Title: Francis turbine
IPC: F03B3/02
Filed: 1992-03-30
Abstract: PURPOSE:To set the max. efficiency point of a waterwheel at an optimum fall position of the efficiency characteristic by shifting the cavitation generation region on the runner blade inlet negative pressure surface which is generated on the high fall side, to the high fall side. CONSTITUTION:A plurality of guide blades 9 are projectingly installed on the flowing water surface of a lower cover 3 positioned between a movable guide vane 5 and a runner blade 6b. These guide blades 9 reduce the incident angle for the runner blade inlet by deflecting the water stream directing to the vicinity of a runner band 6c among the high pressure water which flows out from the guide vane 5, to the radial direction side, and suppress the generation of cavitation on the runner blade inlet negative pressure surface.

Title: Semiconductor integrated circuit
Inventor: ITO KUNIHARU
IPC: H01L27/092
Filed: 1986-03-31
Abstract: PURPOSE:To eliminate the through-current of an output and to reduce the current consumption of the circuit by providing a delay circuit and the 1st and 2nd logic circuits, generating a signal driving each of an N-channel transistor (TR) and a P-channel TR. CONSTITUTION:When an input signal at an input terminal 1 changes from L to H, an output waveform of a NOR gate 6 changes from H to L at first and an output waveform of an inverter 7 changes from L to H, the P-channel TR 10 is turned off. On the other hand, the output wa veform oa a NAND gate 8 changes from L to H by the output waveform of the delay circuit comprising inverters 2, 3, 4, 5 to change the output waveform of the inverter 9 from L to H with a delay from the output waveform of the inverter 7 to turn on the N-channel TR 11. Conversely, since the output waveform of the ivnerter 9 changes from H to L in the change from H to L before the output waveform of the inverter 7, the TR 10 is turned on after the TR ll is turned off. In both the cases, after one TR is turned off, the other TR is turned on and no through- current flows.
