Title: Hetero junction field effect transistor
Inventor: HARA NAOKI
IPC: H01L21/338
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent oxidation of a lower Schottky contact layer by arranging an upper Schottky contact layer of small Al composition ratio on the lower Schottky contact layer and forming a gate electrode on the upper Schottky contact layer. SOLUTION: Schottky contact layers 4, 5 consisting of AlGaAs are inserted between a channel layer 3 and a gate electrode 7. Al composition ratio of the upper Schottky contact layer 5 is 0.3 and Al composition ratio of the lower Schottky contact layer 4 is 0.8. A large gate-to-source forward breakdown strength can be obtained by the lower Scohttky contact layer 4 of large Al composition ratio. Al composition ratio of the upper schottky contact layer 5 arranged below a cap layer 6 is 0.3. Since the lower Scohttky contact layer 4 of large Al composition ratio is not thereby exposed to a groove 9 during treatment by ammonium-based etchant after formation of the groove 9 by etching the cap layer 6, oxidation of a lower Schottky contact layer can be prevented.

Title: Optical recording member
Inventor: TAKEI TOSHIJI
IPC: G11B7/24
Filed: 1987-03-03
Abstract: PURPOSE:To obtain a member which quadruples the density of a recording surface and contributes to the reduction in the cost of an optical pickup and the enhancement of the performance thereof by using a nonlinear optical material for an intermediate layer between a recording layer and substrate of an optical recording member and converting the wavelength of a light source for optical recording to a half wavelength. CONSTITUTION:The nonlinear optical material 11 and the recording layer 2 are successively laminated on the substrate 1 and are covered by a protective cover 5. Light of a wavelength past the substrate 1 is made into the light of lambda/2 wavelength by the effect of the material 11 and arrives at the recording layer 2. In general, the efficiency of a nonlinear effect is small but the just before arriving at the recording layer 2 past an objective lens has sufficient photon density. The nonlinear effect, therefore, increases sufficiently and second order higher harmonics can be generated. Since the recording layer 2 is subjected to the recording by the light of lambda/2 the wavelength in such a manner, the spot size is made into 0.5mum and the density of the recording surface is quadrupled. Reduction of NA of the objective lens to a half is also possible. The high-performance optical pickup is obtd. at a lower cost.

Filed: 1986-03-07
Abstract: PURPOSE:To improve a soldering quality by providing the filament luminous source in a finite length and a parabolic reflection mirror and by arranging the spherical lens to collect the reflected light and a cylindrical lens. CONSTITUTION:The parabolic reflection mirror 15 which can detect maximum the light emitted from the coil-like filament 14 in a finite length is arranged and a diaphragm body 11 is arranged just before a field lens 9 as well. The light emitted from the filament 14 is reflected by a reflection mirror 15 to become a parallel light, reducing the solid angle of the light reaching the diaphragm body 11 by being refracted with a condensing lens 16. A rectangular focusing image 10 is then formed by the cylindrical lens 3 by making the majority of the reflected light incident on the lens 9 by the disphragm body 11. In this case, the energy density of the focuses image 10 is increased and the soldering of high density due to the heating in a small range is enabled as well. The soldering quality is therefore improved.

Abstract: A method for manufacturing a glass core rod and a cladding layer clothing the glass core rod applied successively or continuously by using a carbon dioxide gas laser. A refractory mandrel is heated by means of carbon dioxide gas laser irradiation and a mixed gas of oxygen and pure silicon tetrachloride vapor and a dopant compound vapor is ejected to the refractory mandrel so as to deposit silicon oxide and oxide of the dopant compound on the mandrel and to form a glass core by fusing it. Further heating is applied by irradiation by the carbon dioxide laser beam on the glass core and a mixed gas oxygen and pure silicon tetrachloride vapor and a dopant compound vapor or of oxygen gas and pure silicon tetrachloride vapor to deposit silicon oxide and oxide of the dopant compound or silicon oxide on the glass core to form a cladding layer of fused silica or fused silica containing the dopant. The preform thus formed by the glass core and the cladding is heated above the softening temperature of the preform so as to spin to form an optical fibre. The method uses laser beam heating which results in less degree of contaminating impurity and water content which might cause absorption and scattering of light also to manufacture an optical fiber having less variation at the boundary of the glass core and the cladding layer.
