Well, here's what Babelfish says:
(I'm still confused...)

CXAll29N is the new monolithic reception electric circuit which Japan
Sony Corporation produces, it integrated the amplitude modulation,
frequency modulation stereophonic receiver all functions, and consumes
the electricity province, with fifth battery power supply, may use for
a month. This IC is 30 feet 双列 flat plastics seal, the volume is very
small, the length is 10mm, the width only has 5.smm. The attached
figure is CXAll29N assembly AM/the FMSTEREO radio electric circuit
schematic diagram, the working voltage is 1.5V, the operating current
is 8mA. CXAll29N 2nd, 30 feet respectively are center the wave and the
frequency modulation antenna signal input end; The 7th foot is hanging
when is the FM receive condition, meets V+ is the AM condition; IC2
(4,537) is the necessary audio frequency amplification electric
circuit, its 2, 4 feet respectively be audio frequency about sound
track input end; 8th foot earth; 7th, 9 feet are the audio frequency
out-ports, may directly impel the low impedance earphone. This machine
antijamming ability strong, receiving sensitivity high, when listens
to the frequency modulation program, the sound is clear but the
background sound to be much more static, its acoustic fidelity
approaches the CD level. If can use the upscale earphone to listen to,
some large-scale combined sounds also are unable with it comparison.
