Title: Optical three-dimensional shape measuring instrument
Inventor: HORI KENJI
IPC: G01B11/24
Filed: 1994-09-29
Abstract: PURPOSE: To quickly measure the shape of a three-dimensional surface over a wide extent with high accuracy by commonly using an objective optical system between an irradiation optical system and observation optical system and independently specifying respective optical paths by providing an aperture stop as the wave surface dividing means of the pupil surface of the objective optical system. CONSTITUTION: The light from a stroboscopic light source 31 forms a prescribed irradiation pattern after passing through a pattern, plate 32 and reflected downward by one inclined surface 33a of a truncated hexagonal pyramid-like prism 33. The reflected light passes through the opening 34a of an aperture stop 34 and forms a projected pattern on the surface of an object 36 to be inspected through a common objective optical system 35. On the other hand, the light from the projected pattern image formed on the surface of the object 36 is reflected in the horizontal direction by another inclined surface 33b of the prism 33 after passing through the optical system 35 and opening 34a and made incident on such an observing surface 37 as the CCD.  Since the irradiation optical system and observing optical system commonly use the optical system 35 and optical paths 38 and 39 are independently controlled by means of the aperture stop 34 in such a way, the pattern can be made finer and high-resolution measurement can be performed by using the optical system 35 having a short working distance, namely, a large numerical aperture.

Title: Induction suppression system for external wave
Inventor: HASHIMOTO MAKOTO
IPC: H04M19/00
Filed: 1984-12-10
Abstract: PURPOSE:To suppress an in-phase signal in a high frequency range which is induced with an external wave such as an AM wave, etc., by providing a conventional in-phase mode impedance suppressing circuit with a circuit which corrects its operation only in the high frequency range, and compensating a decrease in the gain of a feedback circuit due to restrictions of gain band width, etc., in the high frequency range. CONSTITUTION:A filter 28 which passes signals of frequency in a broadcasting band is added to the conventional in-phase mode impedance suppressing circuit. Input signals of frequency which are not within the broadcasting wave band (e.g. audio band) are cut off the filter 28 and a current amplifier 29 does not operate. The current amplifier 29, on the other hand, operates for frequencies in the broadcasting wave band similarly to a current amplifier 4. (The input part of the filter 28 has high impedance and does not exert any influence upon the input signal of the current amplifier 4.) Consequently, even if the current amplifiers 4 and 29 decrease in gain in the broadcasting wave owing to restrictions of gain band width, etc., the quantity of feedback which is at least twice as large as before is obtained. Namely, the in-phase mode impedance in this band is reduced to at east a half as large as before.

Title: Production of optical recording medium
Inventor: NAGAI SATOSHI
IPC: G11B7/26
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To improve the adhesiveness of a thin film and to obtain an optical recording medium having superior repetitive characteristics by feeding a molded substrate at a prescribed temp. into a sputtering device and forming the thin film on the substrate by sputtering. SOLUTION: When an optical recording medium is produced, a molded substrate is fed at 40-130 deg.C into a sputtering device and a thin film layer is formed on the substrate by sputtering. In the case of <40 deg.C, an effect of improving film forming property by sputtering is hardly expected and a significant effect of improving the repetitive characteristics of the resultant optical recording medium is hardly produced. In the case of >130 deg.C, especially a high temp. of >=140 deg.C, the substrate is liable to deformation during handling. The molded substrate is therefore fed at 40-130 deg.C, preferably 40-100 deg.C, especially preferably 50-80 deg.C. A process for cooling a substrate after molding can be omitted and the production cost can be reduced.

Title: Method and apparatus for measuring eccentricity of aspherical lens
Inventor: MORITA NOBUHIRO
IPC: G01B11/27
Filed: 1993-10-18
Abstract: PURPOSE:To provide an apparatus, which measures the eccentricity of an aspherical lens. CONSTITUTION:A holding means 2 holding a lens under inspection 1 is rotated with a driving means 3. The light from a light source 5 is reflected from the lens under inspection 1, and the spot image is focused on a spot-position detecting means 8 with an optical system 7. When the optical axis of the lens under inspection and the rotating axis do not agree, the spot image draws a circle on the image forming plane by the rotation of the lens under inspection. Meanwhile, a displacement measuring means 9 measures the deviation of an aspherical surface 1b in the direction of the optical axis caused by the rotation. The deviation between the optical axis and the rotating axis and the direction of the deviation are obtained based on the circle drawn by the spot image. The deviation of the aspheric surface in the direction of the optical. surface is obtained based on these values. The deviation is subtracted from the actually measured value obtained with the displacement measuring means 9. Thus, the deviation between the optical axis of the lens under inspection and the axis of the aspherical surface, i.e., the eccentricity, is obtained. The measurement can be performed without correcting the setting of the lens under inspection.

Title: Manufacture of superconductor device
Inventor: ISHIMARU YOSHIYASU
IPC: H01L39/24
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent surface flatness by preparing a laminated substrate made by forming an oxide superconductor film having a specified thickness or above on an insulator substrate by a liquid phase epitaxial method, and then mechanically polishing the oxide superconductor film on a rotating polishing disc using a specified polishing liquid. SOLUTION: An MgO substrate 15 is brought into contact with the surface of a YBCO melted liquid in a crucible 11 and is gradually pulled up while being turned, to form a YBCO film (oxide superconductor film) 16 of the thickness of 1 μm or above on the surface of the MgO substrate 15. The YBCO film 16 having an unevenness formed on the surface of the MgO substrate 15 is mechanically polished by a grinding disc 25 to be flattened. Since the YBCO film 16 deteriorates in its characteristics when it is brought into contact with water, use of water should be avoided. Therefore, a liquid containing no water dispersed with polishing grains having the average grain diameter of 0.05 μm or below is used for a polishing liquid. For example, an oil slurry made by dispersing alumina grains in hydrocarbon-system oil mainly of petroleum naphtha is used.
