Title: Semiconductor substrate
Inventor: KUDO ATSUSHI
IPC: H01L29/20
Filed: 1987-05-25
Abstract: PURPOSE:To improve the mechanical strength and thermal conductivity of a substrate and have a favorable insulation property by forming a single crystal compound semiconductor layer on an insulation layer where a semiconductor substrate consisting of a single element is dielectrically isolated through a semiconductor layer which has the same quality as that of a very thin filmed substrate. CONSTITUTION:After forming an insulating layer 2 consisting of amorphous SiO2 on a silicon substrate 1, an opening 3 for seeding is formed at the prescribed position of the insulating layer 2 with a photolithographical technique by using a resist formed on the insulating layer 2 as a mask. Then, after forming a silicon layer 4 having a 5000 Angstrom  film thickness with a LPCVD technique and the like on the insulating layer 2 including the inside of the opening 3, this layer is crystallized to form a single crystal by a melting recrystallization technique using a laser or an electron beam. And then, the oxidation of a silicon single crystal layer in an atmosphere of dry oxygen at a temperature of 1100 deg.C allows a thermal oxide film 5 to grow about 9500 Angstrom  film thickness at the silicon layer 4 and its film 5 is removed by etching with an etchant of buffer hydrofluoric acid (HF+NH4F) and the silicon layer 4 having the desired very thin film remains on the insulating layer 2. Further, this approach grows compound semiconductors such as GaAs, InP and the like on the very thin filmed silicon layer 4.

Title: Measuring device for deformation rate of continuous casting billet
Inventor: ISHIDA TOSHIAKI
IPC: G01B5/28
Filed: 1983-07-15
Abstract: PURPOSE:To make continuous measurement in short time by providing two vertical arms with measuring rollers which are in contact with the corners of a billet guided by a guide roller in-between and providing two horizontal arms and means for detecting deformation to the top ends thereof. CONSTITUTION:When a rhombic deformation arises to a billet 6 moved under the guide of a guide roller 5, measuring rolers 11a, 11b pressed to the corners in the horizontal direction of the billet 6 displace inward or outward by as much as the distance corresponding to the change in the diagonal size. The top ends of vertical arms 9a, 9b turn largely inward or outward with such displacement and amplify mechanically the displacement of the rollers 11a, 11b. Then horizontal arms 12a, 12b move horizontally and a horizontal displacement arises at the other end of the arms 12a, 12b. The displacement is measured by a gauge 15 and an indicating pointer 17.

Title: Manufacture of steel pipe of high fatigue strength for use in hollow axle
Inventor: KODERA SHUNEI
IPC: B23P9/00
Filed: 1992-04-22
Abstract: PURPOSE:To suitably improve the fatigue strength of a steel pipe for use in hollow axle by grinding-machining the inner face of the steel pipe by 10 to 1200mum. CONSTITUTION:With a steel pipe for use in driving hollow axle, the inner face of the steel pipe is ground and machined by 10mum or more to grind and remove one or two or more of irregularities, flaws or decarburized layer to improve the fatigue strength property. The metal-removal rate is changed depending on the inner bore diameter of the hollow axle. In the case of this type of hollow axle, the upper limit of metal removal rate is 1200mum. The grinding process is relatively simple and low-priced, and the wall-thinning for grinding-machining is limited to maintain the strength property.

Title: Pipe line stirring apparatus
Inventor: KAMODA TAKEMASA
IPC: B01F15/00
Filed: 1985-06-15
Abstract: PURPOSE:To prevent the generation of leakage of a fluid to the outside by providing a rotor fixed and supported onto the stirring shaft, a stator fixed and arranged onto the internal wall surface of the pipe line facing the rotor and a stirring vane mounted onto the stirring shaft. CONSTITUTION:When the load of the fluid to be stirred is increased, the number of revolutions of the stirring apparatus 15 is naturally decreased. The number of revolutions of the stirring apparatus 15 is always detected by a revolution detector, and the number of revolutions is fed-back through a revolution feedback signal converter 16. For this reason, when the number of revolutions of the stirring apparatus 15 is decreased, the power source frequency of an AC power source apparatus 14 is increased by a frequency controller 13, and the number of the stirring apparatus 15 is maintained at the prescribed value. Since the stirring shaft 4 of this stirring apparatus is arranged on the central shaft, the shaft-sealing part is unnecessary and the leakage of the fluid outside is not generated.

Error equations are formed based on the horizontal angle and the elevation angle from the observed data and the distances between the fixed points of the subtense bar 2. Then, the approximate values are obtained from the observed data and substituted into the error equations. There are 11 error equations for the eight unknown values. Therefore, when the method of least squares is utilized, the unknown coordinates can be theoretically operated. Since the three targets can be formed in spherical shapes furthermore, the sighting errors can be reduced.
