Abstract: A method for mounting food products or the like, has the steps of: (a) transferring food products on a continuously moving conveyor in a column; (b) detecting the food product by a food product detecting sensor attached to a predetermined position of the conveyor, wherein each food product is transferred with position data thereof given by a control unit; and (c) mounting each food product at a preset position on a receiving surface with a food product discharge end section of the conveyor being caused to withdraw at a speed corresponding to the position data thereof.

Abstract: A process for producing polyolefin with a vapor-phase fluidized-bed reactor, wherein the reaction is started after filling the reactor with particles which contain moisture and/or molecular oxygen and can form a fluidized bed in order to prevent the formation of molten resin which is liable to occur at the start of the reaction and to attain a smooth operation of the reactor.

Abstract: A closed rotary compressor includes a generally cylindrical sealed vessel having an oil sump defined therein for accommodating a quantity of lubricating oil, a drive unit housed within the sealed vessel and having a drive motor and a shaft driven by the drive motor, and a compressor mechanism housed within the sealed vessel. The compressor mechanism is provided with at least one set of compression elements.
