Patent JP-H07240698-A (JP)
Title: Data communication system
Inventor: NAKAYA YOSHIYUKI
IPC: H04B1/59
Filed: 1994-02-28
Abstract: PURPOSE:To supply power at all times to a receiving equipment that receives data transmission and power supply by means of signals sent from a sending equipment. CONSTITUTION:A control circuit 11 always applies a drive signal S1 to an oscillation circuit 12 and selects a level of a switching signal S2 fed to a frequency variable circuit 13 to a high level or a low level depending on the content of transmission data RD1. The oscillation circuit 12 outputs a reference signal to the frequency variable circuit 13 while the control circuit 11 sends a drive signal S1. The variable frequency circuit 13 frequency-divides the reference signal into a frequency f1 when the switching signal S2 is at a high level and into a frequency f2 when the switching signal S2 is at a low level, and then the frequency-divided signal is fed to a transmission circuit 14. A transmission coil L1 of the transmission circuit 14 sends an intermittent wave signal whose frequency is f1 and a complementary signal whose frequency is f2 complementing the whole range of the intermittent part of the intermittent wave signal.

Title: Resistance fluctuation compensation circuit for mr head
Inventor: ASAI KATSUTOSHI
IPC: G11B5/39
Filed: 1993-02-19
Abstract: PURPOSE:To always send a read signal from a disk medium in normal condition even when an MR head is heated by obtaining a diffrential signal using two MR heads. CONSTITUTION:Bases are respectively fixed on zero potentials and collectors are connected to the power of positive polarity via resistors 1 and 2 connected with them. Two transistors 4 and 5 are provided to make a current flow to the power of negative polarity via magnetic resistance effect elements 6 and 9 connected with them and a constant current source 8. Then, signals read from a magnetic recording medium based on resistance values changed corresponding to the changes of the magnetic fields are generated between the collectors of the transistors 4 and 5 by the elements 6 and 9 and thus, the elements 6 and 9 are connected so that the directions of the currents of the same value flowing to the elements 6 and 9 having current polarities in the increase/decrease of the resistance values are made mutually opposite against the current polarity. Thus, by obtaining the differential signal using two elements 6 and 9, the reading signal from the disk medium is always sent in the normal condition.

Title: Driving method and circuit for self-arc-extinguishing element, and power converter using that driving circuit
Inventor: TOKUNAGA KIICHI
IPC: H02M7/537
Filed: 1992-02-17
Abstract: PURPOSE:To enable such proper protective operation as to cut off a faulty element from a main circuit quickly, etc., by distinguishing between the temporary overcurrent due to noise, etc., and the overcurrent due to arm short, etc. CONSTITUTION:In case of temporary overcurrent due to noise, etc., normal operation is enabled immediately after suppressing of the current, while in case of a short-circuit current protective fuse of a main circuit is blown out by the suppressed current and disconnected from the circuit, by lowering the on-gate voltage of a self-arc-extinguishing element with a fixed time constant to a value higher by a certain voltage than the threshold voltage of the self-arc- extinguishing element (10) during an interval when the main circuit current of the electrostatic self-arc-extinguishing element IGBT exceeds the set current (9). Moreover, it is desirable to cut off the short accident further quickly by raising it to the specified on-gate voltage after drop of the on-gate voltage. Hereby, the spread of accident to other sound element or power converting circuit can be prevented, and the drop of output voltage is suppressed by suppressing the circulation current between other power converters, thus the reliability can be improved.
