Abstract: In a process for forming planar, dielectric filled, narrow and wide trenches in integrated circuit devices, following the formation of the trenches (2, 3) in the substrate (1), successive layers of conformal silicon nitride (15), conformal polysilicon (14), and relatively conformal CVD oxide (16) are formed to the relative depth of the trenches (2, 3). A photoresist mask (22) is then first selectively formed over the central regions of the wide trenches (3) and then used as a mask during the anisotropic etch of exposed oxide. The underlying polysilicon layer (14) serves as an oxide etchant stop, and also provides the material from which the next successive oxidation partially fills the previously etched regions with thermal silicon dioxide. A further layer of oxide is then formed by poly deposition and oxidation. The nitride layer (13) underlying the polysilicon layer prevents oxidation of the substrate. Fabrication is concluded with a planarization to the level of the active regions (8, 9, 11), including an etch of the nitride layer (13) over such active regions (8, 9, 11).

Abstract: A transmitter provides an output representative of a parameter. A generating circuit in the transmitter senses the parameter and provides charge packets having adjustable magnitudes to a measurement circuit. The measurement circuit measures the quantity of charge and provides a measurement signal representing the charge to a feedback circuit. The feedback circuit is controlled by the measurement signal and provides timed feedback signals to the generating means. The feedback signals control the generation and magnitude of the charge packets such that the charge coupled to the measurement circuit is finely balanced in a short measurement interval. The feedback means counts the number of charge packets provided during a measurement interval such that the numbers counted are representative of the sensed parameter.

Abstract: A test circuit for producing a "fail" signal if a clock path driver circuit develops an AC or DC defect. In the simplest embodiment, this test circuit comprises a time delay block for providing a delayed clock signal and its complement, with a delay that exceeds the signal propagation time through the clock receiver and driver; a latch which, in one embodiment, is clocked by the complement of the delayed clock signal to receive the drive signal and to generate pulses which do not overlap in time with the pulses of the delayed clock signal during normal circuit operation; and a gate for detecting such a pulse overlap and for generating an error signal to indicate an AC or DC fault. This circuit effectively detects AC faults at one edge of the clock pulse and one type of DC fault. In a further embodiment of the present invention, this circuit can be combined with a complementary circuit to detect AC faults at both edges of the clock pulse. In a preferred embodiment, the present test circuit is used with a plurality clock trees on a chip, and all of the error signals from these test circuits are combined to form a single chip error signal.

Abstract: The invention is concerned with the problem encountered in the packaging industry of combining the packages (50), which are as a rule provided separately, to form a package group (60), that is to say to stack a predetermined number of packages (50) one on top of the other. For this purpose, the invention employs, in a known manner, horizontal feed belts (10A, 10B) and a downstream vertical conveying means which forms the package groups (60) and from which said groups can be transferred to a horizontal delivery belt (20B). 
<??>The essential feature is that the vertical conveying means is formed from two continuous brush belts (30, 31) which run in parallel, the parallel brush rows (40) of which engage underneath the incoming packages (50) and support them. 
<??>Such a structurally simple conveying means in the form of brush belts (30, 31) can produce a substantial increase in the conveying speed and thus an increase in the number of packages (50) grouped per unit of time.

Title: Error recognition method for position-detecting systems
IPC: G01D5/26
Filed: 1988-09-24
Granted: 1991-02-27
Abstract: In such a position measuring system for measuring the relative position between two objects, the division (T) of a division carrier (M) is scanned by a scanning device (A) for generating two periodic scanning signals (Sa, Sb). These two periodic scanning signals (Sa, Sb) are supplied, on the one hand, to an evaluating device (W) for forming measurement values for the relative position between the two objects and, on the other hand, to an error detection device (F) having two trigger stages (TSa, TSb) for generating an error detection signal (FS) when the amplitude levels of the two scanning signals (Sa, Sb) are faulty. As the scanning speed of the scanning device (A) increases, however, the amplitude levels of the two scanning signals (Sa, Sb) decrease so that these amplitude levels can drop below the trigger thresholds of the two trigger stages (TSa, TSb) at high scanning speeds; the error detection device (F) outputs an error detection signal (FS) even though correct scanning signals (Sa, Sb) are still present. To avoid such an error message, the two trigger threshold voltages (TSSo, TSSu) can be regulated in dependence on the scanning speed for setting the two trigger thresholds of the two trigger stages (TSa, TSb). <IMAGE>

Abstract: A method of strengthening materials such as glass, plastic and ceramics enabling strengths to be achieved which are far in excess of what was previously known. Generally, the method comprises the placement of elongated reinforcement members (32, 34) in a molten glass substrate (30, 36, 46, 48) then cooling the substrate to the solid state. The reinforcement members may be pre-stressed in some instances and may assume a variety of arrangements within the glass substrate. The reinforcement members may be of various materials having greater tensile strength than the glass substrate. In one instance, the reinforcement members themselves may be fiber optic bundles composed of glass fibers with an outer glass cladding which melts at lower temperatures than the inner regions. The temperature is raised sufficiently to melt the cladding so as to bond together all of the bundles into an integral structure of optical quality. In another application of non-optical quality, the core may be metallic with an outer glass cladding which melts at a lower temperature than the inner regions. According to yet another embodiment, strengthened plastic members utilizing elongated reinforcing members in a plastic matrix can have an optical quality reflective surface applied by replication.

Abstract: An internal electrostatic field-generating, beam-controlling element in a cathode ray tube is formed by depositing an initially continous layer of resistive material on a substrate and applying a voltage differential across the coating to generate a field-generating current therethrough during operation of the tube. After completion of tube assembly and sealing of the tube envelope, the element is custom fine-tuned by projecting an externally-originating laser beam through the envelope wall to selectively remove portions or areas of the resistive material, thereby predeterminately distorting the electrostatic field and selectively changing the effect of the field on the imaging electron beam. This procedure readily enables both correction of perceived deficiencies in and intentional modifications to one or more characteristics of the electron beam.
