A hair dryer includes a motor and a fan to generate an air current within a housing, and a heater for selectively supplying heat into air introduced from the outside of the housing by the fan. A discharge nozzle is disposed on one end of the housing. A coanda surface is disposed on the discharge nozzle. Thus, the air passing through the housing flows along the coanda surface to suction air outside the discharge nozzle into a central passage part of the discharge nozzle, thereby mixing the suctioned air with the air passing through the housing. The air mixed within the central passage part is discharged through a discharge hole of the discharge nozzle. Since the air passing on the coanda surface suctions the air outside the discharge nozzle, the motor may be reduced in capacity. Also, an electromagnetic shielding effect may be significantly improved.

A mask main body and wearing band, wherein the mask main body includes an adhering piece formed at an inside edge of main body. A fixed frame forms an exhaust space at an inner center. Multiple exhaust holes are formed on both ends of exhaust space. The exhaust panel is inserted in and fixed with fixed frame, having multiple discharge holes. Multiple shield films are formed on the front side of discharge holes and opened at exhalation. A filter cover is formed on both sides of mask main body as a single body. A removable and replaceable filter case is combined with the filter cover. A dustproof nonwoven fabric, carbon filter, antibiotic nano-silver filter, dustproof nonwoven fabric are included in the filter case.

An optical subassembly includes a high speed ceramic substrate having cavity containing an array of photodetectors, and a glass or silicon window for covering the cavity and forming a hermetic seal. A retainer is attached to the window for direct or indirect attachment to a fiber. The hermetic seal protects the device from moisture and other environmental conditions. The window has an index of refraction higher than air that effectively increases the optical pathlength sufficient while maintaining an acceptable coupling efficiency between the optoelectronic device and a fiber. This provides increased spacing within which to place and interconnect components within the cavity on the substrate. In alternate embodiments, the window is decoupled from direct contact with the retainer via a metal frame or ring. Decoupling the window from direct contact with the retainer helps prevent cracking of the window due to mismatches in the coefficients of thermal expansion between the window and the retainer.

A coaxial connector for attaching the end of a coaxial cable to an equipment port includes a tubular post, a coupler, a body member having a cylindrical sleeve, and one or more reservoirs containing a chemical component disposed between the post and the cylindrical sleeve. Insertion of the coaxial cable into the connector opens the reservoir, releases the chemical component, and secures the jacket of the cable within the cylindrical sleeve. The chemical component(s) can include an adhesive, a volume-expanding material, and / or an agent that swells the jacket of the cable. Two or more chemical components may be stored in two or more adjacent reservoirs.

A bank layer includes projecting portions swollen toward in a thickness direction of a first substrate in an adhesion area. A multi-barrier includes a portion, in which a organic barrier is not disposed, on an upper side of the projecting portions. Therefore, it is possible to obtain, in the adhesion area, a portion in which a first inorganic barrier layer and a second inorganic barrier layer directly come in contact with each other. In an organic EL display device including the multi-barrier formed of an organic material and an inorganic material, it is possible to prevent two facing substrates from being separated from each other.

A semiconductor display device with an interlayer insulating film in which surface levelness is ensured with a limited film formation time, heat treatment for removing moisture does not take long, and moisture in the interlayer insulating film is prevented from escaping into a film or electrode adjacent to the interlayer insulating film. A TFT is formed and then a nitrogen-containing inorganic insulating film that transmits less moisture compared to organic resin film is formed so as to cover the TFT. Next, organic resin including photosensitive acrylic resin is applied and an opening is formed by partially exposing the organic resin film to light. The organic resin film where the opening is formed, is then covered with a nitrogen-containing inorganic insulating film which transmits less moisture than organic resin film does. Thereafter, the gate insulating film and the two layers of the nitrogen-containing inorganic insulating films are partially etched away in the opening of the organic resin film to expose the active layer of the TFT.

To provide a light emitting device that has a structure in which a light emitting element is sandwiched by two substrates to prevent moisture from penetrating into the light emitting element, and a method for manufacturing thereof. In addition, a gap between the two substrates can be controlled precisely. In the light emitting device according to the present invention, an airtight space surrounded by a sealing material with a closed pattern is kept under reduced pressure by attaching the pair of substrates under reduced pressure. A columnar or wall-shaped structure is formed between light emitting regions inside of the sealing material, in a region overlapping with the sealing material, or in a region outside of the sealing material so that the gap between the pair of substrates can be maintained precisely.

In order to provide a display device of high reliability in which an amount of moisture and oxygen, which are a factor for deteriorating a characteristics of a display device, entering from a sealing agent is reduced and its manufacturing method, the present invention has a sealing film. Accordingly, an interlayer insulating film including an organic material of the display device (panel) is no longer exposed to the atmosphere outside of the display device. Therefore, it becomes possible to prevent moisture and oxygen outside of the display device from entering inside of the display device through an insulating film and the like including a hygroscopic organic material. In addition, various degradations such as contamination of an inner part of the display device caused by moisture, oxygen and the like, the degradation of electric properties, a dark spot and shrink can be prevented, thus enhancing reliability of the display device.
