Title: Process for initiating acetylation and equipment therefor
Inventor: YAMASHITA MITSURU
IPC: C08B3/06
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To conduct a homogeneous acetylation of a cellulose without using large amounts of an acetylating agent and a reaction solvent. SOLUTION: In the production of a cellulose acetate by acetylating a cellulose with an acetylating agent in the presence of an acidic catalyst under reduced pressure while distilling gas-phase components from the reaction system, a mixture of the acidic catalyst and the acetylating agent is added to the cellulose impregnated with a reaction solvent to initiate the reaction. The contact time of the acidic catalyst with the acetylating agent before the addition of the cellulose is shorter than about 10min, and the reaction initiating temp. is about 20 to 70 deg.C.  The equipment comprises an acetylation reactor 1, a mixing means such as a line mixer 2 for mixing the acid catalyst with acetic anhydride to be fed into the reactor 1, a pressure-reducing means 3 for reducing the pressure in the reaction system, and a condensing means 4 for condensing the gas-phase components in the reaction system.

Abstract: PURPOSE:To provide a crystalline silicon film at a low cost, by forming an island type film, dots, particles, clusters, etc., which contain nickel, iron, covalt and platinum, on or under a silicon film in the amorphous state. CONSTITUTION:Before an amorphous silicon film 1 is formed, a nickel film is deposited to be 50-1000Angstrom  thick by a sputtering method, and an island type nickel region 2 is formed by patterning the film. The nickel region is annealed for 8 hours in a nitrogen atmosphere at 450-580 deg.C. In the intermediate state, nickel progresses as nickel silicide 3A toward the central part from the island type nickel film 2 in the end portion, and the part 3 through which the nickel has passed turns to a crystalline silicon. Crystallization which has started from the island type nickel film soon collides with each other, and the crystallization ends while the nickel silicide 3A is left in the intermediate part.

Title: Decoder circuit
Inventor: SANO TOUSHI
IPC: G11C11/34
Filed: 1984-03-14
Abstract: PURPOSE:To obtain a decoder circuit capable of removing the multiselect of an address by setting properly the threshold voltage of each logical gate circuit used for a decoder circuit. CONSTITUTION:Threshold voltages of an invertor circuit G31 of the 1st stage and an invertor circuit G33 of the 3rd stage are comparatively low, namely, set to a VTL. A threshold voltage of a NAND circuit G32 of the 2nd stage, that is, an even stage, is comparatively high and set to a VTH. When the threshold voltage of a transistor alone is determined in process, the threshold voltage in a CMOS circuit is decided by a size ratio (r) of an N-channel transistor and an P- channel transistor. For instance, in case of a CMOS invertor, a threshold voltage is made smaller when the (r) is made larger, and vice versa.

Abstract: PURPOSE:To kill or damage harmful microorganism such as a tick by heat without deteriorating a hose and to prevent the loss of parts with a good operability by forming an exhaust circulating air passage communicating with the exhaust side of an electric blower and the connecting port of a dust collecting chamber in a main body case and a cover body. CONSTITUTION:When microorganism such as a tick in dust stored in a dust collecting chamber 20 is killed and damaged and strilized, a hose is kept removed from a connecting port 55. A handle part 70 is held to raise an opening and closing plate 68, open an exhaust circulating air passage 66 and communicate the exhaust side of an electric blower 26 with the dust collecting chamber 20. A part of the heated exhaust air from the electric blower 26 is circulated to the dust collecting chamber 20 through the exhaust circulating air passage 74, 66, the opening and closing plate 68, a communicating part 67 and the connecting port 55 to generate a circulating air current from the electric blower 26 to the electric blower 26 again through the exhaust circulating air passages 74, 66 and the dust collecting chamber 20. Thus, the circulating air current is repeatedly heated by the electric blower 26, whereby a temperature is raised in the dust collecting chamber 20 and reaches to about 50 deg.C capable of killing the harmful microorganism such as the tick.
