Title: Innovations of Katsumi Momose
Introduction
Katsumi Momose is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of technology, particularly in the areas of head positioning devices and semiconductor manufacturing. With a total of 4 patents to his name, Momose's work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a device for head positioning using a disk drive mounted to a rotating table. This innovative device detects the position of an information recording or reproducing head relative to a recording medium. The head is designed to be rotatable around a first axis with respect to the recording medium and around a second axis parallel to the first axis. The device includes an autocollimator for measuring the relative positional relationship of the head along the direction of rotation around the second axis. A rotating table is utilized to activate the rotational movement, and a control unit adjusts the table's rotation based on the head's position. This results in a compact and high-accuracy head positioning device.
Another significant patent by Momose is a method of aligning a mask and a wafer for manufacturing semiconductor circuit elements. This method involves two steps. In the first step, the mask and wafer are aligned using relatively large alignment marks. In the second step, smaller key patterns are used for alignment, ensuring minimal positional deviation with respect to actual circuit patterns.
