The speed of sound Sound waves are longitudinal mechanical waves that can travel through solids, liquids, or gases. The speed of a sound wave in medium(having bulk modulus(容变弹性模量)and density p) is:

Patented free-floating silicon technology Low on-state and switching losses Optimized for use as freewheeling diode in GTo converters Standard press-pack housing, hermetically cold-welded Cosmic radiation withstand rating
The Bipolar Junction Transistor The term Bipolar is because two type of charges (electrons and holes) are involved in the flow of electricity The term Junction is because there are two pn Junctions There are two configurations for this device n-type p-type n-type
he World's Largest-Capacity 8kV/3.6kA Light-Triggered Thyristor by Katsumi sato* Mitsubishi Electric has developed an 8kV/3.6kA light-triggered thyristor (LTT) based on a six inch wafer for power-converter applications in igh-voltage DC transmission and back-to-back systems. New design features give the device
