    摘要: A thread loop taker device for a zigzag sewing machine having a needle whose position is controlled by electronically stored data which cooperates with the thread loop taker device to thereby produce zigzag stitches. The thread loop taker device comprises a bobbin carrier, a rotational cylindrical member for supporting the bobbin carrier therein; a loop taker coaxial with and about the cylindrical member for rotation therewith, the loop taker having a beak extending from one end and in the direction of the rotation around a portion of the cylindrical member for catching a thread loop formed by the needle; cams rotating with the cylindrical member and engaging the opposite end of the loop taker for rotating the beak relative to the cylindrical member; and a pulse motor movable in two opposite directions in response to a change in the position of the needle so that, when this movement is transmitted to the cams, the loop taker is actuated. Thus, the beak rotates relative to the cylindrical member in response to a change in the position of the needle during rotation of the cylindrical member.

Thus, the beak rotates relative to the cylindrical member in response to a change in the position of the needle during rotation of the cylindrical member.

    摘要: A method of extracting timing characteristics from transistor circuit data of modularity design products (a module) such as a CPU core in which the extracted timing characteristics are used for the timing verification of a circuit including a module to be extracted and timing constraints when logical synthesis or timing-driven layout is made. Particularly, since conditions fit for a timing rule of the module are included in timing characteristics when timing verification is executed by simulation, verification free of pseudo error is enabled. Also, the configuration of a timing characteristic library, a storage medium storing it and an LSI designing method using the storage medium are provided.
