Abstract: PROBLEM TO BE SOLVED: To solve the problem that the start-up time of a brushless motor is increased in a controller which is equipped with a positioning means that controls the rotating angle of the brushless motor at its final angle through an intermediate angle. SOLUTION: The controller controls the rotating angle at a first positioning target angle by first positioning in which a current is applied from specific one phase to the other phase, and then, controls the rotating angle at a second positioning target angle by second positioning in which a current is applied from one phase to the other phase while changing the phases. The duration (a first given time T1) of the first positioning is set as follows. The first given time T1 is set so that the amplitude of the vibration of the rotation angle becomes smaller than the angle interval between the first positioning target angle and the dead point of the second positioning process in damped oscillation in the vicinity of the first positioning target angle by the first positioning.

Abstract: PROBLEM TO BE SOLVED: To accurately set an angle for a switching operation based on zero cross timing in which an induced voltage of a rotating electric machine becomes a reference voltage when a rotational speed varies in controlling the rotating electric machine by operating switching devices for a power converting circuit. SOLUTION: For the specified timing which is delayed by a predetermined angle from the zero cross timing in which the induced voltage of a brushless motor 10 meets the reference voltage vref, the switching devices SW1 to SW6 are switched. At this time, a prescribed time from the previous zero cross timing to the specified timing is set based on the interval of the previous two zero cross timings. However, the required time is corrected corresponding to the variation amount when the rotational speed of the brushless motor 10 varies. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a transceiver device reducing a noise generated accompanying communications.
SOLUTION: In a transceiver 21 at a master side and transceivers 22-25 at a slave side, each connected to a network for an automobile, each communication rate detection circuit 27 detects a communication rate by measuring the specified period of time in the synchronous field of reception data outputted from a reception circuit 11. Each gradient generation circuit 33 generates a trapezoidal wave-like driving instruction signal by using a CR integrating circuit, where, the trapezoidal wave-like driving instruction signal is generated by dulling the a change in the edge of transmission data. Thus, the rate of change of a data signal on a communication bus 3 is automatically adjusted to a value complying with the actual communication rate to reduce the rate of change of the edge when the communication rate is set to a low value, reducing the noise (radio noise) radiated from the communication bus 3.

Abstract: PROBLEM TO BE SOLVED: To provide a load drive circuit capable of not turning off the current, upon detecting abnormal temperature, to protect plural switching elements adjacent to each other without by keeping the current in the switching elements normally operating. SOLUTION: In this load drive circuit 1, when two transistors, the 1st transistor 11 and a 2nd transistor 21 adjacent to each other, simultaneously become abnormal by high in temperature due to an abnormal one of them, a temperature comparison circuit 61, first, identifies the high temperature transistor and a protection circuit 71 stops the drive instruction from the gate drive circuit responsible for the transistor involved therein. This can suppress the temperature rise caused by the transistors in abnormality, protecting them from breaking due to high temperature. Further, since the normal low temperature transistors continue their current without interruption, the load drive control can be kept on. Thus this circuit's control is not deteriorated.
