Patent CA-1312672-C (CA)
Title: Electron beam memory system with ultra-compact, high current density electron gun
Inventor: CREWE ALBERT V
IPC: G11B9/10
Filed: 1987-08-10
Granted: 1993-01-12
Abstract: Abstract of the Disclosure A rapid random accessed electron beam memory system comprises a disc mounted for rotation and supporting an information storage medium.  An electron gun is mounted for movement across the disc. The gun has ultra-compactness and extremely low mass, yet is capable of developing a finely focused electron beam probe at high beam current densities. The gun comprises a low-mass field emission cathode, the cathode having an emitting tip and being adapted to receive a predetermined electrical potential to form a high brightness electron source at the tip. An electrostatic focus lens forms a real image of the electron source in the vicinity of the storage medium.  The lens comprises a first electrode adapted to receive a predetermined second electrical potential which is positive relative to the potential on the tip and has a value effective to extract electrons from the tip.  The electrode defines a relatively small aperture for deforming the diameter of an electron beam which is formed.  A second electrode located downbeam of the first electrode is adapted to receive an adjustable third, focusing, electrical potential which is negative relative to the second electrical potential, and said second electrode having an aperture which is larger than the first electrode aperture.  A third electrode located downbeam of the second electrode is adapted to receive a fourth, accelerating, electrical potential which is positive relative to the third potential for accelerating the beam, the third electrode having an aperture which is also larger than said first electrode aperture.  The second, third and fourth electrical potentials are selected to establish beam-focusing fields between said first and second and between said second and said third electrodes.  The gun has an ultra-low mass in order to make feasible rapid random accessing of any area of the storage medium.

Abstract: Abstract of the Disclosure MULTIPLE I/O BUS VIRTUAL BROADCAST OF      PROGRAMMED I/O INSTRUCTIONS A method for performing an input/output process containing a programmed input/output (PIO) instruction in a multiprocessor system including at least two processors each having an associated I/O bus with I/O devices connected thereto.  The method comprises the steps of storing a unique address and a bus location for each I/O device in a device location table, determining the address of a referenced I/O device prior to performing the PIO instruction, reading the corresponding I/O bus location of the referenced I/O device from the device location table and executing the input/output process on the prescribed processor associated with the I/O bus to which the referenced I/O device is located.  The method is used in conjunction with a task scheduler including a process control block for each scheduled process.  When the PIO instruction references a device on the local I/O bus, the input/output process is executed normally.  To execute the input/output process on a remote processor, a locked descriptor identifying the remote processor is placed in the process control block for that process.  The input/output process 18 then scheduled for execution on the remote processor.

Abstract: ABSTRACT         An analog integrated circuit is disclosed using integrated field effect transistor technology comprising a plurality of sampling and storage cells.  A two-stage sampling cell design is used.  The first stage incorporates a very small capacitor coupled to the input signal through a high speed gate.          This gate, which is opened only by the simultaneous occurrence of row and column cells in the circuit, causes this first capacitor to capture at very high speed a sample of the analog signal under study.  When all the first capture sections of the cell have captured on their capacitors a sample of the analog signal, a transfer gate is briefly opened to transfer the captured and buffered sample values to the second or storage section of the cells.  This storage section incorporates a capacitor substantially larger than the capacitor in the capture section, and capable of storing the signal for a considerably longer time.

Abstract: ABSTRACT OF THE DISCLOSURE       In an integrated system to achieve a number of operations on a footwear upper assembly, an automatic rougher that includes a roughing tool adapted to remove material --and hence rough -- the cement margin (or bonding surface) of the footwear upper assembly to provide a cementing surface onto which an outer sole is later applied.  The cement margin (or bonding surface),as is known in this art, typically follows a closed-loop path that rapidly changes in all directions of an X-Y-Z coordinate system and the roughing tool must be continuously re-oriented to the many direction changes of the cement margin in order to track the margin.  According to the present teaching the upper assembly, and hence the cement margin thereof, is ordinarily moved in rotational movement, rocking movement, transverse translational movement, and, also, vertical translational movement (i.e., movement toward and away from the roughing tool) during the course of roughing. According to the present teaching, real-time data is assembled which may be used to achieve a later operation: e.g., the path of the cement margin is digitized and that digitized information is used to guide a cementer to apply adhesive unto the cement margin to adhere an outer sole to the upper assembly.
