A bit sliced decimal adding/subtracting unit includes an 8-digit decimal adder/subtracter and an offset data generator. In the 8-digit decimal adder/subtracter, eight 1-digit decimal adder/subtracters are intercoupled so as to allow a carry to propagate from the lower order digit to the higher order digit. The offset data generator has first and second logical gates. The first logical gate detects whether or not an addition mode is specified by operation mode data. The second logical gate determines that a signal ZONE representing the format of the data to be operated represents a zone format, and that the addition mode is detected by said first logical gate. The output signal from the first logical gate is used for the first and second bits of the first 4-bit offset data. The output signal from the second logical gate is used for the 0th bit (MSB) and the third bit (LSB) of the first offset data. The output signal from the first logical gate is also used for the first and second bits of second 4-bit offset data. The 0th bit and the third bit of the second offset data are fixed at logical 0. The first offset data is supplied to the offset inputs of the adder/subtracters at the even digits (where the most significant digit is the 0th digit, and the least significant digit is the seventh digit) of the eight 1-digit decimal adder/subtracters. The second offset data is supplied to the offset inputs of the adder/subtracters at the odd number digits of the eight 1-digit decimal adder/subtracters.

The cam type time detecting mechanism of an alarm clock has a time gear wheel, an alarm gear wheel and a detecting plate, all mounted on a shaft. A hole is formed on either the alarm gear wheel or the detecting plate and a projection is formed on the other. The detecting plate is movable on the shaft in the axial direction of the shaft. The time gear wheel and the detecting plate have guiding parts respectively so that the time gear wheel, in its normal rotation, continuously pushes and turns the detecting plate. At least one of the time gear wheel, the alarm gear wheel and the detecting plate has a cam for lifting up the detecting plate if the time gear wheel and the alarm gear wheel turn either in normal and reverse directions.

A welding method for manufacturing welded structures having excellent properties to prevent the propagation of brittle fracture occurring in welded joints, characterized by the step of forming a repair weld having a greater toughness than that of a butt weld and an outer edge whose angle φ with respect to the longitudinal direction of the butt weld is not less than 10 degrees and not more than 60 degrees, by applying repair welding to a region to arrest a brittle crack in a butt-welded joint where a brittle crack is likely to propagate after removing part of the butt-welded joint, in said region, by gouging or machining.
摘要:
In executing indivisible operations to be executed without being interrupted, pseudo-store instructions PST which do not perform data writing are used to perform a check for the presence or absence in a memory of pages necessary for execution of the indivisible operations. In the event of absence of the necessary pages, the necessary pages are pre-stored in the memory. This prevents the generation of page fault interruptions during the execution of an indivisible operation, thereby enabling the indivisible operation to be implemented on a software basis. A disable interrupt instruction is executed prior to the execution of the indivisible operation as required, and data indicating an address of the disable interrupt instruction is preserved in order to return to the disable interrupt instruction. In the case where an interruption, such as a page fault interruption, which cannot be disabled even in a interrupt disabled state is generated during data processing, processing is resumed from the disable interrupt instruction after the termination of processing for the interruption or an asynchronous interruption, with reference to the address.

An automatic focusing system for a camera comprises a motor rotatable in opposite directions, a drive member driven for rotation by the motor, a distance-setting member rotatable together with the drive member to place an objective lens in an initial position and movable to a predetermined forward position, and a holding mechanism for holding the distance-setting member in the predetermined forward position. The position of the drive member is identified at each monitoring point, and a position identification signal is generated. The sequence of movement of the distance-setting member is analyzed from a starting position to the predetermined forward position. The system further provides for preventing improper holding of the distance-setting member at its initial position.
