Abstract: PURPOSE:To measure only a Cr amount which is related to a compensating effect, by a method wherein a GaAs crystal is irradiated with exciting light to detect strength of a wave length of 1.4-1.7mum out of photo luminescence generated thereupon. CONSTITUTION:A substrate 1 to be measured consisting of a semi-insulating GaAs crystal is secured to a moving stage 2, and is housed in a cryostat device 3 to keep it at 77 deg.K. Through irradiation of the substrate 1 with Ar laser light L, a photo luminescence P is radiated. A lens 4 collects the P and a detector 6 converts it into an electric signal after causing it to pass through a spectroscope. The transmission wave length of the spectroscope is set to about 1.5mum. After the obtained electric signal is freed from noise by a filter circuit 7, it is inputted to a Y-axis of an X-Y recorder 8. Meanwhile, a moving distance of a stage 2 is inputted to the X-axis of the X-Y recorder from a drive gear 9 for moving the stage 2. This permits recording of a relative fluctuation distribution of photo luminescence with a wave length band of 1.5mum and enables finding of a distributing condition of an effective Cr amount in the semiconductor GaAs substrate.

Then, stretched material is cut by an upper cutting edge 5a of a die 5 and a lower cutting edge 3a of the punch 3 to trim the work 4. At this time, tension of the edge of the work 4 is released and the material is restored. The cut end face is drawn to the punch 3 side to some degree and a clearance delta is formed between the cut end face and upper cutting edge. Consequently, friction between the cut end face and upper cutting edge 5a at the time of ascent of the ram 1 can be prevented.

Abstract: PURPOSE:To enable smooth support of both the thrust and radial loads with dynamic pressure by using a simple constitution for making the first and second sets of grooves, which incline in the axial direction but in mutually opposite directions such that they have nearly equal spans but different densities or depths. CONSTITUTION:Dynamic pressure grooves 14, engraved on the surface of a rotary shaft 11 or on the inner surface of a journal 12, are formed with the first and second sets of grooves 14a and 14b which incline to the rotary shaft 11 but in mutually opposite directions.
