This method of producing a negative electrode includes a step of adjusting a heat transfer coefficient between a leg portion and a fixing portion so that at least one of leg portions and the other leg portions become different in the heat transfer coefficient by deforming the plurality of fixing portions by applying pressure to the plurality of fixing portions from the outside thereof to fix the leg portions to the fixing portions.

Production method of negative electrode, negative electrode, and X-ray tube device

This object aims to disclose a biological multi-directional observation device with measures to avoid an illumination backlight problem taken. In a preferable embodiment of the multi-directional observation device, a two-dimensional detector () is arranged right above a transparent specimen support () and a main image forming lens () is arranged right under the two-dimensional detector (). A fluorescence-side filter () which allows only a fluorescence component from a biological specimen () pass therethrough is arranged, if necessary, between the main image forming lens () and the biological specimen (). Reflection mirrors (M, M) are arranged on the down side of the specimen support (), wherein the reflection mirrors are optional systems for leading a light of an image of the rear side of the biological specimen () to the main image forming lens (). A light source device is provided to irradiate light to biological specimen (). A light source in the light source device is set at a position that is not in direct and indirect viewing fields () of the two-dimensional detector, so that the backlight problem is avoided and a vivid biological multi-directional observation image by the two-dimensional observation image by the two-dimensional detector can be acquired.

Biological image acquisition device

In order to reduce light leak influencing the detection capability of a fluorescence imaging apparatus, an interference filter and an absorption filter on an emission-side filter section are arranged serially in the traveling direction of the fluorescence. The interference filter and the absorption filter that are in use for such an arrangement block the waveband light equivalent to the excitation light irradiated onto a sample while fully transmitting the waveband light equivalent to the fluorescence.

Fluorescence imaging apparatus and method for detecting fluorescent image

Optical waveguide paths to observe a sample on a sample holder from a plurality of directions while guiding an image of light in each direction which is emitted out of the sample toward a direction of a two dimensional detector via a main imaging lens include an optical waveguide path which never receives the light directly from the sample. The optical waveguide path which never receives the light directly from the sample forms an image of the sample within a substantial focus range of the main imaging lens, and includes optical elements arranged such that a light beam after formation of the image proceeds toward a direction of the main imaging lens. Optical elements on at least one optical waveguide path are those for forming real images. Therefore, the main imaging lens images the sample and those real images in block on the two dimensional detector.
