    • An improved cooling mechanism for a power electronics device is provided. More specifically, a cooling mechanism is provided that includes an air passageway configured to allow cooling air to bypass a portion of a heatsink adjacent to the rectifier circuitry and direct cooling air into an area of the heatsink that is nearer to the inverter circuitry. Another embodiment employs an air passageway with an air directing structure configured to provide an air flow that impinges on a lateral surface of the heatsink. In another embodiment, the air directing structure is chosen to provide a turbulent air flow in the heat dissipating structure within the vicinity of the inverter circuitry.

    • A laser processing method which can efficiently perform laser processing while minimizing the deviation of the converging point of a laser beam in end parts of an object to be processed is provided.
      This laser processing method comprises a displacement acquiring step (S06 and S07) of acquiring a displacement between a point on the line to cut and one end of the line to cut in the object while irradiating the object with a second laser beam, converged by a lens, for measuring the displacement of a main surface of the object; and a position setting step (S08 and S09) of setting an initial position for holding the lens with respect to the main surface of the object according to the acquired displacement, and holding the lens at thus set initial position. After a modified region is formed in one end part of the line to cut by irradiation with a first laser beam for processing while holding the lens at the initial position, the lens is released from being held, and then the modified region is formed while adjusting the position of the lens.
