A process is disclosed for the production of a non-oriented electromagnetic steel strip having its magnetic characteristics uniformly retained in the product coil. The process involves by full- or semi-processing, hot rolling a steel slab containing not more than about 0.03% by weight of C, not more than about 3% by weight of Si and not more than about 2% by weight of Al such that the equation [Si wt %]+3 [Al wt %]-6 [C wt %] is in the range of about 0 to 2; and cold rolling the hot rolled steel strip in a known manner, followed optionally by finish annealing and also optionally by skin-pass rolling. The coil is finish rolled at a peripheral roll speed between about 500 to 1,500 mpm at the final stand. The peripheral roll speed at the final finish rolling stand is also controlled within a range of no more than about 300 mpm. Hot rolling is completed at a temperature Tf (.degree. C.) in an alpha-phase temperature zone and not less than about {750+30 ([Si wt %]+3 [Al wt %]-6 [C wt %])}.

This invention is directed to a method of producing a non-oriented magnetic steel sheet involving a series of processes including performing hot rolling process on a steel slab containing no more than about 0.01 wt % C, no more than about 4.0 wt % Si, no more than about 1.5 wt % Mn, no more than about 1.5 wt % Al, no more than about 0.2 wt % P, and no more than about 0.01 wt % S, performing thereto at least one cold rolling process including an optional intermediate annealing process, and then performing a finishing annealing process. The hot rolling process further includes a step which reduces thermal irregularity formed during slab heating; this step involves maintaining a sheet bar, obtained by rough-rolling of the steel slab, at a temperature ranging from about 850.degree. to 150.degree. C. The hot rolling process also includes a step which promotes the growth of fine precipitated particles by applying strain to the sheet bar. Magnetic steel sheet thusly obtained possess uniform magnetic properties and thickness in the coil.

A low-iron loss grain oriented electromagnetic steel sheet subjected to final finishing annealing has a plurality of linear grooves formed on surface of the steel sheet in a direction across the rolling direction, so as to improve the magnetic characteristics of the steel sheet. The linear grooves have a substantially rectangular cross-sectional shape in which the angle of a groove side wall to the direction of the thickness of the sheet is about 60.degree. or less. Projections are present at a bottom portion of the groove, and the depth at the top of the projection at the groove bottom is at least about 1/2 of the maximum groove depth. The steel sheet maintains a low iron loss even after stress relief annealing. The present invention provides a method of stably producing the steel sheet.

In an apparatus for recording a video signal having interlaced fields on a recording medium sequentially using a plurality of rotating heads, a rotational phase of a rotating head relative to a vertical synchronizing signal of the video signal to be recorded is relatively switched for a period corresponding to a phase difference between a vertical synchronizing signal and a horizontal synchronizing signal of each field. It is thereby possible to obtain an excellent video signal without producing discontinuity of horizontal synchronizing signals in a reproducing operation even if a video signal of each field is recorded using any of the plurality of rotating heads having different rotational phases. At that time, objective rotational phases of a rotating cylinder provided with the plurality of rotating heads are present in the same number as the number of rotating heads. Hence, the speed of the start-up synchronizing operation is increased.

A continuously variable belt-drive transmission has a primary pulley operatively connected to an engine and a secondary pulley operatively connected to wheels of a motor vehicle, a primary cylinder and a secondary cylinder, and a hydraulic circuit having an oil pump. Primary pressure for the primary cylinder is generated by reducing secondary pressure. Steady flow rate in the primary system in a steady state is calculated, and transient flow rate in the primary system in a transient state is calculated. A primary pressure changing rate is determined to the value that the sum of secondary flow rate, the steady flow rate, and the transient flow rate becomes smaller than a discharge flow rate of the pump. In response to the primary pressure changing rate, a primary pressure control valve is operated so as to maintain balance of flow rate between the primary system and the secondary system.
