Abstract: PURPOSE:To make it possible to improve the reliability of wire breakage detection by a method wherein a reverse flow checking diode is provided between a connecting point of a capacitor charged through the ON operation of a main switch and a charge resistor and a connecting point of a switching element and the vehicle lamp. CONSTITUTION:When the lamp 2 is put OFF, that is, when the main switch 4 is turned ON, in a condition in which a transistor 1 is OFF, if the wire is not broken, the connecting point (a) is grounded to have a low potential through the diode 6 and the lamp 2 but if the wire is broken, the capacitor 5 is charged through the charge resistor 3 so that the contact point (a) is held at a high potential and a transistor 7b is turned ON to thereby light up a wire breakage display lamp 7c. Next, if the lamp 2 is put ON by the main switch 4, the potential of the connecting point (b) goes high and low repeatedly but when there is a wire breakage, the connecting point (b) is kept at a high potential and accordingly, the connecting point (a) is also held at a high potential and the wire breakage display lamp 7c is lighted up. In this case, the variation of such detecting potential is as high as in the order of about 12V so that the detection of wire breakage is performed accurately.

Title: Detecting device for trouble by cylinders of internal combustion engine
Inventor: TANAKA SEIGO
IPC: G01M15/04
Filed: 1985-08-30
Abstract: PURPOSE:To detect abnormality by cylinders without adding any special hardware by detecting whether a cylinder has trouble or not from the acceleration of rotation of a crank shaft right after the explosion position of each cylinder. CONSTITUTION:The rotation of the crank shaft right after the explosion in the internal combustion engine in an unloaded state is normally accelerated. Then, the time Tn' in which the crank shaft rotates by 30 deg. right after ignition and the time Tn in which the shaft rotates further by 30 deg. are calculated by using an existent crank angle sensor. The difference DELTAT=Tn'-Tn between the both is expected to exceed a constant value and found by experiment. The decrease in the DELTAT is caused by the abnormality in the cylinder. For the purpose, a detection program is incorporated in an engine control CPU to detect the DELTAT and if abnormality occurs, abnormality lamps are turned on by as many as cylinders, so abnormality by cylinders is detected without adding any hardware.

Title: Bleed-off control method using closed center type solenoid proportional directional control valve
Inventor: YAMAJI NORIHEI
IPC: F15B11/00
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To enhance the operability with a simple structure without wasteful energy consumption by controlling a specified number of control valve with a specified arithmetic value on the basis of the manipulated variable of this control valve, the total sum of manipulated variable of all devices, and the flow rate of a hydraulic pump. SOLUTION: The virtual feed flow rate of an i-th control valve 4 to an actuator 1 is calculated from the pump discharge quantity, the manipulated variable of an electric control input device 10 of the control valve 4, and the manipulated variable of all control input devices, and the difference between the feed flow rate and the actuator flow rate is divided by the value obtained by multiplying the bleed-off area suitable to each actuator 1 by the orifice flow rate coefficient followed by squaring to calculate the control valve output pressure command value. The i-th control valve 4 is controlled with an arithmetic value obtained by subtracting the load pressure detected from each actuator 1 from the command value. Accordingly, the bleed-off control can be virtually performed within a CPU, and the actual hydraulic loss can be eliminated to save the energy. Since the device is also simplified by use of a control valve free from a center bypass passage, and no fluid force is generated in control, the operability can be enhanced.
