PROCESS FOR PREPARATION OF POROUS CARBON PLATES Porous carbon plates are made by forming a sheet from a stuff mixture comprising 65-90 weight parts of a carbon fiber-forming organic fiber and 10-35 weight parts of a pulp according to a paper-making method; impregnating the sheet with a solution of an organic polymeric substance to prepare an impregnated sheet; subjecting the impregnated sheet to an oxidizing treatment; and then carbonizing the infusibilized sheet at a temperature of at least 800.degree.C in an inert gas atmosphere.

[Auslander, Marc Alan, Cocke, John, Hao, Hsieh Tung, Markstein, Peter Willy, Radin, George] @ A mechanism for performing a run-time storage ad-dress validity check within one machine cycle. The mechanism, functioning together with an intelligent compiler, eliminates the need for hardware implementation of a storage validity check. More particularly, the mechanism performs its function in one machine cycle in the event that a trap exception does not cause an interrupt. In the rare instance when an interrupt is necessary, a number of machine cycles will be impacted. The mechanism comprises a minimum amount of logic circuitry (52) for determining the trap condition operating in conjunction with conventional, previously existing compare, branch instruction testing, and interrupt generation circuitry.＜img id="iaf01" file="imgaf001.tif" wi="80" he="92" img-content="drawing" img-format="tif" inline="no" /＞

[Stahl, Torbjorn, Hektoen, Per, Karlsen, Oystein] @ The present invention provides a method for making overhead projection transparencies. According to the invention there is arranged a first web (1) of a thin transparent plastic film on a second web (2) of paper, said first web (1) being attached along one longitudinal edge thereof by means of a line of adhesive (3), the upper face of the first web having a writable surface and the lower face thereof having a non-writable surface. In the longitudinal direction of the webs on first (B) of two sections of said writable surface of the first web (1) information may be written, e.g. in the form of diagrams, text etc. to be shown by overhead projection, while leaving the second section (A) blank. Thereafter the second web (2) or parts thereof (5, 8, 9) are removed from the first web, whereafter the assembly of the first web (1) and the possible remainder (6) of the second web is folded such that the writable surfaces of the said two sections face each other, said writable surfaces being heat weldable to each other, after which the said assembly is fed through a heat sealing means to weld the said two sections together to produce the overhead transparency.The first and second webs may be provided as a continuous form. the second web having marginal edges with feeding holes for engagement with a feeding mechanism of a data printer or data drawing machine, suitable providing multicolour information on the said writable surface.＜img id="iaf01" file="imgaf001.tif" wi="64" he="73" img-content="drawing" img-format="tif" inline="no" /＞

[Tomikashi, Minoru, Kishi, Norimasa, Suzuki, Tadashi, Futami, Toru] 2 Takara-cho, Kanagawa-ku, Yokohama-shi Kanagawa-ken, JP A receiver is applied to optical communication using an optical pulse signal carrying data which is cyclically updated. The optical signal is converted to a corresponding electrical pulse signal. The data is extracted from the electrical signal. The extracted data from successive cycles are compared. In response to the result of comparison between the data, a determination is made as to the number of cycles in which the extracted data is at a given value. When the determined number of cycles reaches a variable preset number, a previously used data value is replaced by the given value. The amplitudes of the electrical signal pulses are compared with a reference level. The preset number is varied in accordance with the result of comparison between the pulse amplitudes and the reference level.
