Abstract: In a printing press of the lithographic type, a dampening system regulates the flow of dampening solution onto the oscillating roller for application to an adjacent dampener roller and then onto a plate cylinder. The dampening means includes a plurality of circumferentially grooved, longitudinally spaced discs, axially aligned and positioned adjacent to the oscillating roller. The grooved circumferences of the discs are so positioned as to be rotatable through a dampening solution source. A plurality of individually actuable means is each so positioned as to direct air under pressure at one of the grooved circumferences of the discs towards the oscillating roller. In this way dampening solution from the circumferential groove is directed into a fine spray onto the periphery of a section or zone of the oscillating roller. The system also includes means for controlling the amount of air directed from one of the air pressure means independent of every other air pressure means.

Abstract: Electronic game apparatus includes a series of lights that are rapidly and repetitively illuminated in succession to simulate a rapidly moving light. A player has under his control a switch which, when actuated, stops the apparent movement on a particular light. Different packaging schemes provide a variety of ways in which the game can be played either by one or more players. A variable frequency oscillator allows the speed at which the series is illuminated to be varied or adjusted to suit a player's skill and interest and to allow the game to be played as a game of skill or of chance. Alternate embodiments allow either one light at a time to be lit or the series can be completely turned on one at a time. Additionally, the direction in which the lights are illuminated can be either unidirectional or bidirectional. The game apparatus may also include automatic score keeping facilities.

Abstract: A multilayer ceramic, multi-chip, dual in-line packaging assembly comprises a ceramic substrate with a pair of semiconductor chip receiving cavities therein. A metalization pattern partially embedded within the substrate provides electrical paths for semiconductor chip devices joined thereto to external circuitry. Semiconductor chips are joined to exposed pads within the chip receiving cavities. Metalization spaced from and positioned beneath the semiconductor chip devices completes interconnections between semiconductor chip devices. Exposed finger areas are spaced from one another and about the semiconductor chip receiving cavities. Embedded lines extend from the finger areas to external circuitry and interconnection means extend between finger areas.

Abstract: A burning logs simulator comprises a burning logs replica illuminated internally and presenting to a front viewer or user the appearance of a pile of burning logs. Curtains of mechanically agitated flicker strips are located behind the front of the replica with a light source therebetween and produce flickering imparting a sensation of a fast burning, hot fire throughout the face of the burning logs. The noise or sounds of such a fire are simulated by the moving interaction of two pieces of material, one piece having looped fibers and the other having hooked fibers.

Abstract: A high power semiconductor device is formed by providing a semiconductor substrate of N.sup.- conductivity, rendering the backside of same porous as by subjecting same to anodic treatment carried out in a concentrated solution of hydrofluoric acid, converting the porous region to an N.sup.+ region, as by arsenic diffusion and forming an active device by conventional techniques in the top surface of the substrate. The method permits usage of high quality N.sup.- substrates and at the same time eliminates the requirement of growing thick epitaxial layers.

Abstract: A large scale integrated (LSI) chip or semiconductor device includes a memory array and associated logic circuitry. The array is "embedded" in the sense that it is not directly accessible, either in whole or in part, from the input and output terminals or pads of the device. To facilitate testing there is added to the device gating means to the memory array and wiring extending from primary access points of the device to the memory array bypassing and in parallel with the logic circuitry. The device further includes control means operatively associated with the gating means for switching the input to the array between the logic circuitry and the primary access points. In the latter condition direct access to the array is permitted, thereby facilitating testing.

Abstract: An LSI semiconductor device includes a memory array incorporating address, data and buffer registers, and associated combinatorial and/or sequential logic circuitry. The array is "embedded" in the sense that the memory array is not directly accessible, either in whole or in part, from the input and output terminals or pads of the device. To facilitate testing, means which bypass the associated logic circuitry are provided for scanning information directly into the address and data registers. The information so introduced is shifted through the register strings. The interconnections from the associated logic circuitry are inhibited during the testing mode while the information shifting means are inhibited during an operative mode. The information scanned into the registers may be scanned out to determine whether there is a defect or problem in the register strings. Output levels from the array are compared with an expected output.

Abstract: An LSI semiconductor device includes a memory array incorporating address and data registers, and associated combinatorial and or sequential logic circuitry. The array is "embedded" in the sense that the memory array is not directly accessible, either in whole or in part, from the input and output terminals or pads of the device. To facilitate testing, the address registers and data registers are converted to counters by the addition of an EXCLUSIVE OR circuit to two or more positions of the register. The address and data registers are stepped through all of their states. The data register counter outputs may then be compared with the array outputs, thereby allowing one to check address selection as well as the ability to write or read at each of the storage locations.
