Abstract: A polymer electrolyte membrane produced by a process in which a monofunctional vinyl monomer into which sulfonic acid groups can be introduced and a vinyl monomer having a halogen at a terminal are co-grafted into a polymer base film that has been exposed to an ionizing radiation, and the base film is exposed again to an ionizing radiation and/or heat treated so that the terminal halogen is eliminated to introduce a crosslinking structure in which the graft molecular chains are bound together.

Abstract: A clamp tool for woodwork or metalwork in which a screw mechanism is not apart away from a shaft and is not exposed is disclosed. In the clamp tool, a pair of clamping brackets is disposed on a shaft apart from each other and at least one clamping bracket is movable along the shaft to fasten a workpiece in cooperation with the other clamping bracket. Here, a female screw constituting a screw mechanism is disposed at one end of the shaft, a male screw constituting the screw mechanism is rotatable in a slide cylinder disposed outside at the end of the shaft so as to be screwed to the female screw, a handle for rotationally manipulating the male screw is disposed, and a guide portion is disposed between the shaft and the slide cylinder so that the female screw does not rotate but goes straight with the rotation of the male screw so as to allow the clamping bracket disposed outside the slide cylinder to move along the shaft.

Abstract: Polymer ion-exchange membranes having outstanding electrical conductivity, water retention and oxidation resistance are produced by the steps of uniformly mixing an organic high-molecular weight resin with functional inorganics having the abilities to promote graft polymerization of polymerizable monomers, adsorb water and conduct protons, irradiating the resulting functional inorganics/polymer membrane to initiate graft polymerization or graft copolymerization of polymerizable monomers having functional groups, and then introducing sulfonic acid groups into the graft chains.

Abstract: 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.

Abstract: The objective of the invention is to solve the problems of conventional polymer electrolyte membranes, including small ion-exchange capacity and low oxidation and methanol resistance. A polymer film substrate is irradiated with ?-rays, electron beams or other radiations to perform multi-graft polymerization with functional monomers and then the polymer film substrate containing the grafted molecular chains or the graft molecular chains into which sulfonic acid groups have been introduced is crosslinked by irradiation to produce a polymer electrolyte membrane that has outstanding oxidation resistance, dimensional stability, electrical conductivity and methanol resistance and which can be controlled in ion-exchange capacity over a wide range.

Abstract: The improved electrolyte membrane which is produced by grafting a styrenic monomer and bis(vinylphenyl)ethane as monomers to a polymer substrate and then introducing sulfonic acid groups into the graft side chains formed has improved oxidation resistance and good adhesion to electrodes. The polymer substrate is preferably made of a fluorocarbon polymer or an olefinic polymer. The styrenic monomer is preferably one or more species selected from the group consisting of styrene, ?-methylstyrene, vinyltoluene, and trifluorostyrene.

Abstract: In an electrolytic cell a membrane consisting of dielectric material such as an organic polymer, which separates two chambers of the electrolytic cell from each other is produced using an etching solution which is provided in one of the chambers, contains active etching ions, while the other chamber contains a solution, which does not have an etching action. An electrical field is generated through the membrane. The etching progresses along ion tracks in the membrane and first produces one funnel-shaped pore per ion track. Immediately prior to the breakthrough, the ions, which do not have an etching action, begin to penetrate the still existent thin layer with fine pores—the active layer—and displace the ions with an etching action. An intensified electric current, driven by the adjacent field, is established and the etching process at the bottom of the pore shifts sideways according to the concentration of etching ions still present. The process is stopped by deactivating the field and flushing the membrane.

Abstract: For the purpose of changing the geometry of and spacing between loop coils incorporated into an RF coil without moving the RF coil, a first plurality of loops having a geometry optimized for a square sum method employing a phased array, and a second plurality of small loops having a geometry optimized for a sensitivity encoding method are switched by switching elements for an open/close operation using a diode, and at the same time, a first decoupling means and a second decoupling means are switched.
