Patent JP-S61115308-A (JP)
Title: Superconducting device
Inventor: URATA MASAMI
IPC: H02H7/00
Filed: 1984-11-12
Abstract: PURPOSE:To enable the protection of constituent elements without fail even when a persistent current switch is quenched, by a construction wherein a protective semiconductor element is connected to a coil element reversely in direction to a protective element for the persistent current switch, and a current flowing through said semiconductor element is made to flow through a heater of the persistent current switch. CONSTITUTION:It is assumed that a persistent current flows through superconducting coils 1 and 2 and a persistent current switch 3. If the superconducting coil 1 is quenched under the condition, a forward voltage is applied also on a protective semiconductor element 7 and thus a current flows through this element. Since the current flows also through a heater 8 of the persistent current switch 3 on the occasion, the persistent current switch 3 is quenched as well. Therefore a voltage occurs also at both ends of the persistent current switch 3, and consequently the current flows through a protective semiconductor element 6 as well. Even if the quenching of the superconducting coil 1 is not propagated to the superconducting coil 2, the accumulated energy of the superconducting coils 1 and 2 is consumed by the protective semiconductor elements 7 and 6, and thus each component is protected without fail.

Title: Automatic loop gain control circuit
Inventor: MORISHIMA MORIHITO
IPC: G05B13/00
Filed: 1988-09-21
Abstract: PURPOSE:To automatically set the loop gain at the optimum value at all times by applying the disturbance signal having such a frequency that sets the loop gain approximately at 0dB to a servo subject, detecting the level of the feedback signal outputted from the servo subject, and controlling the loop gain so as to keep the level of the feedback signal at the fixed value set previously. CONSTITUTION:The frequency of the output signal of a disturbance generator 11 is set at the value with which the loop gain is approximately set at zero. This disturbance signal of the generator 11 is applied to a focus driver 4 via an adder 8, and an optical pickup 3 outputs an error signal having a frequency equal to that of the disturbance signal. Then the level of the error signal is detected by a measurement circuit 20 and given to a computer 7. The output of the circuit 20 is compared with a target level every time a fixed time passes, and a control signal is outputted to an amplifier 6 according to the result of the comparison. Then the output of the generator 11 is set at zero and at the same time the computer 7 is inactivated when the output of the circuit 20 is converted to the target level. Hereafter the normal servo control is performed by a focus servo controller 5.

When describing a synchronizing control of a data operation, when the start and the end of an operating procedure are brought to a transition, respectively, and a condition required for the start and the end is defined as a place, most of synchronizing controls required for a practical use can be realized. Also, when a vector expression of the Petri net is used, the operation for the synchronizing control can be executed by three vector operations of size comparison, subtraction and addition of every element of the vector. The size comparison can be replaced with a non-negative decidion of a result of subtraction.
