Title: Kenji Tokunaga - Innovator in Current Sensor Technology

Introduction

Kenji Tokunaga is an inventive mind based in Kariya-city, Japan. He has made significant contributions to the field of current sensor technology. Although he currently holds no granted patents, his innovative ideas are reflected in his latest patent applications.

Latest Patent Applications

Kenji Tokunaga's recent patent applications include two notable designs for current sensors. The first application describes a bus bar of a current sensor that features a side face of a current path portion intersecting with a width direction. It includes a first extension portion that extends in the width direction from a region of the side face where the current path portion protrudes from a case. Additionally, a second extension portion is connected to the first and extends in a direction that intersects with the first extension portion. This design allows the second extension portion to deform in the thickness direction while maintaining contact with the case when the current path portion deforms. The second application outlines a current sensor that consists of a bus bar, a core with a core hole, a gap forming portion, a core lateral portion, and a core bottom portion, along with a detection unit located in a gap. Notably, the magnetic permeability of the core lateral portion differs from that of the core bottom portion.

Conclusion

Kenji Tokunaga's work in current sensor technology showcases his innovative spirit and potential for future contributions to the field. His latest patent applications reflect a commitment to advancing technology, even in the absence of granted patents.
