摘要:
A process for producing a microporous polymeric object to improve the degree of freedom for its various properties, compared to conventional processes, includes: mixing a block copolymer made of three or more kinds of segments with a polymer, wherein one or more of the segments are made of monomer units having a first functional group forming ionic and/or hydrogen bond, the segments constitute a co-continuous structure having mutually-independent and continuous regions due to a phase separation based on incompatibility between the segments, and the polymer has, at other than polymer chain terminals, a second functional group forming such bond with the first functional group, thereby allowing the segments to associate with the polymer at many points; forming a co-continuous structure including a region composed of the polymer and the segments due to the phase separation; and removing the polymer from the region by weakening the bond between the functional groups.

摘要:
Provided are a spiral type membrane filtering device by which an electric component can be re-used and a mounting member, as well as a membrane filtering device managing system and a membrane filtering device managing method using the same. An interconnector (42) attachable and detachable to a membrane element is provided with a sensor that detects the property of liquid such as raw water or permeated water that flows within a membrane filtering device, or a power generating section (26). Therefore, even if the membrane element is to be replaced, the sensor or the power generating section (26) can be re-used by re-mounting the interconnector 42 onto a new membrane element. Also, since there is no need to add a change to the membrane element, a conventional membrane element can be used as it is.

A liquid crystal panel of the present invention includes at least a liquid crystal cell, a first polarizer disposed on one side of the liquid crystal cell, a second polarizer disposed on the other side of the liquid crystal cell and a retardation film (A) disposed between the liquid crystal cell and the first polarizer, wherein the retardation film (A) contains a thermoplastic polymer having at least a substituent (a) represented by the following formula (I) and its in-plane retardation value (Re[750]) at a wavelength of 750 nm is larger than its retardation value (Re[550]) at a wavelength of 550 nm. The liquid crystal panel has such an effect that it reduces coloring of characters or images and a color shift even if a screen is viewed from any direction at an angle range of 360°.
