Title: Runaway detecting system for processor
Inventor: KOTANO HIRONORI
IPC: G06F11/30
Filed: 1986-03-18
Abstract: PURPOSE:To early detect the runaway of a program which executes the independent two types of programs alternately and in parallel, by putting the monitor pulses into each program and deciding the occurrence of runaway in case those monitor pulses don't appear alternately for each program. CONSTITUTION:A step where an instruction to deliver pulses to outside is written is added to a program that executes the independent two types of programs alternately and in parallel by a single processor 11. When the processor 11 works normally, an FF211 and an FF221 are set and reset by a pulse P1. Then these FF221 and FF211 are set and reset by a pulse P2 appearing next and counters 31 and 32 are not counted up. If the runaway occurs to cause a program II jumps into a program I, the pulse P2 is not produced and only the pulse P1 is produced continuously. As a result, the result signal (a) is outputted continuously with the signal (b) cut off. Thus the 1st counter 31 is continuously counted up and then counted over to deliver a carry C1.

Title: Test method for magneto-optical recording medium
Inventor: UENO MASAKAZU
IPC: G11B11/105
Filed: 1990-03-09
Abstract: PURPOSE:To save manpower and time required for a test for the data recording capacity versus laser beam intensity characteristic by writing the test data while changing the laser beam intensity synchronously with the rotation of the disk and measuring the analog data of reading signals with it synchronously. CONSTITUTION:A saw-tooth wave generator circuit 20, switch 21, and oscillo scope 30 are connected to a disk recorder mounted with a mangeto-optical disk. Only by loading a software on a processor 10, the test can be carried out semiautomatically. In the test, the test data is written while changing the laser beam intensity synchronously with the rotation of the disk 1 according to the tangential position of the disk 1. Then while reading the test data synchro nously with the rotation of the disk 1, the analog data of reading signals is measured in relating to the peripheral direction of the disk 1. Thus, while the disk 1 is rotated twice, the test for the data recording capasity versus laser beam intensity characteristic is performed, which largely shortens the test time.
