Title: Final treatment of surplus sludge and device thereof
Inventor: HIRAGA KAZUO
IPC: C02F11/14
Filed: 1994-10-25
Abstract: PURPOSE: To provide a method of finally decomposing surplus sludge generated by a primary treatment of foul water discharged from a household and other drain and a device using the method. CONSTITUTION: Surplus sludge contained in foul water discharged from a household and other drain is dehydrated to the water content of 63 to 70% using a dehydrator with a flocculant. On the other hand, a carrier of saw dust with a grain diameter of 0.1 to 25mm and a useful microbial group are previously charged and mixed in a stirring container equipped with a means for adjusting the water content, a means for adjusting pH value and a means for adjusting temperature. Thus the internal atmosphere of the container is maintained at the water content of 60 to 65%, pH value of 6 to 8 and the temperature of 35 to 45 deg.C as the optimal conditions for proliferation activity of useful microbes.  Further, the dehydrated sludge is charged into the stirring container, and is stirred and mixed at slow speed continuously or intermittently with a concurrent action to ventilate the saw dust carrier uniformly. In addition, the sludge and the saw dust carrier, the volume of which is reduced following the promotion of a decomposition/digestion action by the microbes, are additionally charged and this additional charge is repeated. Thus this device is continuously operated semipermanently to perform the biological decomposition and digestion of almost all the charged sludge.

Title: Universal frame body
Inventor: KATO SUSUMU
IPC: H05K7/18
Filed: 1990-10-26
Abstract: PURPOSE:To require no weight-mounting space for adjusting the balance of weight, to generate no such inclination as that in the case of a rubber vibration isolator and to surely prevent resonance phenomena at a low frequency by inserting powder or granular material into the hollow part of a hollow cylindrical frame member. CONSTITUTION:A predetermined quantity of metal powder 3 is inserted into the hollow parts of respective frame members 1 and connecting members 2 are pressed into both ends of the member 1 for the purpose of assembling the title frame body. Because the both ends of the member 11 are closed by the member 2, the metal powder 3 does not leak from the hollow part. The member 1 is divided to a suitable length by the member 2 so that it is possible to prevent the metal powder from deviating beyond the limit in the hollow part. As the metal powder is inserted into the hollow part of the frame member to keep the balance of weight, a weight mounting space is unnecessary. Also, as resonance is prevented by the damper effect of the powder, there occurs neither resonance phenomena in a low-frequency region nor such inclination due to deformation as that in the case of a rubber vibration isolator.
