In an air conditioner for a vehicle, a flow speed of air flowing through a first ventilation part of an evaporator is faster than a flow speed of air flowing through a second ventilation part of the evaporator when an intensive air-conditioning operation for a driver seat is operated, with respect to a case where a normal air-conditioning operation is performed. In this case, a correct target evaporator temperature is calculated to be higher by a predetermined temperature than a target evaporator temperature, and a detected temperature detected by an evaporator sensor is approached to the correct target evaporator temperature. Therefore, it can restrict the second ventilation part from being frosted.

A movable member 13, whose physical change occurs corresponding to a respiration flow rate, is disposed in the pipe 11. The pipe 11 and holder section are structured to be capable of being detachable. When staring respiration with the mouth touching pipe 11, the movable member 13 bends corresponding to respiration flow rate. Image data of the movable member 13 is obtained through the pipe 11 by a CCD area sensor disposed outside the pipe 11 and the bending amount is detected. The respiration rate is calculated based on the flow rate data corresponding to the bending amount of the movable member 13 in use.

An air separation method and apparatus in which a supercritical oxygen product is produced by heating a pumped liquid oxygen stream having a supercritical pressure, through indirect heat exchange with a boosted pressure air stream. The indirect heat exchange is conducted within a heat exchanger and a liquid nitrogen stream is vaporized in the heat exchanger to depress the pressure that would otherwise be required of the boosted pressure air stream to heat the pumped liquid oxygen stream. The pumped liquid oxygen stream constitutes 90 percent of the oxygen-rich liquid removed from an air separation unit in which the air is rectified, the liquid nitrogen constitutes at least 90 percent of the liquid nitrogen that is not used as reflux and a flow-rate ratio between the liquid nitrogen stream and the oxygen-rich liquid is between about 0.3 and 0.90.

The path of the at least one holding device comprises a plurality of vertical sections (34) which are horizontally offset from one another. Each vertical section (34) comprises at least two identically orientated printheads (32) arranged such that they are vertically displaced from one another, with one directly above the others. The at least one holding device moves the object (31) between the at least two printheads (32) such that part or all of its path between the printheads is vertical.

An injector for delivering a working fluid into a working environment is disclosed. According to one embodiment of the present invention, the injector includes a pre-metering chamber and a swirl chamber. A high velocity partially atomized flow is produced in the pre-metering chamber through a first exit nozzle after impinging on an atomization element, and then a swirling flow is created in the swirl chamber with the atomization element. When the swirling flow is released through a second exit nozzle, atomization can be achieved at low injector pressure with centrifugal force and shearing of the working fluid. In another embodiment, the injector includes a swirl chamber and an atomization element with a bore, through which a control valve is positioned. The control valve forces a working fluid flow through the atomization element when the injector is energized to create a swirling flow. No flow-back is required for the injectors.
