Title: Apparatus for drawing optical fiber preform
Inventor: HIRAMOTO YOSHIYUKI
IPC: C03B37/029
Filed: 1988-06-24
Abstract: PURPOSE:To prevent the deposition of foreign material originated from a furnace core tube material on a preform during the drawing of a preform in a furnace core tube by inserting an upper and a lower quartz tubes concentrically into a furnace core tube and passing an inert gas between the quartz tube and the furnace core tube. CONSTITUTION:A quartz tube 2 is concentrically inserted into a carbon furnace core tube forming a gap of about 5mm along the inner wall of the furnace core tube 3 of a heating apparatus. The quartz tube 2 is divided into the upper section and the lower section to form a slit between both sections. An optical fiber preform 1 is inserted into the furnace of the heating furnace and an inert gas is passed through the gap between the inner wall of the furnace core tube 3 and the quartz tube 2 and blasted into the furnace through the slit between the sections. The preform 1 is heated with a carbon heater 4 through the furnace core tube 3 to effect the melting and drawing of the preform. The outer circumference of the preform 1 at the drawing part is maintained in an inert atmosphere together with the inner wall of the furnace core tube 3. Accordingly, the oxidation of the carbon material can be prevented to keep the preform 1 from the deposition of oxidized carbon fine particles.

Title: Nonlinear optical element and working method thereof
Inventor: KOUDA HIKARI
IPC: G02B1/14
Filed: 1991-05-31
Abstract: PURPOSE:To easily form a surface protective film which prevents the loss of clarity without using a material exclusive of crystals by subjecting the mirror- polished surface of the element to a heating treatment with a laser beam. CONSTITUTION:The surface part of the mirror-polished surface of the nonlinear optical element formed by using a nonlinear optical single crystal having hygroscopicity is subjected to the heating treatment with the laser beam, by which the protective film solidified after melting is formed. Namely, the mirror- polished extreme surface of the element formed by using the optical crystal having the hygroscopicity is increased in chemical reactivity by the disturbance in atomic configuration. This surface reacts immediately with the steam in air and loses the clarity as the hydrate sticks to the surface. The surface is, however, instantaneously heated by the laser beam, by which the extreme surface part is melted and the thin film is formed on the polished surface. Such surface does not react with the steam in the air any more.

Title: Substrate heater
Inventor: MATSUSHITA MASANAO
IPC: H01L21/027
Filed: 1995-06-22
Abstract: PURPOSE: To provide a substrate heater which can avoid inhomogeneous thermal treatment of a substrate caused by ambient air introduced when the substrate is fed into the substrate heater. CONSTITUTION: A wafer (W) is fed into a casing (20) and then placed on a plate (40). Subsequently, a cover (60) is moved down to thermally treat the wafer (W) placed on the plate (40) in a semi-sealed space defined by the plate (40) and cover (60). The wafer (W), when being fed into or out from the heater, is subjected to an inhomogeneous temperature distribution under the influence of ambient air invaded from the side of a shutter (20a). However, since a substrate introduction part (30a) is disposed between the shutter (20a) and a substrate processor (30b), the temperature of the substrate processor (30b) where the wafer (W) is placed in the depth of the casing can be kept substantially constant.  Thereby the wafer (W) can receive a homogenous amount of heat from the ambient plate (40) and cover (60) from the beginning of thermal treatment of the respective parts of the wafer (W), whereby the wafer (W) can be subjected to a homogeneous thermal treatment.
