Abstract: A warm wave generating system includes a direct-current power supply, a frequency generator to output a variable signal wave at a predetermined frequency range, a transformer in which a primary coil through which a direct current outputted from the direct-current power supply can pass is opposed to a secondary coil through which the signal wave outputted from the frequency generator can pass, and a heating element connected to the direct-current power supply via the primary coil of the transformer. The direct current, which is modulated by the signal wave passing through the primary coil of the transformer and then through the secondary coil, is used to allow the heating element to generate heat.

Abstract: The present invention is directed to a method of preparing a biological sample for quantification which includes an element to be quantified. A volume of biological sample is collected without quantifying the volume thereof to mix with a specified volume of an aqueous solution. Absorptivity of an indicating material in the aqueous solution is measured. Absorptivity of the indicating material in the collected biological sample mixed with the specified volume of the aqueous solution is measured. Next, a dilution ratio of the biological sample is calculated using the absorptivity of the indicating material in the specified volume of the aqueous solution and the absorptivity of the indicating material in the biological sample mixed with the specified volume of the aqueous solution.

Abstract: A semiconductor integrated circuit comprises a digital-to-analogue converter for converting a digital signal into an analogue signal to output an analogue current signal, a current-to-voltage converter for converting the analogue current signal output by the digital-to-analogue converter, into an analogue voltage signal whose level has been controlled, and a filter for filtering the analogue voltage signal converted by the current-to-voltage converter. The current-to-voltage converter converts the current signal into the voltage signal in which a factor variable in accordance with manufacturing process conditions and/or environmental conditions has been corrected.

Abstract: A semiconductor device with temperature compensation functions and a temperature change detecting device which detect temperature changes accurately, without requiring extra mounting space. A sensor unit is composed of first semiconductor components (first-type resistors) having a certain temperature coefficient and second semiconductor components (second-type resistors) having a different temperature coefficient. They are located in the vicinity of a processing circuit that needs temperature compensation. Changes in the temperature of the processing circuit are detected by a temperature change detector which observes a certain property (e.g., resistance) of the first and second semiconductor components constituting the sensor unit. A temperature corrector corrects functions of the processing circuit according to the detection result provided from the temperature change detector.

Abstract: In a character reading apparatus, a slip image having three reference marks printed at three of the four predetermined corners of the slip is stored in an image buffer. The image in the image buffer is scanned to detect the three reference marks. A feed orientation of the slip is determined on the basis of the layout of the three reference marks. Data can be read on the basis of the detected three reference marks and the determined feed orientation of the slip.

The controller selectively sends a first control signal to the first lamp and a second control signal to the second lamp in accordance with whether or not a data sheet contains a pattern described in a drop-out color. The first lamp emits first light having a first wavelength characteristic in accordance with the incoming first control signal. The second lamp emits second light having a second wavelength characteristic different from the first wavelength characteristic in accordance with the incoming second control signal.
