Abstract: A shaping apparatus that fabricates a three-dimensional object by stacking a material layer formed of a shaping material, comprising: a conveyance belt that supports and conveys the material layer; a heating roller that is one of rollers supporting the conveyance belt and heats the material layer supported by the conveyance belt via the conveyance belt; and a shaping section that stacks the material layer on a downstream side of the heating roller in a conveyance direction, wherein a size of a contact area as an area in which the heating roller and the conveyance belt are in contact with each other in the conveyance direction is larger than a maximum possible size of the material layer in the conveyance direction.

Abstract: A gas sensor that can enhance gas detection sensitivity more than the conventional sensors with a simple configuration is proposed. An electric double layer including a gate insulating layer is formed in an ionic liquid (IL), a change of a state of the gate insulating layer in the ionic liquid (IL) that occurs by absorbing a gas is directly reflected in a source-drain current (Isd) that flows in a carbon nanotube (8). Therefore, the gas detection sensitivity can be enhanced more than in the conventional sensors. Further, since the ionic liquid (IL) can be simply provided on a substrate (2) to be in contact with the carbon nanotube (8) and a gate electrode (7), the configuration that chemically modifies a surface of the carbon nanotube with a plurality of polymers as in the conventional gas sensors is not needed, and the configuration can be simplified correspondingly.
