Abstract: A memory rewriting system for a vehicle controller is provided. The system comprises a vehicle controller and an external rewriting device. A vehicle controller comprises a rewritable memory storing first security data. The first security data is used to determine whether rewriting to the rewritable memory is permitted. The rewriting device transfers new security data to the vehicle controller. The vehicle controller deletes the first security data and writes the new security data into the rewritable memory. Rewriting the new security data is performed by a program stored in a non-rewritable memory. Thus, the security data that is used to determine whether rewriting to the rewitable memory is permitted is rewritten with the new security data. Therefore, if the existing security data stored in the vehicle controller is invalidated, the security feature of the vehicle can be recovered. The vehicle may includes an anti-theft system.

Abstract: A memory rewriting system for a vehicle controller is provided. The memory rewriting system transfers a first program from a rewriting device to the vehicle to rewrite a second program stored in a memory of the vehicle controller with the first program. The first program is transferred as data blocks. Each of the data blocks includes a program code field, a first address field and a second address field. The program code field contains a partial program code of the first program. The first address field contains a leading address of the memory in which the partial program code is stored. The second address field contains a leading address of the memory in which a following partial program code transferred by another block is to be stored. The data blocks are assembled in the rewriting device. Each data block is may be a fixed length or a variable length.

Abstract: A vehicle anti-theft engine control device enables engine control to be continued even if the data in the memory, wherein an ID code checking result has been stored, incurs "bit change" due to noise or the like, causing the data to change into data prohibiting engine control. The control device comprises a plurality of engine start enable flags for storing information on the enable/disable state of the engine control, enable flag registering means for registering "1" (enable) in all flags in response to a start permit signal, re-registering means for registering again, when "1" has been registered in at least one of the flags, "1" (enable) in all other enable flags, and control enabling means for enabling the engine control in accordance with the registered/reregistered enable flag.

Abstract: This invention is directed to a storage container for a magnetic recording tape cartridge comprising a pair of tape hubs each having six hub-toothings located at equal space and projected radially inwardly within a drive shaft inserting hole of the hub. The container comprises an open receptacle container body having a pair of side walls, a bottom wall and an end wall connected with each of the side walls at one end thereof; a lid member connected with the receptacle container body for rotation to close the container; and a pair of hub locking members disposed in either the receptacle container body or the lid member so as to lock the hubs against rotation.
