Title: Use frequency recording system of floppy disc medium
Inventor: HORI YUUTAROU
IPC: G11B33/10
Filed: 1979-02-13
Abstract: PURPOSE:To detect the use frequency of a floppy in advance to make maintenance efficient by storing the number of rotations in the case, where the head is placed on tracks according to presence and absence of read/write of the floppy, into the floppy. CONSTITUTION:When the read/write command of specific track and sector is issued from a CPU, rotation number write circuit 3 searches the rotation number memory area for every track unit on the floppy disc on a basis of contents of register 5 storing the track address, where the head is brought into contact, and adds the value of resister 7, which counts the number of rotations for head contact on the track, to the value of the memory area above. After that, data is transferred between a prescribed sector and the CPU by floppy disc access circuit 8. Next, the number of rotations for no read/write is accumulated in register 7. As the result, the use frequency for every track is recorded in the area of the floppy disc.

IPC: H02P3/12
Filed: 1989-01-23
Abstract: PURPOSE:To enable highly accurate follow by providing a speed feedback circuit, turning the switching elements in an arm OFF simultaneously, while subjecting the OFF time to pulse width modulation, simultaneously turning the switching elements in the other arm ON and thereby short-circuiting the motor winding. CONSTITUTION:Voltage level of a speed command 26 is lowered under a state where a signal K is brought to a level H and the gate is opened. A position detector outputs a speed signal which is then converted into a pulse signal. A level H interval of the pulse signal is determined so that an upper arm transistor and a lower arm transistor are selected. On the other hand, an F/V converter 21 converts the signal into a DC voltage. An operational amplifier 23 operates the difference between the motor speed and a speed command 26 to produce a differential signal for forming a pulse width modulation signal. When the pulse width modulation signal goes to level H, a capacitor 43 is charged and it is discharged when the pulse width modulation signal goes to a level L. In similar manner, a capacitor 47 is charged/discharged.

Then the assignment information to a memory circuit 120 is outputted and the information representing whether or not the signal of each channel is multiplexed at present via a signal line 132 is outputted. In each channel unit or module or the like, based on the said information, and in case of a data line, for example, a synchronizing flag bit is sent to a receiver side terminal equipment in case of no multiplex and in case of a voice line, the operation of a decoder is stopped synchronously with a coder at the sender side. Thus, the internal state of transmission/reception is kept the same and the control not causing deterioration of quality is applied at re-multiplexing state.

Abstract: PURPOSE:To grasp exactly the position of the initial ends of the second and subsequent originals, by reading out a stored value to a counting device, and starting to count the next original based on said value, when a terminal of the previous original reaches a read position and counting by a counting device has been completed. CONSTITUTION:When a terminal of the previous original has reached a read position, namely, when a count value of a counting circuit 11 has reached a distance portion M of an original detecting B detector 3 and a read position by an original reader 6, a control signal of a counting end is outputted to a driving controlling circuit 10 from the circuit 11, and the counting operation is ended. This circuit 10 converts a driving signal corresponding to a read speed to a driving signal of a prescribed speed and outputs it, to a driving motor 8. In this case, the circuit 11 starts to count from a count value corresponding to a distance in which the initial end of the next original has moved beyond the detector 3, and when its count value has reached M, it is decided that the initial end of the next original has come exactly to the read position. By repeating this operation, the transmission can be executed continuously.
