Abstract: A gradual fiber cladding light stripper and its manufacturing method is disclosed to include an optical fiber that has a core, a cladding outside the core and an outer coating outside the cladding, the outer coating being removed by a preset cutting fixture to form a pre-stripping section, and a recoating section coated on the surface of the pre-stripping section at one time with a covering glue, the covering glue being irradiated and cured through a preset light curing device to form the recoating section with a gradual light stripping rate. The recoating section has a laser light input terminal with a relatively lower light stripping rate, and a laser light output terminal with a relatively higher light stripping rate.

Abstract: A press switch shower faucet, that includes: a main body, on which is disposed a hot water inlet hole and a cold water inlet hole; and a valve cartridge, disposed inside the main body, on the valve cartridge is disposed a rotation switch for adjusting temperature, and a press switch for controlling open/close of a water channel. Through the design of the press switch shower faucet, the water temperature adjusting function and the water open/close function can be carried out independently, so that in the next time the user utilizes water, he may use the water directly without the need of adjusting water temperature, in achieving great convenience and satisfaction for the user.

Abstract: A multi-function pull head comprises a valve seat, and that includes: a water input connector, an outer shell, a water output portion, a first function switching structure, a second function switching structure, and a water output panel. The water input connector is connected onto the outer shell through a thread structure, and two through holes are provided on the outer shell, for the first function switching structure and second function switching structure to pass through respectively. The water input connector is disposed on a top portion of the valve seat. The outer shell is disposed on a bottom portion of the water input connector, to protect the valve seat. The outer shell is engaged to the water input connector through an engaging ring. The water output portion is disposed at a lower portion of the valve seat.

Abstract: The inventive catalyst composition is a sponge metal catalyst comprising at least one skeletal porous sponge metal selected from the group consisting of nickel, cobalt, iron and copper, together with a first promoter metal selected from the group consisting of palladium, platinum, ruthenium, rhodium, osmium and iridium and a second promoter metal selected from the group consisting of iron, nickel, cobalt, zinc, vanadium, cerium, copper, tungsten, molybdenum, titanium, niobium, manganese, silver, cadmium, praseodymium and neodymium. Processes for the manufacture of the catalyst include impregnation or precipitation of the promoter metals onto the sponge metal catalyst.
