Abstract: A motion guide apparatus which prevents a retainer from falling-off. A motion guide apparatus includes a track member having a rolling element rolling portion; a movable member having a loaded rolling element rolling portion facing the rolling element rolling portion of the track member; a return path; and a turn-around path connected to a loaded path and the return path; a plurality of rolling elements placed in the loaded path, the return path, and the turn-around path; and a retainer configured to hold at least one of the plurality of rolling elements. Grooves into which an end of the retainer in a width direction thereof enters are formed in the loaded path, the return path, and the turn-around path. A width of the grooves in at least a part of the turn-around path and/or in the return path is greater than a width of the groove in the loaded path.

Abstract: It is an object of the present invention to provide a therapeutic agent for RNA viral infection, comprising a novel combination of a pyrazine derivative and a specific compound, which exhibits effects against an RNA virus, and also to provide a therapeutic agent for RNA viral infection, comprising a combination of a pyrazine derivative and a specific compound, which is capable of simultaneously reinforcing antiviral activities against a plurality of RNA viruses. According to the present invention, provided is a therapeutic agent for RNA viral infection, which comprises a combination of a pyrazine derivative or a salt thereof and a compound which increases the amount of a pyrazine derivative ribose triphosphate in a cell.

Abstract: Provided is a double-row roller bearing, which is capable of suppressing a frictional force from being increased due to variation in force of press contact between outer and inner rings and rollers to enable smoother relative rotational movement between the outer ring and the inner ring, and is also suitable for downsizing and higher in versatility.

Abstract: Provided is a double-row roller bearing, which is capable of suppressing a frictional force from being increased due to variation in force of press contact between outer and inner rings and rollers to enable smoother relative rotational movement between the outer ring and the inner ring, and is also suitable for downsizing and higher in versatility. The double-row roller bearing includes: the inner ring; the outer ring; and the plurality of rollers arranged between the inner ring and the outer ring. On an inner peripheral surface of the outer ring, a pair of lateral protruding portions continuous along a circumferential direction are formed at an interval in a direction of a rotation axis. On an outer peripheral surface of the inner ring, an intermediate protruding portion continuous along the circumferential direction is formed so as to be positioned between the lateral protruding portions.

Abstract: An apparatus for transmitting torque from a driving unit to a driven unit, comprising the first unit, the second unit and a plurality of torque transmission units. The first unit serves as the driving unit, which is rotatable around a central axis thereof. The second unit serving as the driven unit, which is rotatable around a central axis thereof. The torque transmission units transmits torque from the first unit to the second unit. The torque transmission units enables a relative displacement between the first unit and the second unit in a direction perpendicular to the central axis of the first unit in a state in which the central axes of the first and second units are kept in parallel with each other. The torque transmission units are placed at different positions from the central axis of the first unit.
