been apparent from the designs and constructions of the cutting
machines described by Johnson, Langworthy and Ambrosio. Each of
Johnson, Langworthy and Ambrosio reasonably appear to describe a
cutting machine comprising a base including a top surface on which
a workpiece to be cut is supported, a circular saw blade, a
circular saw assembly having a motor covered by a housing, the
motor shaft of the motor disposed in parallel with and above the
saw shaft, and a transmission means through which the motor shaft
is connected to the saw shaft so that an axis of the motor shaft
10 is shifted from an axis of the saw shaft by a distance which is
greater than or equal to the radius of the circular saw blade,
wherein when the circular saw assembly is tilted in either of
opposite directions by an angle greater than or equal to 45
degrees with respect to the zero-tilt angle position, the housing
does not contact the top surface of the base. Persons having
ordinary skill in the art reasonably would have expected to be
able to inexpensively eliminate the prior art-recognized
requirement to turn the workpiece in order to cut angles +45
degrees with respect to the zero-tilt angle position using a
20 desk-top cutting machine by applying the design, materials and
construction taught by Johnson, Langworthy and Ambrosio and
