Title: Context switching method for multi-task system
Inventor: SHIMOHARA AKIRA
IPC: G06F9/46
Filed: 1989-07-07
Abstract: PURPOSE:To reduce the overhead by producing an internal interruption only when a task Y uses a subregister group and switching a subcontext only when a task that used the subregister group in the preceding time is not equal to the task Y. CONSTITUTION:A main context is switched (2) after a task X is processed (1). That is, the context of a main register group of a program is saved into a context store area of the task X. Then the contents of a context store area of a task Y are loaded into the main register group. This loading operation produces no internal interruption as long as the task Y does not use the subregister group. Then the task Y is processed (3). When the task Y uses the subregister group, an internal interruption is produced by said loading operation. Then a subcontext is switched (5) as necessary (4), i.e., if the task that used the subregister group in the preceding time is not equal to the task Y. As a result, the overhead is reduced.

IPC: G01F1/68
Filed: 1988-07-18
Abstract: PURPOSE:To achieve a higher temperature characteristic by connecting a resistor with a value of below a specified percentage of a resistance value of a thermal resistance wire in series to the thermal resistance wire. CONSTITUTION:In a mass flow controller which uses a thermal flow rate sensor provided with a downstream thermal resistance wire 1 and an upstream thermal resistance wire 2 on the circumference of a fine flow tube 3, a resistor R4 with a value of below 2% of a resistance value thereof is connected in series to the resistance wires 1 and 2 on the side of R1 (or R2) of the resistor R1 and R2 thereof 1 and 2. Therefore, a resistance value increases by 2% while a temperature coefficient decreases by almost 2%. This enables external correction of the temperature coefficients of the thermal resistance wires along with a limited drift for a change in the resistance value itself and the drift is corrected by addition of an external resistor with due consideration given to this fact. In this manner, under a system of winding a thermal resistance wire, a temperature characteristic can be upgraded simply by connecting an external resistor.
