Abstract: A tubular arrangement (5) the front end of which defines a fastener outlet is extendably and contractably mounted to a fastener driver body (1). A drive bit (2) is mounted within the tubular arrangement. A fastener feeder (7) is mounted to the tubular arrangement and contains a pair of fastener guiding plates (31, 32) opposite each other with a predetermined distance sufficient to pass a strapped fastener assembly (6). One of the fastener guiding plates (31) defines a fastener passage opening (46) for feeding a fastener (10B) into the tubular arrangement (5E) through a fastener feed hole (37) defined in the side wall of the tubular arrangement. A fastener feed mechanism (50) with a feed roller (49) intermittently engaging and advancing the strap (6) is provided. A fastener separation element (77) of a fastener separation mechanism (80) passes into and out of the fastener passage clearance through, presses the fastener and separates it from the strap (6) when the fastener separation element extends out of the fastener passage clearance, to feed the separated fastener (10A) into the tubular arrangement. First (8) and second (9) actuators both mounted to the fastener driver body actuate the respective fastener feed and fastener separation mechanisms.

Abstract: A current mirror circuit has an actively controllable feedback element in the form of a p-channel field effect transistor (28). The p-channel transistor 28 has its gate connected to the output of a differential amplifier (12). The opamp 12 is connected to form a feedback loop within the current mirror circuit. The negative input (14) of the opamp (12) is connected to receive at node (16) the drain voltage V1 of the first transistor (24). The positive input (18) of the opamp (12) is connected to receive at node (20) the drain voltage (V2) of the second transistor (26). The purpose of the opamp 12 is to tend to equalise the drain voltages V1 and V2 of the first and second transistors 24, 26. If the drain voltage V2 of the second transistor 26 increases relative to the drain voltage V1 of the first transistor 24 the output signal Vo of the opamp 12 will be such as to reduce Vgs of the transistor 28 and hence Ids thereby to reduce the drain voltage V2 of the second transistor 26. If the drain voltage V2 of the second transistor 26 falls below the drain voltage V1 of the first transistor 24 the output signal of the opamp 12 will be such as to increase Vgs of the transistor 20, and hence Ids thereby to allow the drain voltage V2 of the second transistor 26 to rise. In this way the nodes 16 and 20 are continuously biased equal.

Abstract: A system for purification of refrigerant within a storage container (58) includes a filter/dryer (72) for removing contaminants from refrigerant passing therethrough, and a refrigerant pump (74) connected to the storage container (58) to circulate refrigerant in a closed path from the container through the filter/dryer and return the refrigerant to the container. The system configuration is such that the refrigerant is in liquid phase in at least a portion of the closed path. A pressure-differential valve (100) has an inlet (121) coupled to a purge port (64) on the container (58) for receiving air captured within the container. Container air pressure at the valve inlet (121) is fed to one side of a flexible diaphragm (112). Circulating liquid refrigerant is passed in heat transfer contact with a sealed enclosure (116) containing liquid refrigerant, so that the refrigerant within the enclosure is at saturation pressure and acts on the opposing side of the diaphragm (112) in conjunction with a valve spring (134). The diaphragm (112) is coupled to a valve element (126) that lifts from a valve seat (128) to connect the valve inlet (121) to an outlet (122), and thereby vent air from within the storage container (58), whenever container air pressure exceeds refrigerant saturation pressure by a threshold that is determined in part by the valve spring.

Abstract: Describing in simplicity, this research-the new engine (herein after referred to YTRE) is related to a kind of triangular rotation instead of linear reciprocating motion, which comprises an oval rotor (2) set to revolve along three cylinder walls combined inside a cylinder block (1) to achieve a new combustion moving function of an internal combustion engine with smaller volume, less weight, less parts but stronger power so as military vehicle or vessels can be served with better capability and efficiency in the field. 
     The Three-in-One (three cylinders combined in one) principle means the three cylinder walls are incorporated into one unit in which a rotor rotates. It performs the function three times compared to a conventional cylinder. Since no linkage is used, and crank and most parts are commonly used, the size can be greatly reduced while the power is relatively increased. Because several intake (12) and exhaust ports (12) can be simultaneously used during each stroke, the efficiency in intaking and exhausting strokes is greatly improved which means the thermodynamics is fully utilized. The rotor is designed for circulation therethrough of air and engine oil, better lubricating and cooling effects can be achieved. The rotor is constantly disposed to contact the cylinder walls during its rotary motion around a circle, high compression ratio is simultaneously achieved as needed.

Abstract: This invention relates to a method of preparing poly(ethylene 2,6-naphthalene dicarboxylate) by the polycondensation reaction of ethylene glycol and dimethyl-2,6-naphthalene dicarboxylate, using a dimethyl-2,6-naphthalene dicarboxylate starting material which contains significant amounts of methyl hydrogen 2,6-naphthalene dicarboxylate as a contaminant. The methyl hydrogen 2,6-naphthalene dicarboxylate moiety is incorporated into the polymer structure by initially esterifying the methyl hydrogen 2,6-naphthalene dicarboxylate acid end-group with ethylene carbonate, in the presence of an amine or ammonium catalyst, before the polyesterification/polycondensation reaction is performed.

Abstract: An electrostatic clamp (10) is disclosed which is suitable for uniformly clamping workpieces such as semiconductor wafers (11) to a support such as a pedestal provided with electrodes (13, 14) in plasma processing reactors (15). A reference electrode (21) exposed to the plasma maintains the force applied at the positive and negative clamp electrodes (13, 14) at similar magnitudes by applying the plasma-induced bias voltage on the semiconductor wafer (11) as a mutual reference voltage to the electrodes (13, 14). In addition, the structure and composition of the electrodes (13, 14) are adapted to minimize the rf voltage drop across the clamp (10) and to decrease the time required for the clamp (10) to release from the pedestal (12) once the clamping voltages are removed.

Abstract: The venting of cooling chambers, e.g. for cooling the motor of a dirty water pump, is performed according to the prior art by means of a venting pipe (8) running through the cooling chamber (3) from top to bottom. In the case of pumps which draw the coolant (6) off via a coolant feed (4) from the pump chamber (7) and return it into the pump chamber (7) via a coolant return (5), there is the risk that the inside of the venting pipe (8) will become clogged by the possibly fouled conveyed medium which is identical with the coolant (6), thereby rendering proper venting impossible. It is therefore proposed to provide the upper end (9) of the venting pipe (8) with an automatically functioning valve (10) which under the effect of coolant (6) flowing into the venting pipe (8) automatically closes and opens when the coolant level drops below the upper end (9) of the venting pipe (8). <IMAGE>
