Title: Toshihiko Minatoya and Cellulose Triacetate Film Innovation.
Introduction
Toshihiko Minatoya is an inventor associated with Minamiashigara, Japan, and Fuji Photo Film Company, Limited. His work includes a patent for cellulose triacetate film designed to improve performance in low-temperature conditions.
Latest Patents
Minatoya is credited with 1 patent: “Cellulose Triacetate Film and Process for Producing the Same.” The invention describes a film with a thickness of 115 to 135 micrometers and a Z value of 0.3 or less, where the Z value represents the slope of tear strength across a specified temperature range. Its production process controls the temperature of the drying wind in relation to an inflection point in the film’s tear-strength response. The resulting film is intended to provide strong performance at low temperatures and resist perforation breakage during rewinding.
Career Highlights
Minatoya’s patent reflects work on both material properties and manufacturing conditions. By linking film thickness and tear strength to the drying process, the invention addresses the practical challenge of producing cellulose triacetate film that remains durable in cold environments.
Collaborations
The supplied information identifies Atsushi Adachi and Satoshi Sakamaki as Minatoya’s coworkers. They are also associated with Fuji Photo Film Company, Limited.
Conclusion
Toshihiko Minatoya’s patented work focuses on improving the low-temperature strength and handling durability of cellulose triacetate film through carefully controlled production conditions.
