In a communication device which can realize a protocol conversion by a single device without preparing respective packages for existing various protocols, a protocol attribute included in a packet received is detected, protocol processing order data indicating a protocol processing order based on the protocol attribute are generated, and a plurality of protocols within the received packet are processed based on the protocol processing order data.

Communication device

A clean transfer method and an apparatus therefor capable of receiving, storing and transferring a transferred object by means of a vacuum clean box while eliminating arrangement of any vacuum evacuation means and transfer means in the vacuum clean box, as well as facilitating connection of the vacuum clean box to various processing units. The vacuum clean box is free of any vacuum evacuation means and transfer means and is provided with a first opening selectively closed with a first shutter and kept airtight when the first opening is closed with the first shutter. The vacuum clean box is airtightly connected to a sputter unit which is provided with a second opening selectively closed with a second shutter, when the first and second openings are closed with the first and second shutters, respectively, resulting in forming a closed space therebetween through which the first and second shutters are opposite to each other. Then, the first and second openings are released from the first and second shutters to permit the vacuum clean box and sputter unit to communicate with each other.

Clean transfer method and apparatus therefor

A clean transfer method and an apparatus therefor capable of facilitating storage and transfer of transferred objects by a vacuum clean box and realizing transfer of the objects to various processing units other than a vacuum unit. A vacuum clean box and a clean unit are airtightly connected to each other. The vacuum clean box includes a first shutter acting also as a lid and arranged so as to airtightly close a first opening of the box. The clean unit is provided with a second opening selectively closed by a second shutter. Airtight connection between the vacuum clean box and the clean unit is carried out while keeping the first and second openings closed by the first and second shutters, respectively, to thereby form a closed space therebetween which the first and second shutters face. Then, the closed space is evacuated to a vacuum, followed by opening of only the first shutter. Subsequently, a clean atmosphere which is substantially identical with a clean atmosphere in the clean unit is formed in the closed space and the second shutter is opened to introduce the first and second shutters into the clean unit.

A cooling arrangement for a laser beam printer apparatus which contains an optical box containing a laser beam deflector, a plastic lens which transmits a deflected laser beam, and an electronic package board. A cooling fan draws air in from the outside of the apparatus and passes the drawn-in air through the cooling fan directly to the optical box. To achieve more efficient cooling of the apparatus: (1) a portion of the electronic package board is projected from the optical box, and at least some heat-generating components of the electronic package board are provided on the projected portion; (2) the optical box and the electronic package board are arranged apart from each other, intervened by a recording sheet conveying unit; and/or (3) the optical box is provided with cooling fins. Specific cooling of the optical box is achieved by providing the cooling fan near to the optical box and electrically connected to the optical box.

Laser beam printer with cooling arrangements for optical box

A clean transfer system having a first vacuum chamber with a first transfer port, a first shutter for opening and closing the first transfer port and a first connecting member surrounding the first transfer port. The first connecting member is provided with at least an exterior portion. A second vaccum chamber includes a second transfer port, a second shutter for opening and closing the second transfer port, and a second connecting member surrounding the second transfer port. The second connecting member has at least an exterior portion. A closed space is formed between the first and second connecting members, so that the first and second shutters are movable within the closed space.

Apparatus for clean transfer of objects

A deflection scanner has a container for accommodating a deflector and lens. The deflector is adapted to be rotated by a driving motor which is supported by a bearing so as to deflect and scan a light beam emitted from a light source. The housing of the driving motor is fixed on the container by use of an elastic member instead of screws.
