摘要： A hairbrush incudes a body, the body having a first brush with a through-hole on its surface and a second brush without a through-hole on its surface, and the body further having a passage in which hairdressing is flowed, wherein one end of the first brush is connected to the passage and the other end is exposed; a grip, the grip having a container for storing hairdressing; and a pump for sending the hairdressing stored in the container to the first brush via the passage.

摘要： A motor drive control device for controlling the driving of a brushless motor includes position detecting units (e.g. sensors or Hall elements), a drive signal determining unit and a drive signal outputting unit (an output circuit). The position detecting units are disposed in positions apart from each other by an electric angle of 120 degrees and output position detection signals representing the position of the rotor with respect to the stator. The drive signal determining unit determines drive signals for driving the 3-phase drive coils on the basis of the position detection signals. The drive signal outputting unit generates and outputs, to the 3-phase drive coils, the drive signals that have been determined by the drive signal determining unit.
