    摘要: This invention provides a high purity silica crucible having low impurity concentration in its inner portion, and its production method. The crucible, in which at least each content of Na and Li being contained in the depth of 1 mm from the inside surface is less than 0.05 ppm, is given by a production method of a high purity silica glass crucible, wherein a purity of the melted silica powder layer is increased by applying a voltage between a mold and an arc electrode to move impurity metals being contained in the melted silica glass layer to the outside, when the silica crucible is produced by arc plasma heating a raw material powder of silica in an inside surface of a hollow rotary mold. The method comprises, keeping an arc electrode potential of within ±500 V during an arc melting, applying a voltage of from −1000 V to −20000 V to a mold being insulated to the ground, and applying a high voltage to the un-melted silica powder layer of the outside.

    摘要: A packing-packaging machine includes: sheet feeding means; a horizontal bonding unit for forming a bag body by forming horizontal bonding on a tubular body at predetermined intervals; and an object dispensing unit for dispensing an object to be packaged to the bag body during a repetition of the formation of the horizontal bonding. The object dispensing unit includes a shutter for opening and closing a falling path of a predetermined amount of the object into the bag body. The shutter is opened and closed such that the predetermined amount of the object and another predetermined amount of the object fall with a spacing therebetween, and that before the horizontal bonding is formed on the bag body packed with the predetermined amount of the object which has been dropped during opening-closing operation of the shutter, the other predetermined amount of the object for a next bag body starts falling.

    摘要: A thread material cutting device is provided which is used in an extraction bag sheet manufacturing apparatus, the thread material cutting device having a compact apparatus configuration without the use of a cutter. An extraction bag manufacturing apparatus with the thread material cutting device incorporated therein includes welding means (first sealing device) in which tags retained on a carrying face of a carrier at prescribed intervals and a thread material arranged so as to be placed over the tags are press-heated and thereby welded on the carrier. The thread material cutting device has tension application means such as a pressing plate configured to engage with the thread material placed between adjacent tags so as to apply tension to the thread material. While the welding means is press-heating the thread material onto the tags, the tension application means applies tension to the thread material so as to cut the thread material.
