Title: Double-length multiplier
Inventor: IKEZAWA TOSHI
IPC: G06F7/53
Filed: 1980-09-26
Abstract: PURPOSE:To achieve the multiplication of double-length bits through using one multiplier of fixed bit length, by dividing the respective digits of multiplier and mulitplicand into 1/2, by finding their partical product three times, and by multiplying it. CONSTITUTION:A prescribed multiplier A and a prescribed multiplicand B are divided into the upper priority digit and lower priority digits, namely, AM and A1, plus BM and BL respectively, and they are stored in registers 1-4. Through selectors5 and 6, the AM and BM, AM and BL, plus AL and BM are inputted selectively to a multiplier 7 of fixed bit length, where a partial product 1 CMM=AMXBM, a partial product 2 CML=AMXBL, and a partial product 3 CLM=ALXBM are obtained. Then, said partial products 1-3 are accumulated to obtained a multiplication result C=CMM+CML+CLM. Consequently, the multiplier 7 having fixed bit length achieves the multiplication of double-length bits, so that the multiplication of double- length bits, even if required occasionally, is carried out by one inexpensive mulitplier with fixed bit length.

Abstract: PURPOSE:To shorten drying time and make a drying unit smaller and simpler by crosslinking and hardening a liq. composition contg. a compound which is crosslinked one being irradiated with high energy rays and an impregnability providing high molecular compound and impregnating a photosensitive diazonium salt-contg. soln. into the composition. CONSTITUTION:A composition consisting of a compound which is not an oligomer is prepared, having 1-4 ethylenic unsatd. bonds, and it is crosslinked one being irradiated with high energy rays such as electron beams or ultraviolet rays and/ or a compound having 2-6 epoxy bonds and of a vinylidene chloride-base copolymer or a noncrosslinkable polymer of cellulose deriv. or the like as an impregnability providing compound. The composition is applied to a support and irradiated with ultraviolet rays to form an impregnable layer by polymn. A coupler-free photosensitive diazonium salt soln. is then applied to the layer and impregnated to obtain a bubble image forming material. Since no volatile solvent is used to form the layer, long-time drying with a large-sized complex drying device is not required.

Title: Apparatus for removing co2 with hot potassium carbonate
Inventor: WATABE TAKESHI
IPC: C01B32/50
Filed: 1982-07-30
Abstract: PURPOSE:To reduce the energy cost of the titled apparatus, by heating and concentrating the lean liquid of the regeneration tower with external steam via an aqueous solution of lithium halide thereby generating stripping steam. CONSTITUTION:The lean liquid from the regeneration tower 44 is heat-exchanged in the first heat-exchanger 47 with the condensed water discharged from the fourth heat-exchanger 50, and the condensed water is evaporated to generate steam, and at the same time, the cooled lean liquid is returned to the top of the absorption tower 41. The steam generated in the heat-exchanger 47 is absorbed in e.g. an aqueous solution of LiBr in the second heat-exchanger 48 to dilute the aqueous solution, and at the same time the temperature of the solution is raised by the heat of absorption. The hot solution is subjected to the heat-exchange with the lean liquid in the regeneration tower 44, and the evaporated steam is returned to the tower 44 and used as the stripping steam. The diluted LiBr solution is heated and concentrated in the third heat-exchanger 49 with external steam, and the generated steam is passed through the fourth heat-exchanger 50 to evaporate the lean liquid to the stripping steam. The LiBr solution concentrated in the heat-exchanger 49 is recycled to the heat-exchanger 48.

Abstract: PURPOSE:To obtain a connection to the entire object scene covering over plural divided viewfields by applying a connecting process of a binary pattern to a detected viewfield and at the same time executing a connecting process of a pattern on the boundary between divided detected viewfields. CONSTITUTION:A binary signal 9 of an object scene obtained from an image pickup device via a binary coding circuit is supplied to Xs and Xe detecting circuits 12 and 13 together with the X coordinate signal which is obtained from an X coordinate generating circuit 11 by an X direction scan clock 10.
