Abstract: PURPOSE:To perform a monitor of soundness of a structure with an improved S/N, by setting a level discriminating threshold based on a peak value of outputs, added a plural number of times, from a plural number of elastic wave detecting sensors. CONSTITUTION:The elastic waves from a mimic elastic wave producing source 3 are detected by sensors 2a-2d at a plural number of spots of a structure 1 such as the pressure container of a reactor plant, and is added N times by means of adders 6a-6d to reduce a noise to N1/2. A ratio of a peak value of the addition outputs to a reference peak value is decided by peak detetors 10a-10d and comparators 11a-11d, and the number of addition times at each of the adders 6a-6d is controlled in inverse proportion to the addition output to make a peak value uniform. Based on the peak value, thresholds level discriminators 9a-9d are set by threshold setters 12a-12d and a position of a signal source 3 is decided with an improved S/N by a time lag between signals through the discriminators 9a-9d to perform a correction. A structure is monitored in a similar manner with a better S/N corresponding to elastic waves from a destruction spot in the structure.

Abstract: PURPOSE:To reduce the load on an operator and to prevent an error to establish the type of magnetic disk device or to prevent forgetting to establish the type of the disk device, by discriminating and recognizing automatically the type of the disk device that is connected to a magnetic disk controller. CONSTITUTION:A magnetic disk device 2 performs a seek operation, i.e., the positioning of a magnetic head to a prescribed cylinder or performs a rezero seek operation, i.e., resetting the magnetic head to a cylinder zero state in response to a device type discriminating signal (b). Then the device 2 transmits a seek end signal (c) when either one of said operations is through. While a track zero signal (d) is transmitted prior to the signal (c) when the device 2 performs the rezero seek operation. Then no track zero signal (d) is transmitted as shown by a dotted line if the device 2 performs the seek operation. Therefore, the signal (d) is discriminated by a JK flip-flop 1-7 at the rise of the signal (c). Thus the type of the device 2 can be discriminated.
