Japanese Unexamined Patent Application Publication No. 2099-99999, forexample, proposes forming a coating of platinum or platinum alloy on the entire surface
of a body (fusion cell) made of a refractory such as fireproof bricks or the likeby flame spraying, to solve the problem of lower quality due to erosion of therefractory.
[0008]
Now, a lower tip 103 of the body 100 made of fireproof bricks is somewhat
rounded, as shown in the enlarged illustration in Fig. 1. The reason is that if thelower tip 103 is sharp, it is easily chipped during manufacturing of the body 100
or while forming plate glass g. This can lead to serious trouble, such as a fissure
starting in the body 100 starting at the chipped portion.
[0009]On the other hand, the rounded lower tip 103 of the body 100 can lead to asituation where molten glass gm separates from side faces 102 of the body 100 before
fusing at the lower tip 103. Once this happens, a gap X such as illustrated in Fig.
1 will be formed between the lower tip 103 of the body 100 and the molten plate glassg.
[0010]
Formation of such a gap X results in air in the gap X finding its way into
the fused portion when fusing the molten glass gm, creating air bubbles in the plate
glass g, which is a deteriorating factor of the product quality of the plate glassg.
[0011]
Coating the surface of the refractory body 100 with platinum or the like byspraying, as in Japanese Unexamined Patent Application Publication No. 2099-99999,
does nothing to change this situation. That is, even if the surface of the body 100is coated, the coating invariably is rounded, conforming to the shape of the lower
tip 103 of the body 100. Accordingly, the gap X illustrated in Fig. 1 may still beformed even if a body 100 coated by platinum or platinum alloy by thermal spraying
is used, so the problem of defects such as bubbles still may occur.

[0012]The present invention has been made in light of the above-described situation,
and accordingly it is an object of the present invention to prevent defects such as
bubbles from being formed in plate glass.

A knitted glove according to the present invention was knitted using fivestrands of the composite yarn 5 produced in the first embodiment, by a 7-gauge glove
knitting machine manufactured by Shima Seiki Mfg., Ltd. The cutting resistance ofthe knitted glove according to the present invention was 16,256 cycles. Five strandsof 100% Twaron spun yarn 20/2 were similarly used to knit a reference knotted glove
by the 7-gauge glove knitting machine manufactured by Shima Seiki Mfg., Ltd. The
cutting resistance of the reference knitted glove was 16 cycles. The hard textureof the knitted glove according to the present invention made it less comfortable towear than the reference knitted glove, but this presented no problem with regard tousability. The knitted glove according to the present invention was also produced
at a lower cost than the reference knitted glove.

A tensioner (10) for belt transmission system, comprising:a cylinder (11) with a first bore (13) and an oil path (18) inside the cylinder (11), theoil path (18) communicating with the first bore (13);a piston (12) with a second bore (17) inside the piston (12), the piston (12) being
inserted into the first bore (13);a coil spring (16) slidably stored inside the second bore (17), the coil spring (16)having respective ends in contact with a bottom portion of the second bore (17) and incontact with a bottom portion of the first bore (13); anda check valve (19) that allows a flow of hydraulic oil from the oil path (18) to the firstbore (13) and restricts a reverse flow of the hydraulic oil flow, wherein
the piston (12) has an outer peripheral in a part of which a piston side rack (20) isformed,
the cylinder (11) includes:
an aperture (22) that communicates with the first bore (13);a cylinder side rack (21) that fits the piston side rack (20) through theaperture (22); anda biasing portion (25) that biases the cylinder side rack (21) in a direction

to the piston side rack (20).
