    摘要: An automatic focusing apparatus includes a telephotographic system and a line sensor comprising multiple light receiving devices which receive light of an object image formed by the telephotographic system, multiple monitor sensors positioned adjacent to said line sensor, which monitor a quantity of light received by the line sensor, and a focus detecting device which controls a light receiving time of the light receiving devices in accordance with the monitor sensors, and detects a focusing state based on outputs of respective light receiving devices. When the focus detecting device fails to detect an effective focusing state, the light receiving time of the line sensor is controlled only by the monitor sensor positioned at a center.

    摘要: An automatic focusing apparatus includes a telephotographic system and a focus detecting device which detects a focus state of a plurality of variable sized, symmetrically shaped focus detecting portions by designating a center of a visual field of the telephotographic system as a center of the focus detecting device. A judging device judges a narrowest focus detecting portion as being effective among the focus detecting portions and which obtains a reliability of at least a predetermined value.

    摘要: An automatic focusing apparatus for a telephotographic system includes a telephotographic system which moves a focusing lens along an optical axis to control the focus, a focus detector which detects the focus state through the telephotographic system, a lens moving device which moves the focusing lens, a controller which drives the lens moving device in accordance with the focus state detected by the detector to move the focusing lens to thereby control the focus, and an external operation device which actuates the controller to perform the focusing operation. The controller continues the focusing operation until the focusing operation is completed when the external operation device is actuated.

    摘要: When a hybrid optical disc is loaded on a player, the next generation DVD layer is reproduced in preference to the DVD layer. Jump to the DVD layer is appropriately performed based on the content of the reproduction list held in the next generation DVD. The jump to the DVD layer is performed based on the command information (jump command) held in the reproduction list of the next generation DVD layer. When reproduction of the title specified by the command information is finished after the jump to the DVD layer, the process returns to the HDDVD layer, and reproduction is performed from the position following the reproducing position at the time of the jump. Thus, the content of the HDDVD layer and the content of the DVD layer are reproduced as one stream.

    摘要: A sleeve 10 for introduction of a pressurized fluid, which is attached to a rockbolt main body 1, comprises a cylindrical projecting part 11 of a large diameter and a bearing-plate-holding part 12 of a diameter smaller than an aperture of a bearing plate 6. The projecting part 11 and the bearing-plate-holding part 12 preferably has the same inner diameter. When the rockbolt main body 1 is embedded in a bedrock or ground, the bearing plate 6 locates on an edge of a rockbolt-setting hole of the bedrock or ground, and the bearing-plate-holding part 12 extends through the bearing plate 6 into the rockbolt-setting hole. Since the projecting part 11 and the bearing plate 6 are disposed on a sprayed concrete layer, a projection height of the rockbolt is remarkably decreased. Consequently, lining concrete 8 is applied onto the sprayed concrete layer with ease, and the bedrock or ground is reinforced with high reliability.
