Title: Koji Yao: Innovator in Exposure Control Technologies
Introduction
Koji Yao is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of exposure control technologies, holding a total of 4 patents. His work focuses on improving the efficiency and precision of exposure systems used in various imaging applications.
Latest Patents
One of Yao's latest patents is a method and device for controlling exposure beams. This innovation involves a D-A converter that outputs feed pitch error signals on an exposure head. The error signals are inverted and supplied to a multiplier, while non-inverted signals are sent to a second multiplier. The exposure head radiates multiple beams, with ON/OFF dot signals for odd channels supplied to one multiplier and even channels to the other. This system allows for the adjustment of power intensity in the beams, thereby changing the diameters of printing spots on photosensitive material per channel.
Another notable patent is a method and apparatus for loading and unloading film on a rotary drum in exposure and recording apparatuses, such as raster plotters or color scanners. This invention automates the replacement of films using a supply pallet and a discharge pallet, along with suckers and maneuverable linkages. This innovation enables the film to travel seamlessly from the supply pallet to the drum and back to the discharge pallet after exposure.
