摘要： A light guide plate having a first surface and a second surface opposite the first surface receives light in a first direction parallel with the second surface and emits the light towards the first surface in a third direction perpendicular to the first surface. The light guide plate includes a light receiving portion which receives the light; a light guiding path which guides the light in the first direction; and an emitting portion which emits the light by reflecting the guided light towards the first surface in the third direction. The emitting portion includes a plurality of V-shaped grooves extending on the second surface in a second direction crossing the first direction. Each V-shaped groove extends in the first direction and is formed so as to be deepest in the center in the second direction and become shallower as a distance from the center increases.

摘要： A log management system for analyzing and managing a log acquired in a computer is provided. The system generates log groups each formed of log records with reference to the log. The system identifies active periods, in each of which a display area is active, in the log groups, and compares a start-to-end period from a start time to an end time of a reference log group selected from the log groups with active periods of subject log groups other than the reference operation log group individually to identify one or more subject log groups having an active period included in the start-to-end period. The system individually determines whether to include the identified one or more subject log groups in the same first cluster as the reference log group, based on an active period length of each of the identified one or more subject log groups within the start-to-end period.

摘要： A light guide plate includes an incident surface on which light outputted from point light sources is incident and an outgoing surface for outputting light incident from the incident surface. A reflection-and-propagation surface for reflecting light toward the outgoing surface is formed in a back surface opposite to the outgoing surface. The outgoing surface is made up of a propagation region adjacent to the incident surface, a propagation auxiliary region adjacent to the propagation region, a first diffusion-and-propagation region adjacent to the propagation auxiliary region, and a second diffusion-and-propagation region adjacent to the first diffusion-and-propagation region. The propagation region, the propagation auxiliary region, and the first diffusion-and-propagation region control hot spots and bright/dark lines in vicinities of the incident surface, while the second diffusion-and-propagation region controls viewing-angle characteristics of the light guide plate.

摘要： An automatic focusing apparatus repetitively detects a defocus amount of a photographing lens, discriminates whether or not an object is moving, and calculates a pursuit correction amount for a moving object on the basis of present and previous defocus amounts. When a non-moving object is discriminated, a drive amount of the lens is calculated on the basis of the present defocus amount, and when a moving object is discriminated the drive amount is calculated on the basis of a pursuit drive amount as a sum of the present defocus amount and the pursuit correction amount. A pursuit enable/disable determining device determines whether the drive amount is calculated on the basis of the discrimination result or on the basis of the present defocus amount. When a drive direction of the lens is reversed, the pursuit enable/disable determining device causes calculation of the drive amount of the photographing lens on the basis of the present defocus amount for driving the lens in a predetermined number of drive operations after the reversal.
