Abstract:
A SVC control section detects a bus voltage from an instrument transformer, and adjusts reactive power generated by a SVC according to the detected bus voltage. A cooperative control section generates a control command for controlling the interconnection and parallel-off of a phase lead capacitor and a phase lag reactor on the basis of the amount of reactive power generated by the SVC and the bus voltage detected by the instrument transformer and a voltage sensor. A voltage comparator compares the bus voltage with a predetermined threshold voltage set to a voltage lower than a lower limit value of a steady state fluctuation range of the bus voltage and outputs the comparison result to a circuit breaker control section. When the bus voltage is lower than the threshold voltage, the circuit breaker control section locks the control command from the cooperative control section.

The first constant-temperature fluid supply apparatus has an input side to which a cooling fluid not controlled in temperature is supplied, and an output side from which a first constant-temperature fluid having a stable temperature is supplied. The second constant-temperature fluid supply apparatus has an input side to which the first constant-temperature fluid is supplied, and an output side from which a second constant-temperature fluid having a more stable temperature than that of the first constant-temperature fluid is supplied.

Abstract:
A data mining apparatus is disclosed for finding a useful association rule from among a large number of association rules discovered through data mining by setting evaluation criteria of the association rules which differ depending on the user's purpose. The data mining apparatus includes an association rule generator which forms and outputs an association rule file based on data items stored in a data base, an evaluation criterion assignor which outputs an evaluation criterion file based on the evaluation criterion assigned by the user, an association rule evaluator which calculates an evaluation value based on the evaluation criterion file and updates information about the association rules in the association rule file. The data mining apparatus further includes a performance result display which displays the re-evaluated value information of the association rules in the association rule file, re-arranges display order, limits the association rules to be displayed, and then displays the re-arranged and limited association rules.
Abstract:
A toner for dry electrophotography comprises a binder resin, a metal complex compound (A) of an aromatic hydroxycarboxylic acid having a lipophilic group, and a metal complex salt-type monoazo dye (B) having a hydrophilic group. The compound (A) functions to enhances the negative triboelectric chargeability of the toner, and the dye (B) functions to leak an excessive charge of the toner, so that the toner is caused to have a uniform and sharp triboelectric charge distribution. As a result, the toner involves little liability of causing "tailing", an irregularity caused by undesirable toner scattering.
Abstract:
A CTP system is provided, which allows its continuous use even if some of laser diodes located at dispersed sites are in a non-light emitting state due to breakage or the like. In the case where some channels are in the non-light emitting state, channel-by-channel exposure data is generated to describe the way that exposure should be performed by use of specific light-emitting channels that are determined by the locations of non-light emitting channels, while an exposure head is moved also through (a) complementary interval(s) before and/or after a standard interval, the standard interval being the interval the exposure head is moved through in normal mode. Then, the transport unit moves the exposure head through the standard interval and through the complementary interval(s), during which period the exposure controller causes the specific light-emitting channels to emit exposure light according to the channel-by-channel exposure data, thereby forming an exposed area.
Abstract:
In the semiconductor device manufacturing method of the present invention, first, the emissivity of a wafer placed in a chamber is measured. Then, the fluctuation rate of a wafer physical quantity that fluctuates in association with the given thermal energy is calculated based on an estimate expression, which are obtained in advance, presenting the relationship between the thermal energy quantity emitted from the heat source for heating the wafer, wafer emissivity and the wafer physical quantity fluctuation rate and on the measured emissivity. Subsequently, the processing time for the physical quantity to be a specific value is calculated based on the calculated fluctuation rate. Then, the thermal process is conducted for the calculated processing time.
