Abstract: An apparatus for detecting a break in a warp yarn in a loom includes a heald, a heald frame, a carrier rod, a sensor, a controller and a signal line. The heald is made of a resin material for guiding a warp yarn. The heald frame performs a shedding operation of warp yarns and has the carrier rod for supporting a plurality of the healds. The sensor is provided in the heald for sensing a deformation of the heald caused by a tension of the warp yarn and outputting a signal. The controller is provided for determining a condition of the break in the warp yarn based on the signal of the sensor. The signal line electrically connects to the sensor and the controller.

Abstract: A heald frame has a frame stave, a carrier rod provided along the frame stave and a heald made of a resin material. A plurality of healds are supported by the carrier rod and arranged in a row. A magnet having N and S poles is provided in each heald and the healds are arranged so that the adjacent ends of any two adjacent magnets are of the same polarity.

Abstract: A method for updating a PLU file in a POS terminal. A slip having a dedicated format for printing data corresponding to a not-yet-registered article is prepared in advance of a retail transaction. When the not-yet-registered article is encountered during the retail transaction, a message is displayed on a display of the POS terminal to inform the operator that the particular article is not registered in the PLU file. The operator then inserts the dedicated slip into a print slot of a printer on the POS terminal in order to print article data (such as a message that the article is not-yet-registered, a code number for the article, a date and time for the transaction, and the like) thereon. The dedicated slip is handed over to the manager of the store who then updates the PLU file to include information (such as unit price and article name) for the not-yet-registered article.
