Title: The Innovative Contributions of Kasumi Yamamoto
Introduction
Kasumi Yamamoto is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of electrophotographic technology, holding a total of 4 patents. Her work focuses on improving the efficiency and safety of printing devices, particularly in managing ozone emissions.
Latest Patents
Yamamoto's latest patents include an innovative exit-structure for an ozone-exhaust duct incorporated in electrophotographic printers. This design effectively exhausts air containing ozone and dust particles while integrating an ozone-filter. The exit structure features a dust trapper positioned near the ozone-filter, creating a dust-trapping chamber. This design increases the cross-sectional area of the duct's exit end, which slows down the velocity of the air, allowing gravity to trap dust particles effectively.
Another notable patent is her design for a fixing unit used in electrophotographic printers. This unit includes a heat roller that accommodates a heater and a press roller that can move between a retracted and an operating position. The heat roller is driven by a mechanism that allows the press roller to open and close the gap between them, ensuring efficient image fixing on recording sheets.
