摘要： A magnetic head core and a method of fabricating same, wherein a magnetic circuit is constituted by a pair of magnetic films having a V-shaped cross section which face each other at each protrudent section through the gap material. The cross-sectional portion of the V-shaped film is exposed to the surface facing the magnetic recording medium. The protrusions of the magnetic film pair have tip planes parallel to each other and substantially perpendicular to the moving direction of the magnetic recording medium. The tip plane has a width defined by the line of intersection between the plane and the surface facing the magnetic recording medium in correspondence to the recording track width. At least one of the magnetic films has a window for winding an excitation coil. The magnetic film is formed on the non-magnetic protection member having a V-shaped protrusion. The magnetic head has superior recording and reproducing characteristics in a wide frequency band with less rubbing noise, high wear-resistivity and high productivity, and operates without the pseudo gap effect. The magnetic head core is fabricated through the steps of forming a coil winding groove in the gap forming plane of a non-magnetic core block, forming a number of parallel grooves perpendicularly to the winding groove so that a number of V-shaped protrusions are produced, forming a magnetic film on the surface of the protrusions, forming a gap plane after the magnetic film has been coated with non-magnetic material, and splitting the block and then combining the two core blocks to complete a magnetic head core.

摘要： A displacement - electricity transducer contains a movable magnetic core and a fixed magnetic core oppositely arranged so as to have predetermined gaps or clearances in at least two places. Two substantially closed magnetic circuits, each including one of the gaps, are formed by both magnetic cores, so that when the movable magnetic core is displaced relative to the fixed magnetic core while maintaining a predetermined spacing therefrom, the substantially opposite area of the gap portion in one of the magnetic circuits increases, while the substantially opposite area of the gap portion in the other magnetic circuit decreases. A first coil is wound around a part common to the two magnetic circuits, while a second coil is wound around a part not common thereto. By applying an alternating current to the first coil, an output responsive to the displacement of the movable magnetic core is derived from the second coil.

摘要： A pair of serial data signals having reciprocal signal levels are detected when a voltage of one of the serial data signals becomes larger than a voltage of the other serial data signal that is provided with an offset by a differential amplification circuit included in a signal detection circuit unit. A differential amplification circuit unit provides an offset for one of different predetermined constant voltages supplied thereto, and outputs signals by performing a differential amplification to the different constant voltages. An offset control circuit unit controls the offset provided by the differential amplification circuit unit so that voltages of the signals output by the differential amplification circuit unit coincide, and correspondingly controls the offset provided by the differential amplification circuit included in the signal detection circuit unit.

摘要： A test controller 4 has a test plan generating unit 11 for generating a test plan of a data path 2 which is formed to have a fixed control testability in which a test plan constituted by three phases, that is, the propagation of a test vector to a data input, the execution of a test and the propagation of an output response is present for each test object module. Thus, an integrated circuit is capable of supplying a test plan as a time series of a control signal to a control input of a data path, shortening a test execution time and generating the test plan at the normal operation speed of the circuit, thereby carrying out a test at an actual operation speed and an integrated circuit designing method.
