With a total of two patents to his name, Minai's work reflects a commitment to advancing technology in practical applications.
Latest Patents
Minai's latest patents include an actuator for a valve and a material for valve seats. The actuator for a valve is designed to transfer turning power from a motor to an output shaft through an inner gearing planet gear speed reducing mechanism. This mechanism is housed in a casing and is adapted to effect speed reduction of the turning power. It utilizes the rotation of the output shaft to open and close a valve. The gear speed reduction mechanism features an eccentric body that rotates due to the transfer of turning power from the motor, an outer gear that generates a vibrating rotation, and an inner gear that meshes with the outer gear. Additionally, it includes a rotation transferring mechanism that extracts rotation from the vibrating rotation of the outer gear and transfers it to the output shaft. The mechanism is equipped with an angular positioning part that controls the rotation of the output shaft at a prescribed angle.
The second patent pertains to a composite material for valve seats. This material comprises a base material made of PTFE, along with 3 to 30% by weight of PFA based on the total amount of the base material. It also includes 5 to 30% by weight of glass fiber or 5 to 25% by weight of carbon fiber based on the total amount of the composite material. When glass fiber is used, additional components such as powdered graphite or molybdenum disulfide may be added as needed.
