Abstract: A method of manufacturing a thick walled Moineau-style stator entails drawing a thick walled tube through rotatable internal and external dies to form a helical outer profile including crests and through on the tube. The tube initially has one end with a diameter smaller than the others, with the smaller diameter end being inserted between the inner and outer dies, where it is seized and drawn through the dies.

Abstract: In the particular embodiments described in the specification, bearing material is applied to the bearing surface of a connecting rod eye by thermal spraying of the bearing material such as by plasma coating. In a particular embodiment the large connecting rod eye is plasma-coated with an aluminum bronze. After the plasma coating, the connecting rod eye is opened by removing the bearing cover from the rest of the connecting rod, thereby breaking the plasma layer. Subsequently, the cover is screwed on again, and the surface of the bearing layer is finished by fine spindling. The method results in reduced assembly costs.

Abstract: A method for using a moisture-protective container to protect an integrated circuit is disclosed herein. The integrated circuit is placed into a container having a first surface and a second surface that is opposite the first surface, and then the container is closed with a seal. Next, the seal is broken to remove the integrated circuit for evaluation. After evaluation without subjecting the integrated circuit to burn-in, the integrated circuit is restored to the container and the container is resealed with the seal. Lastly, the seal of the container is broken to connect the integrated circuit to a substrate without elevating the temperature surrounding the integrated circuit above the temperature at which evaluation occurred.

Abstract: A method for manufacturing a metal carrier usable for an exhaust gas purifying catalyst, by spirally winding a blank material into the form of metal carrier. In the method according to the invention, two to four sheets of flat metal foils are provided, having projections and holes over entire surfaces thereof, as the metal carrier blank material. The flat metal foils are spirally wound under a mutually overlapped state, into a form of cylindrical body, and the tip ends of the projections are joined to corresponding surfaces of the flat metal foils.

Abstract: The end faces of the edge portions of a flat plate, which have been respectively cut into a given shape according to a trimming operation, are then respectively face-struck into a linear shape. Also, in the trimming operation, each of the edge portions of the flat plate is cut into a shape having a larger dimension than that of a finally required shape thereof, and the thus produced excess length portions of the edge portions are worked by compressing when a pair of semidivided cylindrical portions are butted against each other. Since a connecting portion situated between the pair of semidivided cylindrical portions is always pressed with a given pressure, the working properties of the connecting portion in the molding operation are prevented from being revived.
