Abstract: A method of manufacturing a micro-oscillator includes: preparing a substrate having a flat portion and a curved surface portion formed in a three-dimensional curved shape protruding from one surface of the flat portion, the curved surface portion being surrounded by the flat portion; and irradiating an outer surface of the curved surface portion with a laser beam to separate the curved surface portion from the flat portion.

Abstract: A drive apparatus is provided for driving a multi-phase rotating electric machine. The rotating electric machine includes a plurality of winding groups for respective phases. The drive apparatus includes a first inverter connected with start terminals of the winding groups of the rotating electric machine, a second inverter connected with intermediate terminals of the winding groups, and an energization controller configured to selectively perform energization of the winding groups by the first inverter and energization of the winding groups by the second inverter. Each of the first and second inverters includes a plurality of switch pairs respectively corresponding to the winding groups and each consisting of an upper-arm switch and a lower-arm switch that are connected in series with each other. Moreover, each of the upper-arm and lower-arm switches of the first inverter is configured to have bidirectionally-conducting and bidirectionally-blocking functions.
