Abstract: A sorting device includes a transport unit, an identification unit, and a plurality of nozzles. Each of the plurality of nozzles has a valve that adjusts a flow amount of pulse air, a pulse air flow path that is connected to the valve, and a pulse air blowing port that is arranged at a tip end of the pulse air flow path. The pulse air flow path has at least one bent portion. An adjustment flow path is connected to the bent portion of the pulse air flow path. An adjustment member capable of increasing and decreasing a volume of the adjustment flow path is provided in the adjustment flow path.

Abstract: An endoscope which promotes downsizing and cost reduction, and a manufacturing method of an endoscope are provided. For this reason, in an endoscope, a lens unit containing a lens in a lens tube, an image capturing element of which an image capturing surface is covered with element cover glass, and an adhesive resin fixing the lens unit of which an optical axis of the lens is coincident with the center of the image capturing surface to the element cover glass with a separation portion are disposed.

Abstract: Provided is a substrate processing method that prevents generation of watermarks on a substrate and can be performed at a low cost. The method controls the ambient humidity around the substrate depending on the kind of the chemical liquid, when the substrate is processed with the chemical liquid. The control of the humidity is performed at least in a drying step that dries the substrate W. In one embodiment, the ambient humidity around the substrate is controlled when a fluid containing IPA as a drying fluid is supplied to the substrate W after processing the substrate W with the chemical liquid.

Abstract: A liquid processing apparatus is arranged to planarize a film on a substrate by supplying onto the film a process liquid for dissolving the film while rotating the substrate. The apparatus includes a substrate holding member configured to rotatably hold the substrate in a horizontal state, a rotation mechanism configured to rotate the substrate holding member, and a liquid supply mechanism configured to supply the process liquid onto a surface of the substrate. The liquid supply mechanism includes first and second liquid delivery nozzles configured to deliver the same process liquid. The first liquid delivery nozzle has a smaller diameter and provides a smaller delivery flow rate, as compared to the second liquid delivery nozzle. The first liquid delivery nozzle is inclined to deliver the process liquid in a rotational direction of the substrate, and is movable between a center of the substrate and a peripheral edge thereof.

Abstract: An object of the present is to uniform particle diameters and speeds of liquid droplets in a two-fluid nozzle for cleaning substrates which mixes gas and liquid internally and injects liquid droplets with gas so as to clean a substrate. The two-fluid nozzle for cleaning substrates has a gas supply passage for supplying gas, a liquid supply passage for supplying liquid, and a lead-out passage for leading out internally-formed liquid droplets, wherein an injection port for injecting liquid droplets to the outside is formed at the front end of the lead-out passage, and wherein a cross-sectional area Sb of the injection port is formed smaller than a cross-sectional area Sa of the lead-out passage, and a cross sectional area Sc of an exit of the gas supply passage is formed smaller than the cross-sectional area Sa of the lead-out passage.

Abstract: The present invention provides a substrate cleaning method which is intended to securely remove matters attached to the periphery of a substrate to be processed and enhance the yield of products as well as intended to lengthen the life of the apparatus. This substrate cleaning method comprises the steps of: cleaning the periphery of a substrate by contacting a periphery cleaning member 10 with the periphery of the substrate W; and removing matters from the periphery cleaning member, the matters once attached to the substrate and then transferred therefrom and attached to the periphery cleaning member. The step of cleaning the periphery using the periphery cleaning member and the step of removing the attached matters from the periphery cleaning member are performed at the same time.
