Having a high energy density per unit volume, the large
electric capacity of these batteries is about twice that of
alkaline-manganese batteries. Moreover, their voltage
characteristics are stable, so they are mainly used in quartz
watches, which require high accuracy, but they are also
used in other precision devices, such as clinical
thermometers.
Manufactured by an integrated process extending from raw
materials to finishing, our DIANET is a samarium-cobalt
(SmCo) magnet offering high performance, accuracy, and
quality.
DIANET is used in stepping motors for wristwatches, but it is
used in other, ever expanding, applications, including micro-
electronic parts for audio and telecommunications devices;
reflow-mounted thin, compact devices; and microelectrome-
chanical systems (MEMS).

Our special metal materials were originally developed as
springs for mechanical watches. Their superior properties of
elasticity, durability, corrosion and heat resistance
allow them to be used in a broad spectrum of fields,
including medical materials, small precision springs,
and metallic diaphragms.
From the smallest and thinnest heat-resistant reflowable
batteries, we offer a wide product lineup to meet market
ranging needs. The quality and reliability of our
rechargeable batteries are so high that they enjoy the
market share in the world. They are used in a broad wide
range of applications, such as cell phones, digital cameras,
Portable GPS, and others.
