が使用されていた。For example, a method is known in which a glass capillary is formed into a convex lens shape to enlarge the mercury thread, and a method in which the mercury thread is optically colored blue to emphasize the difference between it and the scale plate. In addition to these methods, there is a method of providing a yellow glass layer behind a capillary tube containing mercury to provide a clear contrast with the mercury thread, which appears gray to black. A yellow core thermometer is shown in FIGS. 1 to 3 as an example of such a temperature needle. 1st
The figure and Figure 2 show the flat tube (1) which is the outer tube, the yellow core (2) and the scale plate (3) inside the tube, and Figure 3 shows the yellow core material glass N (4) with a triangular enlarged section. ), a mercury-filling capillary (5) with a diameter of 30 to 40 μm that occupies a part of the capillary, and a yellow glass layer (6) along the back side of the capillary. Conventionally, the glass for this yellow glass layer has been made of soda-lime glass as a base glass, with Cd8 and 8e added as coloring components.

）が最も一般的に用いられている。It is desirable that such a yellow glass layer has a thickness of 0.11111 mm and exhibits a sufficiently saturated yellow color, and that this coloring is not affected by the atmosphere or temperature. However, in conventional yellow glass, Cd8 easily volatizes, so it melts and f;! It was affected by temperature changes during the J-shape, had poor color stability, and had the disadvantage of being prone to wood grain-like color unevenness in which yellow and milky white parts appeared alternately. Furthermore, even if the color was uniform, the glass itself was highly translucent, and temperature needles made of this glass had insufficient contrast with the mercury thread and were not easy to read. Furthermore, this yellow glass
It is necessary to consider the thermal expansion coefficient, transition point, and softening temperature in order to minimize the residual strain during welding with the thermometer fabric glass. For thermometer fabric glass, JF
iNA (2) ENA 16, known as standard thermometer glass (average coefficient of linear expansion 80-86 x 10-7/℃
) is the most commonly used.

である。It has a composition consisting of CD80.1-2%, 860-1% (excluding 0), F0.1-3%, and Cd8/S
The weight ratio of s is within the range of 10 to 100, and the average coefficient of linear expansion is 80 to 96XlO/. This yellow core thermometer is characterized by having a yellow core formed by arranging a yellow glass layer.
以下に上記組成範囲を限定した理由について説明する。The reason for limiting the above composition range will be explained below.

If it is less than 0%, the coefficient of thermal expansion will be too large, and if it exceeds 70%, the meltability of the glass will deteriorate.

ぎる。A420. has the effect of improving the chemical durability of glass, but if it is less than 3%, it has no effect, and if it exceeds 10%, the meltability deteriorates. When N a 20 is less than 7%, the thermal expansion coefficient is smaller than the above range, and when it exceeds 918%, the thermal expansion coefficient becomes larger than the above range. K2O has the effect of improving the meltability of glass, but if it is less than 1%, it has no effect, and if it exceeds 5%, the coefficient of thermal expansion is too large.

と８ｅ添加による上記効果が得られない。B2O3 has the effect of improving chemical durability and melting properties, but if each is less than the above-mentioned lower limit, the meltability of the glass deteriorates, and if it exceeds the above-mentioned upper limit, the chemical durability deteriorates. CdS is added as a coloring agent and is an essential component to give it a yellow color, but if it is less than 0.1%, the glass will turn blue-green and a new color cannot be obtained, and if it is added in excess of 2%, it will not volatilize. It does not remain in Ciaras. The addition of 8e adds a reddish tinge to the color tone, making the yellow color saturation caused by Cd8 more vivid, but if it exceeds 1%, the desired coloration cannot be obtained, with a strong red tinge. F acts as an emulsifier and has the effect of reducing the transmittance of the glass and stabilizing the color tone, but if it is less than 0.1%, it has no effect and causes color unevenness in the glass, and if it is added in excess of 3- Even if it evaporates, it will not remain in Ciaras. In addition, the ratio of Cd8 to 8e is an important factor in determining the color tone of the glass.If the weight ratio of Cd8/8a is less than 10, the red color will be too strong, and if it exceeds 100, the above effects due to the addition of 8e will be affected. is not obtained.

トが高く、水銀糸の高さ位置検出が容易である。In addition, the thermometer in which the colored layer made of yellow glass is installed behind the capillary tube filled with mercury has a yellow glass layer with a uniform color tone and sufficient saturation, and has a high contrast with the mercury thread. It is easy to detect the height position of the mercury thread.

が低いガラスはど乳濁度が高いといえる。After melting for 2 hours at a temperature of 1,350 to 1,400 degrees Celsius,
Nine samples were taken from nine pieces that were poured into molds and slowly cooled. This was polished into a glass plate with a thickness of 0.5-nm and the wavelength was 700 nm.
The transmittance was measured. In milky glass, long wavelength light is more affected by scattering than short wavelength light.
Easy to penetrate. Therefore, it can be said that a glass with a low transmittance at a wavelength of 700 fim has a high emulsion.

分となって、水銀糸の嶌さが確認しにくくなる。As a guideline for determining emulsion, if the transmittance exceeds 80%, the glass will become more transparent, and when molded into a thermometer, the back of the yellow glass layer will be transparent and the contrast with the mercury thread will be insufficient. , it becomes difficult to see the mercury thread.

着しても残留歪は小さい。In the glass of Conventional Example A5, the yellow part and the milky white part appear as wood grain-like color unevenness, and the overall color tone is pale and the transmittance is high. On the other hand, all the glasses of Examples according to the present invention had a transmittance of 80% or less at 700 nm, had no color unevenness, and exhibited a bright yellow color. Furthermore, since it has a coefficient of thermal expansion similar to that of ENA 16I glass, residual strain is small even when welded with ENA 16I.
