Title: Manufacture of stainless steel clad steel plate
Inventor: WAKI TAKANOBU
IPC: B23K20/04
Filed: 1981-11-19
Abstract: PURPOSE:To obtain a titled steel plate which is good in its workability and is high in  its quality, by fixing an Ni plate to a base material, in a manufacturing method by  which cladding by welding is executed by placing Ni on the base material, and after that, hot rolling is executed. CONSTITUTION:The surface of a base material 2 such as a slab or an ingot, etc. is  subjected to cut-working and descaling, its surface state is smoothed and cleaned, and  after that, an Ni plate 4 having the almost same area as the base material 2 and  suitable thickness is superposed and fixed on the base material. When fixing it, spot welding of the plate 4 and the base material 2 is optimum, and as for an interval (h)  of a welding break point 5, its size can be decided by size of thickness of the plate 4,  and as for the thickness of the plate 4, 1.0-1.5mm. or so is optimum. In this way, from  the upper surface of the plate 4, cladding by welding of stainless steel is executed by  plasma arc welding, etc. In this case, a method for melting only the plate 4 is desirable, and a wall protecting effect of C in the base material is sufficient by the thickness  of said plate 4. Even if both the plate 4 and the base material 2 are melted, C in the  base material is diluted by Ni owing to existence of Ni. Accordingly, a quality of the  cladding by welding part becomes satisfactory, and a clad steel plate having a high  quality is obtained.

Title: Optical waveguide
Inventor: IWASAKI MASAAKI
IPC: G02B6/122
Filed: 1989-07-18
Abstract: PURPOSE:To obtain an optical waveguide which decreases the dependency of the loss on polarized light by subjecting the adjacent part along the curve part of the optical waveguide to an ion exchange from the surface of a substrate. CONSTITUTION:The Ti-diffused curve waveguide 2 and the ion exchange layer (proton exchange layer) 3 consisting of proton are formed on the substrate 1 consisting of a lithium niobate crystal (LiNbO3) having the Z-axis perpendicular to the substrate surface. Namely, the refractive index n0 to extraordinary light increases in the section subjected to the ion exchange in the case of the crystal, such as lithium niobate or lithium tantalate, having optical anisotropy. The confinement of light is, therefore, intensified in a TE mode and is weakened in a TM mode. The difference in the radiation loss between the TE mode and the TM mode is decreased. The dependency of the loss of the optical waveguide on the polarized light is decreased in this way.

Title: Inner resonance surface light emitting shg laser
Inventor: ITOU AKITOMO
IPC: H01S5/06
Filed: 1994-08-09
Abstract: PURPOSE:To obtain sharp and high efficiency by irradiating reflection light on a surface light emitting semiconductor laser and integrating multilayer films generating second harmonic wave light between two mirrors arranged to sandwich the laser. CONSTITUTION:When a current is injected into an electrode 7, laser oscillation is generated on the laser part 4 consisting of an MQW layer of ZnSSe/ZnCdSe. At this time, when a reflection factor of a multilayer film reflection mirror 2 of a dielectric and a multilayer film mirror 5 of a p-type ZnSe/ ZnSSe is made to have a high reflection factor (not less than about 99.9%) in a laser oscillation wavelength, a fundamental wave is confined inside a resonator formed by these mirror so as to have extremely high photopower density inside the resonator. Thereby, a short wavelength coherent light source is realized over an ultraviolet ray of a wavelength 250nm range and a visible violet ray of a wavelength 400nm, which is hard to oscillate by a normal semiconductor laser.

Title: Method of processing diamond grain
Inventor: DEIITORITSUHI BORUZE
IPC: C04B41/53
Filed: 1987-07-29
Abstract: For the use of diamond particles as a component part of machining tools or other tools, it is customary to hold the diamond particles in a bond, in particular a metallic bond. Retention is increased in this case if the diamond particles have a roughened surface. This can take place by etching. In the case of the known methods for processing the surface of the diamonds, they are, however, partially destroyed if processing takes place at high temperatures, that is to say in excess of 1000 DEG C, or there is a great loss of diamond material. This is overcome if, to increase their surface area to at least twice the size of their natural surface area by making pores in them, the diamond particles (1) are embedded in a metal powder and subjected to a stream of hydrogen or a hydrogen-containing gas at a temperature above 700 DEG C. Thereafter, the diamond particles (1) can be cleaned with an acid. Iron, cobalt, nickel or an alloy of these metals come into consideration as metal powder.
