Title: Concentration device of biosludge
Inventor: MIHASHI KAORU
IPC: C02F11/12
Filed: 1987-11-30
Abstract: PURPOSE:To concentrate sludge with small labor by storing a filter bag with coarse meshes in a filter bag container with a filtered water-outlet below, and controlling the transmission flow velocity of filtered water from the filter bag by a pressure action to the internal circumferential surface of the container when a mixture liquid of sludge is stored. CONSTITUTION:A filter bag with coarse meshes which comes into contact under pressure with a slight gap (g) left with the internal circumferential surface and the internal bottom surface of the container 1 by a water pressure of a mixture liquid of sludge 6 stored is accommodated in a detachable manner within the filter bag container 1 with a filtered water discharge outlet 2 below. Then the flow velocity of filtered water from the filter bag 5 into the slight gap (g) is controlled by the afore-mentioned pressure action to the internal circumferential surface and the internal bottom surface of the container 1 when the mixture liquid of sludge is stored. As a result, a higher cost for equipment required conventionally for a large-size device is not required, and also the filter bag need not be cleaned due to clogging. Sludge can be concentrated with less labor and maintenance cost by extracting and treating sludge from a processing tank intermittently and at an unfixed timing.

Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To eliminate an unnecessary reactor component and reduce the size by a method wherein the winding direction from the winding start of the coil part to the middle point of an ACL and the winding direction from the middle point to the winding end of the coil part are opposite to each other. SOLUTION: In a balancing circuit, the winding direction from the winding start P1 to the middle point P2 of the coil part of an ACL 2 and the winding direction from the middle point P2 to the winding end P3 of the coil part are opposite to each other. A counter electromotive force generated by the part between the winding start P1 and the middle point P2 and a counter electromotive force generated by the part between the middle point P2 and the winding end P3 have polarities opposite to each other and absolute values equal to each other, so that the reactance components which are an apparent resistance components produced by those counter electromotive forces cancel each other.  As a result, the resistance component consists of an inductance only and the unnecessary reactance component is eliminated and the characteristics which are very close to the characteristics of a pure resistance can be obtained and, further, a resistor to which a large current can be applied can be obtained.

Title: Dash-pot type electromagnet
Inventor: NAKANO KUNIMITSU
IPC: H01F7/14
Filed: 1986-12-19
Abstract: PURPOSE:To simplify an assembly and quality control while reducing the number of parts by making a magnet to hold magnetic fluid being housed in a cylinder in a dash-pot type electromagnet. CONSTITUTION:When an overcurrent flows through a coil 7, magnetic fluid 8 is attracted due to the excitation of the coil 7 and the magnetic fluid 8 flows to one pole head of a cylinder 2. By the approaching of the magnetic fluid 8 the pole head 1, the magnetic flux between an armature 6 and the pole head 1 is increased so that the armature 6 is attracted by the pole head 1 resisting a return spring 11. The then delayed action is based on the viscosity resistance of the magnetic fluid 8. When a compression current flows in the coil 7, the magnetic flux generated in the coil 7 is large, so that the armature 6 works momentarily before the magnetic fluid 8 works. Accordingly, the conventional silicone oil, plunger and return spring are unnecessitated, thereby resulting in the simplification in assembly and the reduction in the number of component parts. Further, the decision of magnetic force of a magnet 9 can perform change and regulate a working threshold current.
