Abstract: The present structure is characterized by the electrode of a trench capacitor of a DRAM and a periphery thereof. A trench is formed adjacent to an N type region in a substrate. An insulating film is formed on the side wall of this trench and only a part of the insulating film around the upper portion of the trench is removed, forming a window. An N type polycrystalline silicon film of a lower capacitor electrode is formed over a region from the bottom of the trench to below the window, and a capacitor insulating film is formed on this polycrystalline silicon film. A polycrystalline silicon film which becomes a first upper capacitor electrode is formed on the capacitor insulating film, filling the trench up to the lower edge of the window. A monocrystalline silicon film which becomes a second upper capacitor electrode is formed on the latter polycrystalline silicon film in such a way as to contact an N type region, filling the upper portion of the trench.

Abstract: A method of seeking the number of particles of each kind in a group of particles in which plural kinds of particles are intermixed, by measuring, for example, two kinds of properties of each particle by a suitable method or device, plotting each particle on a rectangular coordinate system using the measured properties as its X and Y co-ordinates to obtain a distribution diagram, drafting boundaries to partition the distribution into clusters of the respective kinds and counting the number of particles within the boundary of each cluster, which, especially, even when the clusters of the respective particles are mutually overlapping, can reduce any deviation of the count of particles from its true value as small as possible by defining an optimum boundary.

Abstract: A compact docking station for a portable computer includes a mounting bracket assembly for supporting together as a compact unit a computer port replicating device, a DC power supply and a light for illuminating the work area of the computer. The mounting bracket assembly includes lower and upper mounting brackets that are pivotably connected to each other. The lower mounting bracket can be directly mounted on a support base such as a vehicle console. The upper mounting bracket provides a computer support surface and carries the port replicating device adjacent thereto. The upper mounting bracket is pivotable between a generally horizontal computer use position, and an upwardly angled computer removal/attachment position. This arrangement allows the computer to be positioned for use in a limited space, with minimal handling and clutter.

Abstract: An electronic voice response system includes an interface unit which couples the voice response system to a plurality of trunk groups, each including a plurality of telephone lines, which are each characterized by a set of operating parameters. The system additionally includes a control unit which is responsive to commands by an administrator of the system, for assigning configuration files which contain pre-defined sets of configuration values which correspond to the set of operating parameters to selected trunk groups. The control unit is additionally responsive to commands by the administrator for individually altering selected configuration values and for generating new state definitions for a particular trunk group. The control unit generates a state machine for each trunk group according to the assigned configuration file and responds to events received over each telephone line in accordance with the definition contained in a corresponding state machine.

Abstract: A retaining wall system is comprised of a retaining wall with an outer face. A cut is excavated in successive sections to form exposed cut faces. The exposed cut face of each successively excavated section may be temporarily supported with pneumatically applied concrete. A concrete wale is then formed horizontally along a portion of the exposed cut face of each successively excavated section. Next, tiebacks are installed through the concrete wale. The tiebacks are tested, tensioned and secured against the concrete wale. After the excavation has been completed and the retaining wall formed, an outer face is provided which extends to the full height of the retaining wall. A concrete footing is first provided at the base of the retaining wall. Next, a first tier of facing elements is erected above the concrete footing. These facing elements are then secured to a first adjacent concrete wale at a first connection point. Backfill material is placed between the first tier of facing elements and the retaining wall.
