A liquid crystal display device includes: a pair of substrates each disposed on each opposing plane and having an electrode of a predetermine shape; a vertical alignment film formed covering each of the electrodes of the pair of substrates and subjected to a rubbing alignment process; an insulating film formed between the electrode and the vertical alignment film in each of the pair of substrates and having necessary insulation; and liquid crystal sandwiched between the pair of substrates and having a negative dielectric anisotropy Δ∈ and a specific resistance ρc1 of 1.0×1014 Ωcm to 1.0×1015 Ωcm, wherein a structure between the electrodes is selected to satisfy conditions of T≦5.2×τc1×1/(1×1012) sec and T≦500 sec, where T is a charge resident time until a display image disappears completely after static electricity of 10 kV is applied between the electrodes of the pair of substrate and the display image is tuned on. It is possible to prevent alignment defects to be caused by static electricity generated by rubbing of a liquid crystal display device.

In an exhaust gas recirculation system for an internal combustion engine, which includes a turbocharger; a high-pressure EGR unit; a low-pressure EGR unit; a high-pressure EGR valve; and a low-pressure EGR valve, first, the opening amount of the high-pressure EGR valve is controlled in a feedback manner, and, then, the opening amount of a low-pressure EGR valve is controlled in a feedback manner in a transitional operation period in which the operation mode of the internal combustion engine is changing. In this way, the intake air amount is promptly adjusted to the target intake air amount without causing hunting.
摘要:
An EGR system includes a high-pressure EGR unit and a low-pressure EGR unit. During the steady operation of an internal combustion engine, the high-pressure EGR gas and the low-pressure EGR gas are mixed with each other at a mixture ratio, in which the ratio of the high-pressure EGR gas amount to the entire EGR gas amount is higher than that in a known mixture ratio, and then recirculated back to the internal combustion engine. In the engine speed-up transitional operation period, the opening amount of a high-pressure EGR valve is adjusted to the opening amount that is much smaller than the target opening amount corresponding to the target operation mode. Thus, it is possible to suppress occurrence of the situation where the entire EGR gas amount is excessive in the period in which the low-pressure EGR gas amount does not decrease by a sufficient amount.
摘要:
A method for simply and efficiently separating substances by utilizing a specific flow behavior in a non-turbulent flow, i.e. a laminar flow, in a micro-channel is disclosed. A mixed solution containing at least two kinds of solute molecules which are different from each other in molecular weight and/or molecular sharp, or at least two kinds of solutions containing their respective solute molecules are flowed into a micro-channel to form a non-turbulent flow. A physical action is given to each molecule by changing the state of flow, thereby causing different behaviors among the different solute molecules. By utilizing this behavior difference, molecules of a specific kind are gathered in a specific region in the channel for separation.

The method forms a transparent polishing pad by first step forming a plurality of openings through a disk-shaped pad body. The plurality of openings is distributed about the disk-shaped pad body and a transparent window within a portion of the pad body and the transparent window. Then sealing the openings in the transparent window with a transparent material allows transport of polishing fluids through the openings in the disk-shaped pad body and prevents transport of the polishing fluids through the transparent window.

A liquid crystal display device using a low duty ratio driving method with a duty ratio not smaller than 1/16 is manufactured in the following manner. A first substrate is prepared having a first electrode of a predetermined shape. A second substrate is prepared having a second electrode of a shape different from said predetermined shape, the second electrode having signal line electrodes smaller in number than those of the first electrode. An insulating film having necessary insulation is formed on each of the first and second electrodes. First and second vertical alignment films are formed above the first and second substrates, respectively, the first and second vertical alignment films covering the first and second electrodes, respectively. A rubbing process is executed only for the second vertical alignment film. The first and second substrates are disposed facing each other, and liquid crystal having a negative dielectric constant anisotropy is disposed between the first and second substrates. It is possible to prevent alignment defects to be caused by static electricity generated by rubbing of a liquid crystal display device.

摘要:
Eight-bit digital image data of R, G and B output from an image data memory are corrected by conversion controllers to meet characteristics of a liquid crystal panel. The corrected data are input to a liquid crystal drive circuit as digital image data, and an image is displayed on the liquid crystal panel. A LUT stored in a LUT reference processor stores data (addresses) by a number that makes it possible to refer to input image digital data at one to one. A random number generator is for generating random numbers and supplying the random numbers to a round-to-integer processor as threshold value data. The round-to-integer processor compares the data referred to by the LUT reference processor with the threshold data, and carries out a round-to-integer processing.
