摘要:
In an automatic planting apparatus (10) a first predetermined number of pieces of blocks (4) in the first row of a plant supporting sheet (3) on a sub-conveyer (13) are torn off by a block separator (25). The blocks (4) that are torn off are inserted into holes (2) in the first row of a panel (1) on a main conveyer (11) by a block inserting unit (39). The panel (1) is then fed forward by a row pitch by a main feeder (15) and slid laterally with the sub-conveyer (13) by a distance corresponding to the width of each block (4) by a sliding unit (17). The block inserting operation is then repeated.

摘要:
A wastewater treatment method in an embodiment includes: mixing primary aggregates made of magnetic substances and a dispersion medium to make a suspension; and passing the suspension through a filter to allow the primary aggregates to remain on the filter and to form a secondary aggregate made of an aggregate of the primary aggregates. Further, the wastewater treatment method in the embodiment includes; passing wastewater through the secondary aggregate to remove suspended solids and oil in the wastewater; dispersing the secondary aggregate in a dispersion medium to decompose the secondary aggregate into the primary aggregates and to wash the primary aggregates; and collecting the primary aggregates with magnetic separation.
摘要:
A polymer composite is provided for a water treatment. The polymer composite with excellent workability is capable of adsorbing impurities in water, being rapidly separated from the water using magnetic forces. The polymer composite includes secondary aggregates. The secondary aggregates are formed of clumped particles, the particles being magnetic particles covered with a polymer. The polymer composite has porous structures suitable for adsorbing underwater impurities.

摘要:
A workpiece in a container is held by a robot based on a result of detection of shape information in the container by a shape sensor, a holding condition of the workpiece held by the robot is inspected by an inspection device, and the workpiece is transferred to a subsequent step by the robot when the inspection device has determined that the holding condition of the workpiece is acceptable. When the inspection device has determined that the holding condition of the workpiece is unacceptable, the held workpiece is placed on a temporary placement table, the shape of the workpiece is again detected by detecting the workpiece using the shape sensor, and the workpiece is held and transferred to the subsequent step by the robot based on a result of the detection.
