  • Patent number: 6783299
    Abstract: A plurality of latches are employed for detachably holding a semiconductor wafer to a ring support during processing. Each latch is rotatably mounted on a post which is secured to the ring so that it can move to engage and disengage the wafer, alternately clamping and releasing it from the ring. Each latch has two opposed rollers, one to engage and disengage the wafer and the other to engage the ring. The latches should be freely rotatable into and out of engagement with the wafer. The ring usually has two pairs of opposed dimples such that each roller is in registration with each of the opposed dimples of each pair when it rotates from the engaged to the disengaged position and visa versa. The dimple in registration with the roller when engaged the wafer is sufficiently deep so that the roller does not touch the ring when clamped to the wafer.

  • Patent number: 6668694
    Abstract: An anvil blanket is molded urethane sheet material and formed with a plurality of interlocking fingers at mating opposing blanket ends and includes a depending projection which mates with a channel in the anvil about which the blanket is wrapped. A urethane insert having a hardness greater than the blanket material is molded embedded in the blanket to form a portion of the fingers and a portion of the projection depending from the fingers. A woven fiberglass fabric provides support for the blanket and which fabric is molded to the blanket. The insert has a durometer greater than that of the blanket to minimize the formation of surface recess defects at the projection which might otherwise occur due to the increased thickness of material at the projection. The insert may have other properties different than that of the blanket material including rebound, modulus, and cut and tear strength among others for resisting the formation of blanket surface defects.

  • Patent number: 6565065
    Abstract: An adaptor is for a rising disc valve which has a handle for rotating a stem in a housing bore having a shoulder and which displaces a disc valve member which seals against a frusto-conical housing seat spaced from the shoulder. A stack of Belleville -steel springs is between the disc member and the ring seal. An interface ring is between the springs and the ring seal. As the disc member is seated in its valve seat, a ring at the attachment member abuts the shoulder. The attachment member can no longer axially displace and compressively loads the springs as the disc member is further axially displaced to the valve closed state. The compressive load on the ring seal expands the seal radially outwardly against the housing bore and radially inwardly against the piston shank.

  • Patent number: 6494508
    Abstract: A filament seal for use with stranded or solid metal or thermoplastic filaments comprises a segmented housing defining a chamber in which a locking insert element is positioned, the insert comprising a thin circular disk of hardened stainless steel with a plurality of radially inwardly extending resilient cantilevered fingers each terminating with a tapered sharp pointed tip in abutting or closely space relationship defining a space substantially smaller than the diameter of the filament. The inserted filament bends the fingers and is softer than the insert, the tips digging into the filament during use. When the filament is withdrawn, the finger tips dig further into the filament severing it. If the filament is rotated in an attempt to thread the filament out of the insert, the insert rotates with the filament due to the digging action of the tips into the filament, precluding filament withdrawal from the insert.
