Abstract: A connection bar mounting structure includes: link members, each including a first hole part in a middle part; vehicle members, each configured to rotatably support each link member at a first fixation part of each link member; side frames, each configured to rotatably support each link member at a second fixation part of each link member opposite to the first fixation part across the first hole part; and a connection bar, each end thereof fixed to the first hole part of each link member. Each link member has a first bending rigidity reduced section between the middle part and the first fixation part and a second bending rigidity reduced section between the middle part and the second fixation part, the first and second bending rigidity reduced sections having bending rigidity smaller than those of the middle part, the first fixation part, and the second fixation part.

Abstract: The present invention relates to a hydrogen supply device which supplies hydrogen by selectively permitting permeation of hydrogen contained in a hydrogen containing gas (G1). This device includes: a first metal layer (2) which dissociates hydrogen molecules into hydrogen ions by a catalytic reaction and has hydrogen permeability; a second metal layer (3) which creates hydrogen molecules by bonding hydrogen ions to each other using electrons and has hydrogen permeability; a hydrogen permeation layer (1) which is interposed between the first metal layer (2) and the second metal layer (3) and permits permeation of the hydrogen ions from the first metal layer (2) to the second metal layer (3) by the application of a voltage; and a voltage application (7) for applying the voltage to the hydrogen permeation layer (1) by setting the first metal layer (2) as an anode and setting the second metal layer (3) as a cathode.

Abstract: A transformable toy assembly is disclosed which provides at least two assembly elements separable and combinable with respect to each other and independently reversibly transformable between at least two forms different from each other. The assembly elements are combined together in various forms to provide forms different from each other.

Abstract: A reconfigurable toy assembly having foldable portions to allow the toy assembly to simulate a toy combination vehicle having a tractor unit and a trailer unit separatably connected to each other. The tractor unit when separated from the trailer unit is reversibly reconfigurable into a robotic humanoid form, while the trailer unit is reversibly reconfigurable into a play space for the robotic humanoid.
