  • Patent number: 9629292
    Abstract: An electronic component is mounted on a substrate according to a mounting mode which is set in advance in the following mounting information when component mounting work is performed. In the mounting information, any one of a first mounting mode in which an electronic component is transferred and mounted to a mounting position which is corrected based on a positional-shift amount between a position of printed solder and a position of an electrode and a second mounting mode in which the electronic component is transferred and mounted to the mounting position by considering only the position of the electrode as a reference, is set as a mounting mode for performance for each electronic component.

    Abstract: This liquid crystal display device (100) includes: a vertical alignment liquid crystal layer (30); first and second substrates (10, 20); first and second electrodes (11, 21) arranged on the first and second substrates to face the liquid crystal layer; and two photo-alignment films (12, 22). Each pixel region includes first and second liquid crystal domains, of which the reference alignment directions defined by the two photo-alignment films are a first direction and a second direction different from the first direction, respectively. The first electrode has a slit cut region (11R1), through which a slit (11s) has been cut to run substantially parallel to the reference alignment direction, in a part of a region allocated to each of the first and second liquid crystal domains. The width (W) of the slit is set so that when the highest grayscale voltage is applied to the first electrode, an effective applied voltage decreases by at least 0.

  • Publication number: 20160366380
    Abstract: A projector is provided, having a light source emitting a laser beam; an optical element, which the laser beam emitted by the light source passes through; a projection component, projecting an image onto a projection surface by irradiating the laser beam emitted from the optical element onto the projection surface while scanning. The optical element has an incident surface, where the laser beam emitted by the light source is incident; and an emitting surface, where the laser beam incident to the incidence surface is emitted. A first lens surface, shaping a beam shape of the laser beam from elliptic into circular by astigmatism generated in the laser beam, is formed on one of the incident and the emitting surfaces, and a second lens surface, converting the laser beam from a divergent beam into a parallel beam, is formed on the other one of the incident the emitting surfaces.
