Abstract: A control system of a tape feeder that includes a reel on which is wound component supply tape, and a tape feeding device configured to draw out the component supply tape from the reel to a component pickup position, the control system including a sensor configured to detect information relating to a remaining amount of the tape on the reel; and a motor control section configured to change an operation parameter of a motor that is a drive source of the tape feeding device based on the tape remaining amount information detected by the sensor. Specifically, the motor control section changes the operation parameter of the motor so as to reduce the motor torque as the tape remaining amount on the reel decreases, based on the tape remaining amount information detected by the sensor.

Abstract: In the case where multiple individual work devices respectively executing a sequence of multiple tasks are controlled in an integrated manner by an integrated control device, log analysis among the multiple individual work devices is difficult. One of four individual work devices transmits time inquiry signal to main integrated control device via serial communication cable. Main integrated control device returns the time at time at which time inquiry signal was received to the one of four individual work devices to which time inquiry signal was transmitted. One of four individual work devices receives a reply from main integrated control device at time, adds the communication time to the time at time, and calculates the time at time. One of four individual work devices starts the calculation of the in-device time from calculated time as a starting point. One of four individual work devices logs based on in-device time.

Abstract: In an optical connector 1, a cord receiving hole portion 11c, where an optical fiber cord 90 can be inserted and received axially of the optical fiber cord, is formed in a housing 10. A mounting hole 13, through which a stopper 40 can be inserted into the portion 11c perpendicularly to an insertion direction of the cord 90, is formed in the housing. A positioning slit 42, having a width slightly smaller than the diameter of the cord 90, is formed in each plate-like portion 41. A blade portion 43 with an angle 90° is formed at each open end of the slit 42. When the stopper 40 is inserted into the portion 11c through the hole 13, each portion 43 abuts against a covering portion 92, and penetrates into the portion 92 while forcing a cut portion of this portion 92 away in the stopper insertion direction.

Abstract: A PWM signal generation circuit and a PWM control circuit are provided in which the duty ratio is easily changed and which can also avoid adverse impact from ambient temperature changes and the like. At the beginning of charging a capacitor with a current flow, a voltage level at a connection point between the negative input terminal of a comparator and the capacitor is still below a charging threshold. When the charging threshold is exceeded, the comparator is inverted to a low state and a current flows into an output point of the comparator to start discharging the capacitor. At the beginning of discharging from the capacitor, the voltage level at the connection point is still above the discharging threshold. However, when the voltage level falls below the discharging threshold, the comparator returns to a high state, and the charging operation again takes over.
