Title: Magnetic sensor for iron loss measurement of magnetic material
Inventor: NAKAMURA TADAMASA
IPC: G01R33/12
Filed: 1979-09-26
Abstract: PURPOSE: To always ensure a correct measurement of the iron loss at a correct point of measurement and with no shift caused by vibration and a fixture at the point of measurement, by avoiding the zero of the sucking force of the magnetic sensor although the instantaneous value of the exciting current may be set to zero and always securing the function of the sucking force.  
     CONSTITUTION: When the primary coil 8 is excited by the single-phase AC, the secondary short circuit current flows to the shading coils 10 and 11 by the function of a transformer caused by the AC magnetic flux in the iron core 7. This short circuit current gives a hindrance to the change of magnetic flux at the parts of the protruded pole pieces 15 and 16, and thus the magnetic flux at the part of pieces 15 and 16 each varies later than the change of magnetic flux at the part of the core 7, i.e., the pole piece 14. Accordingly, if the coil 8 is excited by the single-phase AC, a phase difference is caused between the magntic flux flowing to the magnetic material (not shown in the figure) through piece 14 and that flowing to the magnetic material through the pieces 15 and 16. Thus a phase difference is caused also for the sucking force. And the sucking force of both sides never become zero at one time although the instantaneous value becomes zero for the exciting current of the coil 8. As a result, the magnetic sensor 6 has no shift by the vibrations and is held at a point of measurement.

Filed: 1990-05-15
Abstract: PURPOSE:To stably achieve segregation improving effect under light rolling reduction by setting two or more sets of roll pairs differ in the rolling reduction times, using the total rolling reduction quantity of each set to derive the rolling reduction quantity calculating equations for each roll and controlling the limitation of roll gap and the rolling reduction force so as to make the rolling reduction quantity suitable. CONSTITUTION:The actual value K.B in plural sets of the rolls can be counted back with the equation 2 from the measured whole rolling reduction in each roll pair. The constants (a) and (m) in the equations 3, 5 are decided so that K.B calculated from the measured rolling reduction and the total of square of difference of K.B shown in the equation 4 and A in the equation 1 become the min. The rolling reduction is made to suitable, by controlling the rolling reduction force P and roll radius R with the equation 4 by using the decided (a) and (m), and in the case the rolling reduction is too much, a spacer is inserted into between bearings in the roll interval to limit the rolling reduction. By this method, the segregation improving effect under the light rolling reduction can be stably achieved.

Abstract: PROBLEM TO BE SOLVED: To peel off the resin outer layer and to enough water-tightly connect resin inner layer pipes with together through sleeve connection by providing annular projections in the longer direction at an interval on the inner peripheral face of a nipple which is passed through the resin inner layer pipe. SOLUTION: An annular resin is extruded from a mold for pipe molding of an extruder and is cooled and solidified by means of a forming tube and this outer diameter-restricted resin inner layer pipe is passed through a nipple 31 of a crosshead of an outer layer extrusion molding apparatus and a resin for an outer layer extruded between a die 32 and the nipple 31 is extruded and covered on the outer diameter- restricted resin inner layer pipe. Annular projected parts 33 are provided at two positions at an interval on the inner face of this nipple 31.  In this instance, the outer face of the resin inner layer pipe is only brought into contact with the annular projected parts on the inner peripheral face of the nipple and therefore, as it is prevented from being brought into contact with the inner peripheral face of the nipple over a wide area, softening by heating can be prevented from occurring and heat fusion between the resin inner layer pipe and the resin outer layer can be sufficiently suppressed. In addition, adhered matter on the resin outer layer can be peeled off without remaining and connection is performed with sure water-tightness.
