Title: Level converting circuit
Inventor: KITAMURA YOSHIAKI
IPC: H03K19/0175
Filed: 1991-03-15
Abstract: PURPOSE:To attain stable level conversion with less logic level fluctuation by selectively outputting one of two voltages generated by applying resistance division to a power supply voltage with two transfer gates controlled by a level before the conversion. CONSTITUTION:Resistance elements 11-13 apply resistance division to a voltage from a ground potential to a negative power supply 22 to form logic levels -0.9V, -1.7V of an emitter coupled logic circuit ECL. Transfer gates 24, 26 are controlled respectively by a voltage inputted to an input terminal 20 and the output voltage of an inverter 18 being the inverse of the input voltage. Then the gate 24 is turned on, the gate 26 is turned off and the inverse case is also satisfied. Thus, any voltage of the voltages -0.9V, -1.7V generated by the resistance division is selected to an amplifier 19. The amplifier 19 implementing full feedback outputs the same voltage as the inputted voltage. The offset of the amplifier 19 is nearly several mV by taking the power supply fluctuation into account and the effect on the fluctuation of the logic level is neglected.

Filed: 1991-03-13
Abstract: PURPOSE:To easily perform inspection by testing holding operation by feeding back the reversal value of a stored logical value to a transistor switch means changing over the data input of a latch circuit and the feedback of the holding of a memory value. CONSTITUTION:A latch circuit is constituted of transistors 1,2, inverters 3, 4, an OR gate 6 and an NAND gate 7. When the latch circuit is operated in such a state that a first test signal TESTO is set '1' and a second test signal TEST 1 is set to '1', the output of the gate 6 becomes '1' regardless of the signal output of the inverter 3 and the output of the gate 7 becomes '0'. When a clock signal CK is '0', said signal CK appears in data output Q because of the continuity of the transistor 2. When TESTO is set to '0' and TEST 1 is set to '0', the output of the gate 7 becomes '1' regardless of the output signal of the gate 6 and said signal appears in the data output Q. When data output is monitored by applying two kinds of these test signals, the cut-off trouble of the transistor 2 can be detected.

Title: Supply circuit from dc power source
Inventor: HOSAKA YOSHIAKI
IPC: H02J7/34
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently take out a current from a plurality of power sources by connecting a pair of DC power sources in parallel, connecting N-channel type MOS-FET in series to one of the DC power sources, and operating the MOS-FET, based on the voltage difference between the input terminals of both DC power sources. SOLUTION: If the voltage of an external power source (DC jack) 14 drops below the voltage of the internal power source (battery) 22, then a differential amplifier 36 outputs a high-level signal and turns on the MOS-FET 34 and power is supplied from the internal power source 22 to a load 12. In this case, a reverse current to the external power source 14 is blocked by a diode 28. If the voltage of the external power source 14 is higher than the voltage of the internal power source 22, the differential amplifier 36 outputs a low level signal and turns off the MOS-FET 34, and power is efficiently supplied to the load 12 from the external power source 14.
