摘要： PURPOSE: To enhance the transfer speed, to prevent a print circuit board from dropping and to aim at reducing the dripping area of treating liquid, by laying a print circuit board gripping device in an elevatable frame in parallel with the running direction.
CONSTITUTION: A gripping device for print circuit boards 3 is laid in an elevatable frame 2 in parallel with the running direction. In this arrangement shocks upon the print circuit boards 3 due to stopping of the motion on running is reduced, and therefore, it is possible to increase the speed of transfer and therefore to enhance capacity of transfer per time. Further, it is possible to aim at preventing the print circuit boards from dropping and at preventing treating liquid from scattering, thereby it is possible aim at reducing the dipping area of the treating liquid.

摘要： PROBLEM TO BE SOLVED: To provide a process for operating a rotary stirrer in compost fermentation equipment wherein the compost is prevented from being splashed out of a fermentation tank when a stirring rotor begins stirring, by decreasing area required for discharging the compost. SOLUTION: A prime mover 25 equipped with an inverter controller, which controls the rotating speed of the stirring rotor 24, is mounted on the rotary stirrer 12. By rotating the stirring rotor 24, organic matters 5 stacked in the fermentation tank 14 are stirred with agitating blades 22. The rotating speed of the stirring rotor 24 is controlled by the inverter controller so that it starts rotating at a low speed and gradually accelerates. This prevents the organic matters 5 from being scattered around the compost-discharging area at the beginning of stirring. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To improve water quality of treated water by an apparatus wherein an aeration means for forming an aeration phase on the upper part of a deep tank type bioreactor and a circulation means for forming a static water phase between a carrier expansion phase formed in the lower part of the bioreactor and wherein a carrier carrying microorganism floats up slightly and an aeration phase are installed. SOLUTION: After waste water flowing into a bioreactor 16 is sufficiently aerated in an aeration phase 42 by means of an aeration device 18, it is lowered as a downward stream in a communication pipe 26 and is delivered to the bottom part of the bioreactor 16. The waste water delivered to the bottom part of this bioreactor 16 is elevated as a up-blow in the bioreactor 16 and by keeping linear velocity when it passes through a carrier expansion phase 46 formed on the lower part of the bioreactor 16 at 0.5-7cm/sec, a static water phase 48 with a flow velocity at which the carrier 14 can enough naturally settle is formed in the water region on the top side of the carrier expansion phase 46. In addition, aerobic atmospheres are formed in the upper part and the lower part of the bioreactor 16 and BOD ingredient and ammoniacal nitrogen are mainly nitrification-treated respectively in the aeration phase 42 and the carrier expansion phase 46.

摘要： PROBLEM TO BE SOLVED: To obtain the subject carrier high in nitrogen removal and wear resistance, by mixing activated sludge with fine powder of a metal oxide, allowing the mixture to stand for a fixed time to give a mixed solution, suspending the solution in a gel raw material solution and gelatinizing the suspension to include a microorganism in a hydrous gel of a polymer. SOLUTION: Concentrated activated sludge is mixed with fine powder of a metal oxide (e.g. fly ash) comprising iron oxide or silicon oxide having 5-40μm average particle diameter to prepare a mixed solution. The mixed solution is allowed to stand for 1-2 hours, is added to a raw material solution of gel comprising a polyethylene glycol prepolymer and N,N,N',N'- tetramethylethylenediamine as a polymerizing agent and suspended to give a suspension. Then the suspension is mixed with a potassium persulfate as a polymerization initiator, immediately cast into a vinyl chloride tube having 3mm inner diameter, allowed to stand for 10 minutes at 20 deg.C and gelatinized. The prepared rodlike cylindrical material is cut in 3mm length into a pellet state to give the objective included immobilized carrier in which a microorganism is included and immobilized to a hydrous gel of a polymer.

摘要： PROBLEM TO BE SOLVED: To provide a dryer which can be operated with a small equipment power, whose drying efficiency is good and whose small size can be realized. SOLUTION: A shell 12 and a bottom plate 14 are covered with a jacket 20 to form a steam chamber 22. An axial steam chamber 52 is provided in a rotating shaft 46. A fixed vane 94 having a comb teeth member 100 is fixed to the shell 12. A shearing rotary vane 70 having a comb teeth member 88 is attached to the rotating shaft 46. Sludge as a material to be dried is supplied from a supply nozzle 40 and the rotating shaft 46 is rotated while steam is supplied to the steam chamber 22 and the axial steam chamber 52. The shearing rotary vane 70 shears the sludge whose viscosity is increased, go that a surface area is increased and a drying efficiency is improved. Since the shearing rotary vane 70 also serves as an agitating vane. the sludge can be entirely uniformly dried. Since the shearing rotary vane 70 does not need to be rotated at high speed, an equipment power may be decreased. As a result, the dryer can be made compact.

摘要： PROBLEM TO BE SOLVED: To equalize filtration velocity of a solid-liquid separator as much as possible over the whole filter medium bed area. SOLUTION: Feed water to be treated is caused to flow into a cylindrical vessel 40 from an inflow pipe 42 arranged in the tangential direction thereof near the lower end thereof to generate a turning flow in the cylindrical vessel 40, and the turning flow is caused to flow out from plural discharge pipes 44 installed in the tangential direction of the peripheral surface of the cylindrical vessel 40 at the same height position thereof to constitute a distributor 3. Therefore, liquid flowing into the cylindrical vessel 40 is equally distributed and caused to flow out. The distributors 32 are applied to a solid-liquid separator, allowing the flow velocity distribution of feed water to be treated in the whole floating filter medium bed area to be equalized compared to the conventional distributors.
