Title: Focusing
Inventor: YOSHIZAWA MASAHIRO
IPC: H01J37/21
Filed: 1988-11-21
Abstract: PURPOSE:To improve precision of focusing setting by taking a two-dimensional image by changing focusing distances, projecting and adding a signal in the X, Y directions of this image to obtain a one-dimensional wave form, and focusing in such a way that the inclination of this waveform becomes the sharpest. CONSTITUTION:Two-dimensional scan is performed for one focusing distance, each signal wave form is added in the Y-axis direction parallel to a pattern, a one-dimensional projection wave form in the X-direction crossing the pattern is determined and its inclination is detected, these actions are repeated in order for different focusing distances, and the focusing distance at which the inclination is the sharpest is calculated. This means that one-dimensional wave form for one focusing distance is obtained by producing (adding) a two-dimensional image in one direction, so the inclination of the wave form can be detected at a high precision by one take of the image. Focusing can thus be achieved regardless of an edge position if the pattern is not at the center, and the precision of setting can be improved.

A thread connection part 30 is formed between the thread stem part 10 and the thread guide part 20. When, by forming a tapping screw wherein a relief groove 4 is formed at least in the thread stem part 10, the tapping screw is screwed in a screw hole of a soft metallic material, since the female screw does not make contact with the whole of the screw, fastening torque is lowered.  Further, since the generation of a friction heat is reduced between the tapping screw and the female screw, adhesion is prevented from occurring to a thread surface. Since, when an axial force is added, the thick wall of the female screw is fitted in the relief groove, the screw is prevented from being unfastened from a work on which vibration is exerted.

Title: Iridium-added nickel-base superalloy
Inventor: KOBAYASHI TOSHIHARU
IPC: C22C19/03
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To provide an alloy having excellent high temp. strength and high temp. corrosion resistance by adding specific amounts of iridium to an Ni-base superarlloy. SOLUTION: The additive quantity of iridium is regulated to 0.1-5 atomic %. By the addition of Ir, an alloy structure is aligned and the stability of the structure is superiority maintained, and further, precipitation strengthening is allowed to proceed, and simultaneously, Ir is allowed to enter into solid solution in γ-phases and γ'-phases and solid solution strengthening is allowed to proceed. Because Ir has a face-centered cubic structure identical with that of Ni, it can be easily replaced with Ni. Accordingly, the above Ir-added Ni-base superalloy has excellent high temp. strength and can withstand use under high temp. and high stress. Further, because Ir has a high melting point and has low diffusion coefficient even at high temp., deterioration in the properties of the Ni-base superalloy can be prevented and also high temp. corrosion resistance can be improved.  As to the additive quantity of Ir, >=0.1 atomic % is necessary to sufficiently improve high temp. strength and high temp. corrosion resistance, and on the other hand, when the additive quantity of Ir exceeds 5 atomic %, specific gravity is increased and an influence is produced on price.
