IPC: G06F13/00
Filed: 1989-10-26
Abstract: PURPOSE:To prevent an input/output device from being cleared by providing a control means which inputs information on the state of the input/output bus of the input/output device when receiving a forcible end instruction from a central processor and restarts processing at a processing stage indicated by the input/output bus state. CONSTITUTION:When the input/output device 4 performs input/output processing while sending and receiving information to and from an input/output controller 1, a control means 3 reads the state of the input/output bus 5 in response to a clear instruction sent out of the central processor 6. Then the state of the input/output bus 5 indicates which stage of the processing the input/output device 4 carries out, so the input/output controller 1 performs control so as to restart the processing not in the initial state, but at the processing stage judged from the state of the input/output bus 5. Namely, even when the clear instruction is sent out of the central processor 6 while the input/output device 4 is in input/output processing, the input/output device 4 does not return to the initial state and restarts the processing at the processing stage in the state of the input/output bus 5 at the point of time. Consequently, information which is being processed is never lost.

Filed: 1988-11-07
Abstract: PURPOSE:To measure the current flowing through an object to be measured without receiving other effect by allowing linear polarized beam having a plane of polarization in a predetermined direction to be incident on a Faraday element and aligning the beam path thereof with the straight line connecting arbitrary two conductors. CONSTITUTION:Linear polarized beam having a plane of polarization in a predetermined direction obtained by passing the beam from the input fiber 13 of a plane-of-polarization preserving optical fiber through a polarizer 14 is allowed to be incident on a Faraday element 10. Subsequently, the position of the element 10 is adjusted so as to align the beam path P of the element 10 with the straight line L connecting conductors A, B in the shortest distance. At this time, the magnetic field having intensity of HA+HB in the direction crossing the beam path P at a right angle and the magnetic field having intensity of Hc in the direction forming an angle theta with respect to the beam path P act on the element 10 from conductors A, B, C to prevent the rotation of the plane of polarization of the linear polarized beam propagating through the element 10. Therefore, the intensity of the beam emitted from the detector arranged to the end part of a beam emitting fiber 16 to obtain output and, on the basis of the this output, the angle theta of rotation of the plane of polarization is calculated and, further, the value of the current flowing through the conductor C is calculated.
