A bipedal robot of the present invention has a trunk consisting of an upper trunk and a lower trunk which are rotatable around a rotation axis relative to one another. The upper trunk has shoulders on the right and left sides. An arm is provided at each shoulder. A pair of right and left legs is attached to lower ends of the lower trunk. A storage battery is mounted to the back of the upper trunk, positioned within a shoulder width. The storage battery is positioned below the top of a head mounted on the upper trunk. When the robot walks a narrow passage or corridor having a width slightly larger than the width thereof, for example, this arrangement prevents the storage battery from interfering with the passage or the like.

In a hybrid power supply device constituted such that a secondary battery ( ) is charged by a fuel battery ( ) and electric power is supplied from the secondary battery ( ) to a load ( ), even when there are variations among residual capacities of individual unit secondary batteries ( ) constituting the secondary battery ( ), the secondary battery ( ) can be charged properly without causing overcharging in each of unit secondary batteries ( ). The fuel battery ( ) is divided into a plurality of unit fuel batteries ( ), each consisting of a predetermined number of cells, and each unit hybrid power supply ( ) is constituted by connecting each unit fuel battery ( ) with each unit secondary battery ( ) through each charging switch ( ) in parallel. The charging switch ( ) is controlled independently for each unit hybrid power supply ( ) on the basis of the residual capacity of each unit secondary battery ( ) to perform charging of the unit secondary battery ( ) by the unit fuel battery ( ).

Hybrid power supply device

An amorphous solid solution of V.sub.2 O.sub.5, CoO.sub.2, P.sub.2 O.sub.5, MO (wherein M represents an alkaline earth metal element) and at least one lithium compound selected from the group consisting of lithium-oxygen compounds, lithium halides and lithium oxygen acid salts is formed by melting precursor materials therefore, then the melt is put into water or pressed with metal plates to quench it, and the solid solution is heat treated above its glass transition temperature, the resulting solid solution being used as a cathode material for a lithium battery, thereby obtaining the lithium battery preventing the capacity of a carbon anode from lowering and excellent in long-term cycle stability.

Cathode materials for lithium batteries and methods for producing the

An alkali ion-absorbing/desorbing carbon material excellent in absorption and desorption of alkali ions and useful for an electrode material for a secondary battery or an anode material of a lithium battery is obtained by heat treatment at 300.degree. to 1000.degree. C. of an organic polymer having an aromatic structure, wherein the monomers of the aromatic organic polymer are linked together by o-bonding or m-bonding, or wherein the aromatic organic polymer has a branched structure or a crosslinked structure. The carbon material has a randomly stacked, condensed aromatic ring structure.

Alkaline ion-absorbing/desorbing carbon material electrode material for

An organic polymer compound such as poly(p-phenylene) is heat treated under an atmosphere of an inert gas such as argon at 500.degree. to 1,500.degree. C., preferably in the vicinity of a carbonization temperature (the range from the carbonization temperature to the carbonization temperature+300.degree. C.) to obtain a carbon material having properties of both a carbon substance and an organic substance.
