Provided are a method of making irbesartan via a Suzuki coupling reaction and a novel intermediate, 2-butyl-3–1,3-diazaspiro4. The solder bumps are preferably about 10 microns in diameter, and the pitch between the solder bumps is less than 100 microns, and preferably less than or equal to 10 microns. The axial gap type rotating machine includes a rotor fixed to an end of the crank shaft that extends outside of the crank case and a stator fixed to the crank case and facing the rotor.
