Title: Innovations of Junichi Makino
Introduction
Junichi Makino is a prominent inventor based in Katsuta, Japan. He has made significant contributions to the field of optical sensors and automotive technology, holding a total of seven patents. His work reflects a deep understanding of both theoretical and practical applications in engineering.
Latest Patents
One of his latest patents is an interference sensor and method utilizing extracted aliasing frequency. This innovative sensor passes radiation from a source through a polarizer to a loop of optical fiber, allowing radiation beams to circulate in opposite directions and interfere. The loop contains an optical phase modulator that imposes an optical modulation on the circulating beams. A converter detects the interfering and modulated beams, generating an interference signal that is processed by an analyzer. The interference in the loop is dependent on its rotation, enabling precise measurement of that rotation through analysis of the interference signal. The analysis can be conducted in either the frequency domain or the time domain, depending on the requirements of the application.
Another notable patent is a thermal type intake air flow measuring instrument. This invention features an analog circuit designed for a thermal type intake air flow sensor, which detects the quantity of air drawn into an automotive engine. The circuit is integrated as part of the input hardware of a microcomputer that controls the engine. It is optimized for high-speed operations, while adjustments and output processes are executed under the same operating system used for engine control.
