摘要:
The navigation device of the invention includes a main processing unit provided with a CPU and storage means; a sub-processing unit connected to the main processing unit; connectors for connecting the main processing unit and the sub-processing unit; and functional components connected to the sub-processing unit. In this case, even when the specifications of the various functional component (s) connected to the sub-processing unit are different, by designing and manufacturing the sub-processing unit in conformance with each component, the main processing unit can be designed and manufactured as a general-purpose (standardized) product. Therefore, not only is the mountability of the navigation device improved, but also the cost thereof is reduced.

A guidance system using a telephone number and other information on a subscriber of that telephone number so as to be input and checked, whereby, retrieval and guidance by inputting the telephone number is properly performed. The system has a memory for storing specific information for specifying at least a telephone number and a subscriber and information on a point of the subscriber, an input device means for inputting the specific information for specifying the telephone number and subscriber, a retrieval mechanism for retrieving information on the point of the subscriber on the basis of the telephone number input by input means or specific information for specifying the subscriber, an output controller for controlling an output of information on the point of the subscriber retrieved by retrieval means on the basis of the inputs of the telephone number and the specific information for specifying the subscriber, wherein information is retrieved for a point of the subscriber of the hit telephone number by inputting a telephone number and according to classification of the subscriber whether the subscriber is a private subscriber, a facility, or an entrepreneur of firm, shop or the like. The invention further controls an output of personal information on a condition that a name of the subscriber is input when the subscriber is a private subscriber.

A navigation unit having a gyro sensor mounted thereon. The unit includes a mounting mechanism for changing the mounting direction of the gyro sensor so that the rotation detecting axis of the gyro sensor may be vertical, i.e. normal to a vehicle. In one embodiment, the navigation unit includes a support device for supporting the gyro sensor rotatably with respect to a casing. The gyro sensor may be supported in a rocking manner in the casing, and mounted to be changed between a first mounting direction and a second mounting direction perpendicular to the first mounting direction. In the preferred construction, the gyro sensor has a first pin and a second pin, and the casing has a first guide groove for receiving and guiding the first pin, and a second guide groove extending perpendicular to the first guide groove for receiving and guiding the second pin. The second guide groove provides a rocking center for the gyro sensor.

A vehicle navigation system includes a simulated run mode along with a normal navigation mode. In the simulated run mode, a simulated present position is calculated to move in accordance with simulated motion so that route guidance information is presented to the viewer in the same manner as during actual navigation. The simulated motion may be increased or decreased, may be stepped or continuous, and/or may be controlled in accordance with stored speed information on the roads of the route.

In an electronic controller for an automatic transmission having at least one driving circuit incorporating a switching device for driving a solenoid used as an actuator, at least one monitor circuit for detecting an abnormal state of the actuator, and a control section connected to these circuits, an emergency power cutoff circuit is provided between the solenoid driving circuit and the positive terminal of a battery (solenoid driving power source). The switching operation of the emergency power cutoff circuit is freely controlled to effect fail-safe control on the basis of a signal which is output from a microcomputer if, for example, the switching device in the controller malfunctions by short-circuiting.
摘要:
A lamp output protective circuit for an electronic controller having a first npn transistor connected to an output terminal through which a lamp is supplied with electric power, a resistor connected between the emitter of said first npn transistor and the ground, and a second npn transistor having its collector connected to the base of the first npn transistor, its emitter to the ground and its base to a point between the emitter of the first npn transistor and the resistor. The base of the first npn transistor and the collector of the second npn transistor are connected to a signal line of the electronic controller connected to a power source. The base current of the first npn transistor is controlled with the second npn transistor and the resistor in order to cut off the flow of excess current in the first npn transistor in such a manner that the second npn transistor is turned on to bypass the base current of the first npn transistor when a certain voltage is applied to the base of the second npn transistor in response to the emitter current of the first npn transistor. The resistor can be made negligible compared with the lamp resistance, enabling the first npn transistor to be protected without reducing the illumination of the lamp.
摘要:
A multiple access communication system with a multi-channel construction and applicable to a local area network (LAN). In a broadband LAN, channel assignment is agreed upon by two nodes which are to hold a communication therebetween so that a channel assigned may be continuously occupied by those nodes. The system makes it possible to perform channel assignment and channel interchange which are based on fully decentralized control. In addition, the system accommodates communications on those traffics which are entirely different in nature from each other, e.g. those in which analog and digital informations are mixed together.
摘要:
A shift register of the type capable of performing shift operations by changing the access of a random access memory, which is capable of performing the operations at a high speed, with respect to the address for reading data and the output of a counter, the input to which is a clock pulse. In order to increase the operations of the shift register, the operation of the address is performed in a power form or each input data is written at two different addresses of the random access memory.
