Abstract: A cell stack manufacturing device for secondary batteries is disclosed. The cell stack manufacturing apparatus for secondary batteries is characterized in that tension of a separator is controlled by adjusting the rotational speed of a feeder roll. In addition, the cell stack manufacturing device for secondary batteries is characterized in that tension of a separator is adjusted by adjusting the rotational speed of the feeder roll according to the moving speed and/or moving position (trajectory) of a guide roller. In addition, the cell stack manufacturing device for secondary batteries is characterized in that tension of a separator is controlled according to the moving speed and moving trajectory of the guide roller. The cell stack manufacturing device for secondary batteries includes a separator supply unit, a tension adjustment unit, and a stack stacking unit. The tension adjustment unit includes a feeder roll rotated by a feeder roll driving unit to adjust tension of a separator.

Abstract: The disclosure relates to a dish washer, which can prevent user's scald, improve safety, and effectively prevent an inner moisture condensation phenomenon by starting an operation of a dry air supply part or switching an operation mode of the dry air supply part by using a door position sensing part capable of clearly sensing and specifying the position of a door. In this regard, a dish washer comprises a tub (20) configured to accommodate an object to be washed and provided with a washing space (21) having an open front; a door (30) provided rotatably between a closing position (P1) for closing the front of the washing space (21) and a full opening position (P2) for entirely opening the front of the washing space (21); and a door position sensing part (36) configured to sense a position of the door (30), wherein the door position sensing part (36) is configured to sense whether the door (30) moves from the closing position (P1) and whether the door (30) reaches a risk area start position (P4) formed between the closing position (P1) and the full opening position (P2).
