Latest Patents
Kushida's latest patents include groundbreaking technology for electronic watches. One notable invention features an electronic timepiece equipped with a stepping motor and a drive circuit. This design allows for precise control of the rotor's movement through electrical drive pulses. The control circuit is designed to apply alternating polarity electrical drive pulses, ensuring that the stepping motor rotor rotates in the correct direction. Additionally, the invention includes resetting circuitry that corrects the time kept by the watch, preventing any loss of time after a reset. Another patent introduces a non-operation detecting circuit that identifies when the stepping motor is not functioning. This circuit generates a non-operation signal, which is counted and stored for later use. When the motor resumes operation, a quick feed control circuit advances the motor to display the corrected time, even after external conditions have rendered it inoperative.
