A method of manufacturing an extraction bag sheet including: (1) a step of placing and holding tags on a rotary supporting body at predetermined intervals; (2) threading a string into a continuous pattern on the circumferential surface of the rotary supporting body; (3) bonding the string to the tags; (4) supplying a water-permeable filter sheet onto the tags and the string; (5) bonding the water-permeable filter sheet to the string; and (6) bonding the water-permeable filter sheet to the tags. In the bonding steps of (3), (5), and (6), bonding heads are used which are moved reciprocally and oscillatingly about the center axis of the rotary supporting body and moved vertically relative to the circumferential surface of the rotary supporting body by an oscillation servo motor and a vertical movement servo motor.

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.

A manufacturing method for a plasma display member wherein generation of defects such as interruption and short-circuit of a pattern obtained after exposure and development is suppressed and yield is improved, even when a foreign material is adhered on a photomask or photomask is scratched. An exposing method for a display member wherein a display member having a photosensitive layer formed on a base substrate is exposed through a photomask having a desired pattern. The exposing method for the display member is characterized in that the photomask and the base substrate are relatively shifted during exposure operation.

A surface modified quartz glass crucible and a process for modifying the crucible includes a layer of a metal oxide on the whole or a part of the inside and/or outside of the crucible, and baking it. At least an inside surface of the crucible is coated with a said metal oxide of magnesium, calcium, strontium or barium. The coated layer of the crucible does not abrade easily and provides a high dislocation free ratio of silicon single crystals pulled by using the crucible.
