Company Background: Samsung Electronics Samsung Electronics was established in 1969 in order to provide an engine of future growth for the Samsung Group. Though the electronics industry seemed promising in the 1960s‚ none of the Korean firms had advanced technology. Samsung began by producing low-end black–and-white televisions in a joint venture with Sanyo‚ a Japanese electronics company. With NEC‚ another Japanese firm‚ it produced Braun tubes and kinescope tubes. After three years‚ it began

POT TENDING MACHINE PTM is the crucial equipment of large anode pre-baking workshop. It is used in the environment of high temperature‚ large current‚ strong magnetic field and HF gas. It can perform the following procedures ANODE CHANGE: Anode in the pots is changed at an interval of every 27 days since daily 1.5 cm of the anode gets consumed. A carbon block is usually 55 cm high of which only 40 cm can be used up. The main reason behind the anode consumption is the following electrolytic

1.) How gating of a thyristor works? A thyristor is a 4 layer 3 terminal device with 3 junctions. When the anode terminal has positive voltage and no gate voltage is applied‚ the first and the third junction are forward biased and the second junction is turned reverse biased allowing no current flow through the thyristor. A thyristor starts to conduct when the voltage across the anode and cathode (VAK) is increased beyond the thyristors breakdown voltage (VBO). This is
