Latest Patents

One of Serizawa's latest patents is a method of electrically connecting a magnetic head, a magnetic head body, and a magnetic disc apparatus. This innovative magnetic head assembly includes a magnetic head with a terminal made of a conductive film and a supporting spring. The supporting spring features interconnecting patterns on its top and a projective electrode. The terminal of the magnetic head is connected to the projective electrode of the supporting spring through a solderless, direct contact connection. This design stabilizes the position of the magnetic head assembly and improves the relative speed variation between the magnetic head element and the magnetic disk, thereby enhancing the reliability of the magnetic disk apparatus.

Another significant patent is for a semiconductor device with reinforcement. In this design, tape carrier type semiconductor modules are mounted in holes or depressions enclosed by a frame. At least one flexible circuit is stacked as needed, and the semiconductor modules are electrically connected to electrodes formed on the frame. By mounting chip parts such as capacitors on the frame and/or flexible circuit, the mounting area of the semiconductor device can be reduced while hyperfunctioning its performance. Stacking multiple semiconductor devices with reinforcement yields even more satisfactory effects.
