Abstract: A marking assembly includes a substrate and a marking device. The substrate includes a first portion made from a first material including a plurality of alignment features, and a second portion made from a second material affixed to the first portion of the substrate. The marking device is affixed to the second portion of the substrate and aligned to the alignment features of the first portion of the substrate.

Abstract: The present invention relates to a fluid ejection assembly that includes an injection-molded mounting substrate that is formed by a two-shot injection molding process, wherein a housing portion of the mounting substrate is formed by a first shot molding, and a die-attach portion of the mounting substrate is formed within the housing portion by a second shot molding. The die-attach portion is made of a material having a low coefficient of thermal expansion along a direction that is parallel to a fluid passageway in the die attach portion.

Abstract: An improved hot tip (40) for forming a thermoplastic body having a mold cavity (42) and a gate portion (44) has an elongated body member (46) and a channel (48) passing axially through the body member (46). The channel (48) has an inlet end (51) and outlet end (52) for passing a molten material, such as an amorphous resin, therethrough. The body member (46) has a necked-down portion (54) surrounding the outlet end (52) of the channel (48). The necked down portion (54) is configured to permit the outlet end (52) of the channel (48) to proximately contact the gate portion (44) of the mold cavity (42) resulting in a formed body having vestigeless gate.

Abstract: An optical disk assembly includes a web assembly having a flexible disk-shaped support web carrying a record layer. The support web has an information storage region. A pair of annular retaining ring members engage opposite sides of an annular peripheral region of the web assembly to clamp the support therebetween are formed from malleable stock material which is deformed during assembly of the optical disk assembly to provide a locking interfit therebetween with the peripheral region of the web assembly interleaved between the ring members. The peripheral region of the support is wrapped about an annular reference surface of one ring member and is pushed into an annular recess with undercut area in that ring member. The other ring member is deformed into the recess undercut.
