The present invention relates to an unsaturated fluorinated ether or amine compound of formula (I) with low global warming potential and method of making the compound (I), where R.sub.H.sup.1 is and R.sub.H.sup.2 are independently selected from H or CH.sub.3, wherein when R.sub.H.sup.1 is CH.sub.3 then R.sub.H.sup.2 is H and when R.sub.H.sup.2 is CH.sub.3, then R.sub.H.sup.1 is H; X is O or N and when X is O, then n is 1 and R.sub.f is a linear or branched perfluorinated alkyl group comprising 1-10 carbon atoms and optionally comprising at least one catenated O or N atom; X is N, then n is 2 and (i) each R.sub.f is independently selected from a linear or branched perfluorinated alkyl group comprising 1-8 carbon atoms and optionally comprising at least one catenated O or N atom, or (ii) the two R.sub.f's are bonded together to form a ring structure optionally comprising at least one catenated O or N atom, wherein the ring of the ring structure consists of 5-7 atoms, no more than 10 carbon atoms, and is perfluorinated. The applications of the compound include solvent cleaning, electrolyte solvents or additives, heat transfer, and vapour phase soldering.
DETERGENT COMPOSITION AND AEROSOL COMPOSITION OF SAME
A novel detergent composition and an aerosol composition are nonflammable, has little hazard of ignition or risk during fire, and do not require a hazardous material storage warehouse, and which are not subject to legal restrictions with respect to amounts that may be stored when the detergent composition is to be used in large quantities, and which moreover are of low toxicity, and which while having properties such that the environmental impact thereof in terms of depletion of the ozone layer and so forth is small, as well as washability and drying characteristics equivalent to those of conventional detergent compositions which are used as brake cleaner, and have very little tendency to attack rubber and/or resin, a detergent composition and an aerosol composition of same are made to contain (Z)-1-chloro-3,3,3-trifluoropropene and C.sub.4F.sub.9OCH.sub.3, C.sub.3F.sub.7OCH.sub.3, 1,1,2,2-tetrafluoro-1-(2,2,2-trifluoroethoxy)ethane, or other such HFE-type nonflammable fluorinated-type solvent.

Cleaner composition, cleaning aerosol, and method for cleaning contaminated part
The present invention provides a cleaner composition having excellent cleaning properties and appropriate drying properties. The present invention is a cleaner composition including: (A) a hydrofluoroolefin having a boiling point of 30 C. or more and less than 100 C.; and (B) at least one of a perfluoropolyether having a boiling point of 100 C. or more and a hydrofluoroolefin having a boiling point of 100 C. or more, where a mass ratio of the component (A) and the component (B) is 99:1 to 55:45.
COMPOSITE AND METHOD FOR MANUFACTURING SAME
A composite object with more complete and stronger adhesion between the constituent parts includes a substrate and a plastic member formed on a surface of the substrate. The substrate can be made of memory metal. Nano-holes are formed on the surface of the substrate. The composite further includes a combining layer. The combining layer is positioned between the substrate and the plastic member. The nano-holes are at least partially filled with the combining layer, unfilled holes being filled with the plastic constituent in the molten state. The disclosure further provides a method for manufacturing the composite.

NONFLAMMABLE LIQUID COMPOSITION AND ITS APPLICATIONS
To provide an industrially and environmentally more preferable nonflammable liquid composition having a fluorine compound reduced, as compared to previously known nonflammable liquid compositions.
A liquid composition is used, which includes a flammable liquid and a fluoroiodoalkane represented by the following formula (1):
##STR00001##
(in the formula, X each independently represents H or F, and n represents an integer of from 0 to 5), and which is characterized in that the total amount of the above-mentioned flammable liquid and the above-mentioned fluoroiodoalkane is from 95 to 100 wt % of the entire amount of the above-mentioned liquid composition.
Connector for non-cylindrical composite tubing
A connector may couple to a non-cylindrical composite tubing having at least two lateral sides disposed in parallel and an open end. The connector may comprise first and second bonding plates adhered to an inner surface of the two lateral sides via an epoxy adhesive uniformly distributed. The first and second bonding plates may each have a distal lateral face defining a plurality of first threaded holes accessible at the open end of the composite tubing. The connector may also comprise an end plate having a plurality of first and second slotted holes disposed substantially in parallel and each aligned with an associating one of the first threaded holes. The connector may also comprise end plate fasteners loosely inserted through the first and second slotted holes and engaged with the first threaded holes. The end plate may also comprise one or more attachment points.
