Abstract: A one-device shared trench memory cell, in which the polysilicon (22,24) and dielectric layers (26,26A) within the trench (20) extend above the surface of the trench to form a mandrel structure. A layer of polysilicon is conformably deposited on the mandrel structure. Dopant ions are diffused from the doped polysilicon within the trench to the conformal polysilicon layer, and from the conformal polysilicon layer to a portion of the substrate disposed thereunder (36). The conformal polysilicon is etched in a solvent that preferentially attacks undoped polysilicon, to provide a bridge contact (30) that is self-aligned to the polysilicon within the trench and to the diffusion region. A plurality of FETs formed on either side of the trench, by use of a sidewall-defined gate electrode (34) to maximize density. The cell produces a "poly-to-poly" and "poly-to-substrate" storage capacitor combination that maximizes charge storage capability.

Abstract: Figure 1 shows the infrared light object alarm described. 1 represents any signal generator. An infrared light source 3 is controlled by this signal via lead 2. As a result 3 radiates infrared light, which is modulated in one way or another by the said signal from 3. When infrared light is radiated it is reflected from all objects with a fairly definite shape such as object 5. The infrared light from 3 is incident as a light beam 4 on object 5, is reflected and is then incident as a light beam 6 on the input of the infrared light receiver 7. In the invention, not a single beam of light but a threedimensional bundle of rays of any angle is radiated from 3. Thus the room concerned is filled as far as possible with the infrared light radiated from 3. The receiver 7, in Figure 1, receives the total infrared light reflection of the objects which reflect the infrared light in the room concerned back to the receiver 7. At the output of the demodulator 8, an electric signal will be produced, the level of which will be a measure of the total received, reflected, demodulated infrared light emitted from 3 into a particular room. With a level detector after the demodulator 8 in Figure 1, it is possible to distinguish between a situation in which the active infrared light object alarm triggers and one in which it should not trigger. This means that the active infrared light object alarm can be set for every situation in a room for which it is not required to trigger. If then an object is introduced into the room in question, the total reflected, demodulated infrared light increases in intensity at the infrared light receiver 7. This means that, at the output of the demodulator 8, in Figure 1, there will be a larger signal, the amplitude of which is proportional to the intensity of the demodulated light entering the infrared light receiver stage 7. The level detector 9 can be adjusted so that an electrical signal change occurs at 10. This means that one or more objects are present in the room in which 3 is radiating the infrared light, thus causing an electrical signal change at 10. The circuit works always in such a way that the output signal of the demodulator 8 provides a measure of the total demodulated reflected infrared light received from the room in question at 7. <IMAGE>

Abstract: A clock control system for a multiple channel electric power system includes a master clock circuit (28) and control circuitry (40) in each parallel connected channel. The channel control circuits are initially phase-locked to a master clock signal. If the master clock signal is out of a preselected frequency range, the indi­vidual channel control circuits (38, 40) are decoupled from the master clock signal and one of those circuits produces a backup clock signal. The control circuits in the remain­ing channels are then phase-locked with the backup clock signal to provide continued parallel system operation.

Abstract: In customary processes for the continuous manufacture of a length of fibrous insulating material, made in particular of mineral fibres, a primary web which comes from a collecting chamber and has been impregnated with binders and impregnants is compacted and passed into an oven for curing the binders and impregnants. 
<??>To devise a process which with a minimum of complication makes possible a systematic arrangement of fibres having particular surface properties or of properties of the fibrous insulating material within said material, it is proposed that upstream of the curing oven the primary web be divided into two or more subsidiary webs, one subsidiary be lifted off, strongly compressed with alignment of fibres and then be brought back together with the other subsidiary web(s) and all the webs together then be cured in the curing oven.

Abstract: The invention relates to a circuit arrangement for an electronic dial pulsing switch in a subscriber station, where this dial pulsing switch is formed by a longitudinal transistor located with its emitter-collector path in one wire of the subscriber loop, which transistor is controlled at its base via a current path for its base current to the other wire of the subscriber line in order to form the dial pulses. The object of the invention is to implement this current path for different current strengths on the line always with sufficiently low impedance but free from unnecessary attenuation due to high insertion loss. This is achieved by forming the current path as a current control dependent on the strength of the current on the line. It can be applied essentially in all microprocessor-controlled subscriber stations. <IMAGE>

Abstract: A single processor in a disk file digital servo control system generates a head actuator control signal at two different rates, depending on whether the read/write head is being moved between data tracks or is following a specific track. A sampling clock generator (65) receives servo timing information from a recorded servo disk surface (22) and generates interrupt signals to the processor at pre­determined frequencies selected by the time required for the processor to run the algorithm which generates the control signals. Upon receipt of a seek command to move the head to a target track, or a predetermined head position error signal indicative of arrival of the head to the target track, the microprocessor enables or disables appropriate inter­rupts so as to select one of the appropriate rates for generating the control signals. The digital servo control system thus allows servo position information to be sampled at a higher frequency during track following.

Abstract: A transmitter circuit (10) for transmitting a digital data signal over a bus line (14) in a digital data processing system includes a MOSFET bus driver transistor (11) having a gate to drain capacitance (C GD ) which substantially dominates other capacitances at the gate terminal. The bus driver transistor (11) is driven by a buffer circuit (12) having pull-up and pull-down transistors (16, 17), the current through which is controlled by current sources (20, 21). The gate terminal of the driver transistor (11) is connected to, and controlled by, the node (22) between the pull-up and pull-down transistors (16, 17). The drain terminal of the driver transistor (11) is connected to, and controls, a bus line (14). To assert a signal on the bus line (14), the pull-up transistor is turned on to drive current into the node (22) at a rate governed by the current source (20), which increases the voltage level of the node (22). When the voltage level of the node (22) reaches the driver transistor's threshold level, the driver transistor (11) begins to turn on, allowing the voltage level of the bus line (14) to drop. Contemporaneously, current flows into the node (22) from the bus line (14) through the driver transistor's high gate to drain capacitance (C GD ), thereby limiting the voltage level of the node (22), and thus the current flow through the driver transistor (11). Thus, current flows through the driver transistor (11) from the bus line (14) in a manner controlled, in part, by the voltage level on the bus line (14). In negating a signal on the bus line (14), the operations are similar, with current flowing out of the node (22) through the pull-down transistor (17) and the driver transistor's gate to drain capacitance (C GD ).
