Title: Treatment of heavy metal-containing drain by sulfur reduction
Inventor: MAJIMA MICHIO
IPC: C02F1/70
Filed: 1986-06-19
Abstract: PURPOSE:To easily treat waste water, by adding sulfurs powder and a reducing agent to heavy metal-containing drain to form heavy metal sulfide as precipitate and removing said precipitate. CONSTITUTION:Sulfur powder is added to heavy metal-containing drain containing a heavy metal such as mercury or copper in an amount of 2.5g or more per 1l of drain and about 1.5g of iron oxalate being a reducing agent of sulfur hardly soluble in water is added to drain to reduce sulfur into sulfide ions. The heavy metal is converted to sulfide to form a precipitate and this treatment liquid is separated into the precipitate and the liquid. By this method, the heavy metal in drain can be removed so as to be less than the drain standard.

Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To deal with a high carrier frequency at a low cost and to widen the modulation band by multiplexing an optical carrier demultiplexed with a wavelength filter with a frequency modulated optical sub-carrier outputted from an optical frequency shifter. SOLUTION: Two waves adjacent at a 60 GHz interval of a laser beam from a mode lock laser diode(MLLD) 1 are cut out by an array waveguide diffraction grating(AWG) 2. An emission beam from a fiber collimator 3a is made incident on an acoustooptical modulator(AOM) 4 as a parallel beam. A modulator 13 applies an output of an oscillator 11 to the AOM 4 when a digital signal is '1', and doesn't output when '0'. The optical sub-carriers transmitted or diffracted by the AOM 4 to be frequency modulated are made incident on a 3 to 1 coupler 6 respectively through the fiber collimators 3b, 3c. The 3 to 1 coupler 6 multiplexes the optical carrier of an optical frequency f0 demultiplexed by the AWG 2 with the optical sub-carrier of the optical frequencies f1 (f2) frequency modulated by the AOM 4 to output it.

Abstract: PURPOSE:To eliminate a factor to the deterioration in the processing ability of the software, by constituting a monitor circuit having two kinds of signal recognizing time and its switching circuit with the hardware so as to decrease the number of interfaces. CONSTITUTION:In receiving a command transmitting an SZ signal F1 from a controller to an opposite exhange at a signal transceiver 102 via a lead 203, the F1 signal SZ is transmitted to the opposite exchange via a line 202 and applied to a double supplemental detecting circuit 104, which monitors the F1 signal from the opposite party via the line 202.

The controller stops the transmission of the F1 signal. When the device idle state detecting circuit 103 detects the stop of the F2 signal at a lead 205, the circuit 103 discriminates that the device is busy, the F1+F2 signal is received and the stop of signal is detected, then it is discriminated as the device idle state.

A marking 11 is applied to two points of a specified parts of the scanoimage. At a surface image processing section 9 where the surface image of the object 2 to be inspected is formed, the position of the marking 11 of the scanoimage is determined, based on a moving speed of a bed 1 and the interval L between a gantry 3 and a line sensor 7, and the marking 11 is applied to the same part of the surface image. Then, an image creating section 10 performs a combining of both the images so as to make the positions of the markings 11 match each other and creates a composite image. This allows an operator to determine a section imaging part of the object 2 to be inspected, referring to the synthetic image thus obtained, thereby enabling the better setting of the section imaging part constantly.

The blade 5 is retreated while being slid on the bottom surface of an upper plate 6. A held glass on the blade 5 is pushed with the tip part 7 of the upper plate 6, and fed into the center of the mold 3 to form a glass gob 10. Glass 11 stuck to the tip part 7 of the upper plate 6 is removed by advancing a platelike member 9 to rub the tip part 7 of the upper plate 6. According to the above-mentioned method, the molten glass gob 10 having a low viscosity can be smoothly molded, and the exchange of the mold 3 can be carried out without disturbing the glass stream 2.
