Latest Patents

Moriya’s listed patents address motor control and power-window safety.

- **Motor Controller and Method for Controlling Motor.** This invention describes a controller for opening and closing a vehicle-door window. A relay circuit and field-effect transistor (FET) control the motor, while a sensor detects its rotation speed. A CPU uses the sensor’s signal waveform to generate a duty signal and drive the motor.

- **Power Window Device.** This invention aims to reduce heating in the motor that raises and lowers a vehicle window. A pulse sensor detects motor rotation, and an electronic control unit (ECU) uses the signal to determine whether the window has reached its fully open or closed position. The ECU deactivates the motor when it detects a locked motor or an end position, keeping it off until specified activation conditions are met.
