Abstract: In forming very minute window patterns to a negative photoresist film that is required in the manufacture of highly packed semiconductor devices, false unexposed patterns are formed in the proximity of the minute real unexposed patterns, the false patterns having such width that, when developed after exposure to ultraviolet light or energy beam, photoresist film immediately below false patterns are unexposed but the photoresist under unexposed part is exposed to light by reason of light circling around under false pattern, with a result that the false patterns in the photoresist film substantially disappear after development. Such partially removed false patterns serve to negate swell-ing of the photoresist at the time of development and prevent obliteration of real window patterns or formation of burr-like parts where real window patterns are to be formed.

Abstract: "HITCH ASSEMBLY FOR FARM IMPLEMENTS"          ABSTRACT OF THE DISCLOSURE         A hitch assembly normally extends forwardly from the front of the implement towards the tractor.  However with relatively wide implements in use today, they cannot be pull-ed through gateways or long roads.  In the present invention, the hitch includes a main dog leg member pivotally extending from one end of the main front beam of the implement and a secondary member pivotally extending from the other end of the main frame beam and detachably latching into the main dog leg member at the angulation towards the front thereof.  This is in the field working position.  When it is desired to trans-port the implement, the latch is released and the tractor pulls the main dog leg member around through approximately 135° to align with the longitudinal axis of the implement.  A cable assembly operatively connects between the two hitch members and pulls the secondary member along side the main front beam.          An adjustable pivot connection between the hitch members and the implement allows limited rolling action of the main front beam when in the transport position but prevents this motion when in the field position as well as aligning the latching end of the second hitch member with the latch recess of the main hitch member when they are returned to the field working position so that automatic latching can take place.

Abstract: TITLE            REGENERATIVE HYDRAULIC INTERLOCK SYSTEM  ABSTRACT OF THE DISCLOSURE         A hydraulic yarding system in which the haulback and main drum are coupled to a primary drive motor and provided with a hydraulic interlock motor coupled to a planetary set in the haulback drive in an open loop hydraulic circuit.  The hy-draulic fluid from the interlock motor can be diverted to the hydraulic circuit for the primary drive motor through a pres-sure sequence valve and a directional valve.  In this manner, regenerative driving of the interlock motor by the load pumps fluid from the interlock circuit selectively in the desired direction to the primary drive motor and supplements the power available to the primary drive motor.  A preferred embodiment utilizes two pressure sequence valves in circuits to either the in-haul or out-haul fluid flow directions for the primary drive motor so that a diversion of fluid from the interlock circuit can occur at a lower pressure valve during out-haul.

Abstract: ABSTRACT OF THE DISCLOSURE         This stove is divided by a partition into a lower, combustion chamber, and an upper chamber which communicates directly with an exhaust opening in the stove.  A catalytic converter is removably mounted in an opening in the partition. A by-pass damper, which is connected to the stove door, is normally held closed over a by-pass opening in the wall of the lower chamber, when the door to the stove is closed, whereby all combustion gases from the lower chamber must pass upwardly through the converter and the secondary chamber to the exhaust opening. When the stove door is opened, the by-pass damper tilts by gravity into an open position so that combustion gases from the lower chamber pass directly to the exhaust opening rather through the upper chamber, and rather than being accidentally discharged out of the open door.  The converter causes all by-products of combustion to be subjected to a secondary combustion in the converter before passing to the exhaust opening.  A fan blows air under pressure into a space formed between the stove and a surrounding heat shield thereby to distribute more heat, and to prevent overheating of the walls of the stove.  Primary combustion air is admitted by a damper to the bottom of the stove, and secondary air is admitted through an opening in the stove door around the edges of two glass panes which are mounted in the door.

Abstract: ABSTRACT OF THE DISCLOSURE           An arrangement for sensing the operating condition of an alternating current machine employs a Hall switch on the stator which is subjected to the alternating magnetic field established during operation.  The Hall switch has a magnetic field strength threshhold below which it will not be actuated.  During normal operation of the machine, the alternating field strength will cyclically exceed the switch threshhold, thereby generating a series of pulses at the frequency of alternation of the field. Should the field strength decrease as a result of overload of the machine, a decrease in line voltage, or the like, to a level below the threshhold level of the switch, the pulse output of the switch will cease.  Circuitry responsive to the absence of periodic pulses actuates an indicator circuit to warn of the faulty operation.
