Title: Hiroaki Tetsuka: Innovator in Air Conditioning Technology
Introduction
Hiroaki Tetsuka is a prominent inventor based in Gunma, Japan. He has made significant contributions to the field of air conditioning technology, holding a total of 6 patents. His innovative work focuses on the development of advanced materials and methods for improving air conditioning systems.
Latest Patents
One of Tetsuka's latest patents is an air conditioning system that utilizes a permeable membrane. This membrane allows for the supply of air to a space being conditioned and facilitates gas discharge from that space. The asymmetric membrane is crafted from a cyclic olefin addition polymer, which is derived from the addition polymerization of cyclic olefin functionality siloxane. The polymer's structural unit derived from the cyclic olefin functionality siloxane constitutes 5 to 100 mol % of the addition polymer, with a number average molecular weight (Mn) ranging from 10,000 to 2,000,000, as measured by GPC using tetrahydrofuran as a solvent.
Another notable patent involves a method for preparing a cyclic olefin addition polymer with high gas permeability. This method includes the addition polymerization of a specific type of cyclic olefin-functional siloxane and a cyclic olefin compound in the presence of a multi-component catalyst. The resulting polymer has a structural unit ratio derived from the cyclic olefin-functional siloxane of 10 to 100 mole % and a number average molecular weight (Mn) between 100,000 and 2,000,000.
