Abstract: DIRECT WRITING OF REFRACTORY METAL LINES FOR USE          IN INTEGRATED CIRCUIT DEVICES            ABSTRACT OF THE DISCLOSURE          Laser beams are employed for direct writing of micron-sized refractory metal lines at a speed of several centimeters per second on silicon surfaces. Tungsten metal lines are selectfully deposited on silicon surfaces using laser induced chemical vapor deposition.  Smooth tungsten lines with a length of a few centimeters and with a line width of between 2 and 15 microns are obtainable on silicon surfaces by employing argon lasers with focused spot sizes of approximately 20 microns.  The process is particularly useful in the construction of custom integrated circuits, in the placement of discretionary conductors in integrated circuits, in mask correction, and in the correction of defects in large scale integrated circuitry and liquid crystal displays.

Abstract: ABSTRACT          The invention relates to a method of providing the shaving head of a dry-shaving apparatus with an effective shaving area of a desired shape in accordance with its use, in which a shear foil is mounted in an arcuate condition under pretension in a shaving-head frame so as to be movable at the clamping locations.          A cutter is pressed into the curved portion of the shear foil, which cutter also has curved cutting edges, the tangent lines to the clamping curve at the clamping locations extending at an acute angle to each other.  The method is characterized by the steps of: initially clamping the shear foil without the cutter at a pre-selected angle, with a pre-selected length and at a pre-selected distance; subsequently, in addition to the clamping curvature which is not yet influenced by the cutter, a no-load normal-pressure distribution perpendicular to the foil curvature is simulated be-tween the cutter and the foil in conformity with a desired effec-tive shaving area, so that in addition to its curvature depending on this desired form of the normal-pressure distribution the shear foil. experiences in said effective shaving area a simulated deformation relative to the free clamping curvature, the simulated pretension curvature thus obtained corresponds to the desired normal-pressure distribution on the cutter (in the desired effec-tive shaving area) relative to the shear foil.  The cutting edges of the cutter are curved in conformity with the pretension curva-ture of the shear foil thus determined and the cutter, whose shape is in conformity with said pretension curvature, is pressed into the shear foil with the clamping curvature with the force which provides the desired normal-pressure distribution.

Title: Subscriber unit for wireless digital telephone system

IPC: H04B1/40

Granted: 1990-09-25
Abstract: ABSTRACT         A digital wireless subscriber telephone unit for wireless connection with a base station.  The subscriber unit has a baseband processor which is coupled to storage means for the baseband functions.  The baseband processor is direct access  coupled  to  a  modem  processor  whereby  the  two processors may communicate with each other.   The modem processor  generally  acts  as the master  in  the  system, although lock-out means may be used in certain circumstances. The signal from the modem processor is converted to an analog signal, which is subjected to diglitching; and the deglitched signal is then upconverted and filtered to form an IF signal which is thereafter amplified.  The amplified IF signal is combined with a signal generated by a synthesizer to provide an RF signal.  On the basis of certain signals received from the base station, the baseband processor produces initiating signals which determine whether the subscriber unit will be in the transmit mode or the receive mode.   In intervals between actuation of the system, a training mode is used wherein a known signal from the modem processor is compared with looped-back signal to produce correction constants to compensate  for undesirable variations  in the  IF,  these constants being stored for use in correcting actual received signals.  During demodulation, the modulated digital signals are  fed  to  the  modem  processor  in  the  form  of  time multiplexed I and Q samples and are demultiplexed.   The demultiplexed I and Q samples are fed to an equalizer and frequency correction circuit for minimization of errors and for production of a frequency correction signal which is used to correct any errors in the timing of the system and in the output of the synthesizer.

Abstract: The invention concerns a feed wagon for outdoor pigs, which are fed outdoors, i.e., in the paddocks where the pigs are kept. For this, a tractor-pulled feed transport cart is used, being outfitted with a feed magazine 5 and various arrangements 7 to dispense the feed, and designed for transport between the individual paddocks so that the feed can go directly into the paddocks without the pigs escaping. The feed wagon according to the invention has a centrally located, oblong feed magazine which extends along the cart 1 for almost its full length. On either side of the feed magazine there are a number of retractable pig boxes 6, essentially constructed from side partition walls 16, which separate the individual boxes from each other, and back pieces 18 in the boxes. The boxes are dropped down into the horizontal position during feeding, i.e., perpendicular to the wagon on either side of it, and thereby form a number of closed boxes designed individually for the pigs. In each box there is a feed trough 8, which is mounted in connection to the feed magazine 5, i.e., inside the box. By means of a suitable dispensing arrangement 7, which can be common to all feed troughs on the wagon or to the troughs on either side of the wagon, these feed troughs are supplied with feed in measured amount from the magazine during the feeding. During the driving of the feed wagon to and from the paddocks, the boxes 6 are folded up into the vertical transport position, figure 2, so that the boxes do not limit the mobility of the feed wagon or its ability to get through hedge gates, on narrow dirt tracks, etc. A special type of chain drive 19 with common drive arrangement on either side of the wagon is used to retract the boxes. In a special configuration, the boxes can be provided with a fixed bottom 24. The feed wagon can be used, other than for feeding, to move the pigs individually or collectively between different paddocks or between paddocks and the barn. <IMAGE>
