  • Method for Calculating the Transfer Function from Values of Five Points of a Transient Response

    In this paper method and formulas are given for deciding a 3 rd-order transfer function from the values of five points of a transient response x (t) which is started from a steady state and ended on thsame steady state. The impulsive response of the system having this calculated 3rd-order transfer function coincides with x (t0), x (t0), x (t0+γt0), x (t0+2γt0), x (t0+3γt0) of the transient response. This method may be applicable to decide the transfer function of a element of a automatic control system by taking the ratio of 3 rd-order transfer function.

    Special Slide Rules are designed for determining frequency response characteristics of feedback com-pensated on-off type controllers.
    The output of this kind of controllers is of pulse form or of rectangular wave form with constant height. The newly designed slide rules enable to determine the pulse durations of the output signals to a sinusoidal or step input signals, provided that the feedback elements are either first order lag or second order lag. After determining the steady state output pulse train to the sinusoidal input, Fourier series, expansion of the pulse train leads to the frequency response of the controllers.

  • Process-simulator Applying Heat Transmission

    This paper presents the principle, structure and performance of a process-simulator with one input and one output. Its principle is based upon one dimensional heat transmission with a heat input and an output from thermoelectromotive forces. It principally consists of a brass bar as a heat transmission medium, distributed thermocouples as temperature sensing elements and as many potentiometers as the thermocouples. Heat which is proportional to the input function transmits through the brass bar giving thermoelectromotive force to each distributed thermocouple. These thermoelectromotive forces, after multiplied by potentiometers, are added together into an output. The step response of this simulator varys according to the potentiometer settings. The typical step responses are non-overshoot response, one-overshoot response and reverse response, etc.

    On the high frequency application of transistor chopper, the spike voltage due to chopper excitation is the main limitting factor to the drift voltage level.
    In this paper, first, linear network theory of the spike voltage is described and important characteristic of the spike area is clarified. Then the spike area and the spike waveforms are calculated by some simple models and, general expression of the spike area coLcidering load effect, filter effect, nonlinier effect of the transistor capacitance, etc. is obtained.
    In the latter of the paper, various experimental deta are shown which coincide well with the theoretical results.
    The spike area Sa and Sb are proportional to exciting voltage, load resistance and especially exciting frequency. Moreover, spike areas are also concidered to be proportional to the drift voltage of the circuit. Consequently, the upper limit of the exciting frequency is obtained.
    In the appendix, some effects of the minority carrier storage of the transistor are discussed, showing to be negligible as compered with spike effect.
