摘要： A fault diagnosis method for a roller conveyor including rollers, brushless motors, and zone controllers for controlling the brushless motors, the brushless motors and/or the rollers each having a rotation detector, the zone controllers each having a driver containing a logic circuit, a memory, which contains a program, and a micro computer is proposed. The program includes a fault diagnosis program and a criterial parameter. The zone controllers each obtain an operating parameter of the brushless motors and/or the rollers so as to perform comparison of the operating parameter with the criterial parameter and determine a failure of the roller conveyor in a case where a result of the comparison is above a predetermined level.

摘要： A conveyor, which has an area in its conveyor line and for adjusting intervals between articles, includes (1) a plurality of zones constituting the area and each having at least one driving motor and an article sensor, (2) structure for measuring either an interval between adjacent articles in the conveying direction or a difference of time points when adjacent articles in the conveying direction pass the sensor, and (3) a motor controller for each of the zones and for varying a rotational speed of the driving motor. When the measuring structure measures either the interval or the difference upon reception of signals from the sensor, the motor controller either accelerates or slows down the rotational speed of the driving motor in a zone where the article is placed.

摘要： A brake-controllable brushless motor has a rotor and a stator having polyphase coils; a polar position detector whereby electric power is supplied to the coil selected by its phase in response to the polar positions of the rotor detected by the polar position detector; a driver division for controlling the electric supply to the coils; a motor pulse identifier for recognizing motor pulse signals fed from the polar position detector; and a delayed pulse generator for producing phase-delayed pulse signals in response to the pulse signals fed from the motor pulse identifier, thereby ensuring that when the brushless motor is braked, the phase delay of the delayed pulse signals is progressively and continuously enlarged, and that the coils receive a controlled electric supply from the driver division in response to the delayed pulse signals.

摘要： A static random access memory (SRAM) includes a memory array, a sense amplifier circuit, a replica circuit and a dummy cell. The replica circuit has the same elements as memory cells, and includes plural replica cells which output a signal whose level corresponds to the number of stages provided to a common replica bit line. The dummy cell is connected as a load with the common replica bit line. The source of a drive transistor of the dummy cell is connected with a power source which is at the High level. This suppresses a leak current flowing from a replica bit line to the dummy cell.
