A reader of a magnetoresistive head includes a spin valve with sensor having a stabilizing hard bias and side shield at the side of the sensor, to substantially reduce the undesired flux from adjacent bits and tracks. At least one free layer is spaced apart from at least one pinned layer by a spacer. Above the free layer, a capping layer is provided. The stabilizer may include an insulator, a soft material that is a shielding layer, a decoupling layer, and a hard bias. As a result, the free layer is shielded from the undesired flux of adjacent tracks, and recording media having substantially smaller track size and bit size can be used.

The invention discloses a power stabilizer of integrated wind power that is based on active voltage source direct current power transmission and belongs to the technical field of power network power stabilizer. The invention is a device that is used for stabilizing the power of integrated wind power and is based on active voltage source direct current power transmission, and the stabilizer comprises a rectifier, an inverter, an energy storage device, a DC bus and a controller. In steady-state operation, the voltage source direct current power transmission transmits wind power to power networks, and at the same time compensates the dynamic fluctuation of the wind power through the energy storage device that is connected in parallel on the voltage source DC bus, so that the power of the wind power that is input into the power networks through the voltage source direct current power transmission is stable. When the power networks are in fault, the active power and the reactive power that are input into the power networks are adjusted, and the steady operation performance of the power networks is enhanced. The device solves the problem that the dynamic fluctuation of wind power is influenced by input power networks, improves greatly the stabilization of integrated wind power and bears great significance in the energetic development of wind power generation.

The invention discloses a stability method for a power system and a stabilizer thereof. Filtering, eliminating direct current component, phase compensation and volt-limiting processing are carried out in sequence; wherein, the transfer function of the phase compensation is determined according to the following steps: 1 obtaining the phase characteristic Phi of a dynamo; 2. calculating the phase compensation characteristic Phi according to the engaged compensation requirement Phi<0> and the phase characteristic Phi; 3. taking the phase compensation characteristic Phi as a target curve to carry out curve fitting, obtaining a phase compensation curve f(x) which approaches the target curve and determining the transfer function of the phase compensation according to the phase compensation curve f(x). The stabilizer comprises a filter, a redactor a phase compensator and a volt-limiting device connected in sequence. The invention can well approach the needed compensation curve by adopting the transfer function of the phase compensation, thus carrying out better compensation for a lagging phase of the dynamo in the whole oscillation range with low frequency.

An improved packaged liquid crystal display (LCD) assembly is described. A recess is used to house a support material while the LCD cell 609 is positioned at least partially within the containment structure. A plurality of spaced apart stabilizers are attached from the sides of the LCD cell 609 to the substrate without transmitting residual stresses induced during fabrication and operation. A support material is dispensed in the recess such that it provides support for the LCD cell 609 without transmitting residual stresses from the substrate. The described arrangements permit an LCD assembly which minimizes the amount of forces and stresses that lead to optical defects. The stabilizers, in addition to supporting the cell, also act to contain the encapsulating material used to protect the bonding wires. The support material, in addition to minimizing transmission of stresses, also provides improved heat dissipation from the LCD cell 609. In another embodiment, a method for constructing the LCD assembly is described.

A high-voltage discharge lamp lighting apparatus has a stabilizer 12 which supplies a power voltage used for maintaining the lighting operation to a high-voltage discharge lamp 20, and an ignitor circuit having an oscillating circuit-for-driving 13 in which a start pulse generates upon starting the lighting operation of the high-voltage discharge lamp, and high-voltage pulse generating transformers (14a, 14b, and 14c) which increase a voltage of the start pulse. Further, the high-voltage discharge lamp lighting apparatus includes a cap portion 16 to which the high-voltage discharge lamp 20 is attached and held, including a part of the high-voltage pulse generating transformers of the ignitor circuit, and a socket portion 11 to which the cap portion 16 is attached and is fit, including at least the oscillating circuit-for-driving 13 in the ignitor circuit and a portion of the high-voltage pulse generating transformers except for a part included in the cap portion 16. A primary coil 14a, a secondary coil 14b, and a magnetic coil 14c of the high-voltage pulse generating transformers are dividedly accommodated and arranged in the cap portion 16 and the socket portion 11. Thus, the continuous generation of a high voltage is prevented at connecting pieces of the portions upon detaching the cap portion 16 from the socket portion 11, the electric shock of an operator is prevented, and costs are reduced upon replacing the lamp.
