Filed: 1982-03-26
Abstract: PURPOSE:To make contact resistance of an ohmic electrode to be reduced by a method wherein a low resistivity layer is formed at the lower part of the ohmic electrode using a doped oxide film. CONSTITUTION:The Sn doped SiO2 film 5 is applied using a spinner on a GaAs FET wafer 1 at first. Then patterning is performed leaving the SiO2 film 5 only at the parts to constitute source and drain electrodes 2, 3 according to photoengraving technique and etching. Moreover annealing is performed in an H2 atmosphere at 800-1,000 deg.C for 10-60min to form an N type low resistivity layers 6 only at the lower parts of the source and drain electrodes 2, 3. Contact resistance of the ohmic electrode depends upon carrier concentration of the semiconductor coming in contact with the ohmic electrode material, and the higher carrier concentration is, the lower contact resistance becomes.

Title: High sped valve controller for turbine
Inventor: SUGIMOTO HIROSHI
IPC: F01K7/24
Filed: 1986-03-07
Abstract: PURPOSE:To suppress the pressure rise of steam in a reheater, to prevent the step out of a generator and to suppress the fluctuation of the generator output by constructing such that a fault on a transmission line is detected and open/ close control signals are fed only to a part of plural intercept valves. CONSTITUTION:Upon occurrence of a fault on a transmission line, a high speed valve control circuit 81 for turbine functions to provide an open/close command to an intercept valve 7A (or 7B). Abrupt closure of the valve 7A (or 7B) causes abrupt decrease of the steam flow from a reheater 2 to a low pressure turbine 3A (or 3B) thereby the sum of the output from a high pressure turbine 1 and the outputs from the low pressure turbines 3A, 3B decreases abruptly as shown by a curve T, but the decreasing rate is sufficiently low corresponding to the amount which is not controlled conventionally. The pressure of steam in the reheater 2 does not rise abruptly because only one of the outlet conduits is closed by means of the valve 7A (or 7B). Here, the output from the generator 4 has a relatively low amplitude as shown by a curve G.
