摘要:
A vinyl monomer is graft polymerized on an aromatic hydrocarbon-based polymer film substrate to introduce graft chains into the substrate and thereafter a functional monomer represented by the following formula and having sulfonic acid groups or functional groups capable of conversion to sulfonic acid groups is graft polymerized to introduce the sulfonic acid groups or the functional groups capable of conversion to sulfonic acid groups: where R is an aromatic ring or an aliphatic chain; X is (1) —OH, (2) —OLi, —ONa or —OK, (3) —F or —Cl, or (4) —OCnH2n+1 where n is an integer of 1 to 7. Since the graft chains obtained by graft polymerization of the vinyl monomer can also be utilized as scaffold polymers, the graft polymerizability of the functional monomer to the aromatic hydrocarbon-based polymer film substrate is sufficiently improved to enable the preparation of a polymer electrolyte membrane that excels not only in proton conductivity and mechanical strength but also in dimensional stability.
摘要:
In a band saw, it is intended that a so-called blade drift is corrected and straight line cutting of an object is easily performed. Further, an accurate correction is realized by a simple operation. A cutting auxiliary device in the band saw in accordance with the present invention is a device used to correct a shift of a cutting line when the cutting line is shifted from a straight line in the band saw for cutting a work by using a flexible steel band. The cutting auxiliary device in the band saw has a working board having a board face for performing an operation for cutting the work and equipping an edge port plate for passing the flexible steel band on the board face; a working board support portion for supporting the working board so as to be horizontally rotated with the flexible steel band as a center; a laser projector attached to a band saw main body side and projecting a laser beam so as to be overlapped with the shifted cutting line when the work is straightly cut by the flexible steel band on the working board and the cutting line is shifted from the straight line; and a working board fixing portion for fixing the working board to a receiving portion of the band saw main body side in a place which the straight line of the laser beam projected from the laser projector and a mark on the working board are aligned.
摘要:
The present invention is generally drawn to novel isolated therapeutic agents, termed resolvins, generated from the interaction between a dietary omega-3 polyunsaturated fatty acid (PUFA) such as eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA), oxygenases and the analgesic aspirin (ASA). Surprisingly, careful isolation of compounds generated from the combination of components in an appropriate environment provide di- and tri-hydroxy containing derivatives of EPA and DHA containing compounds having unique structural and physiological properties. The present invention therefore provides for many new useful therapeutic di- and tri-hydroxy derivatives of EPA or DHA (resolvins of the E series and D series) that diminish, prevent, or eliminate gastrointestinal conditions, for example, such as colitis. The present invention also provides methods of use, methods of preparation, and packaged pharmaceuticals for use as medicaments for the compounds disclosed throughout the specification.
摘要:
A compact vehicle-mounted electrical outlet box offering a reliable plug blade detection function. The electrical outlet box is formed from synthetic resin rectangular case 1 which includes body 2 and cover 3. A pair of electrical plug blades 100 and 101 are inserted into plug blade insertion slots 5 located on the front surface of case 1 through which the plug blades contact two blade receiver parts 10. The forceful contact of plug blades 100 and 101 rotate two pivot levers 12 which convert the insertion force of plug blades 100 and 101 to a directional force. Two return springs 13 apply pressure to pivot levers 12 in a direction opposite to that applied by the insertion of plug blades 100 and 101. Printed circuit block 14, which is comprised of circuit base plate 14a to which each microswitch 14b is installed, is housed within case 1. The two pivot levers 12 are located at the approximate mid-point of body 2 between the two mutually facing blade receiver parts.
摘要:
A polymer film substrate is irradiated with ions to make a large number of nano-sized through-holes and the substrate is further irradiated with an ionizing radiation so that a functional monomer is grafted or co-grafted onto a surface of the film and within the holes; in addition, the sulfonic acid group is introduced into the graft chains, thereby producing a polymer ion-exchange membrane that has high oxidation resistance, dimensional stability, electrical conductivity and methanol resistance, as well as an ion-exchange capacity controlled over a wide range.
