Rare earth sintered magnets for compact and high power motors

Motor, one of major parts of hybrid cars, is for driving electromagnetically, equipped with rotors with permanent magnets and it rotates synchronizing with a frequency of 3 phase AC. Hybrid cars require lighter motors with higher power. The permanent magnet used for them are neodymium* sintered magnets because they have strong magnetic force with compact body. The neodymium sintered magnets are expected to grow in markets where such motors with compact body and high performance are requird.
*Neodymium (Nd) = Rare earth metal. Atomic number 60. Atomic weight 144.2. Lanthanide.

Power supply IC for controlling high voltage (Ultra Thin Wafer)

Power supply IC for hybrid car is used for controlling high voltage and high current. Higher "integration" would cause discharge and the power supply IC requires heat radiation function. Some power supply ICs are made from "Ultra thin wafers" in order to supply high current with low electricity loss.

	Deposition system that has solved problems such as "wafer break or warp" and "wafer overheat during process".
	Sputtering System SRH-420MC
