Abstract: A method of manufacturing a radial tire is disclosed, wherein a tread ring is formed separately from a tire main body by the use of a tread ring forming apparatus. The radial tire comprises a belt having a camber and a band wound thereon. The tread ring is an annular assembly of a raw belt, a raw band wound thereon and a raw tread rubber. The tread ring forming apparatus comprising a belt drum made up of segments defining the drum circumference. In a cross section including the belt drum axis, the radially outer surface of each segment is a straight line parallel to the axis. In a cross section normal to the belt drum axis, the radially outer surface is an arc having one radius substantially equal to one half of the drum diameter, but the drum circumference is decreased in the belt edge portion than the central portion by increasing gaps between the segments.

Abstract: A photosensitive body for electrophotographical use has a conductive base body and a marking area provided thereon. The maximum surface roughness of a photosensitive layer provided right on the marking area is specified not to exceed 2.5 &mgr;m. And also, a ratio of the optical reflective index of the marking area to the optical reflective index of the non-marking area is specified to be in a range of 0.3 to 0.7. In this manner, even when the photosensitive layer is thin (not exceeding 25 &mgr;m), it is possible to prevent problems such as inadequate cleaning and toner falling. Hence, it is possible to offer a photosensitive body for electrophotographical use which can constantly produce high quality copied images.

Abstract: A mobile radio station PS1 in a mobile radio communication system shown in FIG. 1 receives a signal at a first interrupt time interval T1 or a second interrupt time interval T2.The mobile station PS1 sets an interrupt time interval and informs the interrupt time interval to a control station CS. The mobile station PS1 receives a signal at the set interrupt time interval.Receiving an incoming call from a calling station addressed to the mobile radio station PS1 which receives a signal at the second interrupt time interval T2, in case that the control station CS determines the calling station requires a simplex communication, the control station CS stores data addressed to the mobile radio station PS1 in the storing server SV, in case that the control station CS determines the calling station requires a bi-directional communication, the control station CS transmits a signal to the mobile radio station PS1.
