Abstract: ABSTRACT OF THE DISCLOSURE            The impurity doping apparatus is comprised of a vacuum chamber, a heater for heating a silicon substrate placed in the chamber, and a gas supply source for supplying a diborane gas containing an impurity component of boron to the chamber.  A regulating valve is disposed between the chamber and the gas supply source to regulate the gas flow rate.  A CPU is provided to control the heater and the regulating valve according to a given sequence of first, second and third procedures so as to dope the boron into the silicon substrate.  The CPU operates according to the first procedure to effect heating of the silicon substrate in the vacuum chamber to activate a surface of the silicon substrate.  The CPU operates according to the second procedure to effect charging of the diborane gas into the vacuum chamber while heating the silicon substrate to deposit a boron adsorption film on the activated surface.          The CPU operates according to the third procedure to effect annealing of the silicon substrate to diffuse the boron from the adsorption film into the bulk of the silicon substrate.

Title: Radial support system for a mr magnet
Inventor: HERD KENNETH G
IPC: H01F6/00
Filed: 1991-01-17
Abstract: RADIAL  SUPPORT  SYSTEM  FOR  A  MR              MAGNET        Abstract of the Disclosure A refrigerated superconductive magnet is provided with six magnet cartridge radial struts supporting the magnet cartridge in the vertical and lateral directions.  The struts are positioned such that two lateral struts on each end of the magnet cartridge react against the contact force of the cryocooler cold head and support half of the vertical (gravitational) load of the magnet cartridge.  Two vertical struts support the other half of the vertical load.  The vertical struts pivot to allow the cartridge axial centerline to shrink towards the cryocooler interface during cool down. The strut attachment points have been located near the horizontal midplane in order to minimize the sag of the magnet cartridge due to its own weight.

Title: Polygon sort engine
Inventor: COURTRIGHT GLENN M
IPC: G06T15/40
Filed: 1991-03-15
Abstract: A polygon sort engine (100) including first and second apparatus for sorting. The first apparatus for sorting receives planar, externally convex polygon vertices (102) from an external polygon tiling engine. This includes points and lines. The state machine (156) on the second apparatus for sorting interfaces with the polygon tiling engine and a raster engine in a graphics pipeline. It provides a control signal which determines when the first apparatus for sorting will receive the next polygon. The second sorting appartus also controls whether the polygon is stored in the PING or PONG memory (184, 186). For example, as the state machine (156) is controlling the sorting of the current polygon into the PING RAM (184), the state machine (156) will also be controlling the loading of the previous vertices and the PONG RAM (186) into the raster engine.

Abstract: The invention relates to a cutting device for a web winder.          The cutting device includes a frame construction and a cutting blade, by means of which cutting blade the web in a reel formed on support of carrier drums can be cut off before new winding is started. The cutting device preferably includes an actuator and power transfer members which are operationally connected with the cutting blade of the cutting device.  In this manner, the movement of the actuator is transferred by an intermediate of the power transfer members to the cutting blade so that the cutting blade moves along a curved path.  The cutting blade is thereby movable between a lower position and an upper position, the cutting blade in its lower position being substantially more distant from the carrier drum than in its upper position.
