Abstract: Lateral release front jaws of a safety ski binding for holding the front end of a ski boot have a trunnion (30) attached to the ski, a release spring (13) arranged essentially in the longitudinal direction of the ski and a sole holder (29) which has two side legs (14) and a holding-down device (15) for the sole. The one-piece sole holder (29) is arranged rotatably on the trunnion (30) and vertically tiltably about a transverse axis (36). A slide bore (37') in a ball guide (37) inside the trunnion (30) is passed through by a connecting rod (38) which bears via a support disk (39), which is fastened to it at the rear, against an essentially plane rear support surface (40) of the trunnion (30). The rear end of the release spring (13) rests on a stop abutment (42) attached to the sole holder so that this stop abutment is pressed against the front support surface (31) of the trunnion (30). The rear support surface (40') of the trunnion (30) or the opposing surface (39') of the support disk (39) above the connecting rod (38) or the support surface (31') of the trunnion (30) or the opposing surface (42') of the abutment (42) below the connecting rod (38) are tilted, in relation to the vertical, on the surface of the ski (22) in such a manner that, within a predetermined height-tilting range (a) of the holding-down device (15), the holding-down force is clearly reduced in relation to the normal release holding-down force.

Abstract: For the fuse of a spinning projectile, a space-saving safety device 1 provides a radially expandable holding ring 2, which in the safety position of the rotor 5 centres the latter within a fuse housing 7. The holding ring 2 is held on the rotor 5 in the axial direction by means of a compression spring 3. Under the envisaged launching acceleration and spin, the forces of inertia cause the holding ring 2 first of all to be set back axially and then to be forced radially into a radial groove 30, where it remains. This deactivates the safety mechanism of the rotor 5, which swivels into a primed position.

IPC: C08F287/00
Filed: 1989-06-27
Abstract: A process for incorporating carboxyl and/or carboxyl derivative functionality into a hydrocarbon polymer which is substantially free of ethylenic unsaturation. The functionalization is accomplished by contacting the functionalizing agent or agents with the polymer in the presence of a free radical initiator in a blending apparatus capable of imparting high mechanical energy into the reaction medium. The blending apparatus is preferably an extruder and most preferably a non-intermeshing twin screw extruder. The amount of degradation resulting from the presence of a free radical initiator and the high mechanical shear at the elevated temperatures employed during the contact­ing is reduced by effecting the contacting in a suit­able diluent. Similarly, the amount of polymer cross­linking and/or coupling is reduced through the use of a suitable diluent. The polymer is maintained in the molten phase during the reaction.

Abstract: A wafer chuck (2) usable with a semiconductor exposure apparatus (Fig.2A) wherein a mask and a semiconductor wafer (1) are placed in a vacuum ambience or a pressure-reduced gas ambience, and wherein the wafer (1) is exposed through the mask to radiation energy such as X-rays contained in a synchrotron radiation beam, by which the pattern of the mask is transferred onto the wafer (1). The wafer (1) is first attracted on the wafer supporting surface of the chuck (2) by vacuum attraction (21), and thereafter, the wafer (1) is attracted by electrostatic attraction force. Thereafter, the vacuum attraction is broken by supplying (24) a gas. Preferably Helium or other thermally conductive gas is admitted at this point. When the pattern of the mask is transferred onto the wafer (1), the wafer (1) is retained on the wafer supporting surface (20) by the electrostatic attraction force only. By this, the wafer supporting apparatus can correctly contact the wafer supporting surface (20) to the wafer (1) without being influenced by the undulation of the wafer (1). In addition, the heat produced in the wafer (1) during exposure can be removed efficiently by temperature controlled (23) water (11) supplied to the wafer supporting apparatus (2).

Title: Substance vaporizing apparatus
Inventor: TABATA YOICHIRO C O MITSUBISHI
IPC: H01S3/03
Filed: 1990-06-12
Abstract: A substance vaporizing apparatus which uses a vapor (5) of a sub­stance generated by heating the substance in a gas-filled tube (2) as an exciting medium or an ionizing medium. The apparatus employs an im­proved container (22, 222, 224, 225) for containing the substance within the gas-filled tube (2). The improved container (22, 222, 224, 225) suppresses the rate of emission of the vapor (5) of the substance into a discharge space (3) defined by the gas-filled tube (2) to hold the vapor (5) density of the substance at an optimum low value for laser oscillation relative to the buffer gas density in the discharge space (3). Thus, the mean free path of the atoms of the substance, namely the average distance traveled by the atoms between elastic collisions with the electrons, ions and neutral atoms of the buffer gas, is increased to increase the number of atoms of the substance excited to a higher energy level, which, consequently, increases laser power and enhances laser beam or ion beam accelerating energy. The employment of segmental discharge electrodes (1a, 1b) each consisting of a plurality of partial electrodes diametrically distributed in the discharge space of the gas-filled tube (2) enables heating the buffer gas in a substantially uniform diametrical temperature distribution, which enables to increase the length and diameter of the laser medium. The employment of two pulse generating circuits (200, 300) promotes the relaxation of the atoms of the substance from a lower energy level to the ground energy level to enable the next application of a pulse voltage to establish a complete popula­tion inversion, which enables the substance vaporizing apparatus to operate at a high efficiency at a high discharge frequency.

Abstract: A device for loading a cargo hold (3) in a fuselage (1) of an aircraft with packages is proposed which permits a carpet-like transport surface (18) to be used for transporting the cargo into the depth of the cargo hold (3) and out of it again by means of a motor drive. A sliding plate (143) is supported suspended at a distance over the floor-side support structure (145) of the cargo hold (3) laterally by means of springs (148) in such a way that the gap from the floor- side support structure (145) is maintained even when there is a maximum nominal load on the floor (14) of the cargo hold (3). In this way, it is ensured that frictional forces occur when there is movement of the transport surface (18) merely between its underside and the low-friction surface of the sliding plate (143), whilst longitudinal sections of the transport element (18) guided back on the underside can be moved completely free of force in the gap. Overloading of the sliding plate (143) or of its support by means of centrifugal forces which may occur during flight can be ruled out in that, with the closing of the gap, the sliding plate (143) comes to rest against supporting bearings of the floor-side support structure (145). A restraining structure for the lateral upper edges of the transport surface (18) constructed with a trough-shaped cross-section prevents the formation of folds. <IMAGE>
