Title: Method for preventing surface defect at edging of cast slab
Inventor: WAKAO MASAMITSU
IPC: B21B1/02
Filed: 1995-04-13
Abstract: PURPOSE: To prevent the occurrence of cracks at the time of edging of a continuously cast slab by adding a specific amount of Ti at the time of continuously casting a carbon steel having a composition containing Nb(CN) and V(CN). CONSTITUTION: After Ti is added by 0.01-0.06% by weight to a molten steel having a composition which contains 0.001-0.5% C, 0.002-0.015% N, and either or both of 0.02-0.1% Nb and V and in which Al content is controlled to <=0.008%, the resultant molten steel is continuously cast into slab by a continuous casting process. In this continuously cast slab, at the time of γ-α transformation under cooling, precipitates, such as Nb(CN) and V(CN), are precipitated as matrix in the crystalline grains of a steel while Ti oxides serve as precipitation nuclei.  Although embrittlement bounded by crystalline grain boundaries is brought about at the time of edging the continuously cast slab in the case where Nb(CN) and V(CN) are precipitated in the crystalline grain boundaries, the occurrence of embrittlement induced by the crystalline grain boundaries at the time of reduction working can be prevented because Nb(CN) and V(CN) are precipitated in the crystalline grains.

Title: Torque detecting apparatus
Inventor: SEDAKA YASUSUKE
IPC: G01L5/22
Filed: 1988-05-07
Abstract: PURPOSE:To use a detecting apparatus as a motor driven power steering part and to make it possible to measure static torque, by providing two magnetic flux paths in a space between two rotary bodies and detecting the difference in magnetic flux quantities of both magnetic flux paths, which is yielded by the displacement between the rotary bodies. CONSTITUTION:A driving shaft 1 is coupled with the steering wheel of a vehicle. An output shaft 2 drives and steers wheels. The shafts 1 and 2 are linked with a torsion bar 3. An inner rotor 11 and an outer rotor 12, which form magnetic circuits, are fixed to the shafts 1 and 2. A stator 14 (differential transformer) is provided at the outside of the rotor 12. Gear teeth having the same pitch are provided on the rotors 11 and 12 at two places so as to face each other through a gap 26, and two magnetic paths are formed. The teeth of the rotor 11 are shifted by every 1/2 pitch. When the relative positions of the teeth of both rotors are changed, the magnetic fluxes passing through the magnetic resistor of the magnetic path are changed. The output voltages of detecting coils 17-b and 18-b of the stator 14 are changed. Since the amplitude and the phase of the differential output voltage are changed in correspondence with the torsion angle (change in relative positions of the teeth) of the bar 3, the torque can be detected.

Title: Insulating magnetic toner
Inventor: SATSUTA KEISUKE
IPC: G03G9/083
Filed: 1987-05-07
Abstract: PURPOSE:To obtain an insulating magnetic toner having excellent fixability, running resistance, environmental resistance, image characteristic, etc., by using specific flat type magnetic powder for magnetic powder. CONSTITUTION:The flat type magnetic powder having >=65emu/g intensity of magnetization in 1kOe external magnetic field and >=3m<2>/g BET surface area is used. The magnetic powder has usually <65emu/g intensity of magnetization in 1kOe external magnetic field. The restraining power that the toner particles receive on a magnetic sleeve is proportional to the intensity of the magnetization in the magnetic field on said sleeve and if the same magnetic powder is used, the intensity of the magnetization of the toner particles is usually proportional to the content of the magnetic powder contained in the toner. The intensity of the magnetization in the same external magnetic field as the magnetic field of the magnetic powder on the magnetic sleeve is, therefore, increased, by which the content of the magnetic powder required to obtain the same restraining power can be decreased. Exposing of the magnetic powder onto the toner surface and the dislodgment of the magnetic powder from the toner are thereby decreased and the insulating magnetic toner having the excellent fixability, running resistance, environmental resistance, image characteristic, etc., is obtd.

Abstract: PURPOSE:To prevent the short-circuit between a collector and an emitter by a method wherein a base layer is provided by using a buried oxide film, a bird beak is removed by etching thereafter, selective oxidation is made again to prepare the second buried oxide film, and then an emitter layer is provided. CONSTITUTION:An Si3N4 mask 13 is given to a thermally-oxidized film 12 on an N type Si 11, wet oxidation is applied thereto at 1,000 deg.C, and thereby a buried oxide film 14 is formed. Then, a resist mask 18 being given, P type ions are implanted in the film to prepare a base layer 15. Next, the film 14 is etched about 0.7mum deep by a buffer HF solution to expose a part of a substrate, and, by using the Si3N4 again, wet oxidation is applied thereto for about one hour at 900 deg.C and under the atmospheric pressure of 6atm. Thereby the depth of junction is increased by about 0.2mum in the part wherein the oxide film is formed, by the distortion caused by oxidation, while the depth of base junction is almost unvaried. Then, an element is formed by a conventional method. The depth of base junction is made larger than that of other parts by an additional process of selective oxidation, an emitter pattern is transferred into a similar base pattern, and the width of a base is made larger than others. Accordingly, the short- circuit between a collector and an emitter is prevented and thus an yield rate is improved.
