The present invention is a flow-rate adjustable valve for adjusting a flow rate of liquid flowing through a flow path. The flow-rate adjustable valve includes: a main valve body; a back pressure chamber; an inlet hole; an outlet hole; a pilot valve body for opening and closing an end of the outlet hole on a side of the back pressure chamber; an elongated member holding the pilot valve body; and a lifter rotatable and also movable in the axial direction of the elongated member by the rotation of the rotatable member. The lifter and the elongated member are integrally movable in the axial direction. The elongated member is connected to the lifter under a condition in which the elongated member is biased to the lifter in a one-way direction of the axial direction by a biasing-connecting member.

Flow-rate adjustable valve

The present invention is a flow-rate adjustable valve for adjusting a flow rate of liquid flowing through a flow path. The flow-rate adjustable valve includes: a rotatable member; a lifter linearly movable by a rotation of the rotatable member; a valve body linearly movable by a linear movement of the lifter; a stopper configured to restrict a movable range of the lifter in a fixed state of the stopper in which a position of the stopper is not able to be changed; and a stopper-holding member configured to hold the stopper selectively in the fixed state or in a provisional fixed state in which the position of the stopper is able to be changed.

Flow-rate adjustable valve and method of manufacturing the same

The present invention is a flow-rate adjustable valve for adjusting a flow rate of liquid flowing through a flow path. The flow-rate adjustable valve includes: a main valve body movably supported in the flow path via a diaphragm membrane; a back pressure chamber; a plurality of inlet holes communicating the upstream side of the flow path with the back pressure chamber; an outlet hole communicating a downstream side of the flow path with the back pressure chamber; and a pilot valve body for opening and closing the outlet hole, wherein moments acting on the main valve body based on the liquid flowing into the back pressure chamber through the plurality of inlet holes are canceled by each other in total, under a condition in which the pilot valve body opens the outlet hole.

A touch detection device has a sensing unit that includes a contact portion which comes into contact with an object, a vibration excitation element that vibrates the contact portion, a detection circuit that includes a drive circuit and a contact determination circuit, and an electrical wire that connects the vibration excitation element and the detection circuit, and is covered with a covering material. The vibration excitation element is covered with a potting layer made of resin through a predetermined internal space. While being inserted into the potting layer, the electrical wire has an end connected to the vibration excitation element, and an insertion portion inserted into the potting layer includes a non-covering portion formed by peeling of the covering material.
