Title: Flotation method of solids contained in sewage sludge or the like
Inventor: ITOU HAJIME
IPC: C02F1/24
Filed: 1980-08-30
Abstract: PURPOSE: To perform flotation of solids contained in sewage sludge or the like by removing the coarse air bubbles in the air bubbles formed in a frothing device, and using the bubble water contg. only the fine bubbles for flotation.  
     CONSTITUTION: The treating water supplied into a coarse bubble separating tank 8 is fed into an inline mixer 10, where it is given shearing force and the air sucked simultaneously with the sucked water is fined, after which it is supplied to the lower part of a coarse bubble separating tank 8. The large bubbles in these bubbles are high in floating speed and annihilate by ascending quickly to the water surface. The fine bubbles held floated in the tank 8 flow over a partition plate 9 down into a bubble water discharge chamber B, from the lower part of which is supplied via a bubble water supply pipe 11 into a sewage sludge supply pipe 2, where it is  mixed with sewage sludge or the like. Thereafter, it is charged into a flotation tank  1. In the tank 1, the solids in the sewage sludge stick to the uniform fine bubbles  and float. The floated and separated solids are easily removed by a scum scraper 4  and the like.

Abstract: PURPOSE:To feed a sheet of paper from such a paper feeding part where a paper jam is hard to occur by installing a paper detecting means capable of detecting any paper jam individually in each conveying passage of plural numbers of paper feeding parts. CONSTITUTION:When an upper stage cassette 151 is selected, first whether there is each cassette of the same size in other stages 152, 201 or not is judged on the basis of output of a paper size detecting sensor, and if there is the same size cassette in another stage, sizes of the jam count value stored in each specified area of a random access memory (RAM) are compared. If the jam count value of the upper stage cassette 151 is larger than that of the other stage, the other stage cassette, where the same size paper is housed, is selected and paper feeding takes place. Afterward, when a copy start key is pushed, and a paper feeding jam is detected by a paper detecting sensor 158, the jam count value in the paper feeding stage where the jam has occurred addes one, and then a sheet of paper is fed out of the other cassette where the same size paper is housed, thus copying is carried out.

Filed: 1977-10-08
Abstract: PURPOSE: To shorten the time required for production of the operand address, by constituting the readout output of register to a specific value, when the specific bit of instruction has a given value.  
     CONSTITUTION: The all zero described in the B and X field of the macroinstruction 50 represents the disuse of the field corresponded, then the logical 1 is written in the specific bit P of the microinstruction stored in the microinstruction storing register 8. When  the entried values B and X are read out from the address designation register 1, the zero discriminating circuit 2 outputs logical 1 to the signal line 4, and AND circuit 10 outputs 11 entirely logical 0. Further, the bit P is logical 0, then the output 7 of the conventional register 9 designated with the address information line 3 is appeared at the output line 11 as it is. Thus, when the register 9 is designated with the values B, X, the displacement D is added to the value obtained from the output 11, then the operand address is developed. Further, the time required for the production can be shortened
