A GTL output structure having an active charging and discharging stage that actively restores internal nodes for slew rate control without the need to wait for a slow rise and fall RC time constant is disclosed herein. The novel GTL output structure includes an input stage connected to an RC network for providing slew rate control. The output stage connects between the RC network and a feedback network. The feedback network in includes an active charging stage for providing a charging current to the gate of the at least one transistor for a period of time to the value of a power supply rail and wherein the feedback network includes an active discharging stage for providing a discharge current from the gate of the at least one transistor to ground.

A quasi-complementary BICMOS circuit (46) having a clamp circuit that automatically discharges the base-collector of a pull down bipolar transistor (16) when the transistor's (16) collector voltage equalizes its base voltage. The action is immediate and does not depend on the performance of a feedback circuit to provide the timing of the arrival of the clamp signal. The clamp circuit reduces the amount of shallow saturation and quickly discharges shallow saturation after the pull down transition. The degree of shallow saturation is controllable by size selection of the clamp transistor (48). The clamp circuit also discharges the transistor's (16) base voltage to ground potential.

A page printer uses alternative internal representations for the print data in each of multiple lateral strips that make up the page. Page description language input is converted to an intermediate display list format that is sorted into display commands associated with each strip. If during input the display list representation of the data fills the memory allotted to its storage, one or more of the strips is converted from display list format to raster format and compressed using a lossless compression algorithm. If storage of compressed strips subsequently exceeds available memory, raster data is further compressed using a lossy compression algorithm. Additional display list commands are rasterized by decompressing the compressed strips, processing the new commands and recompressing the data using lossless or lossy compression as required. If the display list does not overflow memory during input, the complete strips are rasterized and compressed one at a time in the order in which they will be printed. The rasterizing time is stored. Should memory overflow at any point in the process, then the rasterizing times for the remaining strips are determined without storing the raster output. A decision can then be made for each strip to rasterize it to the print engine on the fly, precompute and store it as lossless compressed raster data, or revert to a lossy-compressed precomputed version.

A connector seal arrangement having particular adaptability for use within the insulation space between the inner wall and the cabinet wall of a household refrigerator and having a portion extending into the refrigerated space. The rear seal snaps into a watertight relationship with a recess defined at the end of the connector, whereas the front seal is disposed on an upstanding plate or flange extending from the mid-region of the connector. The inner seal is, typically, overmolded on the aforesaid plate and includes a skirt or boot in engagement with the inner surface of the inner wall of the refrigerator. Introduction of insulation presents a sealing relationship between the skirt or boot and the aforesaid inside wall surface. In order to achieve more versatility, the rear seal may include an opening presenting a fracturable membrane for the selective introduction of an electrical connector(s) depending upon total needs. In another invention form, the inner seal may be hand-fitted to a use position on the upstanding flange.

摘要:
This invention is directed to a process for removing a catalyst inhibitor from a substrate or catalytic converter containing at least one nitrogen oxide (NOx) catalyst using a phosphoric acid composition. The process is particularly suited for removing the catalyst inhibitor, arsenic, from a fly ash-coated substrate or converter. A substantial amount of catalyst inhibitor can be removed from a fly ash-coated catalytic converter without removing a significant portion of one or more of the NOx reduction catalysts in or on the substrate.

A system and method for implementing a user interface for use with Japanese characters includes a font-encoder compiler on a host computer for encoding selected text strings and creating custom fonts, and further includes an electronic device which contains a standard font and a font manager. The font manager selectively accesses the standard font and the custom fonts to display the encoded text strings on the user interface of the electronic device. Specific characters may be selected by entering a hierarchical text edit dialog, choosing a character category, selecting an articulation group and then choosing a specific character from the selected articulation group.

Embodiments relate to pedal assemblies, particularly pedal assemblies having a kickdown device that includes one or more deformable tactile domes adapted to uniformly deform or invert on application of sufficient force. This deformation, flattening, or inversion may result in a kickdown effect that may correspond to an engine kickdown. Additionally, the device may be adapted for engagement with a pedal assembly to impart a hysteresis effect as the pedal moves relative to the body.
