A magneto-resistive device has a high reproducing output and is suitable for use as a CPP-GMR device. The magneto-resistive device has a first magnetic layer, a second magnetic layer, and a non-magnetic spacer formed between the first and second magnetic layers. The first magnetic layer contains a magnetic material whose conduction electrons belong to a first energy band, and the second magnetic layer contains a magnetic material whose conduction electrons belong to a second energy band. The first and second energy bands are attributable to orbitals of the same kind, thereby increasing the ratio of change in magnetoresistance and adjusting the electric resistance.

A thin film magnetic head includes a magneto-resistance (MR) laminated body, a lower shield layer and an upper shield layer that face the first MR magnetic layer. The lower and upper shield layers respectively have first and second exchange coupling magnetic field application layers and first and second antiferromagnetic layers. An exchange coupling intensity relating to an antiferromagnetic coupling between the second exchange coupling magnetic field application layer and the second antiferromagnetic layer is greater in the peripheral area of a projection area than that of the projection area of the upper shield layer side end surface of the MR laminated body to the film surface's orthogonal direction.

A lamp driving apparatus includes a change rate calculating section, a dimming transforming section and a power supplying section. The change rate calculating section calculates a change rate signal from an image signal corresponding to the image. The dimming transforming section outputs a digital dimming signal and an analog dimming signal, in response to a dimming signal provided from an external device and the change rate signal. The power supplying section provides the lamp with power, in response to a vertical synchronizing signal, the analog dimming signal and the digital dimming signal. Thus, although an instantaneous lamp current is increased, life and characteristics of the lamp will not be adversely influenced, and motion blur of a moving image may be removed.

The invention discloses a four-phase and double-salient brushless direct current motor with symmetrical phase inductances. According to the four-phase and double-salient brushless direct current motor, a unit motor is of a novel 12 / 9 salient structure or a novel 12 / 15 salient structure, each excitation element is wound after spanning three stator poles, each stator coil of each phase stator winding is distributed at different positions, and the symmetry of the phase inductances is achieved by a mode of symmetrically distributing the four phase stator windings; the pole-arc coefficient matching size of motor stators and rotors is determined by theoretical analysis and emulation verification methods, so that the phase inductances of the motor are hoisted and decreased by an electrical angle of 180 degrees, the total permeance of exciting windings remain basically unchanged, the positioning torque of the motor is small, and the four phases are electrified at the same time to operate. In addition, the four phase stator windings are independent in pairs, so that the motor can operate by only using the two phases after one phase is in fault, and the fault tolerance performance is favorable. Moreover, the total permeance of the exciting windings is unchangeable, so that the four-phase and double-salient brushless direct current motor has the advantages of small positioning torque and the like.

A method, apparatus and a system for thermally-assisted pulsed electromagnetic field stimulation for treatment of osteoarthritis are disclosed. In one embodiment, the system comprises a multi-coil applicator adapted for positioning near or around of the treated joint, a pulse generator functionally coupled to the applicator, a power supply, and a feedback loop for stabilizing the temperature of the joint. The feedback loop includes a heating element, a temperature sensor and an electronic controller for maintaining the temperature of the joint in the range of 38 to 42 degree C. At elevated temperatures the healing effect of PEMF stimulation on the cartilage is maximized and overall efficiency of the treatment is improved.

A receiver node includes an optical amplifier optically coupled to the input of a receiving device such as a PIN photodiode. A controller inputs received power level values from the receiver to perform gain control. The input signal of an optical receiving device, is pre-amplified by an optical amplifier such that the amplified signal is within a dynamic range of the receiving device. Upon the occurrence of a LOS (loss of signal) event, the controller sets the gain to a Home Gain value. Thus, when the signal is reestablished, a strong signal will not be over amplified and damage the receiver. Gain control is reestablished when the LOS event is over. Various methods are used to declare LOS including comparing the received power level or commanded pump power against a threshold. The LOS declaration may also be received from an external device or service channel.

Related apparatus, systems, techniques, and articles are also described.

An exchange coupling film including an antiferromagnetic layer and a ferromagnetic layer in contact with the antiferromagnetic layer so as to generate an exchange coupling magnetic field is provided. A PtMn alloy is used as the material of the antiferromagnetic layer. Crystal planes of the antiferromagnetic layer and the ferromagnetic layer preferentially aligned parallel to the interface are crystallographically identical and crystallographically identical axes lying in these crystal planes are oriented, at least partly, in different directions between the antiferromagnetic layer and the ferromagnetic layer. Thus, a proper order transformation occurs in the antiferromagnetic layer as a result of heat treatment and an increased exchange coupling magnetic field can be obtained.

A fast transient response converter is disclosed which makes use of stepping inductor in a switching converter to speed up output voltage response under fast transient condition. The inductive element in a switching converter is replaced by two series or parallel inductive elements, one of which has a smaller value of inductance than the other. During the fast transient period, the inductor with larger inductance value will be shorted to a voltage source. The total inductance will be greatly reduced and thus allows rapid current change during the transient change.
