Title: Method for calculating parasitic resistance of fet
Inventor: INOUE TAKASHI
IPC: H01L21/66
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To evaluate a parasitic resistance accurately by rendering an FET a linear region and solving a related equation through the use of corresponding drain voltage and gate voltage being measured by varying the drain current under a constant gate voltage. SOLUTION: A Schottky gate FET is rendered a linear region by applying a constant drain bias voltage under common source state and then corresponding drain voltage Vd and gate voltage Vg are measured by varying the drain current Id under a constant gate current Ig. A specific mathematical expression is established between the source parasitic resistance Rs and the drain parasitic resistance Rd . Based on the numerical difference of the Rd and Rs determined from the inclination of gate current Vg vs gate current Ig curve at the time of drain open and source open, the mathematical expression is solved through numeric analysis thus determining the source parasitic resistance Rs . The drain parasitic resistance Rd is also determined simultaneously. Required measurements can be performed by means of a semiconductor parameter analyzer.

IPC: F23D11/10
Filed: 1984-08-29
Abstract: PURPOSE:To increase safety in an oil burner of evaporation type, by providing a device to prevent the temperature from exceeding in a position separated from a burner body, in addition to a temperature detector which detects the temperature in the side walls of an evaporation chamber and to control supplying of power to an electric heater. CONSTITUTION:When an electric heater 7 is energized and a burner body 2 is heated, the temperature in the side walls 5 of an evaporation chamber in a burner body 2 is raised to the evaporatable temperature of about 230 deg.C. Then liquid fuel is fed to be evaporated in an evaporation chamber 4, and evaporated gas and combustion air are premixed to perform gasifying combustion with blue flames. Following the progress of combustion, the temperature in the side walls 5 of an evaporation chamber is raised further up to about 260 deg.C. At about this temperature, a thermister 19 is actuated to stop supplying of power to the electric heater 7. When the thermister 19 fails caused by broken wire or other, the electric heater is continuously energized and the temperature in a burner body 2 is kept rising higher than the predetermined 260 deg.C. But about this time, the heat is transmitted to a heat conductive plate 20 through the buried part 6 of a heater, and a device 22 to prevent the temperature from exceeding senses the heat to stop supplying of power to the electric heater 7.

Abstract: PURPOSE:To attain the high integration and the low consumption of power by controlling the bias voltage on the back of board by the output from level detector circuit when the absolute level of bias voltage at the back of board has become to a predetermined value. CONSTITUTION:When a RAM is subjected under non-selective condition of chips, the output of a gate circuit G1 corresponds to the output from the level detector circuit. When the absolute value of bias voltage at the back of board is smaller than the total threshold voltage 3Vth from Q12-Q14 for MOSFET, Q12-Q14 are turned to OFF and the detected output is turned to the high level. An oscillator circuit OCS1 performs the oscillation by the high level of a circuit G1 to increase the absolute value of voltage -Vbb. When the absolute value of voltage -Vbb exceeds voltage of 3Vth, Q12-Q14 are turned to ON to provide a detection output of high level through the circuit G1. When the output is ON, the low level and the outputs from circuits G2-G4 for oscillation circuit OSC1 are turned to high levels, the oscillation is stopped.
