Title: Level conversion circuit
Inventor: UEMATSU TSUYOSHI
IPC: H03K19/018
Filed: 1986-11-19
Abstract: PURPOSE:To prevent the saturation of an output transistor (TR) by connecting a diode between a constant current path of a level shift stage and collectors of a phase inverting TR and the output stage TR. CONSTITUTION:In a conversion circuit comprising an ECL input stage CS, a level shift stage LS, and an output stage OP, the diode D1 is connected between a collector of the phase inverting TRQ6' and a node n4 of a constant current path where TRs Q12', Q14' of the shift stage LS and a resistor R21' are connected in series. Thus, when the TRQ6' is turned on, the potential of a node ns is decreased by the collector resistor and the TRQ6' approaches the saturation, a current flows from the node n4 to the node ns through a diode D1. Then the potential of the node n4 is decreased, the base potential is decreased and the saturation of the TRQ6' is prevented. The collector of an output TRQ9 of the output stage OP is connected to the other constant current path via diodes D2, D3 to prevent the saturation. As a result, the delay in the output is avoided without using a Schottky type TR and the leading is made steep to prevent the occurrence of the oscillation.

Abstract: PURPOSE:To eliminate erroneous observation of a filling amount at the time of observing by a sight glass and to prevent overcharging of refrigerant by providing a refrigerant oil separator, and charging the refrigerant in a state that lubricant is separated. CONSTITUTION:When refrigerant is charged by a refrigerant charger 3, an inlet tube 4 and an outlet tube 5 are connected to a refrigerant compressor 21, a valve is switched to be set to a first communicating passage 8, and then a refrigerating cycle 2 is operated. Refrigerant gas and lubricant are fed into a separator 61 of a refrigerant oil separator 6 through the tube 4, the gas and the lubricant are separated by a centrifugal force, and only the gas is returned into the cycle 2. When the valve is switched to be set to a second communicating passage 9, refrigerant to be charged in a refrigerant vessel 7 is charged in the cycle 2 through the tube 5. When it is switched to a third communicating passage 10, lubricant in a reservoir 62 is returned into the cycle 2. Accordingly, when the charging amount of the refrigerant is observed via a sight glass 28, the circulating amount of the lubricant in the cycle 2 is considerably small, so whitening of the glass 28 is prevented, and bubbles in the refrigerant can be effectively judged, and hence overcharging of the refrigerant is eliminated.

Abstract: PURPOSE:To set highly accurate level comparing voltage, by providing a level comparing circuit containing the first and second negative and positive conductive type MISFETs and the reference voltage source connected to the gate of the second MISFET through a node. CONSTITUTION:The N-channel MISFETM1 connected between a common input pin 1 and a node N3 becomes an ON-state when the voltage VP of the pin 1 exceeds the threshold value voltage VT1 of FETM1. When the reference volt age VS of a reference voltage source 31 is applied to the gate electrode of FETM2 through a node N2, the P-channel MISFETM2 connected between nodes N3, N1 becomes an ON-state only when the node voltage V3 of the node N3 is higher than the node voltage V1 of the node N1 and higher by the absolute value portion of the threthold value voltage VT2 of FETM2 than the voltage VS and a current flows to the node N1 from the pin 1. Since the node N1 is connected to the input terminal of an inverter 13, the node voltage V13 of a node N13 is reversed through the detection of the voltage V1. Hereupon, the output voltage V13 of a level comparator 30a is again reversed by an inverter 12 and the input/output voltage characteristic thereof becomes equal to node voltage V12 and a testing circuit 21 is operated.
