The present invention is directed particularly to an improved method usingowder metallurgy for the manufacture of the grooved cooling wall of a liquid-propellant rocket combustion chamber. The surface of an inner cylinder constituting the cooling wall is formed with cooling grooves, and these grooves are densely filled up with a filler such as paraffin wax. Thereafter, metal powder which will provide an outer cylinder is compression-molded to a predetermined thickness around the inner cylinder. This metal powder is the same material as the material of the inner cylinder. After the paraffin wax which is the filler is evaporated and removed, the compression-molded metal powder body is sintered in a furnace. During this sintering heat treatment, the inner and outer cylinders are rigidly joined together by the sintering reaction between the atoms of the inner cylinder and the atoms of the metal powder.

An external environment recognition device for a vehicle and a vehicle system capable of assuring safety and reducing the processing load in a compatible manner are provided. An external environment recognition device 100 for a vehicle includes: first collision determination means 103 for computing a risk of collision of a host vehicle with a detected object in front of the host vehicle on the basis of information of a predicted course of the host vehicle and the detected object; and second collision determination means 104 for determining whether the detected object enters the predicted course from the outside of the predicted course or not. This device further includes object selection means 105 for selecting the detected object having a risk at least a first threshold and the detected object determined to enter the predicted course as selection candidate objects from among the detected objects, and for selecting the selection candidate object having a minimum relative distance to the host vehicle as a pedestrian determination request object from among the selected selection candidate objects. This device further includes pedestrian determination means 106 for determining whether the selected pedestrian determination request object is a pedestrian or not using image information.

A side airbag device incorporates an airbag which is fixed to and held by a vehicle so as to be folded in roll form, from a front portion to a rear portion of the vehicle, and which is expanded and developed like a curtain parallel with the inner surface of the side wall of the vehicle by a gas of an inflator when a collision is detected. An airbag support belt is attached to a portion, in close proximity to a top edge of the airbag and close to an attachment position of the inflator, of the airbag. The airbag support belt is wound around the circumferential surface of the inflator and a tip locking hole of the airbag support belt is fixed to a locking projection provided on the inflator, whereby the inflator is integrated with a part of the airbag which is folded in roll form.

The present invention provides an obstacle detection device that enables stable obstacle detection with less misdetections even when a bright section and a dark section are present in an obstacle and a continuous contour of the obstacle is present across the bright section and the dark section. The obstacle detection device includes a processed image generating unit that generates a processed image for detecting an obstacle from a picked-up image, a small region dividing unit that divides the processed image into plural small regions, an edge threshold setting unit that sets an edge threshold for each of the small regions from pixel values of the plural small regions and the processed image, an edge extracting unit that calculates a gray gradient value of each of the small regions from the plural small regions and the processed image and generates, using the edge threshold for the small region corresponding to the calculated gray gradient value, an edge image and a gradient direction image, and an obstacle recognizing unit that determines presence or absence of an obstacle from the edge image in a matching determination region set in the edge image and the gradient direction image corresponding to the edge image. The small region dividing unit divides the processed image into the plural small regions on the basis of an illumination state on the outside of the own vehicle.

A map display device and a map display method, in which a building in a map is formed as a pseudo three-dimensional figure and arithmetic processing to display the figure as a bird's-eye view is simplified. The map display device 20 for displaying map data, formed from vector data, on a display means has a plane figure-for-bird's-eye-view creation means 218, a shift amount storage means 219, a building position determination means 220, and a figure data copying means 221. The plane-figure-for-bird's-eye-view creation means 218 creates, from the map data formed from vector data, a plane figure for creating a bird's-eye view. The figure data copying means 221 copies and draws the plane figure to display a bird's-eye view. This is performed based on the positions of buildings determined by the building determination means 220 and on the shift amounts stored in the shift amount storage means 219, and in this process, the plane figures are shifted upward on a display screen according to the shift amounts, and the copying and drawing are made one by one from a building positioned on the far side in the bird's-eye view.
