A pressure wave generator is provided, which has excellent output stability over time. This pressure wave generator comprises a substrate, a heat generating layer, and a heat insulating layer formed between the substrate and the heat generating layer. A pressure wave is generated in a surrounding medium (air) by a change in temperature of the heat generating layer, which is caused upon energization of the heat generating layer. The heat insulating layer comprises a porous layer and a barrier layer formed between the porous layer and the heat generating layer to prevent diffusion of reactive substances such as oxygen and moisture in the air and impurities into the porous layer. By the formation of the barrier layer, it is possible to prevent a reduction in output of the pressure wave generator caused by a change over time of the porous layer.

A phototherapy light cap is a flexible, generally hemispherical cap having a light source to supply suitable dosage requirements of current and future light therapies. The phototherapy light cap may also include a rechargeable battery source, a light source or an array of light sources, a light diffuser and an interface to a recharging source that may be a docking station. A phototherapy light cap may alternatively be an insert for any commercial head dressing, preferably adapted for convenient recharging. Combining the use of a phototherapy light cap with gelatinized therapeutic agents provides a suitable treatment technique for a scalp utilizing phototherapy, heat and any suitable combination of active ingredients such as minoxidil.

The antenna comprises a transmission line having an inner conductor, an outer conductor, and a dielectric insulator to provide insulation between the inner and outer conductors. An energy emitting antenna element is located at the distal end of the transmission line. The antenna element has an inner conductor which is electrically coupled to the inner conductor of the transmission line, and, around the inner conductor, a sheath of dielectric insulator continuous with the insulator of the transmission line. At its distal end, a hollow metallic cap is electrically connected to the inner conductor, surrounding a length of the insulator.

A motor vehicle dehumidifier, including a dehumidifying drying agent, that can provide a required dehumidifying capacity with a reduced overall quantity of drying agent compared to conventional drying agent-based dehumidifiers. In the present invention, a heat exchanger is disposed on an upstream side of a drying agent unit, and heat is exchanged in the heat exchanger between inside air to be dehumidified and low-temperature outside air used to cool the inside air. The air cooled by the heat exchanger flows into the drying agent unit and is dehumidified. Because the air has an increased relative humidity as a result of being cooled, the amount of water adsorbed from it per unit of drying agent is increased, as the water adsorption characteristic of the drying agent is greatly influenced by the relative humidity of the air passing over it, and is markedly improved by an increase in the relative humidity of that air.

A well treating composition containing a polysaccharide-based water-superabsorbent material has particularly applicability as a thermal insulating, fracturing or acid stimulation fluid. The water-superabsorbent material is capable of absorbing, at a minimum, its own weight. Particularly effective are biodegradable materials containing guar gum and carrageenan. The composition may further contain a crosslinking agent, brine and/or a viscosifying polymer or a gelling agent. As an oil-based fluid, the crosslinking agent is absorbed onto the water-superabsorbent material and serves to effectively delay crosslinking.

The heat conductor includes a heat radiator exposed outside of the translucent member.

A hair curling iron that forms spiral curls having an integral vacuum system and an internal heating tube is designed to eliminate the need for manual rotation of the entire curling iron when forming spiral hair curls. The curling iron provides a slot into which the hair is pulled by an integral vacuum fan mounted within the handle and controlled by an on/off pushbutton. When activated, the vacuum fan pulls the hair into the curling iron and around an interior heating tube. After several seconds, the pushbutton is released and a spiral curl is pulled out of the curling iron. A separate illuminating switch provides control of the heating portion of the curling iron. The danger of accidental burns is greatly reduced due to the interior location of the hot surfaces.
