Abstract:
In a solution for electroplating Cr in which the source of Cr ions is an aqueous equilibrated solution of Cr (III) thiocyanate complex, the improvement comprises a buffer in the solution which provides one of the ligands for the complex. The buffer is an amino acid, peptide, formate, acetate or hypophosphite. Specifically the amino acid is glycine, aspartic acid, arginine or histidine. The deposition of Cr is facilitated at high current densities, both by catalytic effect of the thiocyanate and by the intimate buffering at the cathode by the amino acid released from the Cr atom as it discharges onto the cathode.
Abstract:
A magnetic disk member for a memory disk file usable in a data processing system includes an eccentric multilobed triangular center locating hole to facilitate concentric mounting of the locating hole centerlines in a multiple disk pack memory. The disks are centered in a disk pack by placing onto a drive hub having ribs to match the lobes.
Abstract:
The disclosure is directed to the circuitry and monolithic semiconductor structure of current Hogging injection logic configurations. More specifically the disclosure relates to a semiconductor arrangement for the basic components of a highly integratable, logic semiconductor circuit concept predicated on multicollector inverter transistors which are fed by means of a carrier injection into their emitter/base zones.
Abstract:
Method of recording with a stream of marking fluid drops in which a predetermined plurality of successively formed drops in streams each has the same electrical charge induced therein so that, subsequently subjected to an electrostatic field, all drops of one common by charged plurality with impact a record member at approximately the same spot. Drop charges are induced therein by asynchronously applied charging signal levels, each of which has a duration functioning the drop formation frequency and equal to at least two drop periods.
Abstract:
A selection criterion appropriate for searching for a web service in UDDI. A provider (10) that provides web services collects result information, which will be used to judge the quality of provided web services, and sends the information to a UDDI site (20). The UDDI site (20) manages this result information and, in response to a web service search request from a requestor (30), returns a searched web service and result information on the web service.
Abstract:
@ An electronic funds transfer system (EFT) is described in which retail terminals located in stores are connected through a public switched telecommunication system to card issuing agencies data processing centres. Users of the system are issued with intelligent secure bank cards, which include a microprocessor, ROS and RAM stores. The ROS includes a personal key (KP) and an account number (PAN) stored on the card when the issuer issues it to the user. Users also have a personal identity number (PIN) which is stored or remembered separately. A transaction is initiated at a retail terminal when a card is inserted in an EFT module connected to the terminal. A request message including the PAN and a session key (KS) is transmitted to the issuers data processing centre. The issuer generates an authentication parameter (TAP) based upon its stored version of KP and PIN and a time variant parameter received from the terminal. The TAP is then returned to the terminal in a response message, and based upon an inputed ./... PIN, partial processing of the input PIN and KP on the card a derived TAP is compared with the received TAP in the terminal. A correct comparison indicating that the entered PIN is valid. The request message includes the PAN encoded under the KS and KS encoded under a cross-domain key. Message authentication codes (MAC) are attached to each message and the correct reception and regeneration of a MAC on a message including a term encoded under KS indicates that the received KS is valid and that the message originated at a valid terminal or card.
