Abstract: In a stator for a rotating electrical machine, a stator core, and a stator winding are provided. The stator winding is located in or around the stator core and has a coil end exposed outside a corresponding end of the stator core. A neutral busbar is connected to the coil end of the stator winding, and a temperature sensor is mounted to the neutral busbar. A resinous seal includes an insulating resin, and the insulating resin of the resinous seal is arranged to cover an axial end portion of the coil end and the neutral busbar. The resinous seal is configured to have bubbles formed in the insulating resin. The bubbles are located around the neutral busbar.

Abstract: A PLC system includes a programmable logic controller including a PLC unit and a storing unit and an arithmetic-expression-data-creation supporting apparatus causing the PLC unit to create arithmetic expression data of an arithmetic expression to be executed by the PLC unit, and the arithmetic-expression-data-creation supporting apparatus includes an input unit to receive, from a user, the arithmetic expression including input information serving as a variable used in an arithmetic operation and a constant used in the operation and an arithmetic-expression processing unit to obtain a calculation sequence of the expression, and the storing unit retains an arithmetic-expression-data table for managing the arithmetic expression data including the input information, the constant and the calculation sequence, and the PLC unit includes an operation unit connected to the storing unit, to execute an arithmetic operation of the arithmetic expression according to the calculation sequence using the input information and
