Latest Patents

One of Hosoda's latest patents is for a semiconductor acceleration sensor. This innovative sensor features a small difference in acceleration detection sensitivity among the X, Y, and Z axes, along with high detection sensitivity. The design includes a mass portion at its center, surrounded by a support frame and connected by multiple flexible arms. These flexible arms are designed with wider portions at both ends and a narrower section in between. Piezo resistors are strategically placed within the top surface region of the wider portions, and through holes connect metal wires to the piezo resistors. The symmetry of the flexible arms enhances the sensor's performance.

Another notable patent is for a floating magnetic head device and its securing method. This device includes a slider attached to a holding member, with a recessed groove formed near the trailing edge of the slider. The portion of the holding member closer to the leading edge is attached to the back of the slider. To secure the magnetic head, a coating material, such as IPA, is applied to the trailing edge of the slider before it is adhered to the holding member. After the adhesive sets, the IPA is cleaned away to create a clearance.
