Title: Yoshiaki Nishiyama: Innovator in Magnetic Materials and Power Supply Technology
Introduction
Yoshiaki Nishiyama is a notable inventor based in Hiratsuka, Japan. He has made significant contributions to the fields of magnetic materials and power supply technology. With a total of 2 patents to his name, Nishiyama's work has had a considerable impact on the industry.
Latest Patents
Nishiyama's latest patents include a magnetic material biasing method and apparatus. This invention involves an apparatus such as a transformer that comprises at least a magnetic core and a main winding. The method is characterized by the addition of an auxiliary winding to the magnetic core, which allows for the flow of a predetermined amount of demagnetizing current. This current reduces the magnetic flux caused by the main winding, preventing magnetic saturation during the increase of magnetic flux.
Another significant patent is a switching regulator with a quiescent time period. This self-excited switching type D.C. power supply is designed to produce a stabilized output signal. It includes a rectifier, a primary winding of a transformer, a switching transistor, and a resistor connected in series. The design stabilizes the switching frequency of the transistor by incorporating a quiescent time period during which the transistor is disabled.
