Title: The Innovations of Yukio Numata
Introduction
Yukio Numata is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of electronics, particularly in the development of oscillators and receivers. With a total of 3 patents to his name, Numata's work has had a lasting impact on high-frequency apparatus.
Latest Patents
One of Numata's latest patents is an oscillator designed for use as a local oscillator in high-frequency apparatus. This invention includes a voltage-controlled oscillator, a reference oscillator, and a phase detector that detects the phase difference between the oscillation frequencies of both oscillators. The design also features a filtering mechanism to produce a DC voltage and a phase synchronizing loop that feeds back the DC output to the voltage-controlled oscillator. This oscillator can synchronize its frequency with either an odd multiple or an integer multiple of the reference oscillator's frequency, depending on the duty cycle maintained.
Another significant patent involves a method for presetting receivers of the synthesizing type. In this method, the frequency division ratio of a frequency divider in a phase-locked loop is set according to the content of an up-down counter. The process generates search and write signals to sweep the up-down counter, allowing the contents to be written sequentially into a memory device. This enables the receiver to be preset to receive signals from desired broadcasting stations.
