Latest Patents

Iriuchijima's latest patents include a head suspension and a method of manufacturing head suspension. The first patent describes a head suspension that features a conductive base plate, a piezoelectric element, and a load beam. The piezoelectric element deforms in response to an applied voltage, allowing the load beam to move relative to the base plate in a sway direction. This design includes an actuator base that is integral with the base plate, along with an auxiliary plate that supports the piezoelectric element. The head suspension is designed to be thin while ensuring conductivity between the electrode plane of the piezoelectric element and the actuator base.

The second patent also focuses on head suspension technology, incorporating a load beam and a piezoelectric actuator. In this design, the piezoelectric actuator is connected to the base part of the load beam, with the piezoelectric element attached to an opening in the actuator base. The actuator displaces the front end of the load beam in a sway direction based on the deformation of the piezoelectric element. This patent includes features to prevent contamination from nonconductive adhesive used in the assembly process.
