The invention concerns a device for positioning and stopping the leg-rest section (18) with adjustable inclination of a sun bed, which includes stop means (19) applied underneath leg-rest section, and guide means (20) applied to each bearing foot (14) of the bed and interacting with said stop means so as to stop the leg-rest section in several inclinations.

Upper and lower shell members of aluminum-plated steel panels have respective flanges overlapping each other and welded to each other by a laser beam, forming a fuel tank. One of the flanges has a stepped region spaced from the other of the flanges, defining a gap between the stepped region and the other flange. The laser beam is applied to the flanges closely to the gap for discharging unwanted c...

Land vehicle navigation apparatus (10) includes computer (11) for calculating first and second navigation routes (1, 2, or 3) between start (72) and destination (73) locations. Both routes are preferably visible to vehicle operator at same time along with route criteria such as route travel mileage and/or route estimated travel time. Vehicle operator selects which displayed route is used for provi...

A method and an apparatus for specifying slice planes in an X-ray CT, capable of specifying a slice plane corresponding to the desired tomographic image easily and accurately. In the apparatus, scans of the body to be examined are carried out and the projection data are stored in the large capacity memory (11) first. Then, a scanogram of the body to be examined is displayed, on which a cursor (21,...

The machine has a supporting cutter bar (12) and a counter cutter (11) detachably fitted thereon. The cutter bar and counter cutter are attached together with the cutter holder (19) on the top side to a swing bar (20) on each end by a connecting support tube (21). This support tube is mounted with eccentricity on a continuous shaft (22) in order to set accurately the cutter gap (SP) over the entir...

The controller has a control unit which reduces the torque input into a transmission (18) during its speed change operation. The transmission is arranged between a motor generator (14), driving wheel and an engine (12) to change the gear ratio. The engine is operated by the combustion of fuel. The control unit has first and second down parts which use engine and motor generator as torque down sour...

A grinder of solids or solids in liquids has a multiple milling stage. A rotating disc plate (22) carries cutting elements (28) on one side and hammer elements (30) on another, both located at the circumference of the disc plate. The disc plate (22) is rotated in a screened chamber (16) to which the solids or the liquids containing solids to be ground are introduced. Ground product or slurry conta...

A polyester film has an opaque first layer having an optical density greater than 2.0, and a white second layer. The opaque first layer preferably contains carbon black. The film is particularly suitable for use as a base for a photographic sheet.; L'invention concerne un film de polyester. Ce film comporte une première couche opaque dont la densité optique est supérieure à 2,0 et une deuxième cou...

Es handelt sich um eine Watchdog-Schaltung für einen Mikroprozessor, welcher einen Reseteingang und einen Steuerausgang hat, welch letzterer bei normaler Funktion programmgesteuert periodisch ein Signal (P0B2) vorgegebener Zeitdauer (t2) abgibt, mit einem über einen Ladekreis aufladbaren Kondensator (32), mit einem vom Steuerausgang gesteuerten Entladekreis (40, 42) für diesen Kondensator (32) zum...

A posted-write queuing program for writing information sectors to disk sectors includes error-handling routines to minimize the risk of data loss upon specified types of errors. Upon timeouts, queuing is suspended and all information sectors pending in the queue are written out to the corresponding disk sectors. Upon specified types of write errors, queuing is discontinued and repeated attempts ar...

An inspection method and apparatus is disclosed, wherein a laser beam from a laser source is separated into two orthogonal, linearly polarized lights which are then modulated at different shift frequencies and are projected on the same spot on a surface to be inspected. Scattered light resulting in response to impingement of one laser beam and resulting from depolarization attributable to a partic...

A fuzzy logic based navigation module for use on a semi-autonomous vehicle computes the safety of moving from predefined local regions to adjacent local regions for the purpose of planning a safe path for the vehicle to take to reach its intended destination. Image understanding software provides the input to the system in the form of values for linguistic variables for each local region which imp...

A surface-emitting laser system includes a laser (2) that emits a vertically divergent beam (20) generally parallel to the substrate (4) on which it is formed, and a turning mirror (18') in the path of the beam (20) that extends up from the substrate (4) to a level well above the laser height. The extended mirror area (24) reflects a greater portion of the beam (20) than prior planar designs, incr...

In a method for inspecting a dished end face of a nuclear fuel pellet (P), a focused beam of light is emitted to a dish (PA) of the end face of the nuclear fuel pellet while a parallel beam of light is being emitted to the end face thereof. An image of the end face of the nuclear fuel pellet is picked up and the quality of the pellet is judged based on the picked-up image. An apparatus for inspect...

A hand-held, battery operated, single photon sensitivity phytoluminometer with light intensifiers (G) and (H) is claimed for rapid, simple nondestructive, noninvasive evaluation of photosynthetic topography in green leaves. All the steps for generating phytoluminescence are performed within a single, light tight enclosure (X). The sensitivity of the instrument is such that stress induced changes i...

Foamed polyvinyl alcohol can be produced by extruding in the presence of water which acts as a blowing agent. The material is rendered waterproof by incorporating in the surface a UV-curable resin.
