Title: Car lighting system and method for control thereof
Inventor: ANTE YOSHITSUKU
IPC: F21S8/10
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To surely and optimally illuminate a road ahead of a vehicle by automatically controlling adjustment means so that a minimum beam range does not drop below the actual stopping distance of the vehicle. SOLUTION: A control means 60 continuously receives speed data Dv from a speed sensor 40 and receives data De indicating an actual steering angle from a steering angle detector 30. Road condition data Ds and weather information Dw input to an input means 80 by a driver are input to the control means 60, together with fixed preset data Df about the characteristics of the vehicle such as the kind of the vehicle and tires. The control means 60 determines the settings of the reflector of a headlamp unit and a lamp unit 70 at optimum values according to these data. The road ahead of the vehicle is surely and optimally illuminated by automatic control such that a minimum beam range does not drop below the actual stopping distance of the vehicle.

Abstract: PURPOSE:To enable to dissolve a large amt. of gas in a drink by communicating a freely openable and closeable passage for a drink and the inside of a vessel to a housing section of a gas cylinder with a valve and providing a gas passage having a smaller sectional part at the narrowest part of the passage than the sectional area of the narrowest section of the drink passage. CONSTITUTION:When a drink L is charged to a vessel 1 and a body 46 housing a cylinder 55 is fitted by screw clamping to a cover body 41, the cylinder 55 is opened by a needle 44, and gaseous CO2 in the cylinder is ejected into the drink L through a small dia. part 42 and the gas passage 32. Since the sectional area of the gas passage 32 at the narrowest section is smaller than the sectional area of the narrowest section of the drink passage 29, the amt. of ejected gas per unit time is less, so the gas is ejected for a long time and dissolves in a large amt. in the drink L. Then, when a handle 27 is pushed down, a valve 26 is pulled up against the force of a spring 28, so the passage for the drink 29 is opened and the drink L pushed down by the gas in an accumulator 5 for gas for pushing down the drink L is discharged to the outside through a passage 29.

Title: Pressure leak inspecting tool for box body for vehicle
Inventor: FUJITA TETSUJI
IPC: G01M3/02
Filed: 1989-09-01
Abstract: PURPOSE:To prevent the inspecting tool from malfunctioning and to enable high-accuracy unmanned inspection by forming a low-reflection surface on the opposite wall surface from an inspection hole. CONSTITUTION:A camera 4 for inspection and an illumination lamp are moved to in front of the inspection hole if to project intense light on the inside. If there is a defect which spoils airtightness such as a crack or welding defect in a body 3 to be inspected, an air bubble is produced and grown at the part to leave the body 3 to be inspected and float to the surface of water. The camera 4 photographs the body 3 to be inspected. Then when the air bubble is produced and grown on the surface of the body 3 to be inspected, that is displayed on a display, but when there is no defect, nothing is displayed. Part of the light projected on the inside which does not strike the body 3 to be inspected is absorbed by the low-reflection surface (plate material 1h) provided on the opposite wall surface from the inspection hole if and unnecessary irregular reflection is precluded, so that a sharp image is picked up by the camera 4. Consequently, the inspecting tool is prevented from malfunctioning and high- accuracy unmanned inspection becomes possible.
