The number of design processes for fabricating semiconductor devices can be reduced by parallel connection of a plurality of unit bipolar transistors Qu that are completely electrically isolated from each other in a semiconductor layer of an SOI substrate 1 to form a bipolar transistor having a large current capacity. M summing modules sum portions of each of the M modulated and multiplexed data streams to generate M transmit data streams. Positioning the collar relative to the spinning fuselage produces a direct lift force on the projectile that may be used to steer the projectile.
