Title: The Innovative Mind of Tadashi Komiyama: Contributions to Lens Technology
Introduction: Tadashi Komiyama is a renowned inventor from Nagano, Japan, known for his significant contributions to optical technologies. With an impressive portfolio of 14 patents, Komiyama's work focuses on improving lens units, particularly in regard to their performance under varying temperature conditions.
Latest Patents: Among his latest innovations are two notable patents. The first is a lens unit that maintains suitable image formation characteristics despite temperature fluctuations. This innovative design features a fourth lens whose outer peripheral face does not come into contact with the inner peripheral face of a second accommodation part. Additionally, a fifth lens is constructed from glass, is press-fitted, and secured within a resin-made lens holder, culminating in an integrated fifth lens body that fits within a lens-barrel. Furthermore, the lens holder incorporates a stepped part to engage with a corresponding geometry in the fourth lens. The design ensures that the outer peripheral face of the fifth lens body comes in contact with the inner surface of the second accommodation part, thus enhancing overall image quality.
The second patent pertains to a wide-angle lens containing seven sequentially arranged lenses, which include a diaphragm and key elements designed to optimize image capture. This lens configuration is ingeniously set to satisfy the condition of d/HEP < 29.000, where 'd' represents the object-to-image distance and 'HEP' denotes the entrance pupil diameter of the wide-angle lens.
Career Highlights: Komiyama's work is primarily associated with Nidec Sankyo Corporation, a company recognized for its dedication to precision optical technologies. Throughout his career, he has consistently demonstrated a commitment to advancing lens performance, making significant strides in the field.
