Publication number: 20150107740Abstract: The present invention provides a kerf structure for a snow tire, including unit structures on each of which spiral-shaped protrusions are continuously formed to be spaced a predetermined distance apart on the outer circumferential surface of a semi-cylindrical shaped column, wherein the continuously formed unit structures are arranged by alternating convex and concave portions in a zigzag formation, which is capable of optimizing the rigidity which can maintain gripping force as an original function of a kerf while ensuring a friction force generated from small blocks of a tread portion partitioned with kerfs by collapsing a block at an optimum level and further ensuring the kerf function on snow even in the last stages of tread wear by lowering the rigidity of the blocks of the tread portion.Type: ApplicationFiled: October 13, 2014Publication date: April 23, 2015Inventors: Sang Tak JOO, Sung Hee YOUN, Su Jin SON, Myoung Joong LEE, Sang Moo LEE, Mu Yeong KIM

Publication number: 20150107739Abstract: The present invention relates to a kerf structure for a snow tire, including a wave-shaped straight portion and an expansion portion formed expanding from the straight portion, wherein the expansion portion includes unit structures, on each of which central semi-sphere holes and polygonal forms around the semi-sphere holes form protrusions in opposite directions are formed continuously. According to the present invention, the kerf structure for a snow tire provides a symmetric shape, thereby securing uniform block rigidity regardless of the direction of the kerf, and the interlocking effect can be maximized through the combination of the protrusion shape of the polygonal shape and the embossing of the semi-sphere hole.Type: ApplicationFiled: October 13, 2014Publication date: April 23, 2015Inventors: Sang Tak JOO, Sung Hee YOUN, Su Jin SON, Myoung Joong LEE, Sang Moo LEE, Mu Yeong KIM

Patent number: 8685166Abstract: Provided is an apparatus for continuously fabricating superconducting tapes. An evaporation using drum in dual chamber (EDDC) method is suitable for mass production of high-temperature superconducting tapes. However, the EDDC method is limited to fabrication of high-temperature superconducting tapes having a limited length. In an attempt, high-temperature super-conducting tapes having a sufficiently large length can be fabricated using the EDDC method by releasing a long high-temperature superconducting tape from one reel and winding the long high-temperature superconducting tape around the other reel. In this case, it is important to stably move a high-temperature superconducting tape spirally wound around a drum from one reel to the other reel. Therefore, the provided apparatus uses endless tract belts separately disposed around a drum to stably and continuously move a high-temperature superconducting tape spirally wound around the drum along the centerline of the drum from one reel to the other reel.Type: GrantFiled: March 7, 2008Date of Patent: April 1, 2014Assignees: Korea Advanced Institute of Science and Technology, Sunam Co., Ltd.Inventors: Do-Jun Youm, Ja-Eun Yoo, Byoung-Su Lee, Sang-Moo Lee, Ye-Hyun Jung, Jae-Young Lee
