Preferred separating plates are produced with compositions comprising graphite and phenolic resin.
Abstract:
The invention relates to a binder for an electrode material of an electrochemical device, said binder comprising an aqueous dispersion (I) containing a water-dispersible resin; (I) containing at least one of a thermoreversible thickening vinylic polymer (A) having reversibility of hydrophilicity and hydrophobicity at a certain transition temperature (T) and a water-dispersible resin (B) having a fluorine atom-containing unit; an electrode material dispersion for an electrochemical device, which comprises the said binder and an electrode material (E); an electrode for an electrochemical device, formed from said electrode material dispersion; and a primary cell, a secondary cell, an aluminum electrolytic capacitor or an electric double layer capacitor, which has said electrode.
Abstract:
A thermal switch for automatically opening a circuit when the ambient temperature exceeds a predetermined level is disclosed which utilizes a sensing pellet formed of an organic-glass bead mixture. The organic-glass bead pellet retains a pair of leads in contact with each other when the ambient temperature is below the melting temperature of the organic material. The addition of the glass beads to the temperature sensing pellet allows the compressive strength that is needed to hold the leads together to be more reliably controlled. In the process of combining the organic material and the glass beads, to form the pellet, the organic material is first melted so as to flow around the beads. Manufacture of the thermal-sensing pellet in this manner eliminates the voids which occur in the pressed organic pellets that are conventionally used in thermal sensing devices. The elimination of these voids increases the strength of the otherwise relatively fragile pellet thereby improving reliability of thermal switches which utilize the improved pellet of the present invention.
Abstract:
A method used for forming ceramic matrix composite components includes several steps. The method comprises arranging a layup of a predetermined number of prepreg ceramic plies on a layup too and a plurality of different stages to debulk and consolidate the layup.
Abstract:
Sound-attenuating mufflers and muffler inserts, and systems and methods for fabricating such muffler inserts. Continuous fiberglass roving is fed to a pneumatic jet head which fluffs the roving and presents the fluffed roving to a delivery wand at the exit end of the jet head. A jet head/wand assembly is moved along a three-dimensional path such that the wand delivery tip travels along a predetermined three-dimensional path inside a mold thereby depositing the continuous, fluffed fiberglass strands in the mold along the predetermined path. A terminal end portion of a liquid resin conduit is mounted to the fiberglass-dispensing wand, as part of the delivery tip, and drip-feeds liquid resin onto the fiberglass as the fiberglass is being deposited in the mold. The undulating, up and down movement of the delivery tip produces a wave-like undulating pattern in the appearance of the rovings in the resulting molded product.

Abstract:
The present disclosure relates to an integrated liner-based system having an overpack and a liner provided within the overpack, the liner comprising a mouth and a liner wall forming an interior cavity of the liner and having a thickness such that the liner is substantially self-supporting in an expanded state, but is collapsible at a pressure of less than about 20 psi. The liner and overpack may be made by blow molding the liner and the overpack at the same time using nested preforms.
Abstract:
A three-dimensional shaped object manufacturing method of the invention is a three-dimensional shaped object manufacturing method for manufacturing a three-dimensional shaped object by laminating layers, including: a layer forming step of forming each of the layers by using a layer-forming composition containing particles and a solvent; a first liquid application step of applying, onto the layer in a state of containing the solvent, a liquid that is used to form a solidified part; and a solvent removal step of removing the solvent from the layer. In the first liquid application step, it is preferable that the liquid is applied to a surface of the layer containing the solidified part, in a region that does not overlap the solidified part when the layer is seen in plan view.
Abstract:
A method for producing activated carbon includes heating a phenolic novolac resin carbon precursor at a carbonization temperature effective to form a carbon material, and reacting the carbon material with CO2 at an activation temperature effective to form the activated carbon. The resulting activated carbon can be incorporated into a carbon-based electrode of an EDLC. Such EDLC can exhibit a potential window and thus an attendant operating voltage of greater than 3V.
Abstract:
An automotive assembly comprises a sheet molding composite (SMC) element comprising an SMC sheet body shaped into a generally smooth functional section and at least one generally planar bonding section. The bonding section comprises a textured surface impressed as a result of molding the SMC sheet body in a compression molding tool having a corresponding textured pattern. The textured surface has a predetermined surface roughness for increasing the effective surface area of the bonding section relative to a non-textured surface. The predetermined surface roughness is in a range from 0.25 Ra (μm) to 8.5 Ra (μm). A second element has a secondary bonding surface adjoining the bonding section of the SMC element. An adhesive joins the secondary bonding surface to the bonding section without requiring any pre-treatment of the bonding section.
