Title: Innovations of Satoshi Shimizu
Introduction
Satoshi Shimizu is a notable inventor based in Tochigi, Japan. He has made significant contributions to the field of piezoelectric technology, holding a total of 5 patents. His work focuses on innovative methods of manufacturing piezoelectric vibrators, which are essential components in various electronic devices.
Latest Patents
One of his latest patents is a method of manufacturing a piezoelectric vibrator. This method involves forming a gettering metal film on the surface of a piezoelectric vibrator piece and creating a frequency-adjusting weight that is separate from the gettering metal film. After placing the piezoelectric vibrator piece in a hermetic container, the container is sealed. A laser beam is then used to heat the metal film, allowing it to getter gas contained inside the hermetic container. Once the gettering process is complete, the laser beam is used again on the frequency-adjusting weight to fine-tune the vibration frequency of the piezoelectric vibrator piece.
Another significant patent is for a lead frame designed for surface mount-type piezoelectric vibrators. This lead frame features a pair of side frames with multiple positioning holes, spaced apart in the width direction. It includes at least one section bar that extends between the side frames, with first lead sections arranged at predetermined intervals along the width. The second lead sections are also arranged in a way that they are spaced apart from the first lead sections, creating a frame area between the side frames. Each second lead section has a pair of independent protruding portions positioned adjacent to one another.
