Abstract: An embedded body including, at one end portion of a coaxial cable, one side antenna unit and an IC tag that is passive and connected to the one side antenna unit, and another side antenna unit at the other end portion of the coaxial cable is embedded in a conveyor belt. The one side antenna unit and the IC tag, and the other side antenna unit disposed with an interval in a width direction and the coaxial cable is embedded extending in the width direction.

Abstract: Provided is a pneumatic tire. Center blocks in a center region of a tread section are arrayed to form a pair between which are interposed inclined grooves inclined with respect to a circumferential direction. The center blocks straddle an equator from one side to the other. Notches composed of a first and second walls connected in a V shape are in treads in each center block. The first walls extend at an angle within ±20° with respect to the circumferential direction. The second walls extend at an angle of ±10° with respect to a width direction. Inclined grooves are each constituted by a see-through portion and an expanded portion having a larger groove width than the see-through portion. A width of a see-through region that can extend without intersecting an extension line of the see-through portion is made to be equal to or greater than 30% of a tread width.

Abstract: An aircraft water supply system supplies water to a water discharge port in an aircraft. A cold water flow path supplies cold water to the water discharge port. A hot water flow path supplies hot water to the water discharge port. A first control valve adjusts the flow rate of cold water flowing through the cold water flow path. A second control valve adjusts the flow rate of hot water flowing through the hot water flow path. A temperature sensor detects the water temperature at any point up to the water discharge port. A flow control unit controls the opening/closing state of the first control valve and the second control valve based on the water temperature detected by the temperature sensor.
