  • Publication number: 20240092078
    Abstract: First, a correction area, which is a part of area where a second ink (typically, white ink) is to be ejected among the area on base material, is determined. Next, density data is corrected so that the second ink is ejected onto the correction area. Thereafter, actual printing on the base material is started. Then, the second ink is ejected onto the correction area, and a first ink (typically, color ink) is ejected onto the second ink that has been ejected onto the base material in the correction area.

  • Patent number: 11915951
    Abstract: A plasma processing apparatus includes a stage disposed in a processing chamber for mounting a wafer, a plasma generation chamber disposed above the processing chamber for plasma generation using process gas, a plate member having multiple introduction holes, made of a dielectric material, disposed above the stage and between the processing chamber and the plasma generation chamber, and a lamp disposed around the plate member for heating the wafer. The plasma processing apparatus further includes an external IR light source, an emission fiber arranged in the stage, that outputs IR light from the external IR light source toward a wafer bottom, and a light collection fiber for collecting IR light from the wafer. Data obtained using only IR light from the lamp is subtracted from data obtained also using IR light from the external IR light source during heating of the wafer. Thus, a wafer temperature is determined.

  • Patent number: 10876106
    Abstract: In order to interpret an arbitrary sequence region in many genes in many cells, it is necessary to degrade a nucleic acid into fragments and introduce a sequence that is different from one cell to another into each of the fragments. However, in the conventional configuration for analyzing many cells, there has been a problem that mixing of the degraded fragments among areas occurs before a tag sequence unique for each of the areas is introduced. The present invention provides a system for capturing a nucleic acid extracted from a cell in each of plural areas on a substrate and synthesizing a complementary DNA (cDNA) of the nucleic acid for each of the areas, wherein the system also includes a means for immediately introducing a tag sequence unique for each of the areas to the reaction product.
