  • Patent number: 10071618
    Abstract: The embodiment provides a tonneau cover device. The tonneau cover device includes a tonneau cover and a fixing device to engage with a lock portion to thereby hold the tonneau cover in a pulled-out-and-held state. The fixing device includes: a slider provided in a slidable manner and a hook provided in a swingable manner. When a force is exerted on an engagement protruding portion of the hook as a result of pushing in the tonneau cover toward the winding direction from the pulled-out-and-held state, and the exerted force acting on the engagement protruding portion is larger than the normally-given urging force acting on the engagement protruding portion, the hook swings such that the engagement protruding portion retracts into the case while causing the slider to be pushed in away from the sidewall, thereby being disengaged from the locking portion.

  • Publication number: 20140235822
    Abstract: The present invention provides a method for producing a peptide, characterized in that it comprises converting an —SH group of a peptide comprising an amino acid residue having the —SH group to an —OH group, wherein said method comprises the following steps (a) to (c): (a) allowing an —SH group in a peptide to react with a methylating agent to convert the —SH group to an -SMe group; (b) allowing the -SMe group obtained in the step (a) to react with a cyanizing agent to produce a reaction intermediate; and (c) converting the reaction intermediate obtained in the step (b) to a peptide comprising an amino acid residue having an —OH group under more basic conditions than the conditions in the step (b).
