摘要： A buffer circuit with driving current adjusting function is provided which may automatically set a driving current characteristics of a buffer to the most suitable value according to a system where the driving current is to be applied. A buffer circuit with driving current adjusting function of the present invention comprises a buffer circuit which is controlled by a control signal for supplying a most appropriate driving current to a load; a load detecting circuit for detecting a phase difference between an input signal and an output signal of the buffer circuit and for outputting voltage corresponding to the phase difference, a control signal generating circuit for generating a signal which controls the driving current of the buffer circuit in response to an output signal of the load detecting circuit, the control signal controls so that the driving current of buffer circuit is increased when delay time of buffer circuit becomes long and the driving current of buffer circuit is decreased when delay time becomes short.

摘要： A master-slice semiconductor integrated circuit device includes a substrate for an input/output circuit section, which is segmented into a plurality of segments during a master processing step. In a slice processing step, slice cells are formed, using different substrate segments. Input/output circuits are formed by respective slice cells so that desired different supply voltages can be applied to input/output circuits on different substrate segments.

摘要： A semiconductor integrated circuit includes cascaded asynchronous sequential logic circuits. Scanning shift registers are provided between the asynchronous sequential circuits to permit test data to be applied to the inputs of the circuits and to latch and shift out output data provided by the circuits in response to the test data. Additional gating circuitry is provided between the scanning shift registers and the inputs of the asynchronous sequential circuits to prevent new data latched into the scanning shift register from causing the asynchronous sequential circuit connected to the scanning shift register output from changing state during testing. This same additional circuitry may be used to provide pulses of controlled width and/or timing to asynchronous sequential circuit inputs in response to externally generated gating control signals.

摘要： A method of reconstructing or reclaiming river channels which are partially filled with soft, slimy sedimentary deposits including industrial wastes which are in a semi-fluid condition or fluidized state comprising the steps of: demarcating a portion of the channel by placing a water tight wall entirely across the channel from bank to bank at an upstream and downstream location; depositing stable fill material adjacent the banks of the channel so as to displace the soft sedimentary deposits and water toward the center of the channel; and treating the displaced soft sedimentary deposit in situ beneath the overlying water so as to stabilize the entire mass.The channel may be completely reclaimed by pumping out the overlying water after the soft sedimentary deposit has been stabilized and then filling with stable material or stable material may be simply placed on the stabilized mass and the water displaced over the top of the downstream wall or over the adjacent bank.
