There is provided a logic circuit causing the same delay time as a conventional logic circuit and acting as a D flip-flop circuit with a data-selecting function.A logic circuit having the circuitry shown in FIG. 6 will be described briefly. Two transmission gates TG10a (TG10b) and TG11 and two inverters IV10 and IV11 are used to define a data propagation path from an input port I1 (I2) to an output port O1. Thus, four logic gates are located along the path in the same manner as they are in a conventional D flip-flop circuit. The transmission gate TG10a (TG10b) is controlled using a NOR circuit 12a that inputs a clock CLK and a select signal /sel that is the reverse of a select signal sel (NOR circuit 12b that inputs the clock CLK and the select signal sel). The transmission gate TG11 is controlled with the clock CLK. Either of two input data items is selected based on the select signals, and then output.When a D flip-flop circuit with a data-selecting function that causes the same delay time as a conventional D flip-flop circuit is adapted to a pipeline circuit, the action of the pipeline circuit can be speeded up.

A semiconductor memory element is disclosed which can share the terminals easily among a plurality of memory elements and can pass a high current and which is strong against the noises. In order to accomplish this a control electrode is formed to cover the entirety of thin film regions connecting low-resistance regions. As a result, the element can have a small size and can store information with high density. Thus, a highly integrated, low power consumption non-volatile memory device can be realized with reduced size.

A pipe fitting capable of minimizing flow resistance, decreasing force required for connection and preventing leakage of fluid therethrough. An operating sleeve slidably mounted on a main member of a socket body is forcedly thrusted and a connecting member of a connecting plug is fitted in an internal passage of the main member while pushing away balls fitted in the main member, so that the connecting member forcedly pushes an on-off valve arranged in the main member to pivotally move it for opening it. Releasing of the operating sleeve from its thrusted position causes the balls to be fitted in an annular groove of the connecting plug, to thereby accomplish connection between the socket body and the connecting plug.
