  • Patent number: 6698365
    Abstract: 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.

  • Patent number: 5945900
    Abstract: 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.

  • Patent number: 5934948
    Abstract: 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.

  • Patent number: 5832393
    Abstract: 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.

  • Patent number: 5738710
    Abstract: 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.

  • Patent number: 4914411
    Abstract: 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.
