Title: Active matrix LCD and method of producing the same
Inventor: TANAKA HIROAKI
IPC: G02F1/1343
Filed: 1998-01-26
Granted: 2002-05-11
Abstract: An active matrix LCD (liquid crystal display) using thin film transistors as switching devices and a method of producing the same are disclosed. When a drain bus line and a pixel electrode are to be formed, a transparent conductive film and a low resistance metal film are sequentially laminated in a double layer structure. Only the metal film is removed from the pixel electrode by side etching effected via holes formed in the pixel electrode. This allows a low resistance drain bus line and a transparent pixel electrode to be formed by a single photolithographic step. As a result, the wiring resistance of the LCD can be lowered without increasing the number of times of photolithography, allowing the LCD to be provided with a wide screen.

Title: Preparation of high activity catalysts
Inventor: MAULDIN CHARLES HARRISON
IPC: B01J23/889
Filed: 1998-08-17
Granted: 2002-06-21
Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide conversion reactions, especially a Fischer-Tropsch catalyst, use of the catalyst for conducting such reactions, especially Fischer-Tropsch reactions, and the composition produced by said process. In the preparation of the catalyst, a solution of a polyol is employed to impregnate and disperse a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron group metal such as iron, cobalt, or nickel, or in a preferred embodiment both a compound or salt of rhenium and a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron group metal such as iron, cobalt, or nickel onto a refractory inorganic oxide support, e.g., titania. The rhenium, when present only in small amount permits full and complete reduction of the catalytic metal, or metals, dispersed by the polyol. Higher catalyst activities with lower rhenium loadings are thus achieved than in previous preparations where higher concentrations of rhenium were required to both effectively disperse, and reduce the catalytic metal, or metals, during the preparation. Surprisingly, as little as about 1/10 of the rhenium is required to accomplish the reduction promotion where the dispersion is effected with the polyol.
