IPC: C02F1/52
Filed: 1986-07-14
Abstract: PURPOSE:To execute a solid-liquid sepn. operation in a short period by adding a flocculating agent to fluid in which solid particles and liquid co-exist, subjecting the fluid to the solid-liquid sepn., releasing the overflow of the separated liquid and subjecting the sludge-like fluid to the solid-liquid sepn. by a solid separating and dehydrating device. CONSTITUTION:The treating fluid added with the inorg. flocculating agent and high-polymer flocculating agent is charged into a funnel-shaped mixing tank 2 where the flocs in the treating fluid are settled and separated. The precipitate of the mixing tank 2 is stored in a slurry tank 3 and is fed to the solid separating and dehydrating device 15 which is driven by a gas-liquid mixing type vacuum pump. The pressure in the device 15 is reduced by the gas- liquid mixing type vacuum pump to dehydrate the treating liquid mixed with the precipitate from the tank 3 and contained therein to separate the same to a solid component and liquid component. The supernatant liquid of the tank 2 and the liquid component discharged from the device 15 are stored in an effluent tank 4. The liquid component discharged from the tank 4 is fed back into the underground or is made into releasable clean water by a pH treatment.

Title: Arc melting method
Inventor: TANAKA SHIYUNICHI
IPC: C22B9/20
Filed: 1983-09-13
Abstract: PURPOSE:To perform safely refining with an excellent refining effect by forming a magnetic field in the direction intersecting orthogonally to an arc in the stage of arc melting and refining using consumable electrodes disposed in a horizontal direction in a vacuum. CONSTITUTION:A pair of consumable electrodes 1, 1 are disposed to face each other horizontally in a vacuum or inert gaseous atmosphere and an arc A is generated to melt and refine the consumable electrodes by which the electrodes are refined to a metal having high quality. A magnetic field B is applied in the direction intersecting orthogonally with the arc A to act the upward or downward force F on the arc A and the molten metal by Fleming's left-hand rule. The metal melted by the arc is supported in the arc A by said force F without dropping immediately and is further heated until the metal drops in the form of the droplet to the extent that the droplet cannot withstand gravity. The droplet solidifies in a casting mold 2 and forms an ingot. Since the temp. of the droplet is high, the ingot does not become like a millet-and-rice cake and since the arc A is not generated between the walls of the casting mold, there is no danger owing to the failure of the casting mold.

Filed: 1989-06-29
Abstract: PURPOSE:To absorb the noise in the signal fed to the IC by forming a penetration capacitor with a metal pin, a derivative, and a conductive member. CONSTITUTION:When a sharp pulse type noise is mixed in the signal on a base 3, the noise in the signal is released into a metal tube 6 by a penetration capacitor which is formed of a metal pin 1, a derivative 5, and the metal tube 6, to form a socket, in the process to feed the signal to the lead of the IC through a socket device, and it is not reached directly to the lead of the IC. The noise released in the metal tube 6 is bypassed to an earth signal wire on the base 3 from an earthing wiring 7 through a dielectric type metal member 4 to form the socket device. As a result, only the pulse type noise mixed in the signal can be bypassed efficiently, and released to the earthing member on the base.
