    • The present invention is an electric capacitance strain gauge provided with a pair of installing frames connected to each other, electrical insulating members with a stepped shape fixed onto the said pair of installing frames by insertion and two pairs of electrode plates with a stepped shape fixed onto the said electrical insulating members by insertion. As the electrical insulating members and the installing frames are positioned at a stepped part of the stepped shape when the electrical insulating members are fixed on the installing frames by insertion, and positioning of the electrode plates and the electrical insulating members is carried out at a stepped part of the electrode plates when the electrode plates are installed on the electrical insulating members by insertion, the relative positions of each member can be accurately determined. As the relative positions of each member of the electric capacitance strain gauge is accurately determined, the possibility that characteristics of the electric capacitance strain gauge are affected by each electric capacitance strain gauge is reduced.

    • There is provided polychromatic X-ray source used in a polychromatic X-ray diffraction apparatus, in which polychromatic X-rays are cast upon a sample to be analyzed, the energies of the X-rays diffracted from the crystallographic planes of the sample are measured and the physical properties of the sample are detected on the basis of the measured energies. The polychromatic X-ray source has a container made of radiation shielding material and having an X-ray outlet channel and the container contains therein a radionuclide for emitting radioactive rays and a substance for scattering and absorbing the radioactive rays emitted from the substance so as to obtain polychromatic X-rays. The polychromatic X-rays emitted from the substance travel through the X-ray outlet channel and are then made parallel through a Soller slit to be cast upon the sample. A slide door is provided in the channel so as to block the polychromatic X-rays if necessary.
