Title: Failure diagnosis device of fuel tank for vehicle
Inventor: KIDOKORO TORU
IPC: B60K15/077
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To diagnose whether a separation film which separates an internal space of a fuel tank into a fuel chamber and an air chamber is in a movable condition or not by providing the separation film and using a physical quantity in the fuel tank in which the separation film moves vertically together with a liquid surface of fuel while it adheres closely to the liquid surface thereof. SOLUTION: A separation film 5 made of a material which is flexible and have the impermeability of fuel vapor such as polyethylene is arranged in an internal space 4 of a fuel tank. This separation film 5 separates the internal space of the fuel tank into an air chamber 6 and a fuel chamber 7 in the upper and lower parts thereof, respectively. Moreover, a fuel remaining amount detector 37 for detecting a remaining amount of fuel in the fuel chamber is provided to detect a displacement amount of the separation film 5 from the vertical movement of a detection rod 38 and convert it to a remaining amount of fuel.  The fuel tank provided with the fuel remaining amount detector 37 which detects a displacement amount of the separation film 5 is used to diagnose a failure based on a difference in integrated running distance and a difference in fuel remaining amount output which corresponds to it. That is, a displacement amount of the separation film 5 is used as a physical quantity to diagnose a movable condition of the separation film 5.

IPC: H02J7/00
Filed: 1978-03-31
Abstract: PURPOSE: To premit quick charging and prevent overcharging with a simple conconstruction of  merely providing a constant voltage circuit on the rectified output side.   
     CONSTITUTION: A diode 32 is connected between an input terminal 23, to which a secondary battery 21 is connected, and an output terminal 33, a zener diode 37 and a diode 35 are connected  between an input terminal 28, to which a rectified output 25 is coupled, and an input terminal 28,  and a resistor 29 is connected between the terminals 23 and 28. Usually, the rectified output 25 is  higher than the voltage of the secondary battery 25, and the battery 21 is charged through a  resistor 29 while at the same time the rectified voltage is coupled through the diode 35 to the load.  When the voltage of the secondary battery 23 exceeds the output voltage of the zener diode, the  diode 32 is rendered conductive, so that the charging current to the battery 21 ceases. When the  rectified voltage 25 is reduced to zero, the diode 35 is cut off, and current is supplied from the  secondary battery 21 through the other diode 32 to the load. In this way, the application of  voltage to the load and charging of the secondary battery from the rectified voltage side on one  hand and prevention of overcharing of the battery and supply of current from the secondary battery to the load on the other hand are automatically switched over to one another depending upon  the relations of voltages on various parts.
