    摘要: The process of the present invention comprises the steps of (a) a step of dissolving a condensed tannin powder in an aqueous alkaline solution, (b) a step of admixing an aqueous aldehyde solution with the aqueous solution obtained in the step (a), (c) a step of adding the aqueous solution obtained by the above step (b) to a hydrophobic solvent containing a polyether type nonionic surfactant under heating and stirring to disperse the aqueous solution in the form of droplets in said hydrophobic solvent and (d) evaporating water components from the above-mentioned droplets to form a spherical and gelled insoluble tannins. Water content of the gel can be widely controlled as 5 to 90% as compared with the conventional adsorbent and the network structure and molecular space are changed depending on the size of the metal ion to be adsorbed so that a gelled insoluble tannin which can increase an adsorption capacity of metals can be obtained. Also, when it is used as an adsorbent, it is not necessary to be pulverized and a gelled insoluble tannin having a desired particle size and water content can be obtained.

    摘要: A method for predicting printing density for use in a stencil printing in which an ink is transferred from a rotated printing drum to a printing sheet through a perforated stencil, by pressing the printing sheet and the printing drum against each other, is provided. The method comprises (a) a first step of measuring printing densities (OD) on at least two copies of print at corresponding printed portions thereof, the copies of print being obtained under different conditions of F/f, in which F is a pressing force at which the printing sheet is pressed to the drum and f is a rotation speed of the drum, (b) a second step of statistically processing the printing densities measured in the first step to obtain a function of printing density and F/f value, and (c) a third step of calculating a printing density at a desired pressing force and a desired rotation speed based on the function obtained in the second step. The function may be OD=V×{square root over ( )}(F/f)+W, in which V and W means constants that may be obtained by least-squares method.

    摘要: A sheet feeder unit being capable of separately supplying cut sheets of any thickness without causing any residual deformation. Cut sheets (11) in a pile are advanced one by one with a pair of feeding rollers (31) contacting thereto from one side thereof. A friction member (33) is disposed in the middle between the pair of feeding rollers (31) which is backed away by a proceeding cut sheet (11) thereby separating the outermost cut sheet (11) from the other sheets by the frictional force of contact therebetween.

    摘要: A network system includes a local area network to which a plurality of transmission apparatuses are connected, a gateway apparatus for connecting the local area network to a wide area network, and a plurlaity of terminal adapters for connecting the local area network to communication terminal apparatuses, and a management method therefor. Each transmission apparatus sends a transmission request of management data requesting data on the operating conditions of the connected local area network, the gateway apparatus, and the terminal adapters, acquires data on the operating conditions of the other apparatuses sent in response to the transmission request, and simultaneously displays the acquired management data, so that the operating conditions of the apparatuses connected to the system can always be monitored. Even when a communication error occurs, location of the source of the error can be easily determined without arranging a special-purpose LAN monitoring apparatus.
