JP ‘465 discloses a process for making fine grained

water at a temperature greater than 350EC and a pressure
greater than 200 kg/cm (pages 1-2).2
The examiner relies upon the JP ‘465 example (pages 4-5)

produced have a size of 3F or less (answer, page 5). The
examiner argues that to obtain a product having a small
