IPC: H03K21/40
Filed: 1984-03-16
Abstract: PURPOSE:To attain high-speed counting by adoting the design that a mean value between the present and preceding count values is adopted when the difference between the said mean value and the present count value is smaller than + or -1 and the present count value is adopted when the difference is larger to eliminate an error of + or -1 without increasing the resolution of a pulse transmitter. CONSTITUTION:An output pulse of a pulse oscillator 1 is counted by a prescribed sampling period by a counter 2, the count value is fetched to a controller main body 3 and fed to a control variable 4. In case of the sampling, a mean value is obtained at the 1st time while regarding the same value for the preceding time, and since the mean value is equal to the count value in this case, the value is adopted. A mean value N between the preceding count value N1 and the present count value N2 is obtained at the 2nd and succeeding operation and when the difference between the value N and the present value N2 is smaller than + or -1, the count value N is brought into count values N1, N2 after correction, and when the present mean value is larger, both the preceding and present count values are adopted. As a result, the error is halved, the instability of the control system is eliminated and the control with good response is attained.

Abstract: PURPOSE:To obtain an optical amplification receiver which has excellent temperature characteristics and a wide range of optical reception levels, by performing control of optical amplification factor with control of the driving level of an optical amplifier by making use of the fact that the amplification factor of an optical amplifier is varied by the driving level. CONSTITUTION:The output signal of an optical wave detector 5 is amplified and equalized by an electric amplifying circuit 6 and led to a terminal 7 and a control circuit 8. The circuit 8 compares the output signal level of the circuit 6 with a certain reference level and controls the driving current (optical amplification factor) supplied from a driving circuit 9 of an optical amplifier 3 so that the output signal level of the circuit 6 is always kept at the prescribed value. Therefore the output current of the circuit 9 is controlled so as to compensate the variations of the amplification factor of the amplifier 3 if caused by a change of the ambient temperature. As a result, the amplification factor of the amplifier 3 is always kept at a constant level despite the change of the ambient temperature.

Abstract: PURPOSE:To contrive to obtain uniform granules equal to or larger than 1m/m in high yield by a method in which while heating and agitating thermoplastic resin by a high speed agitator, suitable amount of cooling medium is repeatedly thrown into the resin by one or more times at the time from immediately before said resin begins to fusion bond until the granules grow relatively. CONSTITUTION:Steam is sent to the jacket 2 of a mixing tank 2, i.e. a high speed agitator, and compound material is added to the tank 1 and then is agitated and mixed, while heating said compound. When the temperature of the mixture becomes 100 deg.C, a plasticizer is thrown thereinto, and when its heating and agitating are further continued, said mixture begins to fusion bond at 116 deg.C. After the heating and agitating for the mixture have been continued at the state as it is, and the mixture-granules have grown relatively, the water of the first stage is thrown thereinto at the temperature reaching 125 deg.C. The temperature of the compound is lowered to 118 deg.C by the water thrown into, and the heating and agitating are continued. When its temperature reaches 125 deg.C again, the water of the second stage is thrown thereinto. The steam is stopped and when its cooling and rotating are continued until the temperature reaches 60 deg.C, the objective uniform granules are obtained.

Abstract: PURPOSE:To prolong the effective life of a recording element array, by varying the relative positions of a recording surface and the recording element array in a main scanning direction according to the length of a pseudo-image signal added to the end of an image signal. CONSTITUTION:The length of a pseudo-image signal added to both ends of an image signal is determined by a calculation value (x) preset on a white signal applying counter 8. The calculation value (x) is set arbitrarily and variably, by a white signal application value setting circuit 10. When the length of the pseudo-image signal is variably set, the position of a recording element array 14 in a main scanning direction is varied by a positioning circuit 16 according to the length of the pseudo-image signal, whereby a recording position on a recording surface P is maintained at a constantly fixed position. By this, it is possible to reduce variations in the characteristics of optical recording elements with time, without spoiling positional accuracy in recording, and to prolong the effective life of the recording element array 14.
