An inputting device, used for electronic devices, for example, is disclosed. The biological compositions can be used to retard the growth of stomach cancer cells andor prolonging the time of survival of the subject. A planetary gear assembly includes a sun wheel mounted on the output shaft, an annulus secured to the motor housing and having an internally toothed annular surface, and a planet wheel meshing with the toothed surface and the sun wheel. The orificing device includes a plurality of steps that may be varied in size and shape to dampen the pressure signal to the resolver so that independent control for the pilot operated control valves is achieved. The configurations of the wells may also be modified by adding vents or flow dividers to enhance fluid flushing and gas removal capability. The apparatus can perform two-sided copying by transferring and fixing an image on a first surface of recording material, and then transferring and fixing an image on an opposite surface.
