Yoshiaki Ishida has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A chlorosulfonated ethylene..alpha.-olefin copolymer composition is disclosed, comprising(a) 100 parts by weight of a chlorosulfonated ethylene..alpha.-olefin copolymer containing from 25 to 32% by weight chlorine and from 0.3 to 2.5% by weight sulfur,(b) from 10 to 35 parts by weight of a hydrotalcite,(c) from 0.5 to 5 parts by weight of a thiuram, and(d) from 0.5 to 5 parts by weight of a maleimide.The chlorosulfonated ethylene..alpha.-olefin copolymer of the invention provides vulcanized products having excellent heat resistance, cold resistance and water resistance.
Abstract: A method and apparatus for determining the chemical structure of an unknown substance wherein spectral data of the unknown substance is detected, a point-assessment is calculated which expresses the degree of possibility of partial structures being contained in the unknown substance based on the spectral data and prememorized chemical shift values corresponding to the partial structures of known substances, it is judged whether the point-assessment is a predetermined threshold value or more and the partial structures with a large possibility of being contained in the unknown substance based on the output of the judgement results are found and displayed. The partial structures thus found are used to determine a molecular structure of the unknown substance.
