Abstract: A modular, retrofittable, and portable drain water recycle system, for installation into, and removal from, an existing host plumbing system having a host water supply, a sink, a tub or shower, a toilet, and a sewer. The modules include a drain fixture module, a system control module, and a storage tank module, all interconnectable. Gray water is collected from a tub, shower, or sink, by a drain fixture module, and is stored in a storage tank module for reuse in flushing a toilet. The drain fixture module and storage tank module are controlled by the system control module. Capacity can be altered by adding or removing storage tank modules. Different host systems can be accommodated by adding or removing drain fixture modules and system control modules. Drain fixture modules replace or are installed nearby existing P-traps, normally accessible. Storage tank modules and system control modules are of such shape and size as to fit under a typical sink inside the sink cabinet.

Abstract: A piercing clamp for sheets of paper and the like, it includes a piercing jaw containing a piercing pin, and a holding jaw, and is urged closed by a spring. It is self piercing. Once a sheet of paper is pierced within the clamp, it retains its position relative to the clamp whether the clamp is open or closed. A guard may also be included to guard the piercing pin. The piercing clamp has great utility in a hanging clipboard. By piercing divider sheets within the clamp, other sheets may be inserted between the dividers without being pierced, allowing the piercing clamp to be used as a flier.

Abstract: A CMOS low power Schmitt type input buffer for a dynamic random access memory (DRAM) circuit. This buffer is further characterized in that a falling edge on the input has better than average noise immunity and has a slightly longer propagation time through the buffer than a rising edge.

Abstract: The present invention is a contact etch method which simultaneously smoothes a reflowed oxide profile so that separate phanarization photoresist coat and etch steps are unnecessary. This method is characterized in that it is fast, uses only one photoresist mask layer, etches contacts to poly and to substrate simultaneously, is done entirely with plasma etch technology in a single reactor, and builds up less polymer in the plasma reactor. The novel method eliminates a coat and an etch step, improving yield and reducing fabrication time. Lower polymer buildup means higher yields due to a cleaner process, and less downtime for reactor chamber cleaning.

Abstract: One or more selected fuses among a plurality of fuses are blown by using electronic means to discharge a capacitor and route the resulting current spike to the selected fuse. Also, a driver output current is approximated by measuring suply currents for an unloaded output and for a loaded output and comparing the two supply currents. If the driver output is connected to the active end of a fuse, the supply current demanded by the driver indicates a state of the fuse. The invention finds particular utility when used on an integrated circuit memory array with fuse activated redundancy.

Abstract: An arithmetic logic unit (ALU) cell, having a narrow pitch for straightforward cascading and integration with a memory array or similar device, also able to efficiently perform AND, NAND, OR, NOR, XOR, XNOR, INVERT, SET and CLEAR operations, and ripple carry addition. The ALU has particular utility in a multiport random access memory (RAM) based multiprocessor.
