Abstract: The present invention relates to a PST-20 zeolite having a novel skeletal structure, its preparation method, and a selective separation and adsorption method for a gas using the PST-20 zeolite. More specifically, the present invention relates to a method of preparing a microporous aluminosilicate PST-20 zeolite having a novel skeletal structure totally different from the skeletal structure of known zeolites and using the PST-20 zeolite as an adsorbent/separator capable of selectively adsorbing/separating carbon dioxide to separate and collect carbon dioxide with high purity from burned gases or natural gases.

Abstract: Disclosed is an alerting device for an incoming call with an earphone jack of a portable mobile phone for notifying a user of an incoming call or an alarm from outside of the portable mobile phone. The alerting device of a portable mobile phone including an earphone jack for connecting an earphone with an earphone operator for operating the earphone includes an external incoming notifying device. The notifying system further includes a discriminator, an incoming notifying operator, a selector and a controller installed in the portable mobile phone. The external incoming notifying device includes at least one incoming notifying element, and an earphone jack connector for connecting the incoming notifying elements to the earphone jack. The discriminator, connected with the earphone jack, determines which device of the earphone and the external incoming notifying device is connected to the earphone jack. The incoming notifying operator operates the external incoming notifying device.
