Abstract: In a wide-area paging system, each of paging terminals (2-1 , ...2-N) connected to a switched communication network (1) covers a home service area and includes a processor (21) for conversion of an incoming calling signal received from the network to a paging signal unique to the home service area and transmits the paging signal to radio transmitters (3-1) located in the home service area. One of the paging terminals (2-1) includes a memory (24) for storing telephone numbers of pagers registered to wide-area paging service, and determines whether a destination pager paged by the transmitted paging signal is registered to the wide-area paging service, and reads a telephone number from the memory in accordance with the incoming calling signal from the network if the pager is entitled to the wide-area paging service. An outgoing calling signal is derived from the read telephone number and transmitted to another paging terminal either by way of an interface (25) and the network (1), or directly (26; Fig.3). To fit the system to an existing paging terminal (2A-1; Fig.2) an interface (26) can receive the output of the terminal, and a second processor (27) to which the wide-area memory (28) is attached derives the outgoing calling signals.

Abstract: An assisted character recognition process is described which utilizes the relative position of an amount from a negotiable instrument, such as a check or credit card receipt, in a sequence of such amounts and compares its relative position to the relative position of an identical amount in a sequence of amounts on a second source, such as an adding machine tape, in order to determine the order of the items; the process also establishes matching elements which may be varied in stringency during sequential iterations of the matching process whereby the relaxation of the matching criteria will sequentially result in increased matches to allow the largest possible number of matches between the "courtesy" amounts on the checks and the amounts or entries on the second source or adding machine tape. This process is especially useful for matching handwritten entries to similar entries on a second source list such as an adding machine tape, or other such printout.

Abstract: Multiple resonant tunneling devices offer significant advantages for realizing ultra-dense, ultra-high performance multivalued logic arithmetic integrated circuits. A multivalued logic adder is disclosed, wherein two numbers represented by positive digit base-M range-N words are added by two-input summation circuits  (40)  which sum corresponding digits, then the digit sums are decomposed into a binary representation by range-7 multivalued to binary converter circuits  (42) , then three-input summation circuits  (44)  sum appropriate bits of the binary representations to calculate the digits of a positive digit base-2 range-4 word whose value is the sum of the two numbers. Preferably, the decomposition to binary representation is performed by multi-valued folding circuits  (56)  which are connected by voltage divider circuitry. Preferably, the multi-valued folding circuits contain multiple-peak resonant tunneling transistors  (54) . Ripple carries are eliminated and the speed of the adder is independent of input word width.

Abstract: A system for determining selections that a user is likely to be interested in. The determination is made based on the user's prior indicated preferences. The user designates his or her preferred selections as entries in a user's preference list. Entries in the user's list are compared with entries in the other users' lists. When a significant number of matches have been found between two lists, the unmatched entries of the other user's preference list are extracted. The unmatched entries are further processed. Those unmatched entries with a high correlation to the user's preference list are presented to the user as selections in which the user is likely to be interested.

Abstract: A flexible rack member has a substantially V-shaped cam portion formed therein, and a substantially U-shaped guide slit formed on a wall of a housing. A support bar projected on the reproducing unit is formed so as to fit in the cam portion through the guide slit. Further, tray racks are formed on respective side faces of trays. Each of joint pins mounted on both end portions of the rack member is guided by a guide groove formed on each tray while being in mesh therewith. As a result, only by moving the rack member between the trays, an up-and-down movement of the reproducing unit, a movement of the reproducing unit between the trays, and an opening and closing of each tray can be carried out successively. Additionally, the tray gear member is the only drive source, and a contact portion formed on the guide groove is key to switch each operation. The describe arrangement provides an inexpensive disk reproducing device which enables the operation to be switched at an accurate timing.
