Title: Takayuki Wakana: Innovator in Sewing Machine Technology

Introduction

Takayuki Wakana is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of sewing machine technology, holding 2 patents that showcase his innovative approach to enhancing sewing machine functionality.

Latest Patents

Wakana's latest patents include a "Sewing Machine Drive Apparatus and Method." This invention features a sewing machine apparatus driven by a motor, which is subject to velocity control based on a detector that determines the rotary position and/or velocity of the motor output shaft. A controller is designed to manage the motor's speed according to a velocity command value. Additionally, a mechanism generates a holding force during the sewing machine's stop, ensuring that the sewing needle remains stationary and does not move unintentionally. This holding force can be adjusted when movement from the stop position is required, which is particularly beneficial for operators wishing to manually reposition the machine.

Another significant patent is the "Method and Apparatus for Controlling a Sewing Machine." This sewing control system regulates the speed of rotation of a sewing machine. In one embodiment, the rotation transfer ratio operation is inhibited during slip occurrences. In another, the rotation transfer operation is initiated only when the motor shaft's revolutions exceed a predetermined value. Further embodiments focus on preventing slip by avoiding speed instructions that are not steeper than a specific gradient. Additionally, when an abnormal condition is detected, the rotation transfer ratio is reduced to ensure the operator's safety.
