line for controlling the pressure of fluid entering
said port, and hence directly controlling the
acceleration of said movable die section at all
times during movement of said movable die section
between said first and second positions.
In applying this language to the apparatus disclosed by Sato,
it is evident that Sato discloses a sensor 31 which senses the
position of movable die section 16 and produces an output
signal fed to a comparator 33. However, claim 21 further
requires that the sensor sense "at least a portion of ... a
position profile of said movable die section at all times
during movement of said movable die section between first and
second positions" (emphasis added), the first and second
positions being defined as, in essence, the closed (molding)
position and the open (ejection) position of the movable die
section, respectively. We find no disclosure in Sato of how
the movable die is controlled during its movement from the
closed position to the ejection position. Sato’s description
of the operation in col. 4, lines 4 to 32, states in lines 5
to 7 simply that "the metal molds are opened by moving the
movable metal mold 16 to the left [in the drawing] to take out
the molded product," and the remainder of the description is
concerned with operation of the machine when the movable mold
