Latest Patents

One of Ono's latest patents is a liquid material supply system. This system includes a plunger pump, a flow regulating valve, an air-operated valve, a spring-type accumulator, and a dispenser. The plunger pump is connected to the flow regulating valve by a primary supply line, while the flow regulating valve is linked to the dispenser through a secondary supply line. An on-off valve is also connected to the secondary supply line. The accumulator is strategically placed in the secondary supply line between the on-off valve and the dispenser. A pressure sensor detects the pressure at the inlet port of the dispenser, which is crucial for controlling the operation of the air-operated valve via an electromagnetic valve. The second chamber of the accumulator can store part of the liquid material supplied through the secondary supply line, and its volume varies based on the balance between the force of the accumulator spring and the pressure in the secondary supply line, effectively reducing pressure fluctuations.

Another significant patent by Ono is for a uniaxial eccentric screw pump featuring a flexible plastic shaft. In this design, a boss is integrally formed on one end of the rotor, and one end of a flexible shaft is inserted into this boss and bonded with the rotor using adhesive. The flexible shaft is partially made from a rod-like member extruded from PEEK (polyetheretherketone), a type of engineering plastic. Additionally, a metal rod is provided in the middle of the flexible shaft or a metal sleeve is mounted over its outer circumference, enhancing the pump's functionality.
