The toner image is fixed on the paper and the whole surface of the charge retentive layer is cleaned.The electrophotographic apparatus allows selective application of a transfer bias voltage to so as to prevent at least partially undesired charge from being deposited on the charge retentive layer. The transfer bias voltage is applied only when the paper exists in the transfer region.

  • Patent number: 4171160
    Abstract: A distance measuring instrument comprising a source of coherent light and a receiver is disclosed which may be used to measure the one dimensional position of an object surface. Coherent light is directed at a predetermined angle onto the object surface and the angle at which diffusely reflected light from this surface enters the receiver is measured. This entrance angle is measured with a photosensor and a movable aperture formed by the intersection of a fixedly mounted diaphragm and a movably mounted diaphragm. By measuring the position of the movably mounted diaphragm when the movable aperture is placed so as to allow reflected light to pass from the illuminated surface to the photosensor, the entrance angle of the reflected light and hence the position of the object is determined.

  • Patent number: 4171161
    Abstract: A light source, preferably an electrical flash tube, generates a beam of light which, preferably, is collimated to provide a parallel beam output. The workpieces are placed in the beam of light to generate a shadow image. The shadow image and surrounding beam portions are projected on a screen, with intervening optical enlargement, on which photoelectric sensors are located positioned in the projected shadow image and preferably also in adjacent regions of the light beam, the outputs from the sensors being compared with each other, or with a reference, to determine relative shadow image characteristics of regions of the objects in the light beam path, the output signals being a measure of differences in characteristics, and hence determinative of orientation, size, or integrity of the workpiece material.

  • Patent number: 4171164
    Abstract: A method and apparatus is provided for formulating meat blends to a desired fat percentage by continuously measuring in a non-destructive manner the percentage of fat in meat streams while they are flowing, and thereafter blending the streams into the desired formulation. Although the meat streams are of non-uniform consistency and density, accurate blending is accomplished by including a sensor that automatically and continuously monitors the meat streams to enable corrections for such non-uniformity. Percentage fat measurements are made by passing a beam of polychromatic X-rays through the streams and measuring both the incident and attenuated beams.

  • Patent number: 4171170
    Abstract: An automatic pencil employing axial movement of a lead piece guide and a lead piece chucking mechanism. After a length of protruding lead rod is used up, the lead piece guide is caused to retract in the same amount as the wearing away of the lead rod. By pressing the tip of the lead rod against another object, the lead rod is caused to move back with the chucking mechanism. After the rod is retracted until the tip aligns with the tip of the guide, the rod and lead piece guide will be moved back. The rod will then advance when the holder is moved away from the object while the lead piece guide will be left in the retracted position due to a large friction between the friction member and the guide means. By this operation, the rod is protruded from the guide at substantially equal length to the stroke of the retracting movement.
