Abstract: The present invention provides a process for producing a diacylglycerol, which comprises, reacting triacylglycerol with water and an enzyme to obtain a mixture comprising of diacylglycerol, monoacylglycerol and free fatty acid; removing water content in the mixture by way of dehydration; and separating monoacylglycerol, free fatty acid and residual triacylglycerol by at least one separation method to obtain a high-purity diacylglycerol. An oil or fat composition comprising of diacylglycerol obtained from the said process and phytosteryl esters and/or ferulic acid esters in an amount of from 0.5% to 25% by weight of diacylglycerol is also provided.

Abstract: Provided is a lead frame package with an expansion plane to minimize electrical parasitics introduced into the semiconductor chip's electrical system (e.g., power delivery system, signal loops, etc.). Also provided are methods for assembling such lead frame packages into various semiconductor packages. Generally, a lead frame package includes a down set die attach pad over an underlying bottom plate. Both the die attach pad and the bottom plate may be used as intermediary connections for either power or ground connections. As compared to conventional lead frame package having an intermediary connection, the lead frame packages of the present invention can provide for any combination of shorter wire bond lengths, more wire bond connections, improved power delivery system, or reduced amounts of electrical parasitics.

Abstract: A computer-implemented method is described for verifying bond pad position conformity with predetermined design rules corresponding to a padring design. The padring design includes a plurality of linear arrays of bond pads. Horizontal and vertical scribelines for the padring design are defined. A first one of the linear arrays of bond pads is selected. Each bond pad has associated position values. Bond pad position data are determined with reference to the scribelines and the associated position values. The bond pad position data are compared to the predetermined design rules. Where violations of the predetermined design rules exist, the violations are identified.

Abstract: An integrated circuit device package and method of assembling same is disclosed. The device package includes an interposer ring substrate having a hollowed out center mounted on a die attach pad, a die mounted substantially in the center of the die attach pad such that the die is encompassed by the hollowed out center. The package further includes a single-piece drop-in heat sink having a first and second disk shaped portions where the first disk shaped portion has a diameter that is different than the second disk shaped portion.

Abstract: A system for generating electricity which includes an internal manifold fuel cell stack having an anode fuel gas duct, an anode exhaust gas duct, a cathode air duct and a cathode exhaust duct and a plenum having a fuel gas inlet, an anode exhaust gas outlet, an air inlet and a cathode exhaust gas outlet, which plenum is adapted to deliver a fuel gas and air to the internal manifold fuel cell stack. At least one air preheat panel is provided having two parallel planar surfaces disposed proximate and parallel to the internal manifold fuel cell stack and forming at least one air duct between the two parallel planar surfaces, which at least one air duct extends parallel to the two planar surfaces and has at least one cold air inlet and at least one preheated air outlet. The preheated air outlet is in fluid communication with the cathode air duct. In accordance with one embodiment, the internal manifold fuel cell stack, plenum and the at least one air preheat panel are all disposed within a housing.

Abstract: A fuel cell stack (6) includes at least first and second cells (40) and a separator assembly (42). Each cell includes an anode (44), a cathode (46) and electrolyte (48) between them. The separator assembly includes a fluid separator (58) having a fuel side, an oxidant side, an anode spacer element (68) between the fuel side and the anode of the first cell and a cathode spacer element (80) between the oxidant side and the cathode of the second cell. The separator assembly further includes a cathode exhaust passageway(86), having an exhaust inlet (84) at the central region (82) of the cathode spacer element, and an anode feed passageway (64), including a continuous loop anode feed tube, located spaced apart from the cell peripheral edge, with radially inwardly and outwardly directed fuel outlets (76, 78). An air deflector (62) helps prevent radially inwardly moving air from contacting the anode while permitting the air access to the peripheral edge (102) of the cathode spacer element.

Abstract: A fuel cell assembly (2) includes a vessel (4) containing a gas-permeable, porous housing (16). A fuel cell stack (14), including cells (42) and interconnect plates (44), is contained within the porous housing. Each interconnect plate has oxidant and fuel sides (64, 60) adjacent to the cathode (58) and anode (62) of adjacent cells. Fuel (68) is supplied to the fuel side at positions (78) midway between the center (82) and the periphery (80) of the fuel side. Reaction products (90) are withdrawn from the center of the fuel side. Flue gas (100) is withdrawn from the center (98) of the oxidant side. Air is preheated as it passes through the porous housing to the fuel cell stack. The preheated air combusts residual fuel (110) flowing radially outwardly from the periphery of the stack to further heat the air to the stack operating temperature to eliminate any external preheating of the air.
