Title: Production of single crystal
Inventor: ECHIZENYA KAZUHIKO
IPC: C30B15/20
Filed: 1987-11-11
Abstract: PURPOSE:To form the shape of a crown to a good shape with good controllability by dividing the conditions for growing the crown part to two stages, then increasing the crystal size in the 1st stage and increasing the crystal diameter to a target diameter in the 2nd stage. CONSTITUTION:The crown shape is controlled by dividing the control to the two stages. The melt temp. is stabilized by gradually lowering said temp. from the adequate temp. at the time of neck growth down to the adequate temp. at the time of body growth to gradually increase the crystal diameter in the 1st stage 1. The pulling-up speed is fluctuated in the stabilized state of the melt temp. to increase the diameter of the crown to the target diameter in the 2nd stage 2. The control loop to previously set the target diameter and to control the pulling-up speed while comparing the same with preferably the measured value by a diameter sensor is preferably incorporated. The good crown shape is thereby formed with the good controllability and the number of the stacking faults to be generated is decreased. The yield is thus improved.

IPC: H01J35/10
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To decrease the wear of bearing portions of a rotary anode X-ray tube by adding solids having low sliding friction to a lubricant which is made to exist in the bearing portions. SOLUTION: In a rotation anode X-ray tube, a gap between a bearing shaft 8 and a bearing outer plate 9 is preferably filled with a liquid lubricant of a gallium alloy in the region of groove pattern 11 provided at least on a bearing surface.

Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To remove the asymmetry of expansion and astigmatism, which a semiconductor laser emitting beam has, by arranging a cylindrical lens in connection to or closely to a beam emitting end face. SOLUTION: The cylindrical lens 2 is placed closely to the emitting face of a laser chip 1. A ball lens 3 is to converge laser light to a point image. The height expansion angle of the beam emitted from the semiconductor laser is reduced by curvature which the cylindrical lens 2 has and the expansion angle is enlarged by emission from a high refractive index medium (lens) to a low refractive index medium (air).

The ball lens 3 is operates as a collimator lens and a focus lens.  The point image of the focus point forms laser light to be circular and it is set to be the image converged to a micro part having a uniform brightness.
