Title: Magnetic head device
Inventor: OMOTO HIROYUKI
IPC: G11B5/60
Filed: 1986-05-12
Abstract: PURPOSE:To improve adhesion between a magnetic gap, and the surface of a magnetic recording medium, by curving a center part including the magnetic gap in a projecting shape so as to protrude higher than a leading end part and a rear end part, and curving the slidable contact plane of the magnetic recording medium of a slider part in a recessed shape with the radius of curvature larger than that of a core part. CONSTITUTION:A magnetic head 1 consists of a magnetic core 2, a magnetic core supporting body 3, and a recording and reproducing coil, and the slidable contact plane 4a of the core part is processed, for example, in a circular arc with a radius R so that the center part of the plane is protruded to be travelling direction of the magnetic recording medium. Also, the slidable contact plane 5 of the slider part is processed in the recessed shape with the radius equal to, or larger than the radius R formed in the projecting shape. Therefore, the slidable contact plane side of the core part is brought into contact slidably with the magnetic recording medium only in the neighborhood of the magnetic gap, thereby, a pressing force is increased, and performance is stabilized, and influence due to waving, or tramp is reduced by a part separating both ends of the slidable contact plane of the core part from the magnetic recording medium, and the floating of the magnetic head due to the waving is hard to generate.

Title: Flow control device for helical suction port
Inventor: MAEDA YORISHIGE
IPC: F02B31/00
Filed: 1981-07-15
Abstract: PURPOSE:To have a secure control over opening and closing of the divergent line from an opening and closing valve in the divergent line by putting an oil pressure chamber for actuation of the piston in communication with the passage for lubricant oil. CONSTITUTION:A divergent line 14 leading from the intake passage to the ending part of swirling is formed in the cylinder head, and a slide valve 18 is furnished in this divergent line 14, being equipped with a valve element 20 to control opening and closing of the divergent line 14. The oil pressure chamber 30 for actuation of the piston 22 is connected with a lubricant oil supply pump through lubricant passages 32-35, 37 and a solenoid-operated opening/closing valve 36. This solenoid-operated valve 36 is connected to the output terminal of an electronic control unit 38. The reliability can be enhanced because the opening/closing control of the divergent line can be thus made with simple mechanism using the lubricant oil pressure.

Title: Magnetic head
Inventor: HAYAKAWA WATARU
IPC: G11B5/23
Filed: 1980-08-11
Abstract: PURPOSE:To obtain a magnetic head which is capable of the high density recording and the high sensitivity reproducing in a vertical magnetic recording system. CONSTITUTION:A magnetic head 11 includes a U-shaped ferrite core 13 wound with a winding 14 plus a main magnetic pole 16 and an auxiliary magnetic pole 16 having the faces opposite to a recording medium respectively. The core 13 can be made of a thin film magnetic material at the side of the pole 15 and a bulk magnetic material at the side of the pole 16 instead of one and same material. The length L1 of the pole 15 is set small enough to ensure the concentration of magnetic flux; while the length L2 of the pole 16 is set large enough to avoid the concentration of magnetic flux respectively. It is better to form the corner part 17 of the pole 16 into a curved surface to avoid the local concentration of magnetic flux. The magnetic flux starts the head 11 and returns to the head 11 after passing through a recording medium 12. The magnetic field of the pole 16 is small since the area opposite to the medium 12, and accordingly the recording is carried out at the position of the pole 15.

Title: Method and apparatus for measuring distribution of zero dispersion wavelength of optical fiber
Inventor: NISHI SHIGETO
IPC: G02B6/00
Filed: 1995-05-08
Abstract: PURPOSE:To measure the distribution of zero dispersion wavelength in the longitudinal direction of an optical fiber by observing the backscattering waveform of a light pulse indicating the power distribution of the light pulse in the longitudinal direction of the optical fiber. CONSTITUTION:In a light pulse tester 10, a light pulse is made incident on an optical fiber to be measured 6. A backscattering light is generated at each part in the fiber 6 when the light pulse propagates. In the tester 10, the backscattering light generated and returned from each part of the optical fiber 6 is split by a directional coupler 13 and detected by a high-speed photodetector 14. A waveform of the light is displayed at a display part 15. The backscattering light is continuously returned from each part during the propagation of the light pulse. The backscattering light from a further part takes a longer time to return to the entering end. Therefore, the waveform of the backscattering light expands more in comparison with the light pulse incident upon the fiber 6. A distribution of power of the light pulse in the longitudinal direction in the fiber 6 can be detected by observing the waveform. A zero dispersion wavelength of a part of the fiber 6 where a modulation instability is generated, is accordingly determined.

Abstract: PURPOSE:To efficiently manufacture flaky soft magnetic fine powder having <=240A/m coercive force by mechanically pulverizing raw material powder with saturation magnetostriction constant and contents of Si and Al specified into the specific particle diameter and thickness. CONSTITUTION:Molten Fe-Ni series alloy having + or -15X10<-6> saturation magnetostriction constant measured with a bulk material and adding >=0.3% Si and >=0.05% Al, is atomized with water atomizing method to obtain the irregular shaped alloy powder. This alloy powder is mechanically pulverized as the raw material to 0.1-20mu average particle diameter and <=1mu average thickness and annealing is applied while keeping the flaky shape of the fine powder after pulverizing to make <=240A/m coercive force. The above Si and Al show improving effects of pulverization ability for raw material and soft magnetization and the improving effect of pulverization ability are not shown unless these elements are added more than the lower limits, and the soft magnetization is improved as increasing these elements, but when these elements are added too much, oxidation of the powder at the time of atomizing progresses greatly, therefor, the contents are practically limited to 3% Si and 1% Al.

CONSTITUTION:The molten iron which is subjected to desiliconization, dephosphorization and desulfurization by pretreatments is charged into a top and bottom blown converter, and blowing is carried out by regulating the height of a top blowing lance and the rate of oxygen feed in such a way that the ratio L/L0 between the depression depth L in a steel bath by top-blowing oxygen and the depth L0 of the steel bath attains <=0.40. In the first half of the blowing, the top- blowing oxygen is blown at >=2.6Nm<3>/min per ton of molten steel, and upon lapse of the time corresponding to 60-80% the entire volume of the oxygen to be fed, the rate of the top-blowing oxygen is reduced to <=2.5Nm<3>/min per ton of the molte steel. The fume loss of the iron is suppressed as far as possible and the high level of the content of Mn is assured.

Filed: 1990-04-26
Abstract: PURPOSE:To improve the productivity of programs by securing the correspondence between a macro definer transformed into a subroutine and a program and at the same time evolving the macro definer when the execution of the program is processed. CONSTITUTION:An instruction producing part 20 transforms the using definition of a macro definer 4 described in a program 1 into a subroutine call instruction. A subroutine generating part 21 sets newly the subroutine which is called out by a call instruction produced by the part 20 and at the same time sets the address information on the store area of the definer 4 serving as a transformer of the call instruction to the set subroutine. A macro evolving part 30 evolves the definer 4 if this definer 4 pointed by the subroutine called by the call instruction is not evolved yet when the call instruction produced by the part 20 is carried out. Thus the program productivity is improved.
