摘要： 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.

摘要： 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.

摘要： 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.

摘要： A continuously variable belt drive transmission has a torque converter with a lockup clutch. The lockup clutch is engaged in accordance with driving conditions of the torque converter. Quantity of downshifting the transmission is decided in dependency on changing rate of speed of an input member of the transmission so that the speed of the input member coincides with speed of the engine. The transmission is downshifted by the downshift quantity and the lockup clutch is engaged so as to change the engine speed at a substantially constant rate.

摘要： A control system for a continuously variable transmission for a motor vehicle has a transmission ratio control valve for controlling the transmission ratio. The system has a drive pulley having a shiftable disc and a hydraulic cylinder for operating the disc, a driven pulley having a shiftable disc and a hydraulic cylinder for operating the disc, a belt engaged with both pulleys. When output torque of an automotive engine increases, the transmission ratio control valve is operated to increase pressure of oil supplied to the cylinder of the drive pulley, thereby preventing the transmission from downshifting.
