Abstract: Apparatus as shown in Fig. 1 incorporates a movable dispensing head (2) provided with a supply of material which solidifies at a predetermined temperature, and a base member (10), which are moved relative to each other along "X", "Y" and "Z" axes in a predetermined pattern to create three-dimensional objects by building up material discharged from the dispensing head (2) onto the base member (10) at a controlled rate. The apparatus is preferably computer driven in a process utilizing computer aided design (CAD) and computer-aided (CAM) software to generate drive signals for controlled movement of the dispensing head (2) and base member (10) as material is being dispensed. 
     Three-dimensional objects (40a) may be produced by depositing repeated layers of solidifying material until the shape is formed. Any material, such as self-hardening waxes, thermoplastic resins, molten metals, two-part epoxies, foaming plastics, and glass, which adheres to the previous layer with an adequate bond upon solidification, may be utilized. Each layer base is defined by the previous layer, and each layer thickness is defined and closely controlled by the height at which the tip (4) of the dispensing head (2) is positioned above the preceding layer.

Abstract: A method of positioning separate read and write heads in a disk file compensates for misalignment of the heads when reading and writing data on the disk. 
     Two sets of servo information are generated for each track on the disk. These sets are radially displaced with respect to each other by a distance equal to the respective misalignments between the read and write heads at each respective track. One set is generated by the write head. The other set is generated by the write head while the read head is aligned with said one set. Thereafter, to write data on a selected track, the read head is first aligned with said one set of servo information and then data is written on said track with the write head. To read data on a selected track, the read head is aligned to said other set of servo information and then the data is read by said read head.

Abstract: A gray scale level data of each pixel is obtained as data (Mxy) taking 5 levels between 0 and 4 corresponding to the number of ejections from 4 individual discharging portions by the pseudo-halftoning processing (112). The pointer (114) directs sequentially the memories (115 to 118) every time an ejection data is set responsive to the 5 level data (Mxy). As a result, in forming a plurality of pixels sequentially, 4 individual discharging portions are used sequentially. So far, it will be appreciated that even if ejection failures occur in either of a plurality of discharging portions of the ink jet recording head, relatively high-quality recorded images are obtained and the lifetime of the recording head can be increased.

Abstract: The contrast of an electrographic image or a region of interest of an electrographic image having low contrast is enhanced by developing the electrographic image with toner using a development electrode which is biased to a potential (V b ) which has a value near the average potential (V av ) of the image but outside of the range of values of potential corresponding to image features selected for enhancement. The voltage potential of the electrographic image is measured to determine the average potential (V av ) in the region of interest. The development electrode bias is set at a potential (V b ) near the average potential (V av ) but outside of the range of potentials corresponding to the image features selected for enhancement in the region of interest of the image. When developed with toner, the toner image has enhanced contrast. If the image is a xeroradiographic image, diagnostic capability of low contrast regions can be enhanced. Used in mammography, aerial geological surveying, security, detection of mechanical stress, etc. The main idea involves use of X-ray radiation and a luminescent toner.
