Abstract: Dots for producing a multiple tone electrostatic latent image are formed by selectively discharging a charged surface with a scanned laser beam. The multiple tones are produced by pulse width modulation of the laser beam according to the tones required in the dots. High resolution is maintained by limiting the diameter of toner particles to 1/5 to 5 times the minimum exposed dot dimension. A laser beam exposure device includes a galvanometer mirror from which the scanning laser beam is reflected. The galvanometer mirror is tilted in synchronism with the conveying direction of the surface being scanned in order to maintain focus of the laser beam on the surface. In one embodiment, the modulation of the laser beam is produced by a combination of a digital counter and a delay circuit. The counter counts clock pulses until a first specified value is reached. A counter output pulse is generated during this counting. The delay circuit extends the counter output pulse to yield the final output pulse width. A developing system applies a positive voltage to a surface of a first conductor over which an object containing the electrostatic latent image is moved. A toner suspension is applied to the surface during this time. The object on which the image is being developed and a second conductor, adjacent a second surface of the first conductor, are given ground potential.

Abstract: Es wird ein Hydraulikkreis für ein Fahrzeug beschrieben, der eine durch die Antriebsmaschine (10) des Fahrzeuges angetriebene Haupthydraulikpumpe (12) aufweist, die der Druckversorgung wenigstens eines hydraulischen Abnehmers (20, 24, 26), wie beispielsweise eines hydraulischen Lenk- oder Bremskreises, dient. Durch die Fahrzeugräder wird ständig eine Hilfshydraulikpumpe angetrieben. Steuermittel sorgen dafür, daß bei einem Ausfall der durch die Haupthydraulikpumpe (12) erfolgenden Druckversorgung des hydraulischen Abnehmers (20, 24, 26) automatisch eine Druckversorgung durch die Hilfshydraulikpumpe erfolgt. Als Hilfshydraulikpumpe dient eine Hilfspumpe (30) mit veränderbarer Fördermenge, die an den Druckbedarf angepaßt werden kann. Zu diesem Zweck sind Steuermittel vorgesehen, die die Hilfspumpe (30) in Bereitschaftsstellung, bei der keine Hydraulikflüssigkeit gefördert wird, bringen, sofern eine Druckversorgung durch die von der Antriebsmaschine (10) angetriebene Haupthydraulikpumpe (12) erfolgt. Bei Ausfall der Haupthydraulikpumpe (12) wird die Hilfspumpe (30) automatisch in Arbeitsstellung gebracht, in der sie die erforderliche Hydraulikflüssigkeit an die hydraulischen Abnehmer (20, 24, 26) abgibt. Hierbei kann sichergestellt werden, daß die Hilfspumpe (30) mit voller Leistung pumpt, wenn die Haupthydraulikpumpe (12) nicht arbeitet. <IMAGE>

IPC: G01R19/02
Filed: 1992-06-05
Abstract: An AC RMS voltmeter has two RMS converters, (4,5) of the type where the RMS value of the output is proportional to the RMS value of the input. The input signal is coupled to a first RMS converter (4) of the analog variety having good high frequency response but with a short time constant. Its output is allowed to track the input at low input frequencies. The output of the first RMS converter is digitized by an analog-to-digital converter (14) and operated upon by a second RMS converter (5). The sampling rate of the A/D converter need not be high enough to operate at the highest frequencies applied to the voltmeter, since these are converted to DC by the first RMS converter. The time constant of the second RMS converter is selectable. The first RMS converter converts the input voltage to a DC component and an AC component. The second RMS converter combines these to a single DC component. A third RMS converter (10) is coupled to the output of the first RMS converter and is used to control the auto-ranging logic (12).

Abstract: Voltage slew-rate control for inductive load (20) connected to the drain (18) of an insulated gate enhancement mode field effect transistor (12) is disclosed. The voltage slew-rate control is accomplished by incorporating a current integrator (26) between the gate and drain of the field effect transistor, thereby effectively annihilating the capacitance of the field effect transistor which has heretofore proven to be generally responsible for instability and oscillations when slew-rate control is attempted in such a circuit. The current integrator (26) includes a capacitor (28) and a current source (32) in circuit with a high speed unity gain buffer amplifier (34). The buffer amplifier (34) preferably has a low impedance through the frequencies of interest to prevent the natural resonances of stray capacitances with the inductive load.

Abstract: s Communication systems, such as radiotelephone systems, allow only a limited number of subscribers. Cellular systems which use directional antennas both at the base stations and at the mobile stations do not make optimum use of the available frequencies. A communication system which uses phased array antennas at both the base stations and the mobile stations ensures a better utilization of a predetermined frequency range, suppresses multi-path effects, and is less sensitive to interference.

Abstract: A computer-controlled printing system includes a host computer, an intelligent printer and an intelligent post printer processor. The print job is controlled by defining print data, printer control data and printer post processor control data in a print data stream from the host computer. The print data and printer control data are read at the intelligent printer. The intelligent printer executes the print control data to print the print data on a print medium. The printer also determines if there is post processor control data in the print data stream and, if so, sends the post processor control data from the printer to the intelligent post processor. The post processor reads the post processor control data, and executes the post processor control data to perform selected modification of the print medium. Selectable modifications of the print medium at the post processor include predetermined fixed printing of images, symbols or text, perforation of the print medium, cutting of the print medium, or user defined modifications of the print medium.
