Abstract: A laundry tag is obtained having excellent solvent-resistant and water-resistant adhesive layers, which is durable to both dry cleaning and washing with water. The laundry tag comprises an elongated substrate 1, a solvent-resistant adhesive 3 on one side at distal ends thereof and water-resistant adhesive layers 3 in the inner side of said solvent-resistant adhesive. After the tag is threaded through part of the laundry item, the adhesive layers 2, 3 are adhered to each other so that the tag will form a loop. The laundry item is dry cleaned and washed with water while the laundry tag is attached to the laundry item.

Abstract: An improved technique for pre-processing a picture image data signal wherein a black/white image data and a halftone image data coexists, is disclosed. The pre-processing is implemented before run-length encoding. Each of line image data signals is divided into n data blocks (n is a positive integer). A reset signal is produced in synchronism with each of the data blocks when divided. Following this, a selector is supplied with a first line image data signals directly applied and also receives the first line image data via a convolution circuit to said selector. The number of transition points in each of the data blocks is counted with respect to the first line image data signal which is directly applied to said selector. Similarly, the number of transition points in each of the blocks is carried out with the first line image data signal which is applied to said selector via said convolution circuit.
