Title: Continuous casting method
Inventor: NITTA MASAKI
IPC: B22D11/128
Filed: 1993-03-10
Abstract: PURPOSE:To continuously cast a cast slab without center segregation, center porosity and internal crack, etc., by executing the rolling reduction in the spe cific condition of rolling reduction gradient to the thickness of the cast slab per the unit time. CONSTITUTION:The rolling reduction force is applied to the cast slab during drawing in the end stage of the drawing process of the cast slab in a continuous casting method. Then the rolling reduction is started from the time which solid- phase ratio at the center part of the cast slab is at most 0.05. Further, the rolling reduction is executed in the condition which the rolling reduction gradient to the cast slab thickness per the unit time satisfies the inequalities I, II and III. In the inequalities I, II and III, G means the interval (unit mm) between the mutually adjacent rolls for rolling reduction in the drawing line direction. Further, the rolling reduction started from the time which the solid-phase ratio at the center part of the cast slab is at most 0.05, uses the rolling reduction roll having 0.2-0.8 times of the cast slab width to the effective length and executes by acting from both sides at the upper and the lower parts or one side of either part of the cast slab. By this method, the center segregation can stably be eliminated.

Filed: 1983-03-24
Abstract: PURPOSE:To display the tape driven amount and the remaining time of the sound record starting position after the wrong recording is corrected, by storing previously the tape driven amount and the remaining time of the sound record starting time point into a memory. CONSTITUTION:Memory parts 310 and 311 of a processing part 3 work in response to a sound recording switch 5 to store the tape driven amount, the tape remaining time, etc. through counter parts 308 and 309 when the sound recording is started. Then the sound recording is carried out. If this recording is wrong, a wrong recording correction switch 6 is operated. Thus the flag given from a wrong recording correction flag circuit 315 is inverted to a high level, and the tape is rewound via a mechanism control part 7. When the coincidence is obtained between the output of the part 308 and the memory contents of the part 310 with said tape rewinding, the output of the circuit 315 is inverted to a low level with the coincident output given from a comparing part 312. At the same time, the tape drive is stopped. Then the contents of the part 310 and 311 are displayed in response to the designation of a memory part 314. Thus it is possible to display the tape driven amount and remaining time of the recording start position after the wrong recording is corrected.

Title: Magnetic recording and reproducing device
Inventor: SAITO MASAHIKO
IPC: H02P8/14
Filed: 1985-03-13
Abstract: PURPOSE:To make possible positioning with high speed and accuracy and movement of a magnetic head by so arranging that, in order to apply a brake during carriage movement, the voltage is lowered during movement to decrease the torque and, after the carriage approaches the target track, the rated voltage is again applied to assure an accurate positioning. CONSTITUTION:The voltage impressed to a stepping motor 27 is set to 12V during the first time t1ms. The stepping motor starts its rotation so that it starts to be shifted towards the target track. Movement over about one third of the track is completed after t1ms after which the voltage is dropped to a holding voltage of 5V. The driving force so far attracting is lowered, but the carriage continues to be moved to the target track under the force of inertia exerted by the carriage 22 and the head arm 23. A moderate braking action is produced by using 5V after t1ms therefore moderate operation is generated to reduce vibrations and to reduce the time of unstable area. Magnetic heads 20, 21 can be accurately positioned by re-setting the voltage to 12V after time t2ms and maintaining the voltage of 12V for t3ms. This results in reduced damping phenomena while promoting head positioning.
