Filed: 1988-10-25
Abstract: A plasma processing apparatus and process endpoint detection method comprising a plasma chamber for processing an item that has a first portion of a first material and a second portion of a second material, with the first and second materials having different work functions, and means for generating a plasma in the plasma chamber, with the plasma generating means including at least a pair of RF-power electrodes with one of them being excited by an RF excitation frequency. The apparatus further includes means for generating and ejecting electrons from said second material only when the second material is exposed to the plasma, and means for increasing the energies of these generated electrons and accelerating these electrons into the etching plasma with sufficient energy to generate secondary electrons in the plasma. The apparatus further includes means for receiving a plasma discharge voltage signal, means for filtering the discharge electrical voltage signal to remove the RF excitation frequency and any DC components therein, and means for amplifying the natural frequencies of excitation and decay of the plasma discharge voltage perturbation signal, to thereby detect the processing endpoint. 
     In a preferred embodiment, the electron energy increasing and accelerating means comprises means for generating an electrode voltage sheath, and means for generating the electrons within this voltage sheath to thereby accelerate the electrons into the plasma. The electron generating means comprises means for directing a beam of photons in a selected energy range onto the item to be processed, which energy range is not sufficient to eject photoelectrons from the first material, but is high   enough to generate photoelectrons from areas of exposed second material.

Abstract: In the transmission of facsimile pictures, it is known to transmit the black-and-white data represented by only one binary position per picture element by means of a run length coding process. For the transmission of pictures in which the individual picture elements are represented by binary words having several binary digits, the individual binary digits of all binary words of in each case one picture line are successively subjected to a run length coding and transmitted. When a hierarchical code is used for representing the samples, a compatibility to previous facsimile receivers is given at the same time which then only process the highest binary digit. In addition, measures for preprocessing the samples are specified in order to obtain a smoothed sequence which can be transmitted more effectively by means of run length coding.

Abstract: An MOS integrated circuit for driving light-emitting diodes (LED's) comprises first constant current circuits, each of which is for one of the LED's and includes a first drive circuit for maintaining the drive current for the associated LED at a predetermined value established by a first reference voltage. The integrated circuit further includes a second constant current circuit which is connected to all of the first constant current circuits to form a mirror circuit with each of said first constant current circuits. A current detecting element detects a predetermined magnitude of current flowing therethrough and develops a current-representative detection voltage. A second drive circuit within the second constant current circuit responds to the detection voltage and a second reference voltage by maintaining said first reference voltage at a predetermined value so that the LED drive current is determined by the said detection voltage and second reference voltage.

Abstract: An improved retainer for surgical sutures (62) is provided which includes a suture retaining compartment comprising a suture winding panel (10) with the panel (10) having a pair of holding panels (14, 16) foldably connected to longitudinal edges of the suture winding panel (10). The holding panels (14, 16) are foldably connected to the winding panel (10) by at least three gussets (30, 32, 34) formed at the edges of the suture winding panel (10). The gussets (32, 34) at the ends of the foldable connection prevent frictional compression of the wound suture (62) at the corners of the retaining compartment, and the central gusset (30) or gussets engender a convex curvature to the holding panels (14, 16), thereby creating a low friction volumetric compartment which retains the suture (62) in place. The suture retainer also includes a needle (60) holding means (40) mounted at the intended location of the needle (60). In illustrated embodiments of the present invention the holding means (40) is angularly disposed with respect to the longitudinal dimension of the retainer to afford ease of needle (60) withdrawal, and in some embodiments the holding means (40) is located on a foldable needle park (84, 92) panel (80, 90). In some embodiments the retainer includes an insert (70) against which the suture (62) is wound. This insert (70) provides several features, including preventing snagging of the suture (62) on the needle (60) holding means during suture withdrawal, and protection of the needle point. The insert (70) may also include a flap (72) to prevent the suture (62) from snagging on a corner of the insert (70) during withdrawal.

Abstract: Filled food products have fillings of pH 4.3 to 5.4 and have been heated or otherwise treated to destroy vegetative organisms. If the water activity of the filling is also 0.92 or less, the product is shelf-­stable at ambient temperature without requiring packaging in an inert atmosphere. At water activities of 0.92 to 0.96 or less, an atmosphere of carbon dioxide is necessary. These particular combinations of features have been found to lead to particularly good eating qualities, even after re-heating.
