Title: The Innovations of Yoshiharu Tomida
Introduction
Yoshiharu Tomida is a notable inventor based in Chiryu, Japan. He has made significant contributions to the field of engineering, particularly in the development of starter systems for engines. With a total of 2 patents, his work has had a lasting impact on automotive technology.
Latest Patents
One of his latest patents is for a "Starter having improved electromagnetic switch." This invention features an electromagnetic switch designed to control the electric power supply to a starting motor. The switch is strategically located in the periphery of one side of an output shaft, ensuring efficient operation. It includes a motor contact that connects to a power supply circuit, which supplies electric power to the brushes. The design allows for a battery-side fixed contact that is integrally formed with a battery terminal, along with a motor-side fixed contact connected to a positive brush. Additionally, the movable contact is held by a plunger's end. In cases where the electromagnetic switch is not coaxially aligned, it is designed in a flat form, positioned parallel to the output shaft.
Another significant patent is the "Engine starter mounting structure." This innovation involves a starter that includes a pinion supported in a housing, which engages with a ring gear fitted to a crankshaft. The starter motor is fixed to the housing and drives the pinion through a speed reduction mechanism. This design allows the starter to be mounted on an engine block in a way that positions the motor's axis center closer to the ring gear's axis center, thereby reducing rotary vibrations of the starter motor.
