Abstract: To provide an electric precipitator for a press mold, which can collect more reliably dusty foreign matter emitted during stamping process utilizing an electrostatic force, has excellent installability, and can be used safely. Provided is an electric precipitator for a press mold, the electric precipitator being used together with the press mold to collect dusty foreign matter emitted during stamping process by an electrostatic force and including: a laminated sheet in which a dust collection layer that holds the dusty foreign matter in contact, a first electrode layer, a second electrode layer, an insulation layer, and a close-contact fixation layer for installation on and fixation to a mold to be used are laminated; and a power supply device that applies voltages across the first and second electrode layers.

Abstract: In a wrapping type transmission structure for internal combustion engines, provided with a first wrapping type transmission system which includes a first tensioner urged into press contact with a first endless power-transmitting belt and which is disposed on a side wall of an engine body, and a second wrapping type transmission system which includes a second tensioner urged into press contact with a second endless power-transmitting belt and which is disposed at a location remoter from the engine body than the first wrapping type transmission system, a support shaft is fixed to the engine body and is inserted through the first and second tensioners which are relatively movable in a plane perpendicular to the axis of the support shaft, while permitting the movements of the tensioners in directions of press contact with the first and second transmitting belts. This enables the tensioner arrangement to be compact and permits an increase in freedom for disposition of the transmission systems.

Abstract: A filter medium for filtration of a fluid to flow therethrough from an upstream side to a downstream side thereof, said filter medium comprising a substrate having a density gradient wherein the density is high on the upstream side and low on the downstream side of the substrate.
