Title: Slot machine
IPC: A63F5/04
Filed: 1987-03-16
Abstract: A slot machine having a plurality of symbol series (3, 4, 5) disposed side by side and movable lengthwise independently, selects a combination of symbols at a winning line which is judged whether it coincides with any one of a set of predetermined winning-prize symbol combinations to pay out a predetermined number of coins. At least one of the symbol series includes a special mark (22) as distinguished from the symbols. When the slot machine selects a combination corresponding to any one of the predetermined winning-prize symbol combinations with one of its symbols replaced with the special mark, the slot machine pays out coins as a special dividend the number of which is larger than that of coins to be paid out upon the one predetermined winning-prize symbol combination.

Filed: 1989-04-14
Abstract: The present invention utilizes back lighting 
optics to produce converging white light over an 
area larger than an area of the edge of the convex 
object being profiled by the present invention. 
Opposite the back lighting optics are located a 
shadow image detector which detects the shadow image 
of the edge of the convex object, which is located 
between the back lighting optics and the shadow 
image detector. The detector generates a plurality 
of pixel outputs from each of a plurality of 
vertical locations for the shadow image of the edge. 
A rotating stage provides relative movement between 
the convex object and the detector/optics 
arrangement. The output of the detector which is a 
high resolution camera is fed into a data processing 
system which determines a sub-pixel distance 
measurement for each of the plurality of vertical 
locations and arranges the sub-pixel distance 
measurements into rows and columns to construct a 
surface profile of the convex object.

Title: High speed tape duplicating machine
IPC: G07F17/16
Filed: 1989-10-03
Abstract: A duplicate recording system uses video cassettes for 
storing master library recordings. On both the recording and the 
duplicating ends of the system, all signals are buffer stored in 
an electronic memory while the signals are in a digital form. 
This buffer storage completely isolates the recording/reproducing 
steps so that the usual parameter of restraints disappear. For 
example, the duplication ratio may be any value within the 
capabilities of the recording/reproducing machines. This 
isolation eliminates expensive setup procedures heretofore 
required to switch from one to another duplicating ratio. The 
buffer storage also provides a more precise transfer with greater 
fidelity of the recorded signals. A computer calculates a 
smoother analog curve when the digital-to-analog conversion is 
made.

Abstract: A control system for regulating AGV vehicle flow in 
an AGV system of the type wherein a plurality of AGV 
vehicles have a guidance system enabling each of the AGV 
vehicles to follow a path on a floor surface and reduce 
speed or stop. The control system comprises a passive 
closed antenna loop positioned adjacent to the path 
along a length thereof, a vehicle transmitter located on 
each vehicle for inducing an electromagnetic signal in 
the antenna loop for only so long as one of the vehicles 
is positioned on the portion of the path adjacent the 
antenna loop, and a vehicle receiver located on each 
vehicle operating in the system.  
     The receiver is positioned on the vehicle in 
spaced-apart relation to the vehicle transmitter for 
sensing the signal induced in the antenna loop and 
generating an output to the guidance system of the 
vehicle. A signal is induced in the antenna loop by a 
first vehicle is detected by the vehicle receiver of a 
second vehicle when in proximity to the antenna loop and 
the second vehicle is slowed or stopped as required to 
avoid a collision between the first and second vehicles. 
 
 
When the first vehicle no longer induces a signal in the 
antenna loop the second vehicle is permitted to continue 
along the path.
