Title: Method of making an article comprising a heteroepitaxial structure, and article produced thereby
Inventor: DYNES ROBERT C
IPC: H01L21/20
Filed: 1987-11-24
Granted: 1994-10-25
Abstract: METHOD OF MAKING AN ARTICLE COMPRISING A HETEROEPITAXIAL STRUCTURE, AND ARTICLE PRODUCED THEREBY            Abstract Disclosed is a technique, formed "mesotaxy", for producing a heteroepitaxial structure comprising a layer of single crystal second material embedded in, and epitaxial with, a single crystal first material matrix. Mesotaxy comprises implantation of at least one chemical species (e.g., Co, Ni, Cr, Y or Mg) into a single crystal body (typically a semiconductor, e.g., Si or Ge) such that a buried layer rich in the implanted species is formed, and heat treating the implanted body such that a buried stoichiometric compound layer (e.g., CoSi2) isformed. Exemplarily, 3 ? 1017/cm2 200 keV Co ions are implanted into (100) Si nominally at 350°C, followed by a heat treatment that consists of 1 hour at 600°C and 30 minutes at 1000°C. The resulting buried CoSi2 layer is epitaxial with the Si matrix, has high conductivity and is of good crystalline quality. The Si overlayer is of device quality. The thus produced heteroepitaxial structure can then be used to produce semiconductor devices, e.g., MOSFETs with a buried ground plane.

Abstract: ABSTRACT OF THE DISCLOSURE     A CPU with an interface to two different RAMs which operate at different rates.  The interface circuit includes a decoder which examines the addresses from the CPU and determines whether a faster cycle or slower cycle is needed.  The slow RAM provides video signals to a video display.  The fast RAM includes an image of the video signals stored in the first RAM. When the video signals are read by the CPU, they are read only from the fast RAM, however, when it is necessary to update the video signals, they are written into both the slow and fast RAMs.

Title: Method and apparatus for controlling the growth of cartilage
Inventor: LIBOFF ABRAHAM R
IPC: A61N2/04
Filed: 1989-09-27
Granted: 1994-12-20
Abstract: An apparatus and method for regulating the growth of cartilage in vivo are provided. The apparatus includes a magnetic field generator and a magnetic field detector for producing a controlled, fluctuating, directionally oriented magnetic field parallel to a predetermined axis projecting through the target tissue. The field detector samples the magnetic flux density along the predetermined axis and provides a signal to a microprocessor which determines the average value of the flux density. The applied magnetic field is oscillated at predetermined frequencies to maintain a preselected ratio of frequency to average flux density. This ratio is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field as the composite magnetic flux density changes in response to changes in the local magnetic field to which the target tissue is subjected. By maintaining these precise predetermined ratios of frequency to average magnetic flux density, growth characteristics of the target cartilage are controlled.

Abstract: A radially acting track follower system is provided with an optical scanner pickup for an audio or video record playback apparatus. The system generates three light spots disposed on a line with a movable phase grating (diffraction grating) and the three spots can be adjusted relative to the tangent at the track pickup scanning location. The middle or main light spot serves to provide scanning of the track signal information. The two outer or auxiliary light spots serve to provide readjustment. They are displaced radially oppositely to each other by equal amounts and are disposed at equal distances from the middle spot. The light intensity of the outer spots is picked up by detectors and processed into control signals. These are used as a drive for the phase grating, which can be controlled around its center point and the rotation axis of the phase grating coincides with the light beam, which can be provided by a semiconductor laser. The drive can operate electrodynamically or can be provided by a piezoelectrical torsion converter. The control signal can have for example 10 kilohertz and is superposed to the control signal for the drive and it improves the sensing and following properties of the system without the disadvantage of the superposition of the scanned information signal with the control signal.
