  • Patent number: 10983823
    Abstract: A computer apparatus (100) includes an OS execution unit (120), an OS-dependent interrupt processing unit (110), and an OS-independent interrupt processing unit (130). When an OS-independent interrupt (201) due to a state of a device (200) occurs, the OS-independent interrupt processing unit (130) determines whether or not to initiate a task (145). When the task (145) is to be initiated, the OS-independent interrupt processing unit (130) turns on the flag (141) and causes the OS execution unit (120) to generate an OS-dependent interrupt (202). When the OS-dependent interrupt (202) is generated, the OS-dependent interrupt processing unit (110) determines whether or not the flag (141) is on, and when the flag (141) is on, initiates the task (145) and turns off the flag (141).

  • Patent number: 5783703
    Abstract: A first embodiment of the invention relates to novel carbapenem compounds, (1R, 5S, 6S)-2-?1-(1,3-thiazolin-2-yl)azetidin-3-yl!thio-6-?(R)-1-hydroxy-ethyl!-1- methylcarbapen-2-em-3-carboxyic acid derivatives. These carbapenem compounds are represented by the following formula having a beta-coordinated methyl group introduced at the 1-position and a ?1-(1,3-thia-zolin-2-yl)azetidin-3-yl!thio group introduced at the 2-position. ##STR1## In the formula, R is hydrogen; lower alkyl group which is unsubstituted or substituted by hydroxy, lower alkoxy or lower alkoxy-lower alkoxy group; group --COOR.sup.1 (R.sup.1 is hydrogen or lower alkyl group); or group --CONR.sup.2 R.sup.3 (R.sup.2 and R.sup.3 are, independently each other, hydrogen or lower alkyl), and Y is carboxy, --COO.sup..crclbar. or protected carboxy. These compounds are useful antibiotics for prevention and treatment of bacterial infections.
