A movable device provided with bottom electrodes and a basic conductive layer fixed to a substrate, an elastic shaft of a carbon nanotube with a bottom end fixed on the basic conductive layer and standing up, and a top structure including a top electrode spaced away from the bottom electrode and fixed to a top end of...

A movable robot includes a main body unit and at least three wheel units. The wheel units are connected with the main body unit. The wheel units at least partially project from the main body unit. The wheel units have contact portions for contact with a floor surface. Rotation drive devices operate for rotating the wheel units independently of each other. The main body unit is moved along the floor surface as the wheel units are rotated by the rotation drive devices. Lines projected onto the flo...

An assembly includes a track having a length; a goalie structure; and a base that supports the goalie structure on top of the track. The base has wheels and a motor cooperating with at least one of the wheels for moving the goalie structure along the length of the track. A player, for example, a hockey player or a soccer player, can practice scoring goals against the goalie structure. The goalie structure is preferably inflatable, and the track is preferably constructed from a plurality of track...

A movable blind fastened to the interior of an automobile comprises a cradle in the bottom and a bracket in each end of the cradle, with each bracket having a recess. Two engagement members each have a projection fitted into the recess and a double trough. Two plate members each have two pairs of opposite protuberances, a stop between the pairs of protuberances, and a shaft, with the protuberances and the stop being fastened to the double trough. Two pivot members each have slots disposed around...
