Title: Task execution control method and operating system
Inventor: CARMON DONALD EDWARD
IPC: G06F9/46
Filed: 1992-12-26
Granted: 1996-04-20
Abstract: An operating system for scheduling execution of a random set of periodically recurring hard, real-time tasks encountered in multi-media computer system applications and which is useful in a multi-tasking computer operating environment. Periodically recurring computer tasks having relatively short execution periods for which execution results are absolutely required in hard, real-time environments such as multi-media systems, create a significant task scheduling overhead reducing the available processor resource. Overhead processing at task invocation is eliminated in the invention by placing all active recurrent tasks in an execution queue, regardless of the task's current state of activity and by reprioritizing the order of execution of the tasks in the queue whenever a given task execution is completed. Measured by reduction in task scheduling overhead consumed by the processor in scheduling the tasks, this achieves a 50-100% improvement over conventional scheduling and operating systems. <IMAGE>

The conditions of plating are that: (a) the plating bath is of chloride system, (b) the pH of plating solution is 3 to 7, (c) the temperature of plating bath is 40 to 60deg.C, (d) the concentration of zinc chloride is 100 to 150g/L, and/or (e) the added conductive aiders are potassium chloride and ammonium chloride, and/or (f) the concentration of aiders is up to 100g/L, and (g) the degree of preferred gradient in the zinc base plane of the highest atomic density is over 6.

Abstract: A pizza toppings disk (10), a method and apparatus for making said disk and a pizza using a pizza toppings disk are disclosed. A pizza toppings disk is made by combining cheese with pizza toppings (18) into a layer (14) that is shaped to be placed on a pizza shell (26). The cheese and pizza toppings are fused together to form a pizza toppings disk that may be stored for subsequent use in assembling a pizza. The apparatus includes a conveyor means for transporting forming surfaces, and a plurality of depositing means for depositing onto forming surfaces cheese and pizza toppings. A fusing means is also included which fuses the quantity of chees and pizza toppings to form a pizza toppings disk. In making a pizza in accordance with the present invention a pizza toppings disk is placed on an uncooked pizza shell which are then baked to produce a cooked pizza (28).
