Two memory cells each can be entirely fabricated in only two isolation beds. In one embodiment each bed contains one lateral PNP and one vertical NPN transistor in a merged structure. In a second embodiment, each bed contains one lateral PNP and two vertical NPN transistors in a merged structure. Memory access circuitry provides a high ratio of selected to unselected cell current in order to permit fast memory operation.

A method for applying a foam composition containing a coloring agent randomly dispersed therein onto a textile fabric. The coloring agent is mixed into the foam in a non-homogeneous manner and deposited onto a fabric in a system having a depositing means which is rotated and moved transverse to the direction of travel of the fabric being treated so as to achieve substantially random motion with respect to the fabric. The foam-coloring agent composition is caused to flow axially and in one embodi...

A dynamic random access memory (10) receives a memory address of a row decoder (14) which charges a selected row line (18). When the row line (18) is charged an access transistor (24) in a memory cell (22) is rendered conductive to connect a storage capacitor (26) to a bit line (30). The bit lines (30, 38) are previously set at an equilibration voltage. The voltage on the bit line (30) is driven slightly above the equilibration voltage if a high voltage state had been stored in the capacitor (26...

Apparatus for dual random number selection is provided to pick numbers in a lottery or the like. Said invention consists of a base having a mixing reservoir, a well and a conduit between the mixing reservoir and the well, a plurality of filler and winning balls contained in the mixing reservoir, a wheel with a plurality of receptacles on its circumference each randomly numbered contained in the wall, a transparent cover over the base with the wheel's shaft through it connected to a knob to allow...

A random pattern generator is used to generate waveforms displayed on a cathode ray tube. A plurality of waveforms are built up to form an observed pattern for use in the design of textiles or carpets. To form a waveform a series of numbers Xi (i=1, 2, 3 . . . ) are generated each representing an amplitude value of a waveform X. Each value of Xi is translated into a number Y in a series of numbers Z, then incremented by a changeable amount A to obtain a different value Zi which collectively are ...

A toy has a housing on which are located a plurality of individual operator buttons. These slide from a first position to a second position. The toy further includes an indicator member which moves from a nonindicating position where the indicator member is located inside of the toy to an indicating position wherein a portion of the indicator member is located outside of the toy. Movement of the indicator member from its position inside the toy to its position outside of the toy is accomplished ...

A random number selector has a compartment that accommodates balls of two contrasting colors, e.g., black and white. Overlying the compartment is a window on which are marked indicia to be selected, e.g., numbers. The indicia also are black. Certain of the numbers are masked and rendered invisible by the black balls located behind them. The numbers to be selected are highlighted by the color-contrasting white balls.

A dynamic random access memory comprises a one-transistor type MOS dynamic random access memory of an open bit line type, which comprises two memory arrays at the left and the right sides of sense amplifying circuits (2). Each of both memory arrays comprises a plurality of memory cells (1) and dummy cells (3), each of columns of memory cells (1) and dummy cells (3) having a cell plate voltage control circuit (13) connected at the end thereof through a cell plate (8). Each cell plate voltage cont...

A memory circuit in which data words are held in a continuous sequence of locations, a new data word being insertable at a selected address, and a stored data word being readable from a selected address. On data word insertion, the selected location is first vacated by shifting data already stored above or below the selected address by one location. For example, all the data in locations having addresses equal to or greater than the selected address are shifted. Data read from the circuit may be...

A portable hand held apparatus for randomly selecting by chance a plurality of numbers particularly suitable for lottery selections. A plurality of buoyant cubes are contained in the fluid tight generally opaque container. The container has a window for viewing a predetermined number of the cubes temporarily trapped and arranged adjacent the window after agitating the container by a user. A cube receiving channel is formed within the container adjacent the window for releasably trapping a desire...
