A transmission device includes a transmission line composed of first and second transmission lines. A first circuit block outputs a non-inverted transmission signal to the first transmission line, and a second output circuit outputs an inverted transmission signal to the second transmission line. The second circuit block comprises an impedance element and a comparison circuit for comparing voltages. The same types of impedance elements as the impedance element are interposed in the first and second transmission lines between the first circuit block and the second circuit block.

Transmission device for transmitting a signal through a transmission line between circuits blocks having different power supply systems

According to the present invention, even when the two-layer mode in which the inside air is introduced into a first air passage and the outside air is introduced into a second air passage is set, it is further determined whether air mix doors are controlled at the maximum hot positions. When it has been determined that the air mix doors are controlled at the maximum hot positions, the inside/outside air introduction mode is still set to the two-layer mode, because the temperature difference due to the outside air temperature is small, however, otherwise, the inside/outside air introduction mode is not set to the two-layer mode but is set to a mode in which the outside air is introduced into the both air passages. In this way, it is possible to prevent the difference between the temperatures of the air blown out from a defroster opening portion and a foot opening portion from being increased due to the temperature of the outside air.

Air conditioner for vehicle

A semiconductor device including a semiconductor substrate having a main surface. An insulating film is formed on the main surface of the semiconductor substrate. A semiconductor layer is placed on the insulating film. Side insulating regions extending from a surface of the semiconductor layer to the insulating film divide the semiconductor layer into element regions. The element regions are isolated from each other by the side insulating regions and the insulating film. The semiconductor substrate has a resistivity of 1.5 .OMEGA.cm or lower. A voltage at the semiconductor substrate is set to a given voltage.

An air conditioning apparatus for an electric car capable of preventing condensation from forming on windshields, while decreasing electric power consumption. A duct forms therein a first passageway connecting an inside air inlet 8 with a lower outlet (foot outlet) 10 for discharging an air flow toward a lower part of a passenger in a cabin, and a second passageway for connecting an outside air inlet 11 with a defroster outlet 12 for discharging an air flow toward an inside surface of a windshield. A heat exchanger(s) is (are) arranged in the duct to make contact with the flow of air in the first and second passageways so as to heat the flows of air therein. The inside air after being heated by the heat exchanger is discharged from the lower outlet 10 to the cabin, while the outside air after heating is discharged from the defroster outlet 12 toward the windshield.
