Title: **Yoshio Mikuni: A Pioneer in Sewing Machine Technologies**

Introduction

Yoshio Mikuni is a renowned inventor based in Osaka, Japan, with an impressive portfolio of 7 patents to his name. His innovations primarily focus on advancements in sewing machine technology, contributing significantly to the efficiency and functionality of these essential tools in the textile industry.

Latest Patents

Two of Mikuni's latest patents exemplify his ingenuity. The first is a **Thread Take-up Lever Device for Sewing Machines**, which features a mechanism that guides the upper thread vertically using a pair of opposed thread guides. This innovative design allows for horizontal reciprocation of the thread take-up lever, efficiently engaging the thread to draw it in a V-form during its forward travel while creating a slack in the return travel. To enhance this mechanism, a thread holding member made from easily deformable material is implemented to prevent the slacked thread from clinging to the lever.

The second recent patent is a **Thread Tension Device for Overedge Sewing Machines**. This invention integrates several tension disk assemblies that are axially distributed along a rotating shaft. Each assembly engages a thread tensioning mechanism, where the first tension disk can move axially against the second, immovable disk. The system utilizes a cam device to convert rotary motion into linear motion, effectively relieving the tensile force on the thread simultaneously across multiple assemblies.
