Abstract: A traveling vehicle system, in a merging area including a merging point, until a traveling vehicle traveling on one travel route passes through the merging area, stops a traveling vehicle traveling on another travel route at a stop point before the merging point. The traveling vehicle system calculates a required time for a first traveling vehicle passing through the merging point to pass through the merging area and, when a second traveling vehicle following the first traveling vehicle and traveling on the same travel route as the first traveling vehicle outside the merging area is capable of entering the merging area within the required time, causes the second traveling vehicle to enter the merging area without decelerating the second traveling vehicle to a speed limit or less enabling stopping at the stop point.

Abstract: A tube holder includes at least a set of clamping members having circular arc-shaped clamping concave portions, a spindle pivotably supporting end portions on one side along the circular arcs of the clamping members in a state where the clamping concave portions facing curvature center sides of the respective circular arcs face each other, and a biasing member pivoting and biasing end portions of the other side along the circular arc of the clamping member in a direction of mutual approaching.

Abstract: A ventilation device installed on an infant incubator having a chamber of an infant, including: an exhaust part including an exhaust connect port connected to the chamber and an exhaust port communicated with the exhaust connect port; an air-supply part including an air-supply connect port connected to the chamber and an intake port of external air communicated with the air-supply connect port; at least one of an exhaust blower and an air-supply blower: the exhaust blower is provided at the exhaust part and generates an air stream flowing from the exhaust connect port toward the exhaust port, and the air-supply blower is provided at the air-supply part and generates an external-air stream flowing from the intake port of the external air toward the air-supply connect port: the air is exhausted from the chamber through the exhaust part, and the external air is supplied into the chamber through the air-supply part.
