The mask composition also contains at least one binder composition that binds with other beneficial ingredients by electrostatic, atomic, or ionic charges to synergistically enhance their topical site-specific benefits. These mask compositions are suitable for a variety of delivery system methods that include peel-off mask, leave-in mask, moisturizing mask, exfoliating mask, prosthetic mask, soaking mask, depilatory mask, foaming mask, rinse-off mask, sloughing mask, rub-off mask, two-phase mask, dual-chamber mask, and self-heating (heat releasing) mask.

An eye mask has magnetic bodies and self-heating warm members, which are inserted in eye pads on a mask member to be placed over eyeball parts. If required, vibrators and illumination bodies may be additionally placed in the eye pads. Thus, fatigue on the eyes and surroundings thereof can be relieved by the magnetic actions of the magnetic bodies and the warming effects of the warming member, in addition to expected effects of restoring ocular functions, recovering from various ocular diseases, and so on. Furthermore, the surface of each of the eye pads is gradually curved like the inner surface of a sphere. When the eye pads are press-contact to the eyeball parts at predetermined pressures for a long time, the cornea can be warmed by the warming members so that the shape of the cornea can be changed along the shape of the eye pad, resulting in the effects of recovering from eye sight disorder such as pseudo-myopia, moderate farsightedness, or moderate astigmatism.

Separate heating elements are embedded in a printed circuit board near integrated circuit (IC) packages or other parts mounted on the circuit board. Each heating element supplies heat to the part residing near it in response to an input voltage pulse. The heating elements are used to selectively melt solder or adhesives attaching the parts to the circuit board so that they can be easily removed or to temporarily melt solder or cure adhesive when the parts are mounted on the circuit board. The heating elements are also used to supply heat to IC packages for regulating their operating temperatures.

A self-heating or self-cooling container has a container body, a closure at one end of the body through which the contents of the container can be consumed, and a thermic module at the other end of the body having an actuator portion and an elongated reaction chamber portion that extends distally into the container body and contains a liquid reactant relatively more distally from the actuator portion than a solid reactant separated from the liquid reactant by a breakable barrier. When a user actuates the thermic module, an elongated actuator member punctures the barrier. The user can then immediately invert the container, allowing the liquid reactant to drain through the puncture into the solid reactant in the reaction chamber. The reactants mix and produce a reaction that, depending upon the reactants, either heats or cools the container contents by conduction through the thermic module wall. An advantage is that the user does not need to wait to invert the container after actuating it. Rather, the user can actuate the container, immediately invert it, wait until the contents reach the desired temperature, and consume the contents through the closure.

A battery self heating system for batteries that experience battery impedance or internal battery resistance when temperature drops. The system comprises an energy storage element applied to the battery terminals to draw energy from the battery. The energy is stored in a magnetic or capacitive storage device. The system is self-resonant so that energy transfer from the storage device to the battery will occur at a frequency and load level that is compatible with the current state of the battery. Internal heating of the battery is accomplished by a cycle comprising the out flux and influx of energy through the impedance of the battery. Energy losses due to battery impedance are converted to heat thereby heating the battery internally.

The invention relates to methods for manufacturing semiconductor devices. Processes are disclosed for implementing suspended single crystal silicon nano wires (NWs) using a combination of anisotropic and isotropic etches and spacer creation for sidewall protection. The core dimensions of the NWs are adjustable with the integration sequences: they can be triangular, rectangular, quasi-circular, or an alternative polygonal shape. Depending on the length of the NWs, going from the sub-micron to millimeter range, the NWs may utilize support from anchors to the side, during certain processing steps. By changing the lithographic dimensions of the anchors compared to the NWs, the anchors may be reduced or eliminated during processing. The method covers, among other things, the integration of Gate-All-Around NW (GAA-NW) MOSFETs on a bulk semiconductor. The GAA structure may consist of a silicon core fabricated as specified in the invention, surrounded by any usable gate dielectric, and finally by a gate material, such as polysilicon or metal. The source and drain of the GAA-NW may be connected to the bulk semiconductor to avoid self heating of the device over a wide range of operating conditions. The GAA-NW MOS capacitor can also be used for the integration of a Gate-All-Around optical phase modulator (GAA modulator). The working principle for the optical modulator is modulation of the refractive index by free carrier accumulation or inversion in a MOS capacitive structure, which changes the phase of the propagating light.
