Abstract: ABSTRACT OF THE DISCLOSURE          A pump of the reciprocating plunger type for use in an oil well in which structure is provided for pulling downwardly on the pump plunger during its downward stroke rather than relying upon the pump rod or sucker rod to push the plunger downwardly thereby eliminating lateral deflection of the pump rod or the sucker rod and resultant wear and damage which frequently occurs especi-ally when pumping heavy crude oil or the like. One embodiment of this struc-ture involves a tension member connected with the walking beam and extending downwardly below the plunger, around a roller assembly or the like and then back upwardly for connection with the bottom of the plunger so that as the walking beam moves downwardly to move the pump plunger so that tension member will be tension for pulling the plunger downwardly without applying compressive force to the pump rod or sucker rod. Another embodiment of this structure pro-vides a weight attached to the bottom of the  plunger with the weight being reciprocal in a closed chamber so that it is not in contact with the fluid being pumped. The pump barrel is provided with a desander between the plunger and the standing valve and is in the form of a rod projecting upwardly in the pump barrel for extending into the lower hollow end of the pump plunger for removing sand therefrom to prevent sand from filling or clogging the lower end of the plunger.

Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed for selectively modifying the electrical characteristics of MOS devices at a late stage in the fabrication process to form, for example, the "I" and "O" data locations of a ROM, or to form enhancement-and depletion-mode devices.  In one embodiment of the method, in addition to forming openings in the passivation layer to define location of bonding pads, additional openings are formed in that layer at locations at which a data bit of one of the two levels is to be formed.  Subsequently, an ion implantation is performed through the exposed underlying polysilicon gate structure to create an implantation layer at the channel regions of se-lected MOS devices, and thereby permanently alter the threshold voltages of these MOS devices.  Other embodiments of the invention are disclosed in which ion implantation is performed through openings selectively formed in other layers, thereby to form implantation regions at selected locations to modify selected MOS devices at those locations.

Abstract: ABSTRACT OF THE DISCLOSURE          The printing apparatus disclosed herein generates alpha-numeric characters of high quality, using a multi-pin printing head capable of forming discrete dots or pels, by controlling the actuation of the printing head with a timing resolution which is an order of magnitude finer than the nominal dot diameter so that a line smoothness for slanted or curved lines is obtained which is greater than that obtainable by a uniform matrix.  The printing head is repeatedly traversed or scanned across the paper to provide essentially parallel lines of scan separated vertically by a distance which is a submultiple of the vertical spacing of the pins so that overlapping dots may be provided in the vertical dimension.  By these means the apparatus facilitates the formation of smooth lines of essentially arbitrary slope or curvature.

Filed: 1978-09-06
Granted: 1981-09-08
Abstract: Abstract of the Disclosure.  An elongated borehole logging instrument includes a permanent magnet linear recipro-cating motor. The motor powers a sliding sleeve which has attached to its outer perimeter a series of reversible vanes. The vanes engage the mud cake or the borehole wall and thus generate a force opposite to the direction of the vane slant. The motor has a stationary electromagnetic field comprised of a plurality of coils connected to the control electronics. The floating outer sleeve has permanent magnets all oriented in the magnets are either repulsed or attracted to thus generate a reciprocating motion which transferred to the vanes moves the tool up or down, depending upon the position of the reversing actuator. The control electronics is responsive to the differ-ence between the velocity of the well logging instrument, functionally related to its acceleration, and the velocity of the well logging cable at the earth's surface. In an alternative embodiment, a friction reduction agent is ported into the bore-hole in response to the velocity difference. In other alterna-tive embodiments, the velocity of the well logging instrument is compared with the velocity of the well logging cable at the earth's surface to control the cable hoist drum and thus avoid the risk of overrunning the well logging instrument with too much cable.

Abstract: ABSTRACT     In order to enable high recording densities of SECAM          (Registered Trade Mark) color video signals in a plurality of adjacent tracks in a record medium while avoiding chrominance component cross-talk, prior to recording the chrominance components are processed so that chrominance components in ad-jacent tracks are in frequency interleaving relationship with one another so that cross-talk can be eliminated by means of a comb filter.  This is done by frequency converting the chromin-ance components with a frequency converting signal generated by an oscillator section and which changes in frequency in a pre-determined sequence.  The sequential chrominance subcarrier phase shifts inherent in a SECAM signal are simultaneously cancelled by means of a circuit in this connection an injection locked oscillator is provided with an output from a phase modu-lator which is used to frequency shift one of the chrominance subcarriers so that the oscillator can be injection locked to both chrominance subcarriers.  In a second embodiment, the chrominance signals are interleaved by frequency conversion using a single frequency, phase modulated signal.
