Japan's First Pressurized Oil Stove: Type SB

This machine is a pressurized oil stove developed by Tetsue Uchida, who was the founder of Uchida Works (now Corona Corp.). The technology that formed the basis of the company's business began after the Great Kanto Earthquake, when the company focused on the shortcomings of gasoline stoves and taught itself to develop stoves that use safe and inexpensive light oil. In 1952, the company established a fuel-vaporization technology using preheating pipes, and in the following year, it perfected a pressurized oil stove that burned with a smokeless, odorless blue flame.
As the company diversified in later years, it applied the fuel-vaporization technology it had developed for pressurized oil stoves to oil heaters.
Further research and development improved the mixing-tube design, which overcame the issue of unvaporized fuel emissions. Additionally, the mixing tube was designed for portability and was released as the “Corona Gas Oil Heater Type SB”in 1955. Because of its one-handle operation and high safety level, approximately 3,000 units were produced in the first year and 10,000 units a year later. The total production of the series doubled every year thereafter, and by 1960, Corona's oil-stove production constituted approximately 30% of the national market. The fuel-vaporization technology has been widely adopted in modern fan heaters and other oil heaters, which have revolutionized the perception of heating in Japan and contributed significantly to the improvement of people's lives.
