Abstract: ASYNCHRONOUS CHECKPOINTING SYSTEM FOR ERROR RECOVERY          Abstract A method of recovering from an error condition during operation of a program that is modifying a data base without corrupting the data base, wherein the program includes calls to record the progress of the operation in a table in memory.  On the occurrence of an error condition, the tables for all programs in operation are transferred to a disk.  During error recovery, the tables are returned to memory where the information stored in the respective tables is used by each active program to restore operation of the particular program to a point where the operation can be completed without corrupting the data base.  Each program is designed to interrogate its own recovery table following the occurrence of an error condition to restore operation at a point where the integrity of the data base is assured.

Abstract: Abstract of the Disclosure:           An electrical connector for electrically connecting terminal pins of a circuit package to a circuitry of another circuit board having quasi-terminal pins for elastically pre-bending pairs of spring arms of contact elements in the connector.  The connector is provided with an insulator base member for embracing the contact elements, and an insulator cover member slidably overlying the base member.  The base member has recesses for permitting the spring arm pair to elastically bend.  The cover member has penetrating holes for introducing the conductive pins into the recesses.  The quasi-terminal pins are attached to the cover member adjacent to the penetrating holes, respectively, each of which is inserted between the spring arms and are in press-contact with them.  Thus, the spring arms are pre-bent to facilitate an insertion of the terminal pin into a space between spring arms.  The circuit package is adapted to the connector so that the terminal pins are introduced into the recesses through the penetrating holes.  When the circuit package is slided along the base member, each of the terminal pins is laterally shifted to be inserted into a space between the spring arms and then each of quasi-terminal pins is shifted to go away from the spring arms.  Therefore, the terminal pins are pinched between the spring arms to thereby be electrically connected to the contact elements.  Preferably, each of the spring arms is provided with a guide leaf for guiding insertion of the quasi-terminal which is inserted thereinto.

Abstract: ABSTRACT         A digital  pattern generator which generates various kinds of digital pattern signals is disclosed.  A first memory stores an execution signal,  an area control signal and a digital pattern.   A program counter generates a first address signal in accordance with the execution signal read from the first memory and a first clock signal, and the first memory is addressed by the first address signal.  Thus, the pattern generator operates as a microprogram type  generator.   A second memory includes a plurality of memory areas each storing a digital pattern, and a capacity of each the memory area corresponds to that of the first memory.  When the second memory is addressed by a second address signal from an address counter, the pattern generator operates as a sequential type generator.   When the memory area of the second memory is selected by the area control signal read from the first memory and the selected memory area is addressed by the first address signal,  the second memory acts as an auxiliary memory of first memory.
