  • Publication number: 20230314118
    Abstract: Strain sensors are attached to a workpiece, and resistance values of the strain sensors are measured with time while cutting the workpiece with a milling cutting machine. A power spectrum in a frequency domain is obtained by Fourier-transforming the resistance values measured with time. A power peak is found in the power spectrum to be outputted as a magnitude of vibration occurring during machining the workpiece. By attaching a strain sensor to a stamper of a plastic working machine, a resistance value of the strain sensor is measured while pressing a workpiece on a die with the stamper. A magnitude of the strain corresponding to the measured resistance value is used to obtain a corresponding plastic working force. By attaching the strain sensor directly to the workpiece, it is possible to monitor the state of the plastic working and/or cutting process of the workpiece with high precision at low cost.

    Abstract: Disclosed are modularized garment manufacturing method and system for small quantity batch production of garments. Basic components constituting an ordered garment are generated by analyzing shape graphic data of the ordered garment. For each basic component, basic patterns are generated for each dimension of the ordered garment. The basic patterns are compared with reference garment patterns stored in a garment pattern database to determine a pattern category of each basic pattern. Based on the pattern category of the basic patterns and information on garment production lines currently in operation, subdivided work modules are determined for each basic pattern.

  • Patent number: 11655279
    Abstract: The present invention relates to a method for producing an active form of a long-acting insulin analogue derivative, in which the amino acid at position 22 of the insulin B-chain is substituted from arginine (Arg) to lysine (Lys), so that the insulin analogue can be converted to an active form without cleavage of the B-chain even when it is reacted with clostripain. In a conventional method of converting pro-insulin to an active form by use of trypsin, an albumin binding domain is cleaved, making it difficult to convert the long-acting insulin analogue derivative to an active form. The production method according to the present invention overcomes this difficulty, and thus it can be effectively used for the production of a long-acting therapeutic agent for treatment of diabetes.
