摘要:
The invention relates to a manufacturing apparatus which comprises moving means which continuously moves the works that are transferred along a frame chute, and detector means which detects at least a portion of the work that is moved. The moving means is controlled by kind-of-work data and by a work position signal from the detector means, and the work is set to a predetermined position. Hence, even a work of a different kind can be set to an optimum bonding position without the need of exchanging the unit, making it possible to perform the operation fully automatically and to meet general purposes.Further, provision is made of means which moves the frame chute in a direction at right angles with the direction in which the work is moved, so that even that work that has different widths and shapes in the widthwise direction can be placed in position and subjected to the bonding fully automatically.The detector means can be provided not only at the bonding position but also at a position on the upstream side having a relation relative to the bonding position.The invention can be adapted particularly effectively to a wire bonder and a pellet bonder.

In a one-chip high density arithmetic control unit capable of prefetching user's instructions from main memory, an arithmetic logic unit (ALU) subtracts the contents of a location counter holding the address of the next instruction to be executed, from the contents of a memory address register holding an address into which data will be written. The difference is fed through the gates connected to the ALU for determining whether or not prefetched instructions will have to be refetched. An address matching mechanism provided outside the one-chip arithmetic control unit includes a comparator for comparing memory addresses to a preset execution stop address. The output signal of the comparator is stored in a memory section which is provided to correspond to the prefetched instruction buffer, and when an instruction stored in the prefetched instruction buffer is transferred to an instruction register, the signal stored in the corresponding memory section is also read out and used to determine whether to stop execution. Further, whenever access is made to main memory a signal indicating whether the access is legal is externally generated and may be stored in a second memory section. Like the address matching signal, this signal is read out when the corresponding instruction from the prefetched instruction buffer is transferred to the instruction register. An illegal address interruption is produced when this signal indicates that the address was illegal.

A microprogrammed control system comprises: a memory for storing a microprogram programmed with microinstructions; a memory for storing microinstructions for branching microinstruction; an address register for storing the address of the microinstruction to be next executed; and a microinstruction register for storing the microinstruction to be executed. The program operation of the microprogrammed control system depends on whether the micro-instruction stored in the microinstruction register is the branching one or not. In the case of non-branching microinstruction, the operation of ordinary microinstructions is executed. In the case of branching microinstruction, a special operation is executed for making the operation of the branching microinstruction equivalent to that of the ordinary microinstruction.

A microprogrammed LSI microprocessor comprises a read only memory (ROM) for storing therein microprograms and a decode table for the operation code of macroinstructions, and an arithmetic logic control section constructed into a one package of LSI circuit. The arithmetic logic control section is constructed into a circuit arrangement which, on the assumption that the operation code of macroinstructions be an address, sets the starting address of a corresponding macroinstruction read from the ROM in a location counter, reads from the ROM a microinstruction corresponding to the starting address set in the location counter to set this microinstruction in a microinstruction register, and arithmetically executes the microinstruction stored in the microinstruction register.

A method of automated theorem proving for information processing which can be highly efficient, irrespective of the set of clauses to be dealt with. The method includes the steps of: transforming the statement and the set of knowledge into expressions in terms of elements of a module; constructing a linear equation with the elements of the module as coefficients and the elements of a ring of scalars of the module as unknowns; checking the existence of a non-negative solution to the linear equation; and determining that the statement is provable when the non-negative solution exist, and not provable otherwise.
