Title: Manufacture of vertically magnetized oxide film
Inventor: TOKITA TOSHIAKI
IPC: G11B11/10
Filed: 1986-12-23
Abstract: PURPOSE:To improve the magnetic characteristic and the magnetic optical characteristic of a magnetic film by heating to react a nitric acid solution containing Fe ions and Co ions, then coating a substrate with the solution, drying it and thermally decomposing it to crystallize it. CONSTITUTION:When a nitric acid solution containing Fe ions and Co ions is heated, it advances a reaction with foaming to discolor the solution. When it is cooled to stop the reaction, a substrate is coated with it to form a coated film and to dry it. These steps are repeated until the film of predetermined thickness is obtained. Then, it is annealed at a high temperature to be thermally decomposed to form a crystallized cobalt ferrite film on the substrate. Thus, a magnetic film which has excellent stability, large coercive force, large magnetic optical effect and an easy increase in its area can be formed.

Title: Digital multiplex transmission system
Inventor: ICHIBAGASE HIROSHI
IPC: H04J3/00
Filed: 1987-12-07
Abstract: PURPOSE:To obtain a digital multiplex transmission system which has transmission line codes of high changing point rates even to an input of a fixed pattern by arranging a sum converting circuit between a multiplexing circuit and modulator and a differential converting circuit between a demodulator and demultiplexing circuit. CONSTITUTION:A frame produced by a multiplexing circuit 5 is inputted to a sum converting circuit 10 and sums of the data of each bit and data of one bit before are successively taken and sum conversion is performed. Since the frame sent from the multiplexer circuit 5 has mark rates, almost of which are concentrated at 50%, the changing point rate of the circuit 5 is concentrated at nearly 50% as a result of the sum conversion. A modulator 6 sends the output of the multiplexing circuit 5 to a transmission line 7 after performing modulation on the output in accordance with the transmission form. In receiving a transmission line code, a demodulator 8 sends the code to a differential converting circuit 13 after performing demodulation and timing reproduction on the code. The timing reproduction can be performed extremely stably, since the changing point rate of the transmission line code is nearly 50%. The transmission line code inputted to the circuit 13 is sent to a demultiplexing circuit 9 after the differences between the data of each bit and data of one bit before are successively taken and differential conversion is performed.

Title: Method for preparing slag sample for fluorescence x-ray spectroscopy and sampler
Inventor: YAMAMOTO AKIRA
IPC: G01N1/28
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To enable on-line instruction to smelting operation by subjecting the surface of a solidified slag adhering to a hollow prismatic quenching body in contact with the quenching body to fluorescence X-ray spectroscopy and speedily and accurately analyzing it. SOLUTION: A hollow prismatic quenching body 1 is supported by a paper tube 4, and a slag separating material 2 is applied to the periphery of the hollow prismatic quenching body 1 to form a smooth surface. In addition, the hollow prismatic quenching body 1 is a prism of, for example, 3 mm in thickness with a side of approximately 50 mm in consideration of easiness in handling a sampler at an operation site and further obtaining a smooth and flat sample. After bringing a molten slag into contact with the surface of the hollow prismatic quenching body 1. the hollow prismatic quenching body 1 is immediately pulled up, and the contact surface of the slag with the quenching body 1 is prepared as an analytical surface of fluorescence X-ray spectroscopy.  In considering that the analytical depth in fluorescence X-ray spectroscopy is a few μm, there is no problem at all in quenching into a glass form in this range. Therefore, it is possible to use the hollow prismatic quenching body formed of a metal plate relatively thin in thickness.

Abstract: PURPOSE:To adjust the position of a head to the direction crossing vertically to a recording surface and to prevent any damage on a recording medium by constituting a member supporting a first head that is supported fixedly so that it can be deformed. CONSTITUTION:The magnetic head 3 provided on the lower surface of a disk 1 is supported by an arm 16, and a head 6 on the upper surface is elastically supported by an arm 5. The rear half of a slender board type arm 16 is engaged in the groove 8c of a carriage 8; an oscillation absorber material 18 is packed in the clearance between the recessed part 8d of the carriage and the upper surface of the arm 16.

IPC: G11B20/10
Filed: 1992-11-18
Abstract: PURPOSE:To reduce deterioration in picture quality due to errors by laying out signal points where the distance between signal points in that the upper bits of digital signal trains which are input in multiple-valued amplitude/phase modulation differ, is longer than the distance with other points for nearly leading to an error in lower bits when an error occurs.

The signal train 310 is input to a mapping circuit 5, a signal point is laid out on a constellation plane, and then two-system I signal 510 and Q signal 520 corresponding to the signal point position are output to an orthogonal modulation circuit 6 from the mapping circuit 5. Orthogonal modulation results due to a carrier 71 from a burst signal addition circuit 7 in the circuit 6 and then the modulation signal 61 is input to a burst signal addition circuit 8. A burst signal is added in the circuit 8 and an AC bias signal 9 is superposed by a bias addition part 10, thus recording on a recording medium 13 by a magnetic head 12. In this case, signal points are laid out so that the spacing of signal points, where the further upper bits of M-bit digital signal trains differ, is larger in the circuit 5.

Title: Displacement detecting device
Inventor: MIYAZAKI HIRONARI
IPC: G01L3/14
Filed: 1987-12-08
Abstract: PURPOSE:To obtain the displacement detecting device which can compensate exactly temperature and sensitivity by providing a pair of magnets which are provided adjacently in the displacement direction of a moving body and magnetized to the opposite polarity to each other and two Hall elements corresponding thereto. CONSTITUTION:Displacement detecting voltages whose phases have been shifted are outputted from Hall elements 7 (7a, 7b) provided by holding a prescribed period in the displacement direction of a moving body 1 opposed to a pair of magnets 4 (4a, 4b) which have been magnetized to the opposite polarity to each other. Both these displacement detecting voltages control an input current inputted to the elements 7 in accordance with its difference value in a current control circuit. In such a way, when a temperature of the periphery of the elements 7 rises, the sensitivity of the elements 7 drops, and also, a magnetic field of the magnets 4 also becomes weak, an inclination of the detecting voltage against a displacement of the elements 7a, 7b becomes small, and in accordance therewith, a difference value of both the displacement detecting voltages becomes small. Accordingly, since an input voltage to the elements 7a, 7b is increased by the current control circuit, the inclination of the displacement detecting voltage against the displacement of these elements is corrected, temperature and sensitivity are compensated, and an exact displacement detecting voltage is obtained.
