Title: Hitoshi Ohsato: Inventor of High-Frequency Ceramic Technology
Introduction
Hitoshi Ohsato is an inventor associated with Aichi, Japan. His work includes a patent for a high-frequency porcelain composition designed to improve ceramic performance while enabling lower-temperature sintering. He is credited with 1 patent.
Latest Patents
Ohsato’s patent, “High-Frequency Porcelain Composition, Process for Producing the Same and Planar High-Frequency Circuit,” describes adding 15% to 35% by weight of rutile-type titanium dioxide to forsterite. This addition allows the composition to be sintered at 1,200°C while retaining the crystal phases of both materials.
The resulting ceramic composition preserves the high quality factor Q·f associated with forsterite, while rutile-type titanium dioxide helps control the absolute temperature coefficient to 30 ppm/°C or less. These properties make the composition relevant to high-frequency ceramic applications and planar circuits.
Career Highlights
Ohsato’s listed company affiliations include Yasufuku Ceramics Co., Ltd. and Marusu Glaze Co., Ltd. His patent reflects work on ceramic materials and processing methods for high-frequency applications.
Collaborations
Ohsato’s listed coworkers include Tsutomu Tsunooka and Tomonori Sugiyama.
Conclusion
Hitoshi Ohsato’s patented composition combines forsterite and rutile-type titanium dioxide to support lower-temperature sintering while maintaining useful high-frequency properties.
