摘要： Nickel powder herein disclosed is characterized in that it has an average particle size as determined through the observation by a scanning electron microscope (SEM) ranges from 0.1 to 1 &mgr;m and that the D5 0 value as determined by laser diffraction-scattering particle size distribution analysis and the average particle size as determined by SEM observation satisfy the following relation represented by Formula (1): 1≦[(D5 0 value)/(average particle size as determined by SEM observation)]≦1.8  (1) The nickel powder is highly dispersible in an organic vehicle during the preparation of a conductive paste because it has low agglomerate properties and it is in an approximately monodispersed condition and the nickel powder is particularly suitable in the preparation of a conductive paste for use in making a thin internal electrode of a multilayer ceramic capacitor, which is free of any projection, because of it sharp particle distribution.

摘要： In response to a transfer request, for which a loading time at a transfer source and a loading time at a transfer target are designated by a production controller, there is created a transfer scenario, which contains a basic transfer (From) from the transfer source to a buffer near the transfer target, for example, and a basic transfer (To) from the buffer to the transfer target. In order that the basic transfers (From, To) may be able to be executed, the buffer is reserved, and a transfer vehicle is allocated. The time period for the transfer vehicle to run to the transfer source or the buffer and the time period for the transfer vehicle to run from the transfer source or the buffer are estimated to assign a transfer command to the transfer vehicle. The possibility that the loading and the loading time may deviate from a designated period is evaluated. In case this possibility is high, a production controller is informed that a just-in-time transfer is difficult.

摘要： An optical head is composed of an objective 2, a composite diffraction element 3 having six areas divided by three parting lines 3a to 3c; and a substrate 5 on which a light-emitting element and a plurality of light-receiving elements are arranged. A focus and a tracking error signals are generated based on signals from the light-receiving elements that receive those of a plurality of luminous fluxes divided by the composite diffraction element 3 which result from passage through the portion between the parting lines 3b and 3c. In generating the tracking error signal, signals from the light-receiving elements that receive luminous fluxes resulting from passage through the outside of the parting lines 3b and 3c are used to correct an offset in the tracking error signal caused by the movement of the objective.

摘要： A method for preparing nickel fine powder is herein disclosed, which comprises the steps of mixing an aqueous sodium hydroxide solution comprising, on the basis of the total weight of the sodium hydroxide present in the aqueous solution, 75 to 85% by weight of liquid caustic soda as specified in JIS K 1203 and 25 to 15% by weight, in total, of at least one of sodium hydroxide as specified in JIS K 8576 and solid caustic soda as specified in JIS K 1202, with an aqueous solution of nickel sulfate to form nickel hydroxide, then reducing the resulting nickel hydroxide with hydrazine and recovering nickel fine powder produced. The nickel fine powder prepared by the method has an average particle size of the primary particles ranging from 0.1 to 0.9 .mu.m, a D.sub.90 value of not more than 2.1 .mu.m and a tap density of not less than 3.5 g/cc. The nickel fine powder has a low degree of aggregation, a narrow particle size distribution and a high tap density and therefore, the powder is quite suitably used as a material for producing an internal electrode for a laminated ceramic condenser.
