  • Patent number: 6631552
    Abstract: An electronic component mounting apparatus uses sensors and a controller to correct the position at which a component holder, generally a suction nozzle, captures a component, thus avoiding component capture errors and failures. More specifically, sensors detect a deviation amount between a predetermined location on a component absorbed by a suction nozzle and the suction position of the suction nozzle. The deviation amount is multiplied by a sensitivity coefficient, and the resulting adjusted deviation amount is then applied by the controller to correct the position of the suction nozzle when capturing a subsequent component. Accordingly, the subsequent component is absorbed by the suction nozzle normal to the component and at a position substantially centered with respect to the component, reducing the occurrence of suction errors.

  • Patent number: 6633731
    Abstract: Provided is an electronic view finder for use in a video camera apparatus that by making the relative position between an LCD and an ocular lens unit proper can decrease the rotatory polarization characteristic and can thereby enhance the contrast of the image. When a liquid crystal image screen surface has the characteristic of Viewing-Angle that this screen surface is seen with its contrast or brightness being different according to the direction in which to see the screen surface, the center of an eye-cup opening portion (6) on the light emission side of an ocular lens unit (2) is shifted from an optical axis (3) of the ocular lens unit (2). Thereby, an observer's eye is guided to a position detached from the position corresponding to the optical axis (3) to see the liquid crystal image screen surface (1) from an oblique direction. It has been thereby arranged to enable the liquid crystal image screen surface to be observed with an excellent contrast.

  • Patent number: 6632711
    Abstract: A polycrystalline thin film of good quality is obtained by improving a crystallization process of a semiconductor thin film using laser light. After conducting a film forming step of forming a non-single crystal semiconductor thin film on a surface of a substrate, an annealing step is conducted by irradiating with laser light to convert the non-single crystal semiconductor thin film to a polycrystalline material. The annealing step is conducted by changing and adjusting the cross sectional shape of the laser light to a prescribed region. The semiconductor thin film is irradiated once or more with a pulse of laser light having an emission time width from upstand to downfall of 50 ns or more and having a constant cross sectional area, so as to convert the semiconductor thin film contained in an irradiated region corresponding to the cross sectional area to a polycrystalline material at a time. At this time, the energy intensity of laser light from upstand to downfall is controlled to apply a desired change.
