An apparatus for and a method of measuring permanent-magnet eddy-current loss is provided. A magnetic flux density measured in a Gaussmeteris fed back to a control device, and thus operation of a power supplyis automatically controlled. Accordingly, an experiment can be efficiently conducted. A non-magnetic and non-conductive measurement jigblocks heat generated in a permanent magnet sample from being dissipated to an iron core. Accordingly, eddy-current loss occurring in the permanent magnet samplecan be measured more precisely.

A core manufacturing apparatus using an inorganic binder includes a mulling sand feeder that supplies mulling sand comprising sand and the inorganic binder, a mold that receives the mulling sand from the mulling sand feeder and molds the mulling sand into a core, and a mold heating device that heats the mold. The mold includes an upper mold and a lower mold and has a plurality of cavities formed therein in which the mulling sand is deposited. The mold further includes an inner fluid channel through which fluid flows.

A tube-pin assembly for a heat exchanger of a vehicle includes a housing having an inlet into which exhaust gas flows; a plurality of tubes arranged inside the housing to provide a passage through which the exhaust gas flows; and cooling pins provided between the tubes to provide a coolant passage through which coolant flows, where a foamed metal made of a porous material is provided inside at least one of the tubes.

An injection mold for rotary-type gravity casting and a gravity casting method using the same are provided. The injection mold includes a molten metal-supply chamber that is selectively coupled to a die. The molten metal-supply chamber is also configured to, during gravity casting along with rotation, supply a pure molten metal into the die while collecting impurities contained in the molten metal and preventing the ingress of the impurities into the die.
