Title: Floppy disk device
Inventor: IIJIMA YUKIO
IPC: G11B20/14
Filed: 1994-07-25
Abstract: PURPOSE:To reduce read errors by deciding whether phase deviation is of a single-shot or consecutive while performing phase comparisons with intervals of plural data read at one time and allowing a window to be changed according to the decision. CONSTITUTION:A shifter 8 generates three-step arrangement data of outputs shifted from readout data by quantities of respective cycles of 0, 1, 2 to input respectively them to PLLs 9, 10, 11 and then three kinds of synchronizing signals are obtained by performing a phase synchronization to respective data arrangements. Then, they are compared in a comparator 12 and whether the phase deviation is caused by peak-shifts or by the rotational fluctuation of a drive is decided by whether the deviation is of the single-shot or consecutive and the phase of a data window is changed according to the decision. Thus, read errors are reduced by correcting quickly the phase deviation due to the rotational fluctuation and also by without following up to the peak-shifts.

Title: A/d converter
Inventor: YAMANE SATOSHI
IPC: H03M1/56
Filed: 1979-12-28
Abstract: PURPOSE:To simplify the constitution of an A/D converter, by using the voltage of the charge storage element which is charged and discharged by the up-pulse and the down-pulse of an up-down counter respectively for the comparison voltage. CONSTITUTION:When the charging voltage B of the charge storage element 7 is lower than the voltage level of the analog input A at the time point t1, the output C of the comparator becomes a high level with the gate 8 turned on. Then the output of the pulse generator 10 is applied to the up-terminal of the up-down counter 13 as well as sent to the charging circuit 11 to charge the element 7. When the voltage B becomes equal to the input voltage at the time point t2, the output of the comparator 5 turns to a low level to discontinue the charging. With reduction of the input A, the output of the comparator 6 becomes a high level. Thus the output of the generator 10 is applied to the down-terminal of the counter 13 as well as to the discharging circuit 12. Thus the element 7 is discharged. The digital value corresponding to the input A is obtained from the output of the counter 13.

Filed: 1992-06-04
Abstract: PURPOSE:To obtain a large drive torque by generating a phase difference be tween a rotating magnetic field generated around one rotor core and a rotating magnetic field generated around the other rotor core. CONSTITUTION:A phase shift apparatus 15 is operated so that voltages induced on the rotor windings 8, 9 of two rotating cores due to the rotating magnetic field of the main windings 3, 4 respectively provided to a couple of rotor cores at the time of driving are in the same phase, that is, a current is not flown to the diodes D3, D4 provided in parallel at the connecting points of the rotor windings 8, 9 due to the current circulating through the rotor windings 8, 9, in order to drive a synchronous motor as an ordinary induction motor. In this case, a switch S1 of the excitation windings 6, 7 is opened and the rotating magnetic field of stator induces voltages E1, E1<epsilonjtheta> on the excitation windings 6, 7. Since these voltages E1, E1<epsilonjtheta> are reversed with each other, the diodes D3, D4 are not conductive and a current does not flow into the excitation windings 6, 7. Thereby, a drive torque can be increased to realize self-driving.
