摘要:
Dusts containing zinc and/or lead in the form of oxides and one or more reducing agents are mixed with each other before or after being introduced into a heat treatment furnace. The mixture is heated to a given temperature range under a substantial vacuum so that the zinc and/or lead in the form of oxides are reduced to zinc and/or lead in the state of pure metals and evaporated in the furnace. The evaporated zinc and/or lead are introduced into a retrieving container also under a substantial vacuum and at a given temperature where the evaporated zinc and/or lead pure metals are condensed and retrieved.
摘要:
A method of treating dust exhausted from a melting furnace in melting an iron-contained material, comprising the steps of: melting the iron-contained material, with air inside the melting furnace shut out from outside air and collecting the dust from the melting furnace into which a gas exhausted from the melting furnace and containing the dust is introduced; performing a lead-collecting process of collecting water, chloride, fluorine, and lead by heating the exhausted dust in vacuum; and performing a zinc-collecting process of collecting metallic zinc contained in the dust by heating a residue of the exhausted dust in vacuum.
摘要:
A treating method of recovering zinc in the metal state from a waste containing the zinc in the oxide state, lead, chlorine, fluorine, and water comprising a mixing process 90 of obtaining a to-be-treated mixed material 70 by mixing a steel dust 7 and a reducing material 8 together; a chlorine recovery process 91 of recovering the chlorine and the water by heating the to-be-treated mixed material 70; a lead recovery process 92 of recovering fluorine and lead by heating the to-be-treated mixed material 70 under vacuum; a zinc recovery process 93 of recovering metallic zinc by heating the to-be-treated mixed material 70 at a temperature higher than that in the lead recovery process 92 with the vacuum state maintained so as to reduce and vaporize zinc; and a residue recovery process 94 of recovering a residue 79 of the to-be-treated mixed material 70. This construction allows the metallic zinc to be recovered at a high purity from a zinc oxide-containing waste and an on-site treatment to be accomplished.
摘要:
Metal plated steel sheet scraps are heated to a temperature in the range of about 200.degree. C.-500.degree. C. so that organic material adhered to the scraps is evaporated and removed. Then, the scraps from which organic material has been removed are heated to a temperature in the range of about 500.degree. C.-950.degree. C. so that the plated metal, for example zinc or aluminum, is evaporated. The evaporated metal flows to a retrieving device where the evaporated metal is condensed and retrieved.

It is possible to control a welding in a high speed and a high precision large electric current, and consumption electric power is also reduced. In the welding transformer, a loop magnetic core 25, a wound primary coil 12, plural positive side coils 14 and plural negative side coils 16 that are alternately sandwiched between respective gaps 12a of the primary coil 12, are comprised. A coil is fixed on the other surface of a contact base member 62. On the other surface of the contact base member 62, a first connection polar board 44 is electrically connected to a positive side electric conductor 30 through the first connection polar board 44. A negative side coil 16 is electrically connected to a negative side electric conductor 32. The connecting part of the positive side coil 14 and the negative side coil 16 is electrically connected to the third connection polar board 48. By sandwiching a thin insulation layer 31, a positive side electric conductor 30, a rectifying device 18 and a first polar board 34 are arranged on one side; A negative side electric conductor 32, a rectifying device 20 and a second polar board 36 are arranged on the other side; and the first polar board 34 and the second polar board 36 are electrically connected to a third polar board 38. It is possible to use by combining plural units and by connecting an output side in parallel in a small size and a large capacity.
摘要:
An information processing apparatus that acquires first posture information corresponding to the information processing apparatus and a first distance coordinate corresponding to the information processing apparatus, and second posture information corresponding to another information processing apparatus and a second distance coordinate corresponding to the another information processing apparatus. The information processing apparatus then calculates an object's position in a virtual space based on the first and second posture information and the first and second distance coordinates.
摘要:
When extrusion of a molten resin by means of an extruder is started, a simple polyetherimide resin is melt extruded from a lip portion 7a of a T-die 7, and a film of the simple polyetherimide resin is molded. The molding material is then switched to a resin composition including the polyetherimide resin and a fluorine resin and then a film of the resin composition is continuously extruded and molded from the T-die 7. Having been covered with a very thin film 8a of the simple polyetherimide resin, on a flow passage face of the lip portion 7a of the T-die 7, a resin composition layer 8b including a polyetherimide resin and a fluorine resin, which has affinity with the film 8a, is then formed at a center part.

An airbag system is configured to fulfill its role on a saddle-ride type vehicle even when the vehicle collides with a side of a vehicle moving in a generally perpendicular direction. An embodiment of the airbag system includes an airbag which is configured to the inflated and fully upward from the vehicle front of a rider. The airbag includes a head part opposite to a rider's head during inflation and deployment, and a neck part which rises upward from the vehicle and toward the head part. The neck part has a width in a direction of vehicle width which is narrower than that of the head part. The neck part includes neckings curved inward in the direction of the vehicle width.
