Title: The Innovations of Yoshimitsu Hisajima
Introduction
Yoshimitsu Hisajima is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of semiconductor manufacturing, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of machinery used in this critical industry.
Latest Patents
His latest patents include a Pellet Conveying Device and a Semiconductor Manufacturing Apparatus Having a Movable-Area Covering. The Pellet Conveying Device is designed for use with bonding machines, particularly in semiconductor devices. It features a conveying arm equipped with a collet for holding pellets, which can move vertically and pivot horizontally through two different driving sources. This allows the collet to transition between a pellet pick-up position and a pellet releasing position seamlessly.
The Semiconductor Manufacturing Apparatus includes a covering mechanism that utilizes a flexible sheet cover with elasticity. This cover is fastened to a take-up shaft at one end, while the other end is attached to a movable member that operates over the movable table. As the movable member shifts away from the take-up shaft, the cover stretches out to cover the table. Conversely, when the movable member moves towards the take-up shaft, the cover retracts back around the shaft. This innovative design allows for multiple take-up shafts arranged at right angles, enabling the covers to stretch in perpendicular directions and cover a wider area.
