An antifouling paint is described, that contains as its essential components an antifoulant and a polymer of one or more of the monomers A represented by general formula (1) and/or copolymer composed of one or more of the monomers A and one or mroe vinyl polymerizable monomers B that are copolymerizable with said monomer A: ##STR1## wherein X is a hydrogen atom or a methyl group; n is an integer of 2 to 4; and m signifies the average degree of polymerization and is zero or a real number. The antifouling paint may contain a slipping agent as the third essential component to provide an even greater fouling resistance.

A heat treatment apparatus including a vacuum vessel, a substrate stage which holds a substrate mounted on it, a heating unit for heating the substrate, and an exhaust unit for evacuating the vacuum vessel includes a first reflector which covers the upper portion of the exhaust port of the exhaust unit while being spaced apart from the exhaust port, and a second reflector which surrounds the exhaust port. At least one of reflector members which form the second reflector faces a direction defined from the heating unit to the exhaust port.

There is disclosed a wireless communication apparatus that does not interrupt synchronous communication but can continuously perform the synchronous communication even when an address duplication occurs between the local wireless communication apparatus and a nearby wireless communication apparatus. A plurality of wireless communication apparatuses constitutes an ad hoc network system where they transmit beacons to each other. In the wireless communication apparatus, an address processing part (145) generates a first address, which includes a beacon period slot number corresponding to the position-on-beacon-period of a beacon generated by the local wireless communication apparatus, and a second address assigned at random. A beacon processing part (140) determines whether the second address generated by the address processing part (145) is coincident with a second address at another wireless communication apparatus. A transmitting part (170) uses one of the first and second addresses generated by the address processing part (145) to transmit a frame to the other wireless communication apparatus.

In the case where a screen divided display is performed on a liquid crystal panel, a change in brightness or chromaticity between sub regions divided may be reduced. A display includes: a display panel; a backlight arranged corresponding to each of sub regions, and selectively illuminating the corresponding sub region, the sub regions being defined by dividing a display region of the display panel into a plurality of parts; a monitoring means for monitoring the light emission state of the backlight corresponding to each of the sub regions; and a display control means for determining a sub region on which an image is to be displayed, on the basis of the monitoring result of the monitoring means, to fit the image into the determined sub region, and controlling a backlight corresponding to the determined sub region to emit light.

A radio communication device includes a communication data selection unit for selecting from the received radio communication data containing communication time reservation request information in which a time slot for performing data transmission source radio communication device is described and a communication information analysis unit for extracting an identifier of the source radio communication device and the data transmission reservation time slot from the communication time reservation request information in the radio communication data. When the received radio communication data is addressed to the local device, a communication/response information generation unit correlates the identifier to the reservation time slot, records them in a communication reservation table, and generates communication time reservation response information including information of the reservation time slot.

A distributed wireless medium access control protocol is disclosed. According to the disclosed wireless medium access control protocol the medium access time is partitioned into equal sized slots, and a predetermined number of the slots forming a superframe. The protocol defines beaconing devices and passive devices. Each beaconing device designates one of the slots in the superframe as its beacon medium access slot, and broadcasts during that beacon medium access slot a beacon frame to other devices in wireless range of that beaconing device. A beacon frame collision detection and resolution procedure, and a procedure for reserving access time for communication between devices are also disclosed.

A substrate heating apparatus having a conductive heater which heats a substrate includes a filament arranged in the conductive heater and connected to a filament power supply to generate thermoelectrons, and an acceleration power supply which accelerates the thermoelectrons between the filament and conductive heater. The filament has inner peripheral portions formed at a predetermined interval along an inner circle concentric with the substrate, outer peripheral portions formed at a predetermined interval on an outer circle concentric with the inner circle and having a diameter larger than that of the inner circle, and a region formed by connecting the end point of each inner peripheral portions and the end point of a corresponding one of the outer peripheral portions.
