Abstract: PROBLEM TO BE SOLVED: To obtain a surface treated steel excellent in corrosion resistance by irradiating light to the coating having a two layer structure in which, after formation of an oxide coating layer contg. zinc oxide as a lower layer on the surface of a steel, coating contg. titanium oxide is formed as an upper layer with light. SOLUTION: This surface treated steel is the one in which the surface of a steel is applied with a primary coating layer contg. zinc oxide by 12 to 100wt.% in the solid content in the coating as a lower layer, and it surface is applied with a secondary coating layer contg. 15 to 100wt.% titanium oxide. This coating having a two layer structure is irradiated with light. In the case the content of zinc oxide in the lower layer coating is less than 12%, the effect of improving its corrosion resistance is low. As for the method for forming the lower layer coating, there is no limitation in particular, and, e.g. zinc oxide may be adhered thereto by an electrolytic method or the galvanized steel may be subjected to oxidizing treatment or electrolytic treatment.  In the case the content of titanium oxide in the secondary coating layer is less than the lower limit, the effect of improving its anticorrosive properties is low. As for the method for forming the secondary coating, there is no prescription, and, e.g. a PVD method, a CVD method or the like may be adopted.

Abstract: PURPOSE:To suppress the flapping phenomenon of the frequency characteristic of a reproducing output by a contour effect by forming high temperature superconductive members between a metal magnetic member and a high magnetic permeability ferrite so as to oppose in parallel to an operating gap and through the operating gap. CONSTITUTION:The high temperature superconductive member 4a is formed physically or according to a method such as a sputtering in the boundary part of the metal magnetic film 1c and the high magnetic permeability ferrite 1a so as to oppose in parallel to the operating gap 1b and through the operating gap 1c. When a recording current is passed to a coil 1f, a magnetic flux is generated in the high magnetic permeability ferrite 1a and the magnetic flux is converged to the operating gap 1b by a magnetic circuit to record. According to the Meissner effect by the high temperature superconductive member 4a formed in the boundary part of the metal magnetic film 1c and the high magnetic permeability ferrite 1a, the magnetic flux is not leaked in the direction of a recording medium, so that a pseudo gap does not effectively depend. The flapping phenomenon of the frequency characteristic of the reproducing output is eliminated.

Abstract: PURPOSE: To provide an optical fiber gyroscope in which a phase control can be precisely performed even when the value of an input angle speed is small. CONSTITUTION: A first phase difference Δβ and a second phase difference σare generated in a signal having an interference light intensity I by a phase controller. The first phase difference Δβ is alternately changed to a first operating point ΔβA=-(2n-1)π/2 and a second operating point Δβ=+(2n-1)π/2, whereby the difference ΔI between the signal I=IA in the first operating point ΔβA and the signal I=IB in the second operating point ΔβB is provided as a signal proportional to sin(Δθ+σ). The second phase difference σ is controlled so that this difference signal ΔI is zero to feed back the phase. At that time, the sum of the two phase differences Δβ+σ forms a saw-tooth serrodyne wave.  The wave numbers NA, NB of the serrodyne wave in the first and second operating points ΔβA, ΔβB are set constant, respectively.

Title: Manufacture of semiconductor device
Inventor: SASAKI TAKAE
IPC: H01L21/20
Filed: 1989-12-18
Abstract: PURPOSE:To obtain a silicon-on-insulator(SIO) substrate which is made of single crystallized silicon layer and has a good crystallinity by converting a polycrystalline silicon layer of large crystal gains converted by heat-treatment into a single crystalline silicon layer by irradiating the polycrystalline silicon layer with an energetic beam. CONSTITUTION:When an amorphous silicon layer or an amorphous silicon layer containing silicon crystals is formed on an substrate having an insulating layer on the surface and the layer is heat-treated, the layer is converted to a polycrystalline silicon layer of large crystal grains. When the layer is irradiated with an energetic beam, the polycrystalline silicon layer of large crystal grains is more excellently converted into a single crystalline layer than a polycrystalline silicon layer of small crystal grains which disturb excellent single crystallization. As a result, an SOI substrate for semiconductor which is made of a single crystallized silicon layer and has a good crystallinity is produced in a short time.

Filed: 1987-12-23
Abstract: PURPOSE:To preclude misdetection in a case when a body to be detected enters a proper detection state by making a position decision means decides whether the body to be detected is in the proper detection state to a light beam from a light projecting element. CONSTITUTION:When the body 10 to be detected is positioned in the proper detection state in the light beam outputted by the light projecting element 1, the light beam is reflected by the body 10 and its reflected light beam is photodetected by the position detecting element 4. Then the distance to the body 10 is calculated from its photodetection signal.

In this case, a distance calculation result based upon the output of said position detection element is not outputted.
