Abstract: PROBLEM TO BE SOLVED: To provide a means for reducing reflection noise for achieving an inexpensive bus configuration even in a high speed network.
SOLUTION: The differential signal transmission system adopts a bus configuration where two wires BP and BM of a differential trunk cable each having a characteristic impedance Z1 are connected to a plurality of differential branch cables each having a characteristic impedance Z2, the lines BP, BM are each interconnected by a resistor R1 at both ends of the differential trunk cable, the resistance of the resistor R1 is selected to be a value close to the impedance Z1, a differential signal transmission circuit differentially transmits a signal by using a transistor with an ON-resistance R3, a voltage of input differential signals in a differential signal reception circuit satisfies a prescribed voltage Vmin or over, and a resistor R2 is inserted in the vicinity of a branch point between the differential trunk cable and the differential branch cable so as to reduce the reflection noise from the differential branch cable.

Abstract: PROBLEM TO BE SOLVED: To gather driving information for deciding an automobile insurance premium at a low cost.
SOLUTION: Data indicating automobile driving characteristics by a driver are gathered by an on-vehicle computer and the data are recorded in a user ID card. The card is read by data gathering devices 311-31n and 331-33n in gas stations and convenience stores and uploaded to a host computer 002. The host computer prepares the estimate of the insurance premium from the insurance calculation reference of each insurance company and driving characteristic information and presents it to the driver. As a result, when the driver indicates the intention of application to an insurance, it is notified from the host computer 002 to the insurance companies 201-20n.

Abstract: PROBLEM TO BE SOLVED: To simply write the individual information of a new product or the like. SOLUTION: A control device 300 and plural writers 100 are connected to a network 400, and a target device 200 is connected to each writer 100. A broadcast frame is transmitted from the control device 300, and each writer 100 adds an individual number of a serial # value stored in the frame and changes the serial # value into an individual serial number. The frame, having the individual information, is sent to the target device 200 and is set up in a memory 220.

Abstract: PROBLEM TO BE SOLVED: To write serial numbers differing for each PROM, by comparing addresses presented by storage elements storing them with those of common data, writing the common data in PROMs when both addresses are not matched with each other, and simultaneously writing the serial numbers differing for each PROM in all the PROMs connected with PROM connecting parts when matched with each other. SOLUTION: A control part 1 sets addresses, where serial numbers inputted from an input part 3 are written, in a serial number write address storage part 13, and sets the serial numbers in serial number storage parts 14A-14C sequentially from the initial value. When PROMs are connected with PROM connecting parts 10A-10B, the control part 1 sequentially reads data from a common data storage part 4, and outputs the data to be written in the PROMs and the addresses to a data output part 5 and an address output part 6. Based on the comparison result by a comparator 7, a selecting part 8 outputs the common data outputted by the data output part 5 or the serial numbers stored in the serial number storage parts 14A-14C.

Abstract: PROBLEM TO BE SOLVED: To realize a multi-task programming environment capable of mutually requesting a processing between processors in a multiprocessor system provided with plural processors having no inter-processor exclusive control function and a shared memory. SOLUTION: At the time of outputting a processing request to the other processor, an inter-processor communication means 105 in the request source processor exclusively secures a transmission buffer 111 from a transmission buffer pool 109 and writes transmission data in the buffer 111 and an inter- processor interruption function 107 transmits the processing request to the other processor for receiving the processing request. At the time of receiving the processing request from the other processor, the processor receiving the request executes processing based on the data stored in the buffer 111, informs the processing request source processor of the end of processing. At the time of receiving the processing end information from the other processor, the processing request source processor exclusively releases the buffer 111.
