  • Publication number: 20110124259
    Abstract: An apparatus for manufacturing a light source and a method therefor are provided that enables a high efficient light source to be manufactured even when an optical element whose characteristic significantly varies is used. After maintaining temperatures of a laser device and a wavelength conversion element at a temperature where an output of light emitted from each of the device and the element is equal to or greater than a predetermined rate of the maximum output, the laser device and the wavelength conversion element whose temperatures have been maintained are joined together so that the output of the light emitted from the wavelength conversion element is equal to or greater than a predetermined value.

  • Publication number: 20110122898
    Abstract: Because a reflector that reflects a fundamental wave generated from a solid-state laser element and forms an optical resonator is disposed on an exit surface of a wavelength conversion element, the fundamental wave cannot be resonated and amplified in a stage before the wavelength conversion element is joined to the solid-state laser element. As a result, a problem is created in that the solid-state laser element emits low level light output, so that a relative position of the semiconductor laser and the solid-state laser element cannot properly be adjusted. In order to overcome the above problem, even in the stage before joining the wavelength conversion element to the solid-state laser element, the invention enables the semiconductor laser and the solid-state laser element to be joined by properly adjusting the relative position of the laser and the laser element.

  • Patent number: 7480410
    Abstract: An image recognizing method is provided, which includes the capability of efficiently recognizing characters such as letters and numerical characters included in an original image with accuracy when at least one of the characters is composed of plural elements. In this method, the elements in the original image are extracted to obtain a second image, in which each of the elements is enclosed by a rectangular frame. Then, a composite image is prepared with respect to a combination of the rectangular frames in the second image. After calculating a characteristic amount of the elements included in the composite image, the characteristic amount is input in a back-propagation network, in which learning about a reference character(s) to be included in the image has already finished, so that a degree of agreement between the characteristic amount of the composite image and the reference character is obtained.
