Abstract: In an electromagnetic relay wherein a movable contact spring (9) and a stationary contact spring (10) are inserted by molding into a base block (8), the width of a portion of the movable contact spring and the stationary contact spring within the base block is made larger than that of a portion thereof outside of the base block.

Abstract: In an electromagnetic relay, a position of an electromagnet assembly (X) having a core (4), a bobbin (1), a yoke (5), a hinge spring (6), and an armature (7) relative to a base block assembly (Y) having a base block (8) and a contact spring assembly (9, 10, 11) is adjusted and fixed.

Abstract: A synchronous digital data processing system employing single-phase clock pulses comprises arithmetic and control units which are capable of completing an operation during one clock pulse period. The data processing system includes closed data paths wherein only one stage of a memory circuit capable of the same operation as a master/slave flip-flop is used as a data register in the arithmetic unit and as an address register in the control unit. In either case, during one cycle of a single-phase clock pulse, an input data is set in the memory circuit, and the output of the memory circuit is renewed in response to the input data. The output of the memory circuit is held until it is renewed in the following cycle.
