To provide a parallel ruler device with which it is easy to obtain a plate material of a constant width having parallel sides. Also, to make it possible to easily carry out a precision adjustment of an amount of parallel movement of a ruler face by means of a visual observation. Also, to enable a precision adjustment of a desired dimension in both a positive direction and a negative direction with a position fixed once as a base point. In a parallel ruler device which includes a moving body movable along a sliding portion provided on a main body, and in which the moving body has a sliding counterpart making contact with the sliding portion, and is configured in such a way that a ruler face set in a portion other than the sliding counterpart moves in parallel along with the movement of the moving body, an inclined sliding portion 12 is set in a direction intersecting a longitudinal direction of the main body 11, a direction of the ruler face 17 of the moving body is set in a direction intersecting that of the sliding counterpart 16 of the moving body 15 which slides along the inclined sliding portion, and the ruler face of the moving body is configured in such a way as to move away from or near to the main body along with the movement of the moving body.

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.

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.

Influence of drift of a metal band in a band saw is corrected, so that an intended shape can be easily cut out. In a band saw of cutting a workpiece using a flexible metal band, an auxiliary device used in cutting the workpiece includes a body that is disposed on a surface of a work table of the band saw, and has a passage portion of the metal band at one end; a correction mechanism interposed between the body and the work table to shift a direction of the body in a direction deviated from a virtual cutting line by the metal band to correct deviation of a cutting direction by the metal band; and a clamp unit for clamping the body to the work table; wherein part of the body having a shifted direction is parallel to a direction of feeding the workpiece to the metal band.

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.

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 γ-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.

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.
