摘要:
A hermetic tubular casing hermetically containing a gas substantially at the atmospheric pressure is mounted on a mobile object, such as a vehicle, and is provided with a needle electrode at one end thereof and a pair of adjacent semicircular plate electrodes at the other end thereof. A high-voltage power supply applies a high voltage across the needle electrode and the plate electrodes to generate an ionic wind flowing from the needle electrode toward the plate electrodes by producing a corona discharge around the needle electrode. An arithmetic unit detects the difference between ionic currents flowing respectively through the pair of plate electrodes and each corresponding to the number of ions fallen on the corresponding plate electrode. The ionic wind is deflected under the action of a Coriolis force as the mobile object revolves entailing variation in the quantity of ions falling on each plate electrode. The difference between the ionic currents varies in proportion to the angular velocity of the mobile object.

An automotive wiper control apparatus has an infrared emitting unit outside an occupant compartment, a photodetector unit inside the compartment in optical alignment with the infrared emitting unit, and an electric control for automatically controlling the wiper operation in dependence on the state in which infrared rays emitted by the infrared emitting unit through a predetermined area of the windshield are received by the photodetector unit. The photodetector unit has an infrared transmission plate formed of an infrared transmissive material and carrying infrared shielding layers applied in a striped pattern to one surface of the plate. The infrared transmission plate is disposed in front of a plurality of photodetectors so that a contrast is produced on the photodetectors by the infrared rays passing through the uncoated zones of the plate which are free from the infrared shielding layers. The contrast is varied with variation in the quantity of raindrops on the predetermined area of the windshield. The electrical control is responsive to the variation in the contrast to automatically control speed of wiper operation as well as intervals of intermittent wiper operations.

A windshield wiper control device for use on a vehicle includes a light-emitting unit mounted on the vehicle outside of a compartment for emitting a ray of infrared radiation, a photodetector unit mounted on the vehicle within the compartment and having a slit plate for producing an image of a striped pattern with bright and dark areas in response to exposure to the ray of electromagnetic radiation through the windshield and an array of photodetectors for sensing the bright and dark areas of the striped image and generating signals indicative of the bright and dark areas, and an arithmetic circuit arrangement for computing a contrast of the bright and dark areas based on the signals from the photodetectors and controlling the speed and/or period of operation of the windshield wiper based on the computed contrast.

A corner or end position indicating apparatus for an automotive vehicle comprises a light source 6 emitting light, and first and second marker point indicators 2 and 3. The first marker point indicator 2, displayed red, is larger and brighter than the second marker point indicator 3 displayed blue. A first optical path is defined between the first marker point indicator 2 and the light source 6, and a second optical path is defined between the second marker point indicator 3 and the light source 6. The first optical path is longer than the second optical path. A concave mirror 5 alters a direction of the light emitted from the light source 5 upward a rear window glass R of the automotive vehicle. The first marker point indicator 2, the light source 6 and the concave mirror 5 are cooperative to form an image 2a of the first marker point indicator 2 at a position corresponding to a corner or end position of a vehicle body. Meanwhile, the second marker point indicator 3, the light source 6 and the concave mirror 5 are cooperative to form an image 3a of the second marker point indicator 3 at a position far from the corner or end position of the vehicle body.

Water-in-oil emulsion explosive compositions containing (e) nitromethane gelatinized product obtained by mixing nitromethane with a gelatinizer for nitromethane and (f) hollow microspheres and/or (g) bubbles formed from a chemical foaming agent in a water-in-oil emulsion composition consisting of (a) ammonium nitrate or ammonium nitrate and the other inorganic oxidizer salts, (b) water, (c) an oil and/or wax and (d) a sorbitan fatty acid ester surfactant.
摘要:
A heads-up display unit provided with a display device serving as display image forming means which displays a display image. A hologram serves as a reflecting means, and reflects the display light emitted from the display device, causing reflection of the display image on the interior surface of a vehicle's windshield. A display image is formed outside the windshield towards the front of the vehicle. A concave mirror having a different focal length in different directions is recorded in the hologram serving as a reflecting means so as to offset distortion of the display image caused by curvatures of the windshield. This construction makes it possible to cause the windshield to display a display image free from distortion.

A cooling device for cooling an electronic component (semiconductor module) includes a cooling tube adapted to be disposed in contact with the electronic component and having an internal coolant flow channel for the passage therethrough of a cooling medium, and a high-pressure tube disposed adjacent to a surface of the cooling tube that faces away from the electronic component, the high-pressure tube having a hollow interior that can be filled with a high-pressure fluid having a pressure higher than that of the cooling medium. An electric power conversion device comprised of a plurality of semiconductor modules and the cooling device as means for cooling the semiconductor modules is also disclosed.
摘要:
A vehicular extreme position display system displays a stereoscopic image of a three-dimensional object near a vehicular extreme position. The system provides different levels in brightness on the displayed stereoscopic image to enhance the stereoscopic effect. The displayed stereoscopic image may be arranged to change in color and brightness depending on monitored background illuminance. Further, the display of the stereoscopic image may be arranged to automatically terminate when a preset condition is matched.

A water-in-oil emulsion explosive, comprising aqueous inorganic oxidizer solution, oil, emulsifier and hollow microspheres, and having high low-temperature detonability and storage stability can be produced without causing breakage of the hollow microspheres through a specifically limited kneading method, wherein agitating blades fitted to an agitating shaft in a kneader are subjected to up and down movements in the axial directions of the agitating shaft and concurrently to a rotary motion to knead homogeneously a water-in-oil emulsion formed of the aqueous solution of inorganic oxidizer, oil and emulsifier, together with the hollow microspheres.
