摘要:
A system for reducing the transmission of vibration from a first vibrating body to a second body, the system having a first part connected to the first vibrating body, a second part connected to the second body and an electro-hydrostatic actuator connected to the first and second parts, the electro-hydrostatic actuator being operable to continuously oscillate the first and second parts 10 relative to each other at a frequency substantially corresponding to the frequency of vibration of the first vibrating body.

A particle-capturing device. The particle-capturing device includes a component having a surface that is configured to be disposed inside an enclosure, and is configured to make contact with an air-stream carrying particles within the enclosure. The component includes an electrostatic particle-capturing portion that includes a dielectric electrically insulating portion, and a plurality of charged portions. The charged portions are embedded in the dielectric electrically insulating portion, and are configured to generate an electrostatic field coupled with the surface that captures the particles from a flow of the air-stream and confines the particles at the surface. In addition, the component is configured to provide at least one additional function within the enclosure exclusive of capturing particles.

The invention provides a wafer boat for housing a semiconductor or a solar wafer that includes at least one wafer support member containing at least one slot capable of receiving at least a portion of a peripheral edge of a wafer, wherein in the wafer support member comprises silicon carbide; and at least one structural member for conveying the wafer boat into and out of a processing device connected to the wafer support member , wherein the structural member is comprised of a ceramic material that is not silicon carbide. Also included are methods of manufacturing a wafer boat having increased durability and/or chip resistance.
摘要:
A method for assembling seatbelt webbing with a sill-end bracket using an apparatus for feeding seatbelt webbing through a sill-end bracket has a form-feeding member with a tapered channel for receiving one end of a length of seatbelt webbing on an assembly line. A webbing pull-through member is fed through the sill-end bracket and engages one end of the webbing. The pull-through device is then drawn back through the sill-end bracket thus drawing the webbing through the tapered channel of the form feeding member.
