Abstract: A controller that controls an electric compressor, which is mounted to a vehicle and configures a two-stage compression refrigeration cycle device, has a deceleration section, an operation stop section, and a restart section. The deceleration section reduces a rotational speed of an electric motor by controlling an AC current which is output to the electric motor, when a two-stage compression mode, in which an intermediate-pressure refrigerant flows into the electric compressor from an intermediate-pressure port, is performed and an operation stop request to stop the electric compressor is made. The operation stop section stops the electric motor after the deceleration section reduces the rotational speed of the electric motor. The restart section restarts the electric compressor when the operation stop request is canceled after the operation stop section stops the electric compressor.

The second casing includes a discharge passage in which a high-temperature fluid compressed by the compression portion flows. A limiting structure that limits the heat transfer from the fluid flowing in the discharge passage is provided between one of the electronic components and the discharge passage. The limiting structure includes a seat portion that defines a gap between a bottom surface of the one of the plurality of electronic components and the discharge passage. According to the electric compressor, the heat transfer from the fluid to the electronic components can be limited.

Abstract: An air conditioner for a vehicle has a compressor, a radiator, a first pressure reducer, a gas-liquid separator, a second pressure reducer, an exterior heat exchanger, an intermediate pressure refrigerant passage, a switching device, and a controller. The controller operates the switching device to switch from a refrigerant circuit of a two-stage compression mode to a refrigerant circuit of a single-stage compression mode when a compressor stop signal is output in the two-stage compression mode. The single-stage compression mode is a mode that blocks at least a flow of an intermediate-pressure refrigerant into the intermediate pressure refrigerant passage and makes refrigerant remained in the intermediate pressure refrigerant passage to flow out of the intermediate pressure refrigerant passage. The controller stops the compressor after controls the compressor to continue operating for a specified time in the single-stage compression mode.

Abstract: When a call is issued from a first analog telephone set (101S) to a second analog telephone set (101R) by utilizing a public telephone line network (107), a second Internet connecting device (103R) senses an incoming call, then stores a telephone number of the first analog telephone set (101S), and then sends out a sender-side telephone number and a receiver-side telephone number as an IP packet to the Internet (105) to direct to a predetermined multicast address. A first Internet connecting device (103S) disconnected the calling when it receives the IP packet, then both Internet connecting devices (103S), (103R) are caused to recognize sender-side and receiver-side IP addresses by transmitting the IP packet to a destination-side IP address via the Internet (105), and thus a voice talking via the Internet (105) is established. Accordingly, the Internet phone system can be built up with a simpler means structure and also a voice quality can be maintained.
