摘要： A method for manufacturing a magnetic head which includes a lower write pole having a projection, an upper write pole having a projection opposed to the projection of the lower write pole, and a magnetic gap interposed between the projection of the upper write pole and the projection of the upper write pole, comprising: a first step of making the magnetic gap on the projection of the lower write pole; a second step of making a non-magnetic material layer on the lower write pole, the non-magnetic material layer having a projection on its top surface in positional alignment with the projection of the lower write pole; a third step of making a mask layer on the non-magnetic material layer, the mask layer having an opening in which the top surface of the projection of the non-magnetic material layer is exposed; a fourth step of making a curved recess in the non-magnetic material layer by isotropically etching the non-magnetic material layer through the opening of the mask layer; a fifth step of making an approximately tapered recess down from the bottom of the curved recess by anisotropically etching the non-magnetic material layer through the opening of the mask layer; and a sixth step of making the upper write pole by burying a magnetic material in the tapered recess and the curved recess is provided.

摘要： At least one magnetic pole out of a pair of magnetic poles is provided with a T-shaped magnetic pole having a magnetic pole chip at the position contacting with a magnetic gap and an auxiliary magnetic pole which is wider than thereof. The proximity of an air bearing surface of the T-shaped magnetic pole is composed of a laminated film containing a magnetic material layer with a high saturated magnetic flux density which composes the magnetic pole chip and a portion of the auxiliary magnetic pole and a magnetic material layer with a low saturated magnetic flux density which composes the remaining portion of the auxiliary magnetic pole. When the front portion of the magnetic pole with the track width of 1.8 &mgr;m or less is composed of a laminated film containing a magnetic material layer having a high saturated magnetic flux density and a magnetic material layer having a low saturated magnetic flux density, the thickness of the magnetic material layer having the high saturated magnetic flux density is 0.5 &mgr;m or more. According to the above described magnetic pole, the magnetic saturation near the tip portion of the magnetic pole is controlled, so that preferable magnetic field strength and magnetic field gradient can be attained when the track width is narrowed.

摘要： A photosensitive material such as film is conveyed while the widthwise edges thereof are guided by width guides. The width guides have an adjusting part such as a screw to adjust the position thereof when the width of the photosensitive material changes. The adjusting part, even when the width dimension of the sensitized material does not change, is driven at a specified interval such as every few hours to remove a precipitate such as a developer which is deposited on the adjusting part.

摘要： A biochemical analysis apparatus comprises a sample accommodating region, a refrigerator for keeping cool a long test film containing a reagent which reacts with a liquid sample to give rise to a change in optical density, and a test film conveyor for sequentially pulling out the long test film from the refrigerator. A sample applicator takes up the liquid sample from the sample accommodating region and applies it to the long test film at the position to which the long test film has been pulled out of the refrigerator. An incubator maintains the sample-applied portion of the long test film at a predetermined temperature for a predetermined time. A detector irradiates light to the sample-applied portion of the long test film, and measures the optical density given rise to by the reaction during or after the passage of the predetermined time.
