Abstract:
Provided is a coating apparatus that suppresses the phenomenon in which a semisolid film is retained on the upper-end edge portion of the coating bath even after the circulation of the coating liquid is resumed, resulting in the occurrence of coating defects, and a method for producing an electrophotographic photosensitive member using the coating apparatus. The upper-end portion of the coating bath includes a first upper-end surface, a second upper-end surface that is positioned below the first upper-end surface and has an outer diameter larger than that of the first upper-end surface, and a step surface that interconnects the first upper-end surface and the second upper-end surface. The coating liquid is capable of overflowing from the coating bath, flowing along the second upper-end surface, and flowing while wetting the whole area of the step surface when the circulation is resumed.
Abstract:
Method for dip treatment of an optical element, wherein the optical element is held, while it is being dipped, by a holding ring, the ring including a hoop for draining and encircling a peripheral edge of the optical element, thereby exerting continuous linear contact with the peripheral edge, the hoop forming an arc over more than 180° and being provided at each of its two ends with an outwardly-directed drip tab pointing away from the optical element.
Abstract:
A system for coating fruit with a substance utilizing a vat that stores a coating substance which can be applied via a dipping process. A dipping cover having a rim is provided for engaging an upper rim of the vat. A dipping tray carries a plurality of fruit items and includes a plurality of receptacles for carrying the fruit items. The dipping tray has a profile smaller than the interior of the vat allowing the dipping tray to be lowered so that the coating substance contained within the interior of the vat may engage the fruit. The dipping cover is configured for supporting the dipping tray in an elevated position once the fruit has been coated allowing excess coating to be vibrated off the dipped fruit.
Abstract:
An electroless plating solution is accommodated in a plating tank of an electroless plating apparatus. A reference electrode and a counter electrode are immersed in the electroless plating solution. A conductive member is provided to be electrically in contact with a conductive portion of a long-sized substrate. The conductive member, the reference electrode, and the counter electrode are connected to a potentiostat. A main control device controls the potential of the conductive portion of the long-sized substrate by a potentiostat such that the potential of the conductive portion of the long-sized substrate with respect to a potential of the reference electrode is equal to a potential of the independent portion of the long-sized substrate with respect to the potential of the reference electrode.
Abstract:
An electroless plating solution is contained in a plating tank of an electroless plating apparatus. A reference electrode and a counter electrode are immersed in the electroless plating solution. A conductive member is provided to be electrically in contact with a conductive layer formed of a long-sized substrate. The conductive member, the reference electrode, and the counter electrode are connected to a potentiostat. The potentiostat controls an electric current that flows between the conductive layer formed of the long-sized substrate and the counter electrode such that a potential of the conductive layer formed of the long-sized substrate (working electrode) is at a constant level with respect to a potential of the reference electrode.
Abstract:
A powder dispensing system comprises an enclosure, a grate, a tub, an air filter and a fan. The enclosure has an upper opening and a lower opening. The grate extends across the upper opening. The tub holds powder and is supported by the grate. The air filter is supported within the enclosure beneath the grate. The fan is coupled to the housing and configured to force air from the enclosure through the lower opening.
Abstract:
An apparatus and method for coating products is disclosed herein. An exemplary apparatus comprises a vibration generating portion and a product coating portion. The product coating portion can include a coating application portion, a sifting portion, and an aligning portion. The exemplary apparatus can include a coating recycle portion as well. The vibration generation portion further comprises a motor vibration assembly secured to a frame wherein the frame is in communication with the product coating portion, such as a pan assembly, by springs that move the pan assembly with a vibratory motion. The product coating portion includes a series of angled steps that guide the coating and vibrating product upwards and forward, while simultaneously allowing the product to be agitated against the coating resting on the step surface. Additionally, the product coating portion can include a moveable wire belt conveyor assembly.
Abstract:
A method of curing a coated article in a curing oven, the method has the steps of delivering a plurality of coated articles on a travel path through an oven. One ore more excess coating sites are determined on the coated articles which are potential sources of excess coating which, if remaining following curing, will require remedial treatment before a subsequent painting step. A plurality of nozzles are provided in nozzle groups of one or more along the travel path in the oven. Each group of nozzles is trained on a specific excess coating site on the coated articles. A flow of air is delivering through each nozzle sufficient to remove the excess coating from the excess coating site. A sufficient number of nozzles are provided so that excess coating has been removed from the excess coating sites on the coated articles.
