Abstract: The invention relates to a front jaw (1) with a housing (2), with a release spring (5) and with a tie rod (8) which can be actuated against the force of this spring and on which a control plate (9) is arranged which is subjected to the action of shorter lever arms (11a) of two angle levers (11) mounted on vertical axles in the housing. The object of the invention is to compensate for the increased release force in the event of a forward or backward fall during turning. According to the invention, control members (20) which have limited freedom of movement are arranged on the angle levers and each bear, with their three mutually adjacent sections, on three support surfaces. One support surface is formed by the control plate, the second by the vertical axle (10) and the third by a control surface (19a) of a control body. This control body is arranged on one of the lever arms of a double-armed pedal (12) whose other lever arm lies below the ball of the foot and, in the movement position (position of rest), is located at a distance from the upper side of the ski. When the pedal is subjected to load, the control body is pivoted upwards and changes the position of the two control members on their control surfaces. <IMAGE>

Abstract: The invention relates to a method for allocating a resource in a periodic frame of a satellite asynchronous digital network, on each of the bursts of cells of the sporadic connections transmitted by land stations. A request for resource allocation, such as a time interval in a data sub-frame of the frame, is transmitted by the land station to a central station for network management, from the start of reception of the burst and thus well before the land station has fully received the burst coming from one of the user stations. Each of the resource allocation requests relating to the bursts of a connection is satisfied since the request includes no information about the burst. The acceptance or refusal of a request for connection is determined as a function of an algorithm precluding any overloading of the network and a slump in its performance. <IMAGE>

Abstract: A device for placing seed into the soil at a specific pitch in which radiating spikes of two star wheel formed discs (6,7) are brought together by rotating the discs (6,7) synchronously at an angle and that each of the radiating spikes has on its inner side a hollow channel forming an internal closed funnel (3) when the spikes are brought together and opens when by further rotating the spikes move away from each other. The means to place seed or small objects into the funnels (3) consists of a hub (2) disposed about the axis of rotation of the discs (6,7) and mounted to rotate with the discs (6,7), which hub (2) is provided with cells adapted to receive the seed or the other small objects and to release them upon rotation of the discs (6,7) so they can fall under gravity into the funnel (3). 
     The device is particularly suitable to plant seed into soil covered by a thick crop residue.

Abstract: In an SOR exposure system for transferring patterns on masks to semiconductor wafers by using SOR light (4) reflected by an X-ray reflecting mirror (9A,9B), a first shutter device (5A,5B) for shielding at least γ rays and a second shutter device (8A,8B) for shielding X-rays are provided between the SOR ring and the mirror inside a beam port, and an exposure adjustment device (11A,11B) for adjusting the amount of exposure when a circuit pattern on a mask (12A,12B) is transferred to a wafer (13A,13B) is provided between the mirror and the wafer. As a result, the human body can be protected against radiation rays, such as gamma rays, generated from the SOR ring when electrons are injected or when the SOR ring is stopped. Damage to the X-ray reflecting mirror caused by radiation rays is reduced, and stable reflectance of the mirror can be obtained. Maintenance of the SOR exposure system is also made easier.

Abstract: A belt tightener with a pyrotechnic piston-cylinder drive has a vehicle-sensitive weight which is formed by a pivotably mounted casing block (14), a gas generator (18) inserted into the latter and a piston-cylinder unit (20). In order to ensure that the casing block (14) is freely pivotable, the piston (24) is accommodated in the cylinder (22) with axial and radial play. The piston (24) is provided with an annular groove (50) in which there is arranged an annular seal (52). When not subjected to the pressure of the gas, the annular seal (52) is not in contact with the inside wall of the cylinder (22). The pressure of the gas causes the annular seal (52) to move axially along the conically rising bottom (56) of the annular groove (50) and expand radially at the same time, until it engages with the inside wall of the cylinder (22) in a sealing manner. …<IMAGE>…

Abstract: Disclosed is a method for specular polishing the surface of a metal or non-metal plate (10) to be polished, especially a large-sized plate, in which the surface of the plate is polished by rotating a polishing member (9) via cranks (36, 37), while pressing the polishing member against the surface of the plate at a predetermined pressure. Since the polishing member is rotated via cranks, while being pressed against the surface of the plate at a predetermined pressure, the predetermined pressure is uniformly distributed over the entire surface to be polished, hence, precise and uniform specular polishing of even a large-sized plate is feasible.

Abstract: A transflective liquid crystal display (LCD) uses the reflective and refractive characteristics of an edge-lit flat light pipe as a backlight panel (36) behind the liquid crystal layer. The front and/or back surfaces (44, 46) of the backlight panel (36) are textured to enhance reflectivity of ambient light and transmission of edge light. The front surface (44) of the panel is textured with pits (48) that have walls at an angle to enhance reflectivity over a range of viewing angles. The back surface (46) of the panel is textured with pits (50) having wall angles and a pattern to enhance the uniform reflection of edge light toward and through the front surface (44) of the backlight panel (36). The indentations may be conical, triangular or random. The pit wall angles lie within a preferred range of angles to optimize the amount of light within the useable viewing angle for the LCD.
