Title: Cylindrical mirror face machining method
Inventor: NARA MITSURU
IPC: B24B5/00
Filed: 1985-12-19
Abstract: PURPOSE:To machine a cylindrical mirror face accurately by making a frame elastically support, through a spring, a machining head for supporting a grinding wheel. CONSTITUTION:A machining head 2 for supporting a grinding wheel 1 is supported elastically by a frame 15 through a spring 3. Now when the periphery 7a of a cylinder 7 is machined, the cylinder is rotated round the center 4, 5 by a work carry 6. On the other hand, the grinding wheel 1 is rotated in the same direction as the cylinder 7. And then the periphery 7a is finished to a mirror face by repeatedly shifting the cylinder 7 by the specified amplitude in the X direction while pushing the periphery of the grinding wheel 1 toward the periphery 7a of the cylinder 7, against the force of the spring 3. In this case the cylinder 7 and the grinding wheel 1 made contact with each other elastically and are not subjected to any compulsory force, therefore the periphery 7a can be finished in an accurate mirror face.

IPC: B01D61/00
Filed: 1991-10-31
Abstract: PURPOSE:To separate a mixed solution efficiently by a vaporizing permeation method and to enhance the transmission speed of a separated solution to a practical level. CONSTITUTION:By making the vapor of a mixed solution 2 containing a plurality of liquid components permeate from a solution chamber 3 to a vacuum chamber 1 through a permeable membrane 4, the specific liquid component in the mixed solution 2 is separated by a vaporizing permeation method. As the permeable membrane 4, a silicone porous membrane 4a is used. The liquid component having high affinity to silicone in the mixed solution 2 passes through the pores of the silicone porous membrane 4a to permeate from the solution chamber 3 to the vacuum chamber 1 and liquid separation can be performed. As compared with a case of making a liquid component permeate by diffusing and infiltrating the same throughout a non-porous permeable membrane 4, the permeation speed of the liquid component to be separated through the permeable membrane 4 becomes extremely high.

Abstract: PURPOSE:To enable a camera to always receive the image of an object with appropriate illuminance even when the temperature of the object fluctuates by measuring the temperature of the object before taking the image and adjusting the opening of the camera in accordance with the measured temperature and sensitivity of the camera. CONSTITUTION:A lens unit 3 with an opening adjusting mechanism is provided at the lens part of a CCD camera 2 and the adjusting mechanism is controlled by an opening controller 7. Light radiated from a piece of rolled steel P is received by the image pickup element of the camera 2 through a diaphragm and lens in the unit 3. The radiant exitance of the steel P and irradiance on the surface of the image pickup element change in accordance with the temperature T of the steel P. When the camera 2 is made to cope with the variation of the radiant exitance, namely, the variation of the temperature T by adjusting the opening F of the lens, the output V of each pixel of the camera 2 can be maintained at an appropriate value. When the appropriate value of the output V is, for example, about 500mV, the opening can be adjusted to F22 when the temperature T is 1,000 deg.C. In the above-mentioned example, the light receiving time is considered to be fixed.
