Under such conditions, the positions of a valve and a wind are set at a position 5 and this position 5 is controlled toward the value 3. In such a case, the leading control is once carried out as sown by a locus 6 to lead a level higher than the limit level 4b of the sector 4. Then the trailing control is carried out and the trailing output is stopped by the level 4b of the sector 4. Thus the valve and the wing arrive at a position 7 by undershoot. Then these valve and wing set at the position 7, i.e., the final arriving point to the value 3 are controlled toward the sector 4. In this case, the level is led up higher than the limit level 2b of the sector 2 and then trailed as shown by a locus 8. The trailing output is stopped at the level 2b of the sector 2. Thus, the valve and the wing are moved to a position 9, i.e., a final arriving point 9 against the value 1 by undershoot.

Filed: 1985-04-12
Abstract: PURPOSE:To make a voice output level constant by making the voice output level variable by a request operation from a receiving side for receiving a service of a voice response. CONSTITUTION:When a voice level which has been stored by a voice storage part 2 is low, or the level of a voice which has been reproduced by a telephone set is low due to a transmission loss in a telephone line, and it is difficult for a receiving side to listen to it, the receiving side inputs an input code prescribed in advance, in order to make the voice level variable, after an output of the voice has been ended.

Abstract: PURPOSE:To improve the signal response speed by outputting the output of 1st and 2nd circuits selectively at the output of the signal when the 1st circuit is driven by the rise of an input signal, and the 2nd circuit is driven by the fall of an input signal at high speed respectively. CONSTITUTION:An output signal S2 of the 1st circuit I responding at a high speed to the rise of an input signal S1 and an output signal S3 of the 2nd circuit II responding at a high speed to the trailing of an input signal S1 are selected by a selection control circuit III. That is, when both the output signals S2, S3 of the 1st and 2nd circuits I, II are logical 1, transistors (TRs) T13, T14 are both turned on by a reset signal S4 and the output signal S2 of the 1st circuit I is selected. On the other hand, when both the signals S2, S3 are zero, N-channel TRs T15, T16 are turned on by a set signal S4, and the output signal S3 of the 2nd circuit II is selected. Thus, the output signal S5 is formed and outputted by a signal having the fast response speed at all times to evade the delay in the output signal with respect to the input signal thereby attaining the high speed response.

IPC: G11B5/09
Filed: 1983-04-30
Abstract: PURPOSE:To erase efficiently the previous recording to record data with high reliability by subjecting a recording track area to saturated magnetization plural times to invert the direction of magnetization alternately. CONSTITUTION:An erasing head where one coil 12 is wound around an E-shaped core 11 is provided in the flow-in end of a floating head.
