Title: Secondary excitation control system for induction machine
Inventor: KITABAYASHI YUKIO
IPC: H02P23/07
Filed: 1984-12-11
Abstract: PURPOSE:To improve the power factor of a power source side by amplitude- modulating the secondary current synchronously with the secondary induced electromotive force to control the secondary current waveform of an induction machine, thereby arbitrarily controlling the power factor of the machine. CONSTITUTION:The secondary current waveform instructing circuit 15 inputs the secondary voltage V2 generated in the secondary widing of an induction machine to generates the secondary current command I2d synchronized with the secondary voltage. A comparator 17 compares the command I2d with an absolute value signal 1 ¦I2¦ obtained at the output of a current detector 12, and thereby outputs a DC current. When a GTO3 is turned ON, a DC current thereby increases, and magnetic energy stored in the circuit in which the current is flowed increases. When the GTO3 is then turned OFF, the energy is discharged to charge a capacitor 5. Since an inverter 6 is controlled in the constant firing phase, the power factor can be always held at the prescribed high value.

Title: Field effect transistor and manufacture thereof
Inventor: YOSHIDA NAOTO
IPC: H01L21/335
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain a field effect transistor adapted to make it possible to perform the high frequency, high gain and high efficiency operation and to a high output operation and a method for manufacturing the transistor. SOLUTION: A channel layer 100 is formed of an i-type InGaAs channel upper layer 6 provided at a gate electrode side and an n-type GaAs channel lower layer 55 provided at a GaAs substrate 1 side. Thus, since the layer 55 serves as a main current route at the gate electrode 11 at the time of applying a high drain voltage, a collision ionization at the layer is suppressed, and the breakdown voltage of the channel can be increased. Further, since both the layer 6 and the layer 55 serve as main current routes between the source and the gate, low source resistance is obtained to make it possible to perform the high frequency, high gain and high efficiency operation.

The opening degree of the steam governor valve 2 is made smaller than the ordinary operation value by increasing the main steam pressure characteristic higher than the ordinary operation value during the steam turbine stop process. Accordingly, the throttle effect of the steam governor valve 2 is improved, and the temperature of the steam which is expanded after passing through the steam governor valve 2 is lowered. Accordingly, the steam whose temperature is lowered is introduced into the steam turbine 3, and the metal temperature of the steam turbine 3 is lowered.
