Abstract: A communication controlling apparatus includes a receiving side communication protocol identifying means for determining a candidate communication protocol for a second apparatus. If an acknowledgment response is received from the second apparatus, a communication protocol is determined to be a candidate communication protocol for the second apparatus and, if no acknowledgment response is received, operations to convert a first signal into another signal conforming to another communication protocol supposed to be adopted by the second apparatus and to transmit the other signal to the second apparatus are repeated till an acknowledgment response to the other signal is received from the second apparatus.

Abstract: A data transmission system includes a first data terminal equipment, a first modem, a transmission line, a second modem and a second data terminal equipment connected in series. In order to send a control command to the second modem, the first modem interrupts a path of transmission data from the first data terminal equipment to the transmission line. Then, the first modem sends the control command to the second modem. When the second modem detects the control commands, it interrupts a path of receiving data from the transmission line to the second data terminal equipment to avoid a dead-lock of the data transmission system.

Abstract: A rope chain formed by intertwining links of a U-shaped cross-section is disclosed, which links are formed from a wire having an interconnecting upper portion, a pair of substantially straight legs extending downwardly from the interconnecting portion, and a substantially open bottom portion or seam opposite said interconnecting portion. The substantially straight legs, results in a rope chain having a full-bodied appearance and a snugger interfit between intertwined chain links. The U-shaped configuration can produce a rope chain that uses less precious metal than if the cross-section of the wire were annular and the links themselves were of annular, toroidal configuration.

Abstract: When an input/output request of a channel adapter causes a mishit on a cache and a staging amount by a device adapter reaches a predetermined amount, the cache is set into a hit status and the channel adapter is reactivated. By receiving a hit response, the reactivated channel adapter executes an input and an output for the cache and the staging of the channel adapter in parallel. A defective/alternating track management table which corresponds to track data stored in a cache memory and has each of addresses of a defective track and an alternating track and flag information showing a link state between both of the defective track and the alternating track is provided for an input/output controller. For a retrieving request in which the defective track address is designated, the defective/alternating track management table is retrieved and the corresponding alternating track address is obtained, thereby judging the presence or absence of a registration of a hash table.

Abstract: A transmitter has a power calculation unit for calculating the power of a signal. A maximum value detection circuit determines a maximum value of an output of the power calculation unit, and a floating point transformation circuit changes an output of the maximum value detection circuit into a floating point representation. A significant bit extracting circuit extracts significant bits from an output of the floating point transformation circuit and outputs the significant bits as the transmitting signal.

Abstract: A bone-shaped plastic toy is molded with a tubular central portion and a partial spherical socket on each end of the central portion. The sockets are formed by spring fingers which deflect outwardly to receive and hold a replaceable play ball. Pets, such as dogs, particularly enjoy chewing on balls and can alternately chew on one ball, then the other. A scent can be applied to the toy to enhance its desirability and pet interest. If a ball becomes worn, it can be easily replaced. Pets can play with the entire toy, with the balls removed from the toy or with the toy without the balls, thereby offering a variety of play options for the pet and pet owner.

Abstract: A zone selection method for a mobile radio communication system selects one among many radio zones and switches a primary radio zone where a given mobile terminal exists to the selected radio zone without concentrating incoming and outgoing calls at a specific radio zone. The method prioritizes the radio zones according to the reception levels of signals transmitted from the radio zones and received by the mobile terminal as well as the performance of the radio zones including the call connection ratios and channel usage ratios of the radio zones, and then, the method selects the one having the highest priority among the prioritized radio zones.

Abstract: An apparatus and a method for selecting an access router's protocol from a plurality of protocols in a communication system including first and second access routers for transferring a packet between the access routers according to the selected protocol. The packet is originated/terminated by users having a user address assigned and accommodated in the respective access routers. Storage is provided in the apparatus for storing a protocol type of the access router corresponding to the user address. The first access router issues a protocol request signal including the user address. The apparatus receives the protocol request signal and referring to the storage, responds to the signal with the protocol type of the second access router accommodating the user having the user address included in the request signal. The first access router, selects a protocol common to the first and second access routers to transfer the packet based on the response.

Abstract: A CODEC has a DSP which can consecutively execute a plurality of algorithms without restriction of a memory capacity. The DSP performs an encoding/decoding operation on a digital signal. A program memory stores a program divided into a plurality of block programs, the program being stored on an individual block program basis. A data memory stores a set of data used for executing each block program stored in the program memory, the set of data being divided into a plurality of data blocks and stored on an individual data block basis. A program executing unit executes each block program stored in the program memory by using a corresponding data block stored in the data memory. A program changing unit obtains a new block program from an external device each time execution of one of the block programs by the program executing unit is completed so as to store the obtained new block program in the program memory.

Abstract: An emergency call control apparatus for a mobile communication system does not disconnect, in a handoff, an emergency call from a mobile station in a service zone to which the mobile station has moved even when the radio channels are congested in the service zone. When a channel securement requesting unit in a first base station controller receives an emergency call from the mobile station, the channel securement requesting unit requests a second base station controller associated with a service zone adjacent to a service zone of a first base station to secure a radio channel. In the second base station controller, a securing unit secures an idle radio channel. When the mobile station engaging in an emergency call moves into the adjacent service zone, a connection requesting unit in the first base station controller requests the second base station controller to make a radio connection between the mobile station and the second base station through a radio channel secured by the securing unit.

Abstract: Artificial aquifers for hydrologic cells are used to recover hydrocarbons from carbonaceous formations. Artificial aquifers of a hydrologic cell for primary or enhanced oil recovery are constructed through the use of a conventional hydrofrac technique to make a pair of vertical extensional fractures across two parallel horizontal boreholes. Hydrocarbons move under a pressure gradient from a source aquifer to a sink aquifer. In another arrangement, artificial aquifers for exploitation of tar sands and gas hydrates are constructed through the removal of hydrocarbons which plug the pore space of the host rock. Hydrocarbons are induced to move vertically across a very large cross-sectional area from a source aquifer to a sink aquifer.
