Abstract: A method for controlling an overload of a main processor by assigning to the main processor of a distributed switching system with a hierarchy structure a function of informing associated lower-level processors of an occurrence of the overload, an increase in call suppression, a decrease in call suppression and a release of the overload upon controlling the overload, and assigning to the lower-level processors a function of automatically calculating the number of calls to be processed in response to a demand of the main processor, and controlling traffic affecting the main processor on the basis of the result of the calculation, so as to maintain a stable service condition for the overload control interval.

Abstract: A method for controlling an overload in a hybrid full electronic switching system, capable of maintaining a stable service condition for an overload control interval and realizing a priority control depending on the type of call by sorting an overload occurring in the system into an overload associated with processors adapted to execute services in a centralized manner and an overload associated with processors adapted to execute same services in a distributed manner and thereby automatically calculating numbers of calls to be accepted respectively for control intervals for two kinds of overloads in different control manners. The method includes two different control procedures respectively applied to a case wherein a reduction in overload can be carried out in a processor involving the overload and a case wherein a reduction in overload can be carried out by limiting services to be executed in other processors.

Abstract: A method for controlling an overload of distributed processors of a full electronic switching system, capable of automatically calculating the number of calls to be accepted for a current interval by use of the number of calls accepted for a previous interval and the number of standby processes of a call processing program so that only the number of calls corresponding to the number of services calculated is acceptable, thereby maintaining a stable service condition for an overload control interval, and capable of realizing a priority control depending on the type of call.

Abstract: A horseshoe having a shock absorbing layer and a metal frame which are tightly coupled to each other due to protrusions and depressions. The shock absorbing layer has an arc-shaped protrusion formed at its bottom front, a plurality of uniformly spaced small protrusions formed on opposite side arms of the layer, a pair of circular protrusions downwardly formed on both ends of the layer. The metal frame has first and second protrusions downwardly longitudinally extending from its lower surface throughout its length, a center protrusion being formed between the first and second protrusions, a first depression being provided between the first and center protrusions, a second depression provided between the second and center protrusions and having a tapered shape.

Abstract: A process for preparing a transparent cosmetic material having a moisturizing effect in which lactic acid and casein hydrolysate formation are carried out simultaneously in skim milk by lactic acid bacteria and proteases and, subsequently, sterilization of the lactic acid bacteria and inactivation of the proteolytic enzyme are carried out simultaneously.
