Abstract: A driver for motors according to the present invention is provided with: an aluminum substrate (10) which forms one surface of a housing; an insulating layer (11) which is formed on a surface of the aluminum substrate (10); a plurality of electronic elements (13) which are bonded onto a surface of the insulating layer (11), said surface being on a side opposite to the aluminum substrate (10); and a resin member (14) that covers the surface onto which the electronic elements (13) are bonded. This driver for motors is characterized in that the resin member (14) is obtained by integrating a mold resin part (20) which covers the electronic elements (13) from the upper surface side, a connector (21) which is electrically connected to the electronic elements (13), and a fitting part (22) which is used for fitting to a motor.

Abstract: A processing apparatus includes a holding table and a processing unit. The processing unit includes a spindle unit having a spindle and a housing in which the spindle is rotatably supported. The processing unit is connected to a spindle temperature adjusting unit for adjusting the temperature of the spindle unit to a predetermined temperature. The spindle temperature adjusting unit includes a circulation route through which a cooling liquid to be introduced into the housing circulates and a heat exchanger connected to the circulation route. The heat exchanger is supplied with a processing liquid, to lower the temperature of the cooling liquid flowing in the circulation route with the processing liquid and increase the temperature of the processing liquid with the cooling liquid.
