摘要:
A light-emitting alarm board uses thin-film EL elements which emit light of different colors individually or simultaneously, depending on the voltages applied thereon, thereby serving as display lamps for indicating the conditions of operation of a system being monitored.

The present invention provides a thin film EL device comprising an electrode layer, an emitting layer and an electrode layer formed on a substrate one over another, and an insulating layer interposed between the three layers, the emitting layer containing atoms of a rare-earth element and fluorine atoms in its host material, the atom ratio (F/RE) of the fluorine atoms (F) to the rare-earth atoms (RE) being adjusted to the range of 0.5 to 2.5, and a process for producing the EL device being characterized in that the emitting layer is prepared by forming a film under a condition substantially free from oxygen gas and/or moisture and subjecting the film to a heat treatment at a temperature of 200.degree. C. to 700.degree. C. so that the host material of the emitting layer contains atoms of a rare-earth element (RE) and fluorine atoms (F) in an adjusted atom ratio (F/RE) in the range of 0.5 to 2.5.The present invention affords a thin film EL device which emits, for example, a green luminescence with a high brightness.

An aromatic polymer film substrate, or a grafted aromatic polymer film substrate having a monomer introduced therein as graft chains is irradiated with ionizing radiation to impart a crosslinked structure. The aromatic polymer film substrate or the grafted aromatic polymer film substrate, provided with the crosslinked structure, is directly sulfonated to obtain a crosslinked aromatic polymer electrolyte membrane. The crosslinked aromatic polymer electrolyte membrane has low water uptake, high proton conductivity, low methanol permeability, high chemical stability, and excellent mechanical characteristics. A method for producing the crosslinked aromatic polymer electrolyte membrane is also provided.
摘要:
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.
摘要:
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.
