摘要:
Disclosed is a container for the thermal analysis of cast iron that enables a reduction in the amount of tellurium used in thermal analysis. By forming a plurality of fine spaces in the interior of a base plate (12) and sidewalls (11), thermal insulating properties are maintained in the base plate (12) and the sidewalls (11) and the temperature of a sample of the cast iron melt placed in the interior of the container (1) is prevented from cooling down. As a result, even if the amount of a sample supplied for thermal analysis is reduced, the speed by which the temperature of the sample drops is suppressed, and a constant temperature is maintained by the heat from the latent heat of solidification. Accordingly, the amount of tellurium used in thermal analysis can be reduced by reducing the amount of the sample supplied for thermal analysis.

Methods for inspecting the content of structure modifying additives in the molten bath of cast iron and chilling tendency of flaky graphite cast iron by means of a thermal analyzing test and a sampling vessel to be used therefor. The method consists of the steps for: obtaining a first cooling curve of the molten bath of cast iron using a first sampling vessel, obtaining a second cooling curve of the molten bath using a second sampling vessel in which small amounts of tellurium are contained, and comparing the first cooling curve with the second cooling curve.

A method for judging the properties of molten cast iron which consists of connecting three sampling vessels with an apparatus for obtaining a cooling curve of molten cast iron, measuring a cementite eutectic temperature (TEC) of cast iron poured to the first sampling vessel to which a chilling agent is contained, measuring a eutectic freezing temperature change of molten cast iron poured to the second sampling vessel being free of any additive, measuring a graphite eutectic temperature (TEG) of molten cast iron poured to the third sampling vessel, and inspecting a relation between the cementite eutectic temperature (TEC) and the graphite eutectic temperature (TEG) within the range of the eutectic freezing temperature change of molten cast iron.

An occupying area of a digital system signal line driver circuit in an image display device is large and this hinders the miniaturization of the display device. A memory circuit and a D/A converter circuit in the signal line driver circuit are commonly used for n (“n” is a natural number equal to or larger than 2) signal lines. One horizontal scanning period is divided into n periods and the memory circuit and the D/A converter circuit each perform processing for different signal lines during each of the divided periods. Thus, all the signal lines can be driven. Therefore, the number of memory circuits and the number of D/A converter circuits in the signal line driver circuit can be reduced to one n-th in a conventional case.

An object of the present invention is to provide a milk-type food and drink including cow's milk packed in a transparent container such as a PET bottle, which does not generate off-flavor due to photoinduction even when the milk-type food and drink is a store-displaying commercial product which is apt to come under the influence of sunlight and fluorescent light. The invention relates to a milk-type food and drink packed in a transparent container which substantially shields light in the wavelength region of 550 to 720 nm, and a process for producing a milk-type food and drink, which comprises packing a milk-type food and drink in a transparent container which substantially shields light in the wavelength region of 550 to 720 nm.

There are provided: a first logic operation circuit which performs a logic operation using a high-amplitude logic signal; a transmission system having a load capacitance; and a low-voltage signal generator which is a step-down level shifter transforming an incoming high-amplitude logic signal from the first logic operation circuit to a low-amplitude logic signal having a lower amplitude than the high-amplitude logic signal for output to the transmission system. In the configuration, the first logic operation circuit operates based on a high-amplitude logic signal, and is therefore free from malfunctions and performs operations at high speed. Further, the transmission system introducing a load capacitance transmits a low-amplitude logic signal and therefore restrains increases in electric power consumption and occurrence of unnecessary radiation.

It is intended to provide a milk drink obtained by starting with a milk protein-containing powder (skim milk powder, etc.) having a seriously worsened flavor which is free from worsening in the flavor after heating and sustains a flavor comparable to a product obtained by starting with fresh milk or fermented milk alone without using such a starting material as described above. An inert gas such as nitrogen gas is bubbled into a conditioned milk liquor containing a milk protein-containing powder (for example, whole milk powder or defatted milk powder) which is obtained by starting with fresh milk or milk so as to lower the dissolved oxygen concentration in the conditioned milk liquor to 8 ppm or below. Next, the conditioned milk liquor is subjected as such to heat sterilization.
