  • Patent number: 12240871
    Abstract: The present invention is to provide a method for producing a peptide containing an N-alkylamino acid, which comprises the following Steps (1) to (3). Step (1): a step of mixing an N-terminal protected amino acid or an N-terminal protected peptide with a carboxylic acid halide or a halogenated alkyl formate; Step (2): a step of mixing an amino acid or a peptide in which the N-terminal and the C-terminal are not protected with a trialkylsilylating agent; and Step (3): a step of mixing the product obtained in Step (1) with the product obtained in Step (2).

  • Patent number: 4779956
    Abstract: A liquid crystal display having plural liquid crystal cells which are constituted as a matrix, each cell respectively having one transistor and being supplied with image signals by such transistors. The driving circuit for a liquid crystal display of the present invention periodically changes the polarity of the voltage of the image signals and the voltage between both terminals of the liquid crystal cell so as to switch the transistor, and the driving circuit generates gate signals which are impressed on the gate electrode of each transistor, the gate signals having a lowest voltage which is lower than a voltage obtained by subtracting the amplitude voltage of the common electrode of the liquid crystal cells from the lowest voltage in the driving voltage obtained from the image signals.

  • Patent number: 4734692
    Abstract: A driver circuit for a liquid crystal display for driving a liquid crystal panel in an A.C. manner. In this circuit, a display signal voltage to be applied to one electrode of the liquid crystal cell and a common voltage to be applied to a common electrode thereof are inverted in their polarity with a certain period, respectively, and at least one of the signal voltage and common voltage that are being polarity-inverted with the certain period is varied in its D.C. level by the same amount in the same direction in each period so that they can be adjusted so as to be in a predetermined relation for A.C. driving.
