Abstract: A fan motor is mounted on the upper wall of the casing. The lower surface of this upper wall is formed into an inclined surface in which inclination is formed from the front wall side of the casing toward a back wall across from the front wall. When the fan motor is driven, oil mist or moisture contained in the air are condensed into water droplets or oil droplets. These water droplets or oil droplets fall and flow to the inner wall surface of the upper wall of the casing along the inner peripheral wall of a vent hole. Then the water droplets or oil droplets flow along the profile line of a vent hole smoothly (without stopping) and roll down the side wall of the casing.

Abstract: In an environment monitoring system using an optical flow, a monitoring region is set in one's own vehicle lane or an adjacent lane on the basis of the white lines. In this case, an early image is divided into a plurality of small regions. An edge is extracted which is an candidate of each the white lines for each the small regions using a virtual FOE for each the small regions acquired previously of the early image. A white line is determined is determined on the basis of the edge extracted. Finally, white line segments are extended for each small region determined to acquire a coordinate of a crossing point thereof and that of the virtual FOE is stored for each the small regions. The virtual FOE is used to extract the edge for each of the small regions of an image newly picked-up in order to detect the optical flow.

Abstract: The vehicle surroundings monitor detects the sizes and positions of obstacles, ditches and humans as well as the depths of the ditches to provide the driver with sufficient information to secure safety during driving. The pattern light projector receives an incoming laser beam and projects a light spot matrix in the form of a regular grating onto the monitored area. The camera photographs the light spot pattern on the monitored area and sends image signals to the data processor which processes the image signals to detect the presence of any obstacle, ditch or human. Based on the steering angle detected by the steering angle sensor, the path the car will take is predicted and a possible contact or collision of the car with the obstacle is detected beforehand. The buzzer, voice synthesizer and display device are used to alert the driver and indicate the presence of the obstacles, the possible contact with them and the location where the possible contact will occur.

The collision alarm method and apparatus for vehicles detect danger of collision at high speed and gives a timely alarm so as to enable collision avoiding action to be securely taken.

Abstract: A casing structure for a numerical control unit in which a cooling fan mounted on a fan cover is electrically connected with a control board attached to a main cover without using cables. A terminal unit connected with wiring of a fan motor is fixed to a fan cover, and a power supply terminal to be directly connected with the terminal unit is fixed to an upper end portion of a main control board The terminal unit is connected with or disconnected from the power supply terminal by attaching or detaching the fan cover to or from a casing body. Since cables are not needed for connection, a casing can be assembled and disassembled easily. Further, since an assembling error due to interference of cables is eliminated, automation of the assembling work can be easily achieved.

Abstract: In a driver monitoring system, a pattern projecting device consisting of two fiber gratings stacked orthogonally which receive light from a light source projects a pattern of bright spots on a face of a driver. A image pick-up device picks up the pattern of bright spots to provide an image of the face. A data processing device processes the image, samples the driver's face to acquire three-dimensional position data at sampling points and processing the data thus acquired to provide inclinations of the face of the driver in vertical, horizontal and oblique directions. A decision device decides whether or not the driver is in a dangerous state in accordance with the inclinations of the face obtained. A warning device warns the driver against his dangerous state. The pattern light projecting device and pick-up device are integrated to each other and installed on a steering column on a vehicle.

Abstract: A liquid tank includes a tank body forming a reservoir for gasoline G, a flexible partition film 1 arranged in the tank body 1 to divide a space in the tank body into two vertical spaces, a float positioned on the gasoline G, an arm 3 for converting a high and low position of the float 3 into a rotational position of the arm 5, and a potentiometer 5 for detecting a position of the flexible partition film. Since the gasoline G is covered with the partition film, the gasoline G does not vaporize into the air in the tank body an. Even if the gasoline surface is slanted to the tank body an by an acceleration of the vehicle, the flexible partition film serves to restrict the inclination of the surface. Therefore, it is possible to precisely a residual amounts of the gasoline G irrespective of the inclination.

Abstract: In a remaining fuel amount measuring apparatus for a fuel tank which is suited to the fuel tank designed to suppress generation of fuel vapor, a CPU actuates a piston to supply a prescribed amount of air into a pressure adjusting chamber, thereby increasing the pressure within the pressure adjusting chamber. From the Boyle's law, the increasing rate of air before air supply is inversely proportional to the volume V of the pressure adjusting chamber. Therefore, the CPU, referring to the pressure within the pressure adjusting chamber before and after the air supply, acquires the volume V of the pressure adjusting chamber, and subtracts the volume V of the pressure adjusting chamber from the internal volume of a tank body to acquire the volume of a fuel chamber, i.e. remaining fuel amount.
