摘要:
In a portable personal computer in which high-exothermic devices are mounted within a flat case equipped with an input unit, the and in which a surface temperature of the exothermic devices and the input unit is cooled down to or below a predetermined temperature. A first space is created between the back of a keyboard operating section and an electronic circuit board 3, the electronic circuit board 3 is installed so that the face thereof on which the high-exothermic devices are mounted faces away from the back of the keyboard, a second space is created between the electronic circuit board 3 and an electronic circuit board 2, and a fan 4 is installed inside the case so that cooling air flows from the first space to the second space. A flow path for circulating outside air into the case via an air intake hole 8 is constructed on the wall of the input device operating section.

It is an object of the invention to provide a cooler of an electronic apparatus capable of keeping semiconductor chips at a low temperature without care of condensation and which is excellent in compactness. To achieve the above object, the present invention proposes an electronic apparatus in which a heating region is built in the multilayered wiring substrate of the semiconductor package or module on the side near to the input/output pins, the semiconductor package or module and the cooler mounted on the package or module are placed in a moisture proof case, a heat insulating material is filled in the gaps between the moisture proof case, semiconductor package or module and cooler, and a heater is provided on the outer periphery of the heat insulating material.

A slot accessing method in an object-oriented expert system, wherein data, which is indicative of necessity or non-necessity of re-computation of a slot value and which is created according to a dynamic dependency between a reference slot and a reference slot, is set in a reference slot of an object having a reference rule. When the re-computation is necessary, a flat "T" indicative of the effect is set, whereas when the re-computation is unnecessary, a flat "NIL" indicative of the effect is set. When the value of a slot of an object having a reference slot as its slot value is changed, it is judged whether or not it is necessary to re-compute the slot value of the corresponding reference slot on the basis of data that is indicative of necessity or non-necessity of re-computation of the slot value and that is set in the corresponding reference slot. If the flag "NIL" is set in the corresponding reference slot, then no re-computation is carried out for the slot value.
