摘要:
A toilet accessory (10) having readily detachable toilet seat (14) and toilet lid (16). A hinge shaft (74) is supported by a pair of posts (72) to protrude away from the housing (12). The hinge portions of the toilet seat and the toilet lid are provided with elastic collars (84) of C-shaped cross-section and are snap-fitted on the hinge shaft (74). When the toilet seat and the toilet lid are to be removed for washing or cleaning, they can be readily dismounted only by pulling with hands. To re-install, the hinge portions readily snap-fit on the hinge shaft by bringing the elastic collars (84) in contact with the hinge shaft (74) and by pressing down the hinge portions. Since the hinge shaft (74) and the posts (72) are exposed out of the housing (12), they can be easily accessed for cleaning.

In a method of removing a component from a wiring board to which the component is attached by heat-softenable resin, the improvement is provided of, after softening of the resin by heat and removal of the component, removing residual resin remaining on the board at the location of the component by application of ultraviolet laser radiation having an intensity sufficient to decompose and disperse said residual resin. This can be done without damaging the wiring on the board so that the wiring is re-usable to attach a further electronic component at the same location. Excessive heating of the board can be avoided by measures such as applying a pre-load to the component during softening so that it moves when sufficiently softened, and monitoring the softening.

Improved Zn-Ni-alloy-electroplated steel sheet can be prepared by electroplating steel sheet with an acid electroplating bath containing Zn ions, Ni ions and a small amount of titanium ions, preferably after pre-electroplating with an electroplating bath containing Zn ions and a larger amount of Ni ions and heating the plating sheet in the presence of water.
摘要:
A coloring agent which can be substantially completely decolored either through a treatment by a low concentration of chlorine type decoloring agents such as chlorine and hypochlorite or through a biological treatment usually employed in sewage treatments. The coloring agent is a certain group of polymethlyne compounds having at both the ends of the polymethyne chain pyrazolone structures. A composition comprising at least one of the coloring agents and additives in solution or solid form suitably used for coloring toilet bowl flushing water.
摘要:
A pull tab pivotally connected to a slider body is formed integral with a pair of locking cams which, when the pull tab is turned to a recumbent position on the slider body, intrude into the guide channel therein for pressing at least one fastener element into a depression formed in the inside surface of the bottom wing of the slider body and hence for locking the slider against movement. The depression is bounded at its front end by a pair of forwardly converging walls each formed at right angles with the plane of the slider body bottom wing and by a pair of rearwardly converging walls disposed between the forwardly converging walls and each inclined forwardly with respect to the plane of the slider body bottom wing.

A sputtering target contains high purity Nb of which Ta content is 3000 ppm or less and oxygen content is 200 ppm or less. Dispersion of the Ta content in all the sputtering target is within ±30% as a whole target. Dispersion of the oxygen content is within ±80% as a whole target. According to such sputtering target, an interconnection film of low resistivity can be realized. In addition, each grain of Nb in the sputtering target has a grain diameter in the range of 0.1 to 10 times an average grain diameter and ratios of grain sizes of adjacent grains are in the range of 0.1 to 10. According to such sputtering target, giant dust can be largely suppressed from occurring. The sputtering target is suitable for forming a Nb film as liner material of an Al interconnection.
