Title: Innovations by Yoshio Higashida: Pioneering Patent Holder from Osaka

Introduction

Yoshio Higashida is an accomplished inventor based in Osaka, Japan, recognized for his significant contributions to technology through two notable patents. His innovative ideas focus on timing recovering apparatuses and delay circuits, showcasing his expertise in signal processing.

Latest Patents

Higashida's latest patents highlight his profound understanding of complex electronic systems. The first patent describes a **timing recovering apparatus having window periods determined by period**. This device includes an equalizer designed to equalize a digital data signal subjected to interleaved NRZI (Non-Return-to-Zero Inverted) encoding. It features two comparators to compare the equalized data signal with differing reference levels, alongside phase comparator circuits to detect phase differences. Additionally, an adder sums the outputs of the phase comparators, leading to a voltage-controlled oscillator (VCO) that generates a reproduced clock signal based on the addend output. This innovation ensures that the clock signal remains unaffected by the data pattern of the digital signal.

The second patent is a **delay circuit for changeably delaying an analog signal**. It employs an npn transistor with a base connected to the input terminal, facilitating a constant current flow from its emitter to ground through a constant current source. With strategically placed resistors and capacitors, the delay circuit allows for variable delays in the analog signal, depending on the adjustments made to the constant current. This invention is crucial for applications that require precise timing adjustments in electronic communications.
