Title: Kiyoo Katagiri: Innovator in Measurement Technology
Introduction
Kiyoo Katagiri is a notable inventor based in Niigata, Japan. He has made significant contributions to the field of measurement technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Automatic Dimension Analyzer." This invention features a power-driven table that allows for precise measurements of objects placed on it. The table can move in orthogonal directions, and an optical system forms an image of the object in a sample point field. The sample point field is electronically scanned to produce data bits representing various optical levels. A cursor generator works in synchronization with the raster to create a cursor in the sample point field. A coincidence detector identifies when a sample point data bit matches the cursor, enabling accurate measurements. The system utilizes a microprocessor to retrieve measurement instructions from memory, allowing for relative movement between the table and cursor to detect positions accurately.
Another significant patent is the "Method for Controlling Thickness of Wafer-like Work Pieces Under Lapping." This invention improves the lapping method for wafer-like work pieces by using a sensor mounted on the upper surface plate of a lapping machine. Unlike conventional methods, this approach computes the thickness of the work pieces at regular intervals, eliminating errors caused by machine vibrations and undulated revolutions. This innovation leads to enhanced control over the thickness of work pieces during the lapping process.
