Abstract: A silicon drift detector has an X-ray detection device, an electrode terminal subassembly for electrical connection, a Peltier device, and first and second shields formed between the electrode terminal subassembly and the Peltier device. The first shield is made of a material consisting chiefly of an element having an atomic number smaller than the average atomic numbers of the elements included in the material of the Peltier device. The second shield is made of a material consisting chiefly of an element having an atomic number greater than the atomic numbers of the elements included in the material of the Peltier device.

Abstract: A throw-away tip is mounted on a first tip mounting seat of a pin mirror cutter. In the throw-away tip, cutting edges are formed at intersecting ridgeline parts between a pair of oppositely disposed long side faces of a substantially trapezoidal flat-plate-shaped tip body, and upper and lower faces of the tip body. A thickness direction of the tip body is approximately aligned with a radial direction of the cutter body to provide curved edges formed in acute corner parts of the tip body for cutting. The tip is mounted on a second tip mounting seat of the pin mirror cutter such that the thickness direction of the tip body is approximately aligned with an axial direction of the cutter body to provide curved edges formed in obtuse corner parts of the tip body for cutting.

Abstract: An X-ray analyzing apparatus according to the invention includes an excitation ray generator for applying an excitation ray onto a sample, and an X-ray detector which is sealed in a vacuum container along with a cooling device; a first X-ray passing layer, where a first gas exists, is provided in a path through which the characteristic X-ray generated from the sample travels to the X-ray detector; X-ray transmission windows are provided on the first X-ray passing layer and on the vacuum container so as that the characteristic X-ray can reach to the X-ray detector through the windows; the first and second X-ray transmission windows are separated from each other so as to provide a second X-ray passing layer therebetween; and the second X-ray passing layer is arranged to be a vacuum or a second gas is circulated through the second X-ray passing layer.
