A train control system that does not allow running by erroneously receiving a signal of a further preceding train toward the front, nor permits a following train approaching another train beyond an allowable range. The system includes an existing signal system controlling running of a preceding train and a following train based on transmission signals from existing signal transmission devices, an inter-train communications system controlling running of the following train by an inter-train communications transmission signal received from the preceding train, and a train-ID transmission/reception system that detects, using a ground-based train-ID transmission/reception device, passing of the preceding train and also acquires train information of the preceding train, and that then detects passing of the following train and also transmits the train information to the following train, thereby controlling the running of the following train utilizing either one of the existing signal system and the inter-train communications system by changing over therebetween based on the train information.

A power supply control device for a vehicle includes a plurality of electrical loadings installed in a vehicle; a feeding part configured to supply electric power to the electrical loadings; and a presumption part configured to presume an electrical power demand for operating the electrical loadings based on sign information for foreseeable operations of the electrical loadings. Electrical power supply from the feeding part to each electrical loading is adjusted based on the result of presumption by the presumption part.

The present invention is directed to a start-up control apparatus for an internal combustion engine that can further improve the start-up characteristics of an internal combustion engine. An ECU is provided that corrects a position at which the crankshaft stops or a position at which the crankshaft is predicted to stop based on a rotation state of the crankshaft immediately before stopping; switches an actuation timing of the fuel injection valve of the stopped intake-stroke cylinder, which is predicted to be in a intake stroke based on a position at which the crankshaft stops, based on the position at which the crankshaft is predicted to stop; during engine start-up, switches an ignition timing that actuates the spark plugs based on the position at which the crankshaft stops; predicts the amount of air that is drawn into a cylinder during a predetermined interval after engine start-up, based on the engine speed, the position at which the crankshaft stops, volume in a intake passage, and the number of times that the intake stroke has been carried out; and calculates the fuel injection amount for the cylinder based on the predicted amount of air.
摘要:
A valve-driving system which is applied to an internal combustion engine having a plurality of cylinders for driving an intake or exhaust valve provided in each cylinder, including a plurality of valve-driving apparatuses provided for driving valves of different cylinders of the internal combustion engine, wherein each valve-driving apparatus includes an electrical motor as a driving source for generating rotation motion; and a power transmission mechanism for converting the rotation motion of the electric motor into opening and closing motion of the valve to be driven and for transmitting the opening and closing motion to the valve through a cam or a link.
摘要:
An electrostatic breakdown prevention apparatus is disclosed which allows an electronic apparatus connected to a connector to bidirectionally transfer data at a high speed on the same signal line and prevents an electrostatic breakdown of the electronic apparatus without relying upon the structure of the connector. A signal line on an electronic apparatus body side is provided with an electrostatic breakdown preventing smoothing circuit for smoothing a signal inputted to the signal line. A connector for connection of the signal line is provided with a switching mechanism for stopping the smoothing function of the electrostatic breakdown preventing smoothing circuit when the connector is connected, but restoring the smoothing function of the electrostatic breakdown preventing smoothing circuit when the connector is disconnected.
摘要:
A rotary encoder having a slider provided with a plurality of movable contact points disposed along a circle of a certain radius at an angular interval six times as large as an output pitch of rectangular wave signal. The contact-point board is provided on the surface with a signal pattern and a common pattern. Signal pattern consists of three fixed contact points, each having two conductive layers of radial shape of the same width, disposed at an angular pitch which is three times as large as the output pitch of rectangular wave signal. These fixed contact points are disposed along sliding circle of the movable contact points, at an angular pitch which is smaller, or larger, than angular interval of movable contact points, or a multiple of it, by the output pitch of rectangular wave signal, or twice that. Common pattern is disposed insulated from the signal pattern. Overall size of the rotary encoder is small in the outer diameter, and the encoder generates three-phase rectangular wave signal.

There is provided a method of authenticating a portable data-communication terminal user in a system comprising a portable data-communication terminal and a device for authenticating a user both including a transceiver for making radio-communication to each other, the method including the steps of (a) transmitting and receiving user-authentication data between the portable data-communication terminal and the user-authenticating device to thereby carry out check as to whether the portable data-communication terminal is far away from the user-authenticating device by a distance equal to or smaller than a first distance within which the transceiver can make radio-communication between the portable data-communication terminal and the user-authenticating device, and (b) allowing the portable data-communication terminal to carry out a predetermined operation only when the portable data-communication terminal is authenticated to be located within the first distance from the user-authenticating device. In accordance with the method, only when an authorized user having both the portable data-communication terminal and the user-authenticating device uses the portable data-communication terminal, the portable data-communication terminal is allowed to carry out a certain operation. Hence, it is possible to prevent a third party from using the portable data-communication terminal without permission of the user.
