摘要:
The present invention provides a drying apparatus capable of satisfactorily drying a workpiece by using a dry vapor The drying apparatus has a control device for controlling a supply of a carrier gas and a supply of a dry vapor into a processing tank holding workpieces. A drying process carries out a carrier gas supply step of supplying the carrier gas and a mixed fluid supply step of supplying a mixed fluid prepared by mixing the carrier gas and the dry vapor alternately. A total mixed fluid supply time for which the mixed fluid supply step is executed is not shorter than 57% of a total processing time for which the carrier gas supply step and the mixed fluid supply step are executed.

A plurality of process liquid supply nozzles 10 are arranged at different levels on right and left sides of a semiconductor wafer W in a process bath 1. A discharge port of each of the nozzles 10 is directed toward the semiconductor wafer W. In accordance with a predetermined procedure, a process liquid is discharged from one or more nozzles 10 selected from the plurality of nozzles 10. In order to perform a chemical liquid treatment, a chemical liquid is discharged from the lowermost nozzle 10, for example, and thereafter, the nozzles 10 on the upper levels sequentially discharge the chemical liquid. In order to perform a rinse liquid treatment by replacing the chemical liquid in the process bath 1 with a rinse liquid, the rinse liquid is discharged from the lowermost nozzle 10 at first, for example. Thereafter, the rinse liquid is discharged from all the nozzles 10. In this manner, efficiency and uniformity in the liquid treatment can be improved.

A composite soft magnetic material having low magnetostriction and high magnetic flux density contains: pure iron-based composite soft magnetic powder particles that are subjected to an insulating treatment by a Mg-containing insulating film or a phosphate film; and Fe—Si alloy powder particles including 11%-16% by mass of Si. A ratio of an amount of the Fe—Si alloy powder particles to a total amount is in a range of 10%-60% by mass. A method for producing the composite soft magnetic material comprises the steps of: mixing a pure iron-based composite soft magnetic powder, and the Fe—Si alloy powder in such a manner that a ratio of the Fe—Si alloy powder to a total amount is in a range of 10%-60%; subjecting a resultant mixture to compression molding; and subjecting a resultant molded body to a baking treatment in a non-oxidizing atmosphere.

A CO2 recovery device includes a cooling tower including a cooling unit for bringing the flue gas, which contains CO2, into contact with water so as to cool flue gas; a CO2-absorbing unit for bringing the flue gas into contact with a CO2 absorbent (lean solution) so as to remove CO2 from flue gas; and a regenerator including an absorbent regenerating unit for releasing CO2 from a rich solution so as to regenerate the CO2 absorbent. The CO2-absorbing unit includes: a cocurrent flow CO2-absorbing unit provided in a cocurrent flow CO2 absorber, for bringing the flue gas into contact with the CO2 absorbent in a cocurrent flow so as to remove CO2 from flue gas and a countercurrent CO2-absorbing unit provided in a CO2 absorber, for bringing the flue gas into contact with the CO2 absorbent in a countercurrent flow so as to remove CO2 from flue gas.

The invention judges a total power supply/demand condition of the electricity consumers 2 as a whole according to an individual power supply/demand condition of electricity consumers 2, judges a total usable capacity of all batteries 17 according to a usable capacity of the batteries 17 of electric vehicles 10 parked at electricity consumers 2, obtains required charge/discharge amounts of all the batteries 17 according to a result of comparison of the total power supply/demand condition of the electricity consumers 2 as a whole with the total usable capacity of all the batteries 17, subjects the batteries 17 to charge/discharge controls according to the required charge/discharge amounts, the power supply/demand conditions of the electricity consumers 2, and the usable capacities of the batteries.
摘要:
In a transmission system capable of measuring packet loss ratio between arbitrary devices upon a transmission path without increasing bandwidth of an OAM frame band, a plurality of transmission devices which have been disposed upon a transmission path are provided with a frame analysis unit which receives data frames so as to analyze the type of the data frames, a count processing unit which stores the number of received frames included in the data frames into storage module provided beforehand, an output line end portion which outputs the data frames, and an OAM processing unit which calculates the packet loss ratio in the transmission path using the number of received frames. The frame analysis unit has a function which, if the data frames are OAM frames, copies the data frames and the OAM processing unit has a function which calculates the packet loss ratio using the copied OAM frames.
摘要:
A drying gas is supplied into a drying chamber in a substantially horizontal direction, an obliquely downward direction descendent from the substantially horizontal direction, or a vertically downward direction under a state where a wafer is immersed in a cleaning liquid in a cleaning tank. The wafer is moved from the cleaning tank into the drying chamber, with the drying gas being supplied into the drying chamber. At this time, the supply of the drying gas into the drying chamber is stopped, under a condition where a part of the wafer is immersed in the cleaning liquid stored in the cleaning tank. After the movement of the wafer into the drying chamber has been finished, a drying gas is supplied into the drying chamber in an obliquely upward direction ascendant from the substantially horizontal direction or a vertically upward direction.
