Granted: 1991-04-09
Abstract: Abstract The present invention relates to a method of fabricating a device which includes an iron-doped, indium-based, compound Group III-V semiconductor region. The method is comprised of the steps of forming a precursor gas comprising a carrier gas, a volatile dopant compound, a volatile indium compound and a Group V hydride; directing the precursor gas through a heated chamber to contact a heated deposition body; and inducing deposition of the compound semiconductor on the body.  The carrier gas comprises an inert gas, the dopant  compound includes iron and the concentration of hydrogen in the precursor gas is limited to prevent excessive precipitation of iron.  The concentrations of the volatile indium compound at the body and of the Group V hydride are maintained sufficient to result in the deposition.

Title: Tilt mechanism, particularly for knee-tilt chair
Inventor: MROTZ WALTER C III
IPC: A47C3/026
Filed: 1988-02-08
Granted: 1991-05-21
Abstract: TILT MECHANISM, PARTICULARLY FOR KNEE-TILT CHAIR                 ABSTRACT OF THE DISCLOSURE    The seat and pedestal of a chair are joined by a knee-tilt mechanism which includes a first support fixed to the underside of the seat adjacent the front edge thereof, and a second support fixed to the pedestal and having a sidewardly extending support tube arrangement. The first support has bearing hubs rotatably engaged with the support tube to define a horizontal tilt axis. A restoring mechanism is disposed within the second support for exerting a restoring torque about the tilt axis for urging the seat toward its horizontal position. The restoring mechanism, in the preferred embodiment, employs a sleevelike spring member of an elastomeric material disposed on the tilt axis for developing a restoring torque which generally linearly increases as the seat tilts away from the horizontal position.  A second spring coacts between the supports for generating a second restoring torque which is additive with the first torque to effectively cause a torque dwell to facilitate tilting beyond an intermediate position.
