Patent number: 9651577Abstract: A pogo pin may include a housing, a resilient connecting member and a switching unit. The housing may be arranged between a printed circuit board (PCB) and a probing head. The resilient connecting member may be arranged in the housing to electrically connect the PCB with the probing head. The switching unit may be provided in the housing to selectively cut off an electrical connection between the PCB and the probing head. Thus, because the PCB may not require additional switching substrates, the PCB may have a small size so that the probe card may also have a small size. A semiconductor device may be manufactured using the probe card.Type: GrantFiled: August 29, 2014Date of Patent: May 16, 2017Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Sung-Ho Joo, Yu-Kyum Kim, Joon-Yeon Kim

Publication number: 20120100497Abstract: The present invention relates to a burner using plasma, which uses a mixture fuel in which water and industrial waste oil are mixed at an appropriate ratio. A combustion tank has a positive electrode (+), a rod installed at one side of the combustion tank has a negative electrode (?), and direct current electricity is supplied to the combustion tank and to the rod from a direct current electricity supply unit. A steam supply pipe of a steam generator is installed together with a plasma torch unit which is coupled to the combustion tank, such that high-temperature steam is discharged from the steam supply pipe together with the plasma torch generated by the plasma torch unit. Thus, the high-temperature plasma torch generates a high-temperature plasma flame of 800° C. or higher to heat a combustion chamber at the inner wall of the combustion tank.Type: ApplicationFiled: June 22, 2010Publication date: April 26, 2012Inventor: Sung Ho Joo
