摘要:
A PC card control apparatus includes a PC card connector, a card detector and an interconnection switching circuit. The PC card connector is configured to provide connections for connecting one of a first PC card compliant with specific card standards and a card-adapting card for connecting a second PC card compliant with a different card standard to the PC card control apparatus. The card detector is configured to detect connection of the card-adapting card to the PC card control apparatus and to subsequently output a detection signal. The interconnection switching circuit is configured to switch the connections of the PC card connector to connect the PC card connector to a bus interface dedicated to the second card upon receiving the detection signal from the card detector.

The present invention provides an activated clay for refining aromatic hydrocarbons such as BTX (benzene, toluene, xylene), etc., satisfying the requirements of both excellent life and excellent side-reaction-preventing property. The activated clay for treating aromatic hydrocarbons is obtained by treating dioctahedral smectite clay minerals with an acid so as to possess a BET specific surface area of not smaller than 250 m.sup.2 /g and to contain iron in an amount of not smaller than 2.5% by weight calculated as Fe.sub.2 O.sub.3.
摘要:
A suck back valve is proposed which prevents change in the amount of fluid which is sucked by the suck back valve, and which improves response accuracy of a diaphragm, together with accurately controlling a displacement amount and a displacement speed thereof. A diaphragm displaceably disposed confronting an interior of a flow passage is formed from a first membrane and a second membrane stacked on the first membrane, wherein the first membrane is sucked into contact with the second membrane through holes defined in the second membrane, by activation of a negative pressure generating source which is connected to a chamber through a passage, and wherein the form of the first membrane is maintained by the second membrane.
摘要:
The present invention relates to an arrayed recording apparatus having spare devices for replacing faulty disk drives. Each of the SCSI controllers in the arrayed recording apparatus connects to a driver/receiver and further connects to spare disk drives. Each of the SCSI controllers accesses the spare disk drive by setting a receive/enable signal effective to the driver/receiver. Unused ID numbers are assigned to the spare disks. If a disk drive develops a fault, the RAID controller RC requests the SCSI controller to replace the faulty disk drive with the spare disk drive.It is possible to attain the function of the hot stand-by system without comprising a specific spare controller.
