Abstract: The present invention relates to a radial tire for a heavy load comprising a bead core, a carcass ply layer, an inner liner A layer, a belt and a tread, wherein the following relational equation (I): P/G?1.00??(I) and relational equation (II): D?6.0??(II) are satisfied at the same time, and the radial tire for a heavy load which is improved in a low fuel consumption and in which a tire durability is consistent with a reduction in a weigh can be provided.

Abstract: A conferencing system prevents useless data processing that accompanies data communication from occurring even when a presenter's device that outputs image data is switched. A projector functions as a node in a tree structural network, and projects an image corresponding to image data and sends the image data to the direct child indicated in parent-child information when receiving the image data from the direct parent indicated in the parent-child information. A switching module, when receiving a switching request for making a request to switch a parent-child relationship from the direct child, sends the switching request to the direct parent, when receiving permission information representing permission to switch from the direct parent, sends the permission information to the direct child that sent the switching request and changes the parent-child information so that the direct parent becomes the direct child and the direct child that sent the switching request becomes the direct parent.

Abstract: In an image forming apparatus, a developing unit for developing a latent image on a photosensitive drum is detachably mounted in the apparatus and is provided with a identification signal generator for each particular developing unit. When the developing unit is replaced by a new one, an identification signal generated from the generator is compared in a CPU with reference identification data stored in a memory. When the generated identification signal differs from the stored reference identification data, the generated identification signal is stored as a new reference data in the memory and a toner concentration signal generated from the sensor is also stored as new reference toner concentration data in the memory. Thus, a desired toner concentration can be maintained even through developing units are replaced.
