Abstract: An expansion valve device has a housing, a valve body, an actuator, a first, second, and third detectors, and a controller. The housing defines a first refrigerant path and a second refrigerant path therein. The first detector detects a temperature of the refrigerant flowing in the first refrigerant path. The second detector detects a temperature and a pressure of the refrigerant flowing on an upstream side of the valve body in the second refrigerant path. The third detector detects a temperature or a pressure of the refrigerant flowing on a downstream side of the valve body in the second refrigerant path. The controller calculates a flow rate of the refrigerant flowing in the second refrigerant path and a superheating degree of the refrigerant flowing in the first refrigerant path, and controls the opening degree of the valve body such that the superheating degree falls within a specified range.

Abstract: A power supply terminal structure includes: a circuit board; and a power supply terminal having a pair of terminal parts projected from the circuit board. The pair of terminal parts has: a retaining part that retains by clamping a terminal of a motor; a guide part located above the retaining part; and an elastic deformation part located below the retaining part. An interval between tip ends of the pair of terminal parts is increased as extending upward, and the guide part is displaced to increase the interval when the terminal of the motor is retained by the retaining part. The elastic deformation part is elastically deformable to displace a tip end of the guide part, and is curved to protrude in the width direction. The pair of terminal parts is separated from a convex part of the motor in a retaining state.

Abstract: When a control device of a motor controller simultaneously rotates a first DC motor and a second DC motor by controlling a first circuit, a second circuit and a third circuit, the second circuit is shared. Further, the control device controls each of switch elements of the shared second circuit by using pulse-width modulation. Accordingly, the drive of the first DC motor and the second DC motor can be controlled with high accuracy by the change of a duty ratio of each of the switch elements of the shared second circuit.
