Title: Method of detecting label
Inventor: IHARA TORU
IPC: G01B5/20
Filed: 1989-03-31
Abstract: PURPOSE:To prevent the erroneous labeling by detecting the incorrect position of a labeler by a sensor which is provided on a shooter of the labeler. CONSTITUTION:Among four notches on the four corners of a label 1, a notch 2 at one corner is formed larger than three other notches 3, and is made a notch for detection 2. Also, at the top of a shooter, an ultrasonic switch sensor 6 which can detect the label 1 which protrudes from a shooter 5 because of the mis-match between the notches 3, 3 and guides 7, 8 is provided. When the label 1 is set on the shooter 5, the label protrudes from the shooter 5 due to the upside down condition of the label, and distance (h) between the protruding label and the sensor 6 becomes shorter than when the label is guided to the correct position. Therefore, the discrepancy of the distance (h) is automatically detected by the sensor 6. By this method, the incorrect position of the label can be detected.

Title: Two-dimensional code
Inventor: SHIGEKUSA HISASHI
IPC: G06K19/00
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a two-dimensional code which can realize appropriate reading even in the case an inclined reading that is not affected by mirror reflection is performed and also can realize such basic requirement that the size of the entire codes is to be reduced by using a cell as small as possible. SOLUTION: When the horizontal and vertical cell dimensions of a cell constituting a two-dimensional code 52 are defined as (w) and (h), respectively, the cell is made rectangular satisfying (h)>(w) (≈1.2). The horizontal dimension is equal to a dimension measured from the perpendicular direction as in the conventional practice, and only the vertical direction is defined as about 1.2 times as long as the dimension measured from the perpendicular direction. Because of its vertically elongated shape, even though the two-dimensional code is read from a direction inclined from the normal and a cell image is formed in a distorted state, a value being close to the correct dimension is secured easily at least in the cell length in the vertical direction.  That is, in the case where the reduction rate is within (1/1.2) times vertically even in a cell whose distortion rate is the largest when inclined reading is performed, the same dimension as in a case of the perpendicular reading can be secured, and the center position of the cell can be easily determined.

A branching unit 2 branches the input signal and they are added to the first to third paths. The input signal containing the non-linear distortion component is added to the non-linear circuit 5 and the amplitude ratio between the signal component and the non-linear distortion component is varied from that of the input signal. The non-linear distortion component generated on a transmission side is extracted by using the difference of the amplitude ratio and the amplitude ratio with the non-linear distortion component of the input signal passing through the delay line 4.  A synthesizer 9 synthesizes the extracted non-linear distortion component and the non-linear distortion component contained in the input signal component so that they compensate each other. Thus, the non-linear distortion component is reduced.
