  • Patent number: 10518783
    Abstract: Control can be continued so that control of automatic driving is not canceled even in a non-average specific road environment. An automatic driving control device, which controls an actuator of a vehicle in order to automatically travel on a road without driver operation through the use of an external surrounding recognition sensor for recognizing external surroundings and information from the external surrounding recognition sensor, has a learning recording device for recording external surrounding recognition information and vehicle status information when the driver is driving, an output comparison device for comparing the information recorded in the learning recording device with the processing results when the information recorded in the recording device is processed by the automatic driving control device, and a control parameter setting device for setting control parameters so that the results compared by the output comparison device approach the driving of the driver.

  • Patent number: 4344129
    Abstract: A data processor system is capable of operating in a first mode comprising a computer mode so as to carry out data processing functions and is also capable of operating in a second mode comprising a sequencer mode so as to carry out high speed sequence operations on the basis of programmed sequences. A high speed change between the computer and sequencer modes can freely be effected by executing mode change instructions so that the data processor system performs the duplex functions of a computer and a sequencer.

  • Patent number: 4317171
    Abstract: An LSI microprocessor comprising an instruction fetch portion and an instruction execute portion which fetches an instruction and executes an instruction independently of each other under a microprogram control, a pipeline control being made while synchronizing the portions, the instruction fetch portion containing therein an error processing circuit, which receives an external memory error signal concerning a main memory and an internal protect error signal and which delivers a reset signal for clearing a microprogram counter and starting an error processing microprogram.

  • Patent number: 4079440
    Abstract: Disclosed is a printed circuit board loaded with electronic circuits, the board having at least two connector plugs for power supply, one is relatively long while the other is relatively short. These connector plugs are connected to each other through an impedance element. During an insertion of the board to a power line, the longer connector plug gets in contact with the power line earlier than the shorter one, while, during the withdrawal of the board from the line, the longer connector plug leaves the line later than the shorter one.
