Tetsuro KAMIYOSHI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10795381
    Abstract: 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.

  • Patent number: 10767765
    Abstract: 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.

  • Patent number: 10571031
    Abstract: 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.

  • Patent number: 10273667
    Abstract: A faucet apparatus includes a rotating operation unit that rotationally operates water spouting and shutting off operations, and a flow adjustment operation and a temperature adjustment operation of hot and cold water, an acceleration sensor that detects an attitude and a rotating movement of the rotating operation unit, and a control unit. The rotating operation unit moves without striding across a horizontal plane at a time of performing a rotating operation from a first operation position to a second operation position around a predetermined rotation axis in the water spouting state. The acceleration sensor is set in a state where a rotation axis at a time of rotating within a predetermined plane in response to the flow adjustment operation and temperature adjustment operation of the hot and cold water does not coincide with a gravity direction axis.
