Title: Innovations of Yukio Kasuya
Introduction
Yukio Kasuya is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of image reproduction technology. With a total of 8 patents to his name, his work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is an image reproducing apparatus controlled in response to detected density. This apparatus features an optical system for scanning an original, a developing unit, a fixing unit, a differential amplifier, and a microcomputer. It allows for proper measurement of original image density in any mode of the apparatus. The image is reproduced with optimal density through a lamp control voltage from the differential amplifier. Additionally, it can indicate toner deficiency with minimal displays and/or indicators. Upon detecting toner deficiency, the current copying cycle is completed, and the apparatus is stopped, allowing the copying operation to resume once the issue is resolved.
Another notable patent is the direct-contact-type image sensor. This sensor comprises an array of photosensor elements that receive light reflected from a document. A protective layer is placed above the array to safeguard it during contact with the document. The design includes means for discharging electric charges accumulated on the protective layer, which may consist of a protective layer with relatively low resistivity or a separate conductive layer.
