Abstract: A road path searching apparatus applicable to a car navigation system is disclosed. Road map data with different detailedness for defining a predetermined area is stored previously in a memory device. First, nodes Nai and Nbj adjacent to each of the search nodes Pa and PB are detected based on map data of high detailedness (step 13). When nodes Nai and Nbj exist on a map of lower detailedness (steps 14, 18), a map of one level lower detailedness is selected as a map to be used in the searching process (step 19). Accordingly, as following searching process is performed based on the map data of lower detailedness, time required for processing is reduced.

Abstract: The invention relates to a dome-forming sliding gate-sealant mass such as is used for protecting the closing gate of the outlet opening of casting ladles. It has been found that the flowability of a sliding gate-sealant mass based on quartz sand and chromium ore sand can be improved if carbon in the form of a carbon black of defined fine particle size distribution is added thereto. Improved flowability ensures that the sealant mass clears the casting opening without hindrance when the sliding casting gate is opened.

Abstract: A method for making delivery gauge corrections at low mill speeds during threading and tailing out of a workpiece by varying the interstand tension of the workpiece. The tension between the last two stands is used with a desired tension and the delivery AGC by tension mode of an existing delivery automatic gauge control (AGC) to change the speed of the downstream stands. During the threading and tailing out phases, the delivery AGC by speed is turned off and set to zero. In the full run phase, the interstand regulators are changed to a tension by roll gap mode, and an existing delivery automatic gauge control (AGC) by speed is used to provide a stand speed reference for the downstream stands. In the full run phase, the delivery (AGC) by tension is turned off and set to zero. In the tailing out phase optionally, the tension between each stand is used in a similar manner to provide a speed reference change for each stand immediately downstream from where a tension controller is located.

Abstract: This invention is a technique for high speed transmission of packetized data. In the inventive network, each of a plurality of packet switches (103-105) is equipped with multiplexing means for generating a multiplexed data signal by multiplexing packets received by the packet switch but destined for various other packet switches in the network. A system of one or more cross connect switches (100-102) receives the multiplexed data signals and generates new multiplexed data signals by directly transposing predetermined channels of the received multiplexed signals to predetermined channels of the new multiplexed data signals such that one or more new multiplexed data signals each comprise data from a plurality of received multiplexed data signals. Further, the new multiplexed data signals are generated such that all data on any new multiplexed data signal is destined for the same packet switch. Each new multiplexed data signal is then transmitted to the packet switch for which its data is destined, where one or more multiplexed signals may be transmitted to the same packet switch.

When the above values are the same, a refresh signal is output and the DRAM (102) is refreshed. When the signals compared by the comparator circuit (5) are not the same, a refresh signal is not output, and read-write operation of the DRAM 102 is performed.
