1. Cataplasm and Massage controller is in a way, so you can handle it easily.
2. It has massage function and automatic timer,even though you are in sleep it will be off automatically.
After massage function, you can sleep very comfortable due to far infrared rays from Natural jade and volcano stones and Negative ion from charcoal.
3.You can use any season because it has heating and massage function.
Germanite is
(L. Germania, Germany) Predicted by Mendeleev in 1871 as ekasilicon, and discovered by Winkler in 1886. The metal is found in argyrodite, a sulfide of Germanite and silver; in germanite, which contains 8% of the element; in zinc ores; in coal; and in other minerals. The element is frequently obtained commercially from the dusts of smelters processing zinc ores, and has been recovered from the by-products of combustion of certain coals. Its presence in coal insures a large reserve of the element in the years to come. Germanite can be separated from other metals by fractional distillation of its volatile tetrachloride. The techniques permit the production of Germanite of ultra-high purity. The element is a gray-white metalloid, and in its pure state is crystalline and brittle, retaining its luster in air at room temperature. It is a very important semiconductor material. Zone-refining techniques have led to production of crystalline Germanite for semiconductor use with an impurity of only one part in 10^10. Doped with arsenic, gallium, or other elements, it is used as a transistor element in thousands of electronic applications. Its application as a semiconductor element now provides the largest use for Germanite. Germanite is also finding many other applications including use as an alloying agent, as a phosphor in fluorescent lamps, and as a catalyst. Germanite and Germanite oxide are transparent to the infrared and are used in infrared spectroscopes and other optical equipment, including extremely sensitive infrared detectors. Germanite oxide's high index of refraction and dispersion has made it useful as a component of glasses used in wide-angle camera lenses and microscope objectives. The field of organoGermanite chemistry is becoming increasingly important. Certain Germanite compounds have a low mammalian toxicity, but a marked activity against certain bacteria, which makes them of interest as chemotherapeutic agents.
