  • Deformable mirror and method for fabricating the same and apparatus using a deformable mirror
    Patent number: 5719846
    Abstract: A deformable mirror for reflecting a light beam incident thereon of the present invention includes: a flexible member which has a reflective surface and is flexibly deformable; a substrate having a reference surface which faces the flexible member; and a driving section for making the flexible member adhere to the reference surface of the substrate, thereby deforming the reflective surface of the flexible member to correspond to the reference surface. The shape of the reference surface is designed in such a manner that the light beam is provided with a spherical aberration when the reflective surface adheres to the reference surface.

  • Mold casting process and apparatus and method for producing mechanical parts
    Patent number: 5263532
    Abstract: A mold casting process comprises, after pouring of a molten metal into a mold, rapidly cooling that surface layer of a cast product which is in contact with a mold, and releasing the resulting product from the mold when the surface layer thereof has been converted into a shell-like solidified layer. Such process is used for casting a mechanical part blank and apparatus for carrying out the process is provided.

  • Process for producing silicon carbide sintered product
    Patent number: 4737327
    Abstract: A process for producing a silicon carbide sintered product, particularly, large-shaped silicon carbide sintered product by reaction sintering. Siliciding reaction can be carried out completely in a short period of time by adding an organic silicon polymer whose skelton is composed of silicon and carbon to the starting sintering material and using the same for the control of the reaction rate.
