Abstract: The invention provides a process for producing coenzyme Q.sub.10 by cultivating a novel microorganism JY-155 which belongs to the genus Trichosporon (FERM-P4650, ATCC 20566) which we discovered, in a culture medium containing sulfite waste liquor as the carbon source. The microbial cells form and accumulate coenzyme Q.sub.10. These cells are then recovered from the culture and processed to obtain the coenzyme Q.sub.10 as a compound or to obtain it in usable form while still associated with at least some of the cell material.

Abstract: A heat-sensitive recording paper containing in its color-developing layer calcined clay or calcined aluminum oxide provides an excellent recording aptitude for a facsimile equipment or thermal printer without producing residues deposition, sticking, bleeding or smearing in recording or printing.

Abstract: A liquid container having a container proper, a lid portion and bottom portion made of paperboard. Small pieces which protrude outwardly are disposed at the outer edges of inner bottom sheets. When the inner bottom sheets are bent along V-shaped fold lines, opening parts of the paperboard material at the small piece parts are held between tip pieces of outer bottom sheets in such a manner that the bent parts of the small pieces lie at the center of the bottom portion of the container. The opening parts are not exposed to the interior of the container. Therefore, the fear of contact of the opening parts with the content is completely eliminated, and the container can be utilized for a long period of time.

Abstract: Recording paper for use in, for example, an electrostatic recording system, comprising an electrically conductive base layer, a photoconductive or dielectric recording layer disposed on one surface of the base layer, and a heat-sensitive bonding layer disposed on the other surface of the base layer. The bonding layer is non-tacky at normal temperature, and it develops tackiness when heated after a recording has been made on the recording paper.

Abstract: A process for the preparation of a pulp, involving the steps of mechanically milling a fibrous vegetable material at an elevated temperature, delignifying the milled material by reaction with a chlorine-containing compound and ammonia or ammonium hydroxide, and recovering the chlorine-containing compound from the waste liquor in the form of hydrochloric acid.

Abstract: The micro-capsules are formed by providing the coating of capsulating agents comprising acetate sulfate of polyglycosides on the core substances. Aqueous solutions of the salt of cellulose acetate sulfate, starch acetate sulfate or dextran acetate sulfate are used as the said acetate sulfate of polyglycosides and the oily substances such as alkyl biphenyl, liquid paraffin, fat and higher alcohol, and pulverulent substances such as active carbon and yeast are used as the core substances. According to the method of present invention, the core substances are added to aqueous solutions of the said polyglycosides to be emulsified and dispersed therein, and then aqueous solutions of polycations are added there to cause insoluble complex comprising the said polyglycosides and polycations, and as resulting the core substances are coated by insoluble complex.
