An electromagnetic contactor includes an iron core members formed of a first core bent in a U-shape, and a second L-shaped core contacting the first core. A coil is wound around a spool disposed on an upper arm of the first core and the second core to form a main leg while a lower arm of the first core constitutes a yoke. Thus, the iron core members can be processed by a press machine operating at a normal cutting speed, and welding and polishing operations can be eliminated to thereby reduce the number of processing steps required.

A terminal device for an electric equipment is formed of a frame having a terminal housing, a fixed terminal situated in the terminal housing, and a terminal screw having a male screw to be coupled to a tapped hole of the fixed terminal and an inverse L-shaped washer. The inverse L-shaped washer includes one side for rotatably holding the male screw and a guide plate section bent relative to the one side. A guide groove is formed in the terminal housing for receiving the guide plate section therein to vertically guide the same. Also, the terminal device includes an engagement section having a first engaging part formed on the guide plate section and a second engaging part formed at a portion facing the guide groove and engaging the first engaging part to temporarily hold the guide plate section in the guide groove. Thus, the terminal screw can be held directly above the tapped hole, which enables the male screw to be stably and easily inserted into the tapped hole, and which facilitates simple rewiring.

Material to be treated such as garbage is charged into a first rotary kiln 14 to be mainly dehydrated and charged into a second rotary kiln 18 to be carbonized. The first rotary kiln 14 has a first nozzle pipe 11 therein for spouting a first high temperature gas and the second rotary kiln 18 has a second nozzle pipe 15 for spouting a second high temperature gas, mainly high temperature superheated steam with a temperature higher than a temperature of the first high temperature gas. The carbonized material is discharged outside after a temperature thereof is lowered to prevent spontaneous combustion in an atmosphere. Thereby, it is able to provide an apparatus for thermal treatment using superheated steam which can be built relatively small and by which treatment time can be shortened, and further, the final carbonized material can be used as charcoal.

The electro-magnet relay of the present invention utilizes an iron core and an armature both formed as flat plates stacked together. Further, a stationary leaf spring and a moveable leaf spring are provided in the middle section of the iron core having two legs and being shaped as an inverted U. The armature is supported in a hole located in the insulating substrate and may swing to a degree determined by a striking piece formed on the armature. Coil terminals and contact terminals protruding from the bottom of the insulating substrate are arranged in a single line in the electro-magnetic relay of the present invention and may be installed on a high density printed circuit board.

Although a chelating agent solution having radioactive contaminants is solidified by mixing with cement and then stored, a vast storage place is required for storing an enormous amount of chelating agent solution. When such a chelating agent solution is treated with an ion-exchange resin, a large amount of ion-exchange resin is required, and a large amount of ion-exchange resin having radioactive contaminants is produced. The present invention thus provides a method of treating a chelating agent solution having radioactive contaminants, which can significantly decrease the amount of the chelating agent solution having radioactive contaminants, and which, when an ion-exchange resin is used, can significantly decrease the load on the ion-exchange resin without producing a large amount of ion-exchange resin having radioactive contaminants. In this method, a chelating agent solution having radioactive contaminants is electrolyzed by a direct current to produce various gases and eliminate the chelating property, a holding agent such as a coagulant-precipitant or a metal scavenger, which holds metal ions to form a water-insoluble substance, is then added to the chelating agent solution to form an insoluble substance which is then filtered off, and the filtrate is treated with an ion-exchange resin. The produced purified water may be collected, or a chelating agent may be added to the purified water to form a chelating agent solution used for decontaminating a radioactive contaminated substance.

The invention provides a method and apparatus for recovering a target material including using an adsorbent such as activated charcoal, the target material recovered in a continuous manner, as well as a method and an apparatus for recovering a solvent based on such a method and apparatus. The adsorbent for the target material is rotated to move the adsorbed material in direction of centrifugal force while the target material is attracted to the adsorbent. The excess target material is detached from a peripheral edge of the adsorbent by centrifugal force. The detached material is recovered by a recovery device provided in corresponding relation to the adsorbent.

A heat treatment apparatus has a first screw conveyor, a second screw conveyor, a first nozzle pipe, and a second nozzle pipe. If the first screw conveyor rotates right, the first nozzle pipe is disposed on the left lateral side of the first screw conveyor. If the first screw conveyor rotates left, the first nozzle pipe is disposed on the right lateral side of the first screw conveyor. If the second screw conveyor rotates right, the second nozzle pipe is disposed on the left lateral side of the second screw conveyor. If the second screw conveyor rotates left, the second nozzle pipe is disposed on the right lateral side of the second screw conveyor.
摘要:
A terminal device for connecting contacts to terminal strips fixed on respective terminal housing portions of an electrical apparatus, each of the terminal strips having a screw hole, the terminal housing portions being separated by insulating walls from one another. The terminal device includes a plurality of terminal screws, each including a male screw, and an L-shaped washer supported loosely and rotatably on the male screw and having a guide plate portion extending opposite to the terminal strip; a terminal cover covering the terminal housing portions and having round holes for handling the respective terminal screws; a guiding portion each including a vertical trench formed on a side plate of the terminal cover and having an opening facing the round hole, for guiding the guide plate portion slidably to and from the terminal strip along the vertical trench; a plurality of coupling claws, each disposed between the round hole and the male screw, for holding the terminal screw such that a tip of the male screw is spaced from the terminal strip for a certain distance; and a swinging mechanism for releasing the guide plate portions from the guiding portions, respectively, when the tips of the male screws are coupled to the respective terminal strips, to allow the washers to swing.
