This edition of the series of programs explaining the technology used to produce items that are familiar in our daily life features ‘Elevators’.

The 'car' people ride in is an assembly of components made from large steel plates. The program introduces the rarely seen production process of electronic devices, such as the ‘control panel’ and the ‘operation panel’.
