Title: Liquid-phase epitaxial growth apparatus
Inventor: HIROTA KOJI
IPC: C30B29/48
Filed: 1990-10-12
Abstract: PURPOSE:To manufacture a compound semiconductor crystal whose quality is good by a method wherein a melt-material housing chamber which houses a melt material collectively is partitioned and formed on the rear side of a substrate for crystal growth use at a jig and a through hole is made in a partition between the melt-material housing chamber and a chamber, for crystal growth use, which has been partitioned and formed by an ampule and the jig. CONSTITUTION:A metal material 21 composed of Hg1-xCdxTe which has been weighed in advance in a prescribed composition ratio is mounted and housed inside a recessed part 18 at a jig 14. It is arranged and installed inside a quartz ampule 12. Its inside is evacuated and sealed airtightly. After that, the quartz ampule 12 is arranged inside a liquid-phase epitaxial growth furnace; it is heated up to a prescribed temperature (e.g. 800 deg.C). Thereby, the melt material 21 is melted; it flows out to a chamber 25 for crystal growth use via through holes 20; it is changed to a molten melt material 21. Although an oxide film 26 floats on its liquid face, it cannot be passed through the through holes 20 and is left inside a melt-material houding chamber 24. Then, the qurtz ampule 12 is turned; a substrate 22 for crystal growth use is immersed in the molten melt material 21'; the temperature inside the furnace is lowered to a prescribed crystal growth temperature. Thereby, a crystal layer 27 composed of Hg1-xCdxTe is precipitated and grown on the substrate.

IPC: C21D1/26
Filed: 1990-10-12
Abstract: PURPOSE: To approximately completely graphitize a heat treated steel of a specific compsn. having a specific carbon content and to enhance its cold workability by subjecting this heat treated steel to final cold working and hardening, and annealing under specific conditions before subsequent tempering.  
     CONSTITUTION: The steel having the compsn. consisting, by weight %, of 0.32 to 0.54 C, 0.05 to 0.40 Mn, 0.41 to 1.5 Si, 0.02 to 0.15 Al, ≤0.05 Cr, ≤0.05 S, ≤0.03 P, ≤0.02 N and the balance iron is subjected to annealing for ≥15 hours at 620 to 680°C. This steel is then subjected to the final cold working and the hardening and the subsequent tempering. The cementite of the lamella pearlite in the ferrite-pearlite steel and pearlite steel having the compsn. described above is transformed to graphite and the graphite particles are definitely larger than the cementite particles thereby precipitation hardening does not occur. Consequently, the strength degrades drastically and the cold workability is improved.

Title: Method for inspection of scanning signal dependent on position and controller therefor
Inventor: HOLZAPFEL WOLFGANG DR
IPC: G01R35/02
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To display parameters of a scan signal with high resolution and high accuracy by a method wherein a controller obtains a value of a fluctuating width of a radius from a series of radius values and displays it on a display field. SOLUTION: A scan head 3 scans a measure 1 having incremental scales 2, and its scanning elements F1 , F2 output analog scan signals S1 , S2 . The scan signals S1 , S2 are interpolated to lower units for obtaining a position measurement values, and their resolution is better than a scale pitch P. In addition, a target position state is shifted in phase by ϕ=90 deg. to have high signal amplitude to assure highly accurate interpolation. Therefore, a controller 4 can inspect these parameters (phase state, amplitude) especially effectively. The controller 4 calculates a series of radius values from a plurality of values (signal amplitude) of the scan signals S1 , S2 and displays a continuous bar 9 between the minimum and maximum values on a display field 8 as a value of a fluctuating width.  Thus the parameters of the scan signals S1 , S2 can be displayed with high resolution and high accuracy.

IPC: G11B23/087
Filed: 1985-12-05
Abstract: PURPOSE:To form an accurate peripheral wall by forming a ring body at first, then using this as a male mold to form a outer layer part. CONSTITUTION:Although a recessed part (a) due to shrinkage is generated on the thick-walled peripheral part 3a of the outer ring body 3 of a ring body 2 because the ring body 2 is formed at first in the production of a tape reel, the outer layer part 10 is formed on the periphery of the outer ring part 3 as a male mold and the peripheral surface 3a is filled with the layer part 10. Since the outer layer part 10 is formed with thin resin or resin extremely smaller than the volume of resin forming the ring body 2, the recessed part (a) due to shrinkage is not almost generated in the outside 11 of the outer layer part 10. Even if the shrinkage is generated on the outer layer part 10, the shrinkage will be generated only to the formed thickness of the outer layer part 10, so that the shrinkage is extremely smaller than that of the single united formation of the peripheral wall 13 of the tape reel 1 and the accurate peripheral wall 13 corresponding to a design value can be formed.

Title: Magnetic levitation carrying device
Inventor: KAWADA NORIYUKI
IPC: B65G54/02
Filed: 1990-10-12
Abstract: PURPOSE:To reduce oscillation in a travel direction by forming a floating body with a main body member and a pair of protruded members in a direction orthogonal to a carrying direction in both the side parts of the main body member, and providing a slope part on the end surface orthogonal to a carrying direction on one side of the main body member and the protruded members. CONSTITUTION:A floating body 20 has a rectangular middle part 20a and a pair of protruded parts 20b and 20b protrudedly provided in a direction orthogonal to a travel direction in both the side parts of the middle part 20a. An extended part 20c is provided on four corner parts respectively formed with the protruded parts 20b and 20b and the middle part 20a. The providing of the extended parts 20c, on edges orthogonal to the travel direction of the protruded parts 20b and 20b like the floating body 20, causes the lowering of the maximum value of steering force in the travel direction, and the smoothing of the variation of the steering force in the travel direction when the floating body 20 is traveled. Consequently oscillation produced in the floating body 20 at the time of travel is reduced.
