Patent number: 10158274Abstract: A rotary machine including a rotary shaft rotatably disposed in a casing is provided. The rotary machine includes an end plate disposed at one end side of the casing in the axial direction. The rotary machine includes a recess section formed in the end plate and recessed toward the inside of the casing. The rotary machine includes a through hole formed in the recess section and through which one end section of the rotary shaft is inserted. The rotary machine includes a shaft grounding device which is provided in the recess section. The shaft grounding device is brought into contact with the one end section of the rotary shaft which is inserted through the through hole, and eliminates a shaft voltage generated in the rotary shaft.Type: GrantFiled: April 28, 2016Date of Patent: December 18, 2018Assignee: MEIDENSHA CORPORATIONInventors: Tamotsu Sakai, Tomokazu Arigami, Hiroaki Matsuno, Satoshi Okano

Patent number: 5241080Abstract: A process for stabilizing dibenzylidenesorbitols comprising incorporating 0.05-20 pts. wt. sorbic acid and/or potassium sorbate in 100 pts. wt. dibenzylidenesorbitol represented by the following formula, ##STR1## and a stabilized dibenzylidenesorbitol composition formed thereby. The storage stability of dibenzylidenesorbitols is thus greatly improved.Type: GrantFiled: June 25, 1992Date of Patent: August 31, 1993Assignee: Mitsui Toatsu Chemicals, Inc.Inventors: Tadashi Kobayashi, Hiroaki Matsuno, Shoji Obuchi

Patent number: 4923951Abstract: An aromatic polyamide is produced by subjecting an aromatic diisocyanate and an aromatic dicarboxylic acid to polycondensation in the presence of an alkali metal compound and/or an alkaline earth metal compound as a catalyst in an aprotonic polar solvent. The aromatic polyamide can be rendered suitable for use in the production of high-tenacity fibers by charging in advance the solvent, aromatic dicarboxylic acid and catalyst in a mixing system, reducing the water content in the mixing system to at least 50 ppm and then introducing the aromatic diisocyanate to conduct the polycondensation.Type: GrantFiled: February 7, 1989Date of Patent: May 8, 1990Assignee: Mitsui Toatsu Chemicals, IncorporatedInventors: Tadashi Kobayashi, Shouji Obuchi, Hiroaki Matsuno, Mitsuo Wada, Hiroshi Takayanagi
