  • Pharmaceutical tablet and production method thereof
    Patent number: 11395800
    Abstract: An object of the present invention is to provide a pharmaceutical tablet having high tensile strength and excellent in immediate disintegrability. The pharmaceutical tablet of the present invention is obtained by a direct compression method, and contains an active ingredient, a polyvinyl alcohol resin, and a plasticizer other than water, wherein a content of the plasticizer is 1 to 8 parts by weight with respect to 100 parts by weight of the polyvinyl alcohol resin.
    Type: Grant
    Filed: February 7, 2020
    Date of Patent: July 26, 2022
    Assignee: MITSUBISHI CHEMICAL CORPORATION
    Inventors: Chizuko Furo, Ayaka Kobayashi, Hirofumi Takeuchi, Yoshiko Takeuchi
  • Steel plate and method of producing same
    Patent number: 11299798
    Abstract: Excellent CTOD properties for multilayer welding joint is provided for a steel plate. The steel plate comprises a specific chemical composition with Ceq of 0.45% or less where Ceq (%)=[C]+[Mn]/6+([Cu]+[Ni])/15+([Cr]+[Mo]+[V])/5 . . . (1) and Pcm of 0.22% or less where Pcm (%)=[C]+[Si]/30+([Mn]+[Cu]+[Cr])/20+[Ni]/60+[Mo]/15+[V]/10+5 [B] . . . (2); an average effective grain size of 20 ?m or less at a mid-thickness part of the steel plate; and porosities having an equivalent circular diameter of 200 ?m or more, the number of the porosities per mm2 being 0.1/mm2 or less.
