Title: Innovations of Yoshifumi Ono
Introduction
Yoshifumi Ono is a notable inventor based in Katsuta, Japan. He has made significant contributions to the field of optical scanning systems and laser technology. With a total of 2 patents, his work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is an optical scanning system. This system utilizes a light beam from a laser source that is reflected by a rotating polygonal mirror. The beam is then focused by a scanning lens into a scanning beam spot on the drum surface. A cylindrical lens is positioned between the scanning lens and the drum to correct the unevenness of the scanning line pitch caused by the incline of each facet of the polygonal mirror. This lens has a curvature in the scanning direction of the beam, ensuring that the optimal focal points of the scanning beam spot align on a straight line.
Another significant patent is an apparatus for driving a semiconductor laser for use in a laser-beam printer. This apparatus allows a laser beam from the laser to be deflected to scan a light-sensitive drum and a light-sensitive detector. It includes a first device for determining the operation level for the laser when it scans the drum to record information. Additionally, a second device determines the operation level for the laser when it scans the detector to provide a scanning start pulse signal. A controller manages these devices to alternately enable them, allowing the intensity of the laser beam to be adjusted according to the varying light sensitivity of the drum.
Career Highlights
Yoshifumi Ono has worked with prominent companies such as Hitachi, Ltd. and Hitachi Koki Co., Ltd. His experience in these organizations has contributed to his expertise in optical technologies and laser systems.
