摘要： An optical fiber comprising a core glass and a cladding glass therearound, wherein at least the core glass contains GeO.sub.2 as an additive to increase the refractive index with respect to the cladding glass. The fiber glass is prepared by heat treating a starting glass to separate out a B.sub.2 O.sub.3 --Na.sub.2 O-rich phase for subsequent acid leaching, and by sintering a residual glass with low concentrations of light absorbing impurities. Ingredients of the starting glass in weight percent are as follows: SiO.sub.2 :25 - 80 B.sub.2 o.sub.3 :10 - 30 Na.sub.2 O:3 - 12 GeO.sub.2 :3 - 40 A1.sub.2 o.sub.3 : 0 - 4

摘要： An optical exposure method in photolithography applied for precise processing when semiconductor devices are produced. A pattern on a photomask is projected and exposed on a register on a base plate with an exposure device including a deformation illumination system, a photomask and a projection lens. The deformation illumination system is composed of a light source, a diaphragm and a condenser lens, and the diaphragm is provided with a linear through-hole. The optical exposure method uses a ray of linear light for illumination or two rays of linear light for illumination that are parallel with the pattern. The two rays of linear light are symmetrical with respect to an optical axis. These rays are parallel with the pattern in a position separate from the optical axis of the exposure device when the photomask pattern is a line and space pattern.

摘要： A fine pattern having a high aspect ratio is precisely formed using a focused-ion beam system by depositing a pattern, detecting an image of the deposited pattern, comparing the image of the deposited pattern to data for a pattern to be formed, depositing again, if necessary, to form a portion of the deposited to be formed but omitted from the deposited pattern, and removing an excess portion of the deposited pattern or the further deposited portion.

摘要： A process for producing a transparent glass product having a refractive index gradient by the molecular stuffing method is described. A thallium compound is used as a dopant and, after a concentration gradient of the thallium dopant is formed, the porous glass product is heated up to the temperature region of 350.degree. to 550.degree. C. at a temperature-rising rate of 25.degree. to 150.degree. C./hour in a reducing gas atmosphere and then heat treated above 550.degree. C. in an inert gas atmosphere to collapse micropores in the porous glass product, thereby obtaining a glass product having a refractive index gradient which is transparent and free of light-scattering and coloration. The glass product is suitable as materials (preforms) for optical fibers or materials for rod-shaped lenses, particularly rod-shaped microlenses for microlens arrays and microlenses for coupling an optical fiber and a light source.

摘要： An electron beam exposure system for producing a desired pattern on a workpiece. The pattern is specified by predetermined pattern data. The pattern data is modified with correction data. The correction data is obtained from information indicating variations on the level of the surface of the workpiece due to an elastic deformation thereof during the exposure process. With the use of the correction data, the desired pattern is correctly reproduced as intended when the workpiece is fully supported and the surface thereof recovers its flatness.

摘要： A structure at a connection where at least two resin pipes are connected to each other end-to-end. The structure is characterized by annular resin body means provided on the inner periphery of the end of at least one of the resin pipes and having at least one end positioned in an annular recessed portion formed in the inner periphery of said one resin pipe. Since the above-mentioned end (which is more subject to the action of internal fluid than the other end) is positioned in the annular recessed portion, the resin body means is not eroded by the internal fluid.
