Title: Production of alumina fiber
Inventor: SUZUKI TOSHIO
IPC: D01F9/10
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To easily obtain alumina fiber in high spinnability by using a spinning dope prepared by hydrolysis of a mixture of an aluminum alkoxide, an alkanolamine, a magnesium compound and an organic solvent. SOLUTION: First, a spinning dope is prepared by the following process: an aluminum alkoxide such as aluminum isopropoxide is thoroughly mixed with an organic solvent such as isopropanol under agitation followed by incorporating the mixture with an alkanolamine compound such as triethanolamine and a magnesium compound such as magnesium nitrate to form an aluminum alkoxide-contg. solution followed by adding water to the solution and then conducting a hydrolysis in an nitrogen atmosphere. Subsequently, the spinning dope is delivered through a specified spinneret into air, and treated under heating in a steam atmosphere to form a precursor fiber, which, in turn, is baked to obtain the objective γ-phase crystalline alumina fiber.

Title: Formation of aluminum nitride layer
Inventor: ITOU JIYUNKO
IPC: C23C14/06
Filed: 1988-08-31
Abstract: PURPOSE:To form the title dense, thin, and uniform AlN layer at a low cost by providing a C coating layer on the Al2O3 layer on the surface of a substrate, and allowing the Al2O3 to react with N by physical vapor growth method. CONSTITUTION:An Al2O3 layer is formed at least on the surface of a substrate. A C coating layer is formed on the upper surface of the Al2O3 layer, or the powdery grains constituting the Al2O3 layer are coated with C. The Al2O3 on the substrate is allowed to react with N in the presence of C by physical vapor growth method such as ion implantation, AlN is formed by the reaction, and the isolated O ion reacts with C to form CO which is discharged to the outside of the system. The C coating layer remaining after the reaction can be easily removed by heat-treating the substrate at about 600 deg.C. By this method, a dense and uniform AlN layer free of impurities is easily formed.

Title: Ferroelectric liquid crystal display element
Inventor: KOBAYASHI SHUNSUKE
IPC: G02F1/133
Filed: 1991-08-28
Abstract: PURPOSE:To obtain a stable memory characteristic and responsiveness by constituting oriented layers holding a liquid crystal layer of inorg. oriented films obtd. by diagonal vapor deposition of inorg. matter having a prescribed dielectric constant, such as aluminum nitride. CONSTITUTION:The oriented films 2, 2' are constituted of the inorg. oriented films obtd. by the diagonal vapor deposition of the inorg. matter having 7 to 15, more preferably 8 to 10 dielectric constant. Namely, a degradation in the memory characteristic of the liquid crystal, a malfunction, etc., arise if the dielectric constant of the inorg. matter constituting the oriented films 2, 2' is smaller than 7. A short circuiting arises between the oriented films 2 and 2' facing each other on both sides of the liquid crystal at the time of voltage impression if the dielectric constant is larger than 15. Not only the driving of the liquid crystal is then affected but also a failure in driving equipment is resulted. Then, the good memory characteristic is obtd. by constituting the oriented films 2, 2' of the inorg. oriented films obtd. by the diagonal vapor deposition of the inorg. matter having 7 to 15 dielectric constant at 1MHz. In addition, the malfunctions are eliminated and the excellent characteristics to exhibit the good responsiveness are obtd.

Title: Nondirectional clutch device
Inventor: KIMURA AKIYUKI
IPC: F16H35/00
Filed: 1987-08-31
Abstract: PURPOSE:To prevent the sudden rotation of a manual rotor from occurring by installing a drive shaft connected to load, the manual rotor pivotally installed in this drive shaft free of racing, a handle attached to a turning end of this manual rotor free of racing, and a differential transmission mechanism installed among this handle, the manual rotor and the drive shaft. CONSTITUTION:When manual operation is not yet carried out, a handle 4 is made to be free of racing to a manual operator 3. Consequently, even if load 1 is driven by an electric motor 12, by way of example, and thereby reverse driving force acts on a drive shaft 2 from the side of the load 1, the manual operator 3 is in no case rotated with the substantial driving force. That is to say, rotation of the drive shaft is differentially distributed to the manual operator 3 and the handle 4 via a differential transmission mechanism 5, but the handle 4 is in a no-load state if it overrides the frictional resistance of each part, whereas the manual operator 3 comes into contact with an elastic piece 6 and is given some rotational resistance. Consequently, when the drive shaft 2 is rotated, the handle 4 races, and the manual operator 3 comes to be held at a specified position contacting with the elastic piece 6 in consequence.

Title: Heat sink for array semiconductor laser
Inventor: OTA YOSHINORI
IPC: H01L23/36
Filed: 1986-09-16
Abstract: PURPOSE:To conduct isolation in response to a layer element, and to enable high density packaging by forming the width of a cross section in size wider at the position of substrate depth than the position of a fusing surface in the sectional form of a trench along the direction of resonance of a semiconductor laser formed onto an silicon substrate surface to which the array semiconductor laser is fused. CONSTITUTION:An Si crystal layer 2 containing B can be shaped as a crystal layer through an epitaxial growth method. The layer 2 containing B is etched to a trench shape, using KOH as an etchant by employing a mask using a photo-resist. When the mixed liquid of ethylene diamine and pyrocatechol is heated at the boiling point of 116 deg.C and the Si substrate 1 is dipped into the mixed liquid, Si 1 is etched to a cellar shape that the layer 2 containing B is formed as eaves because the layer 2 has an extremely slow etching rate, and a trench 6 having narrow width in a fusing section with a laser and broad width in a deep section is shaped. When Sn 4 is evaporated, Sn does not adhere on the side walls of each trench 6, and only collects as Sn 5 on the bottoms of the trenches 6. Accordingly, electrodes 3a, 3b, 3c are not conducted, thus independently driving respective laser element.
