Abstract: The heat-treatment apparatus for steel plate has a plurality of transfer rolls for transferring steel plate in the horizontal direction and at least one induction-heating unit for heating the steel plate. The induction-heating unit is positioned between specified adjacent transfer rolls. At least an induction-heating unit located at the most upstream side among the induction-heating units is provided with at least one pressing roll at outlet thereof to press the steel plate from above. At least the pressing roll located at the most upstream side among the pressing rolls is positioned above and facing the transfer roll located at outlet of the induction-heating unit. Owing to the heat-treatment apparatus for the steel plate, desired heat treatment can be given to the steel plate even with the induction-heating unit without adversely affecting the travel of the steel plate.

Abstract: There is provided a method for restraining deformation of a nip roll, in which polygonal deformation of nip rolls that are in contact with each other is restrained, so that vibration produced by the deformation is decreased. The diameter ratio between the first and second nip rolls 1 and 2 is set at a value different from 1, by which both of the numbers of polygon sides of the rolls 1 and 2 are prevented from becoming integers or values close to integers. Thereby, polygonal deformation of nip rolls that are in contact with each other, so that vibration produced by the deformation is decreased.

Abstract: C-shaped inductors for induction heating a heated steel material that is carried via table rollers. Each C-shaped inductor includes a C-shaped iron core having a pair of legs facing each other by sandwiching a gap through which the heated steel material passes, and heating coils wound around the pair of legs of the C-shaped iron core. A ring-shaped iron core for restricting induced currents generated in the heated steel material is disposed near the C-shaped inductors, and the heated steel material passes through the gap of each C-shaped inductor.

Abstract: In order to inhibit a fired multilayer ceramic electronic component from delamination resulting from combustion of resin contained in conductive paste which is applied to internal conductors of the multilayer ceramic electronic component, the conductive paste is prepared by adding at least 1 percent by weight of terpene sulfide and/or mercaptan of R--SH in which R is a hydrocarbon radical having 8-16 carbon atoms to metal powder of Pd, Ag or Pd-Ag as an additive and kneading the same with an organic vehicle.

Abstract: A chip-type coil whose terminal electrodes are formed directly on a magnetic core and each comprise a mixture of electrically conductive material with insulating material, so that specific resistance of the terminal electrode can increase so as to reduce an eddy current flowing in the terminal electrode, thereby preventing Q-deterioration in the chip-type coil. Moreover, the chip-type coil is allowable of Q-deterioration caused by metal plating, thereby enabling the terminal electrodes to be applied with metal plating.
