The Beginning of booming consumer economy

In the 1950s, as the Japanese electronics industry continued to grow, many broadcasting stations were established, with public radio broadcasts beginning in 1951, and television broadcasts beginning in 1953.

The dawn of the radio and television era was the construction of a microwave communication network by NTT Corporation (Nippon Telegraph and Telephone Public Corporation, the predecessor of the current NTT group). Not just communications companies, but all of society benefited from the booming consumer economy of 1950 to 1953.

At the same time, orders took off for hand-powered generators and radio power supplies, and production at our Ueda Works was extremely busy. Hand-power generators were a necessity for powering lifeboat radios in the event of an accident. Much of the demand for these products, which would later be legally mandated, was met by SANYO DENKI.
We also received orders from the Defense Agency for portable gasoline generators. These were used as power supplies for portable communications units, such as were carried in trailers.
In addition to such large orders, there was high demand for power supplies for emergency marine radios and for converters for fish detectors, and high production at Ueda Works continued into the latter half of the 1950s.
