This technology relates to a communication apparatus and a communication method adapted to improve the deterioration of communication performance due to variations in parts, for example. A test signal generating section generates a predetermined test signal. A detecting section detects, given a received test signal obtained by a transmitting and receiving section upon receipt of the test signal, an influence parameter affecting the intensity of an active load modulation signal that combines a transmission carrier with a synchronizing signal synchronized with a received signal obtained upon receipt of the transmission carrier. A controlling section controls the intensity of the active load modulation signal in accordance with the influence parameter. This technology applies to cases where short-range wireless communication is performed using magnetic fields.

A method for specifically quantifying HDL cholesterol in which cholesterol in lipoproteins other than HDL is erased in the first step, and HDL cholesterol is specifically quantified in the second step, by which accurate values can be obtained even in measurements of abnormal samples such as disorder of lipid metabolism and lipoprotein abnormality, is disclosed. The method for quantifying cholesterol in high density lipoprotein according to the present invention comprises a first step of erasing cholesterol in lipoproteins other than high density lipoprotein by treating a test sample with cholesterol esterase and cholesterol oxidase in the absence of a surfactant which acts on high density lipoprotein and removing generated hydrogen peroxide; and a second step of adding a surfactant which specifically acts on high density lipoprotein to the product of said first step and quantifying hydrogen peroxide generated from cholesterol in high density lipoprotein by actions of cholesterol esterase and cholesterol oxidase. As the cholesterol oxidase used in the first step, one having a molecular weight of not more than 60 kilodaltons is used.

Disclosed is an agent for inhibiting decrease in measured values in immunoassays, which may reduce the influences by interfering substances in a test sample so as to promote the accuracy of the immunoassays, as well as an immunoassay and a reagent for immunoassays using the same, with which the decrease in the measured values due to the interfering substances is reduced. The agent for inhibiting decrease in measured values in immunoassays, caused by interfering substances, is an ionic surfactant having a molecular weight of 1000 to 100,000, the agent being a polymer in which a hydrophobic cyclic monomer(s) having an ionic functional group(s) is(are) polymerized.

The present invention is intended to provide a method for simultaneously measuring cholesterol in low density lipoprotein and total cholesterol as test components in blood. Specifically, a method is used for simultaneously measuring cholesterol in low density lipoprotein and total cholesterol in a biological sample, whereby cholesterol in low density lipoprotein and total cholesterol in a biological sample are quantified with a single measurement.

The present invention relates to a process for secretory production of a foreign protein, in particular, transglutaminase by a coryneform bacterium. According to the present invention, a process is provided for the secretory production of a foreign protein, in particular, transglutaminase, by making a coryneform bacterium to produce an industrially useful foreign protein, in particular, transglutaminase and efficiently release the product extracellularly (i.e., secretory production). An intended foreign protein, in particular, transglutaminase, is produced by using an expression construct wherein the gene sequence of the intended foreign protein containing the pro-structure part, in particular, pro-transglutaminase gene sequence, is ligated to the downstream of a sequence encoding the signal peptide region from a coryneform bacterium, introducing this expressional genetic construct into a coryneform bacterium, culturing the thus transformed coryneform bacterium, and treating the extracellularly released protein with a protease, etc. to cleave and eliminate the pro-part.

Provided is a method of stabilizing a reagent that allows simultaneous quantification of LDL cholesterol and total cholesterol by a single measurement by suppressing spontaneous color development thereof. A method of quantification for cholesterol in low density lipoprotein and total cholesterol in a biological sample by the single measurement comprises a first step of treating lipoproteins other than low density lipoprotein in the biological sample to generate hydrogen peroxide and a second step of converting the hydrogen peroxide obtained in the first step to a quinone dye and treating remaining low density lipoprotein and converting generated hydrogen peroxide to the quinone dye, where the quinone dye is not formed in the first step, and cholesterol in low density lipoprotein and total cholesterol are quantified from the amount of the quinone dye formed in the second step by the single measurement.

A temperature-compensated crystal oscillator including an oscillation circuit which includes an oscillator, a temperature detector, a voltage variable capacitance element coupled to an oscillation loop of the oscillation circuit, and a temperature compensation circuit. The temperature compensation circuit is configured to apply a compensation voltage to the voltage variable capacitance element to compensate a temperature change in response to temperature data detected by the temperature detector. The temperature compensation circuit has a plurality of correction point data. The respective correction point data is set in advance for each divided temperature zone, selects a first correction point data in a lower temperature zone and a second correction point data in a higher temperature zone, as compared with the detected temperature data, performs an interpolation between the first and second correction point data by a weighted averaged first-order interpolation, and generates the compensation voltage.
