Abstract: A paste-type dental material is filled from an opening portion of a cartridge into a cylindrical portion by moving the opening portion of the cylindrical portion of the cartridge along a kneading surface, on which the paste-type dental material is kneaded, with the opening portion being inclined. The piston is placed on the kneading surface with a circular end surface of the piston contacting the kneading surface. The piston is inserted into the cylindrical portion by moving the opening portion of the cylindrical portion of the cartridge closer to the piston located on the kneading surface such that a piston-side tapered surface or the piston-side curved surface of the piston is fitted into the opening portion, and thereafter moving the one of the two ends of the cylindrical portion toward the kneading surface.

Abstract: A cartridge fitting portion of a cylindrical syringe made of a resin includes an end surface opening portion, a continuous opening portion continuous with the end surface opening portion, opened in a radial direction, and extending in an extending direction, and a recess portion configured to communicate with the end surface opening portion, the continuous opening portion, and an internal passage in a cylindrical body. The recess portion includes a flange fitting recess to be fitted with a flange portion of a cartridge, and a cylindrical portion fitting recess that communicates with the flange fitting recess and is fitted with a part of the cylindrical portion. A wall portion surrounding the cylindrical portion fitting recess of the cartridge fitting portion is configured to warp into snap engagement with the part of the cylindrical portion when the part of the cylindrical portion is inserted from the continuous opening portion.

Abstract: An applicator that is less expensive than those according to the related art and in which a plunger does not easily slip out of a cylindrical syringe. A cylindrical syringe and a plunger are each molded from a resin material. A resistance structure is provided between the inner peripheral surface of the cylindrical syringe and the outer peripheral surface of a pressing portion of the plunger. The resistance structure is configured to act as resistance to movement of the pressing portion when the pressing portion is moved toward a cartridge fitting portion beyond a predetermined position and to movement of the pressing portion when the pressing portion is moved from the side of the cartridge fitting portion toward an end of the cylindrical syringe opposite to the cartridge fitting portion beyond the predetermined position.

Abstract: Provided is a method that is for producing Euglena having a high wax ester content, capable of more efficiently producing the Euglena having a high wax ester content by adding a nutrient before anaerobic fermentation to restore the efficiency of wax ester fermentation. The present invention relates to a method for producing Euglena having a high wax ester content.
