摘要： A dropping model electrostatic levitation furnace which puts a charged sample in levitation state by an electric field generated between electrodes and subjects the sample to heat treatment, in which a drop tube evacuatable in vacuum is connected vertically at the lower side of a furnace body to allow the sample to drop through the drop tube with a beam irradiating optical system having a heating laser beam. This brings experimental results which the influence of an electric field and gravity is eliminated sufficiently by means of a furnace having comparatively simple constitution, and also enables to reduce the cost drastically with high experimental environment.

摘要： The present invention is an electrostatic levitation furnace which is provided with a vacuum chamber, main electrodes opposed to each other within the vacuum chamber, an auxiliary electrode moving a sample levitated by an electrostatic field generated between the main electrodes, and a laser irradiator irradiating a laser beam on a sample displaced at a predetermined position, wherein a plurality of the main electrodes are arranged at proper intervals in a vertical direction to form electrostatic field generating interspaces between the adjacent the main electrodes respectively, auxiliary electrodes are arranged to correspond to each of the electrostatic field generating interspaces, the laser irradiators are arranged both of above the main electrode positioned uppermost and under the main electrode positioned lowest so as to be opposed to each other coaxially, and the main electrode positioned midway between the uppermost one and the lowest one has a through-hole on optical path of laser beam which a sample can be passed through. The electrostatic levitation furnace, for example, when two species of samples are fused together, regardless of whether or not the samples are conductors, has the function of melting the samples being levitated individually and fusing them together while maintaining each of the temperatures of the samples, and consequently this enables to actualize a fusion in a state excluded external interference.

摘要： The present invention is an image pickup device provided with a CMOS camera which is provided with a telecentric lens to photograph a sample put in a levitation state at the center inside an electrostatic levitation furnace, a metal halide light source which is positioned on the opposite side of the sample from the CMOS camera to irradiate light with a wavelength of 400 to 450 nm toward the sample, and a digital signal processor which performs image processing for enhancing an edge of an image captured by the CMOS camera in real time to output a position of center of gravity of the sample put in the levitation state, where a blue filter is attached to the CMOS camera. Even if the sample becomes incandescent due to a high temperature, contrast of the sample against a background can be obtained by the image pickup device. In addition, position information required for levitation control of a sample with a complicated shape is outputted by the image pickup device so that an instant at which the sample with a complicated shape changes to a spherical shape one can be specified visually.
