Abstract:
The invention includes improving or enhancing exchange coupling within a thin film layer. The improvement or enhancement to the exchange coupling occurs between the grains that are deposited to form the thin film. The improvement or enhancement to the exchange coupling between the grains of the thin film results from annealing the thin film at an elevated temperature for a period of time. A thin film structure and/or a magnetic recording layer made in accordance with the invention are disclosed.

Abstract:
The invention is an automatic heat-source shut-off system for cooking stoves. When a burner's flame is turned on, or an electric stove's heating element is turned on, the invention begins a timed sequence that upon expiring causes the heat-source control shaft to be returned to the heat-off position.

Abstract:
This invention relates to a refuse landfill leachate wastewater treatment system comprising a collection well, an adjustment tank, a filter, a comprehensive treatment system having a multi-stage anoxic/aerobic pool and a membrane biological reactor. The process of treatment is: waste water enters a adjustment tanke in which water quality and quantity are adjusted; subsequently, enters a filter, the water discharged from the filter and enters a comprehensive treatment system having a multi-stage anoxic/aerobic pool and a membrane biological reactor, wherein waster water is bio-chemically treated to remove the organic substances, nitrogen and ammonia, and then the wastewater is discharged into a catalyzed oxidation tower; the organic substance in waste water is oxidized on effect of ozone and under the existing catalyst function and then the biochemical capacity thereof is enhanced; and then the catalyzed and oxidized waste water enters carbon filter pool, the remaining contaminated matter can be further removed by degradation of the anoxic oxidation of the biological membrane on the packing material in pool, then the output water meets the requirement of National Standard or other relevant industrial standards.
Abstract:
A system and method for determining rotor speed of an AC induction machine is disclosed. The system is programmed to estimate a rotor speed of the induction machine according to a linear speed estimation algorithm and based on name plate information (NPI) of the induction machine and parameters of the AC induction machine during operation thereof. The rotor speed estimation system is also programmed to estimate a rotor speed of the AC induction machine according to a frequency-domain signal processing algorithm and determine if the rotor speed estimated thereby is valid. If the rotor speed estimated by the frequency-domain signal processing algorithm is valid, then a tuned rotor speed of the AC induction machine is estimated according to the linear speed estimation algorithm and based, in part, on the rotor speed estimated by the frequency-domain signal processing algorithm.

Abstract:
A system and method for determining the stator winding resistance of AC motors is provided. The system includes an AC motor drive having an input connectable to an AC source and an output connectable to an input terminal of an AC motor, a pulse width modulation (PWM) converter having switches therein to control current flow and terminal voltages in the AC motor, and a control system connected to the PWM converter. The control system generates a command signal to cause the PWM converter to control an output of the AC motor drive corresponding to an input to the AC motor, selectively generates a modified command signal to cause the PWM converter to inject a DC signal into the output of the AC motor drive, and determines a stator winding resistance of the AC motor based on the DC signal of at least one of the voltage and current.
