Title: Vibration screening method and device therefor
Inventor: MAEKAWA HIROAKI
IPC: B07B1/32
Filed: 1995-04-04
Abstract: PURPOSE: To do screening work while effectively preventing clogging of a screen net even for a material to be screened such as that in which wet coal or the like coexists with dry coal or the like. CONSTITUTION: In the case where the amplitude detected by a vibration meter 9 is smaller than the reference one, a controller 10 controls the frequency of a vibrator 8 by gradually reducing the frequency of the vibrator 8 so that a body to be vibrated consisting of a screen 1 and coal 4 can be vibrated near its resonance point. In the case the frequency of the vibrator 8 is gradually reduced and reaches the lower limit one, after that, it is controlledso that it can be gradually increased. Thus vibration is applied by the vibrator 8 following up the change in natural frequency of the body to be vibrated, and the body to be vibrated is always, continuously and greatly vibrated near its resonance point to perform screening.

Title: Method for preventing incorrect accessing of memory
Inventor: TAKITA MASATOSHI
IPC: G06F9/46
Filed: 1983-05-10
Abstract: PURPOSE:To detect and prevent incorrect accessing to a main memory device by fixing previously access information regulating an area of the main memory device to be accessed by a task and detecting the case that the memory access of an instruction exceeds the prescribed area of the main memory device at the working of the task. CONSTITUTION:A program P1 is started through an operating system (OS) and the prescribed area Z of the main memory 2 is accessed. At the start of the P1, the OS applies the start address SAD of the prescribed area Z which is a previously registered transaction area TR for the P1 and its size SIZ to a register of the P1. The P1 discriminates whether the area data SAD, SID specified at the head of the program are sufficient or not as the self-area data. In case of insufficient data, the P1 informs the discriminated result and ends without the processing of execution. Thus, incorrect accessing is previously prevented. When the transaction area is sufficient, the P1 advances to normal processing.
