Abstract: An optical disk (2) reproducing apparatus having a brake device for emitting a brake signal includes a track jump control device (37) adapted to inhibit, during a track jump operation, the operation of the brake device until a predetermined period has elapsed starting from a time not earlier than the termination of the emission of the brake signal. Thus, the brake device does not operate until the emission of the brake signal has been terminated, so that, if there is some defect in the target track to which the pickup (4) is to be jumped, the brake device does not malfunction. Accordingly, the drive device can reliably effect a track jump even if the target track of the track jump has some defect. Further, the brake device operates after the above-mentioned predetermined period has elapsed, so that, if a track stray happens to occur due to some defect in the target track, the effect of such a defect can be reduced.

IPC: H01L21/68
Filed: 1991-07-10
Abstract: A method for increasing accuracy and reducing the time required to teach the target bonding points on a reference semiconductor device and its associated lead frame comprise manually approximately locating at least a first target bonding point and at each approximately located bonding point causing the pattern recognition system (PRS) of an automatic wire bonder to relocate the exact center of preferred target bonding point automatically. The direction and approximate distance to the next bonding point is programmed into the PRS to enable the PRS to automatically step to the next approximate location of a next bonding point or a pad or a lead. At each pad or lead the PRS is programmed to find or relocate this bonding point at the exact center or preferred target bonding point on the lead or pad. It is possible to program such automatic teach operations on pads or leads over a complete semiconductor or preferably over a plurality of pads or leads arranged in continuing direction and spaced from each other by a predetermined pitch. During bonding of production semiconductor devices the taught bonding points are employed as approximate bonding points which causes the PRS to again relocate the exact preferred target bonding points with reference to the PRS located edges of the pads and leads to be bonded.

Abstract: The screw-thread neck of a container, e.g. a glass bottle, has a closure with a tamper-evident ring 32 connected to the lower end of the skirt of the closure by frangible bridges 31. Opposite the ring, the neck finish of the container has a nose-shaped projection 14 the upper and lower flanks of which meet in a sharp edge, and has an annular groove 18 below the projection 14. The bridges 31 are formed in an inwardly facing groove 30 above the projection 14 and are radially spaced from the outer surface of the neck finish. The tamper-evident ring is swaged into close contact with the projection 14, is deformed into a channel 19 on the neck finish below projection 14, and is closely engaged with the surface 21 of the neck finish below the channel. Interference involving outward prising movement by a lever on the lower edge portion 34 of the ring to disengage the ring from groove 18 causes a pivoting action about the tip of projection 14 leading to fracture of the bridges.

Title: Shelving system
Inventor: JACOBS KENNETH
IPC: A47B96/06
Filed: 1991-11-21
Abstract: A modular shelving system has a vertical stanchion for supporting load-bearing blocks (23). One end of each block fits into a T-shaped channel of the stanchion. A self-tapping screw threaded into the block engages the back wall of the channel and forces the block against the shoulders at the mouth of the channel. A pointed tip on the screw pierces the back wall of the channel to keep the block from moving along the channel. Shelf brackets (24) of generally U-shaped cross section may be attached to the blocks and rear wall of a closet and support either end of a shelf plank (32) in the channel formed by the U-shape. Shelf brackets may also be attached to the side walls of the closet. A curved washer (33) fits between the U-shaped shelf bracket and a stanchion or closet wall for alignment. Since the ends of the shelf plank are concealed in the U-shaped brackets, unfinished ends and poorly aligned ends on the shelf plank are acceptable. Shelf planks may be formed from a plurality of interlocking metal shelf slats. Blocks may also be used to support drawer runners, hanger bars or other accessories.

Abstract: 1. Partially crystalline transition aluminium oxides, process for their preparation and use thereof for the production of mouldings essentially comprising gamma-Al2O3. 2.1 The decomposition products obtained by the known processes still contain crystalline fractions of undecomposed aluminium trihydroxide, especially of hydrargillite and/or fractions of hydrothermally produced boehmite, and as a result the required solid state reactivity is not always achieved. 2.2 The object is to produce partially crystalline transition aluminium oxides, which have a uniform phase composition and a high solid state reactivity, and which in the rehydration process even at atmospheric pressure make it possible to achieve a high degree of conversion of the solids particles into a finely fibrous boehmite, so as to ensure efficient further processing to give mouldings, which essentially comprise gamma-Al2O3 and which have a well developed internal surface and high mechanical stability. The partially crystalline transition aluminium oxide is characterised in that the solid, in addition to aluminium having coordination numbers of 4 and 6 also comprises aluminium with a coordination number of 5 vis-à-vis oxygen, the proportion of aluminium with a coordination number of 5 comprising at least 50% of the content of aluminium with a coordination number of 4. 2.3 The Al2O3 mouldings produced by the process according to the invention are suitable for the use as adsorbents, gas purification compositions, catalyst components or catalyst supports.

Abstract: The invention relates to a yarn tensile strength sensor, in particular for rapidly moving yarns. The object is precisely to determine even short-period fluctuations in yarn tensile strength. According to the invention, this object is achieved when a yarn-guiding element (6) is mounted on a head end of a plunger-type coil (5) arranged in a magnetic field. Arranged in the region of the plunger-type coil (5) is a position sensor (12) which detects even minimal changes in the position of the plunger-type coil (5). These changes in position are signalled to a controller (14) at the output of which such changes in current are produced and fed to the winding of the plunger-type coil (5) so that the axial force produced by the yarn (11) and acting on the plunger-type coil (5) is compensated. The plunger-type coil (5) is thus virtually free of movement.
