Abstract: This invention provides a cost-effective technique for mass-production of a cell culture vessel that allows mass cell culture to be performed in a manner that allows cells to be stably detached from the culture vessel. Specifically, the invention provides a method for producing a cell culture vessel suitable for large-capacity culture comprising cutting a long-sized cell support film to obtain a sheet-like cell support film, fixing the film to a first member, which is not closed, and bonding other members thereto. Thus, a cell culture vessel comprising a container section in which a cell support film is fixed to an inner wall surface can be produced.

Abstract: A recording apparatus has a nozzle (10a) containing a viscous substance (11) of a viscosity not lower than 300 cP. A recording electrode (12) is disposed on the nozzle (10a) at a position near the forward end of the nozzle (10a). A meniscus (13) of the viscous substance (11) is formed on the forward end of the nozzle (10a), and then an electric pulse signal corresponding to an image signal is applied to the recording electrode (12) to vibrate the meniscus (13) or to separate a small droplet of the viscous substance (11) from the meniscus (13) and to make the droplet fly. The droplet adheres to a recording medium (15) disposed opposite to the nozzle (10a) for recording. The timing of a droplet discharging operation for thus discharging droplets of the viscous substance (11) and the discharge amount of the viscous substance (11) can be controlled through the control of the pulse width or the amplitude of the voltage pulses of the electric pulse signal.
