Title: Takeo Seki: Innovator in Piezoelectric Technology
Introduction
Takeo Seki is a notable inventor based in Kokubunji, Japan, recognized for his contributions to piezoelectric technology. With a total of three patents to his name, Seki has made significant advancements in the field of electronic devices, particularly in the area of magnetic tape recording.
Latest Patents
One of Seki's latest patents is a piezo-electric bimorph type transducer designed for controlling the scan tracking of a magnetic tape by a rotating head in a helical-scan-type video tape recorder. This innovative transducer features piezo-electric thin plates that are shaped differently from the electrodes attached to them. The design ensures that the width of the electrodes is smaller than that of the piezo-electric thin plates, creating a specific relationship between the bending moment produced by a control voltage and the inertia generated in dynamic conditions. This results in accurate tracking control of the magnetic head.
Another significant patent involves a method and apparatus for detecting defects on the surface of a running object. This invention allows for the detection of flaws, color shading, and other surface irregularities by optically scanning the surface. The system includes a photoelectric element that captures both regularly and irregularly reflected light, enabling comprehensive detection of surface defects regardless of the finish.
