    摘要: On an apparatus for developing latent images of diazotype prints with a developer liquid containing an organic amine or amines as the developing agent, the tendency of the diazotype paper to curl and wind round the applicator roller is effectively precluded by the addition of a very small amount of a fluorocarbon non-ionic surface active agent. The amount of the agent is preferably in the range from 0.01 to 1% of the total weight of the developer composition.

There is also disclosed a method for manufacturing a silicon single crystal in accordance with the Czochralski method, wherein during the growth of a silicon single crystal, a furnace temperature is controlled such that a temperature gradient difference &Dgr;G (=Ge−Gc) is not greater than 5° C./cm, where Ge is a temperature gradient (° C./cm) at a peripheral portion of the crystal, and Gc is a temperature gradient (° C./cm) at a central portion of the crystal, both in an in-crystal descending temperature zone between 1420° C. and 1350° C. or between a melting point of silicon and 1400° C. in the vicinity of the solid-liquid interface of the crystal. The method maintains high productivity and enables a silicon single crystal and silicon wafers to be manufactured such that a defect density is very low over the entire crystal cross section, and the oxygen concentration distribution over the surface of each silicon wafer is improved.
