Abstract

The present invention relates to an oxygen supply elevator (100) which supplies oxygen to the internal space of the elevator or to a separate oxygen mask arranged in the elevator to enable people in the elevator to easily breath and remove smog or the like. The oxygen supply elevator (100) comprises an oxygen containing unit (10) arranged in a facility mounting space (S2) formed in an upper portion of the elevator and containing oxygen having a pressure higher than the atmospheric pressure; an oxygen supply unit (20) connected to the oxygen containing unit (10) through at least one communication channel (30) so as to supply oxygen to an oxygen supply space (S1) formed in the elevator; a valve unit (40) arranged on the communication channel (30) so as to adjust the flow rate of the oxygen discharged from the oxygen containing unit (10); and a control unit (50) connected to the valve unit (40) so as to determine whether to open/close the valve unit (40) or adjust the degree of opening/closure of the valve unit (40).

Abstract

The present invention relates to a portable oxygen respirator which is effective at preventing difficulty in breathing or preventing suffocation when a fire breaks out or a poisonous gas is discharged. The portable oxygen respirator includes: a first body (110) supplying high pressure oxygen having a pressure greater than that of air; and a second body (120) detachably coupled to the first body (110). When the first body (110) and the second body (120) are coupled together, an integrated outer shape of combined surfaces is formed.

Abstract

The present invention relates to a decompressor for a compressed-gas container, wherein the may adjust the amount of gas being discharged, while discharging the compressed-gas stored in the container in a timely and easy manner, and also may discharge overly pressurized gas to the outside via a safety device arranged at one side of the decompressor when the gas is exposed to a high temperature or is highly pressurized by a flame or the like during storage or use, thus preventing the explosion of the container. The decompressor of the present invention comprises: a main body made of a metal; a spindle slider which slides by means of the elastic force of a spring; and an operating lever which melts at a low temperature. The decompressor of the present invention may be provided as a sliding-type or punching-type decompressor.

Abstract

The present invention relates to a soft electrode material which includes an electrode layer that contains a mixture having at least one of the following: carbon black, carbon nanotube, or graphene, wherein various physical transformations, such as bending, extending, and the like of the electrodes, are made convenient, the flexibility and the elasticity are maintained in such transformations, sudden degradation of the electric conductivity of the electrodes are prevented, and displays excellent reliability. Therefore, the electric-mechanical energy transformation efficiency of soft electronic parts such as actuators that contain the present invention increases and at the same time, the electric conductivity of the electrode layer is also enhanced as the electric-mechanical energy transformation efficiency increases.
