た。The Applicant of Jōmei Giken first focused sunlight using a lens or the like and introduced it into a light guide, and transmitted the sunlight to any desired location through the guide for illumination or other purposes. Various collection devices were proposed. Furthermore, in order to protect the lens from wind, rain, dust, etc., it has also been proposed to house the sunlight collecting device in a transparent capsule.

意所望の箇所へ伝達されるようになっている。FIG. 4 is a diagram showing an example of a sunlight collecting device previously proposed by the applicant. In the figure, 1 is a cylindrical base, 2 is a transparent dome-shaped head, and these A capsule 3 for a collecting device is constituted, and in a state of use, a sunlight collecting device 5 is accommodated in the capsule as shown. The solar light collecting device has the following features:1. As is well known, a large number of lenses 6 are provided, and sunlight focused by the lenses is introduced into the light guide cable and transmitted to any desired location through the guide cable.

あった。Therefore, in the solar collector device as described above, conventionally,
The above-mentioned transparent capsule was made of acrylic, but when used for many years, there was a problem in that the acrylic surface became scratched and the light transmittance decreased. In order to solve these problems, it was considered to cover the acrylic surface with a fluorine coating (film), but it was extremely difficult to uniformly coat the surface of the spherical body with a fluorine film without unevenness.

少することができる。FIG. 5 is a block diagram for explaining an example of the transparent capsule manufacturing method previously proposed by the present applicant. In the figure, 10 indicates a transparent acrylic disc 11 and a A disc made of a fluorine film 12 coated by vapor deposition, one layer of coating, or any other arbitrary means, the disc 10
The periphery of the cylindrical container 20 is hermetically secured to the upper end of the cylindrical container 20 by any desired means. Thus, acrylic can be spread a desired amount at a temperature slightly lower than its melting point, while fluorine film has about three times the spreadability.
Moreover, its melting point is considerably higher than that of acrylic, therefore, as described above, the disk 10 is placed on top of the container 2o with the fluorine film 1.
After the acrylic disk 11 is airtightly attached with the coated side facing upward, when heated air is applied to the container 20 under pressure, the acrylic disk 11 deforms into a spherical shape as shown in the figure, and a fluorine film is formed on the outer surface of the acrylic disk 11. 12 is coated without unevenness, that is, optically uniformly. The air pressure applied at this time varies depending on the size of the capsule, the thickness of the acrylic plate, etc., but if a particularly large pressure is required, applying negative pressure to the side covered with fluorine film will cause the acrylic plate side to The air pressure applied to the air can be reduced.
しかしながら、上記透明カプセルは、第４図に示すよう

When manufacturing a semicircular transparent capsule as described above,
For example, as shown in Fig. 5, blow molding is performed by blowing heated and pressurized air, but in this case, it is difficult to make the entire area approximately uniform, and the area near the flange is thick and the area near the top is unavoidably thick. It becomes thinner, and as a result, the refractive index of light differs in each part.
効率のよい太陽光収集ができなかった。Efficient solar collection was not possible.

In particular, the present invention aims to provide a transparent capsule that has substantially the same thickness throughout and is seamless, and a method for manufacturing the same.

成されている。Structure FIG. 1 is a sectional view showing an embodiment of a transparent capsule according to the present invention, and in the figure, 30 is a transparent capsule according to the present invention,
The capsule 30 consists of a substantially hemispherical portion 30a at the top, and a cylindrical portion 30b that is integral with the hemispherical portion 30a following the hemispherical portion 30a, and the overall thickness of these portions is approximately uniform. There is.

is formed to approximately 1/J'2H. When formed in this way, if the original thickness is dl, the thickness d2 of the formed capsule will be approximately 0.37 times dl.
第２図は、上記カプセル３０内に太陽光収集装置４０を

図で、図中、４０は太陽光収集装置の受光面を示すが、
この受光面の直径りは次の理由によってＤ＝Ｊ２Ｒに選
ばれている。すなわち。FIG. 2 is a diagram for explaining an example of collecting sunlight by storing a sunlight collecting device 40 in the capsule 30, and in the figure, 40 indicates the light receiving surface of the sunlight collecting device. ,
The diameter of this light-receiving surface is selected to be D=J2R for the following reason. Namely.
今、太陽光収集装置の受光面４０が図示のように真上を
向き、太陽光りが真上の方向から来るものとすれば、中
心からの角度Ｏが４５＠の範囲内にある光はカプセル内

陽光を最も効果的に収集することができるが、このよう

にしておけば、水平方向から来る太陽光を効率よく太陽
光収集装置にて収集することができる。Now, if the light-receiving surface 40 of the sunlight collecting device faces directly above as shown in the figure, and the sunlight comes from directly above, the light whose angle O from the center is within the range of 45@ is the capsule. Light that enters the interior but is outside the 45° range enters Capsule 3.
It is reflected from the surface of the o and does not reach the inside of the capsule. Therefore, if the light receiving surface 40 of the solar light receiving device is set within this range, the area of the light receiving surface can be minimized and the sunlight introduced into the capsule can be collected most effectively. In order to do this, if the center P of the capsule head and the center of the light-receiving surface are made to coincide, then the diameter of the light-receiving surface should be selected to be D=J2R with respect to the radius R of the capsule head. Also, by doing this, the light receiving surface 40 of the sunlight collecting device is aligned with the two-dot chain line 4
When the vertical state shown at 0' is reached, the center P of the light receiving surface 40
The length from to the bottom end is D/2, but since D is D=7'2R as mentioned above, D/2=1/, /2R, and the length R1 of 1 cylindrical part 30b is Yoni 1/J2R
By doing so, the sunlight coming from the horizontal direction can be efficiently collected by the sunlight collecting device.

理解できよう。A disc-shaped transparent member is held airtight, heated and pressurized air is applied from one side 1, and negative pressure is applied to the upper side of the other side to melt and expand the disc-shaped member to form it. It is something. Therefore, in the present invention, the disc-shaped member is fixed so that the lower side and the ■ side are airtight, and the disc-shaped member is held horizontally, and heated pressurized air is applied from the upper I side. , the lower ■ side is molded under negative pressure, but at that time, by effectively utilizing the drop due to its own weight, it is possible to reduce the pressure applied to the upper side and the negative pressure applied to the lower side. can. In other words, when forming a hemispherical head, the pressure applied to the lower side and the negative pressure applied to the ■ side are effectively used to form a hemispherical head. When forming a hemispherical part by applying heated air and molding a cylindrical part, if the heated air is applied to the periphery of the cylindrical part as shown by the dotted arrow, the initial As the shaped head gradually descends, a straight cylindrical part can be formed by sequentially moving the position of the heated air upward accordingly. It is easy to understand that in the present invention, a Teflon coating may be provided on the capsule surface as described in the prior art.
