Abstract: A method of providing an electrode wiring of titanium contacting to the upper electrode of a capacitance element can prevent characteristic deterioration, invade capacitor insulation film and react. On a substrate 1, there are a lower electrode 2, a capacitor insulation film 3, an insulation film 5 for coating, and the first partial film 7a on an upper electrode 7 which fills the second opening 6 (an opening for regulating capacitance) which is formed in the insulation film 5. A capacitor element is composed of the lower electrode 2, the capacitor insulation film 3, and the first partial film 7a. The upper electrode 7 includes the first partial film 7a which contacts a capacitor insulation film 5, and the second partial film 7b which does not contact the film 5. The second electrode wiring 11 has a lower film 11a of titanium and an upper film 11b of aluminum alloy. Because the second partial film 7b contacts the first partial film 7a of the upper electrode 7, the diffusion of the titanium and others which invade from the second electrode wiring 11 to the capacity insulation film 5 can be prevented.

Abstract: In the past, the hydrocellulose sheet, which could be flushed in the toilet, did not have good hydrolyzation and high strength. The heat-resistance has never been satisfied and the hydrolyzation will reduce in cold water. According to the solving method, using a modified polyvinyl alcohol as a linker with an aqueous solution containing water-soluble organic salt, water-soluble inorganic salt and/or water-soluble boron compound is impregnated whereby wet strength of the fibrous sheet can be maintained. The fibrous sheet thus obtained is excellent in hydrolyzation and strength, and its hydrolyzation and strength are not lowered even at high temperatures. Furthermore, it is excellent in hydrolyzation even in the cold water.

The measured signal strength can be computed by dividing the energy of the desired signal with the energy of the noise. The signal strength of the desired signal can be estimated as the maximum likelihood estimate of the actual signal strength Α. The signal strength of the desired signal can also be estimated based on the expected value of the energy of the desired signal. The signal strength of the desired signal can further be estimated based on the expected value of the energy of the desired signal and accounting for a predetermined bias.

Title: Process of manufacturing high pressure hydrogen-enriched gas stream
Inventor: WALLACE PAUL S
IPC: C01B3/50
Filed: 1999-12-22
Granted: 2002-09-01
Abstract: The invention is a process to recover a high pressure hydrogen rich gas stream from synthesis gas. The synthesis gas is separated into a hydrogen-enriched permeate and a hydrogen-depleted non-permeate by use of a membrane. The permeate experiences a substantial pressure drop of between about 500 psi (3.45 mPa) to 700 psi (4.83 mPa) as it passes through the membrane. The pressure of the non-permeate gas is unchanged by the membrane. The non-permeate gas pressure is reduced to between about 200 psi (1.38 mPa) and about 500 psi (3.45 mPa) for use in a combustion turbine. The hydrogen-rich permeate is compressed to between about 800 psi (5.52 mPa) and 3000 psi (20.685 mPa) for use in subsequent operations, i.e., for use in hydrotreating of crude oil. The non-permeate gas is expanded in a manner to provide energy which is used to compress the permeate gas.
