摘要:
In a robot with two or more leg links having ankle joint respectively and pivotably linked to a torso, the robot walks naturally by making the ankle joint of a grounded leg link rotate freely by using passive movement. A controller executes controlling operation of calculating target joint angles of remaining joints other than the ankle joint of the grounded leg link based upon the measured joint angles of the ankle joint of the grounded leg link in the lateral and forward direction. The target joint angles of the remaining joints are calculated so as to satisfy the following condition that a tilting angle of the torso matches a target tilting angle determined based upon the measured joint angle of the ankle joint of the grounded leg link in the forward direction, a cycle period of the idle leg link from lifting to grounding, and a target stride of the idle leg link.

Methods and apparatus are taught for selectively oxidizing carbon monoxide in a source of gas containing carbon monoxide and hydrogen. A gas containing carbon monoxide and hydrogen is fed into a membrane reactor (10, 50, 60) capable of selectively absorbing the carbon monoxide. Preferably, the reactor comprises a substantially defect-free zeolite membrane (4) having at one metal that acts as an oxidation catalyst. The zeolite membrane (4) may be supported on a porous ceramic support (2, 52, 61) and the average pore diameter is preferably between about 0.3 nm and about 1.0 nm. Moreover, the substantially defect-free zeolite membrane (4) preferably has a thickness between about 0.1 micron and about 50.0 microns. The at least one metal is preferably capable of selectively oxidizing the carbon monoxide and is preferably platinum. Preferably, the temperature of reactor housing is maintained at about 200-300° C.

摘要:
To provide a composite that can find application to various uses in a wide spectrum of fields, for example, sealing members, such as a joint sheet, a gasket and a packing, for use in junction portions, etc. of pipings of power plant and chemical plant, radiation sheets, electromagnetic wave shielding members, soundproof sheets, etc., and provide a process for producing the composite; a gasket or packing based on the composite and a clay dispersion liquid used for the composite. There is provided a composite composed mainly of graphite and clay and having the structure of graphite laminated with and/or impregnated with clay. The composite is produced by subjecting an exfoliated graphite sheet or film or a molding therefrom to coating with and/or immersion in a clay dispersion liquid with clay particles dispersed therein, or by laminating together of an exfoliated graphite sheet and/or film and a sheet and/or film composed mainly of clay. Further, a gasket or packing is produced by molding the composite.
