摘要:
A ferromagnetic material is composed of an iron alloy which contains 2 to 12% by weight of silicon and 5 to 25% by weight of at least one element selected from the group consisting of ruthenium, rhodium, palladium, iridium, platinum, gold and silver. This ferromagnetic material exhibits a high saturation flux density and good corrosion resistance. Excellent magnetic characteristics are obtained by a multilayered film which is obtained by alternatingly laminating the above ferromagnetic material and a spacer layer composed of other material. Further, a markedly increased recording density is exhibited by a magnetic head for perpendicular magnetic recording, when the end of the main pole is composed of the ferromagnetic material.

An array of thin film transistors is fabricated by forming a plurality of spaced closely adjacent metallic source and drain electrodes on an array area of a transparent substrate, forming semiconductor layers on the substrate between each adjacent pair of source and drain electrodes in overlapping relation to the edges of each such pair, covering the semiconductor layers with a gate insulation film that extends over substantially all of said array area, forming a transparent gate electrode layer over the gate insulation film, covering the transparent gate electrode layer with a photosensitive resin layer which is then exposed to light through the transparent substrate and transparent gate electrode layer with the metallic source and drain electrodes acting as masks, developing the photosensitive resin layer to remove portions thereof other than the exposed portions, and etching the transparent gate electrode with the remaining portions of the resin layer serving as masks thereby to form the gate electrodes of the thin film transistors in the array.

摘要:
A model and a workpiece are rotated synchronously, and a stylus is disposed for relative movement toward or away from the model in a direction perpendicular to the axis of rotation thereof for contact therewith. The amount of displacement of the stylus from its neutral point which occurs while it contacts the model is detected by a tracer head and is divided into a pair of components lying in a plane perpendicular to the axis of rotation of the model which are along the direction of said relative movement and along a direction orthogonal thereto. The distance between the center of rotation of the model and the center of the stylus is also detected, and is utilized together with the two orthogonal components of the displacement, the radius of the stylus, a reference displacement of the stylus as well as an established speed therefor in order to control the speed of rotation of the model and the speed of said relative movement between the stylus and the model so that the speed with which the point of contact between the stylus and the model moves along the contour of the model becomes equal to a preselected value. A workpiece and a tool therefor are disposed in a similar relationship as the relationship between the model and the stylus, and are driven in synchronism with the model and the stylus for profiling the workpiece. Where the tool contacts the workpiece over a certain width as with an abrasive belt, the contact segment of the stylus is angularly moved so as to follow the curved surface of the model, thereby detecting an angle of skew of the curved surface so that the angle of skew of the tool coincides with the detected angle.
摘要:
A liquid-crystal cell is formed with first and second transparent substrates opposing each other and a liquid crystal sealed therebetween. A plurality of display electrodes are formed in a matrix arrangement with rows and columns on the inner surface of said first transparent substrate. Gate bus lines are formed on the first transparent substrate along the respective rows of display electrodes. Source bus lines are formed on the first transparent substrate along the respective columns of display electrodes. Thin-film transistors are formed on the first transparent substrate at the intersections of a gate and source bus lines. The thin-film transistors each have a gate electrode connected to the associated gate bus line, a source electrode connected to the associated source bus line and the drain electrode connected to the corresponding display electrode. A common electrode is formed on the second transparent substrate such that it faces the display electrodes. The opposed sides of the source and drain electrodes of each thin-film transistor are constituted by tapered surfaces with the distance therebetween progressively decreased as they approach the first transparent substrate. Ohmic contact layers are formed on these tapered surfaces. A semiconductor of each thin-film transistor is formed over the source and drain electrodes via the ohmic contact layers.
