Mitsubishi Electric Corporation puts the maximum effort into making semiconductor products better and reliable, but there is always the

possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, appropriate measures such as

(i)placement of substitutive, auxiliary, circuits, (ii)use of non-flammable material or (iii)prevention against any malfunction or mishap.
