Abstract: PURPOSE:To obtain the titled magnetic powder excellent in the dispersion properties and the packing properties by allowing ferric salt to react with alkali in the presence of oxyalkylamine, subjecting the produced ferric hydroxide to the hydrothermal treatment to produce discoid alpha-FeOOH and reducing it. CONSTITUTION:Ferric salt (e.g. ferric chloride) is allowed to react with alkali (e.g. NaOH) in an aq. medium in the presence of oxyalkylamine )e.g. monoethanolamine) to produce ferric hydroxide. Then the slurry of ferric hydroxide is subjected to the hydrothermal treatment to obtain discoid alpha-FeOOH. Successively the obtained discoid alpha-FeOOH is reduced with a reducing gas and thereby the discoid metallic iron magnetic powder which is discoid in the shape of the grain and has 0.03-1mum grain size and 3-10 ratio of grain size to thickness is obtained. When this magnetic powder is used as the magnetic powder for the magnetic recording, a magnetic recording medium having high coercive force and saturation magnetization is obtained.

Abstract: PURPOSE:To leave an oxide superconducting layer of a spiral shape and to use it as a coil for a superconducting magnet by a method wherein the oxide superconducting layer is formed in a shape close to a final shape and the part other than the spiral shape is removed or made to lose its superconductive property. CONSTITUTION:A magnesium oxide layer 2 as an intermediate layer is formed on a cylindrical base material 1; an oxide superconducting layer 3 is formed on this magnesium oxide layer 2. A region 3b other than a spiral-shaped part refers to a hatched region that is sandwiched between two-dotted chain lines; the oxide superconducting layer in this part is removed; alternatively, superconductivity at an operating temperature of the oxide superconducting layer in this part is lost.

The grounded wheel 1 reaches a partially tooth-cut portion of the large gear 6 and is turned into an idle state. Under the condition, when the advancement is made and a rear wheel goes up on the stepped part, the front weel 9 resumes the original position by the aid of a spring 12. Then, the whole wheelchair is slightly returned rearward from the condition, the small gear meshes with the large gear 6, it goes up, and the front wheel 9 goes down and is grounded. The wheel 1 is returned to the original position and turned into its initial condition by the aid of a spring 13.  With such a constitution, it is posible to climb up to the height almost half the radius of the front wheel without a large power of a user.

Abstract: PURPOSE:To accurately measure the flow rate of a granular article to be treated, by a method wherein a detected value calculated in such a state that there is no granular article to be treated in a passage is set to a reference value and the flow amount/hr of the article to be treated is calculated on the basis of the function of the ratio of the flow rate of the granular article to the detected value. CONSTITUTION:In a threshing apparatus, the transmitter 24a and receiver 24b of an ultrasonic sensor are provided to a passage (second return cylinder) 22 in opposed relationship to detect the flow amount/hr of the article to be treated in the passage 22. The control of the ultrasonic sensor is performed by a controller 28 and a signal having constant intensity is transmitted from the transmitter 24a for a minute time at every appropriate time interval by an oscillator 32. The receiver 24b receives the reduction of the permeability of an ultrasonic wave corresponding to the increase in the flow rate of the article to be treated to convert the same to an electric signal. The detected value of ultrasonic noise in such a state that no article to be treated flows is set to a reference value and the ratio of the detection value when the article to be treated flows and the reference value is multiplied by proportion constant to calculate a so-called compensated detected value.

Abstract: PURPOSE: To reduce the BOD concentration of the supernatant of aerobic treatment by subjecting the biodecomposable sludge to aerobic treatment at high temperatures then cooling, and adding untreated excess sludge and subjecting the same to aeration treatment again.  
     CONSTITUTION: In treating of organic waste water, biodecomposable sludge such as excess sludge is subjected to aerobic digestion at liquid temperatures of 40W100°C with good efficiency. Thereupon, when the treatment is accomplished at high liquid temperature, the BOD concentration of the eluate of the digested sludge after the treatment becomes high. Thereupon, the high temperature aerobic digested sludge is cooled, to which fresh activated sludge is added and again aeration treatment is performed. Then, the BOD concentration of the supernatant is reducd because the sludge has adsorptivity.
