A substrate treating apparatus includes a plurality of solution treating units for performing solution treatment of substrates, and a plurality of individual gas supply devices provided to correspond individually to the solution treating units, each for supplying gas at a variable rate only to one of the solution treating units. The solution treating units perform the solution treatment by supplying treating solutions to the substrates. The individual gas supply devices supply gas only to the solution treating units corresponding thereto. The individual gas supply devices supply the gas at adjustable rates to the solution treating units. The rate of gas supply to the solution treating units can therefore be varied for each solution treating unit.

A substrate treating apparatus includes a treating section for treating substrates. The treating section has a front face and a rear face both connectable to an indexer section for feeding the substrates to the treating section. Such substrate treating apparatus can improve the degree of freedom for arranging the treating section and the indexer section.


A susceptor of a holding part for holding a semiconductor wafer includes a disc-shaped holding plate, an annular shaped guide ring, and a plurality of support pins. The guide ring has an inside diameter greater than the diameter of the semiconductor wafer and is installed on the peripheral portion of the top face of the holding plate. The guide ring has a tapered surface along the inner circumference. The semiconductor wafer before irradiated with flash light is supported by the support pins. The annular shape of the guide ring increases the contact area when the semiconductor wafer that has jumped off the susceptor and fallen when irradiated with flash light collides with the guide ring, thus reducing the impact of the collision and preventing cracks in the substrate.

An evaluation method of a spheroid comprises specifying a spheroid region taken up by the spheroid out of the image including the spheroid and a surrounding region thereof (S105), obtaining an average value of an optical density of the spheroid and a magnitude of a variation of the optical density in the spheroid from an image density of the spheroid region (S106), obtaining a circularity of the spheroid from a contour of the spheroid region (S107), obtaining a sharpness of the spheroid from the image densities of the spheroid and the surrounding region thereof (S108), and obtaining the collapse degree of the spheroid by substituting the average value of the optical density, the magnitude of the variation of the optical density, the circularity and the sharpness into a predetermined operational expression (S109).

An imaging apparatus comprises: a culture container including an accommodation space for accommodating a sample carrier carrying biological samples in a culture environment for the biological samples and a first transparent part making the accommodation space observable from outside; and an imager that images the biological samples in the accommodation space via the first transparent part.


A technique which makes it possible to more precisely evaluate how a chemical substance is efficacious upon a cell aggregate is suggested. An efficacy evaluation method for evaluating a drug efficacy of a chemical substance upon a cell aggregate inside a liquid which is contained in a container comprises: acquiring tomographic images of the cell aggregate which are imaged along cross sections which approximately match with a vertical plane (Step S102); calculating a feature amount of the cell aggregate based on the tomographic images (Step S105); and determining the drug efficacy of the chemical substance based on the calculation result of the feature amount.

This liquid ejecting apparatus includes an ejecting head (20), a liquid reservoir, a pressurizing part for the liquid reservoir, a supply passage, and an outlet passage. The ejecting head (20) includes a liquid flow passage (22), liquid filling chambers (23, 24) in communication with the liquid flow passage (22), and a plurality of nozzles (44) provided for the respective liquid filling chambers (24). When the pressurizing part performs pressurization, with the communication through the outlet passage ensured, a liquid in the liquid reservoir flows through the supply passage and is supplied through a supply port (221) to the liquid flow passage (22). Part of the liquid supplied to the liquid flow passage (22) is drained through an outlet port (222). This produces flows of liquid different from those produced during the ejection of the liquid from the nozzles (44) and directed from the supply port (221) toward the outlet port (222). Thus, precipitable ingredients accumulated in the liquid flow passage (22) are efficiently dispersed. That is, the accumulation of the precipitable ingredients in the ejecting head (20) is efficiently eliminated in the liquid ejecting apparatus capable of controlling the ejection of the liquid from the nozzles (44).


A method for limiting the amount of ink discharged in a photocurable inkjet printing apparatus includes a conversion step of converting, an input grayscale value to the amount of ink; and a limit value setting step of setting, a limit value of the amount of ink discharged, for each of a secondary color not including a K color component, a tertiary color not including a K color component, and a color including a K color component. In the limit value setting step, the limit value for the tertiary color not including a K color component is set to a smaller value than the limit value for the secondary color not including a K color component, and the limit value for the color including a K color component is set to a smaller value than the limit value for the secondary color not including a K color component.

An inkjet printing apparatus includes a transport speed detector for detecting transport speed of a printing medium, an inkjet head having a plurality of discharge portions for discharging ink droplets from the discharge portions for printing, and a flushing controller for carrying out discrete flushing from the discharge portions. For an acceleration area of the printing medium where the transport speed detector detects an increase in transport speed before printing, a first discharge rate is set as discharge rate of the ink droplets per unit time for the discharge flushing. For a constant speed area of the printing medium where the transport speed detector detects a substantially constant transport speed during printing, a second discharge rate lower than the first discharge rate is set as discharge rate of the ink droplets per unit time for the discharge flushing.


A meandering correction apparatus includes a transport mechanism (10), an orientation measurement part (20), a Youngs modulus calculation part (63), a meandering prediction part (64) and a meandering correction part (40). The transport mechanism (10) transports an elongated strip-shaped base material (9) in a longitudinal direction thereof along a transport path. The orientation measurement part (20) measures fiber orientations of the base material (9) in respective measurement regions on the transport path, the measurement regions being different in widthwise position from each other. The Youngs modulus calculation part (63) calculates Youngs moduli of the base material for the respective measurement regions, based on the fiber orientations. The meandering prediction part (64) predicts subsequent meandering of the base material, based on the Youngs moduli, to output meandering prediction information. The meandering correction part (40) corrects the widthwise position of the base material, based on the meandering prediction information. The meandering correction is made based on the fiber orientations of the base material. Thus, the widthwise position of the base material is corrected without depending on only edge sensors.
