摘要:
A server (1) analyses the request information transmitted from a client (11) by means of a request analyzer 4 and selects the necessary image data from multiple viewpoint image data (2) to output it to an image generator (3), where image data for the requested viewpoint is generated by interpolation to be output to an image synthesizer (5). In the image synthesizer (5), a plurality of images data are synthesized in a form suitable for encoding. An encoder (6) encodes the image data at a suitable bit rate and transfers it to a network (7). The client (11) receives the encoded image data, decodes the data through a decoder (12) and outputs the decoded image data to an image processor (13), where the image data is converted into an appropriate form in conformity with a stereoscopic display format and is displayed on a display unit (14). The client (11) also includes an input unit (16) for change of the viewpoint, and transmits the request information of viewpoint alternation to the network (7) by means of a request output unit (15). Thus this system enables observation of a stereoscopic image viewed from an arbitrary viewpoint even with a mobile terminal or the like.

A video coding device capable of making coded data have a hierarchical structure, a specified area of each frame is selected. The position and the shape of the selected area are encoded, a pixel value of the selected area is encoded as slower-layer coded data, a pixel value of a whole image is encoded as first upper-layer coded data by using pixel values of already decoded images of the lower-layer and the first upper layer and a pixel value of the selected area is encoded as second upper-layer coded data by using pixel values of already decoded images of the lower-layer and the second upper layer.

An improved coated hard alloy tool having a substrate made of a hard alloy, and a multi-layer ceramic coating film provided on the surface of the substrate, the coating film including at least one oxide layer. The top several layers of the coating film are missing partially or completely in an area where the tool is brought into frictional contact with a workpiece. At least one oxide layer (such as Al.sub.2 O.sub.3 layer) is included in the missing layers. This increases wear resistance of the coated hard alloy tool.

Displacement between an actual designation position designated by a detection pen and a detection coordinates is corrected. A correction calculation section includes a plurality of processing mode determination modules, a propagation delay correction module, an inward displacement correction module, a waveform distortion correction module, and a periodical fluctuation correction module. The processing mode determination module determines a correction module according to a detection coordinate value input. Each of the correction modules includes a correction formula or a lookup table inherent to each area. According to the correction formula or the lookup table, input detection coordinate value is corrected to thereby correct the displacement between the actual designation position and the detection coordinate value.

The invention provides a method for manufacturing sintered parts, which uses as a debinder solvent a substance harmless to the human body and which can enhance the strength of an injection-molded product. Sintered parts suitable for use in industrial production processes and, moreover, extremely high in strength of injection-molded parts, can be produced by the steps of: mixing at least one of a sintering inorganic powders of a metal powder, a metal carbide, a carbon-nitride, a nitride powder and a ceramic powder, with an organic binder composed of an organic substance soluble in an alcohol series solvent and an organic substance insoluble in the same; injection-molding the composition obtained by the preceding process into a metal mold of a sintered part shape; immersing the injection-molded product obtained by the preceding step into an alcohol series solvent to elute and remove part of the organic binder; and heating the product to remove the residual organic binder and sintering the same, wherein the portion soluble in the alcohol series solvent of the organic binder accounts for 30 to 70% of the binder.

A drill is formed by a hard dispersed phase of WC and a B-1 type solid solution, and a bond metal phase of an iron family metal. The composition of the hard dispersed phase is expressed as (W.sub.a M.sub.b) (C.sub.x N.sub.y), where M represents Ti, or two or more metals, including Ti but excluding W, selected from the group IVa, Va and VIa of the periodic table, and a, b, x and y represents molar fractions which are defined by relational expressions of a+b=1, x+y=1, x>0, y.gtoreq.0 and b.gtoreq.0.4. The bond metal phase occupies at least 13 volume percent and not more than 30 volume percent of the cemented carbide.
