and when the distance D is shorter than the prescribed distance, a receiving route is judged not to be appropriate. When a previously obtained optimum route exists, judgement is made as to whether the vehicle is traveling along the route. When the vehicle travels along other routes, a route between a current position and the destination is calculated for use as an optimum route. Furthermore, When the distance D is longer and the previously obtained optimum route includes a certain ratio or more of the receiving route, this route is used as an optimum route. If not included, guidance is continued following the previously obtained optimum route.
