Latest Patents

One of Jeongdai Jo's latest patents is an "Apparatus and method of measuring web feeding velocity by using single field encoder." This invention provides a method for measuring the feeding velocity of a web that has a scale with pitches differing from those of a mask. The method involves calculating the number of vibrations of a moiré image of light passing through the mask and the scale. It also includes averaging the pitches of the scale to minimize changes between adjacent timings, extracting signals for one pitch, and calculating the feeding velocity based on the angle of a Lissajous circle formed by the signals.

Another significant patent is the "Printing apparatus having automatic printing sheet feeder." This invention integrates an automatic printing sheet feeder into a printing apparatus to enhance mass productivity. The apparatus consists of a base, a moving stage, an automatic printing sheet feeder, and a printing roll. The moving stage is designed to be linearly movable and supports a lithographic plate with a printing pattern. The automatic printing sheet feeder includes components that guide the printing sheet through the printing area, ensuring efficient operation.
