Abstract: In a magnetic disk apparatus in which heads integrally having write heads and read heads are arranged correspondingly to data surfaces of plural media, servo information including phase servo patterns is written discretely in a track direction onto the data surfaces of the plural media. For this reason, at first, displacement amounts of the read heads with respect to the write heads are measured in each head and each cylinder position of the media. Next, phases of the phase servo patterns are adjusted so that relative displacement amounts between the reads heads are eliminated in each head and each cylinder position of the media, and the phase servo patterns are written.

The driving method includes a first step of driving the piezo-electric element so that a meniscus of inks is receded from an initial position of the nozzle to a first position within the nozzle, a second step of driving the piezo-electric element so that the meniscus quickly advances from the first position to a second position within the nozzle, and a third step of driving the piezo-electric element so that the meniscus slowly advances from the second position to the initial position. A particle quantity of ink particles is changed by changing a movement quantity from the first position to the second position in the second step.

Abstract: This relates to a method of switching service profiles of a terminal apparatus from one to another and the terminal apparatus itself. The method easily switches service profiles of the terminal apparatus from one to another even from a remote place according to switching conditions such as a switching time. A terminal apparatus is connected to a network 8. The terminal apparatus has a service-state detector 1, a call controller 2, an initialization unit 3, a memory 4, a timer 5, a data registration unit 6, a card reader 7, and an I/O controller 9. The memory 4 stores service profile identifiers (SPIDs) and switching conditions such as a switching time. When the switching conditions are met, a present SPID is switched to a given one, the terminal apparatus is reset, and an end point initialization request is made to the network 8. An end point is initialized, and a service profile for the given SPID is allocated to the terminal apparatus.

Abstract: A simulator apparatus for a combined simulation of electromagnetic wave analysis and circuit analysis, which is configured to produce stable solutions with a smaller amount of processing loads. An electromagnetic wave analyzer calculates magnetic field at a simulation time tem01 and then electric field at another simulation time tem02 thereby performing a transient analysis of electromagnetic waves. A circuit analyzer solves the given circuit equation at still another simulation time tcs that is incremented by a variable time step size &Dgr;tcs determined in accordance with the circumstances. A current source data transfer unit compares tem01 and tcs, and if their difference falls below a time difference threshold &lgr;1, it calculates current source data for the equivalent circuit, based on the magnetic field obtained by the electromagnetic wave analyzer. The current source data transfer unit then transfers the resultant current source data to the circuit analyzer.
