Title: Eiichi Sakai: Innovator in Satellite Communication and Electrophotography
Introduction
Eiichi Sakai is a prominent inventor based in Hachioji, Japan. He holds a total of 14 patents that showcase his contributions to the fields of satellite communication and electrophotography. His innovative work has significantly impacted technology and industry practices.
Latest Patents
One of Sakai's latest patents is a mobile satellite communication system designed for use in moving bodies, such as aircraft. This apparatus allows for communication with satellites through an antenna equipped with a radome. The design compensates for loss due to transmission through the radome and distortion of polarization characteristics within the antenna. The system features variable phase shifters and variable attenuators that are controlled as a single unit in each channel. This allows for optimal control of the entire power EIRP radiated from the antenna, enabling simultaneous radome correction and EIRP control through a relatively simple circuit.
Another significant patent is for an electrophotographic photoreceptor. This invention comprises an insulating support with a conductive layer, an intermediate layer, and a photosensitive layer. The conductive layer has a specific work function, while the intermediate layer possesses an ionization potential. The relationship between these two properties satisfies a defined formula, enhancing the performance of electrophotographic devices.
