摘要:
A control circuit uses an adjustable resistance to generate a first control signal whose amplitude varies with the setting of the resistance and a second, step-like control signal whose level changes from a first to a second level at a predetermined setting of the resistance. The variable resistance is coupled to the collector of one of a pair of transistors whose emitters are commonly connected to a reference potential. The adjustable resistance's tap, which provides the first control signal, is connected to the base of the one transistor. A collector impedance and the variable resistance are coupled between the collector circuit of the one transistor and a voltage source. An output of the impedance is connected to the base of the other transistor, whose collector provides the second control signal. As the setting of the adjustable tap increases, the first control signal and the voltage at the base of the one transistor correspondingly increase from a first toward a second amplitude until the predetermined setting is reached. Then the relative conductivities of the transistors are reversed, and the first control signal reverts to its first amplitude, while the second control signal undergoes a step-like transition. Additional increases in the setting of the adjustable resistance again raise the first control signal from its first amplitude.

An image capturing device for generating images with precise luminance gradation regardless of variability in output levels between pixels. The image capturing device consists of an image shifting means for moving an image position on a light receiving surface, a differential calculating section for calculating the difference between output levels of the same pixels before and after image position movement, a summed level calculating section for sequentially summing the difference in output level for each pixel in pixel lines arrayed in the direction of movement of the image position to calculate the summed level of each pixel, and an image generating section for generating images based on the summed levels of each pixel.

There is provided a driving circuit which is simple and has a small occupied area. A shift register circuit of the present invention includes a plurality of register circuits. Each of the register circuits includes a clocked inverter circuit and an inverter circuit. Both are connected in series with each other so that an output signal of the clocked inverter circuit becomes an input signal of the inverter circuit. Further, the register circuit includes a signal line by which an output signal of the inverter circuit is transmitted. Since a number of elements are connected to the signal line and parasitic capacitance is large, it has a high load. The shift register circuit of the present invention uses the fact that since the parasitic capacitance of the signal line is large, it has a high load.

This invention provides a semiconductor device having high operation performance and high reliability. An LDD region 707 overlapping with a gate wiring is arranged in an n-channel TFT 802 forming a driving circuit, and a TFT structure highly resistant to hot carrier injection is achieved. LDD regions 717, 718, 719 and 720 not overlapping with a gate wiring are arranged in an n-channel TFT 804 forming a pixel unit. As a result, a TFT structure having a small OFF current value is achieved. In this instance, an element belonging to the Group 15 of the Periodic Table exists in a higher concentration in the LDD region 707 than in the LDD regions 717, 718, 719 and 720.

A dehydrator 100 for separating water from a target liquid 13 includes at least two water separation membrane units 1a and 1b which are provided in series in a flow direction of the target liquid 13. The water separation membrane unit 1a on an upstream side out of the water separation membrane units 1a and 1b is connected to suction means 7 for sucking a gas phase containing water through one condenser 4, and the one condenser 4 condenses water in the gas phase and thereby separates the water. The gas phase sucked by the suction means 7 from the one condenser 4 is transferred to at least one downstream condenser 8 provided downstream of the one condenser 4, and the downstream condenser 8 condenses water in the gas phase and thereby separates the water. The water separation membrane unit 1b on a downstream side of the water separation membrane unit 1a is connected to a steam ejector 3, and the condenser 4 for condensing water in a gas phase passed through the steam ejector 3 condenses water and thereby separates the water.

A time series data analyzer includes a segment condition input section, an analysis condition input section, and an optimum condition deriving section for analyzing all segments based on the segment conditions and analysis conditions inputted in the respective input sections, under all analysis conditions by a maximum entropy method and a nonlinear least squares method. The time series data analyzer derives the optimum segment length and the optimum lag value in correspondence to selected results, and an analysis execution section executes analysis by the maximum entropy method by setting the optimum analysis conditions derived as described above. The trending of the spectrum of electroencephalogram data is used as an indicator of the state of the subject based on the findings that the spectrum of electroencephalogram data is an exponential spectrum and the gradient changes depending on the state of the subject.
