Title: Hiroyoshi Takeuchi: Innovator in Voltage Supply and Titanium Processing
Introduction
Hiroyoshi Takeuchi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of voltage supply apparatus and surface processing techniques. With a total of 3 patents to his name, Takeuchi's work reflects a commitment to innovation and technological advancement.
Latest Patents
One of Takeuchi's latest patents is a voltage supply apparatus. This apparatus includes a primary cell and a constant voltage supply unit. The constant voltage supply unit is designed with a voltage drop determination value, which serves as a threshold that is higher than a positional-data loss level and lower than a second output voltage. This second output voltage is a constant voltage that the unit outputs when in a steady state. The unit converts the first output voltage of the primary cell to the second output voltage and supplies it to the absolute-position detection apparatus until the first output voltage falls below the threshold. When this occurs, the unit converts the first output voltage to a third output voltage, which matches the threshold level, and supplies it to the absolute-position detection apparatus.
Another significant patent by Takeuchi is a method for lapping two surfaces of a titanium disk. This method involves inserting a titanium disk into an opening in a disk-type carrier. The carrier rotates and revolves between two parallel surface plates that apply lapping pressure to the titanium disk. Abrasives are fed between the surface plates and the titanium disk, ensuring a specific relationship between the thickness of the titanium disk and the thickness of the carrier.
