Abstract: A dry processing apparatus for plasma etching or deposi­tion includes a chamber for plasma processing having an external wall for housing a work piece with a surface to be plasma processed. A source of an induction field is located outside the chamber on its opposite side from the work piece. A radio frequency induction field applied to the chamber generates a plasma. The plasma is confined within the external wall in the chamber by magnetic dipoles providing a surface magnetic field for confining the plasma. The surface magnetic field is confined to the space adjacent to the external wall. An R.F. generator provides an R.F. generated bias to the work piece. The chamber is lined with a material inert to a plasma or noncontaminating to the work piece, and the induction source in the form of a spiral or involute shaped induc­tion coil is located on the exterior of the liner material on the opposite side of the chamber from the work piece. Distribution of gas to the chamber is uniform because a manifold located about the periphery of the chamber and an orifice formed by the surface of the chamber and the manifold admits gas from the manifold into the chamber at a uniform pressure about the periphery of the cover of the chamber. A surface magnetic field can be positioned adja­cent to the induction coil to confine the field at the top of the chamber. A capacitive or inductive reactance can be connected in series with the induction coil to adjust the R.F. generated bias.

Abstract: A linear or rotary disk memory drive having provision for compensating or cancelling track position syncopation. Due to interference among the magnetic fields of smagnetic dibits A,B,C,D recorded in and adjacent to a servo code field in a magnetic memory disk, magnetic field intensities are displaced, producing an indication of a track center displaced from the actual track center. A magnetic head tracking such displaced magnetic fields is consequently displaced from track center, which is unacceptable. Four phases of magnetic dibits A,B,C,D of servo code are recorded in each of at least four consecutive circumferential frames Frame 1-Frame 4 in a memory disk 1, in differing servo code formats or patterns of magnetic dibits. Magnetic head servo code signals CS derived from the magnetic fields of these servo code magnetic dibit patterns are logically processed in pairs (A-B), (B-A), (C-D), (D-C) to produce a signal having an AC component representing track position syncopation which is cancelled by filtering , leaving servo code signals CS (N,Q) accurately reflecting the position of the magnetic head with respect to a track center.

Abstract: 2.1. In order to actuate a ball hitch of the generic type, in which the ball hitch coupling is unlocked by means of a lateral manual movement, a multiplicity of individual parts are required which makes the manufacture of the ball hitch more expensive. The object of the invention is to make the ball hitch constructionally simpler in design and thus more economical to manufacture. 2.2. For this purpose, it is provided according to the invention that a tongue (9) of the handle (8) can be pressed against a spring-loaded, displaceably mounted locking bolt (10) counter to the direction of spring force. 2.3. The invention permits the tongue to be pressed directly against the locking bolt so that further force transmission elements are no longer required and it is possible to manufacture the ball hitch more cheaply. <IMAGE>

Abstract: An improved video signal processing circuit (63) in the high quality television system for alternating-­current driving a liquid crystal module (64) is disclosed. A reference signal is inserted into vertical blanking periods of a R signal by a reference signal generator (20) and switching circuit (4). The R signal in which the reference signal is inserted is converted into digital signals of n channels by an A/D converter (6). There exists difference in circuit characteristics among signal processing circuits for processing the respective digital signals. However, the signals signal-processed for each channel are supplied to microcomputer 21 through switching circuits (18₁-18 n ). Since the microcomputer 21 controls full scale level and offset level of D/A converters 9₁-9 n  and adders 11₁-11 n , the deviations produced among sampled video signals due to difference in circuit characteristics among channels can be reduced.

Abstract: Materials made with vinylidene chloride methylacrylate copolymer having a methylacrylate content of at least about 8 percent by weight. Single and multiple layer structures, including sheets, laminates, films, packages and the like, made with a layer of the subject vinylidene chloride methylacrylate copolymer benefit from improved properties of elongation, tensile energy absorption, secant modulus, and impact strength. Subjectively, such materials are quieter and softer than comparable films having lower methylacrylate content and equivalent additives. In the alternative, the materials can be made with lower levels of, or no, plasticizer additive, without a significant reduction in barrier properties.

Abstract: n pairs of light beams are applied to an optical disc (D) to form a plurality of beam spots (SP) thereon which are offset by 1/2n of a track pitch p, and n signals which are shifted p/2n in spatial phase are generated from detected output signals indicative of light beams reflected from the beam spots (SP). These n signals are multiplied to produce a tracking control signal whose spatial period is 1/n of the track pitch p. Alternatively, the optical disc has n pairs of wobbling pits or servo pits which are offset by 1/2n of a tracking pitch p are disposed on an optical disc, and the n pairs of servo pits are scanned by a light beam to produce n signals that are shifted p/2n in spatial phase. The tracking control method is effective to effect tracking control on an optical (D) disc whose recording tracks are arragnged at a high density that exceeds the spatial cutoff frequency of an optical system of conventional nature used with the tracking control method.

Abstract: A method for storing multiple scanned images of a response-marked form document comprises scanning a copy of the form document on which no response information has been marked, using a scanning method that detects substantially all visual information present on the form document and produces a pixel image thereof and storing that pixel image data in a computer storage device. Additional steps comprise scanning at least one copy of the same form document that has been marked with at least one response mark that absorbs light falling outside the visible spectrum, using a scanning method that detects only the presence of light outside the visible spectrum and that produces a pixel image of said at least one response mark, then compressing that pixel image to reduce the amount of pixel data used to represent areas of the form document bearing no response marks and storing the compressed pixel image data in a computer storage device. The visual scan pixel image and the image resulting from a scan for response marks can be merged together to produce a signal image that is comparable in quality and appearance to an image from a single, conventional visual-mode scan.

Abstract: By employing two independent, separate and distinct flow paths which are controllably sequentially opened during use in a single actuation operation, an error-free, spill-free flame and explosion proof liquid delivery/filling system is achieved. In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configuration, requiring an actuation force to controllably, sequentially open the flow paths. In addition, by providing a cooperating, mating liquid transfer assembly, the container on which the liquid delivery/filling system is mounted can be refilled with safety and ease, completely eliminating spillage of the liquid. In this way, a fully integrated, cooperating, liquid flow controlling system is realized.

Abstract: A wordline driver circuit for reading the contents of a Dynamic Random Access Memory (DRAM). The circuit is implemented in CMOS and is capable of pulling the word-lines (10) to a negative potential with respect to the substrate, thereby decreasing the access time. An NMOS pull-down transistor channel (24) is implemented as a P-well within an N-well. Applying a negative potential to the source of the pull-down transistor (24) permits the transistor to be switched so that a negative potential is applied to the wordline (10) when the NMOS pull-down transistor is gated into conduction. A PMOS pull-up transistor (23) is serially connected to the NMOS pull-down transistor drain, permitting the wordline (10) to be driven positively.
