Title: Method of connecting revolving shaft
Inventor: IDETA MITSUGI
IPC: F16D1/06
Filed: 1986-04-21
Abstract: PURPOSE:To eliminate the play in the direction of revolution, by manufacturing one of a revolving shaft and a body of revolution by means of a hard metal material and manufacturing the other by means of a soft metal material and swelling out a part of the soft-metal-material-side spline through the quenching treatment, so that the above two are engaged by pressure with each other when they are connected. CONSTITUTION:A body of revolution 2 is formed with the steel material that did not take the hardening treatment through quenching, while an inner spline 3 having a predetermined shape is formed on the shaft core part. In addition, the entire inner surface of the opening-peripheral-part 16 on the surface side of the inner spline 3 is treated by induction hardening, thereby swelling out the part of the inner spline 3 toward the center of the spline 3 and thereby slightly narrowing the tooth-to-tooth interval. On the other hand, after an outer spline is formed on the revolving shaft, the entire surfaces of both undergo the hardening treatment. When both revolving shaft and body of revolution 2 are connected, the outer spline of the revolving shaft is pushed by pressure into the swollen part of the inner spline 3. Accordingly, the play in the connecting part can be eliminated, thereby ensuring the smooth transmission of rotational torque.

Filed: 1987-04-13
Abstract: PURPOSE:To realize the stabilized leveling calibration with high speed, by inclining the projection image itself of a mask pattern so as to match the inclination of a photosensitive substrate surface. CONSTITUTION:A mask retaining member RH is provided, which can hold a mask (reticle) R with an inclination angle in an arbitray direction. The inclination of the mask retaining member RH is so controlled that the relative inclination amount between a specified region (shot region) surface on a photosensitive substrate W and the projection image surface of the pattern of the mask R can be calibrated so as to be approximately zero. When the surface of a projection region on the photosensitive substrate W undulates or inclines with a not allowable degree from a viewpoint of the focal depth and the curvature of field, the mask (reticle) R side is made to incline by the amount corresponding with the surface inclination. Thereby, the stabilized leveling calibration with high speed for each shot region is enabled.
