  • Patent number: 6334080
    Abstract: A vehicle control apparatus has a control unit for controlling an engine based on an engine control program and a control unit for controlling a transmission based on a transmission control program. The control units share a predetermined control data such as an engine rotation speed as a shared data. Forwarding a data from the control unit which provides the shared data to the control unit which receives the shared data is effected through shared memories provided separately from storage areas in which all the control data to be used by the control units in respective control operations are stored. Even if the system has different configurations, the addresses to be accessed for sharing the control data between the control units are the same so that the same control programs can be used.

  • Publication number: 20010053435
    Abstract: The present invention discloses a recording material in which an ink receiving layer containing, as main components, a binder resin and microparticle silica is provided on a substrate, wherein a ratio F/R, which is a ratio of a solid content weight F of the microparticle silica in the ink receiving layer to a solid content weight R of the binder resin, is in the range of 2.0 to 7.0 and a dicyandiamide polycondensate is contained in the ink receiving layer. The recording material of the present invention has excellent water proof and light resistance properties and allows printing of full-color images thereon without the patterns, colors, texture of the substrate material surface being marred even when an ink receiving layer is provided on the substrate. The recording material can be suitably used not only in the ink jet type recording but also in the offset printing.

  • Patent number: 5903228
    Abstract: A traveling route display apparatus for a moving body such as an automotive vehicle includes a position detecting section, an output section, a display section, and a converting section. The position detecting section detects a current position of the moving body by using a signal transmitted from a satellite. The output section outputs map information including character information corresponding to a position on the map recorded on a recording medium, etc. The display section displays the map information delivered from the output section, and displays, on the map information, the current position of the moving body detected by the position detecting section. In addition, the converting section converts character information corresponding to the current position of the moving body detected by the position detecting section into voice to output it.

  • Patent number: 5469152
    Abstract: A remote control device controls an electronic system that has a number of functions. The remote control device has a limited number of function keys, and certain keys correspond to different functions of the electronic system. In order to permit discrimination of the function keys, the length of time during which the function key is actuated is employed in the electronic system. To prevent erroneous control caused by artificial interruption of the control signal, the remote control device appends one of two different time code signals to the key code corresponding to the actuated function key, whereby discrimination of the actuation time at the electronic system is made possible.
