摘要： A semiconductor device such as a Schottky-barrier rectifier diode is disclosed which has a barrier electrode formed on a semiconductor substrate of gallium arsenide or the like. Formed around the barrier electrode is an annular resistive layer, typically of titanium oxide, creating a Schottky barrier at its interface with the semiconductor substrate. The resistive layer has a sheet resistance of more than 10 kilohms per square. In order to prevent preliminary breakdowns from taking place at the peripheral part of the resistive layer before final breakdown of the device, the sheet resistance of the resistive layer is made higher as it extends away from the barrier electrode. For the ease of manufacture, the resistive layer can be divided into two or more annular regions of distinctly different sheet resistances.

摘要： A Hall-effect semiconductor device is formed on a metal-made baseplate, as of nickel-plated copper, via a magnetic layer of Permalloy or the like. Higher in magnetic permeability than the baseplate, the magnetic layer is designed to reduce the magnetic resistance of the flux path. A plastic encapsulation thoroughly encloses the semiconductor device, magnetic layer, and baseplate.

摘要： A magnetic head for perpendicularly magnetizing a magnetic recording medium having a first magnetic pole to reverse the magnetization in the magnetic recording medium which has been magnetized beforehand in a certain direction, and a second magnetic pole to control reversal of the magnetization in the recording medium effected by the first pole. This construction (1) provides a high density multi-track structure in the head; (2) increases reproduction output, while lessening influence thereon due to a spacing loss by use of a magnetic material and a magneto-resistive element for the respective magnetic poles; (3) provides lower power consumption and fringe effect noise, and smooth running of the recording medium by constructing the first magnetic pole with a permanent magnet, particularly, in cylindrical form; (4) miniaturizes the magnetic head by reducing the number of the parts, by making one of the magnetic poles the first and second auxiliary magnetic poles, and forming an erasing magnetic pole with the first auxiliary magnetic pole, to improve the writing efficiency; (5) simplifies manufacturing, improves wear-resistance of the poles, and provides high density recording by forming the permanent magnet in a thin film on the recording medium sliding surface of the first magnetic pole by thin film deposition; and (6) prevents cross-talk by providing a load-sharing type winding on one of the poles to reduce the number of windings, and by giving an azimuth angle to the magnetic pole, and improves recording efficiency by connecting both poles.
