Next, position selective exposure (image exposure) is performed to make the potentials of the  photoreceptor 1 surface nearly zero in the exposed part and negative in the non-exposed part,  after which the images are developed by the non- magnetic toner which has been forcefully  charged positive. In the case of forming negative images, secondary charging of negative polarity  is so applied that moderate positive charges remain on the insulation layer 12 surface, after which  image exposure is performed to make the potentials of the photoreceptor 1 surface positive in the  exposed part and nearly zero in the non-exposed part, thence the images are developed by the  non-magnetic toner which has been forcefully charged negative.

Abstract: PURPOSE:To obtain intensity of an electric field high enough to attract ink droplet, by shading a photoconductor layer with a light shading layer laminatd on said layer in one body from external light, and rendering the light shading layer conductive in one direction. CONSTITUTION:Light is transmitted through only the parts of the types of a microfishe M to render a photoconductor layer 1c electrically conductive. Negative charge is injected from a transparent electrode 1b through the parts of the layer 1c made conductive, and the parts of a one-way conductive light-shading layer 1d corresponding to said parts, but the parts of the layer 1d unexposed to light retains positive charge. At that time, since a control electrode 54 is charged positively, positively charged ink mist is attracted toward a recording sheet S, and attached only to the parts of a negative electric field to print the types. The layer 1c is shaded effectively from light, by the layer 1d, and the charge is transmitted to the reverse side of the sheet S, therefore, electric field intensity enough to attract the ink droplets can be obtained.

Title: Method of measuring flow rate and digital flowmeter circuit
Inventor: UIRIAMU ETSUCHI BUANDAA HEIDEN
IPC: G01F1/66
Filed: 1986-03-13
Abstract: In a method and apparatus for generating a signal proportional to flow in a pipe using probes strapped onto the exterior of the pipe, two ultrasonic pulse trains at a carrier frequency are sent in opposite directions from one probe to the other. Two lower frequency signals are extracted from the two respective pulse trains and analyzed to detect a phase difference. The phase difference corresponds to a difference in the travel times for the two pulse trains caused by the flow velocity in the pipe. The two lower frequency signals are converted to digital data samples which are stored with reference timing data. A microelectronic processor synchronizes the two sampled waves, using the timing data, before comparing the sampled waves to determine the phase difference. The processor and associated circuitry also measure the travel times of the two ultrasonic pulse trains and generate an output signal proportional to flow based on the measured phase difference and the measured travel times.
