Title: Temperature sensor and temperature detector using the same
Inventor: ITO NOBUHIRO
IPC: H01B3/00
Filed: 1987-01-23
Abstract: PURPOSE:To detect temperature by providing electrodes on mutually opposite surfaces of a pyroelectric body made of a rhombohedral system titanic acid lead zirconate ceramic composite body which has a specific coefficient of pyroelectricity. CONSTITUTION:The pyroelectric body 1 is the rhombohedral system titanic acid lead zirconate ferroelectric ceramic composite body which has the maximal inflection point of the coefficient of pyroelectricity between -50 and +130 deg.C and an electrode 2 and a lead wire 3 are provided on both surfaces and covered with a well-heat- conductive insulator film 4. This temperature sensor generates a pyroelectric current as the temperature rises. Current-voltage conversion 6 and voltage amplification 10 are performed and the resulting voltage is applied to the inverted input terminal of a comparator 7. The comparator 7 inputs a reference voltage V0 from a reference voltage setting means 8 and generates its output when the output of an amplifier 10 reaches V0 to operate a driving circuit 9, thereby generating a warning. The output of a current voltage converter 6 depends upon the coefficient of pyroelectricity and a temperature gradient, but fluctuations of 2- - 3-fold temperature gradients can be removed by proper setting and the maximal inflection point temperature of the coefficient of pyroelectricity is accurately detected.

Abstract: PURPOSE:To efficiently obtain the subject compounds in high purity substantially without denaturating the compounds by treating milk whey with a hydrophobic chromatography resin, thus largely reducing the prices of the compounds which have been highly expensive food raw materials. CONSTITUTION:Milk whey is adjusted to a pH of 4.4-4.6, a protein concentration of 0.5-10%, and a Nail concentration of 1M. The adjusted milk whey is brought into contact with a hydrophobic chromatography resin and subsequently fractionated with a 0.75 Nacl aqueous solution and with a 40% (V/V) ethanol. Thus, 3-lactoglobulin (beta-Lg) is obtained from the non-adsorption fraction, and alpha- lactoalbumin(alpha-La) and lactoferrin (Lf) are obtained from the ethanol elusion fraction. Concretely, e.g. the non-adsorption fraction of the resin is desalted with a ultrafiltration module having a fractionation mol.wt. of 6K-14K to obtain the highly pure beta-Lg. Further, the ethanol elusion fraction is subjected to the removal of the ethanol, and subsequently treated with an ultrafiltration module having a fractionation mol.wt. of 50K and then with an ultrafiltration module having a fractionation mol.wt. of 60K to obtain the highly pure alpha-La and the crude Lf, respectively.
