ルネサス那珂工場で発煙　３時間半後に生産再開

　半導体大手ルネサスエレクトロニクスは２１日、火災発生で一時生産を停止していた那珂工場（茨城県ひたちなか市）で午後４時半ごろに発煙があったと発表した。社員が鎮火し、約３時間半後に生産を再開した。同社は「今後の生産や出荷の見通しに影響はない」としている。人的被害もなかった。
　同社によると、現場は３月に火災が発生したのと同じ建物で、１７日に生産を再開したばかりだった。発煙したのは、製造途中の製品を運ぶ自動搬送台車を動かす床下の電源盤。発煙の原因は電源系統のトラブルで、前回の火災と関係性はないという。消防などが現場を詳しく調べ、原因を特定する。（2021/04/22-00:35）

Renesas Electronics Corp. said Wednesday that smoke broke out around 4:30 p.m. the same day (7:30 a.m. GMT) at its flagship semiconductor plant in eastern Japan, which was hit by a fire last month.
   Employees of the company contained the situation, and production resumed about three and a half hours after the incident, according to the major Japanese chipmaker.
   The incident will have no impact on future production and shipments at the Naka plant in the city of Hitachinaka in Ibaraki Prefecture, Renesas officials said, adding that no one was injured in the smoke incident.
   The smoke came out of a power panel under the floor at the plant's N3 building, where the March 19 fire occurred. The power panel is for operating a rail-guided vehicle used to transport semiconductors in the manufacturing process.
   A problem in the electrical system led to the smoke, and it is not related to the cause of the March fire, the officials said. A local fire department and others will investigate the incident to determine the cause of the smoke.
