Abstract: A process for repairing a hydraulic line having a damaged end section. The damaged end section is severed from the line and a male or female coupling member is formed in the new end. This is accomplished by reducing the wall thickness by increasing the inside diameter (female coupling member) or decreasing the outside diameter (male coupling member). A tubular tip is provided having a major portion the same length as the severed section and an end portion that is an extension of the major portion with a reduced wall thickness forming a male or female coupling member opposite that formed in the end of the tube. Coupling is achieved to regenerate the end section with a consistent inside and outside diameter along the tube and across the coupling intersection.

Abstract: Described is a machine for pre-gluing raw circuit surfaces of printed circuit boards (P.C. boards) at an adhesive station and properly positioning the P.C. boards at a placement station for placement of leadless electronic components (chips) onto the adhesive. A carousel provides program preselected vertical supply of taped components to a feeder assembly which feeds individual chips onto a nozzle of a turret-type vacuum head at a pick-up station. The turret-type head has four nozzles spaced 90.degree. apart about the central axis of the head. As the turret is rotated, a chip is transported by a nozzle, sequentially, from the pick-up station to a centering and testing station, a centering and orienting station, and a placement station. Located between the testing and orienting stations is a chip removal station for ejecting defective or inverted chips. Sensors are located at the adhesive and placement stations to detect defective P.C. boards so that they may be bypassed.

Abstract: A process is provided for fabricating a semiconductor structure wherein the structure has to be exposed to certain oxidizing conditions during certain of its processing steps, such as its high temperature annealing in an oxidizing ambient. It includes depositing a "sacrificial" layer, such as silicon, to provide a uniformly oxidizing surface during subsequent annealing operations. This sacrificial layer, which oxidizes uniformly, produces an oxide layer which also etches uniformly. Thus, after the annealing is completed, the surface oxide is removed through etching and the sacrificial layer is then also removed through a different etching step.
