Abstract: A memory cell for an associative storage memory device includes a transmission gate which is rendered conductive or non-conductive in response to a potential on a word line for transferring information between an information hold circuit and a bit line or between the information hold circuit and an inverted bit line. Match line are precharged to ground and supply potentials, respectively, and, thereafter, a retrieval circuit compares information on the bit line or inverted bit line with information held in the information hold circuit and produces a control signal to control the potentials on the match lines in accordance with the result of comparison. After the match lines are precharged, a gating circuit is rendered conductive in response to potentials on output control line and inverted output control line to thereby couple the control signal to the match lines.

Abstract: A metallic implant base is coated with two bioactive ceramic layers. An inner bioactive ceramic layer is coated on the implant base. An outer bioactive ceramic layer is coated on the inner bioactive ceramic layer. The inner bioactive layer is vitrified at a ratio of not less than 50 volume percent, thereby improving the bonding of the inner bioactive layer to the metallic implant base and preventing migration of the metal ions from the metallic implant base. The outer bioactive ceramic layer is vitrified to a ratio of substantially less than 50 volume percent, thereby providing a desired porosity.

Abstract: A device for printing an image onto a surface, such as food containers, employs a laser that is scanned across a surface to produce a latent image on a charged photosensitive surface formed on the surface. The surface is moved relative to the laser source while the laser is activated and deactivated according to a pattern of signal pulses from a control circuit. The device thus forms a raster image. To form very fine images, the control circuit must produce pulses with very small steps in duration. The control circuit of the present invention divides a digital value representing a duration of firing of the laser into high and low order bit sequences. The high order bits, representing a value M, are applied to a counter that generates a first pulse M clock cycles long. The low order bits and the first pulse are applied to a delay circuit. The delay circuit generates a delayed version of the first pulse, which is delayed by an amount represented by the low order bits.

Abstract: A camera with a data imprinting device has a plurality of in-line LEDs producing light focused by an optical system upon a photographic film at a first and a second position, corresponding to a full size format and a panorama size format, respectively. The focused light imprints data images upon the film at the first position are larger than data images imprinted at the second position. The optical system has first and second prisms, with integrated lenses, for reflecting and focusing the light upon the film at the first and second positions, respectively. A shutter plate is selectively positioned over apertures through which the light is focused, thus blocking the light and allowing only a selected imprint to be made upon the film. A vertical pattern of the data image is created by a controller selectively illuminating the in-line LEDs while a horizontal pattern is produced by the controller illuminating the LEDs in coordination with the movement of the film past the apertures.

Abstract: Memory cells having a stable write operation are formed in an array on a CMOS gate array semiconductor substrate.

The inputs of the first and second access gates are connected to bit lines through which complementary data signals are applied. The gates of the first and second access gate transistors are connected to a write word line.

Abstract: A resistive body of a hybrid integrated circuit has a resistance pattern on a resin film. Bonding pads permit connection of current through the resistance pattern. The resistance pattern may form part of a detecting bridge for overcurrent detection. One embodiment of the invention uses a rectangular resistance pattern with an opening in the center to force current to flow on a perimeter path for minimizing maximum temperature. Another embodiment uses a serpentine resistance pattern. A face-down resistance patter reduces interference. A direct-connection bonding pad reduces the voltage generated in a parasitic capacitance to improve the resistance of the resin film to voltage breakdown.

Abstract: A conveyor belt has a textured edge for use in a spiral conveyor which includes a plurality of protrusions on the edge of the belt engaging the capstan, providing enhanced friction between the belt and the capstan. The protrusions may be placed on end links or reenforcement links, and may be a part of rods connecting links of the belt. In one of the embodiments, the capstan is textured as well to provide an additional friction. As the result, the driving force is transmitted to the belt much more efficiently, and the practical use of the plastic conveyor belt in the spiral conveyor systems is possible. In one of the embodiments, the conveyor belt is made predominantly of plastic.

Abstract: A safety screw cap indicates prior opening of a container to protect consumers from prior contamination. The screw cap has an annular band encircling its lower end which is separated from the screw cap by a perforated line. The band is affixed to a fixing clement and the fixing element attached to the container when the screw cap is screwed in place. An unattached leader portion of the band can be lifted easily to peel the band from the container. As the band is peeled from the container, it is simultaneously tom from the screw cap at the perforations. Once the band is removed, the screw cap can be unscrewed and the container unsealed. Before peeling the band away, the screw cap cannot be unscrewed without causing obvious damage to the screw cap or band. In addition, the torque required to shear-separate the band from the fixing element, the fixing element from the container or the screw cap from the band is greater than that which can be applied easily by a normal adult.
