Title: Magnetic recording medium
Inventor: ENOKI YOSHIO
IPC: G11B5/708
Filed: 1984-03-14
Abstract: PURPOSE:To obtain a magnetic recording medium for high-density recording which has excellent adhesive strength between a magnetic layer and a base, decreases the defects of the coated film and has excellent light shieldability and surface smoothness by dispersing carbon black with phospholipid having high purity as a dispersant into an intermediate layer to be provided between the base and magnetic layer of a magnetic recording medium. CONSTITUTION:The intermediate layer of a magnetic recording medium provided with a light shieldable intermediate layer and a magnetic layer on an org. transparent film base is formed by dispersing carbon black into a high polymer binder by using phospholipid consisting essentially of at least one of phosphatidylcholine, phosphatidylethanolamine, phosphatidylcerine, inositol phosphatide and having high purity as a dispersant. The content of phospholipid is >=80%, more preferably >=90%. The amt. of the phospholipid to be added varies with the grain size and specific surface area of the carbon black to be used and the phospholipid is added preferably about 1-20pts. for each 100pts. carbon black. The dispersion of the carbon black is thus powerfully effected, the surface characteristic of the intermediate layer is improved and the satisfactory surface wettability is maintained.

Abstract: PURPOSE:To find the optimum one out of many outgoing circuits in a shortest time, by grouping a network into optional areas and giving numbers to each area and the nodes within the area to form a number controlling table. CONSTITUTION:A network is grouped into optional areas, and area numbers 0- 2 are given to those areas. At the same time, node numbers 0-3, etc. are given to nodes N0-N3, etc. within the areas. The route channel number, the type of message, the end node address of the remote side and the transmitter end node address are set within a route setting request message that is given from the transmitter end node. At the same time, an area controlling table containing the incoming circuit numbers, the area numbers and the outgoing circuit numbers is provided within each relaying node together with a node number controlling table containing the node numbers and outgoing circuit numbers. When a route setting message is given from a certain node, an optimum outgoing circuit is obtained on the basis of the end node address of the remote side with reference to the number control table through each relaying node. Thus a route is set to start the communication to the end node.

Abstract: PURPOSE:To realize fast and accurate analog-digital conversion, by finding an offset quantity digital signal based on the digital signal of an amplification signal in which the offset quantities in a positive and a negative directions are applied on a reference analog signal, and compensating the offset quantity in the digital signal of the analog signal.

A reference digital signal is expressed as values DK(E+ V) and DK(E- V), and a difference between them goes to a value + or -2DK V. A value + or -DK V in which the above value is divided by half becomes the offset quantity digital signal, and a first arithmetic means 34 calculates the signal. Assuming a measuring analog signal as Ex, a value K(Ex+ or - V) on one side of first and second outputs can be obtained by supplying the signal Ex to the amplifier means 16-18, and controlling the switching means 5-13 by control means 22, 24, 26, 28 and 29. By converting the value K(Ex+ or - V) by conversion means 14, 15 and 30, a value DK(Ex+ or - V) can be obtained.

Title: Preparation of esters
Inventor: YOSHIDA YOSHINORI
IPC: B01J27/13
Filed: 1979-04-24
Abstract: PURPOSE: To elongate the life of a catalyst for the esterification reaction, and to provide esters useful as solvents and intermediates of various compounds, economically in an industrial scale, by carrying out the vapor phase reaction of a conjugated diene compound, an organic carboxylic acid, and oxygen, under reduced pressure, in the presence of a solid catalyst.

Production of polymerized material and adsorption of a high-boiling product to the catalyst, which result in the lowering of catalytic activity, can be prevented by this process. Since the reaction proceeds at a relatively low reaction temperature and the combustion of conjugated diene compound is suppressed, the reaction temp. can be controlled easily, and the objective compound can be obtained in high yield and selectivity.

Filed: 1983-03-25
Abstract: PURPOSE:To accurately calculate density distribution corresponding to a mean value over a long time by excluding an error caused by variation within a short time, by calculating the mean value of density distribution by a signal treating circuit while repeating measurement until density distribution is converged into a predetermined range. CONSTITUTION:An X-ray tube 105 and an X-ray detector 107 are acanned in such a state that a two-phase fluid is not flowed in an arranged pipe 101 to perform measurement and the dispersion sigmaO of measured values with respect to a plurality of picture elements in the image of a stationary reference body 104 is calculated stored. The two- phase fluid is flowed in the arranged pipe 101 to collect data which are, in turn, averaged to calculate the dispersion sigma of the measured values of the stationary reference body 104 to compare the same with the dispersion sigmaO. When measurement is repeated to average projection data, noise caused by the timewise variation of void ratio distribution is set off and the dispersion sigma becomes smaller than the dispersion sigmaO. A signal treating circuit 111 repeats measurement until the dispersion sigma is brought to the dispersion sigmaO or less and the density distribution of the void ratio distribution of the two- phase fluid is calculated on the basis of the average of the projection data to be displayed by a display device 112.

Abstract: PROBLEM TO BE SOLVED: To improve cushioning work while holding an automorphic property at the time of construction. SOLUTION: A joint filler 10 is interposed on an internal angle of a presser material layer 5 and a rising part 4 of a land roof floor part 2.
