In an example, a method including dispensing a liquid onto a first portion of a surface of a substrate and dispensing a solution comprising colloidal spheres onto a second portion of the surface of the substrate. The method additionally includes agitating the colloidal spheres to disperse the colloidal spheres along the first portion and the second portion of the surface of the substrate and directing air flow above the colloidal spheres inducing rotation of the colloidal spheres. In another example, a method includes positioning a retaining ring on a surface of a liquid above a substrate below the surface of the liquid and dispensing a solution comprising colloidal spheres onto the surface of the liquid within a surface area of the retaining ring. The method further includes agitating the surface of the liquid and the colloidal spheres to disperse the colloidal spheres along the surface area of the retaining ring.

A first edible layer is placed atop a tray and inside a first annular member, leaving an annular gap around the edible layer. A spreadable material is spread atop and laterally on the first edible layer. A second annular member is stacked upon the first annular member with a second edible layer centered in the second member but with an annular gap between the two. Spreadable material atop and laterally to the second edible layer. The annular members each have an overall transverse dimension greater than its height. These members are part of a reusable kit with the first member has an outwardly projecting pair of handles A tool for shaping spreadable material is shown as a plate with an opposite pair of finishing edges, one being straight, the other undulating. The lower edge of the tool is located between the finishing edges, and has an opposite pair of guide notches. Each of the notches can be pressed against the edge of the tray to regulate the tool's working depth.

In solder printer, solder supply device uses positive and negative pressure supply device to apply pressure inside air chamber to move solder cup inside outer tube, such that solder paste is supplied from supply nozzle. Controller, when supply of solder paste from supply nozzle is stopped, performs drive control of positive and negative pressure supply device to decrease the pressure inside air chamber, and uses timer to measure the time required from the starting of decreasing the pressure inside the air chamber to when the pressure inside air chamber has reached a set pressure. Because this required time corresponds to the movement amount of solder cup from the start of supply of the solder paste to when supply is stopped, controller using the measured required to estimate the remaining amount of the solder paste in detail with good accuracy.

An electrode active material coating device includes a transfer unit for continuously transferring a substrate in a first direction; a coating die for forming a coated portion by ejecting an electrode active material slurry on the substrate; and a guide unit including a guide portion that moves along the first direction between the coating die and the substrate.

The present invention relates to an apparatus for conducting assays on samples and/or processing of samples. The apparatus comprises a rotatably arranged cylindrical sample holder for holding a sample at a lateral surface of the cylindrical sample holder. The cylindrical sample holder is configured to be at least partly covered by a liquid layer. The apparatus further comprises a liquid dispensing means configured to add liquid to the liquid layer, a reagent dispensing means configured to add a reagent to the liquid layer and a liquid contacting means configured to distribute liquid within said liquid layer. The liquid contacting means comprises a plate-like element flexibly assembled in relation to the cylindrical sample holder. The present invention also relates to a method for conducting assays on samples and/or processing of samples.

An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates on demand for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.

A raw material solution (6), in which an organic semiconductor material is dissolved in a solvent, is supplied to a substrate (1). The solvent is evaporated so that crystals of the organic semiconductor material are precipitated. Thus, an organic semiconductor thin film (7) is formed on the substrate (1). An edge forming member (2) having a contact face (2a) on one side is used and located opposite the substrate (1) so that the plane of the contact face (2a) intersects the surface of the substrate (1) at a predetermined angle. The raw material solution (6) is supplied to the substrate (1) and formed into a droplet (6a) that comes into contact with the contact face (2a). The substrate (1) and the edge forming member (2) are moved relative to each other in a direction parallel to the surface of the substrate (1) so as to separate the edge forming member (2) from the droplet (6a), and while the raw material solution (6) is supplied so that a change in size of the droplet (6a) with the relative movement is maintained within a predetermined range, the solvent contained in the droplet (6a) is evaporated to form the organic semiconductor thin film (7) on the substrate (1) after the contact face (2a) has been moved. In this manner, a large-area organic semiconductor single crystal thin film having high charge mobility can be manufactured by a simple process using a solvent evaporation method based on droplet formation.
