Latest Patents

Nishiura's latest patents include a "Stepping Motor Driving Apparatus Having Small Time Constant Regenerative." This invention involves a system for driving a stepping motor in a micro-step manner using a PWM control signal. The apparatus features a sense resistor for generating a sense voltage and operates to allow a driving current to flow through the stepping motor when the PWM control signal is activated. Additionally, a regenerative current path is included, which allows a regenerative current to flow when the PWM control signal is not activated. The resistance of the regenerative current path is designed to be larger than that of the driving current path.

Another significant patent is the "Shift Register Circuit." This circuit includes a logical operator added to the output terminal of a latch portion. It performs logical operations on the input and output signals of the latch, outputting the result as a bit signal. The design allows for a shifting speed that is twice as fast as conventional shift register circuits. The configuration also enables the avoidance of simultaneous intermediate values between high and low levels in neighboring bit sections.
