    摘要： In order to reduce concentrations of impurities in an inner layer of a quartz crucible for pulling a silicon single crystal which comprises an outer layer made of quartz glass and an inner layer formed on the inner surface of the outer layer, a migration-preventing layer is formed between the outer and inner layers, wherein the migration-preventing layer prevents migration of the impurities such as alkaline metals included in the natural quartz glass in the outer layer to the synthetic quartz glass in the inner layer. The method of producing a crucible using a mold with an upper opening comprises the steps of: feeding a first quartz powder into the mold along an inner surface of the mold to pile up the first quartz powder in a layered structure and form a preform of the first quartz powder; melting a part of the preform by heat radiated from inside the preform; cooling the preform to solidify and form a crucible substrate of an opaque quartz glass layer; generating a high temperature gas atmosphere inside the substrate during or after formation of the substrate; feeding a second quartz powder containing aluminum or in combination with an aluminum-containing component into the gas atmosphere and melting it in the gas atmosphere; settling the second quartz powder melt flying from the gas atmosphere on an inner surface of the substrate to form an aluminum-containing intermediate quartz glass layer; feeding a third quartz powder into the gas atmosphere and melting it in the gas atmosphere; and it as settling the third quartz powder melt flying from the gas atmosphere on the inner surface of the aluminum-containing quartz glass layer to form a transparent quartz glass layer with high purity.

    摘要： An analytical method for the quantitative determination of the impurities in silicon dioxide by which trace amounts of hardly soluble impurities contained in silicon dioxide can be reliably decomposed and converted into a solution so that the contents of all of the impurities contained in silicon dioxide or, in particular, zirconium in a natural quartz powder can be accurately determined. Silicon dioxide is decomposed with hydrofluoric acid or an acid mixture of hydrofluoric acid and another inorganic acid to give a decomposition solution which is, as such or after admixture with another inorganic acid, subjected to evaporation to dryness and the residue is heated to cause fusion with addition of a salt or hydroxide of an alkali metal followed by dissolution of the salt or hydroxide of an alkali metal with pure water or with an aqueous solution of an inorganic acid to give an aqueous solution which is subjected to quantitative analysis of the impurities therein.

    摘要： In a switching network through which a path between a source terminal and each of destination terminals is formed, a set of destination addresses is generated at the source terminal, and each of the destination addresses is transmitted from the source terminal to a destination switch node accommodating the destination terminal. Each switch node on the path receives a first set of destination addresses from a previous switch node or the source terminal, and decides whether each destination address of the first set is accommodated in the switch node. Based on the decision, the switch node divides the first set into a plurality of second sets each corresponding to one route of the switch node. Each second set is transmitted to the next switch node through a corresponding route. The next switch node performs the same steps as the switch node mentioned above.

    摘要： To accurately reproduce multimedia information even if a pen type reading device for manually reading the multimedia information recorded to be capable of being optically read is not scanned perpendicularly to a sheet but is scanned at an inclination angle with respect thereto, a CCD arranged in the pen type reading device picks up a dot code from the sheet having a portion in which the multimedia information is recorded as a dot code capable of being optically read. A field memory stores the picked dot code as image data. A demodulating circuit demodulates the image data stored in the field memory. A subsequent signal processing circuit performs predetermined processing of the demodulated image data and outputs the resultant data as the original multimedia information. In this case, an inclination sensor arranged at the rear end of the pen type reading device detects an inclined state of the pen type reading device with respect to the sheet. A CPU, a coordinate conversion circuit, and an address/coefficient generation circuit determine a read address of the image data from the field memory in accordance with the inclined state of the pen type reading device with respect to the detected sheet.
