Latest Patents
One of Takayanagi's latest patents is a micro-switch device and method for manufacturing the same. This micro device is produced using semiconductor processes and is designed to be electrically connected to external systems for its operation. The device features a circuit board with an electrode pad, a lead substrate that is substantially parallel to the circuit board, and a conductive lead that connects to the electrode pad. The lead is bent away from the surface of the lead substrate, with one end adhered to the substrate and the other end remaining free.
Another notable patent is for a bimorph element, bimorph switch, mirror element, and the method for manufacturing these components. This bimorph element includes a silicon oxide layer and a high expansion coefficient layer that is formed on top of it. The high expansion coefficient layer has a thermal expansion coefficient that exceeds that of the silicon oxide layer. Additionally, a deformation preventing film covers the silicon oxide layer, preventing deformation over time. This film has a lower transmission factor for moisture and oxygen compared to the silicon oxide layer, and it can be made from silicon nitride or metallic materials.
