An immersion nozzle for continuous casting of steel supplies molten steel into a mold. At least a part of the immersion nozzle is formed of a refractory having a desulfurizing ability. A method for continuous casting of steel employs the immersion nozzle to supply molten steel into a mold using the immersion nozzle for continuous casting.

A molding attaching structure includes a sash provided on an automobile door, an outer sash mounted to the sash, and a molding mounted to the outer sash. When a door glass of the door is fully closed, the molding has its one side end laid over an edge of the door glass. The molding has its outer surface substantially flush with an outer surface of an automobile body. The outer sash includes a molding attachment part projecting outwardly therefrom. The molding attachment part includes an extension part and an edge part. The edge part includes a first portion extending from the extension part away from the door glass and having a distal end bent back, and a second portion extending from the distal end across the extension part towards the door glass.

In a flat surface illumination device or a liquid crystal display panel, with an aperture disposed in a frame or a case, comprising a circumferential section in which a central section receiving and supporting the light guide and the like is removed, a warp preventing means is formed in such a manner to cross the aperture. The warp preventing means comprises a long and narrow zonal thin plate in which two or more beading processes are performed.

The proposed magnetic storage apparatus has the following features. The frequency at which data is recorded is selected to be 45 MHz. The thickness, resistivity and relative permeability of the magnetic film of which the magnetic poles of the magnetic head used in the apparatus are made are designed considering the eddy current loss. Also, the relation of &mgr;d2/&rgr;≦500 is satisfied where d (&mgr;m) is the thickness of the magnetic film of which the magnetic poles of the magnetic head are made, &rgr;(&mgr;&OHgr;-cm) is the resistivity, and &mgr;is the relative permeability in a low-frequency range. Under these conditions, the amount of attenuation of recording magnetic field is reduced to 10% or below, and problems of writing blur and overwrite value variation which occur as the recording frequency changes can be solved. Moreover, the media data rate is 15 megabytes per sec., and the areal data-recording density is 500 megabits per square inch or more.
摘要:
The magnetoresistance effect element is of a multilayered structure having at least magnetic layers and an intermediate layer of an insulating material, a semicondutor or an antiferromagnetic material against the magnetic layers, and the magneto-resistance effect element has terminals formed at least on the opposite magnetic layers, respectively, so that a current flows in the intermediate layer. The film surfaces of all the magnetic layers constituting the magnetoresistance effect element are opposed substantially at right angles to the recording surface of a magnetic recording medium. Therefore, the area of the magnetic layers facing the recording surface of the magnetic recording medium can be extremely reduced, and thus the magnetic field from a very narrow region of the high-density recorded magnetic recording medium can be detected by the current which has a tunneling characteristic and passes through the intermediate layer.

An electrical base 32 having a stationary detection element 31 is fixed to a body case 11 movably supporting a spindle 13, and a synthetic resin made scale holder 34 is provided to synchronize with the spindle 13 and move through a guide 33. In addition, a scale 36 having a movable detection element 35 is adherently fixed to the scale holder 34 at a plurality of points. More specifically, a projection 51 is fixed through an adhesive layer 52 to the back face of the scale 36, and held in a accommodating hole 46 formed in the scale holder 34, and then adhered through an adhesive layer 53 in the circumferential direction. As a result, the reduction in weight can be achieved and a disadvantage with the reduction in weight (which is that a gap between a stationary detection element and a movable detection element is changed) can be resolved.
摘要:
A magnetic storage apparatus exploits the inherent characteristics of a magnetoresistive element to improve the performance of a magnetic head employing the element. Variations in element height or element thickness of the magnetoresistive element are considered in the selection of a sense current appropriate to the element size, by measuring the voltage between the terminals of the magnetoresistive head and controlling the sense current so that the output reference voltage approaches a predetermined value. In another embodiment, the sense current is controlled so that the voltage amplitude or a reference amplitude are set to a predetermined value. In both embodiments, a conversion table is preferably used to relate voltage amplitudes with sense currents, whereby an appropriate sense current is selected based upon the voltage amplitude.

The proposed magnetic storage apparatus has the following features. The frequency at which data is recorded is selected to be 45 MHz. The thickness, resistivity and relative permeability of the magnetic film of which the magnetic poles of the magnetic head used in the apparatus are made are designed considering the eddy current loss. Also, the relation of .mu.d.sup.2 /.rho..ltoreq.500 is satisfied where d (.mu.m) is the thickness of the magnetic film of which the magnetic poles of the magnetic head are made, .rho. (.mu..OMEGA.-cm) is the resistivity, and .mu. is the relative permeability in a low-frequency range. Under these conditions, the amount of attenuation of recording magnetic field is reduced to 10% or below, and problems of writing blur and overwrite value variation which occur as the recording frequency changes can be solved. Moreover, the media data rate is 15 megabytes per sec., and the areal data-recording density is 500 megabits per square inch or more.
