Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To apply a pressure-sensitive adhesive, in a specified coating pattern, on a label base material while coating the pressure-sensitive adhesive all over the label base material and reduce a manufacturing cost relative to the application of the pressure-sensitive adhesive. SOLUTION: A transparent ink comprising a hydrophobic component is previously printed, in a negative pattern as a coating pattern, on the pressure- sensitive adhesive-coated face side of a label base material 1 to form a pressure- sensitive adhesive non-coated area 2. After this procedure, an aqueous pressure- sensitive adhesive is applied to the entire area of the pressure-sensitive adhesive- coated face as a coating range, on the pressure-sensitive adhesive-coated face side, and application of the pressure-sensitive adhesive to the surface of the pressure-sensitive adhesive non-coated area 2 is made impossible by the hydrophobic properties of the pressure-sensitive adhesive non-coated area 2. Thus a pressure-sensitive adhesive-coated area 3 is formed only on the coating pattern part.

Title: Aspect conversion circuit
Inventor: HATTORI ICHIRO
IPC: H04N7/01
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To decrease the number of memory cells which are needed for conversion processing of an aspect ratio. SOLUTION: A switch string 13 is controlled and selected by a write clock circuit 12 to divide the pixel strings arrayed in sequence in the horizontal scanning direction into plural blocks. The input image data are stored in a memory block 14 consisting of cells equal to one of divided blocks. Then every stored value selects a memory cell via a switch string 16 controlled by the clock of a read clock circuit 15 and then outputs it through an output terminal 17. Under such conditions, the reading time is shortened according to the writing time and the number of cells is set so as to complete a reading operation when a writing operation equal to a single line is completed.  The number of memory cells where the coincidence is secured between the reading time and the writing time is set after the writing and reading operations of a single block are defined as one round and repeated in several times in 1H. Thus the writing and reading operations are defined as one round and repeated in plural times in 1H. As a result, the number of necessary memory cells is extremely decreased compared with the number of pixels equal to 1H.
