Title: An improved cathode ray tube apparatus with reduced beam spot size
Inventor: CHANG KERN K N
IPC: H01J29/72
Filed: 1993-07-22
Abstract: There is disclosed a cathode-ray tube which employs an electron gun assembly of the laminar flow (LF) type (20, 21, 22). The beam ema-nating from the LF electron gun assembly is directed through a three-electrode einzel lens assembly (30, 31, 32) where the center electrode of the einzel lens assembly is subjected to a modulation voltage. Posi-tioned after the einzel lens assembly are magnetic deflection circuits which include a horizontal (41) and vertical (42) coil enabling the beam to deflect in the horizontal and vertical directions and which circuits are positioned internally within the CRT. A convergence assembly is also built within the neck of the CRT. Thus, the CRT provides the ad-vantages of the laminar flow gun while enabling modulation of the electron beam to provide an extremely small spot size to enable the CRT to operate with small spot size and to provide more efficient def-lection at higher modulation rates.

Title: Apparatus and method for a relocatable file format
Inventor: EIDT ERIK L
IPC: G06F9/445
Filed: 1994-03-17
Abstract: Relocation table entries in an executable object code file are interpreted as relocation instructions rather than as individual spec-ifications for a particular respective relocatable information item. An abstract machine is provided for interpreting the relocation in-structions and performing various relocation operations and various control functions for the abstract machine, in response to the reloca-tion instructions.  The abstract machine maintains certain variables containing information which is referenced and updated in response to certain types of the relocation instructions, thereby obviating the need to include such information as part of each relocation instruc-tion. Certain of the relocation instruction types can also specify a particular relocation operation to be performed on a run of n con-secutive reloactable information items, where n is specified as part of the relocation instruction.  Certain of these relocation instruc-tion types also consider each information item as including two or more individual relocations of the same or different types to per-form, thus effectively specifying a run of n repetitions of n pattern of relocations. Other types of relocation instructions are also made available. The file also contains a hashed symbol export table and pattern-initialized data expansion instructions.

Title: Seed counting apparatus for a planter monitor
Inventor: DRAGNE RASVAN N
IPC: A01C7/10
Filed: 1995-09-22
Abstract: A seed counter for counting seeds flowing through a duct includes a light transmitter on one side of the duct and light receiver on the opposed side of the duct together with an electronic circuit effecting analysis of the signals received by the receiver to generate a seed count value which represents accurately as possible the number of seeds passing through the duct. The transmitter and receiver each comprise a channel-shaped body with diodes at a base of the channel with the channel filled with a translucent potting material facing into the duct. The circuit receives the signals which include for each passage of a seed or a clump of seeds a temporary reduction in light intensity which is converted to a reduction in voltage.  Prior to start up the steady state voltage is measured and the current to the transmitter varied to provide a predetermined level of signal at the receiver.  The circuit includes a DC compression circuit and a AC compression circuit at an amplifier so as to provide an output signal in a required amplitude range. An auto-biasing section maintains a steady state signal at a required level. The amplitude of the signal is compared to a threshold by generating a first signal which is offset by the threshold and a second signal which is delayed by a predetermined time period, the comparison generating a square wave output when one of the signals crosses the other signal. The seed counter is used in a monitoring system having a central monitor which can be operated to vary the parameters of the comparison circuit including the time delay. The use of the comparison circuit assists in determining the difference between a single seed and a clump of seeds passing the transmitter/receiver simultaneously.

Title: Adjustable tie rod assembly
Inventor: MATTILA BRIAN ALLEN
IPC: B62D17/00
Filed: 1996-02-15
Abstract: An automotive vehicle has a parallelogram type steering linkage that includes two adjustable tie rod assemblies.  Each adjustable tie rod assembly comprises a tie rod and a right angled ball joint at each end of the tie rod for connecting the tie rod assembly in the steering linkage system.  The tie rod has a threaded end that is screwed into an internally threaded portion of the housing of the ball joint at the outboard end of the tie rod.  The threaded end of the tie rod carries a jam nut that is tightened against the housing to maintain the depth of the threaded end of the tie rod in the internally threaded portion of the housing.  The inboard end  of  the  tie  rod  has  a  cylindrical  head.    The cylindrical head is rotatably fit and axially captured in a cylindrical bore of the housing of the ball joint at the inboard end of the tie rod.  The tie rod has a median section of hexagonal shape for rotating the tie rod.  The length of the tie rod assembly can be adjusted while it is connected in the steering linkage system to adjust wheel toe because the tie rod can be rotated with respect to the ball joints when the jam nut is loosened.          The adjustable tie rod assembly uses low friction, lash free ball joints and can be automatically adjusted by machine easily because it has a single jam nut.
