This invention relates to a process for preparing high-purity aromatic oligomers by effectively separating an organic layer containing aromatic oligomers or the reaction products of a polycyclic aromatic compound with formaldehyde from an aqueous layer containing an acid catalyst in a simplified manner, hitherto regarded difficult to accomplish, and obtaining high-purity aromatic oligomers from the organic layer containing a reduced amount of impurities. In separating the aqueous layer containing the acid catalyst and the organic layer containing the oligomers from the reaction mixture formed by the condensation of a polycyclic aromatic compound and formaldehyde, the emulsion phase is broken by adding a nonionic or cationic surfactant in an effective amount and an alkali in an amount sufficient to neutralize 1-70% of the acid in the acid catalyst, the organic and aqueous layers are separated and the aromatic oligomers are recovered from the organic layer.

A TMR read head with improved voltage breakdown is formed by laying down the AP1 layer as two or more layers. Each AP1 sub-layer is exposed to a low energy plasma for a short time before the next layer is deposited. This results in a smooth surface, onto which to deposit the tunneling barrier layer, with no disruption of the surface crystal structure of the completed AP1 layer.

For operating an operation target object displayed on a screen using a pointing device, a first input coordinate value indicating a position on the screen designated by the pointing device and a second input coordinate value detected discretely from, and before, the first input coordinate value are detected. A changing direction is calculated based on the first input coordinate value and the second input coordinate value, and a rotation direction is determined based on the changing direction. The operation target object is rotated in the rotation direction.

Methods and systems for fabricating an integrated BiFET using two separate growth procedures are disclosed. Performance of the method fabricates the FET portion of the BIFET in a first fabrication environment. Performance of the method fabricates the HBT portion of the BiFET in a second fabrication environment. By separating the fabrication of the FET portion and the HBT portion in two or more separate reactors, the optimum device performance can be achieved for both devices.

The separating part of the separating device receives a reactive force that occurs on the outer peripheral surface of the photoreceptor drum, at the contact point where the separating part and the photoreceptor drum are in contact.The separating device controller changes the position of the rotational supporting point so as to decrease the rotational moment M of the reactive force at the rotational supporting point of the separating device, in accordance with increase of the reactive force that occurs on the outer peripheral surface of the photoreceptor drum as the separating part is worn down.

Mesoporous membranes have shown promising separation performance with a potential to lower the energy consumption, leading to a dramatic cost reduction. Recently, an extensive effort has been made on the design of membranes which brought a significant progress toward the synthesis of well-defined porous morphologies, most of which synthesized by surfactant-template methodology. Currently, the most well-designed state-of-the-art membranes using this technique are made from metals, polymers, carbon, silica, etc. In the present invention, we demonstrate mesoporous calcium-silicate particles having superior separation capacity and optimal permeability, thereby leading to reduced energy consumption for selective separation of gases / liquids and / or the combination thereof. We explore various methods to improve the calcium-silicate membranes properties by tuning pore density during the synthesis / aging process, while favoring the formation of uniformly distributed nanopores. Lowering particle density by controlling calcium to silicon ratio along with optimizing the surface area are essential in achieving our objective.
