Major DfE Accomplishments
In 2006, we pursued DfE (designs for environment) through fundamental material review, efforts
to shorten production lead-time, component unitization, and LCA (life cycle assessment). We will
continue to develop high quality products that are environmentally friendly. |

The optical performance of the
195YA model is highly regarded
by our customers. Therefore, in
designing the new 395YA model,
my task was to renew the barrel
design while maintaining optical
system performance. Pursuing DfE
presented a number of constraints.
As a result of repeated trial and
error, we reduced weight and saved
energy in manufacturing through
employing injection molded plastic
parts in lieu of metallic parts as
key components. By introducing an
iris that can be replaced as a unit
when repairing, work improvement
was made too. Durability was also
increased for a longer service life. |
