Patent KR-940009744-B1 (KR)
Title: Input scanning method
Inventor: NO KYONG-TAE
IPC: G06F3/02
Filed: 1992-07-08
Granted: 1994-10-17
Abstract: The adaptive method for scanning a logic input scans after converting an unstable logic input into a stable logic input. The method includes the steps of: sampling the logic input, shifting it in a register and checking the shifted bit state; if all bits are 0, processing as a generation of a trailing edge by understanding the input logic as a 'low' state if an input state just before is a 'high' logically, or understanding as the present logic state if not the 'high' logically; understanding the input logic if all bits are 1 ; understanding the input logic as the present logic state if bits have 0 and 1 mixed.

Granted: 2001-06-01
Abstract: A method of forming a capped and borderless contact of polysilicon on a body of a semiconductor material includes depositing a layer of undoped polysilicon on the surface of the body and forming an opening therethrough to the surface of the body. The side walls of the opening are then coated with a layer of silicon nitride and the opening is then filled with doped polysilicon which forms the contact. The doped and undoped polysilicon are heated in an oxidizing atmosphere to grow a layer of silicon dioxide thereon having a thicker portion over the doped polysilicon then over the undoped polysilicon. The silicon dioxide layer is etched to remove the thinner portion leaving the thicker portion over the doped polysilicon as a capping layer. The undoped polysilicon is then etched away and a layer of a dielectric material is deposited on the body and surrounding the doped polysilicon contact. <IMAGE>

Title: Solar Membrane Distillation System And Method Of Use
Inventor: AL-ARIFI IBRAHIM
Filed: 2011-03-29
Abstract: A water distillation system includes a membrane distillation unit which produces desalinated water from feed water comprising salt water. The system also includes a primary water heater which raises a temperature of the feed water upstream of the feed water entering the membrane distillation unit. The system additionally includes an evaporative cooler which lowers a temperature of a coolant upstream of the coolant entering the membrane distillation unit.
