Abstract: An air conditioning device for a vehicle includes: a refrigeration cycle including a compressor, a condenser, an expansion valve, and an evaporator through which a refrigerant is sequentially flowed; a high-temperature heat medium circuit through which a high-temperature heat medium has exchanged heat with the refrigerant in the condenser is circulated; a low-temperature heat medium circuit through which a low-temperature heat medium has exchanged heat with the refrigerant in the evaporator is circulated; a connection line connecting the high-temperature heat medium circuit to the low-temperature heat medium circuit; vehicle interior heat exchangers allowed to be introduced the heat medium thereinto; and a switching unit which switches an operation state of the air conditioning device to a first mode allowing to connect the vehicle interior heat exchangers to the high-temperature heat medium circuit, a second mode allowing to connect the vehicle interior heat exchangers to the low-temperature heat medium circ

Abstract: An industrial robot may include multiple motors structured to rotate multiple arm units; multiple motor drivers to drive multiple motors; a power source to supply power to the multiple motor drivers; a charge-discharge unit connected to the multiple motor drivers; a control execution unit to control the multiple motor drivers; an elevation motor to elevate the arm, an elevation motor driver to drive the elevation motor; a first brake to stop the elevation motor; and a second brake to stop the elevation motor. When the industrial robot makes an emergency stop, the supplied power is turned off and control execution unit stops the multiple motors while controlling the multiple motor drivers by using the power supplied from the charge-discharge unit. The control execution unit controls at the time of said emergency stop, operates the first brake and then operates the second brake to stop the elevation motor.

Abstract: The present invention is to provide an industrial robot, which is placed in vacuum for use, capable of efficiently cooling down hand- or arm-driving motors which are arranged inside the arm in air. The industrial robot is provided with a motor for rotating a second arm unit with respect to a first arm unit, a motor for rotating a hand with respect to the second arm unit, a reduction gear for reducing the rotation of the motor and transmitting it to the second arm unit, and a reduction gear for reducing the rotation of the motor and transmitting it to the hand; the hand and the arm are placed in vacuum. The reduction gears and are coaxially arranged so that the center of rotation of the second arm unit with respect to the first arm unit coincides with the axial centers of the reduction gears. The interior space of the hollow first arm unit is kept at atmospheric pressure in which the motors and the reduction gears are arranged.
