Title: Gain control circuit
Inventor: TATEISHI HISAO
IPC: H03G3/10
Filed: 1982-06-21
Abstract: PURPOSE:To change the maximum attenuation of gain and to suppress the lowering of the maximum gain, by providing a means which controls whether or not a voltage to vary the maximum attenuation is to be applied to a differential amplifier receiving an input signal in response to a gain control signal. CONSTITUTION:In keeping the maximum gain, a voltage applied to a variable bias terminal 25 is kept higher than a voltage applied to a fixed bias terminal 24 for making a transistor (TR)26 nonconductive and making a TR27 conductive. Thus, the current value of a variable current source 30 varying the maximum attenuation does not give effect on TRs 15, 16. Further, in decreasing the gain, the voltage at the terminal 25 is made lower than the voltage at the terminal 24 so as to make the TR27 nonconductive and the TR26 conductive. Thus, the current of the variable current source 30 flows through power supply terminal 1- TR16-TR26-variable current source 30-ground, and a current, which is the sum of the current from a constant current source 21 and the variable current source 30, flows to the TR16, and the maximum attenuation of the gain is adjusted by adjusting the current value of the variable current source 30.

IPC: B22D17/22
Filed: 1986-05-12
Abstract: PURPOSE:To stably mold a molded item with high flatness by a method wherein the mold clamping force is gradually lowered during the cooling process of injection molding. CONSTITUTION:After the completion of mold closing, a solenoid pressure regulating valve 22 raises the pressure in a pressurizing side oil chamber 10, which is detected by a pressure switch 24. When the detected oil pressure reaches the predetermined value or the value which develops the necessary mold clamping force, a controller 26 holds the solenoid pressure regulating valve 22 in the state at that time. Simultaneously when the pressure switch 24 reaches the predetermined value, the timers 28, 29, 30 and 31 of the controller 26 start time counting an the injection of molten resin from a nozzle 97 in done and the dwelling process is performed. During the cooling process, the mold clamping force applied to a movable old 98 and a stationary mold 96 is stepwise lowered as time goes by. As a result, no residual strain is left in a molded item and the molded item has the form and flatness which respectively correspond to those of the cavity 99 of a mold.

Abstract: PURPOSE: To inject the fuel stably even where the measurement of the intake air amount is unstable by a method wherein a pulse signal with a constant pulse width is continuously outputted to a fuel injection valve in the case where the pulse signal varies within a certain range.  
     CONSTITUTION: Based on the signals fed from a flow rate detecting means and a speed detecting means, TP=K.u/N (where TP is the pulse width; K is a constant; u is the flow rate of intake air; and N is the engine speed) is calculated.

Abstract: PURPOSE:To confirm whether a regenerative signal value is correct or not by comparing a predictive signal value obtained by adding the value of a differential signal in the past and a transmission predictive signal value from a differential pulse encoder. CONSTITUTION:As for a partial predictive signal outputted from a predicting circuit 21 based on a signal value in the past, the information for showing the logic of a bit at every bit is modulated by a modulating circuit 16 in a prescribed frequency band.

On the other hand, a quantized differential signal 25 is added to the predictive signal 22 of the predicting circuit 22 by an adding circuit 29 and becomes a regenerative signal 31, and the information of the predictive signal value is transmitted to a decoding side. In such a manner, on the decoding side, by comparing this predictive signal value with the predictive signal value from the differential value, whether the decoded signal is correct or not can be confirmed.

Abstract: PURPOSE:To uniform the distribution and mixing ratio of exhaust recirculation gas and improve the operating property, fuel consumption as well as exhaust gas emission of the engine by a method wherein the auxiliary air is directly distributed into and supplied to at least two displacement sections by an auxiliary air distributing pipe. CONSTITUTION:Upon a low load operation, in which a suction air choking valve tends to be closed, a part of the suction air is sucked through the control valve 6 of an auxiliary air path 5 and the balance of the same is sucked through the choke valve of a throttle chamber 1.
