Title: Photopatternable silicone polyamic acid, method of making and use
Inventor: BOLON DONALD A
IPC: G03F7/038
Filed: 1988-04-28
Granted: 1993-07-13
Abstract: RD-17,379 use of such silicone polyamic acid, as compared to "Pyralin" polyamic acid, it was found  that the problem of premature imidization also occurred during the drying of the applied silicone polyamic acid prior to the spin coating of the photoresist.  The work-life of the silicone polyamic acid as well as its usefulness during the development of the applied photoresist also was unsatisfactory.          The present invention is based on the discovery that certain silicone polyamic acids, resulting from the use of a siloxane containing norbornane bisanhydride (DiSiAn), shown by Ryang U.S. patent 4,381,396, assigned to the same assignee as the present invention,  in combination with benzophenone dianhydride (BTADA) and aryldiamine, have been found to resist excessive imidization during the initial drying step of the silicone polyamic acid after its application to a substrate. Temperatures up to 125°C for a period of 60 minutes can be used to make tack-free silicone polyamic acids which can be readily patterned during the development of a photopatterned photoresist.  Surprisingly, the patterned silicone polyamic acid thereafter can be readily removed if used as an antireflective coating.  The patterned silicone polyamic acid also can be fully imidized, rendering it substantially insoluble in conventional organic solvents, such as N-methylpyrrolidone in instances where it is used to make a color filter.             STATEMENT OF THE INVENTION           There is provided by the present invention, a method for patterning adherent silicone polyamide acid on the surface of at least a portion of a substrate, where the silicone polyamic acid is patterned by

Granted: 1990-12-04
Abstract: OSCILLATOR CIRCUIT                         Abstract An oscillator with noise rejection and a fifty percent duty cycle for the on-chip generation and conversion of a sine wave to a square wave, using an external reference crystal.  The circuit comprises a low gain current switch including a first and second switching transistors, with the control lines of the switching transistors connected to a reference voltage line.  The reference crystal is connected across the control input and the current receiving terminals of the first transistor so that a square wave is obtained at the current receiving terminal  of the second transistor.  A threshold circuit is included for adjusting the voltage of the square wave signal from the second transistor and applying the adjusted signal to a diode-coupled receiver circuit, which provides the output for the circuit.     This oscillator circuit provides a double action noise immunity through the use of a low gain current switch to prevent noise amplification, in combination with a diode-coupled receiver which is affected by noise only during signal transitions.  A duty cycle very close to fifty percent is realized by the circuit.

Granted: 1993-03-09
Abstract: SELF CLEANING STRAINER                   ABSTRACT OF THE DISCLOSURE    A  backwash  strainer  having  a  generally  cylindrical filter element made up of a stack of spaced rings that are triangular  in  cross  section,  with  the  bases  of  said triangular rings  disposed  in  a  cylindrical  surface.   A hollow backwash arm has an open slot disposed on the inside of the cylindrical surface which operates at a predetermined distance  from  said  element.   The  incoming water  in said strainer flows from the  inlet  up  through  the  straining element to the outlet.  The backwash arm receives water from around  the  straining  element,  which  flows  through  the element  into  the  backwash  slot  and out with the debris accumulated on said strainer.  Since the debris is supported on the flat interior of the rings, water flowing back into the arm into the slot  in the hollow backwash  arm  forces trash and other debris from the rings down to the backwash water outlet.   Water flowing through the clearance between the bars as used, helps flush the debris off the inside of the filter element.

Title: Phase shift divided leaky cable sensor
Inventor: HARMAN KEITH
IPC: G08B13/24
Filed: 1988-09-27
Granted: 1992-05-19
Abstract: ABSTRACT             A continuous wave (CW) leaky cable sensor for an intrusion detector is comprised of a pair of elongated parallel cables, one for establishing an RF field and the other for receiving the field.  A modulator is connected at an intermediate location of the receiving (or transmitting) cable, subdividing a detection zone into detection regions on each side of the modulator.  The modulator selectively modifies a signal received by a portion of the receive cable connected to its input.  By processing the signal at the output of the receive cable the detection region for either side of the modulator in which an intrusion has occurred can be determined.  The resolution of a CW sensor is thus increased at low cost.  Multiple modulators can be used at spaced locations increasing the number of detection regions, and thus the resolution.

Abstract: The lance holder for an oxygen lance has a substantially increased reliability and safety, since a valve disk slidable against the force of a valve disk spring by insertion of the lance is provided in a retaining body between the slag run back safety device and a gripping head. This valve disk is forced from the valve seat on insertion of the lance so that the refinery gas can pass through the lance holder without more. If through some error the lance is released, i.e. by slipping out from the holder, the valve disk automatically closes so that the oxygen gas provided can not flow through.          A contact of the oxygen-supply hose with the lance holder attached to it is thus reliably prevented.  At the same time the slag run back safety device and the clamping head are formed so that a very compact lance holder results.
