Abstract: A device and method is disclosed for delivering NO to a patient. The device utilizes a single controller that controls two separate flow controllers to deliver an oxygen-containing gas and a NO-containing gas to the patient. The flow profiles of the oxygen-containing gas and the NO-containing gas are controlled by the controller. In one aspect of the invention, the flow profile of the NO-containing gas is proportional to the flow profile of the oxygen-containing gas throughout patient inspiration. In this regard, the patient receives a steady concentration of NO. In another aspect of the invention, the flow profile of the NO-containing gas is quasi-proportional to the flow profile of the oxygen-containing gas. In this regard, the NO-containing gas flow profile is altered to provide an increased concentration of NO either at the beginning or end of inspiration.

Abstract: A workpiece for a hollow rack shaft is a substantially rectangular plate. The opposite two sides of this workpiece are respectively provided with a complementary profile composed of the continuation of a convex portion and a concave portion and when the workpiece is cylindrically formed, the profiles are mutually engaged. As the width of a part the width of which is the largest in the convex portion is larger than that of a part the width of which is the smallest in the concave portion, the two sides are prevented from being detached after engagement. Further, the opposite convex portion and concave portion are mutually caulked and hereby, mutual gap is removed.
