The adder has at least one data reduction stage, each data reduction stage having at least one multi-column full adder.

A further size reduction step may also be employed.

A gear train (21) having a variable transmission ratio is mounted before the gearing fitting.

The drive unit comprises an electric motor and a drive train comprising a reduction stage with an output shaft.

The adjustment device comprises a drive unit, situated in a housing, which has a motor and a drive train with reduction stage.

The electric motor driving each cutting unit comprises a brushless motor having an integrated gear reduction stage.

The teeth of the different members are continuously in mesh with a given reduction ratio which is determined between the teeth of the outer members and/or by at least one reduction stage inside the intermediary member.

The rotating movement initiated by the rotating element is translated into a rotating movement with a larger angle of rotation by means of a translation step.

LVDS data from a DVI source is decoded into parallel word format and passes through a colour space reduction stage before being stored in a frame buffer.

The system also includes an external reduction stage located outside the transmission housing and driven by the first motor shaft to rotate the input/output shaft.

Each of those outputs is coupled to a secondary reduction step (30; 40), consisting of a worm (31; 41) and a worm wheel (32; 42).

The adder has at least one data reduction stage, each data reduction stage having at least one multi-column full adder.

If a second stage is used as a reduction stage, then a pre-reduction stage may be added.

Each pressure reduction stage communicates with another pressure reduction stage in an adjacent one of the annular plates in the stack.

The second-stage reduction section (102) is disposed at the outer peripheral section of the first stage-reduction section (101).
