And when implementing this discharging operation, can also be superimposed with the enforcement soup at basic action sequence on the time and clean the needed elemental motion sequential time.Here, implement soup and clean the needed elemental motion sequential time, refer in and make valve V7 in opened condition the schedule time before being accumulated in the water enforcement discharging operation within the stopple coupon 7, cleaning fluid is injected within the stopple coupon 7, thereby can utilize the water that is injected with cleaning fluid when implementing drain operation, the medial surface of detecting unit 3 be implemented to clean the action sequence time of usefulness.
And when implementing this discharging operation, valve V4 and valve V5 are alternately opened, thereby can be by the to-and-fro movement of cleaning shoe 8, form eddy current at transparent panel 2a, 2b and 8 of cleaning shoes, thus to implementing to peel off removal, thereby implement cleaning operation more completely attached to everywhere dirt.
This enforcement soup cleans the needed elemental motion sequential time, also can constitute by cleaning the special-purpose action sequence time.The action sequence time of cleaning special use refers to opens valve V6, import the water of scheduled volume to stopple coupon 7, after valve-off V6, open valve V7 and inject cleaning fluid, open valve V3 and implement drain operation, alternately open valve V4 and valve V5 simultaneously, enforcement within the detecting unit 3 is cleaned the action sequence time of usefulness by the to-and-fro movement of cleaning shoe 8.
Aforesaid is the elemental motion sequential time, can back and forth carry out the operation that videotapes of image in this manner.
In this form of implementation, in order under the state that keeps block deposit seed shape, it to be directed into detecting unit 3, be valve V6 to be implemented open and close controlling, yet also can adopt other open and close controlling method according to the mode of valve being implemented open and close controlling by the unit interval flow of flow detector 5.If for instance, can also adopt the method for using the meter enforcement open and close controlling.In other words be exactly, can be under the state that keeps block deposit seed shape, its " block deposit seed importing optimum velocity " that is directed into detecting unit 3 being implemented instrumentation in advance, import the decompression amount that optimum velocity converses pressure loading valve 31,32 by this bulk deposit seed, and in view of the above the decompression time of pressure loading valve 31,32 is implemented control.When reality is used, can also be with should decompression amount related coefficientization, and be combined in action sequence and implement control corresponding in the time.
Schematic procedure chart below with reference to image processing procedure is as shown in Figure 5 used describes concrete image processing procedure.
At first in program step S10, videotape commencing signal to 11 outputs of electric charge coupled mode (CCD) gamma camera, the block deposit seed shape that remains static is implemented to videotape by action sequence time controller 40.The pictorial data that videotapes a frame frame of acquisition is kept in the visual reservoir of visual analytical type special purpose computer (PC) 50.
