    摘要： A digital code conversion system in a magnetic recording apparatus for converting one bit of an input digital signal into a signal of two bits, in which the number of binary digits of "0" making appearance between adjacent binary digits of "1" is two at minimum and seven at maximum. In the digital code resulting from the code conversion, ratio between maximum and minimum values of the density at which the binary digit of "1" makes appearance is 1:2.

    摘要： Developer-containing waste water is subjected to a multi-stage biological treatment. A waste water treatment apparatus for carrying out a two-stage biological treatment has an adjustment tank for receiving raw waste water and for preliminarily adjusting water quality of the waste water. First and second contact aeration tanks are used to biologically treat the waste water. First and second settling tanks are connected to the first and second contact aeration tanks for separating by sedimentation sludge from the waste water. Specifically, the first settling tank is connected to the second contact aeration tank. Sludge separated from the waste water is returned from the first and second settling tanks to first and second mixing tanks, respectively, and mixed with Bacillus Subtilis Kubota (BSK) and excess household sludge. The mixture is aerated and then transferred to the first and second contact aeration tanks, respectively. The aerated mixture in the first mixing tank is also transferred to the adjustment tank in accordance with the water quality of the raw waste water.

    摘要： A method and apparatus for wastewater treatment is provided which can treat persistent surface active agents and coloring substances in wastewater, and which is compact and economical. The wastewater treatment method introduces water to be treated into a charcoal tank 3 packed with charcoal 10 and treats the water therein, the water to be treated having been pretreated in a pretreatment section 2. The water under treatment is introduced from the charcoal tank 3 into an activated carbon tower 6 packed with activated carbon 17 to treat the water therein. Treatment of the water in two stages, namely, treatment by bioactivated charcoal 10 and treatment by bioactivated carbon 17, makes it unnecessary to carry out backwashing of the activated carbon tower 6 and regeneration of activated carbon 17. The service life of the activated carbon can be greatly extended.
