A CMOS logical circuit comprises two electric current paths each of which has circuits consisting of n-type and p-type transistors. In a circuit consisting of n-type or p-type transistors, one electric current path is provided with a circuit having the same construction as that of a circuit having an n-type transistor of a CMOS logical circuit outputting a logical operation result similar to that of this logical circuit, and the other electric current path is provided with a circuit having the same construction as that of a circuit having a p-type transistor of the CMOS logical circuit outputting a logical operation result similar to that of this logical circuit. In another circuit consisting of the other channel type, a gate electrode of the transistor provided on the one electric current path and that of the transistor provided on the other electric current path are connected to drain electrodes of the counterparts. According to the construction, the amplitude of an input signal can be made smaller than a supply voltage of the logical circuit.

A food objective for extraction and/or squeezing is charged into a colloid mill or a twin-screw extruder; immediately after and/or while milling, a low-temperature solvent (for example, water or milk of from −3 to 50° C.) is added; and after treating the food using the extruder, grounds are removed to produce an extract and/or a squeezed liquid. After milling objective foods, for example, a single product or a combination of foods such as coffee, green tea, black tea, herb tea, wild grass tea, Chinese medical tea, cocoa, vanilla, fruit, and vegetable, extraction and/or squeezing can be rapidly and extremely efficiently carried out at a low temperature, which is appropriate for the mass and continuous production. Furthermore, in comparison with the conventional employed extraction and/or squeezing methods such as a low-temperature extraction method which leads to deterioration in flavor due to oxidation after milling, etc. and requires a long time, the present invention brings effects extremely advantageous from the viewpoints of enhancement of flavor and economy. For example, in tea based drinks, a useful component suspends, whereby a vivid color tone inherent to each tea is kept over a long time.

In a shift register provided with flip-flops that operate in synchronism with a clock signal, and a switching means, which is opened and closed in response to an output of the preceding stage of each of the flip-flops, is installed. The clock signal is selectively inputted by the switching means, and the selected clock signal is inverted and used as a shift register output from each of the stages. An output pulse having the same width as the pulse of the clock signal is generated.

A display panel drive circuit and a display panel are provided which are simple in structure but free from initial failure leading to impossibility to perform scanning. The display panel drive circuit of the present invention is structured such that thin film transistors constituting a signal input circuit connected to a circuit outside the display panel are formed in a structure having a dielectric breakdown strength higher than those of thin film transistors constituting other circuits. Specifically, countermeasures are taken by transistor formation in multi-gate structure, gate width broadening, resistance insertion between an input terminal and a transistor or the like. In the present invention, the circuit to which signals are externally inputted or thin film transistors of the same circuit is structured to withstand high voltage, thereby preventing the transistors from being deteriorated by high voltage and occurrence of initial failure while being simple in structure.

A digital-to-analog converter includes a first converter stage 1 for converting the m most significant bits of a k bit input signal to upper and lower voltage limits VL and VH by selecting the appropriate low impedance reference voltages. A second converter stage 2 performs a linear conversion of the n least significant bits of the k bit input within the voltage range defined by the voltage limits VL and VH. A precharging circuit including switches SW1 and SW2 disconnects the stage 2 from the load CLOAD, which is charged to the voltage limit VL during the precharge phase. The load is subsequently disconnected from the voltage limit VL and connected to the output of the stage 2 to complete charging of the load CLOAD to the converter output voltage.

The source followers comprise the transistors M1 and M2 and the transistors M3 and M4. Differential inputs IN and !IN are connected to the gates of the transistors M2 and M4. A bias voltage is supplied to the gate of the transistor M1 from a node B to which the drain of the transistor M3 and the source of the transistor M4 are connected. Similarly, a bias voltage is supplied to the gate of the transistor M3 from a node A to which the drain of the transistor M1 and the source of the transistor M2 are connected.

A matrix-type image display device of the present invention is arranged such that image data are selectively applied to pixels arranged in a matrix form through scanning signal lines and data signal lines, and the image data are stored therein, wherein a high potential of a sampling pulse 0V/5V to be output from a logic circuit is shifted to 10 V, and a low potential thereof is shifted to −8 V respectively by first and second level shifters. As a result, a difference between an input signal level from an external circuit such as a control circuit, an image signal processing circuit, etc., and an actual driving signal level of each pixel can be absorbed. Therefore, an additional structure such as an interface circuit, etc., is not needed between the external circuit and the scanning signal line driving circuit, thereby enabling a low cost and a low power consumption.

A voltage level shifter comprises complementary transistors T1, T2 connected between a supply line vdd and an inverting input !IN. The gate of the transistor T1 is connected to a direct signal input IN whereas the gate of the transistor T2 receives a shifted version of the direct input signal from a source-follower comprising the transistors T3 and T4. The level shifter may also be embodied as a differential cross-coupled sense amplifier with the sources of the drain load transistors being crossed coupled to the differential inputs.
