Abstract: The internal space of a package is divided by a midlevel wall into a top compartment and a bottom compartment. The top compartment is further divided to provide a radiator chamber that accommodates a radiator and a radiator fan. The midlevel wall has a spatial connection port that spatially connects the radiator chamber and the bottom compartment. There is provided a spatial connection port cover that hangs over the spatial connection port, but that is open sideways. The radiator is disposed to face the radiator fan from below. The radiator has one of sides (e.g., a left frame portion) thereof supported by a spatial connection port cover.

Abstract: In a cogeneration device, a space is formed on a base member that supports an engine and an electric power generator in order to store leakages from the engine in the space. A panel-fixing bracket is provided outside the storage space, at a predetermined distance from a vertical wall section forming a vertical wall of the storage space. A panel, which is a part of a package, is bolted and fixed to the bracket. This structure enables each panel to be fixed to the base member while preventing the leakages stored in the storage space from leaking out.

Abstract: An engine-exhaust-system apparatus includes: a main body that reduces noise generated by exhaust gas; and an exhaust outlet tube that includes an insertion section inserted into the main body, exhaust gas in the main body being discharged outside via the exhaust outlet tube, wherein the insertion section has an open end with a brim portion that spreads beyond a tube diameter of the insertion section.

Abstract: A system for use with a freezing liquid (refrigerant) spray refrigerator for foods, in order to purify the refrigerant contaminated with solid filth such as a scale of a fish, dust or the like. Removal of such solid filth from the refrigerant for purification and re-use of the purified refrigerant can be carried out by an arrangement, wherein the refrigerant once sprayed onto the foods for refrigeration and contaminated with solid filth such as a scale of a fish, dust or the like will be conveyed to a filter for separating the solid filth from the refrigerant contaminated with the solid filth; the refrigerant so treated will then be conveyed to a heater in order to heat the refrigerant thereby to flocculate a fat, blood or the like of the foods still remaining in the refrigerant; the refrigerant will further be conveyed to a filter to remove the coagulum; and the refrigerant so purified will finally be conveyed to a reservoir tank for re-use.
