Patent JP-H02226647-A (JP)
Title: Electrode for discharge lamp
Inventor: ONISHI YASUO
IPC: H01J61/073
Filed: 1989-02-27
Abstract: PURPOSE:To obtain a discharge lamp cathode with stable arch by mixing a W and an alkaline earth metal oxide powders in a specific weight ratio, sintering the powder mixture, forming the tip part into a corn-like shape and a reverse conical shape caved part in the tip, and forming a fine hole in the caved part. CONSTITUTION:In an electrode main body comprised of a connection part, a base part, and a cylindrical part, a sintered body 2 is inserted in the cylinder part to form a cathode. The corn-like tip 2a of the sintered body 2 has the summit angle theta and a fine hole 10 is formed in the bottom of the caved part 9. The sintered body 2 is prepared by mixing a high melting point metal powder such as W and an alkaline earth metal oxide powder in a ratio e.g. 100:(10-20) weight ratio and sintering the mixture. Ba diffused from the inside of the fine hole is spread in the periphery of the tip 11. As a result, in the case of low electric current, an arch is maintained within the periphery 11 of the tip but in the case electric current becomes high, an arch is maintained just like covering the periphery 11 of the tip. Owing to this, even when the current is increased, drastic increase of current density is prevented. A cathode with stable arch, low blacking of a bulb, and little sintering loss of the tip is thus obtained.

Title: Separating apparatus for magnetic powdery particle
Inventor: KOUNO YASUMASA
IPC: B03C1/23
Filed: 1979-04-10
Abstract: PURPOSE: To separate and remove magnetic powdery particles, especially radioactive cloud within a fluid effectively by a method wherein, in a cooling water or the like of a nuclear reactor plant, a magnet is provided on a periphery of a fluid- path pipings and an advancing magnetic field generating apparatus is arranged to a downstream branched pipe portions.  
     CONSTITUTION: A primary or a secondary cooling water of a nuclear reactor is circulated through a bypass pipe 2 by closing a valve 4 and opening a valve 5. An electromagnet 7, a magnetic field generating apparatus and a DC magnet are magnetically excited by passing electric current. The cloud powdery particles 12 floated within a cooling water are magnetically adsorbed to a DC electromagnet 7 and separated to a separating pipe 3 by a magnetic field flow 9 generated by a magnetic field generating apparatus 8. Because a terminal end of a separating pipe is in a condition closed by a housing container 11, a cooling water is flowed through a bypass pipe 2 and flowed together to a main stream. The separated cloud powdery particles 12 are dropped and precipitated to own weight and collected by an electromagnet 10 magnetically and certainly and stored in a housing container 11.

Title: Printeing blanket
Inventor: TOMONO SEIJI
IPC: B41N10/00
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To suppress a permanent set and to satisfactorily print for a long term by vulcanization molding a rubber composition containing inorganic hollow infinitesimal balls, and comminuting shells of the balls by pressurizing to form a compressive layer. SOLUTION: Inorganic hollow infinitesimal balls have remarkably high melting temperature and pressure resistant strengths of shells. Thus, in the case of vulcanization molding a compressive layer, the balls are not damaged or not warped in shapes. If the shells of the balls are comminuted by applying a pressure to the compressive layer after the vulcanization molding, elasticity can be given to air gaps, and the compressive layer having sufficient compression characteristics can be obtained. Accordingly, according to this printing blanket, the compressive layer having air gaps of a substantially true spherical state can be formed. As a result, a permanent set can be sufficiently suppressed, and the blanket for satisfactorily printing for a long period can be obtained.

Title: Preparation of 6-methyluracil
Inventor: SAIJIYOU SHIGEYA
IPC: C07C275/16
Filed: 1980-04-02
Abstract: PURPOSE: To obtain the titled compound in high yield and in high purity, by heating a lower alkyl ester of acetoactic acid and urea in a low-boiling hydrocarbon, removing water distilling with the solvent out of the system, condensing the compounds quickly through hydration, followed by heating the condensed compound in an alkali and neutralization.  
     CONSTITUTION: In condensing a lower alkyl ester of acetoacetic acid with urea to give β-uraminocrotonic ester, the compound are heated and reacted in a low-boiling hydrocarbon (e.g., n-hpexane, n-heptane, etc.), and the reaction is carried out while water distilling together with the solvent being removed out of the system. Caustic alkali is added to the reaction solution, which is neutralized, to prepare 6-methyluracil. The condensation reaction is done in the presence of an acidic catalyst, e.g., conc. hydrochloric acid, etc., so that the reaction time can be shortened. The desired compound is obtained from the raw materials in high yield not less than 90% based on theoretical yield. Since the solvent can be recycled in use, its amount is small.  
     USE: A plant growth regulator, an intermediate for drugs.
