Abstract: A system for counting overlapped newspapers delivered to a stacker which employs an optical sensor which is passive in nature. Accurate count is obtained by image analysis of the image presented by the edge of the newspaper flow as the image is focused on a linear CCD array. Definitive values are determined which are quantitative of the top profile, height, of the newspapers. The processing technique employed determines the rate of change of the height of the image and utilizes the rate of change data to output a newspaper count increment when the rate of change, derivative, of top profile height changes from a positive value to a negative value and the measured profile height exceeds a calibrated value thickness, and outputs two newspaper count increments when the measured profile height exceeds a second calibrated value thickness.

Abstract: The present invention relates to novel cell growth medium components which, when added to cell growth media, can be used as a replacement for part or all of the fetal calf serum which is currently used. The process described in the present application produces cell growth medium components which are both free from active viruses and essentially immunoglobulin-free and are stable on storage. The novel process, which is applied to Cohn fractions of blood or serum, involves suspending the Cohn fraction in chilled physiological saline, adjusting the pH to between 7 and 8, adding polyethylene glycol and then diluting the resultant liquid with water or a suitable buffered saline. Subsequently the resultant solution is pasteurised by heating, this heating being preferably done in the presence of a carbohydrate such as sorbitol. The addition of a reducing agent such as ascorbic acid prior to the pasteurisation improves the stability of the final product.

Abstract: On a GaAs substrate (11) (AlYGa1-Y)0.5In0.5P crystal layers (14) (0≦Y≦1) is formed to be lattice-matched with the substrate (11). By radiating As molecular beams on the surface of the crystal layers (14) while heating the layered substrate (11) to a temperature at which In in the crystal layers (14) evaporates, the portion near the surface of the crystal layers (14) is changed into an AlYGa1-YAs crystal layer (15) (0≦Y≦1) of a thickness of several molecules, on which layer an AlXGa1-XAs crystal layer (16) (0≦X≦1) is formed. Since the surface of the AlYGa1-YAs crystal layer (15) has been purified, the formed AlXGa1-XAs crystal layer (16) has a high crystallinity, allowing production of a light emitting diode, a semiconductor laser device and the like with high efficiency.

Abstract: Graceful degradation for digitally encoded HDTV signals is achieved by appropriately coding the image to provide a controllable degradation of chosen image characteristics, such as temporal degradation, spatial degradation, and dynamic range degradation. In the temporal degradation approach of this invention, the resolution of movement suffers when noise is introduced. In the spatial degradation approach, the spatial resolution of the image is sacrificed. In the range degradation approach, the dynamic range of the signals is sacrificed. The graceful degradation is achieved by dividing the transmitted signal into two or more parts, such as parts A, B and C. Part A is given the heaviest error-correcting code; part B is given a "medium" error correcting code; and part C the is given the least powerful error correcting code (or perhaps none at all). A receiver that is close to the transmitter most likely receives parts A, B and C. A receiver that is farther away gets a noisier signal might and, perhaps, correctly receive only parts A and B. A receiver that is at the limits of the transmitter range might receive correctly only part A. Of course, the signals of parts A, B and C are constructed in a hierarchical fashion so that part A provides basic signal information; part B augments the basic information to produce a better picture; and part C augments part A plus B to produce the highest resolution picture.

Abstract: This invention relates to a method of maintaining the integrity of changes made to a revisable form document in a shared library. This invention provides a COPY command with options for checking out and checking in a revisable form document to a shared library. The check-out option allows a single user to check out the revisable form document from the shared library and make a copy thereof in a user's private storage space. A lock is placed on the revisable form document in the shared library to prevent changes while it is checked out. Information relating the revisable form document to the copy is placed in both documents. This information is used when the copy, with the user's changes, is returned to the shared library. Updates are permitted only to the copy in the private storage space. Once updates are completed, the check-in option is used to return the copy to the shared library. Information relating the revisable form document to the copy is removed from both documents and the lock is removed from the revisable form document. The revisable form document will again be made available for check out by a single user. The check-in option also permits the copy placed in the user's private storage space to be optionally deleted after the check-in operation is completed.

Abstract: [Purpose] An object of the present invention is to provide a composition for use in a formation of transparent and electrically conductive film having a low electric resistance and a high transmittance and a method for making the film mentioned above. 
     [Composition] A mixture of inorganic indium compound and organic tin compound is combined with organic compound capable of coordinating with either of indium and tin to form an organic solution. When the mixture is heated, the inorganic indium compound and the organic tin compound coordinating partially with the organic compound react with water of crystallization of inorganic indium compound. The organic tin compound is partially subjected to hydrolysis to form an intermediate complex compound including indium and tin. This suppresses the evaporation of tin and generates a uniform film having a high transmittance and a low electric resistance. An addition of polyhydric alcohol increases the viscosity of the solution and gives a high stability to a resultant film obtained by applying the composition to the substrate and firing.
