    摘要： A titanium slab is appropriate for hot rolling, is produced by electron beam melting furnace, has superior linearity so that it can be fed into a hot rolling machine without performing breaking down process or other subsequent correcting process after production, and has good structure having no cracks at the corner parts. A process for production thereof is also provided. The titanium slab is directly produced by a mold of an electron beam melting furnace, and has the deformation of not more than 5 mm for the thickness direction versus the longitudinal direction and deformation of not more than 2.5 mm for the width direction versus the longitudinal direction, both per a length of 1000 mm of the slab. The process for production of this titanium slab for hot rolling has a step of using an electron beam melting furnace in which its rectangular mold has mold walls of a long side and mold walls of a short side, and a step of pouring molten metal from one of the mold walls of a short side. Furthermore, a mold having chamfered parts at the corner parts can be used in the process.

    摘要： The present invention provides an optical pickup device capable of properly suppressing coma aberration which occurs due to a relative tilt error between objective lenses. The optical pickup device includes: first and second objective lenses having different optical characteristics; a lens holder provided with first and second lens receiving cylindrical parts to which the first and second objective lenses are attached so that distance from the first objective lens to an optical recording medium becomes shorter than distance from the second objective lens to the optical recording medium without overlapping the objective lenses; and a buffer member formed in a cylindrical shape so as to surround the periphery of the first objective lens, and having a projection for preventing collision between the first objective lens and the optical recording medium, the projection being provided at an end on the optical recording medium side. In the optical pickup device, the second objective lens is fixed in the lens receiving cylindrical part, and a lens tilt adjusting and holding structure for holding the first objective lens so that tilt of the first objective lens can be adjusted is added to the buffer member and the first lens receiving cylindrical part.

    摘要： A noise reducing device captures image data obtained by capturing a field with an image capturing part and a plurality of blackout image data obtained by capturing the field with the image capturing part under a light shielded state. This device reduces non-correlative random noise in the plural blackout image data. With random noise reduced, fixed pattern noise appears more accurately in resultant as blackout image data B. This device reduces the fixed pattern noise in the image data by using this blackout image data B.
