Inventor: NEGISHI KATSUHIDE
IPC: G01H15/00
Filed: 1979-04-05
Abstract: PURPOSE: To rapidly perform the measurement of high accuracy by obtaining the crest value of the amplitude of every one frequency of the amplitude level difference of every half frequency.  
     CONSTITUTION: A display device 7 and keyboard 8 are connected via extension memory 6 and interface 6 to a control circuit 5 including a microprocessor CPU. On the other hand, a printer 11, cassette 12, AD converter 17, voltage divider 14 and input terminals 13 of outputs of a vibration detector, temperature detector and timer are connected by way of an interface circuit 10. As a result of this, the free damping vibrations fetched as electric analog signal are sampled at the constant interval sufficiently narrow as compared to their period. After these are quantized and digitized, the amplitude crest value and period of the vibrations are calculated, and their logarithmic dampingg factor is obtained from the previous amplitude crest value and the amplitude crest value of this time and the modulus of rigidity is obtained from the square relation of the period. These are nemerically displayed or plotted by the printer 11.

Abstract: PURPOSE:To improve accuracy and to accelerate speed in an LSI with high integration and low voltage by impressing a bias voltage to the gate of a transis tor for dividing potential in the first push-pull circuit to form the current ampli fier circuit of a reference current amplifier circuit and connecting the output end of the current amplifier circuit to the bias circuit of the second push-pull circuit. CONSTITUTION:Voltage difference between an input and an output is converted to a current through the transistor of a first complementary push-pull circuit 1 and by an amplified current in proportion to the converted current, a second complementary push-pull circuit 3 is driven. Therefore, while there is the voltage difference between the input and the output, the driving ability of the push-pull circuit 3 is improved and charging/discharging is exerted upon load capacity at high speed. Then, even in that case, the driving ability can be made the same for charging and discharging. Thus, a voltage supply circuit can be formed to be stably operated at high speed even by low voltage.
