Publication number: 20210394281Abstract: Disclosed are a drill and an insert for a drill having improved centering capability and cutting performance. In the drill of the present disclosure, central relief surfaces of cutting parts are processed as flat relief surfaces, and outer circumferential relief surfaces continuing from the center part to the outer circumferential surface of the drill are processed as curved relief surfaces, thereby enhancing the centering capability of the drill and minimizing the generation of drill vibration and burrs. In addition, in the drill of the present disclosure, the outer relief surfaces of the drill in contact with a hole to be drilled are processed such that an angle between the tangential lines of the outer relief surfaces is constant regardless of the size of the outer diameter of the drill, thereby achieving consistent performance of the drill despite change in the outer diameter of the drill.Type: ApplicationFiled: September 18, 2019Publication date: December 23, 2021Applicant: YG-1 CO., LTD.Inventors: Young Koon PARK, Jung Wook LEE

Publication number: 20200254538Abstract: An end mill having an eccentric flat relief formed thereon is proposed. The eccentric flat relief (simply referred to as “ELF”) includes at least three flat relief surfaces continuously arranged along a trajectory of an eccentric relief. Accordingly, the end mill, which combines strengths of the flat relief and an eccentric relief, has excellent rigidity and a heat discharge characteristic.Type: ApplicationFiled: October 17, 2019Publication date: August 13, 2020Applicant: YG-1 Co., Ltd.Inventors: Young Koon Park, Hyung Suk KIM, Seung Hyun LEE

Patent number: 7238170Abstract: This invention prevents the danger of falling of body temperature by making the blood temperature similar to the body temperature in the injection of Ringer's solution fluid or blood transfusion, and also alleviates the patient's pain and improves the speed at which Ringer's solution fluid or blood enters the body. The warming device is much cheaper than previously released products, and small and light in weight, and allows blood or solution fluids to flow most effectively by allowing sufficient time for heat transfer as a pack type. The operation is convenient and sanitary in its single usage only. The inventive purpose has the methods of utilizing the temperature sensor in adjusting temperature by utilizing them PTC heating element's resistance specialty against the temperature as well as temperature sensor.Type: GrantFiled: April 7, 2001Date of Patent: July 3, 2007Inventor: Koon Park
