    摘要: A thermomechanical analyzer for efficiently measuring the dynamic viscoelasticity of a sample piece. The analyzer is provided with a function generator, a stress applier, a strain detector, an analog-to-digital converter, a memory and a Fourier transform processor. The function generator generates a sine wave signal to induce a sine wave stress-strain response in the sample piece. This response is Fourier-transformed by the processor to calculate the dynamic viscoelasticity of the sample piece.

    摘要: In a computer system, a CPU bus cycle control section receives a bus cycle request (BC-REQ) to generate a system bus cycle request (SBC-REQ) and feeds back a ready notice (READY-a) to the CPU. A system bus cycle control section performs the bus cycle control in response to the system bus cycle request (SBC-REQ) from the control section and generates a ready notice (READY-b) to the CPU bus cycle control section. The computer system includes a timer for delaying the ready notice (READY-b), a selector for selecting one of the ready notice (D'READY) delayed by the timer and the ready notice (READy-b) from the system bus cycle control section and supplies the selected ready notice to the CPU bus cycle control section and a register for holding access control information including a recovery state bit FRDY and recovery time data (RDY3-RDY0) of the timer.
