Latest Patents

Sasakura's latest patents include a "Throttle Full-Closure Detecting Apparatus" and an "Ignition Control System for Internal Combustion Engines." The throttle full-closure detecting apparatus is designed to determine the full-closure state of a throttle valve by utilizing the minimum value of a throttle sensor voltage. This innovation compensates for changes in temperature, ensuring accurate readings. The apparatus employs a timer routine that involves AD-converting the throttle sensor output and storing it in RAM for comparison with a pre-set full-closure angle.

The ignition control system for internal combustion engines features a reference angle sensor that detects the engine's rotational speed and identifies a point near the top dead center. This system generates a reference angle signal and computes the ignition timing and energization time of the ignition coil based on signals from both the reference angle sensor and an angle sensor.
