Abstract:
A lubricating system includes a port to provide access to a reservoir in a carriage base to allow lubricant to be injected into the reservoir and a number of channels molded into the carriage base to extract the lubricant from the reservoir and deliver the lubricant to locations where carriage bearings of the carriage base are in contact with a carriage rod of a printer to reduce friction.
Abstract:
A method for forming micron-sized or smaller drops of liquid, and the use of the method in fabricating micro electro mechanical and micro mechanical devices is disclosed. A micropipette is formed having an inside diameter no larger than the size of the drops to be formed. The micropipette is connected to a system capable of developing a positive and optionally negative pressure within the micropipette. The tip of the micropipette is placed in liquid. The liquid is drawn into the micropipette via capillary action or from the negative pressure developed by the system. The micropipette is then positioned to deliver liquid to an intended location on a surface. To deliver the liquid, a positive pressure is developed within the micropipette. The positive pressure forces a micron-sized or smaller drop of liquid out of the micropipette. The method can be used to form micron-sized or smaller drops of adhesive for fixing in place various structural members that form microdevices.
Abstract:
An improved release agent delivery apparatus is disclosed for use in laser printers, plain paper copiers, facsimile machines, and similar printing apparatus. The delivery apparatus comprises an absorbent textile core filled with release agent, a permeable membrane surrounding the textile core to form a sheathed wick member, and a mounting sleeve adapted to attach the sheathed wick member in operative contact with the printer. The apparatus has numerous operational advantages over existing oil delivery apparatus, including providing multiple contact surfaces for longer operational life before replacement, ease in cleaning and regeneration, improved durability and reduced wear, and more compact and versatile operation.
Abstract:
A surface of a substrate 11 (FIG. 2) is uniformly coated with a liquid L by wetting the surface with the liquid and compressibly contacting the wetted surface with an applicator member 10 having an outer layer 14 of a compressible liquid absorbing material with inverse sponge characteristics and an inner layer 13 of compliant material. Preferably the member is a roller 10 having a silicone rubber or polyurethane inner layer and a chamois outer layer. A plurality of the rollers 10 are arranged to be in compressive contact with the surfaces of a plurality of substrates 11 as the substrates are being removed from the liquid L (arrow A), the movement of the substrates 11 causing rotation (arrow F) of the rollers to apply a uniform coating of the liquid on the contacted surfaces.
Abstract:
Method of controlling the temperature of a tape element in a tape run utilizing a tape support element having a surface elongated in the direction of the tape run and for coaction with a surface of the tape element, the tape support surface having a tape-receiving part spaced from a tape delivery part, which method includes controlling the temperature of the tape support surface. The method includes the steps of intimately supporting the tape element by the support element, and introducing a relatively small quantity of a temperature-exchange liquid between the aforementioned elements in proximity to the tape receiving part to spread by capillarity in a thin film toward the tape delivery part. Such spreading of the thin liquid film is enhanced by moving the tape element toward the delivery part of the support.
Abstract:
Apparatus for applying offset-preventing liquid to a fuser roll structure incorporated in a xerographic reproducing apparatus. The apparatus for applying the liquid comprises an applicator roll for providing a film of liquid to a wick assembly having a fluorocarbon polymer fiber layer contacting the fuser roll structure and a capillary forming member cooperating with the applicator roll to convey liquid from a sump area to parts of the applicator roll remote from the sump.
Abstract:
A substrate processing apparatus includes a nozzle block in which a slit-like discharge port is formed and a controller. The controller controls an X-direction driver and a Z-direction driver, so that a nozzle block is moved on a substrate with a gap between the nozzle block and the substrate filled with a processing liquid. At this time, the processing liquid is applied onto the substrate. Thereafter, the nozzle block is separated from the substrate, so that a liquid column connecting the nozzle block to the substrate is formed. The nozzle block is moved such that the liquid column changes from a liquid contact state in which the liquid column is in contact with the processing liquid present in a discharge port to a non-contact state in which the liquid column is not in contact with the processing present in the discharge port.
Abstract:
A moistening system that significantly reduces the problems caused by contaminants in the moistening fluid is provided. The catch basin of a moistening system is provided with a filter that reduces the amount of contaminants contained in the recycled moistening fluid. Additionally, the moistening fluid is buffered with an acid that acts to dissolve the paper filler and other soluble debris that may be introduced into the moistening fluid, thereby significantly decreasing any blinding of components of the moistening system that would otherwise reduce the flow rate of the moistening fluid through the system. These ensure that sufficient moistening fluid is applied to the envelope flaps, which results in consistent and complete sealing of the envelope flaps.
Abstract:
An improved release agent applicator for use with a copying machine having a fixing device for pressure fusing a toner image to copy paper as the paper is passing between a fixing roll and a pressure roll. The fixing roll has in contact therewith a porous sheet or tube of poly(ethylene tetrafluoride) resin through which the release agent is applied to the fixing roll. The porous sheet or tube is installed on a support in such a manner that part of the sheet or tube projects from an opening of the support. The sheet or tube is provided with a backup which prevents the deformation of the sheet or tube. The backup is provided behind the sheet or tube and extends in the direction of rotation of the fixing roll.
Abstract:
An image forming apparatus comprises a rotatable photosensitive drum driving mechanism for rotating the photosensitive drum; and a cleaning blade which is capable of being in contact with the outer circumferential surface of the photosensitive drum and which removes a residual developer on the outer circumferential surface upon contact therewith.A recess is formed at part of the outer circumferential surface and holds lubricant therein; and the tip end of the cleaning blade feeds the lubricant in the recess to part of the outer circumferential surface of the photosensitive drum which is brought into contact with the cleaning blade to form a thin film of the lubricant upon contacting with the lubricant held in the recess as said photosensitive drum is rotated.
