Nidec Copal to Make Copal Yamada Consolidated Subsidiary

KYOTO, Japan, July 22, 2008 (PRIME NEWSWIRE) -- Nidec Corporation (NYSE:NJ)
today announced that one of its consolidated subsidiaries, Nidec Copal
Corporation ("Nidec Copal") (Tokyo Stock Exchange:7756), resolved today to
purchase new shares issued by its equity method affiliate, Copal Yamada
Corporation ("Copal Yamada"), through a third-party allocation. Following this
new share allocation effective August 1, 2008, Copal Yamada will become a
consolidated subsidiary of Nidec Copal.

Copal Yamada is a fifty-fifty joint venture established in July 2003 between
Nidec Copal and Apic Yamada Corporation (Tokyo Stock Exchange:6300) and
specializes in the design and manufacture of precision molds. Copal Yamada will
issue 3,500 new shares of its common stock at 50,000 yen per share through a
third party allocation to raise 175 million yen, increasing its total number of
shares issued from 6,000 shares to 9,500 shares. Nidec Copal will then acquire
all the newly issued shares to increase its stake in Copal Yamada from the
current 50% to 68.4%.

By owning a majority stake in Copal Yamada, Nidec Copal intends to better align
Copal Yamada with its strategic initiatives that focus on enhancing the speed
and size of the mold business to meet the increasing overseas demand.

Nidec Copal expects the said new share allocation and the resulting inclusion of
Copal Yamada into its scope of consolidation will have a minimal impact on its
financial results for the current fiscal year ending March 31, 2009.
