Use of a multilayer etching mask that includes a stud mask and a removable spacer sleeve for MTJ etching to form a bottom electrode that is wider than the rest of the MTJ pillar is described. The first embodiment of the invention described includes a top electrode and a stud mask. In the second and third embodiments the stud mask is a conductive material and also serves as the top electrode. In embodiments after the stud mask is formed a spacer sleeve is formed around it to initially increase the masking width for a phase of etching. The spacer is removed for further etching, to create step structures that are progressively transferred down into the layers forming the MTJ pillar. In one embodiment the spacer sleeve is formed by net polymer deposition during an etching phase.

A restraint for retaining a person within a seat. The restraint has a lap bar and a shoulder bar which can be independently adjusted. The lap bar can be rotated either to retain a person or to permit a person to enter or exit. Also, the lap bar can be pulled farther away or pushed closer to a person. When extended completely, the lap bar will remain locked in such position until the lap bar is rotated toward the position a person will occupy. When pushed toward a person, the lap bar cannot be pushed farther away until a rod to which the lap bar is attached is released from a lock. The shoulder retainer is attached to a similar rod which is locked in this same fashion.

An oil mist separator has a pressure regulator valve which is located in the blow-by line downstream of the oil mist separator element in the flow direction of the gas. The pressure regulator valve has a bias so that it opens above a specified pressure difference between the blow-by line and a neighboring chamber. Located around the oil mist separator element is a bypass line which has a bypass valve. The bypass valve has a bias that causes the bypass valve to close below a specified pressure difference between the suction side and the pressure side of the oil mist separation element. The pressure regulator valve and the bypass valve are connected with each other so that the pressure regulator valve, as it closes, increases the bias of the bypass valve.
