A cleaning and drying-preventing method including: positioning a nozzle in a container such that a funnel-like inner circumferential surface of the container is located around a periphery of a distal end of the nozzle; sucking a liquid in the nozzle to retract a level of the liquid to a side of a supply passage; supplying a solvent into the container to form a swirl flow of the solvent turning around the distal end of the nozzle, and cleaning the nozzle by the swirl flow; supplying a solvent into the container to form a liquid pool of the solvent; and further retracting the level of the liquid in the nozzle to the side of the supply passage. A liquid layer, an air layer, and a solvent layer are formed in the nozzle in this order from the side of the supply passage, to prevent drying of the liquid in the nozzle.

In a driving circuit of a display device, a period for writing to pixels is shortened while an increase in size of an integrated circuit is avoided. In a first period of the writing period, the pixel is charged up with a gradation potential of a particular node in a node group that includes a node which is at an objective gradation potential. In the first period, a plurality of lines corresponding to the number of nodes included in the node group are connected in parallel between the particular node and the pixel. In a second period of the data-writing period, this parallel connection is cancelled and only the node corresponding to the objective gradation potential is connected to the pixel.

The present invention provides an authentication card inserted to a portable device. The authentication card 1 is inserted (installed) in a cellular phone 30 and the authentication card 2 is inserted (installed) in a PDA 40. The authentication card 1 comprises an identification code transmission unit 10 and the authentication card 2 comprises a usage restriction cancellation unit 20. The units 10 and 20 exchange the identification code by means of wireless signal and mutually authenticate the identification code mutually. In case that the PDA 40 is moved more than the predetermined distance from the cellular phone 30 and the reception level of signal from the unit 10 received by the unit 20 is smaller than the predetermined value, or the unit 20 can not authenticate the identification code of the unit 10, the unit 20 stops transmission of the usage restriction cancellation signal to the PDA 40.

Two or more media drives that cannot be detached by the user are pre-installed in an enclosure. An expansion slot member having the smaller number of expansion drive slots than the number of media drives that can be pre-installed are provided. The media drives that are installed via the expansion drive slots are installed so as to be detached by the user.

A fiber channel switch (hereinafter, FC-SW) connected to a plurality of communications devices is provided with a buffer for temporarily storing data received from servers via a first communications port, a trace data storage memory for storing trace data, and a microprocessor (MP) for sending data accumulated in the buffer to a storage control system. The MP stores the information about the data about the received data into the trace data storage memory as trace data, issues a write command to the storage control system if it is detected that trace data sending condition is satisfied, and reads out the trace data stored in the trace data storage memory and sends it to the storage control system.

A first section, a second section, and a third section are provided. A plurality of NAS head substrates are mounted in the first section, arranged along the height direction, and each oriented horizontally. A plurality of logical substrates are mounted in the second section, arranged along the width direction. And power supplies are mounted in the third section. First through third fans are provided respectively corresponding to the first through the third sections, and the flow conduit for the air blown by each of the fans is independent from the flow conduits for the air blown by other fans.

The invention improves reliability relating to the operating environment temperature and the operating time of a processor for management in a disk array device mounting the managing processor for managing the state of the device, and further realizes mounting having no bad influence on the temperature environment within the disk array device. The disk array device uses a dedicated PC for industry in the processor for management, and is constructed such that the processor for management and a computer for output used to output management information of this processor for management are separated. Further, the processor for management and the computer for output are arranged within a disk array box body in positions for preventing no flow of a ventilating wind within the disk array box body. Here, when the computer for output is used, the disk array device is set to a mode in which the computer for output is pulled out of the disk array box body and is further rotated and used.

Aligned disk drives are installed in a disk box nearly taking a rectangular shape. Every two of the disk boxes are paired and accommodated in a rack in a multi-stage form. Each pair of disk boxes are disposed with their exhaust planes opposed to each other with a gap therebetween. An air intake plane of each disk box opposite to the exhaust is disposed on a front or rear side of the rack. A draft path, having front and rear walls formed by gaps between disk boxes and side walls on left and right planes of the rack, is formed in the rack center. Exhaust fans disposed on top of the rack and having air intake ports nearly equivalent in dimension to a section of the draft path suck in air through the intake and exhaust planes and draft path, and exhaust the air outside the rack.
