IPC: G06F12/08
Filed: 1986-06-11
Abstract: PURPOSE:To improve a cache hit factor together with the increase of executing speed and to decrease the number of component parts of a cache memory, by securing such constitution where two port RAMs contain comparison parts independently of each other and two processors share a single memory. CONSTITUTION:1st and 2nd memory parts 13 and 16 are referred to via the index of a 1st processor 11 while this processor is kept under a read mode. When the results of comparison are coincident with each other at a 1st comparison part 14, a request is given to a memory part 16 for output of data. The processor 11 obtains data from the 1st port of the part 16. While the output of data is stopped via the part 16 if no coincidence is obtained from said results of comparison. Then the processor 11 obtains data from a main memory 17. Both parts 13 and 16 refer to the index of 2nd processor 12 despite the read mode of the processor 12. When coincidence is obtained from the results of comparison at a comparison part 15, a request is given to the part 16 for output of data. Then the processor 12 obtains data from the 2nd port of the part 16. While the output of data is stopped via the part 16 if dissidence is obtained from said results of comparison. then the processor 12 obtains data from the memory 17.

Title: Control method of magnetic powder concentration in wet type magnetic powder flaw detection test
Inventor: ICHIKAWA MASAAKI
IPC: G01N27/72
Filed: 1980-10-01
Abstract: PURPOSE:To perform the magnetic powder flaw detection with the proper defect detecting sensitivity at all times, by detecting the concentration of magnetic powder in the form of the intensity of light sent from a pattern of magnetic powder formed at the standard defect and then carrying out the control of concentration. CONSTITUTION:An object to be inspected receives the spray of the fluorescent photomagnetic powder liquid M from a spraying device 1 while it is shifted to be collected into a tank 2 and is then sent back to the device 1 from a pump 3 via a T- shaped tube 4. A standard test piece 11 contains an electromagnet 13 in a cylinder 12 made of synthetic resin, and a low carbon steel bar 14 having a standard defect 15 is fixed between the magnetic electrodes. The piece 11 receives the spray of a material similar to the liquid M of the device 1 from a spraying device 5, and accordingly a magnetic powder pattern 16 is formed to the defect 15. The pattern 16 emits light by the irradiation of a light 21, and this light intensity is detected by a detector 23. The pattern 16 is then sent to a control circuit 24. Then a valve 6 is actuated when the concentration becomes less than the set value. As a result, the magnetic powder liquid of high concentration is supplied into a tank 2 from a tank 7 via a tube 8. Thus the concentration is controlled.
