  • Patent number: 5248894
    Abstract: A channel stop is self-aligned with a trench sidewall of a trench-isolated semiconductor architecture, so that there is no alignment tolerance between the stop and the trench wall. An initial masking layer, through which the trench pattern is to be formed in a semiconductor island layer, is used as a doping mask for introducing a channel stop dopant into a surface portion of the semiconductor layer where the trench is to be formed. The lateral diffusion of the dopant beneath the oxide and adjacent to the trench aperture defines the eventual size of the channel stop. The semiconductor layer is then anisotropically etched to form a trench to a prescribed depth, usually intersecting the underlying semiconductor substrate. Because the etch goes through only a portion of the channel stop diffusion, leaving that portion which has laterally diffused beneath the oxide mask, the channel stop is self-aligned with the sidewall of the trench.

  • Patent number: 5241213
    Abstract: A buried Zener diode has an auxiliary Zener junction access path in parallel with the force anode/cathode path. Unlike the force anode/cathode path, the auxiliary path is effectively by-passed by the current flowing between the force anode and cathode during circuit operation, so that there is no accumulation of significant resistance-current products that would otherwise mask the Zener voltage. The Zener diode has an anode region disposed in a first surface portion of a substrate. A `force` anode is formed on a first surface portion of the anode region. A `sense` anode is disposed on a second surface portion of the anode region spaced apart from the force anode. A first cathode region is disposed in a second surface portion of the substrate spaced apart from the anode region, while a sense cathode region is disposed in a third surface portion of the substrate spaced apart from each of the anode region and the first cathode region.

  • Patent number: 5229661
    Abstract: A current mode (NOR) logic circuit includes a first, fixed reference current source transistor stage coupled in circuit between a first voltage supply terminal and an input current node. A second, variable current source transistor stage is coupled in circuit between the first voltage supply terminal and the input current node. The second, variable current source supplies a variable quantity of auxiliary current to the input current node in dependence upon whether the input node sees a high logical level current or a low logic level current. The magnitude of the auxiliary current is such that the total of the auxiliary current and the prescribed reference current balances the input current being supplied to the input current node. A current switch transistor has its collector-emitter current flow path coupled in circuit between the first current source and one or more output current transistors.

  • Patent number: 5224711
    Abstract: A simulated motion board game in which a player is able to effectively simulate a continuum of sequential motion of one or more subjects contained within scenes of motion individually pictorially depicted on the faces of respective game elements. The representation of a sequence of continuous motion of the subject is independent of the order in which the tiles are placed next to one another. An edge portion of a scene immediately adjacent to the left/right hand edge of one motion tile will always provide a complementary extension of the motion within that portion of the scene immediately adjacent to the right/left hand edge of any other motion tile. As a consequence, even though the particular sequence of continuous motion will depend upon the events depicted in individual ones of the tiles, plural motion tiles placed in side-by-side adjacency with one another will always produce a continuum of motion of the subject traversing the depicted scene.

  • Patent number: 5221231
    Abstract: A motor vehicle heating/air-conditioning system of a motor vehicle has a water-removal device arranged in the fresh-air inlet duct, rising from the duct base and comprising a coarse-mesh lattice and a fine-mesh lattice resting against the latter. The water removed is carried away downwardly on the webs of the coarse-mesh lattice to the duct base which forms a water collection point with water drainage. In order to combine a favorable water-removal function with a good air-guidance function, the coarse-mesh lattice facing the incident air represents an air guide with predetermined throughflow and is pleated in a corrugated shape. A channel spanned by the fine-mesh lattice arranged in at least some areas is in each case formed between two upwardly-directed corrugation troughs. The water-removal device is placed in the region of a duct widening provided by a set-back wall portion, such that the water-removal device ends at a distance from the set-back wall portion.

  • Patent number: 5221399
    Abstract: Materials having diverse coefficients of thermal expansion are joined together by means of an adhesive film, electrically insulative mesh structure that cures at room temperature. An adhesive film bonding technique is employed to mount a printed wiring board, having a relatively low coefficient of thermal expansion, to a thermally and electrically conductive aluminum stiffener having a relatively high coefficient of thermal expansion, while maintaining the printed wiring board electrically insulated from the aluminum stiffener. A non-adhesive plastic `release` film is initially attached to a flat support substrate. A layer of electrically insulative mesh (glass cloth) is taped onto the plastic release film. The glass cloth is then impregnated with an electrically insulative adhesive that cures at room temperature. The aluminum stiffener is then placed on the adhesive-impregnated cloth layer, which is then cut to fit, using the aluminum stiffener as a template.

  • Patent number: 5220485
    Abstract: A heat removing edge guide system removes heat from a circuit board. The system includes a heat sink plate, a stationary guide fixed to the mounting surface of the heat sink plate, and a moving guide slidably mounted on a top surface of the stationary guide. Sliding of the moving guide along the upper surface of the stationary guide causes a change in the vertical distance between the mounting surface of the heat sink plate and the upper surface of the moving guide. The moving guide, the stationary guide and the heat sink plate form a thermally conductive path. A screw-adjusted side guide can also be provided to cause a wedging with a lateral wall of the chassis support and thus provide an additional heat sink path and system stability.
