    摘要： A method of manufacturing high-quality preforms from glass melt, manufacturing glass elements, such as lenses, by press molding these preforms and, manufacturing optical elements by reheating and press molding these glass gobs. In the method glass gobs are continuously separated from a glass melt flow continuously flowing out of a nozzle and the separated glass gobs are formed with glass forming members that are intermittently or continuously moving. A support member is made to approach the front end of the nozzle, the front end of the glass melt flow is received by the support member, and the support member is dropped more rapidly than the rate of flow of the glass melt flow to separate a glass gob from the glass melt flow. The separated glass gob is transferred from the support member to a stopped or moving glass forming member to mold a glass article.

    摘要： An audio output device includes two digital microphone units that, upon receiving sound, convert the sound to PDM digital audio signals in which a state is represented by 1 or 0 in each predetermined period. The audio output device generates half-period digital audio signals, which are signals of a half period of the predetermined period, by using first digital audio signals and second digital audio signals that are the digital audio signals converted by the two digital microphones, where the states of the first digital audio signals are each reflected in one of two half periods corresponding to the predetermined period and states of the second audio signals are each reflected in the other half period. The audio output device then converts the half-period digital audio signals, which are generated by the generator, to analog audio signals and outputs the analog audio signals.

    摘要： A mat-shaped thermal insulator made of inorganic fiber, wherein at least a part of inorganic fibers is built-up in a direction parallel to lateral surfaces of the insulator, and said insulator is formed by cutting a fibrous built-up article formed by building-up inorganic fibers, to form cut built-up articles, rotating at least one of the cut articles by an angle of 90 degrees in a direction perpendicular to a longitudinal direction, to form a rotated built-up article in which the inorganic fibers are built-up in a direction parallel to lateral sides of the cut article, and integrating the cut articles and/or the rotated article transversally in a direction perpendicular to cutting direction. Preferably, the lateral surfaces of the insulator are inclined. Still preferably, longitudinal cuts are formed on the lateral surfaces of the insulator so as to make the insulator partially compressible.

    摘要： An Al2O3 film for covering a ferroelectric capacitor is formed by a sputtering process. The thickness of the Al2O3 film is preferably optimized according to amount of remanent polarization and fatigue tolerance required for the ferroelectric capacitor, for example, 10 nm to 100 nm. Next, oxygen is supplied to a PZT film via the Al203 film by executing a heat treatment in an oxygen atmosphere. As a result, an oxygen deficit in the PZT film is made up for. At this time, evaporation of Pb in the PZT film is suppressed because of the Al2O3 film, and deterioration of the fatigue tolerance responsive to decrease of Pb amount is suppressed. Subsequently, another Al2O3 film is formed as a second protective film by the sputtering process for opposing the deterioration factor in later process. The thickness of the Al2O3 film is preferably the thickness which sufficiently protects the ferroelectric capacitor from the deterioration factor in later wiring process.

    摘要翻译： 通过溅射法形成用于覆盖铁电电容器的Al 2 O 3 N 3膜。 Al 2 O 3膜的厚度优选根据强电介质电容器所需的剩余极化和耐疲劳性的量优化，例如10nm至100nm。 接着，通过在氧气氛中进行热处理，通过Al 2 O 3膜将氧气供给到PZT膜。 结果，PZT膜中的氧气缺乏。 此时，由于Al 2 O 3 O 3膜，PZT膜中的Pb的蒸发被抑制，并且抑制了响应于Pb量降低的疲劳强度的劣化 。 随后，通过溅射工艺形成另一个Al 2 O 3 3膜作为第二保护膜，用于与稍后的工艺中的劣化因子相反。 Al 2 O 3膜的厚度优选是在稍后的布线工艺中充分保护铁电电容器免受劣化因素的厚度。
