Abstract: ABSTRACT OF THE DISCLOSURE           A locking jaw machine vise which includes a fixed jaw rigidly mounted on a frame, and a movable jaw slidably mounted on ways or guides for movement toward and away from the fixed jaw.  The sliding jaw is driven by an actuating nut and screw.  The actuating nut has an inclined surface that interlocks with the sliding jaw to provide a downward force on the sliding jaw to prevent the sliding jaw from tilt-ing when it is clamped.  A set screw is provided on the de-vice to limit the amount of movement of the movable jaw to-ward the actuating nut to minimize any tendency of the jaw and the nut to bind on the ways or guides used for the sliding jaw.

Abstract: ABSTRACT OF THE DISCLOSURE       A vent valve in a hydraulic system opens, when the system is initially pressurized, to allow the escape of air or other gases and closes automatically after the air is expelled when the oil or other operating hydraulic fluid in the system enters the valve because of the greatly increased viscosity of the hydraulic fluid.  The main valve member is a ball which is moved upwardly to engage a seat by the hydraulic fluid and the rate of flow around the ball is limited by the diameter of the passage and an inlet orifice to the passage.  On the outlet side is a ball check valve which is spring-biased to prevent air from flowing in a reverse direction back into the system, and restricted diameter vents pro pro- a restriction on the flow of air out of the system and aid i preventing premature closing movement of the main valve ball under high volume flow conditions.

Abstract: A MARK SIGNAL AMPLIFIER            Abstract of the Disclosure This invention relates to a mark signal amplifier for use in apparatus for electron-beam lithography.  It includes a first circuit for taking maximum and minimum values out of a mark signal that is detected by causing an electron beam to scan a mark area provided on a sample.

Abstract: ABSTRACT OF THE DISCLOSURE           A triangle waveform having substantially linearly sloped, gradually increasing and decreasing edges and having a frequency nf is generated from an n-phase sine wave signal, each phase having a fundamental frequency f.  A segment of any of the n-phases of the sine wave is detected when that segment is within a predetermined angular amount from a reference crossing level, such ax the zero crossing of the sine wave signal.  Successive ones of the detected segments are selected to synthize the triangle waveform.  In the preferred use of this invention, the triangle waveform is compared to a reference signal, such as the sine wave signal from which the triangle waveform is generated, this reference signal having a controllable frequency and amplitude.  Pulse transitions are generated at the intersection of the triangle waveform and each of the respective phases of the reference signal.         In one embodiment of this invention, the frequency of the. triangle waveform is increased by an amplitude-folding technique wherein the triangle waveform (of frequency nf) is folded about a pair of equal but opposite folding levels whenever the triangle waveform reaches either of these levels so as to produce an amplitude-folded triangle waveform of frequency mf and of peak levels determined by the folding levels.                    -i-

Abstract: This invention concerns a manufacturing process with which it is possible to manufacture reticles directly by means of a pattern generator without using an emulsion plate. In the direct process, a substrate comprising a glass plate coated with a chrome layer is coated with a positive-type photosensitive resist layer of a thickness resonant to the wavelength utilized by said pattern generator, and then exposed and developed according to the required configuration in a high intensity pattern generator. The chrome is plasma-etched and, finally, the resist is removed to produce a reticle with the desired pattern. In order to obtain a reversed contrast pattern, the substrate, after developing, is coated with a thin metal layer, such as aluminum, and then the resist is lifted off together with the metal. The exposed chrome, in its turn, is removed. The metal can, in its turn, be optionally etched. The reticles are utilized to manufacture masks which are involved in the photoligraphic steps of integrated circuits.

Abstract: 21)DSH-2520 FIXED GATING SESQUENCE APPARATUS   AND METHOD FOR AN INVERTER               ABSTRACT OF THE DISCLOSURE         A fixed gating sequence apparatus and method for an inverter is disclosed. In one aspect of the invention, an outgoing signal of variable frequency is generated by the inverter in response to gating signals provided by the inverter control. The gating signals effectively are provided by a shift register of an inverter control to the gates of the conduction controlled rectifying devices in the inverter in response to clocking signal. The clocking signal is provided to the clock input of the shift register at a normal system rate when an idle condition (idle control signal) is not present and at a predetermined cycling rate from when the idle condition occurs until a desired fixed gating pattern effectively is provided by the shift register to the inverter. The shift register remains at the stage providing the desired fixed gating pattern until the idle condition no longer is present, whereupon the normal clocking signals are again provided to the shift register. In another aspect, the gating signals, which effectively are normally supplied to the conduction controlled rectifying devices of the inverter, are blocked or inhibited from when the idle condition occurs until the desired fixed gating pattern is provided by the shift register of the control stage of the inverter. Thus, in this aspect, the inverter does not produce a moderate frequency burst of outgoing signal when the shift register cycles through and stops at the desired fixed gating pattern.
