  • Publication number: 20150113320
    Abstract: A processing apparatus includes a precursor detection unit that detects a precursor event indicating a precursor that a target process cannot be executed by a process unit, and a control unit that sends a preparation request to a substitution processing apparatus when the precursor detection unit detects the precursor event in which the preparation request requests the substitution processing apparatus being a ready state for starting a substitution processing. The control unit sends a termination request to the substitution processing apparatus when a predetermined condition is satisfied after the control unit sends the preparation request, in which the termination request requests the substitution processing apparatus terminating the ready state.

  • Publication number: 20140049929
    Abstract: A filter circuit 103 includes capacitor elements 121 and 122. The capacitor element 121 returns a common mode current included in a signal output from, a signal output terminal 111 of a semiconductor element 102, to a ground terminal 113 of the semiconductor element 102. The capacitor element 122 returns a common mode current included in a signal output from a signal output terminal 112 of the semiconductor element 102, to the ground terminal 113 of the Semiconductor element 102. The capacitor elements 121 and 122 are arranged such that the mutual inductance between a parasitic inductance of the capacitor element 121 and a parasitic inductance of the capacitor element 122 for the common mode currents is a negative value. Accordingly, the effective inductances of the first and second capacitor elements for the common mode currents are reduced, which suppresses radiation noise.
