A rotary type capping apparatus for screwing caps onto the mouths of containers includes a turn table provided with a plurality of container holders fixedly mounted along the periphery thereof, a main motor for rotating the turn table in a predetermined direction and a capping head assembly including a plurality of cap holders, each of which is disposed above the corresponding one of the plurality of container holders, so as to be movable closer to or away from the turn table. In one aspect of the present invention, the capping apparatus includes at least one motor exclusively used for rotating the cap holders for causing the caps held by the cap holders to be screwed onto the mouths of containers. In another aspect of the present invention, the capping apparatus is so structured to increase the torque applied to a cap until it has reached a predetermined level during the cap screwing operation thereby insuring that all caps may be screwed on as tightly as desired.

In an inter-subsystem communication system which has a communication queue enqueued by one subsystem having processors and dequeued by another subsystem having processors, there is provided between the subsystems direct memory access means which permits either of the subsystems to directly access a memory of the other subsystem, and in a queue element enqueued by the one subsystem is inserted memory access control information necessary for accessing the one subsystem, whereby a high-grade function is performed by the plurality of subsystems. When the source subsystem issues an enqueue command, the queue element length of a queue element produced in response to the queue command is compared with a remaining space of the queue and, if the comparison result satisfies a predetermined condition, an overflow interruption is caused in the processor of the source subsystem, thereby to efficiently detect a queue overflow state or queue usable state.

Disclosed is a process for producing a phosphine derivative from a phosphine oxide derivative, which comprises the following steps: (I) mixing a phosphine oxide derivative represented by formula (1) with a chlorinating agent in a polar organic solvent to cause the reaction between these components; and (II-1) adding a salt of a metal having an ionization tendency equal to or lower than that of aluminum to the reaction mixture and carrying out the reductive reaction in the presence of aluminum or (II-2) subjecting the reaction mixture to electrolytic reduction, thereby producing a phosphine derivative represented by formula (2). ArnR3-nP═O (1) ArnR3-nP (2) In formulae (1) and (2), Ar represents an aryl group such as a phenyl group, a phenyl group having a substituent, a heteroaromatic ring group, and a heteroaromatic ring group having a substituent; R represents an aliphatic hydrocarbon group or an aliphatic hydrocarbon group having a substituent; and n represents an integer of 0 to 3.

A stage apparatus includes a base, a stage movable on the base in first and second directions, a first member movable relative to the base in the first direction, and a second member movable relative to the base in the second direction. The first member is placed on the second member. With this arrangement, drive reaction-forces generated due to movement of the stage can be canceled by moving the first and second members, resulting in a smaller space needed for accommodating a canceling mechanism.
