Title: Cooling method for coiled wire rod
Inventor: INOUE SATORU
IPC: B21B43/00
Filed: 1978-04-28
Abstract: PURPOSE:To cool coiled wire rod uniformly, by sending air blast to the moving coiled wire rod while it is oscillating by magnetic action. CONSTITUTION:Wire rod 1 is coiled by a reel 4 and travels on a conveyor 2, it is then bundled by a bundling tab 5. While traveling, the wire rod 1 is blown ceaselessly with air blast by plural blowers 6. Magnetic plates 3 are installed on rollers 8 set above the conveyor 2 and moved back and forth by a driving mechanism 7 through turning on or off the current applied to the magnetic plate 3. When the current is turned on, the coiled wire rod is raised up to form large gaps between adjacent loops. Air blast passes through the gaps sufficiently. When the current is turned off, the coiled wire rod lies down. Repeated on or off of the current applied to the magnetic plate 3 causes the coiled wire rod 1 to oscillate on the conveyor 2 so that the parts adjacent to each other of the coil separate or overlap alternately. Hereby, the coil is cooled uniformly. Consequently, the wire rod shows uniform sorbite structure over whole length, and breaking of the wire during drawing can be prevented.

Title: Magnetic sensor
Inventor: SUGIYAMA TAKEHIRO
IPC: G01R33/07
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To prevent the sensitivity from lowering and to make the yield rate higher, even if the condition of a semiconductor surface changes a little, by forming two-dimensional electron gas layers on both sides of the surface and the rear of an n-type semiconductor layer being a carrier supply layer. SOLUTION: Two-dimensional electron gas layers 8, 9 are formed in the heterojunction interface between a first un-GaAs layer 2 and a first un-AlGaAs layer 3 and in the heterojunction interface between a second un-AlGaAs layer 5 and a second GaAs layer 6 respectively. Since the two-dimensional electron gas layers 8, 9 are formed at places of the lowest Fermi level, namely at places sufficiently far from crystal surfaces, the energy condition of an n-AlGaAs layer 4 being a carrier supply layer does not change very much, even if the condition of a semiconductor surface changes a little.

Title: Method of integrally mounting slender electric heater to mold member
Inventor: JIYOBUSUTO URURITSUHI GERAATO
IPC: B29C63/34
Filed: 1983-03-30
Abstract: This invention relates to an improved method of installing an elongated heater such as a cartridge heater in a molding member such as an injection molding manifold member. First, a bore is drilled into an elongated portion of the manifold member to extend generally parallel to the hot runner passage extending through it and a filler duct is drilled from the top to intersect the bore along its length. The cartridge heater is then inserted into the bore and a filler tube with a base is set on the top in alignment with the filler duct. A brazing paste is then applied around the base of the filler tube and around the terminal portions of the cartridge heater extending from the bore. The manifold member is then heated in a vacuum furnace which brazes the filler tube in position and seals the outer end of the duct against leakage. A slug of copper is then inserted into the filler tube and the manifold member is again heated in the vacuum furnace sufficiently to cast the conductive copper to fill the space around the cartridge heater. The filler tube is then machined off to produce the finished manifold member. The copper fuses to the outer casing of the cartridge heater and the bore and together with the elimination of the insulative air space around the cartridge heater substantially improves heat flow and reduces the formation of hot spots which cause the heating element to burn out. In another embodiment, a tubular heater having two terminal portions is installed in a heater plate of a thermosetting mold with the terminal portions extending at opposite ends of the heater plate.

Title: Compliance controller for manipulator
Inventor: SHIGESADA MASARU
IPC: G05D3/12
Filed: 1993-02-17
Abstract: PURPOSE:To prevent a terminal point from entering a singular point area by adding virtual external force for not letting the terminal point of a manipulator approach a singular point. CONSTITUTION:A singular point information storage part 8 stores the geometrical shape information of the singular point area of the manipulator 1. A virtual external force vector calculation part 9 calculates a relative position vector for supplying a shortest distance from the singular point area to a present position, calculates a unit vector in the same direction, also calculates a function for which the length of the relative position vector is made a variable and obtains a virtual external force vector for which a function value is multiplied by the unit vector. An external force vector adder 10 obtains the resultant external force vector which is the sum of an actual external force vector outputted from a force sensor and the virtual external force vector. Since control is performed by adding the virtual external force, the terminal point is prevented from entering the singular point area.

Abstract: PURPOSE:To obtain a polymer having good whiteness without causing discoloration, by adding a small amt. of malic acid before starting the soln. polymn. of acrylonitrile in a specified solvent and separating and removing unreacted monomer after the polymn. CONSTITUTION:In the soln. polymn. of a mixture of 80wt.% or more acrylonitrile, another polymerizable vinyl compd.

After the rate of polymn. reaches 40-70%, unreacted monomer is separated and removed. As described above, by adding in advance malic acid as a coloration inhibitor, stopping the polymn. at said rate of polymn. where the velocity of polymn. is not yet lowered and separating and removing unreacted monomer, it is possible to prepare advantageously a polymer having excellent whiteness without causing discoloration.

Abstract: PURPOSE:To improve the current amplification factor of a high current region and to enable to integrate a semiconductor in the reduction of the size of a pattern by forming the base region in a lateral transistor having one conductive type base region formed across an emitter region and a collector region on the surface of conductive type semiconductor region in a high impurity density higher than the one conductive type semiconductor region. CONSTITUTION:P type regions which form an emitter region 12 and a collector region 13 are respectively formed in an N type region formed in an epitaxial wafer 11. Subsequently, N<+> type impurity of high density is diffused in a depth shallower than the P type regions across the two P type regions to form an N<+> type base region 14. The impurity N of the region 14 and the impurity density P in the P type region have a region of N>P, to be formed in a depth as shallow as possible with the region sufficient to form a base electrode 18. An emitter electrode 16, a collector electrode 17 and a base electrode 18 are formed. In this manner, the flow of a base current becomes short, thereby reducing the base resistance and improving the current amplification factor in the high current region.

Title: Production of triphenyl phosphite
Inventor: UCHIDA KATSUMI
IPC: C07F9/145
Filed: 1993-02-19
Abstract: PURPOSE:To remove accompanying phenol from a hydrogen chloride gas as a by-product in producing triphenyl phosphite by reacting phenol with phosphorus trichloride. CONSTITUTION:A hydrogen chloride gas as a by-product is passed through a water trap and absorbed and the absorption solution of the water trap is circulated through an active carbon adsorption layer to adsorb and remove the absorbed phenol. Since the absorption water in the water trap is circulated through the active carbon layer to remove phenol, the absorption water in the water trap always maintains the concentration of dissolved phenol at a low level and phenol is efficiently absorbed in the water trap. On the other hand, since phenol having high concentration is adsorbed on active carbon, the active carbon has high saturation adsorption ability and the amount of active carbon used is saved.
