Title: Water purifier
Inventor: KIZAKI TADASHI
IPC: C02F1/28
Filed: 1987-03-25
Abstract: PURPOSE:To enhance water purification capacity by providing a packing press- contacted to a bag in the single side of a pressure-proof case and forming a through-hole to one part avoiding the outer periphery of the packing and enabling water filling into the bag. CONSTITUTION:Raw water is introduced through a water filling part 6 via a hose 7. At this time, raw water is purified in contact with a water purifying agent 5 of the inside of a bag 4 via the through-hole 10 of a packing 9. The purified raw water is discharged as clear water through a discharge port 3 and used for potable water or the like. For this operation, in case raw water is passed through the through-hole 10 of the packing 9, this packing 9 compresses the bag 4 to the direction of the discharge port 3 by water pass resistance. Further water pressure is exerted to the packing 9 from the raw water side and the bag 4 is strongly pushed to the direction of the discharge port 3. Thereby the bag 4 is closely stuck on the inner surface of a pressure- proof case 1 and water purification performance can be enhanced without causing leakage of raw water.

Title: Pulse counter
Inventor: MIZUHARA HIROHISA
IPC: H03K5/1252
Filed: 1982-04-22
Abstract: PURPOSE:To eliminate malfunctioning due to pulse-like noise by performing an integration and an equivalent operation with a digital circuit to allow the alteration of a program step utilizing the existing circuit as intact. CONSTITUTION:As soon as the program starts from the left end in the drawing, YES is given to a clock pulse 20a at the step 46, at the step 47, the level H is set at the current memory and NO is given at the step 48. The clock pulse 20a enters a subroutine 100 and when a timing pulse 20b comes, the level L is set as the memory temporarily at the step 41. With the subsequent timing pulse 20c, the level H is detected at the step 20c and at the step 44, NO given, calling for return to the step 40. As the level L is detected continuously n times after the passage by the rising point 22 of a waveform, the step is shifted from 46 to 50. With the judgement of YES at the step 50, 1 is added to a counting memory and the step is shifted to 49. Even with sampling pulses 20d-20f, the step 51 is reached with no exit from the subroutine 100 due to the judgement at the step 46, thereby making it equivalent to the elimination of noise form points 32-33.
