Ikunari Hara 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).

  • Patent number: 9966575
    Abstract: A film-forming composition according to the present invention includes: a fluororesin having a repeating unit of the formula (1) and a repeating unit of the general formula (2); and a fluorine-containing solvent. In the general formula (2), R1 represents a C1-C15 straight, C3-C15 branched or C3-C15 cyclic hydrocarbon group in which at least one hydrogen atom may be replaced by a fluorine atom or chlorine atom and which may have a hydroxy group. This film-forming composition is suitably usable for the manufacturing of an organic semiconductor element as the composition can form a fluororesin film on an organic semiconductor film; and the formed film has resistance to an etching solvent during the fine pattern processing of the organic semiconductor film by photolithography etc.
    Type: Grant

  • Patent number: 9842993
    Abstract: A film-forming composition according to the present invention include fluororesin having a repeating unit of the general formula (1); and a fluorine-containing solvent. In the general formula (1), R1 each independently represents a hydrogen atom, a fluorine atom, a methyl group or a trifluoromethyl group; and R2 each independently represents C1-C15 straight, C3-C15 branched or C3-C15cyclic fluorine-containing hydrocarbon gr which any hydrogen atom may be replaced by a fluorine atom with the proviso that the repeating unit contains at least one fluorine atom. This film-forming composition is suitably usable for the manufacturing of an organic semiconductor element because the composition can form a film on an organic semiconductor film; and the formed film has resistance to an etching solvent during the fine pattern processing of the organic semiconductor film by photolithography etc.

  • Publication number: 20110122903
    Abstract: In a laser apparatus including an excitation light source and a resonator in which a laser medium is disposed between optical paths of a first mirror reflecting light in a desired wavelength band and a second mirror and a first wavelength selecting means is disposed between optical paths of the laser medium and the second mirror, there is provided a wavelength-variable laser apparatus capable of continuously varying the laser oscillation wavelength by using at least a Pr3+-doped fluoride glass in the laser medium.
