Title: Sense circuit
Inventor: JINBO TOSHIKATSU
IPC: G11C7/06
Filed: 1988-02-19
Abstract: PURPOSE:To improve the reliability of a sense circuit by using two MOSFETs whose threshold voltages are different in parallel, charging up the parasitic capacity of a column line at high speed, enabling the high-speed read of data and making the influence of power source noise to be hardly received. CONSTITUTION:Since both of the two MOS transistors M12 and M13 being connected in parallel turn ON at the same time and supply electric current when a digit line whose charge is not accumulated is started to be charged, the high-speed charge up almost equal to the case that a gate width is made to be wide can be made possible. Besides, since the threshold voltages of the transistors M12 and M13 are different, the transistors are hardly to turn ON at the same time. Due to that, in the state that the digit line is pulled up and the transistors M12 and M13 are in an OFF state, the power source noise occurs to an inverter. As the result of that, gate voltage does not reach gate voltage which a non-write memory element is detected and read data is not inverted. Thus, the reliability of the circuit can be improved.

Abstract: PURPOSE: To obtain a method for detecting the output current of an inverter highly accurately. CONSTITUTION: In the method for detecting the output of an inverter while eliminating the offset amount from a detected output, output current from an operating inverter is converted through a current/voltage converter 1 into a voltage which is then fed to a DC component detector 2 for removing the AC component from the output voltage to detect the DC component. The DC component is employed, as an offset amount, in the correction of output voltage from the current/voltage converter 1 and the output current of inverter is determined based on the corrected output voltage.

Title: Terminal network controller
Inventor: OISHI YOSHIKATSU
IPC: H04M11/00
Filed: 1993-02-26
Abstract: PURPOSE:To normally get an incoming call even when plural telephone sets are connected with the same telephone line. CONSTITUTION:When a polarity inversion occurs at a telephone line 1, a control part 20 terminates the telephone line by a first impedance matching part 3, and controls a gain switching part 19 in order to increase the gain of a receiving amplifier 5. That is, even when the impedance of the first impedance matching part 3 is increased, the level of a signal inputted to a signal receiving part at the time of a no-ringing incoming call is set within the dynamic range of a signal receiving part 6, and the no-ringing incoming call can be normally attained. Also, the impedance of the first impedance matching part 3 can be increased, and even when an incoming signal from the telephone line to the telephone set arrives, currents flowing from the telephone line into a terminal network controller 18 can be reduced. Thus, even at the time of connecting the plural terminal network controllers with the same telephone line in parallel, the erroneous judgement of an off-hook at a switchboard side can be prevented.
