Title: Takahisa Arima: Innovator in Optical Technology
Introduction
Takahisa Arima is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of optical technology, holding a total of 4 patents. His work focuses on advancements in optical write heads and light-emitting element matrix arrays.
Latest Patents
One of his latest patents is for an optical write head and method of assembling the same. This invention involves a rod lens array, a substrate support member for supporting a substrate, and a driver circuit board that are fixedly held by a support member. The support member and the substrate support member are made from metallic material, while the frame of the rod lens array is constructed from a glass plate. The distance between the light-emitting section of a light-emitting device array and the light-incident end face of the rod lens array is adjusted using rotating eccentric pins. Additionally, light-emitting device array chips are die-bonded on the substrate at predetermined positions on the substrate support member, with the position of the substrate support member serving as a reference plane.
Another notable patent is related to a light-emitting element matrix array. This invention reduces the cost of the matrix array by implementing a function equivalent to a light-emitting thyristor using different elements. A plurality of combinational elements are arranged in a single line and divided into groups. The bases of transistors in each group are separately connected to base-selecting lines, while the anodes of light-emitting diodes in each group are commonly connected to one anode terminal.
