Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To enable the update processing of data in a document or the like having a much data amount without requiring long communication time by verifying the consistency of new data restored by exchanging a signature for the new data between one device and the other device. SOLUTION: Based on the instruction of control part 14, a document identification part 11 discriminates whether the identification information of received document is equal with that of document stored in a storage part 2 or not. When the identification information is equal, after discrimination, the document identification part 11 sends a signal to a document consistency verifying part 13 so as to request the discrimination of consistency. That document consistency verifying part 13 discriminates the equality of received document with the document stored in the storage part 2 corresponding to whether the signature information of stored document is coincident with that of received document or not.  When the signature information is coincident, the transfer start of differential information is requested to a differential processing part 12, the new document is restored based on the differential information by the differential processing part 12, and the consistency of new document is verified by the document consistency verifying part 13.

Title: Detection of analog displacement
Inventor: KOBAYASHI NOBUYOSHI
IPC: G01P13/04
Filed: 1982-07-23
Abstract: PURPOSE:To achieve a smaller size and a higher function by a method wherein combined signals obtained from two detectors in the width of a detection object are code converted as 0, 1, 2 and 3 in sequence, the preceding figure is subtracted from the subsequent figure with 0 replacing 4, which then, is replaced with 0 thereafter. CONSTITUTION:In the case of the right-ward direction, a combination signal of detectors A and B is a repeated signal of [01320132...]. When 3 and 2 in the signal are shifted to 2 and 3 respectively by a code conversion, [01230123...] is given and [32103210...] in the left-ward direction. Here, subtraction is made between the preceding and subsequent data. But before that, 0 is converted to 4 and then, after a judgement, 4 returned to 0. As a result, in the case of the right-ward direction, the signal is as given by [01234 01234 01...] and in the case of the left- ward direction, by [3210 43210 4...]. Thus, the detection of direction is possible. The signals thus code converted are inputted into a subtraction means 24 to perform subtraction between the preceding and subsequent data. The results are negative in the right-ward direction while positive in the left-ward direction and inputted into a counting means 25. The counting means 2 5 counts 1 for one figure in the combination signals [012340...] and [321043210...] and indicates counts on a display 26. Thus, the detecetion of the direction can be done in the analog displacement by the softward control with a microcomputer thereby simplifying the entire construction.

Filed: 1993-05-28
Abstract: PURPOSE:To obtain the subject compounds by effecting the reaction of methanol, methyl acetate or dimethyl ether and carbon monoxide or a combination thereof with hydrogen in the presence of a catalyst in a series of facilities. CONSTITUTION:A rhodium compound and methyl iodide are used as major catalysts to effect the reaction of methyl acetate or dimethyl ether and carbon monoxide or a combination thereof with hydrogen in the first reactor to give acetic anhydride. After most of the catalyst are removed from the reaction mixture, at least a part of the acetic anhydride formed in the first reactor is allowed to react with methanol and/or water in the second reactor to form acetic acid and methyl acetate or acetic acid.

Acetic acid is useful as a starting substance for acetate, acetic anhydride, vinyl acetate and production of terephthalic acid. Acetic anhydride is useful as a starting substance for cellulose acetate, medicines, perfumes, dyes and the like.

Title: External force offset correction system for disc device
Inventor: NAGAOKA HIDETADA
IPC: G11B21/10
Filed: 1991-05-30
Abstract: PURPOSE:To correct an external force offset even when an external force blocking a head position is large abnormally in an initial state, for example, at the closing of a power source. CONSTITUTION:An external force offset measuring/correcting device 17 sets on a D/A converter 2 a reference offset data which serves to stop a head 10 at a specified position on a disc 18 when there is no external force. A drive circuit 8 operates an actuator 9 according to a value set to move the head 10. When an external force exists, the head 10 fails to stop at the specified position and the position at which the head stops actually is transmitted to a register 16 via a reading circuit 14 and an A/D converter 3. The external force offset measuring/correcting device 17 changes a value set on a D/A converter 2 until the head 10 stops at the specified position to drive the head 10. Thus, an external force offset value is measured from the value set on the D/A converter 2 as given when the head 10 stops at the specified position.

Abstract: PURPOSE: To facilitate slurry transportation by forming mixed pigments of satin white and a cubic type precipitated Ca carbonate of a salt consisting of a copolymer of unsaturated carboxylic acids as a dispersant for mixed pigments for preparing high concn. water slurries and forming this as stable low viscosity liquid.  
     CONSTITUTION: As the dispersion for mixed pigments for preparing high concn. water slurries, the mixed pigments of satin white and a cubic type precipitated Ca carbonate at 1/1W1/5 specific ratios are made of the salt of a copolymer consisting essentially of an unsaturated monocarboxylic acid and contg. an unsaturated dicarboxylic acid, for example, the Na salt of the copolymer of 85W99mol% acrylic acid and 1W15mol% maleic acid. Therefore, the usage of the dispersant can be as small as 0.3W5wt% based on the weight of the satin white-Ca carbonate mixed pigments, and its solid concn. is 40W60wt%. These make it possible to prepare high concn. water slurries, transport slurries on account of stable low viscosity, and lower costs.
