Title: Treatment of polyphosphoric acid-containing waste water
Inventor: ASANO HIDEYUKI
IPC: C02F3/34
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To perform flocculation treatment in the post-stage of waste water treatment without hindrance by bringing waste water containing polyphosphoric acid into contact with bacteria under a specific pH condition to decompose polyphosphoric acid. SOLUTION: Waste water to be treated is supplied to a tank 1 from inflow piping 2 and bacteria necessary for hydrolysis are supplied to the tank 1 from a bacteria supply line 3 to stirr waste water by a stirrer 4. In this case, the pH of waste water is set to 4.5-6.0 and waste water is brought into contact with bacteria under this condition to hydrolyze polyphosphoric acid to orthophosphoric acid. This treatment may be performed batchwise or continuously. As bacteria, activated sludge generated by the treatment of sewage can be used. In order to immobilize bacteria, a fixed bed system or a fluidized bed system may be used. Further, bacteria may be held to a floating state. Stirring may be performed by blowing gas such as air into waste water.  By this constitution, a flocculation optimum pH range becomes wide and the flocculation treatment of treated water after treatment becomes easy and post-stage treatment is performed without fear of hindrance.

IPC: G01R33/04
Filed: 1981-06-03
Abstract: PURPOSE:To obtain stable operation and to improve the precision of magnetic field measurement, by composing a phase shifting circuit of a digital circuit. CONSTITUTION:When the signal f0 of an oscillator 6 has a waveform as shown by (a), a frequency dividing circuit 12 divides the frequency of the signal f0 and outputs a signal fR having a waveform as shown by (b). A flio-flop 13 is connected on binary basis, so when the signal fR has a high level and the signal f0 is inputted, the state is inverted to output a waveform fD shown by (c). Thus, the rising phase of the signals f0 and fR coincide with each other, and they never shift owing to fluctuations of temperature, etc. The output of this circuit is supplied as the energizing signal of a magnetic sensor and used as a reference signal for phase detection, thereby obtaining a high-precision magnetic field measuring device which performs stable operation.

Abstract: PURPOSE: To improve flexibility of a tube, by a method wherein a bellows type or a spiral type synthetic resin made flexible tube compressed to a contractive limit  in the axial direction is stretched at the normal temperature after it is heat-treated,  and a tensile force is released.  
     CONSTITUTION: A bellows type or a spiral type synthetic resin made flexible tube molded by a conventional blow-molding method is stretched in the axial direction  to a contractive limit, and with this the tube is heat-treated. The tube so treated is  stretched at room temperature, and is then released. For example, the synthetic  resin made bellows type tube with a length of 294mm obtained by a blow-molding  method is compressed in the axial direction of the tube to the contractive limit, and  with this tube is immersed in hot water having 100°C. The tube is then restored to  room temperature, and is stretched to about its former length. The resultant tube is  then released from a tensile force to obtain a flexible tube, with a length of 175mm  being excellent in the flexibility.

Title: Direct monitoring device for frequency characteristic with quality deciding function
Inventor: KUMAZAWA SHINICHI
IPC: G01R13/30
Filed: 1980-06-27
Abstract: PURPOSE:To provide a device which is caused to draw a frequency characteristic curve of an object to be measured on a CRT tube together with a reference line of a level, that forms a reference of a measurement, and of a frequency, and enables to perform an automatic decision of the quality. CONSTITUTION:A spot-reference frame generating part 8 consists of a X side multiplexer 9 and a Y side multiplexer 10 having individually 4-input. Spot indicating inputs X1, Y1, a level reference line lamp wave signal X2, a frequency reference line lamp wave signal Y3, upper limit level signals X3, Y2, lower limit level signals X4, Y4 are sent to each input, and are changed over by means of a sequence controller 17 to be sent to an indicating circuit. In a quality decision part 21, a X side comparator 22 compares the X1 with the X3 and X4, and a Y side comparator compares the Y1 with the Y2 and Y4. As a result, if the input exceeds the upper and the lower limit within a frequency range previously set, a D-FF28 or 29 is triggered, and as a result, an indication lamp 36 or 38 is lighted. Thus, the quality of the frequency characteristic can be decided without visually watching over a CRT.

Title: Vaccine and manufacture
Inventor: DENISU ERU KASUPAA
IPC: C12P19/26
Filed: 1981-06-09
Abstract: Culturing Streptococcus agalactiae in a nutrient broth containing at least 10g/l of glucose while maintaining the pH at 6-8 by the addition of alkaline material produces polysaccharide antigen including a fraction having a molecular size from 8-11 x 10<5>d. By employing a broth free from constituents having a molecular size above 10<5>, the antigens can be separated from the broth in high yield after harvesting the organisms. Vaccination of humans with Streptococcus agalactiae polysaccharide antigens having molecular sizes above 5 x 10<5> produces in selected individuals specific antibody levels above 200  mu g/ml of antisera; globulins fractionated from such antisera contain most of the antibody and can be used for passive immunization.

Title: Method of detecting overload of motor
Inventor: KAWAKURA TAKAYUKI
IPC: B60J1/17
Filed: 1994-03-31
Abstract: PURPOSE:To detect a constant overload at all times without being subject to the effect of the magnitude of applied voltage by discriminating load as overload when pulses are not generated next before a timer interrupt time passes after the time of the preceding generation of pulses. CONSTITUTION:When an interrupt signal is generated at an earlier time than pulses are generated, a period tn+1 based on the current generation of pulses is measured at the step ST6, and a step ST7 is returned to a step ST3 while using the period tn+1 as a pre-period tn in the next cycle at the step ST7. When current pulses are not generated when the interrupt signal is generated, load fluctuation reaches an overload level, and a step ST5 proceeds to a step ST8. Accordingly, the measured period is compared with a discriminating value multiplied by a coefficient read on the basis of a pre-period measured at a time before by one step and the pre-period from prepared map data, and overload is discriminated, thus allowing the detection of overload not affected by the fluctuation of the applied voltage of a motor.

The electromagnetic conversion characteristic of a high level is obtd. by using two kinds of such CBs together with the above-mentioned magnetic metal powder. 1X10<9>OMEGA/sq specific surface resistance is obtd.; dust is hardly stickable to the magnetic medium and the drop-outs are decreased. The coefft. of friction of the magnetic layer surface is lowered and the excellent running durability is obtd. Since the coefft. of dynamic friction is low, the powder dislodging at the time of repetitive running is suppressed and the good running at and under the high temp. and high humidity is attained.
