Title: Shigeru Obara: Innovator in Crystal Resonator Technology

Introduction

Shigeru Obara is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of crystal resonators, holding a total of 9 patents. His work has advanced the technology used in various electronic devices, showcasing his expertise and innovative spirit.

Latest Patents

One of Obara's latest patents involves a crystal resonator that includes a flat plate-shaped crystal element and excitation electrodes. The crystal element features principal surfaces that are parallel to an X'-axis and a Z'-axis. The X'-axis is designed to rotate within a range of 15 to 25 degrees around a Z-axis, while the Z'-axis rotates within a range of 33 to 35 degrees around the X'-axis. The excitation electrodes are strategically formed on the principal surfaces, with a first region exhibiting a circular outer shape and a second region that is thinner and has an elliptical outer shape. This innovative design enhances the performance of the crystal resonator.

Another patent by Obara describes a crystal resonator that includes a crystal element and excitation electrodes. Similar to the previous design, the crystal element has principal surfaces parallel to an X'-axis and a Z'-axis. The X'-axis rotates within a range of 15 to 25 degrees around the Z-axis, while the Z'-axis rotates within a range of 33 to 35 degrees around the X'-axis. The excitation electrodes are formed on the principal surfaces, featuring elliptical mesa portions that project from the outer peripheries. This design further optimizes the functionality of the crystal resonator.
