摘要： A technique is disclosed herein for the enhancement of efficiency, and uniformity of light emission from a DC-operated fluorescent lamp. It involves the correlation of mercury vapor pressure within the lamp (which is dependent upon the temperature of liquid mercury within the lamp) with the magnitude and polarity orientation of the DC current applied to the lamp, and an optimization of these parameters along with lamp tube diameter.

摘要： A printbar assembly comprised of an array of light emitters, and array of gradient index lenses, and a light control film. The light control film, which is comprised of a plurality of microlouvers, is disposed such that it limits the angle at which light from the light emitters can enter the gradient index lenses. The light control film increases the depth of focus of the gradient index lens array without significantly reducing the effective radiometric efficiency.

摘要： An amalgam fluorescent lamp is designed to operate with minimum axial illumination variations when changing from an off to an on state. This is accomplished by incorporating at least three amalgam patches internal to the lamp. Two patches are located at opposite ends of the lamp, and at least a third patch is centrally located. Each patch has an associated thermistor ands external heater sleeve. The patch temperature which correlates wiht the optimum lamp operating temperature is continuously monitored and adjustments are made to the heater sleeve elements to maintain the patches at desired optimum temperature.

摘要： Flash lamp intensity control in which a small preflash lamp first exposes each document on the platen of an electrostatographic machine, a photosensor generates a signal representative of the intensity of the light reflected from the platen, and a controller increases power to the main flash exposure lamps in response to the signal where the measured intensity is less than the normal exposure intensity of the main flash lamps.

摘要： In a full-frame flash electrophotographic printing machine, an imaging system is provided which incorporates a flash lamp directly coupled to an ac line input to enable document exposure. The imaging system also includes a lens whose movement is synchronized with a moving photoreceptor so that an exposure occurs registered at the same image area of the photoreceptor. The invention further includes circuit means for detecting zero crossing points of the line voltage and for generating signals which are used to trigger the lamp into operation at some point during an 8 msec, half cycle of line operation. Further circuit means are provided for controlling exposure levels to conform to detected density of the document being copied. In a second embodiment, the control circuitry is used to couple the ac line into a flash fuser assembly to fuse a transferred image on an output record medium.

摘要： A low pressure sodium vapor lamp including a sodium vapor discharge tube and a light reflector partially surrounding the discharge tube and defining a light transmission aperture for desired directional light output. The light reflector is in tangential contact with the discharge tube on the surface thereof opposite to the light aperture. The contact between discharge tube and light reflector provides a thermal coupling for heat conduction from the discharge tube. The area of this thermal coupling thus becomes the coolest portion of the discharge tube, the "cold spot" of the lamp where excess sodium is condensed.

摘要： A technique for charging a dielectric surface by corona discharge is described in which the voltage applied to a stationary corona wire is steadily increased over an initial time period to cause the gradual increase in voltage level on the dielectric surface over the same time period. The voltage on the stationary dielectric surface increases with the wire voltage. The potential difference between wire and plate is kept below the sparking voltage, but above the corona current threshold voltage.After the initial phase, the dielectric surface is moved relative to the corona wire (e.g. a rotating xerographic drum). The corona wire can now be held at its high voltage without sparking between the wire and the dielectric surface.

摘要： An imaging module mounting structure is used for mounting an imaging module to an imaging device that has a support member and a rotatable photoreceptor. The imaging module includes an imaging bar and a corona generating device. The imaging module mounting structure includes a pair of pivot block devices which are pivotably connected to the support member in a spaced apart relationship. The imaging bar and the corona generating device are secured to each one of the pair of pivot block devices. Each pivot block device includes a cam follower element. The pair of pivot block devices are operative to flex independently of one another while the photoreceptor rotates so that the respective cam follower elements remain in contact with the rotating photoreceptor to compensate for photoreceptor run out. A method for practicing the present invention is also described.

摘要： Uniformity light output of an LED printbar is achieved by a technique which senses the operational on time of each LED. When the on time difference between the LED with the longest on time and the LED with the shortest on time exceeds a predetermined value, the outputs of at least some LEDs comprising the printbar are compensated for to normalize their light output. This normalization is achieved via a drive circuit which drives each LED based upon correction data, and by determining an update of the correction data based upon the difference between the on time of individual LEDs. The correction data is determined when the difference between the on time of the LED with the longest on time and the on time of the LED with the shortest on time exceeds a predetermined maximum difference.

摘要： Lamp operating voltage levels are reduced by using a boost circuit to initiate a triggering sequence in one of two lamps connected in series. The boost circuit is connected across one of the lamps at a connector point common to the two lamps. In a preferred embodiment, trigger pulses are applied sequentially to each lamp, the boost circuit voltage contained in an associated capacitor is discharged through the first triggered lamp, causing it to begin conduction. Most of the voltage from a main storage capacitor then becomes available to break down the second lamp.
