Title: Fail bit memory writing system
Inventor: UCHIDA YOSHIO
IPC: G11C29/00
Filed: 1986-09-26
Abstract: PURPOSE:To reduce a necessary address area and reduce the storage capacity of a fail bit memory by designating the write address of the fail bit memory with a signal obtained by eliminating specific bits of the read address designating address signal of a memory device to be checked. CONSTITUTION:When the memory device to be checked is checked, data in the address designated by address signals 18x and 18y of the memory device to be checked is read out and is compared with an expected value. If this comparison results in disaccord, a fail write signal 22 is generated because bits in this address are fail bits. Consequently, data '1' is written in the address of a fail bit memory 10 designated by a signal 12 at this time. Since plural mats of the memory device to be checked are compressed into one mat and fail bits are marked in this form, the storage capacity of the fail bit memory 10 is considerably reduced in comparison with the storage capacity of the memory device to be checked.

Title: Navigation system with function for calculating return path
Inventor: NAKAJIMA MASAHIRO
IPC: G08G1/0969
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To obtain a navigation system wherein a road on which a vehicle may travel with high probability can be determined accurately when a return path is calculated after the vehicle deviated from an optimal path. SOLUTION: A link existing within a predetermined range around the current position of a vehicle is selected (S6) and the angular difference θ between the orientation of vehicle and the orientation of link is calculated (S7). When the angular difference θ is smaller than a preset threshold value (S8), a link corresponding to the road, on which the vehicle may be traveling possibly, is specified (S10). A new optimal path is then determined using the specified link as a link for starting the calculation (S12). Since the type of road corresponding to the specified link can be determined even when a high way runs in parallel with a free way, a more practical navigation system can be realized.
