Title: Takayuki Handa: Innovator in Optical Communication and Fusion Technology
Introduction
Takayuki Handa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of optical communication and fusion technology. With a total of 4 patents to his name, Handa's work has had a substantial impact on modern technology.
Latest Patents
One of Handa's latest patents is a dispersion compensating device using a dispersion compensating fiber module. This device is designed to compensate for the dispersion of signal light in optical fiber communication systems. It effectively addresses the distortion of optical pulse waveforms caused by wavelength distortion. The signal light is inputted through an input port and propagates through a dispersion compensating fiber via an optical circulator. The innovative design allows the signal light to reflect off a highly reflective surface and propagate through the fiber reciprocally, enabling compensation for dispersion with half the length of conventional methods.
Another notable patent is related to the electrofusion of electrofusion joints. This invention includes an electrical heating wire embedded in the inner peripheral region of the joint, which can be fitted to the end of a plastic pipe. By supplying electrical current to the heating wire, the interface between the joint and the pipe is fusion bonded. The design features an annular groove that allows for easy determination of the completion of fusion bonding. A pin or bar-like core member extends from the center of the groove, providing a mechanism to confirm successful fusion through the observation of limited movement of a stopper member.
