Abstract: PURPOSE: A method of operating storage cell arrangement is provided to achieved a time of at least 150 years for the data preservation and whereby digital information stored in the memory cell arrangement can be electrically modified. CONSTITUTION: The invention concerns a method of operating a storage cell arrangement having MOS transistors as storage cells which comprise, as gate dielectric, a triple dielectric layer (5) consisting of a first silicon oxide layer (51), a silicon nitride layer (52) and a second silicon oxide layer (53), each of the silicon oxide layers being at least 3 nm thick. According to the invention, in order to store digital data, a first threshold voltage value of the MOS transistor is allocated to a first logic value and a second threshold voltage value of the MOS transistor is allocated to a second logic value. The data stored in the storage cell can be altered by applying corresponding voltage levels, although complete removal of the charge stored in the silicon nitride layer is prevented by the thickness of the silicon oxide layers. The threshold voltage variation makes use of the fact that the electrical field in the triple dielectric layer is distorted by the charge stored in the silicon nitride layer.

Title: Expansion valve of air conditioner system for automobile
Inventor: OH MAN JU
IPC: F25B41/06

Abstract: A system for carrying out transactions (10) includes customer stations (18) and a service provider station (14). The system is operated in a building (12) or other facility in which a service provider operates the service provider station in a secure room (36). Audio and video communications are established between customers at the customer stations and the service provider at the service provider station. Items are exchanged between customers and the service provider through carriers (26) transmitted through a pneumatic tube system (22). A video material presentation device (50) provides promotional or other video material which is presented on displays at the customer stations. Video material is presented to customers when the customer terminal is not in communication with the service provider terminal. The customer stations are readily installed and configured in the transaction facility to maximize the floor space available for other purposes.
