Title: Manufacture of reduction reoxidation type semiconductor porcelain element
Inventor: NOI KEIICHI
IPC: H01C7/10
Filed: 1988-08-24
Abstract: PURPOSE:To suppress the generation of a high resistance oxide layer on one side surface of an element and to facilitate a mass production by molding and reducing a reduction reoxidation type semiconductor porcelain material as a main component, and burying the one side surface of the element in substance having slower diffusion of oxygen than that of the main component to reoxidize it. CONSTITUTION:Specific amounts of SrTiO3, Nb2O5, CuO are molded in a disc state. Then, after it is fired in the air, it is baked in a reducing atmosphere. Subsequently, MgO powder is laid in a magnetic sheath, reduced and fired discs are so aligned thereon with one side faces disposed down that the faces are completely buried in the powder, and heat treated in the air to be reoxidized. Then, the opposed faces of the discs are coated with electrode pastes such as Ag, and mins-fired in the air to form electrodes. The diffusion of oxygen is delayed from the main component so that the oxygen is scarcely diffused to the surface of a semiconductor porcelain in contact with the MgO in the MgO and a high resistance layer is hardly formed. Accordingly, electrostatic capacity is remarkably increased as compared with the case that high resistance oxide layers are provided on both side surfaces of the element.

Title: Laser beam machining device
Inventor: AOKI HIKOHARU
IPC: B23K26/00
Filed: 1994-09-05
Abstract: PURPOSE: To restrict the dimensional change in a laser beam so as to reach an aperture member over a long time by installing a reducing member on an oscillator and making the size of the laser beam arrived onto the aperture member smaller than the size of the laser beam just after it is oscillated. CONSTITUTION: For an excimer laser beam 2 emitted from an oscillator 1, an optical path reaching a machining table 8 is prepared with mirrors 3a to 3c. This oscillator 1 has a total reflection mirror 22 having curvature on the reflecting face and a partial transmission mirror 22 not having curvature on the reflecting face. The excimer laser beam 2 emitted from the partial transemission mirror 20 has the tendency of being converged. That is, the irradiation area of the excimer laser beam 2 reaching an aperture member 11 is smaller than the irradiation area of the excimer laser beam 2 just after it is emitted from the partial transmission mirror 20. Therefore, the enlargement of the beam spreading angle can be restricted, so that the excimer laser beam 2 being cut with the aperture member 11 is not almost changed even for a long time of operation.
