Title: Control method of fuel supply for internal combustion engine
Inventor: MIZUMORI TAKASHI
IPC: F02D45/00
Filed: 1990-11-28
Abstract: PURPOSE:To control an air-fuel ratio so as to become the specified one at all times by compensating the measured error of an intake air quantity through the generated torque value of an internal combustion engine. CONSTITUTION:An intake air quantity is measured by an air flow sensor 2, and an amount of fuel conformed to the measured value is sprayed out of an injector 6. Here, turning angle acceleration per rotation 18 of a crankshaft od calculated by a signal out of a crank angle 9 attached to this crankshaft 18. Then, output torque in the crankshaft 18 is calculated from engine speed moment and running torque found out of this turning angle acceleration. With this constitution, a true intake air quantity can be calculated back, so that it is compensable to a fuel injection quantity in response to the true intake air quantity at a fuel injection quantity compensation arithmetic unit 11. Accordingly, a measured error of the air flow sensor 2 is compensated, througfh which engine driving at the specifiec air-fuel ratio is made achievable at all times.

Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To attain the reduction of an installation cost without necessitating exclusive equipment by transferring data through a telephone line network to a second reception facility which is installed at a monitoring center separated away from a first reception facility and receiving these data through an ordinary computer. SOLUTION: Signals are fetched and displayed through a telephone line network 3 by a first reception facility 20A while connecting terminal equipment 1A and 1B with a monitoring object facility/a burglar prevention/disaster prevention center. A person in charge of a monitor at that facility performs scheduled processing according to the display. Then, when the contents or time are matched with the preset conditions of the terminal equipment to be reported, the first reception facility 20A transfers the report to a second reception facility 20B installed at a monitoring center B separated away from the first reception facility 20A and displays it while converting the report into a prescribed word matching with the transfer destination. The monitoring person watches that report and performs processing corresponding to the contents.  In this case, the second reception facility 20B for receiving a transfer message from the first reception facility 20A uses a personal computer to be ordinarily used. Then, this personal computer is used for any purpose excepting for a monitoring job as well.

Title: Front lighting device for vehicle
Inventor: HAYASHI NORIO
IPC: F21V13/00
Filed: 1988-12-28
Abstract: PURPOSE:To improve the visibility which makes it easier to confirm direction of turning when a car is banked excessively by arranging many small holes or notches in the upper portion of a shielding plate of a projector-type front light in a direction of width. CONSTITUTION:Small holes 5 are arranged in the upper portion of a shielding plate 4 in a direction of width. Notches or a combination of holes and notches may be used instead of holes 5. The light from an electric lamp 2 is reflected by a reflecting mirror 1, passes through a second focus f2, and is then turned into parallel rays of light by a lens 3. The light below the focus f2 is cut off by the shielding plate 4, but the light leaking from the holes 5 dimly illuminates a non-illumination portion which is an upper half with reference to an optical axis L. This dim illumination is adjusted by the number, size and pitch of the holes 5. This arrangement makes it easier to confirm direction of turning through positive illumination when a car is banked excessively for turning. Additionally, dim illumination is directed diagonally upwards, ensuring improved visibility even when car-height is low.
