With a total of four patents to his name, Miyazawa's work has had a considerable impact on automotive technology.

Latest Patents

Miyazawa's latest patents include a "Hydraulic Control System with Condition Responsive Accumulator Control" and a "Hydraulic Control System for Automatic Transmission." In the first patent, during a shift operation, a time interval TT required to switch a mechanical gear ratio is detected. To align this with a reference value, the duty cycle of a linear solenoid valve SL6, which determines back pressure on an accumulator, is adjusted. This adjustment is made based on oil temperature, throttle valve opening, and shift mode of the automatic transmission to prevent shift shocks caused by variations in shift response. The second patent shares similar principles, focusing on the same mechanisms to enhance the performance of automatic transmissions.
