Title: Measuring apparatus
Inventor: MIZUGUCHI HIROSHI
IPC: G01R29/027
Filed: 1982-05-07
Abstract: PURPOSE:To prevent malfunctioning by prohibiting the resetting of FFs during the rewriting of a memory for storing a measurement output for a measuring apparatus having the period of an active level depending on displacement of two inputs. CONSTITUTION:First and second input signals are applied to a preset signal input terminal PR and load signal input terminal LD. When the counting cycle of a counter 100 to which a first clock pulse applied to a clock pulse input terminal CL1 is longer than that of the first signal, the output terminal of a memory 200 obtains a value depending on a phase difference between the first and second signals. When the output of the memory 200 and the output of the second counter 300 coincide, a comparator 450 resets an FF54. This keeps an AND gate 55 from producing an output regardless of any malfunctioning by the comparator 450 during the loading of the memory 200. Thus, the FF54 won't be reset.

Title: Method and apparatus for treating wastewater containing organic solid
Inventor: KOBAYASHI KAZUO
IPC: C02F3/02
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for treating wastewater containing organic solids whereby treated water having good qualities is obtained; the treating capacity is stabilized; and the apparatus can be small-sized by separating the wastewater by solid-liquid separation with a filtration membrane into organic solids and membrane-filtered water and subjecting the solids and filtered water individually to a biological treatment in different aerobic treatment vessels. SOLUTION: When wastewater containing organic solids flows through a wastewater flow-in pipe 111 as indicated by the arrow (a) into a solids treatment vessel 12, the water level in the solids treatment vessel 12 rises and the solid-liquid separation of the wastewater is carried out with a flat membrane unit 122 by the water head due to the difference in water level from the outlet of a membrane-filtered water flow-out pipe 114.  The membrane-filtered water is transported through the membrane-filtered water flow-out pipe 114 into a membrane- filtered water treatment vessel 13, wherein the inside atmosphere is kept aerobic by the air jetting out from an air diffusion apparatus 117, and the membrane-filtered water is subjected to a biological treatment with a sludge attached to a contact material 119 under continuous stirring without allowing the solids to stagnate by installing an inclined sidewall in the vessel 13. Thus treated water is discharged by overflow as indicates by the arrow (b) through a treated water discharge pipe 112.
