摘要:
A phase-change memory cell having a reduced electrode-chalcogenide interface resistance and a method for making the phase-change memory cell are disclosed: An interface layer is formed between an electrode layer and a chalcogenide layer that and provides a reduced resistance between the chalcogenide-based phase-change memory layer and the electrode layer. Exemplary embodiments provide that the interface layer comprises a tungsten carbide, a molybdenum carbide, a tungsten boride, or a molybdenum boride, or a combination thereof. In one exemplary embodiment, the interface layer comprises a thickness of between about 1 nm and about 10 nm.

Devices include multiple phase change materials connected in parallel between electrodes. Memory cells with multiple parallel phase change materials can be programmed to transition among more than two states representing multiple bits of information. Methods for manufacture and use are also disclosed
摘要:
A fluid sealing device for rotating machines having a rotor part including at least one disk carried by a rotating shaft rotating in and relatively to a stator part in the presence of a fluid is disclosed. The rotating shaft has a sealing system defining a first environment at a first pressure. The stator part has a wall in front of the disk of the stator part defining a second environment therewith containing a fluid at a second pressure. The device includes a movable ring placed between the wall of the stator part and the disk of the rotor part and has a front sealing gasket facing towards the disk. The movable ring is moved in the active position when the rotating machine is stopped to prevent the fluid passage from one environment to the other.

The power P of the heater of a dryer is regulated in order to heat up the air used to dry washed articles placed in the drying chamber to a temperature close to a set point temperature TSET. The output signal of the regulator of the heater is used to estimate the moisture content of the fabrics and to terminate the drying cycle when a predefined moisture level is reached.

摘要:
A method for controlling the operation of a clothes dryer having a drying chamber and an air flow system including a variable speed blower for forcing air through the drying chamber comprises the step of assessing a value related to the water removal rate and the step of adjusting the speed of the blower depending on the assessed value, the value being preferably based on a ratio between the water condensing rate and the power of a heater used to heat up the air flow upstream the drying chamber.
