Abstract: A evaluation process of a vibration level at the surface of silicon melt held in a silica glass crucible is provided by setting in the vacuum furnace, the test piece of the silica glass cut out from a silica glass crucible, melting a little amount of silicon put on said piece of the glass, and measuring a vibration cycle of the silicon melt. Moreover, a silica glass crucible not causing the vibration at the surface of the silicon melt held in the silica glass crucible is also provided, wherein the vibration cycle of a silica glass of a side wall of the crucible is controlled at more than ⅙ seconds.

Abstract: A reforming process of a quartz glass crucible in which the quartz glass crucible is reformed by an arc discharge generated by electrodes positioned around a rotational axis and configured to heat an inside surface of the crucible while the crucible is rotated. The process includes arranging electrodes in an electrode structure such that neighboring electrodes are positioned at regular intervals in a ring-like configuration; forming a stable ring-like arc between the neighboring electrodes, without generating a continuous arc between electrodes facing each other across a central portion of the ring-like configuration; heating the inside surface of the crucible; and removing a foreign substance located on the inside surface of the crucible or a bubble located under the inside surface of the crucible.

Abstract: [Object]: The present invention provides a process and a device for producing a quartz glass crucible, which generates a stable ring-like arc and is suitable for the production of an excellent crucible having the large open diameter.

Abstract: A modified synthetic silica powder is produced by heating in vacuum an amorphous synthetic silica powder produced by a sol-gel process, and then cooling the heated silica powder in an atmosphere containing helium. When the modified synthetic silica powder is fused and vitrified in a process of crucible production, the resulting quartz glass crucible contains hardly any bubbles.

Abstract: A composite crucible for pulling up monocrystalline silicone, which is superior in shape stability and suitable for a large-sized one is provided. The composite crucible is characterized in that a carbonaceous material as an outer layer and a quartz glass as an inner layer are integrally formed.

Abstract: A highly conductive region 18 serving as a surface of a drain layer 2 of a first conductivity type is diffused more deeply than a main diffused layer 36 and a diffused channel layer 37, and has a small conducting resistance. The highly conductive region 18 is surrounded by a diffused region 40 of a second conductivity type which comprises a diffused base layer 38 and a diffused guard ring layer 13. Therefore, the highly conductive region 18 does not form spherical junctions, and a depletion layer spreading in the highly conductive region 18 extends into the highly conductive region 18. The highly conductive region 18 thus has a high withstand voltage while maintaining the low conducting resistance.

Abstract: Disclosed are a method for detecting or quantitatively determining a single-stranded DNA fragment having a specific nucleic acid sequence through hybridization, and a reagent kit for the detection or determination. A carrier-bonded DNA probe comprising (a) a single-stranded DNA probe having a nucleic acid sequence complementary to the specific nucleic acid sequence of the single-stranded DNA fragment to be detected or quantitatively determined in a sample, and (b) a carrier comprising a substance with a very low adsorbance for DNA, as bonded together via or without a spacer therebetween, is hybridized with DNA fragments in the sample, and the hybridized DNA fragment is detected or quantitatively determined.

Abstract: The amount of residual carbon and hydroxyl groups in a synthetic quartz powder made by a wet process is reduced by baking the synthetic quartz powder in a low pressure atmosphere. Quartz glass crucibles made using the synthetic quartz powder have low bubble contents, and are particularly suited for growing single crystals.

Abstract: The invention relates to a single crystal pulling apparatus comprising; an outer crucible 11 positioned inside a chamber (gas tight container) 2, for storing a semiconductor melt 21, and an inner crucible 30 comprising a cylindrical partition body, mounted inside the outer crucible 11 to form a double crucible, and wherein a single crystal of semiconductor 26 is pulled from the semiconductor melt 21 stored inside the inner crucible 30. With this arrangement, the inner crucible 30 is made from quartz and comprises an inside layer A, an outside layer C, and an intermediate layer B which lies between the inside layer A and the outside layer C, and the intermediate layer B is made from quartz with a larger gas bubble content than the quartz which makes up the inside layer A and the outside layer C of the inner crucible 30.

Abstract: A carbonate spring bath system creates a bath water dissolved with CO.sub.2 gas and supplies the same to a bathtub. The system includes a source of a concentrated CO.sub.2 gas, a circulation path connected to the bathtub and including a booster pump for circulating a bath water from and into the bathtub. CO.sub.2 gas and air supply lines are connected to the circulation path upstream of the pump. The CO.sub.2 gas and air supply lines includes valves which are opened and closed to provide the CO.sub.2 gas and the air at a suitable mixture ratio such that the CO.sub.2 gas and air are forced to dissolve in the pressurized bath water. Disposed downstream of the pump is an accumulator for separating undissolved gas in the bath water and storing in a gas chamber the undissolved gas emanating from the bath water. A recycle line connects the gas chamber to the circulation path upstream of the pump to return the undissolved gas to the circulation path.
