    摘要： An improved process for the production of optical fiber porous preforms of predetermined refractive index distribution by the vapor-phase deposition method is disclosed wherein a glass material and a dopant material are subjected to flame oxidation by the use of an oxyhydrogen burner to form fine glass particles which are deposited on one end of a supporting rod adapted to move apart from the oxyhydrogen burner while rotating to allow a rod-like porous preform to grow thereon. The improved process is characterized in that the correlation between the shape of the deposition face and the refractive index distribution is previously determined mathematically, and on a basis of the correlation therebetween, a process variable such as the distance between the porous preform and the burner is adjusted to produce the desired shape of the deposition face whereby there can be obtained an optimum refractive index distribution.

    摘要： The invention is a method for producing a porous preform for use in the fabrication of an optical fiber at least two burners synthesize glass soot particles, one of which generates a double-layer flame and one of which is used for forming a core part of the preform. The method comprises the steps of supplying SiCl.sub.4 and optionally GeCl.sub.4 to the inner flame of the double-layer flame, and only SiCl.sub.4 to an outer flame of the double-layer flame to flame hydrolyze the supplied compounds and synthesize glass soot particles. Compounds SiCl.sub.4 and GeCl.sub.4 as glass-forming raw materials are supplied to the burner for forming the core part of the preform by depositing the generated glass soot particles on the lower end of a rotating starting member. The generated porous preform comprises a core part containing at least partly GeO.sub.2, and a surface having a low concentration of GeO.sub.2 which reduces cracking or peeling.

    摘要： An image processing apparatus has a line memory for writing and reading image data of one line. A write/read controller controls writing and reading the image data of one line in and from the line memory. A white line determiner determines whether an image corresponding to image data of one line being written in the line memory is a white line. An image processor performs specified image processing on the image data of one line read from the line memory by the write/read controller. An image processing controller generates an operation clock used in the image processor and causes the image processor to perform the specified image processing for the image data of one line determined not to be a white line and stops generating the operation clock and reads white data from a white data storage for the image data of one line determined to be a white line.

    摘要： A lubricating oil feeding structure that permits an adequate amount of lubricating oil to be fed to those parts around the transmission while avoiding an excess supply of lubricating oil to the lubricating oil passage in the shaft of the transmission. The transmission has a space (as a recess to hold the shaft therein) in which is arranged the oil guide part. The oil guide part has the bottomed cylinder, with its one end opened, the flange that flares outward at the open end of the bottomed cylinder, and the oil holes that communicate between the inside and the outside of the bottomed cylinder. The oil guide part is arranged in the space in such a way that the flange comes into contact with the outer race of the bearing.
