Title: Multistage hydraulic machine
Inventor: HISHIDA YASUO
IPC: F03B3/18
Filed: 1980-01-21
Abstract: PURPOSE: To enable the racing start of a multistage hydraulic machine and reduce the starting torque, by providing a seal mechanism for the uppermost-stage movable guide vanes and introducing compressed air into a pump runner chamber at the starting to push down the level of water.  
     CONSTITUTION: A seal member 20 made of an elastic material is provided between the first-stage movable guide vane 9 and an upper and a lower covers to attain tightness against water. Clearances A, B are defined on the second-stage and other  guide vanes 10, 11 at the time of closing operation. When compressed air is introduced through an air supply pipe 17 at starting, the level of water is pushed down toward a vane flow passage 6 because of the first-stage movable guide vane seal 20. The level of water further falls to a draft tube 8 through the clearances A, B. For that readon, each stage runner is exposed to the air to enable racing start. This results in reducing the starting torque and providing a simple and reliable mechanism.

Abstract: PURPOSE:To reduce circuitry and to reduce the timing jitter by providing a sampling circuit which takes the signal of each subchannel passing each delay circuit as the input and synchronizes respective subchannels at a generated single symbol timing. CONSTITUTION:Base band signals 7 outputted from a subchannel separating circuit 2 are delayed in delay circuits 11 by prescribed extents to output respective signals 13 whose symbol timings(St) coincide with each other. Level conversion circuits 12 convert the signals 13 by respective prescribed values, and signals 14 converted to certain values are inputted to an St estimating circuit 3c and a sampling circuit 4b. The circuit 3c uses the timing St and all of signals 14 to estimate the timing and eliminates the jitter to output a timing signal bb. The circuit 4b samples signals of four subchannels at the same timing in accordance with the signal 8b. Thus, tone circuit scale is reduced, and the timing jitter is reduced to correctly synchronize the subchannels.

Abstract: PURPOSE: To enhance vibration damping ability higher than in the conventional vibration damping plate further to increase also damping a specific frequency by laminating a damping material into two layers, and providing a plurality of recessed parts in a side of fixing the one damping material. CONSTITUTION: Since volume modulus in a plurality of columnar recessed part 4, provided in a side of fixing a damping material 3 molded in a sheet shape, is decreased smaller than a damping material 2, 3 itself, a plurality of the columnar recessed parts 4 are violently contracted and expanded by a sound pressure. A sound wave is scattered by vibration due to these contraction/ expansion, and by dispersing partly sound wave energy to disappear, damping a progressive wave is increased. By different acoustic impedance, the sound wave is partly reflected in a boundary surface. Further by having a natural frequency in a plurality of the columnar recessed parts 4 by themselves, a plurality of these columnar recessed parts 4 by themselves perform working as a dynamic absorber. Accordingly, damping a specific frequency can be increased.
