Abstract: A storage battery module includes a storage battery group, first and second end plates, a coupling band, and a pressing device. The storage battery group includes storage batteries stacked in a stacking direction and has a first end and a second end opposite to the first end in the stacking direction. The first and second end plates are provided at the first and second ends, respectively. The coupling band couples the first and second end plates to each other. The pressing device includes pin-shaped members pressing the storage batteries in a pressing direction and a fixing portion fixing the pin-shaped members to the coupling band.

Abstract: A wiring protective cover structure for an electric drive vehicle is provided that can be used to cool a battery while effectively blocking noise that is generated from wiring for connecting an electric power converter and the battery disposed on a floor panel.

Abstract: A pipe coupling comprises a socket having a ball valve in which a through bore having one end that allows insertion of a plug is formed and a casing supporting the ball valve for rocking motion. The casing has a slot extending from its flank to the top. The slot has a flank opening and a top opening. The flank opening is wider than the top opening. A lock element is located for movement in the through bore of the ball valve. When the one end of the through bore of the ball valve is aligned with the flank opening, the lock element advances into the flank opening, thereby preventing the ball valve from rocking. When the lock element is pushed into the through bore of the ball valve by the plug, it is disengaged from the flank opening, whereupon the ball valve is allowed to rock.

Abstract: Disclosed is a Coriolis flowmeter which is capable of detecting a mass flow and a density of fluid with an increased stability by resonantly oscillating a double tube portion consisting of an inner flow tube allowing fluid to flow therein and a coaxially disposed thereon counterbalance tube provided with a weight for equalizing the lateral natural frequency of the counterbalance tube with that of the flow tube. The Coriolis flowmeter has supporting metal means for supporting the both ends of the flow tube in such a way that the both ends of the flow tube is restricted in radial directions and axially movable in respective connecting flange; the inner flow tube has extending ends enlarged in diameter and supported in the respective connecting flanges of the outer housing.
