Kuninori MATSUI 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).
Abstract: There is provided an actuator that can prevent a decrease in strength of a plate due to hydrolysis. The actuator is provided with a diaphragm which divides an inside of a casing into a negative pressure chamber and an atmospheric pressure chamber, a resin plate which is provided inside the negative pressure chamber to contact with the diaphragm, and an operating shaft having one side connected to the plate and the diaphragm and the other side extended outside the casing through the atmospheric pressure chamber, the operating shaft capable of being displaced in the axial direction according to the deformation of the diaphragm. The operating shaft penetrates through the diaphragm to connect to the plate inside the negative pressure chamber so that the plate is blocked from the atmospheric pressure chamber.
