Abstract: PROBLEM TO BE SOLVED: To decrease flickers without lowering a contrast ratio even at a high temp. by disposing a first electrode and a second electrode which is arranged opposite to this first electrode via a light insulating film and is formed of the same material as the material of the gate electrode of a thin-film transistor. SOLUTION: The dependency of a MOS capacitor 88 of a P channel on gate voltage is symmetrical with the case of an N channel and attains C0 in gate voltage VG<threshold voltage Vth and Cgso in VG>Vth. Then, VG<Vth in an ordinary state that the TFT is turned off and, therefore, all the superposed areas of an electrode 88 and scanning line 84 act as the electrode of the capacitance and the intrinsic MOS capacitance C0 is eventually added. The magnitude of the capacitance is about 100 to 20% of the capacitance of the liquid crystals driven by a pixel electrode 86 and is considerably large. In the period when the scanning line 84 of the previous stage is selected, the MOS capacitor is turned off and only the superposed capacitance Cgso is attained and, therefore, the waveform of the scanning line is not made dull and the change in the driving state is averted by adding the capacitance.

Title: Hydraulic machine
Inventor: SATOU SHINSAKU
IPC: F03B3/12
Filed: 1983-10-17
Abstract: PURPOSE:To make it possible to adjust and reduce the hydraulic axial thrust working on a runner in a hydraulic machine for hydroelectric power generation by leading a water flow smoothly from a runner back pressure chamber to a low pressure chamber downstream of the runner. CONSTITUTION:In a runner cone chamber 10, the water pressure distribution goes up from the lower end toward the outward because of a centrifugal force caused by the rotation, and a balance hole 11 is set up in such a manner that an opening D1 will be placed in the area free of that effect; thus the pressure difference between the inlet and outlet ports becomes large and the water flow increases. And, when the area of the lower end opening D2 of a runner cone 8 is made larger than the total sum of cross-sectional areas of each balance hole 11, a reasonable construction will be realized. Thus a water flow is smoothly led from a runner back pressure chamber 7 to the low pressure side downstream of a runner vane 1 through each balance hole 11, making it possible to adjust the water pressure distribution in the runner back pressure chamber 7. In this way, the hydraulic axial thrust working on a runner 1 can be adjusted and reduced.
