    摘要: An interface adapter enables a replacement controller to be mechanically received in a housing configured for an older model controller having a larger volume. Moreover, the interface adapter enables terminals of the replacement controller having a first configuration to be connected to the contacts of a housing connecter having a second configuration configured to couple with contacts of the older model controller. The interface adapter includes a faceplate having a central aperture for receiving the replacement controller and a pair of sideboard printed circuit boards (PCBs) positioned perpendicular to a surface of the faceplate in spaced parallel relation on opposite sides of the central receiving aperture. A main PCB is electrically and mechanically connected between the sideboard PCBs. The main PCB and the sideboard PCBs have contacts adjacent their ends opposite the faceplate. A first connector has a first part affixed to the main PCB and has contacts electrically connected to the contacts of the main PCB and the sideboard PCBs. The first connector has a second part electrically connected to terminals of the replacement controller via flexible conductors. The replacement controller and the interface adapter are assembled by inserting the replacement controller through the central receiving aperture of the faceplate and connecting the first and second parts of the first connector. The assembled interface adapter is inserted into the housing and the contacts of the main PCB and the sideboard PCBs are moved into connecting engagement with the contacts of the housing connector.

    摘要: An improved swimming pool cleaner of the type for submerged random travel generally along the floor and sidewalls of a swimming pool to dislodge and collect debris. The pool cleaner comprises a frame and associated housing through which a suction mast extends with a collection bag mounted at the upper end thereof. First and second wheels are mounted for rotation on a common axis on opposite sides of the housing forwardly of the suction mast, and third and fourth wheels are mounted for rotation on a common axis on opposite sides of the housing rearwardly of the suction mast. The first and second wheels are driven by a water-powered drive train within the housing, and the third and fourth wheels are mounted for freewheeling rotation. A forward end of an upper surface of the housing has a substantially linear sloping portion to reduce the tendency of the cleaner to lift off the submerged surfaces of the swimming pool as the first and second wheels propel the cleaner in the forward direction.

    摘要: A method for forming CMOS transistors and ferroelectric capacitors on a single substrate (10) with improved yield begins by forming CMOS transistors (37a, 37b, 40, 42). A hydrogen anneal using 4-5% hydrogen and a remainder nitrogen is performed to reduce dangling atomic bonds at the gate dielectric/substrate interface of the transistors (37a, 37b, 40, 42). A silicon nitride layer (48) is then deposited over the transistors and on the backside of the wafer substrate (10) in order to substantially encapsulate the effects of the hydrogen anneal to the CMOS transistors (37a, 37b, 40, 42). Ferroelectric capacitor layers (54, 58, 60, 62, 64) are formed overlying the nitride layer (48) where the ferroelectric capacitor layers (54, 58, 60, 62, 64) are oxygen annealed in pure O.sub.2. The nitride layer (48) prevents the transistor hydrogen anneal from damaging the ferroelectric material by containing the hydrogen.

    摘要: A capacitor with a metal-oxide dielectric layer is formed with an upper electrode layer that is electrically connected to an underlying circuit element. The capacitor may be used in forming storage capacitors for DRAM and NVRAM cells. After forming an underlying circuit element, such as a source/drain region of a transistor, a metal-oxide capacitor is formed over the circuit element. An opening is formed through the capacitor and extends to the circuit element. An insulating spacer is formed, and a conductive member is formed that electrically connects the circuit element to the upper electrode layer of the metal-oxide capacitor. Devices including DRAM and NVRAM cells and methods of forming them are disclosed.

    摘要: A low lift pallet truck so configured, in its lowered and unladen mode, that entry into and exit from double-faced pallets is made without contact of its fork wheels and the pallet's bottom boards. In this mode, support wheel assemblies fixedly mounted on each side of the truck fork frame, position the forks above their normal lowered height. Lift linkage rod assembly springs retract the fork wheels upward into the fork structure clear of the floor. Therefore with the truck's drive wheel and support wheels bearing its weight, the truck can be moved with its forks positioned above the pallet bottom boards free of interference. When the forks are properly positioned in the pallet, operator actuation of the lift function causes the truck fork frame to rise and move the lift linkage to drop the fork wheels to floor contact. Simultaneously the support wheels move upward with the fork frame and no longer carry the truck's fork end weight loadings. Lifting is stopped when the pallet is clear of the floor. The truck suspension is now in the mode common of most low lift pallet trucks. Deposit of the pallet by actuation of the truck lowering control, returns the truck to its original lowered and unladen counter-balanced configuration and exit from the pallet is made without contact with the pallet bottom boards. Driver control actions required in operation of the trucks of the embodiments of this invention are identical to those of most prior construction trucks.

    摘要: A high-permittivity dielectric capacitor (28) having a refractory-metal oxide layer (16) framing the first electrode (14) of the capacitor (28) and separating a high-permittivity dielectric layer (24) from an insulating layer (12) underlying the capacitor (28). The high-permittivity dielectric layer (16) makes contact with the first electrode (14) through an opening (18) in the refractory-metal oxide layer (16). The refractory-metal oxide layer (16) separates the high-permittivity dielectric layer (24) from the insulating layer (12) in all regions away from the opening (18) in the refractory-metal oxide layer (16). During fabrication of the capacitor (28), when the high-permittivity dielectric layer (24) is patterned, the refractory-metal oxide layer (16) provides an etch-stop.

    摘要: The turn-on delay of a cold cathode gas tube, such as a gas laser, is significantly reduced by the inclusion of an electric field concentrator in a region of the tube between the tube anode and cathode. The concentrator can take the form of a projecting conductive member having a sharp corner, linear or curved knife edge, needle like points, or combinations of such geometries.
