Abstract:
A disposable life-saving garment for use in the event of fire, comprises a body-protecting portion and a head-protecting portion. The body-protecting portion is configured with a lining formed to enclose the body of a wearer and a cover covering the liner, the cover being made of a sealed material that can block the passage of air. A closed air passage is formed between the liner and cover. A compressed air tank is installed in a pocket of the cover and is connected to the air passage through a check valve. An intake hose supplies compressed air from the air passage of the body-protecting portion to the head-protecting portion. The head-protecting portion has a heat-resistant transparent window and a one-way outlet unit. The body-protecting portion and the head-protecting portion are made of a nonflammable material or a fire retardant material.
Abstract:
Methods of forming gates of semiconductor devices are provided. The methods may include forming a first recess in a first substrate region having a first conductivity type and forming a second recess in a second substrate region having a second conductivity type. The methods may also include forming a high-k layer in the first and second recesses. The methods may further include providing a first metal on the high-k layer in the first and second substrate regions, the first metal being provided within the second recess. The methods may additionally include removing at least portions of the first metal from the second recess while protecting materials within the first recess from removal. The methods may also include, after removing at least portions of the first metal from the second recess, providing a second metal within the second recess.

Abstract:
A three-terminal Ovonic Threshold Switch (OTS) is used to provide current to a Phase Change Memory Switch (PCMS) cross point array. The current is started by sending a small current into the second terminal of the three-terminal OTS allowing a larger current to flow from the first terminal to the third terminal of the three-terminal OTS. A method of making the three-terminal OTS is also presented.
