  • Patent number: 8319808
    Abstract: According to one embodiment, there is provided an image forming apparatus, including an accommodation unit, an image forming unit, an image reading unit, an image erasing unit, a first medium processing unit, and a second medium processing unit. The first medium processing unit forms the image on the recording medium carried from the accommodation unit and discharges the recording medium on which the image is formed, based on the setting of a first image process mode. The second medium processing unit forms a test image on the recording medium carried from the accommodation unit, reads the test image, erases the test image, and returns the recording medium to the accommodation unit, based on a setting of a second image process mode.

  • Patent number: 7763223
    Abstract: In a synthetic method for porous silica crystals through a hydrothermal reaction, a method for synthesizing porous silica crystals with a size of 0.5 mm or larger in high reproducibility and efficiency is provided using a method for manufacturing the porous silica crystals, wherein a high concentration area with silicon is formed as a partial area inside a hydrothermal synthesis vessel, and at least a part of a surface-smoothed bulk material is present in the high concentration area with silicon to perform the hydrothermal reaction, the bulk material comprising a compound containing both silicon and oxygen as a supply source for a part or a whole of the structure composition elements of the porous silica crystals.
