A flexible diffuser membrane is provided with a unique system of perforations arranged to result in uniform distribution of gas even though the membrane deflects to different extents or the submergence varies in different parts of the membrane. The perforations are arranged to provide less perforation area per unit of perforated membrane surface area in the membrane parts that deflect the most or are submerged least and greater perforation area in membrane parts that deflect the least or are submerged most. The perforations can be slits arranged in parallel rows on a tubular membrane, in concentric circles or another pattern on a disk membrane, or in still a different pattern on a flat panel diffuser membrane. The slit length or separation can be varied between different zones on the membrane surface or the spacing between rows or circles can be varied.

A method for manufacturing an ultrafine carbon fiber of the present invention has several steps as follows. In the first step, a semiconductor film is formed over a surface having insulative. In the second step, a first treatment is performed so that a metal element or a silicide of the metal element is segregated on a crystal grain boundary of the semiconductor film after adding the metal element in the semiconductor film. In the third step, a second treatment is performed so that an ultrafine carbon fiber on the surface of the metal element or the silicide of the metal element is formed.

A slim-type air conditioner is provided. The slim-type air conditioner blows air by a plate reciprocating back and forth. Accordingly, the air can be discharged through a wide outlet hole, and the size and thickness of the air conditioner can be reduced. Therefore, the convenience of users and installers can be improved.

A hair setting device comprises a setting material supply for storing hair setting material, a hollow pipe-shaped body including a guide groove formed along a lengthwise direction of the body and a slit formed at a bottom of the guide groove, the slit communicating with an inside space of the hollow pipe-shaped body, a base for fixing the hollow pipe-shaped body to the setting material supply, the base communicating with the inside space of the hollow pipe-shaped body and including an inner surface enclosing a nozzle of the setting material supply, an operating valve, including a setting material guide hole at a center portion of the operating valve, the operating valve being supported by a first spring inside the hollow pipe-shaped body, a bottom end portion of the operating valve being in contact with the nozzle of the setting material supply, a push button installed at a bottom portion of the hollow pipe-shape body in a radial direction thereof and supported by a second spring, wherein the push button is in contact with the operating valve in such a way that the operating valve is moved toward the nozzle of the setting material supply when the push button is pressed, and a comb including a base portion which is detachably engaged with the guide groove of the body and a plurality of outlets arranged in a regular interval for allowing the hair setting material to come out from the slit.

The present invention provides a metal hydride canister apparatus having structures capable of discharging hydrogen gas uniformly and exchanging heat effectively, comprising: a shell having a joint arranged in a central hole located on top of the shell, and two via holes arranged respectively at a side of the central hole; a filtering rod connecting to the joint; a pipe having a first end, a second end and a middle section between the first end and the second end; and a metal hydride stored inside the shell; wherein, the first end and the second end of the pipe pass the corresponding via hole in respective, and the middle section of the pipe forms a twin spiral structure wrapping around the filtering rod, the middle section having a first loop interconnecting to a second loop. In a preferred embodiment of the present invention, the filtering rod can be a hollow rod extending toward the bottom of the shell, and is welded on the joint that is further welded to the central hole, in addition, the first end and the second end of the pipe are welded onto the corresponding via holes and are exposed to the outside of the shell, and the first loop and the second loop of the middle section can have equal diameters or different diameters.
