With a total of 3 patents to his name, Otsuka's work has had a lasting impact on vehicle safety and performance.
Latest Patents
One of Otsuka's latest patents is a method for forming a corrosion-resistant coating on a disc brake. This innovation involves coating a rotor of a disc brake with a nickel coating that contains ceramic particles in a dispersed state. The coating has a thickness of not less than 2 micrometers, which improves corrosion resistance while minimizing torque fluctuation during braking. The nickel coating is formed through composite plating, where nickel and ceramic particles are simultaneously electrodeposited on the rotor's surface. An annular jig is used to ensure a uniform coating thickness.
Another significant patent is for a hydraulic anti-skid device. This device features valving that establishes a first normal pressure transmission path between the master cylinder and the wheel brake cylinders. This path allows for anti-skid pressure reduction to prevent wheel lock-up. In the event of a malfunction, a second fail-safe pressure transmission path is established. The valving includes a valve that is held open by abutment with a spool formed with a bore. This innovative design enhances vehicle safety by ensuring reliable braking performance.
