New Radar Has 500-Foot Range
Designed for automobile obstacle detection at ranges up to 500 feet, a new and
simple radar method is capable of working at ranges down to a few inches, according
to Wesley D. Boyer of the Ford Scientific Laboratory. The equipment, described by
Mr. Boyer in a paper read at the latest IRE convention, is a single microwave transmitter,
using one tube. It is switched (diplexed) alternately between two frequencies. The
receiver compares the phases of the two alternately produced Doppler frequency waves
to obtain the range of the obstacle reflecting the wave. The device might also be
useful, said Mr. Boyer, as an aircraft altimeter.
Japanese Production Up
Japanese electronics production increased roughly 20% in value in 1961, as over
1960. The figures, based on the first 9 months of each year, were released by the
Dept. of Commerce, Television and radio receivers accounted for 48% of the 1961
production. TV receivers alone, for the 9-month 1961 period, amounted to 3,195,000
units, compared to 2,583,000 in the 1960 9-month period. Transistor receivers were
up from 8,101,000 to 8,899,000. All semiconductors showed a significant increase,
with transistors going from 104,377,000 to 129,947,000. Significantly, the value
in thousands of dollars decreased during the same period, from $53,847,000 to $39,929,000,
reflecting a sharp drop in transistor prices.
Sigmund Loewe Passes
Dr. Sigmund Loewe, radio and television engineer and inventor, died May 2 in
Sarasota, Fla. Dr. Loewe was one of the earliest experimenters with television,
and in connection with these early experiments. Dr. Loewe invented (in the late
'20's) the first multiple tube, combining three tubes as well as coupling resistors
and capacitors in a single envelope. This was done in connection with the search
for a low-noise, wide-band amplifier for video signals.
At the time of his death, Dr. Loewe was president of the Loewe Radio Co. of New
York, the Andromeda Co. of Switzerland and Loewe Radio Ltd. of London. His age was
76.
