Title: Vector processor using buffer for preparing vector data
Inventor: HAYASHI HIDEO
IPC: G06F15/78
Filed: 1989-10-10
Granted: 1994-05-31
Abstract: ABSTRACT OF THE DISCLOSURE   In a vector processor, a decoder generates a load request signal if an instruction stored in an instruction register is a vector load instruction and causes the instruction to be transferred to a stack. A resource manager has a plurality of flags associated respectively with vector registers provided in a calculation circuit and constantly updates the flags in accordance with contents of the associated vector registers. A contention detector is responsive to a vector load instruction being loaded into the stack for generating a proceed-to-transfer signal if no contention is detected between the vector load instruction and a corresponding flag in the resource manager. A buffer is provided in a memory controller for storing vector data from the memory in response to the load request signal from the decoder and transferring it to the calculation circuit in response to the proceed-to-transfer signal from the contention detector.

Title: Snowmobile suspension
Inventor: BOURRET MICHEL
IPC: B62D55/108
Filed: 1990-01-17
Granted: 1997-11-11
Abstract: In a snowmobile track suspension the slide frame that contacts the ground-engaging run of the track belt is carried on front and rear suspension arm assemblies.  The front suspension arm assembly is pivoted to the vehicle on the axis of the sprocket drive shaft.  The rear suspension arm assembly is articulated, having upper and lower sections that are rearwardly angled and pivotally interconnected and support in the region of the pivotal interconnection the idler wheel that maintains the track under tension.  The arrangement eliminates stretching of the track and lengthens the track life.  Furthermore the rearwardly angled arrangement of the rear suspension arm assembly allows easier backward motion of the snowmobile because the lower arm section provides an angle of attack to help the track rise above an obstacle.

Title: Polygon scanner with predictable facet deformation characteristics
Inventor: NOWAK WILLIAM J
IPC: G02B26/12
Filed: 1991-03-08
Granted: 1995-11-28
Abstract: Polygon scanners of the type used in ROS printers, are subject to centrifugal caused distortion at the mirror (facet) surface at certain rotational speeds. This distortion can affect the performance of the scanning beam at an image plane. Techniques are provided for predicting the radial facet dlstortion at expected rotational speeds, and for specific polygon designs. In one embodiment, the surfaces of the polygon facets are modified to incorporate the reverse of the radial distortion curve which is predicted at the rotational load. When operating at the rotational load, the facet surface then deforms to a desired planar (flat) configuration. In another embodiment, the polygon element structure is modified by adjusting the polygon modules of elasticity, weight density, and the polygon continuum to achieve a distorted facet surface at rotational speed which provides the functions normally provided by a post polygon lens.

Title: Sampler safety interlock device
Inventor: HUNSZINGER PETER A
IPC: G01N1/10
Filed: 1991-07-03
Granted: 1998-12-29
Abstract: A flow sampler device which can be employed in a catalytic reactor system comprises a sample receiver, and an inlet and outlet valve which are each in fluid communication with the receiver.  Each of the valves includes  a valve stem which  is  rotatable about a longitudinal  axis  thereof  so  as  to  actuate  the respective valve and has a collar element secured thereto.   This collar element has a first end and a second end and comprises a wall means which defines a longitudinal  passageway  therethrough.    The  collar element also includes a locking slot which is defined therein and which includes a first portion extending from the first end of the element and a second portion which  is  substantially perpendicular  to  the  first portion.  In a preferred embodiment, the collar element is cylindrical and the locking slot is substantially L-shaped.   The collar element effectively prevents a wrench which operates the valve from being removed from the valve stem when the valve is in a open position. Thus, because only one valve is open at any one time, the reactor is not allowed to vent through the sampling device.

Title: Equalizer for optically transmitted information signals
Inventor: KRIMMEL HEINZ
IPC: H04B10/2513
Filed: 1992-06-26
Granted: 1998-04-14
Abstract: To compensate for nonlinear distortions in analog optical communication transmission systems, caused by laser chirps and the chromatic dispersion of the optical fiber, an equalizer in the form of an LC component is known, whose capacitance is formed by a variable capacitance diode.  If this equalizer is to be adjusted for considerable signal distortions along transmission path length), it must operate at great capacitance, which reduces its bandwidth.  In order to be able to equalize large bandwidth signals (e.g. 600 MHz) containing considerable distortions, the invention indicates an LC chain circuit with LC components of the known type, as the equalizer.      Further developments of this solution concern the appropriate polarizing of the variable capacitance diode and maintaining the frequency response constant, when adjusting the equalization.

Abstract: A gaming apparatus with bi-directional, rotatable symbol bearing reels is disclosed.   The gaming apparatus includes a microprocessor which generates a direction signal to control the rotation of each of the reels via a reel control mechanism.   The reel  control mechanism employs stepper motors or the like to rotate each of the reels in either a clockwise or counterclockwise direction about an axis, depending on value of the direction signal.  In some cases, the microprocessor generates the direction signal in accordance with a random event so that the reels rotate randomly in different directions.
