The production of finely-tuned optical lenses and prisms - used in cameras, telescopes and semiconductor manufacturing equipment - necessitates the sensitive touch of the human hand. Akira Hozumi produces prototype optical lenses and pentaprisms, which then become the standard for mass-produced goods. He uses his hands, fingertips and a sense of timing and intuition that has been honed over the years to produce these articles, some with angles to within 1/360 of a degree.

The shape of a particular fiber determines its distinctive qualities, and central to the distinctiveness of each fiber is the precision of the holes, which can be as small as 100 microns, through which petroleum-based materials are squeezed to become chemical fibers. Akinori Katayama has been designated a "modern master craftsman" by the Ministry of Labor. He files and polishes unique tools made of ultra-hard alloys up to the thickness of a strand of human hair that are used to drill these holes into nozzles.

ハイテクの職人たち | ミクロの研磨 巨大スクリュー [NHK]
|Length : 10min. |Year : 1998 |
This episode focuses on the process of making giant ship propellers - from the initial stage when the copper alloy is cast into the mold, through the final steps which require manually planning the hole in the propeller where the shaft must be snugly fitted, to the hand polishing of the giant blades. These "human touches" ensure that the ships which transport goods around the world can journey efficiently and safely. To paraphrase Mr. Izutani who has been doing this job for 25 years: "Humans are still superior to machines."

In the summer of 1993, it was the Tokyo Institute of Technology's turn to host the International Robot Contest. This contest has been held every year since 1990 at some of the world's most top-ranked universities and institutes, including MIT. This time, there were eight teams of six people, each team fielding a robot with advanced manipulatory skills. The test in this hi-tech sport was to put tubes into a box with two openings just big enough for the largest of the tubes.

Atomic bomb survivor and former elementary school teacher Kajiya Fumiaki, age 85, holds a special class at an Osaka elementary school. He was six years old when the bomb fell, at school just 1.8 km from the epicenter. His sister, who was with him, was killed. Kajiya uses a picture-card show he drew himself to explain what happened that day and brings a special object to share with the class. With an operation for bowel cancer looming, what final lesson will Kajiya teach the children?
