Introduction

Yusaku Niida is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of mechanical timepieces, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is a mechanical timepiece that features a hairspring, a permanent magnet, a soft magnetic core, and a control circuit. This invention performs rate adjustment based on a counter-electromotive voltage caused in a coil by the motion of the permanent magnet. The design allows for precise functionality as the permanent magnet is arranged to direct magnetization towards either end of the hairspring when it reaches an equilibrium length.

Another significant patent is a speed governor for timepieces. This governor includes a balance spring made from silicon and a balance wheel. The balance spring is coated with a DLC film to enhance its strength. Notably, the spring constant of the balance spring and the moment of inertia of the balance wheel are designed to change with temperature variations. This innovative approach helps suppress changes in the oscillation period due to temperature fluctuations.
