A method of production of peeling layer paste used for producing a multilayer electronic device, having a step of preparing a primary slurry containing a ceramic powder having an average particle size of 0.1 pm or less, a binder, and a dispersion agent and having a nonvolatile concentration of 30 wt % or more, a step of adding to the primary slurry a binder-lacquer solution to dilute the primary slurry to prepare a secondary slurry having a nonvolatile concentration of 15 wt % or less and a content of the binder of 12 parts by weight or more with respect to 100 parts by weight of the ceramic powder, and a high pressure dispersion treatment step of running the secondary slurry through a wet jet mill to apply to the secondary slurry a shear rate of 1.5×106 to 1.3×107 (1/s).
摘要:
A camera system has a recording portion for recording an object image, a display portion for displaying an object image, a first blur correction portion for correcting blur of the object image displayed on the display portion by signal processing, and a second blur correction portion for optically correcting blur of the object image recorded by the recording portion. The camera system includes a controller for switching between a first blur correction mode in which the first blur correction portion is operated, a second blur correction mode in which the second blur correction portion is operated and a third blur correction mode in which both the first blur correction portion and the second blur correction portion are operated.
摘要:
A method for manufacturing a multi-layered ceramic electronic component includes positioning a multi-layered unit including a release layer, an electrode layer and a ceramic green sheet formed on a support sheet in such a manner that the surface of the multi-layered unit is located on a base substrate and a step of pressing the multi-layered unit toward the base substrate, thereby laminating the multi-layered unit on the base substrate, and employs as the base substrate a base substrate having such surface roughness as to include per 0.01 mm2 thereof not more than one protrusion that can penetrate the ceramic green sheet of the multi-layered unit laminated on the base substrate to half or more the thickness of the ceramic green sheet and include per 100 mm2 thereof not more than one protrusion that can completely penetrate the ceramic green sheet.
