Title: Innovations of Taiichi Nakagawa

Introduction

Taiichi Nakagawa is a notable inventor based in Himeji, Japan. He has made significant contributions to the field of engineering, particularly in the design of starter mechanisms for engines. With a total of 5 patents to his name, Nakagawa's work showcases his innovative approach to solving technical challenges.

Latest Patents

One of Nakagawa's latest patents is the "Pinion stopper for starter." This invention involves a section of the normal internal bore of a starter pinion gear drive mechanism, which is enlarged in diameter. This design allows the drive mechanism to slide over the starter drive shaft. When the pinion gear engages the flywheel of an engine, the enlarged bore section slides over a snap ring stop on the drive shaft. The snap ring limits the travel of the pinion gear drive mechanism, effectively sealing the outer end of the enlarged bore to prevent dirt from reaching the starter drive shaft.

Another significant patent is the "Engine starter with a pinion shifter unit." This engine starter features an elongated pinion shifter unit that is axially slidably mounted on an output rotary shaft coupled to a d.c. motor. The unit includes a pinion mounted at one end and a unidirectional clutch at the other. The design incorporates two sleeve bearings made from materials that are wear-resistant under different conditions, allowing for smooth axial sliding movement even when the output rotary shaft is bent.
