A method for manufacturing pellets of hot-melt ink which includes the steps of filling molten ink into a mold cavity defined by a first die and a second die of a mold, allowing the ink to cool down and solidify in the mold cavity, and heating at least one of the first and second dies for re-melting the surface of the ink pellet to facilitate its removal from the mold cavity.

A circuit module of the present invention includes a circuit board, a plurality of electronic parts mounted on one face of the circuit board, a tubular body provided in an upstanding manner on the face in surrounding relation to the electronic parts, a turned-back portion turned back inwardly at a predetermined height position of the tubular body, and a resin portion formed by a sealing resin which is filled in the tubular body to a height reaching a distal end of the turned-back portion such that the resin covers at least part of the electronic parts. With this construction, the two surfaces of the sealing resin and the turned-back portion are joined together, so that the joining strength increases, and there can be provided the circuit module which is of the thin type and has a high strength. Further, through holes are provided at a region of the turned-back portion exposed from the sealing resin, and therefore a cavity within the turned-back portion (within a U-shaped portion), which is due to expansion of residual gas, can be eliminated, and besides the development of a convex portion formed on the upper surface of the resin by a cavity formed in the resin by gas moved from the interior of the turned-back portion into the resin and also the development of a crater-like irregularity portion formed on the upper surface of the resin portion when gas within the frame passes to the upper surface of the resin can be suppressed.

Disclosed is a liquid cooling system for use with MRI positioned video projectors to dissipate heat from the projector light source through liquid cooling. The system includes a heat sink body for mounting to the projector light source, the heat sink body constructed of a material to transfer heat away from the projector light. A remotely mounted motor-driven pump provides fluid circulation, the pump is constructed and / or mounted so as to not to be effected by the MRI magnetic field. The pump is coupled to the heat sink block by use of flexible tubing that is constructed and arranged to provide heat transfer to the environment thereby maintaining the projector light source temperature at a reduced level. A liquid reservoir is fluidly coupled to the pump intake for use in maintaining liquid levels at an optimum position.

A method and apparatus for optimizing the forging of a workpiece that is moved along a longitudinal axis of a forging press. The method includes detecting the relative positions of the first and second ends of the workpiece along the longitudinal axis and calculating a length of the workpiece therebetween.

Aircraft fuel tank access door systems and methods incorporating one or more of an outer fuel tank access door completely encapsulated by a dielectric material and an inner fuel tank access door comprising at least one drainage feature are disclosed. These systems and methods reduce or prevent (i) fuel pooling on the inner fuel tank access door, (ii) moisture pooling between the inner and outer fuel tank access doors, and (iii) p-static build up and lightning attachment to the outer fuel tank access door to increase safety, reduce the likelihood of corrosion and ease installation of the fuel tank access door system.

The electric fuel oil pump suitable for fuel containing alcohol has a shell, an inner casing inside the shell to constitute together with the shell one cavity serving as the main fuel oil conveying flow channel, and a motor set inside the inner casing and with gap among its parts serving as the secondary fuel oil conveying flow channel. While over 80 % of the fuel oil is conveyed through the main fuel oil conveying flow channel, the rest flows through the secondary fuel oil conveying flow channel to lubricate and clean the inside parts and cool the rotor and the stator, so as to raise the work efficiency of the motor. There are one non-return valve set at fuel inlet hole inside the secondary fuel oil conveying flow channel and one conic friction pair at the lower bearing on the end of the vane wheel to further raise the operation reliability and safety.

Provided is a circuit module comprising a circuit substrate, a plurality of electronic parts mounted on one face of the circuit substrate, a cylindrical member so erected from that face as to enclose the electronic parts, a folded portion folded inward at a predetermined height position of the cylindrical member, and a resin portion constituted of such a sealing resin to cover the electronic parts at least partially in the cylindrical member as is filled to a level to reach the leading end of the folded portion. This constitution joins the sealing resin and the two faces of the folded portion so that it can provide the circuit module which has an increased strength and which is thin but has a high strength. Moreover, through holes are formed in such a region of the folded portion as is exposed from the sealing resin. As a result, it is possible not only to eliminate the cavity, which might otherwise be formed in the folded portion (or the C-shaped portion) by the expansion of the residual gas, but also to suppress the bulge, as might otherwise be created on the upper resin face by the cavity which is formed by the gas moved from the inside of the folded portion to the resin, or the crater-shaped undulations, as might otherwise be created in the upper face of the resin portion when the gas in the frame goes to the upper face of the resin.
