    摘要: The present invention includes crosslinked perfluoroelastomeric compositions and molded articles formed from a cross-linkable perfluoroelastomeric composition having a first curable perfluoropolymer having a cure site monomer and a second perfluoropolymer having a cure site monomer. The molar ratio of the tetrafluoroethylene monomer to perfluoroalkylvinyl ether in one perfluoropolymer is about 0 to 100 to about 65 to 35 in the perfluoropolymer. The molar ratio of the tetrafluoroethylene monomer to the perfluoroalkylvinyl ether monomer in the second polymer is about 65:35 to about 95:5 in the second perfluoropolymer. The composition further includes a curative. One fluorine-containing elastomer composition herein, having a short crosslinking time, has perfluoroelastomers (A) having a tetrafluoroethylene unit, a perfluoralkylvinyl ether unit (a) and a monomer unit (b) having at least one kind selected from the group consisting of a nitrile group, a carboxyl group and an alkoxycarbonyl group, wherein the composition has two or more kinds of perfluoroelastomers (A) having differing contents of perfluoroalkylvinyl ether unit (a).

    摘要: In an apparatus, an abnormality determining circuit determines whether a crank signal is abnormal, and a switching circuit switches an input signal to an edge interval measuring circuit from the crank signal to a cam signal when it is determined that the crank signal is abnormal. The edge interval measuring circuit measures an edge interval of temporally adjacent same-directed edges of the cam signal. A count-value control circuit identifies angular positions of a crankshaft based on the cam signal to initialize a count value of a count unit based on the identified angular positions of the crankshaft. The count-value control unit circuit changes an integral number based on a predetermined waveform pattern of the cam signal to shift the count value of the count unit as in the case of the crank signal inputting to the edge interval measuring circuit.

    摘要: In a data rewriting control apparatus, a receiving processing of storing data received from a memory rewriting device into a rotating type receiving data buffer in a RAM of a microcomputer is executed in parallel by the use of a time period required for a data writing processing in which the data is stored as writing data into a writing data buffer in the RAM and written into a flash ROM. Thus, the total time period of processing which includes a processing of receiving the data from the memory rewriting device and a processing of rewriting writing data into the flash ROM is shortened.

    摘要: In a memory rewriting apparatus, it is confirmed first that a check program is present at a head address of a storage area in a flash ROM of a microcomputer in an ECU for storing an application program, when it is determined by a boot program in the flash ROM that the application program is to be executed. The processing proceeds to the application program after the execution of the check program. Thus, it will not occur that the processing jumps to the application program when the application program is not present. As a result, erroneous operation of the ECU due to an erroneous execution of the program can be prevented.

    摘要: In an electronic control system having a CPU, a RAM and an EEPROM, an original data stored in the EEPROM is written into the RAM to be updated in a control calculation processing of the CPU. If the updated data is the type which is to be written back into the EEPROM, a writing request is issued at the same time of writing into the RAM and an address and size of the updated data are also written into the RAM as a related data. Actual rewriting of the updated data into the EEPROM is executed based on the related data in a separate data rewriting processing in response to the writing request. Thus, interruption of the application processing for the data rewriting into the EEPROM can be shortened, and the updated data can be prevented from being broken and lost even upon instantaneous power-off.

    摘要: Flash ROMs store a control program for controlling an internal combustion engine and a boot program for rewriting the flash ROMs in respective storage areas. A user breakable object area is set appropriately to the flash ROMs by a user breakable function of a UBC which a microcomputer has in an ECU. Thus, even when a reading command or a writing command is issued to predetermined addresses in the user breakable object area of the flash ROMs, the processing jumps to a predetermined other address without changing the stored therein. Therefore, a request of writing to the boot program storage area of the flash ROMs, which arises from some abnormality, can be eliminated.

    摘要: An electronic control unit includes a flash memory as a nonvolatile memory, which is capable of erasing its storage contents block by block, for storing control programs and data. An erasure processing is carried out for the storage content in each of the blocks identified by an erasure command received from an external device, and a rewrite processing is carried out to replace the erased content with a new content received from the external device. The number of the erasure processing is counted only once when the first one of the erasure commands is received for a plurality of blocks, as long as the control unit is held operative after its initial condition.
