The compression ring 21 is mounted on the seal ring 20 at the end thereof. The compression ring 21 has the outer circumference projections 30 that are fixed in the groove 40 extending in the axial direction at the inner surface of the flange 22 . With this construction, the compression ring 21 can move in the axial direction and is stopped in the rotational direction. The compression ring 21 is pressed by the springs 23. Thus the compression ring 21 works as a stopper to stop the rotation of the seal ring 20 and as a spring receiver.

摘要:
A method for separating a desired component from a solid mixture by repeated recrystallization in a single vertical crystallizer having a plurality of chambers partitioned by solid-liquid separation means, which comprises intermittently feeding a solid mixture to the top chamber and a solvent to the bottom chamber, dissolving the solid in each chamber in the solvent by heating after feeding of the solid mixture to the top chamber, transferring the resulting solution in each chamber to the adjacent lower chamber while taking out from the bottom chamber the solution from which the desired component is recovered as an end product, cooling the solution in each chamber to precipitate crystals, and transferring the resulting mother liquor in each chamber upwardly through the separation means not capable of passing the resulting crystals by the feeding of the solvent to the bottom chamber, while allowing excess mother liquor to overflow from the top of the crystallizer, the above procedures being repeated continuously. The crystallizer suitable for practicing the method is composed of a tower having a feed port for feeding the solid mixture and a discharge port for overflow of the excess mother liquor in the upper end portion, a feed port for feeding the solvent and a discharge port for taking out the solution in the lower end portion, separtion means for separating solid and liquid by which the tower is divided into chambers, and means for heating and cooling the content in the tower.

摘要:
A major object of this invention is to provide a remote diagnosis apparatus, a remote diagnosis system, a user terminal, a program, a diagnosis program, and a storage for easily diagnosing a pigmentary deposition portion. A user of the system picks up the skin having benign nevus pigmentosus that might be melanoma through a dermoscope using a portable telephone with a camera to which the dermoscope is attached by means of an adapter, accesses to the Internet using an Internet connection function of the portable telephone, and sends the picked up skin image to the remote diagnosis apparatus. After receiving the skin image, the remote diagnosis apparatus uses the melanoma diagnosis program to examine the skin image for melanoma and a disease stage of melanoma if there is melanoma and then sends a result to the user.
摘要:
A sensor substrate 1 having on its lower surface a surface acoustic wave element 2 for detecting pressure is mounted on a supporting substrate 6 through a sealing member 4 surrounding a sensor section 2. A sealing space S is formed by the sensor substrate 1, the supporting substrate 6, and the sealing member 4, and the surface acoustic wave element 2 for detecting pressure is sealed hermetically in the sealing space S. Reliability can be enhanced by protecting the surface acoustic wave element 2 from the external environment.
