Title: Nobuo Sato: Innovator in Power Source Technology
Introduction
Nobuo Sato is a prominent inventor based in Miyagi, Japan. He has made significant contributions to the field of power source technology, holding 2 patents that showcase his innovative approach to electrical engineering. His work primarily focuses on enhancing the efficiency and functionality of power sources and antenna systems.
Latest Patents
One of Nobuo Sato's latest patents is for a current resonance type switching power source. This invention involves a switching power source that alternately activates the first and second MOS transistors, allowing a resonance current to flow to a primary winding of a transformer. This design enables an alternate current to be transmitted to the secondary side. The patent details how a gate voltage is applied to ensure that the third and fourth MOS transistors are conductive, improving the efficiency of the power source through synchronous control.
Another notable patent is for an antenna unit and portable radio terminal with a feeding circuit. This invention allows for fine antenna characteristics when the antenna is either contained or pulled out. The design ensures that when the second antenna is contained, it is electrically disconnected from the feeding circuits, allowing only the first antenna to operate. Conversely, when the second antenna is pulled out, the first antenna's electrical length is varied, optimizing performance.
