Latest Patents

One of Sadaaki Baba's latest patents is a current detector that features a magnetic core designed to concentrate magnetic flux near a Hall-effect sensor. This innovative device includes a Hall-effect component that detects the magnetic field generated by a current flowing through a conducting portion. The magnetic core has a first end face for concentrating the magnetic flux and a second end face that is smaller in area, positioned close to the Hall-effect sensor's detecting surface. Additionally, the device incorporates a signal processing circuit that converts the output signal from the Hall-effect sensor into a representation of the current flowing through the conducting portion.

Another notable patent is an electromagnet apparatus that reduces armature release time. This invention consists of an electromagnet coil wound on a fixed iron core, energized by direct current supplied from a full-wave rectifier. The design includes a transistor connected in series with the coil, a bias resistor across the coil, and a capacitor that absorbs inductive energy stored in the coil when the alternating current supply circuit is opened. This innovative approach significantly shortens the armature release time.
