Abstract: A crank press includes an encoder measuring an angle value of a servo motor, a strain detector module generating a converted load value associated with deformation of a machine body, a memory storing at least one relation between an angle value and each of an upper torsion limit and an upper load limit, and a controller calculating a torque command value based on a position command, reading the upper torsion limit corresponding to the measured angle value, determining whether the torque command value exceeds the upper torsion limit, outputting the torque command value when negative, and outputting the upper torsion limit when affirmative. The controller further stops the servo motor when the converted load value exceeds the upper load limit corresponding to the measured angle value.

Abstract: Provided herein is a structure for use in an electrochemical cell system. The structure includes a dry component housing (180) including a plurality of dry components (110), including an anode (112) and a cathode (132). One end of the dry component housing comprises an electrolyte concentrate (solid or liquid) reservoir (150). The electrolyte concentrate reservoir and the dry components are in fluid communication via a flow control device (170), aperture (172) or system (170a). An electrochemical cell is formed using the structure, in addition to a source (262). When the water is added in the proximity of the electrolyte concentrate reservoir, diluted electrolyte is introduced through an electrolyte flow control device, structure or system, the cell is activated.
