Abstract: PURPOSE: A hydraulic pumping apparatus is provided to simplify the structure of the pump and lengthen the lifespan of the pump while reducing parts count and noise. CONSTITUTION: An apparatus comprises an electric motor(20) and a hydraulic pump(30) coupled coaxially within a housing(10). A single shaft(31) penetrates the center of a rotor(21) of the electric motor, and a plurality of cylinder chambers(32) are arranged outside the single shaft to be coplanar with a vertical section area of the single shaft, to thereby allow the rotor of the electric motor to be used as a part of the electric motor. A check valve(40) is arranged on an oil outlet port of the hydraulic pump, so as to prevent the hydraulic pump from being rotated in reverse direction due to inertia force upon stopping of an actuator. A flow channel is formed at the oil outlet port of the hydraulic pump, and a safety valve(50) is installed at the flow channel. Thus, the oil discharged from the hydraulic pump is drained when the hydraulic pump is overloaded, to thereby protect the electric motor and the hydraulic pump from overload.

Abstract: PURPOSE: A common voltage stabilizing circuit using clamping circuit fixes a fluctuating common voltage appropriately to stabilize the common voltage. CONSTITUTION: A capacitor(C1) filters a common voltage(Vcom1) to a common voltage(Vcom2). The common voltage(Vcom2) is clamped by the amplitude of voltage of a resistor(R1). A comparator(COM) compares a voltage of the resistor(R1) inputted from a converting terminal with a reference voltage(Vref) for determining the path of a current flowing through the resistor(R1). A diode(D2) is turned-off and a diode(D1) is turned-on due to the high level signal outputted from the comparator(COM) when the reference voltage(Vref) is larger than the voltage of the resistor(R1). At this time, the current flows through the resistor(R1), the comparator(COM) and the diode(D1). The common voltage(Vcom2) is as clamped as the potential of the reference voltage(Vref). On the other hand, the comparator(COM) outputs the low level signal when the voltage of the resistor(R1) is larger than the reference voltage(Vref). At this time, the current flows through the resistor(R1) and the diodes(D2,D1). The voltage variation of the capacitor(C1) becomes the common voltage(Vcom2).

Abstract: PURPOSE: A thermostatic system of an air conditioner is provided to adjust temperature automatically by controlling an air conditioner depending on detected temperature of a temperature sensor. CONSTITUTION: An air conditioner controller(2) operates an air conditioner(6) when a user operates a start switch(1) having set reference indoor temperature. The air conditioner is run and an operator(3) operates sensing values of each sensor(4) wit set temperatures. A total signal therefrom is fed to the air conditioner controller. Thereby, the air conditioner is run normally. The plural sensors have different temperatures gradually. When the operator obtains the new temperature, a compensating temperature estimator(5) decides whether indoor temperature is met with target temperature. If so, the air conditioner is run regularly. Otherwise, the operator changes the value by increasing 1deg.C per minute if difference between the indoor temperature and the target temperature is higher than 3deg.C. The air conditioner is controlled until the changed value becomes proper. Therefore, temperature is automatically adjusted by the estimated value.

A low level signal of the first NAND gate(21) turns on the first PMOS transistor(P21), and a source voltage(Vcc) is supplied with the first node(Q21) through the first PMOS transistor(P21). The source voltage(Vcc) is divided by the first NMOS transistor and the second NMOS transistor(N21,N22). For this reason, the potential of the first node(Q21) reaches to dropped potential as much as threshold voltage of the first NMOS transistor and the second NMOS transistor(N21,N22). The third NMOS transistor(N23) is turned on by the potential of the first node(Q21), and the source voltage(Vcc) is supplied with the second node(Q22). After this, the source voltage supplied with the second node(Q22) is dropped to a fixed voltage by the turned on fourth NMOS transistor(N24) and the fifth NMOS transistor(N25). The source voltage(Vcc) is supplied with the second node(Q22) sustaining fixed potential through the second NMOS transistor(Q22) which is turned on, and the second node(Q22) sustains higher potential than the source voltage(Vcc). A path is formed by the turned on sixth NMOS transistor(N26) and the CAM cell. At this time, the sixth NMOS transistor(N26) is turned on by the sensing signal(CAMSEL) of high level. The potential of the second node(Q22) is in a high state on the occasion of the programmed CAM cell, and is in a low state on the occasion of the removed CAM cell.
