摘要： A method for continuous rolling includes flash-butt welding to form a continuous billet by joining a rear end of a preceding billet with a front end of a succeeding billet, removing burrs from a welded portion of the joined part, and continuously rolling the joined continuous billet in a rolling mill group. The flash-butt welding step includes the use of two travelling welders arranged in series and spaced at a distance along the direction of movement of the continuous billet corresponding to the length of the billet being welded. The travelling welders synchronously move with the continuous billet, and separately and simultaneously weld the continuous billet to another billet by flash-butt welding so as to extend the length of the continuous billet.

摘要： An oil concentration meter includes a sample cell for receiving an oil sample that can be irradiated with infrared rays from a light source. A first interference filter having a design wavelength of 3.4 .mu.m is positioned before a measuring detector, while a second interference filter transmitting a band range between 1 .mu.m and 5 .mu.m is positioned in front of a reference detector. A logarithm of the ratio of the reference detector output to the measuring detector output is used for determining the oil concentration in a sample.

摘要： A tape cassette including a rib projecting upwardly from a bottom wall of a cassette case at a position between the center and one side of a tape drawing recess formed at the front of the cassette case, the rib being disposed close to the back surface of the tape, and a projection that projects from a back lid which, in a closed position, protects the back surface of the tape. When the back lid is rotated to reach an open position, the projection is kept in contact with an upper end of the rib. Accordingly, even when a part of the tape is lifted by the back lid during a lid opening operation, the tape is prevented from entering behind the rib, thereby also preventing tape jamming and damage to the tape player.

摘要： In a motor speed controller for controlling an AC motor to be driven at a variable speed, a signal proportional to a load torque and a signal proportional to an output torque of the AC motor are found by current detecting means for detecting the primary current of the AC motor, and integrated over the speed changing period, and the integrated values are divided by the values corresponding to the amounts of speed change during the speed changing period so that the moment of inertia can be computed. In addition, there is provided means for changing the rate of output frequency change caused by the output frequency command into a value according to the calculated moment of inertia. Moreover, there is provided a circuit for detecting a sudden change of the calculated moment of inertia, so that when a sudden change occurs, an abnormality signal is generated.

摘要： In spatial vector control of a pulse width modulation (PWM) inverter adapted for variable speed drive of an induction motor, a difference vector between magnetic flux vectors occurring during adjacent sampling periods is generated by synthesizing a zero vector and voltage vectors in such a manner that a resultant voltage vector always includes as a component a minimum unit of a zero vector or a voltage vector, whereby even when the angular speed of rotation of the magnetic flux changes, the switching frequency of the PWM inverter is prevented from decreasing and the current ripple is reduced.

摘要： In driving a stepping motor which, for example, is used to effect tracking movements of a head in an electronic still camera or other magnetic disk recording and/or reproducing apparatus, and which has a rotor and a plurality of phases to which input pulses are applied in predetermined sequences for establishing excitation states by which the rotor is stepped to respective positions, the input pulses are controlled for alternating between first and second excitation states corresponding to adjacent stepped positions between which it is desired to bring the rotor to rest. Such alternation is initially effected at a relatively low frequency so that the rotor oscillates between the stepped positions corresponding to the first and second excitation states, respectively, and then the frequency of alternation between the first and second excitation states is gradually increased to a value at which the rotor no longer oscillates with such alternation and comes to rest at a position between the stepped positions. A duty ratio is selected for the first and second excitation states which inversely corresponds to the ratio of the distances from the desired position of rest of the rotor to the stepped positions of the latter corresponding to the first and second excitation states, respectively, and such duty ratio is applied to the alternation between the first and second excitation states at least during the increasing of the frequency of alternation to the value at which the rotor no longer oscillates.
