Abstract: A production system includes a cell control apparatus that is connected to a machine control apparatus and an inspection control apparatus. The cell control apparatus includes a storage part that stores data on a state of the manufacturing machine, data on an environment state, and data on an inspection result of a product. The cell control apparatus includes a correlation analysis part that selects a variable relating to an abnormality based on a correlation between the inspection result of the product, and the data on the state of the manufacturing machine and the data on the environment state when the abnormality occurs in the inspection result, and a determination value setting part that sets a determination value of the variable relating to the abnormality.

Abstract: A conduction path structure of a robot in which a conduction path has a simplified structure is provided. A conduction path structure of a robot includes: a structural mechanism which functions as a support and has a conductor portion; an actuator that operates the structural mechanism; and a conduction path through which driving power and/or a control signal is supplied to the actuator, wherein the conduction path also serves as the conductor portion of the structural mechanism.

Abstract: A robot includes a motor drive power source for converting a voltage supplied from a power source to a motor drive unit-grade voltage and outputting it, a motor drive unit for converting a motor drive unit-grade voltage output from the motor drive power source to a motor drive voltage and outputting it, a motor driven to be rotated by a motor drive voltage output by the motor drive unit, a robot arm on which the motor drive unit and the motor are arranged, and a robot controller which is provided independently of the robot arm and on which the motor drive power source is arranged.

Abstract: A motor drive according to the present invention has a dynamic braking circuit. The motor drive includes a motor drive control circuit for applying a voltage to windings of a synchronous motor and the dynamic braking circuit for a predetermined time by switching power transistors connected to a direct current power supply, a current detection circuit for detecting a current value outputted from the power transistor, and a failure determination circuit for determining the presence or absence of a failure in the dynamic braking circuit from the current value detected by the current detection circuit and a predetermined threshold value. When the presence or absence of a failure in the dynamic braking circuit is detected, the resistance of the dynamic braking circuit is changed.

Abstract: An adhesive composition contains a polyurethane-polyolefin complex composed of a polyurethane having a first functional group and a polyolefin having a second functional group that reacts with the first functional group. The polyurethane and the polyolefin is bound by a reaction between the first functional group and the second functional group.
