摘要： In one embodiment, a magnetic head includes a magnetoresistive free layer, wherein a width of the free layer nearest an air bearing surface (ABS) is less than a width of the free layer at a point away from the ABS in a track width direction, with the magnetic head being configured to pass a sense current in a direction perpendicular to a plane of deposition of the free layer. In another embodiment, a method includes forming a magnetoresistive film above a shield, forming a masking layer above the magnetoresistive film, patterning the masking layer such that it exposes portions of the magnetoresistive film, wherein the masking layer defines an area which is narrow near an area that forms an ABS side of a free layer and wider at an area away from the ABS, and removing the exposed portions of the magnetoresistive film to form the free layer.

摘要： A magnetic sensor having reduced read gap thickness, reduced signal noise and improved signal to noise ratio. The sensor includes a sensor stack and hard bias structures formed at either side of the sensor stack for biasing the free layer of the sensor. A protective layer is formed over a portion of the hard bias structure, however a portion of the hard bias structure extends upward toward the upper shield and is disposed between the protective layer and the sensor stack as a result of the process used to form the magnetic bias structure. This portion of the hard bias structure that extends toward the upper shield has a reduced magnetization relative to the rest of the hard bias structure so that it will not magnetically couple with the upper shield.

摘要： A regenerative heat exchange system performs heat exchange by alternately passing combustion exhaust gas as high-temperature fluid and combustion air as low-temperature fluid through a fixed regenerator. A regenerative burner carries out combustion using preheated air from the exchange system. The regenerative heat system comprises: a permeable regenerator partitioned into three or more chambers in the circumferential direction; a double-pipe outlet/inlet partitioned into a supply chamber and an exhaust chamber; and changeover member which isolates the regenerator from the outlet/inlet and by which the regenerator selectively communicates with the outlet/inlet by a supply communicating hole and an exhaust communicating hole which are provided with such a positional relation that the supply communicating hole and the exhaust communicating hole do not simultaneously lie in any of the partitioned chambers.

摘要： A heating apparatus for heating supply of gaseous fluid 1 heats a relatively low temperature gaseous fluid and feeds a heated supply flow to a high temperature gaseous fluid introduction equipment. The heating apparatus has heat exchangers 11, 12 provided with fluid passages through which the low temperature fluid flow passes, a splitting area 15 for dividing a heated supply flow H of gaseous fluid, which is heated by the heat exchanger, into first and second heated gaseous streams H1, H2, and combustion areas 13, 14 in which a combustion reaction of combustible matter takes place in the existence of the first heated gaseous stream. The heated supply flow or the first stream is introduced into the combustion area and the combustible matter is fed thereto, and the combustion area causes the combustion reaction of combustible matter in the existence of the heated supply flow or the first stream. Hot gas produced by the combustion reaction is exhausted through the heat exchanger. The heat exchanger has a regenerator which accumulates heat in its heat-transferable contact with the hot gas and emits the heat in its heat-transferable contact with the low temperature gaseous fluid. The heating apparatus heats or preheats the low temperature gaseous fluid to a high temperature and feeds the second heated gaseous stream to the equipment.

摘要： An automobile steering rack manufacturing apparatus has a material clamp for holding a hollow pipe-like rack material that has a solid core bar inserted therein. A forming roll on the apparatus has an outer periphery with rack teeth formed thereon, while a material drive causes a mutual rolling of the material clamp and the forming roll, thereby cutting rack teeth into the material. The clamp moves in the tangential direction of the forming roll orientation, and a tooth depth controller controls the distance between the rack material held in the material clamp, and the forming roll.

摘要： A gasifying apparatus comprises a gasifier, a reformer and a heating device. The gasifier produces a thermal decomposed gas with use of a thermal decomposition reaction of a liquid or solid fuel such as waste or coal, and the heating device heats a low-temperature steam and air so as to be a high-temperature steam and air, which have a temperature equal to or higher than 700 deg. C. The gasifying apparatus has feeding means including fluid passages for feeding the high-temperature steam and air to the gasifier and the reformer. In a thermal decomposition area of the gasifier, the liquid or solid fuel is thermally decomposed to produce the thermal decomposed gas with sensible heat of the high-temperature steam and air and with the heat generated by an exothermic oxidation reaction between the high-temperature air and the liquid or solid fuel. In the reformer, the thermal decomposed gas is reformed in the existence of the high-temperature steam so as to be a high-temperature syngas. The steam reforming reaction of the liquid or solid fuel is carried out with an exothermic reaction between the high-temperature air and hydrocarbon contained in the thermal decomposed gas and with an endothermic reaction between the hydrocarbon and the high-temperature steam.
