Abstract: PURPOSE: To biologically purify conc. waste water, which is beyond the boundary of an ordinary active sludge process, into purified water having sufficiently drainable quality without dilution, by subjecting the conc. waste water to treatment with undiluted high-load type bacteria and coagulating precipitation.  
     CONSTITUTION: Conc. waste water 1 having BOD above 1,000ppm or high nitrogen concentration, e.g. night soil, excretions of livestock or waste water from marine product-processing, is biologically purified during its passage through the first intrification vessel 2, the first denitrification vessel 3, the second nitrification vessel 4, the second denitrification vessel 5 and a deaeration vessel 6 into a precipitation vessel 7. A suspernatant liquid, i.e. undiluted purified water 12, in the precipitation vessel 7 is introduced into a coagulation separator 13, where a flocculant 14 is added to obtain purified water 15. As the flocculant is used aluminum sulfate or the like. Fine suspended solids exist in the suspernatant liquid 12 inside the precipitation vesssel 7, but the quality of the purified water can be improved by the application of said coagulating separation.

Title: Character processor
Inventor: HORI SUMIO
IPC: G06F3/0481
Filed: 1986-03-29
Abstract: PURPOSE:To simply attain the horizontal and vertical writing methods as well as the combination of both methods by setting previously a cursor in the prescribed shift direction in a document compiling mode and therefore securing an automatic shift of the cursor is response to the shift of the character input in said shift direction of the cursor. CONSTITUTION:The shift direction of a cursor is previously stored in a register CTR through a keyboard. If the input of characters is performed with the lower shift designated, it is decided that the contents of the cursor shift direction stored in the register CTR is defined as CTR = 2. Then it is decided whether or not a front cursor line address YCR is equal to the maximum digit number MAXY, i.e., whether the cursor can move downward or not. In case YCR not equal to MAXY is secured, '1' is added to the cursor line register UCR to move the cursor to a place lower by one line While it is decided whether a cursor digit register XCR is equal to 1 or not, e.g., whether the cursor can move to the left or not in case of YCR = MAXY. Hereafter the same procedure is repeated for each input of characters.

Title: Howling suppressing device
Inventor: FURUKAWA HIROMOTO
IPC: H04B3/21
Filed: 1984-04-09
Abstract: PURPOSE:To improve the howling suppressing effect by subtracting an estimated echo signal from a low frequency range component of an output of a super- directivity microhone and synthesizing a subtracted output and an output of a high pass filter. CONSTITUTION:After a signal I collected by the super-directivity microphone 18 passes through an amplifier 19, the signal is fed to an LPF22 and an HPF23. An output J of the LPF22 includes the voice of a talker and an echo signal from a speaker. Since the transfer function between the microphone and the speaker is estimated, an estimated echo signal Y is calculated by an echo signal estimating section 27 and after it is converted into an analog signal M, a signal K excluding the estimated echo signal M from the signal J including the echo signal at a subtraction section 30 is outputted. Thus, no echo signal is included in an output Q which is the synthesis (24) between the signal K and the output P of the HPF23 and howling hardly takes place.

Abstract: PURPOSE:To enable reduction of an inspection time, cost reduction and improvement of reliability by changing inspection items of following inspections based on measurement results for each inspection item of each semiconductor device in a series of electrical properties inspections which consist of a plurality of different inspection items. CONSTITUTION:At first, basic characteristics, that is, a threshold voltage, current amplification factor, a variety of resistance values, etc., of a transistor are inspected. According to inspection results thereof, inspection conditions for each functional test are decided, and ramified and performed ((b) to (e)). When following inspection results are also estimated from each inspection item, inspection conditions are modified and performed ((f) to (g)) corresponding thereto. Inspection conditions are decided to satisfy two points of sure discrimination of nondefective and defective items and minimum inspection time. For example, an inspection is made at a minimum of conditions according to results of a preceding inspection, or a functional test is made as quickly as possible or, on the contrary, a test is added. It is therefore possible to realize reduction of an average inspection time and reduction of inclusion of defective and to improve efficiency of an inspection by modifying inspection conditions of the same unit type according to its preceding inspection results.
