Abstract: A moving body includes a housing, a traction motor, a plurality of elevator motors and a battery. The traction motor allows the housing to travel along a traveling surface. The plurality of elevator motors actuates an elevator unit, the elevator unit being configured to be elevated and lowered with respect to the traveling surface. The battery supplies electric power to the traction motor and the plurality of elevator motors. In the moving body, the plurality of elevator motors, the traction motor, and the battery are distributed when viewed perpendicularly to the traveling surface. The moving body further comprises at least one driving wheel to support the housing on the traveling surface. The plurality of elevator motors, the traction motor, and the battery fall, in a direction perpendicular to the traveling surface, within a range defined by a diameter of the at least one driving wheel.

Abstract: The shopping assistance system includes a basket body, a management system and a packing machine. The shopping basket includes a basket body, a goods information receiver and a transmitter. The basket body allows goods to be put in. The goods information receiver is configured to read respective goods information from each of the goods to acquire pieces of goods information on the goods. The transmitter is configured to transmit the pieces of goods information acquired through the goods information receiver. The management system includes a receiver configured to receive the pieces of goods information from the transmitter. The packing machine is configured to transfer the goods put in the basket body together from the basket body to a container.

Abstract: A support has a loading surface that is formed for placement of a merchandise. A guide is disposed around the support and along an outer circumference of the loading surface. A drive unit changes a disposition of a main mechanical unit from a first disposition to a second disposition. A level of the support relative to the guide in the second disposition is lower than the level of the support relative to the guide in the first disposition. The main mechanical unit in the first disposition supports a bottom of a bag with the loading surface, while the bag with a bag mouth facing downward is put on the support and the guide from above. The main mechanical unit puts the merchandise into the bag by allowing a side periphery of the bag contiguous to the bottom of the bag to stand upward from the bottom of the bag via the guide by changing the disposition of the main mechanical unit from the first disposition to the second disposition.

Abstract: This invention concerns treatment of the heat-fusible materials by use of a fusing agent, according to which a fusing agent capable of producing red hot "embers" by combustion is applied to the surface of a worked object such as a sign formed from a heat-fusible material and worked at a construction site or to the area to be newly worked, and then said fusing agent is ignited and burned so that the combustion heat of the resultantly produced "embers" is directly conducted to the material to be worked to thereby remove the fused material from the worked area or fuse and affix the material to the working area.
