A cylindrical sliding bearing 1 can rotatably support a rotational shaft by a sliding surface 4 (inner circumferential surface). A crowning 5 having a sloped surface is formed at both ends of the sliding surface 4 in the axial direction. The crowning 5 includes a first crowning 3A formed of a sloped surface of a lining layer 3 and a second crowning 2A formed of a sloped surface of a back metal 2 positioned on the lower side of the first crowning. Unlike a conventional sliding bearing, the back metal 2 where the crowning 5 is positioned is provided as a sloped surface (2A). As compared with conventional bearings, the crowning 5 can be prevented from being unevenly brought into contact with the rotational shaft.

Operation keys are selectively invalidated according to the type of an information medium or recorded contents. The medium type of an information medium to be played back is discriminated in addition to detection as to whether or not the information medium to be played back includes information (ADV_OBJ file, etc.) unique to high-definition video information. If the discriminated information medium to be played back is an HD_DVD disc, or if the discriminated information medium to be played back includes an ADV_OBJ file or the like, operation keys (e.g., a repeat key) other than keys used in playback of the HD_DVD disc that records the high-definition video information are invalidated, and operation control is made in response to key operations other than the invalidated key operations.

A helically continuous projection 1a is formed around a sliding surface 1A of a sliding bearing 1 at a given pitch p. The surface roughness h of the sliding surface 1A, including the projection 1a, is chosen to be equal to or less than one-half the height H of the projection. This provides a sliding bearing 1 which exhibits an improved running-in performance.

A method of effecting serotonin-2-receptor antagonism in a mammal in need thereof, which includes administering to the mammal an effective amount of the compound of the formula (I), or a pharmaceutically acceptable salt thereof: wherein ring P, the dashed line, A, Y, Z1 and Z2 are defined herein.
摘要:
There is provided an alternative vehicle guiding system wherein a communication sever system receives a fault condition information from vehicles and also transmits the necessary information to the navigation system of an alternative vehicle in order to prevent the damage of loads by quickly guiding the alternative vehicle to the fault generating vehicle position and then realizing smooth transfer of remaining work to the alternative vehicle. The navigation system, fault monitoring means and vehicle communication means are respectively provided in the vehicles for transportation work and the center server system is also provided to transmit the vehicle distribution information to the vehicles. When a fault is generated in the vehicle, the communication server system receives the information from this vehicle and the navigation system of the alternative vehicle displays the transmitted information. Thereby, the alternative vehicle can always be distributed smoothly without any manual operation, the time required until the alternative vehicle arrives and the work transfer time can be shortened and adverse effect on the loads and successive load distribution work can be prevented.
