    摘要: A brushless DC motor which can be started positively by using a single position detecting element. The motor has a starting circuit which forcibly energizes the stator coils thereby to start rotating the rotor. The position detecting element produces n position signals corresponding to n positions of the rotor at which a specific stator coil is to be energized. When the position detecting element produces one of the n position signals, the motor begins to energize the stator coils according to position signals obtained from counter electromotive forces generated in the stator coils. Further, one of the n position signals produced by the position detecting element is made different from the other, a reference position signal can be obtained.

    摘要: A temperature determination apparatus includes a signal detection section having an A/D input port, a thermistor that is connected to the A/D input port and outputs an analogue signal to the A/D input port, and a switch section that shifts a level of the analogue signal to a low level. The signal detection section determines that a control signal having a priority higher than that of an output detection process of the thermistor is generated when it is detected that the analogue signal to be input to the A/D input port is in the low level.

    摘要: Disclosed is an audio system including a group of loudspeakers that form a sound field by delivering into a single space sound signals passed through respective ones of a plurality of sound signal channels. This audio system is comprised of two characteristic-variable equalizers that are cascaded to each other to constitute a part of the sound signal channels; a sound field characteristics detecting part for supplying test signals through the sound signal channels and detecting sound pressure in the sound field and thereby obtaining a sound pressure signal; and a characteristics adjusting part for adjusting, based on the sound pressure signal, equalizing characteristics of the characteristic-variable equalizers individually and with respect to each of the sound signal channels. The sound field characteristics detecting part selectively generates test signals of different bands. The characteristics adjusting part adjusts equalizing characteristics of either one of the two characteristic-variable equalizers according to the band of the test signal.
