摘要:
An X-ray exposure apparatus includes a stage for holding a mask having a pattern for circuit manufacturing, a stage for holding a wafer to be exposed to the pattern of the mask with X-rays, and a reflection reduction imaging system, disposed between the mask stage and the wafer stage, including a reflecting mirror arrangement, containing at least three, but not more than five, reflecting mirrors coated with multi-layer films for receiving X-rays from the mask and directing them to the wafer to expose the wafer to the pattern of the mask with the X-ray in a reduced scale.
摘要:
An anticariogenic or antiperiodontitic agent containing, as an active component, adenosine or its derivatives having an antibacterial activity against Streptococcus mutans or Bacteroides gingivalis. This anticariogenic or antiperiodontitic agent has strong inhibitory effects on the growth of Streptococcus mutans causing dental caries and Bacteroides gingivalis causing periodontitis and has neither influence on intestinal microflora nor any side-effects when orally administered.

A bacterial cell product having hypocholesterolemic and/or hypotriglyceridemic activity in mammals obtained by cultivating a microorganism belonging to the genus Streptococcus and having a N-acetyl-.beta.-D-glucosaminidase activity in an adequate culture medium therefor, and collecting the cultivated microorganism from the resultant culture.
摘要:
In order to provide a method for effectively separating red mud generated during alumina-extraction treatment of an alumina ore containing goethite as an iron component, the alumina ore containing goethite as an iron component is treated with an alkaline solution at 110-160° C., to thereby take up alumina components through extraction, and a settling aid formed of a water-soluble polymer including, as an effective component, a copolymer containing, as a monomer component, a vinylhydroxamic acid compound or a salt thereof (A) and having an average molecular weight of at least 2,000 is added to the resultant extract, to thereby settle the red mud for separation thereof.

This hypocholesterolemically active protein is derived from a microorganism belonging to the genus Streptococcus.
摘要:
An X-ray exposure apparatus wherein a member sensitive to X-ray is exposed to a pattern formed on a mask with the X-rays, includes an X-ray source for emitting X-rays, an irradiation chamber for accommodating the mask and the sensitive member and exposing them to the X-rays emitted by the X-ray source within the chamber and a vacuum pump for evacuating the chamber to effect the exposure operation in a vacuum.
摘要:
Aluminum hydroxide having a particle size of 2 to 30 .mu.m and having small specific surface area and low resin filling viscosity can be prepared by using precipitated aluminum hydroxide composed of secondary agglomerated particles having a primary particle size almost equal to the desired average particle size of intended pulverized aluminum hydroxide as the starting material to be pulverized and pulverizing this starting aluminum hydroxide. This aluminum hydroxide has an average particle size of 2 to 30 .mu.m, a surface roughness coefficient Sr/Sc (in which Sr represents the specific surface area of particles measured by the nitrogen adsorption method and Sc represents the specific surface area calculated from the size of particles approximated to spheres while taking the particle size distribution of particles into consideration) smaller than 2.5 and a linseed oil absorption smaller than 30 cc/100 g as determined according to JIS K-5101.
