摘要:
First and second magnetic layers of a magnetic head face each other. A toroidal coil layer having upper and lower layer coil pieces (ULCP and LLCP) is wound around one of the magnetic layers. The ULCP extend from a first insulating layer by downward steps to a top of a second insulating layer which is widened at ends of the first insulating layer. Side ends of the first insulating layer extend parallel to a height direction. The ULCP are orthogonal to the side ends. Each of the LLCP is formed on a third insulating layer and has a straight region extending in the same direction as the upper layer coil pieces and a curved region curved toward a facing surface or in a height direction on one end in the track width direction. An end of each of the straight and curved region is connected to an ULCP.

An ECT-ECU includes an abrupt turbine speed increase learning control circuit which prevents simultaneous release of both a frictional engagement element to be released and a frictional engagement element to be engaged, a tie-up learning control circuit which prevents simultaneous engagement of both the frictional engagement element to be released and the frictional engagement element to be engaged, a determination circuit that determines whether one of tie-up learning control and abrupt turbine speed increase learning control is necessary based on the turbine speed, and a control circuit that prohibits execution of the tie-up learning control unless the number of trips after the abrupt turbine speed increase learning control has been executed is at least equal to a predetermined number, when it has been determined that the tie-up learning control is necessary.
摘要:
In a thin film magnetic head, a face surface faces a recording medium and a front surface of an upper core layer is a curved surface which gradually retreats in a height direction generally perpendicular to the face surface as it approaches both sides thereof, and the thickness of the upper core layer gradually increases in the height direction. It is thus possible to appropriately suppress the occurrence of side fringing, efficiently cause a magnetic flux to flow from the upper core layer to an upper pole layer, and make the thin film magnetic head adaptable to a higher recording density.

A thin-film magnetic head includes a lower core layer, a gap layer, an upper pole layer, and an upper core layer. At the joint between the upper pole layer and the upper core layer, the width of the upper core layer is larger than the width of the upper pole layer, and also the inner end of the upper core layer is located at the back of the inner end of the upper pole layer. Alternatively, a thin-film magnetic head includes a lower core layer, a recording core, an upper core layer, a coil, and a magnetic intermediate layer. The magnetic intermediate layer has a higher saturation flux density than that of the upper core layer. Methods for fabricating thin-film magnetic heads are also disclosed.

A thin-film magnetic head includes a first coil layer disposed at a lower core layer side of the interface between an upper core layer and an upper magnetic-pole layer, which are joined to each other, and a second coil layer disposed at the upper core layer side of the interface between the upper core layer and the upper magnetic-pole layer. The thickness of a coil conductor of the first coil layer is set smaller than the thickness of a coil conductor of the second coil layer.

In an air conditioner including an indoor heat exchanger and an indoor fan which are disposed in an indoor-side chamber, and an outdoor heat exchanger and an outdoor fan which are disposed in an outdoor-side chamber, the indoor-side chamber and the outdoor-side chamber being partitioned by a partition plate mounted on a bottom plate, the outdoor heat exchanger is disposed on said bottom plate, and the bottom plate is integrally formed with a dam member for damming up drain water flowing from at least one of the indoor heat exchanger and the outdoor heat exchanger. Further, a drain pan on which the indoor heat exchanger is mounted is disposed on the bottom plate, the partition plate is equipped with a drain opening through which drain water flowing from the indoor heat exchanger through the drain pan is flows to the bottom plate, and at least one of the drain pan and the partition plate is equipped with an intercepting member for intercepting flow of rain/wind from the outdoor-side chamber to the indoor-side chamber.
摘要:
A track width regulating section having a track width, which is smaller than the resolution obtained by the wavelength of the light used for exposure and development of a resist, is formed between a lower core layer and an upper core layer. Since the width of the upper core layer is larger than the track width, magnetic saturation can be effectively reduced. Inclined faces are formed on the upper surface of the lower core layer so as to be inclined in directions away from the track width regulating section, thereby adequately preventing write fringing.

A thin film magnetic head includes an upper core layer and a lower core layer which are made of an Fe—M—O alloy, an Fe—M—T—O alloy or an NI—Fe—X alloy so that the upper core layer has a high saturation magnetic flux density, low coercive force and high resistivity, and the lower core layer has a lower saturation magnetic flux density than the upper core layer, low coercive force, high resistivity, and a low magnetostriction constant. Also the lower core layer is formed so that the thickness gradually decreases toward both side ends, and a gap layer can be formed on the lower core layer to have a uniform thickness. Since the lower core layer is formed by sputtering, a material having excellent soft magnetic material can be used, thereby enabling recording at high frequency.

A process for preparing a continuous optical compensatory sheet has the continuous steps of: coating a liquid of a resin for forming an orientation layer in a solvent on a surface of a moving continuous transparent film; drying the coated layer to form a transparent resin layer; subjecting the transparent resin layer to rubbing treatment to give an orientation layer; coating a coating liquid of a discotic compound in a solvent on the orientation layer to form a coated layer; drying the coated layer; heating the coated layer to form a discotic nematic phase, whereby a layer of discotic compound is formed; and winding up the transparent film.
