Inventor: FUKUNAGA MINORU
IPC: B01D24/46
Filed: 1977-11-11
Abstract: PURPOSE: To  operate the filtration of raw water and at the same time to clean the filtration material by constructing a filtration tower as a part of a syphone, without using motive force.  
     CONSTITUTION: Open valve 6, close valve 9 and fill filtration tower 1 with raw water from raw water tank 4 by driving vacuum pump 2. Next, stop the operation of vacuum pump 2. Then, open valve 9. Filtration is operated as raw water is fed from filtration tower 1 into processing tank 7 by syphone action. When the pressure heads of raw water tank 4 and processing tank 7m are balanced, the filtration stops automatically. As a result, by closing valve 9 of processing water pipe 8 and opening valve 12 of cleaning water discharge pipe 11, the water level difference between raw water tank 4 and cleaning-water discharge tank 10 gives rise to syphon action and the water flows from filtration tower 1 to cleaning-water discharge tank 10 and thereby filtration material 3 is cleaned.

Title: Digital oscilloscope
Inventor: FUJISAKI HISASHI
IPC: G01R13/20
Filed: 1987-05-29
Abstract: PURPOSE:To display the envelope of an input signal even by slow sweeping by sampling an observation signal at time corresponding to a random phase. CONSTITUTION:The observation signal from an input terminal IN is sampled and held 2 through an amplifier 1 and its amplitude is converted by an A/D converter 3 into a digital value, which is stored in a memory 7. When the sampling time from a clock generator 4 is reported to a sampling clock generator 6, the generator 6 generates a sampling clock delayed by time based upon a random signal from a random signal generator 5 and supplies it to a circuit 2. Further, the generator 4 supplies the sampling time as an address of the memory 7 and a waveform display part 8 displays a waveform by setting the amplitude digital value of data stored in the memory 7 on a vertical axis V and the address on a horizontal axis H. Therefore, when the input signal period is smaller than the sampling period, the input signal can be sampled at time corresponding to a random phase, so the envelope of the input signal can be displayed even by slow sweeping.
