Abstract: ABSTRACT          A method of making a high performance, small area thin film transistor having a drain region, an insulating layer, and a source region forming a non-coplanar surface with respect to a substrate is disclosed.  The insulative layer is formed in between the source and drain regions.  A deposited semiconductor overlies the non-coplanar surface to form a current conduction channel between the drain and source.  A gate insulator and gate electrode overly at least a portion of the deposited semiconductor adjacent thereto.  The non-coplanar surface can be formed by utilizing a dry process to simultaneously etch through several layers in a continuous one-step process.  A second dielectric layer may be formed above the three previous layers. Thus decouples the gate electrode from the source region by creating two capacitances in series, thereby limiting the capacitance between the gate electrode and the source region.

Abstract: ABSTRACT OF THE DISCLOSURE         An optical-electrical geophone which generates a binary signal is described.  The geophone utilizes an optical fiber for the return transmission of a light source in the geophone.  The geophone contains a light chopping means which oscillates in response to vibrations imparted into a geologic formation.  As the chopping means such as a baffle or a tubular member vibrates, it chops the light signal and creates an on/off light pattern, i.e., binary signal.  The light passing through a slit in the baffle or tubular member is returned to the seismic vehicle through an optical fiber for further processing.          The optical-electrical geophone creates a binary signal directly without the use of clipping electronics and magnets or coils used in conventional geophones.

Abstract: SOLENOID CONTROLLED FLUID FLOW VALVE                          ABSTRACT     A remotely controllable fluid valve includes a solenoid armature arrangement which functions as an electro-magnetic spring having improved force-displacement characteristics over a mechanical spring.  The solenoid magnetizes a pair of axially spaced, sleevelike field poles.  The armature is so shaped and initially positioned relative to the field poles that:  as the armature, supported in one pole, moves further into the other pole, the axial magnetic force thereon decreases at a decreasing rate with the rate of decrease being greater at higher levels of solenoid energization.          In one embodiment, the flow valve is pressure compensated and controls a larger flow valve.  The valve seat is formed on a member separate from the housing which also slidingly supports the valve member.  The surfaces supporting sliding members are electroless nickel coated to reduce friction.

Abstract: PROGRAMMABLE FUNCTIONS FOR RECONFIGURABLE               REMOTE CONTROL                ABSTRACT OF THE DISCLOSURE        A reconfigurable remote control transmitter is disclosed that has the ability to learn, store and repeat the remote control codes from any other infrared transmitter.  The reconfigurable remote control transmitter includes an infrared receiver, a microprocessor, nonvolatile and scratch pad random access memories, and an infrared transmitter.  The microprocessor application is divided into four main categories:  learning, storing, retransmitting, and user interface.  In the learning process, the reconfigurable remote control transmitter receives and decodes the transmissions from another remote control transmitter.  The process is repeated at least twice for each key to make sure that it has been properly received and decoded.  Once the data has been received and decoded, it is stored for later use.  In order to do this, the received and decoded data is compressed so that it can fit into the nonvolatile memory.  This process is repeated for each of the several remote control transmitters that are to be replaced by the reconfigurable remote control transmitter.  While the learning and storing operations have been completed, the reconfigurable remote control transmitter is ready to use.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved method of manufacturing injection molding manifolds for multi-cavity molding.  The method includes gun drilling a longitudinal duct through a steel manifold body, drilling a transverse inlet duct to connect to an inlet on one surface of the manifold, and drilling diagonal outlet ducts to connect to spaced outlets on the opposite surface of the manifold.  The outlet ducts are smaller in diameter than the longitudinal duct to match the rest of the system.  Before the outlet ducts are drilled, end portions of the longi-tudinal duct are drilled out to a larger diameter and steel plugs having a tapered well are securely welded into them with the mouth of the well in align-ment with the longitudinal duct.  The plugs are larger in diameter than the central portion of the longitudinal duct to avoid the formation of thin knife edge portions where the outlet ducts join the longitudinal duct which often break down during use.           The smaller diameter outlet duct is then drilled diagonally to intersect the well in the plug at its smaller blind end.  The joint is then smoothly finished to remove any irregularities and provide a smooth transition between the larger diameter longitudinal duct and the smaller diagonal outlet ducts at each end.
