Summary of the patent applications from TDK CORPORATION on November 30th, 2023

TDK Corporation has recently filed several patents for various technologies. These patents cover a range of inventions, including magneto-resistive elements, magnetization rotational elements, acoustic devices, power conversion apparatuses, antenna devices, multilayer ceramic electronic devices, electronic devices with chip components, and dielectric compositions.

The magneto-resistive element patent application describes a structure consisting of two ferromagnetic layers separated by a non-magnetic layer. The non-magnetic layer has a central region and an outer circumferential region, with the latter having a greater thickness. This design aims to improve the performance of the magneto-resistive element.

The magnetization rotational element patent application focuses on a spin-orbit torque wiring and a ferromagnetic layer. Spins are injected from the spin-orbit torque wiring into the ferromagnetic layer, and the spin-orbit torque wiring includes multiple spin generation layers and insertion layers. The insertion layers have a lower electrical resistivity than the spin generation layers, enhancing the efficiency of the magnetization rotational element.

The acoustic device patent application describes two vibrating bodies with different vibration frequencies placed on a base material. The arrangement of the vibrating bodies on the base material is in the same direction, allowing for improved acoustic performance.

The power conversion apparatus patent application includes a sensor, a signal generation circuit, and a control circuit. The sensor generates a detection signal, which is processed by the signal generation circuit to generate a second detection signal. The control circuit is responsible for controlling the operation of the power conversion circuit. This design aims to improve the accuracy and efficiency of power conversion.

The antenna device patent application focuses on multiple layers and ground patterns. The antenna layer includes radiation conductors and ground pillars, and the ground patterns have three areas, with the third area connecting the first two areas. This design helps improve the performance and efficiency of the antenna device.

The multilayer ceramic electronic device patent application describes an element body with internal electrode layers and external electrodes. The external electrodes consist of two layers, with the first layer in direct contact with the element body and the second layer on top. The composition and structure of the external electrodes aim to enhance the performance and reliability of the ceramic electronic device.

The electronic device patent application focuses on a chip component, case, resin, and conductive terminal. The conductive terminal has an inner electrode portion connected to the terminal electrode of the chip component. The inner electrode portion includes a space formation portion for a conductive agent, improving the electrical connectivity of the electronic device.

The dielectric composition patents describe compositions with specific structures and phases to enhance their dielectric properties. These compositions can be used in various applications that require high dielectric constant materials.
