In a liquid crystal display device provided with a backlight unit, creak reduction means is provided at least on one part of the areas where members constituting the liquid crystal display device such as the liquid crystal panel, the diffusion plate, the reinforcing plate, the frame of the liquid crystal display device and the back surface reflector for the backlight unit come into contact with each other. The creak reduction means may be a slippery film whose surface is fluorinated such as a fluororesin film, a polyacetal resin film, a polyethylene film, and a silicon coating film, or protrusions or protruding fins, or a friction reduction means such as silicon oil or fluorine oil, or a mutual displacement absorbing means such as a flexible sheet. By adopting such a constitution, it is possible to prevent noise from being generated due to mutual friction between the liquid crystal panel and the various members such as the diffusion plate, the reinforcing plate, the frame and the reflector for the backlight unit as a result of thermal expansion.

An improved bearing for a heat dissipation fan has an oil chamber for containing lubricant. The oil chamber has a sidewall extending between one open end and one closed end. The closed end is perforated with a through hole, and an edge of the sidewall at the open end is partially recessed to form at least one notch. An external surface of the sidewall is partially recessed along an elongate direction to form at least one oil slot aligned with the notch, the recessed external sidewall is further perforated with a through hole. An O-ring is disposed adjacent to the closed end of the oil chamber. The O-ring has an aperture aligned with the through hole of the closed end. An axial column is inserted into the oil chamber through the aperture of the O-ring and the through hole of the closed end. An external sleeve is used for receiving the oil chamber therein. The central axis column is operative to rotate within the oil chamber, such that the lubricant contained in the oil chamber is driven to flow upwardly through the notch into the oil slot. The axial column is so configured to prevent the lubricant from flowing external to the oil chamber via the through hole of the closed end.

The present invention discloses an extension to a prior-art genetic algorithm, with which the routing of elevators based on the calls given in an elevator system is formed. A new type of gene, a so-called run type gene, is connected to the chromosome of the genetic algorithm according to the invention, with which gene the desired speed profile for the elevator trip can be set. In this way e.g. an upper limit can be set for the acceleration or for the maximum travel speed of the elevator. By means of the run type gene a kinetic energy term is included in the optimization. The energy consumed by the system can thus be minimized more effectively by means of the algorithm, because the varying travel speeds of the elevators create more freedom of choice for the chromosomes of the algorithm.

A second input receives an analysis parameter threshold value for the used lubricant at the end of a service interval and stores the analysis parameter threshold value in a memory of the processor. A determiner predicts a future analysis parameter value of a mixture of used and fresh lubricant at the end of the service interval based on the analysis parameter value, and the analysis parameter threshold value.
