Title: Production of magnetic recording medium
Inventor: SUGITA RYUJI
IPC: C23C14/54
Filed: 1987-03-05
Abstract: PURPOSE:To obtain the titled medium having high S/N by forming a thin Co- base alloy film having perpendicular magnetic anisotropy by a vacuum deposition method on a traveling substrate at a film deposition speed of >=800Angstrom /sec in an atmosphere contg. gaseous H2 at the ratio higher than the ratio of other gases. CONSTITUTION:The substrate 1 travels in an arrow A direction along a cylindri cal can 2. a shielding plate 5 is disposed between an evaporation source 6 and a can 2. Evaporating atoms 7 adhere to the substrate 1 through a slit S. the adhesion of the atoms 7 to the substrate 1 begins in an initial part B of film formation and ends in a terminal part C of the film formation. The gaseous hydrogen is introduced through a gaseous hydrogen introducing pipe 8 into a vacuum vessel and is blown out of a hole 9. The substrate 1 from a supply roll 3 is taken up on a take-up roll 4 and the atoms 7 are deposited thereon by evaporation, by which the film is formed at the film deposition speed of >=800Angstrom /s. The thin film type magnetic recording medium for perpendicular recording having high S/N in a short wavelength region is thereby obtd. even if the substrate 1 such as polyethylene terephthalate film having poor heat resistance is used.

After completing the culture, the resultant culture solution is then centrifuged to remove microbial cells. Hydrochloric acid is subsequently added to the obtained culture supernatant to separate precipitates such as the unreacted substances. The residual solution is subsequently extracted with ethyl acetate, etc., and the solvent in the extract solution is then distilled away to collect the prepared reaction product, which is further subjected to high-performance liquid chromatography and purified. Thereby, the objective compound is obtained.

Title: Bias magnetic field generator for magneto-optical recording
Inventor: ASAKO KOJI
IPC: G11B5/02
Filed: 1990-03-02
Abstract: PURPOSE:To improve the generation efficiency of a magnetic flux density in the vicinity of the surface of a core top by surrounding a side face of a coil with a side yoke, covering the upper face of the coil with a top yoke and forming a prescribed magnetic gap between an end face in the broadwise direction of the core top and an end face of the top yoke. CONSTITUTION:A couple of side yokes 4 are arranged on both sides of a core 2 along the lengthwise direction of a core top 1, a side yoke 4 surrounds the side face of a coil 3 and is linked magnetically to the core 2 and a top yoke 5 is arranged on the upper part of a couple of side yokes 4 incorporated in the coil 3. Then a prescribed gap is specified between the side face in the broadwise direction of the core top 1 placed to surround the core top 1 and the side face of the core top. That is, since the core top 1 and the top yoke 5 are arranged closely via a prescribed gap, the magnetic flux easily passes through the gap. Thus, the magnetic reluctance of the magnetic circuit is reduced and the total magnetic flux quantity is increased. Thus, the effective magnetic flux density in the vicinity of the surface of the core top 1 is increased.

Title: Vacuum deposition device
Inventor: FURUKAWA HEIZABUROU
IPC: C23C14/56
Filed: 1984-03-19
Abstract: PURPOSE:To improve the yield of the metal to be deposited by evaporation and the working efficiency of an installation with a device for plating continuously a metal by vacuum deposition onto a steel hoop by suppressing the reevaporation of the metal subjected to the vacuum deposition. CONSTITUTION:A steel hoop 1 is conducted via a vacuum sealing device 31, etc. to a vacuum vessel 2 in which a low pressure is maintained. The evaporating metal, for example, Zn vapor 5, from an evaporation vessel 4 is plated by vapor deposition on said hoop in the stage when the hoop is guided by a roll 3. The hoop is again conducted via a high pressure sealing device 6, etc. to the high pressure side. The vapor 5 everges off the roll 3. Inner ducts 12 heated by heaters are provided to the arc-shaped covers 10, 11 provided in the inlet of the roll 3 and are connected to the sealing bar 13 of the device 6. The Zn 8 evaporating again from the hoop 1 is thus suspended in the ducts 12 without vapor deposition. The reevaporation is eliminated when the partial pressure of the Zn vapor attains the satd. vapor pressure P1 at the reevaporation temp. of the solid Zn in the hoop 1. The reevaporation is kept suppressed even if a large amt. of the plated hoop 1 passes through the inside of the ducts 12 after the attainment of the pressure P1 and therefore the yield of Zn is improved and the working efficiency of the installation is improved as well.

Abstract: PURPOSE:To reduce the degradation of an error rate for a reproduced master signal even when the amplitude and frequency of an FM modulating system are increased, and to prevent the transmission quality of an auxiliary signal from getting adverse by specifically processing the auxiliary signal. CONSTITUTION:At a transmitter, the amplitude level of the auxiliary signal is detected by a first variable amplitude/frequency converting means 33, an amplitude/frequency characteristic is applied to the auxiliary signal and outputted corresponding to this detected level, and the auxiliary signal is FM modulated at a prescribed frequency by an FM modulating means 32 and outputted. As the master signals, two multi-level amplitude modulated base band signals are multi-level orthogonally amplitude modulated by a multi-level orthogonal amplitude modulating means 31, and the FM modulated auxiliary signal is composite modulated to this modulated signal and outputted. At a receiver, the master signals are demodulated by suppressing the FM modulated component of the composite modulated signal at an orthogonal amplitude modulated signal demodulating means 41 and outputted together with the auxiliary signal. A second variable amplitude/frequency converting means 42 applies a characteristic inverse to that of the first variable amplitude/frequency converting means 33 to the auxiliary signal to be outputted and outputs the auxiliary signal.

Filed: 1988-03-04
Abstract: PURPOSE:To produce an optical isolator having good performance especially in <=0.8mum band by growing a magnetic garnet film on a nonmagnetic garnet substrate by the liquid phase epitaxial method and accumulating another magnetic garnet film on said film by the sputtering method to adjust the angle of Faraday rotation without grinding. CONSTITUTION:A magnetic garnet film 5 is grown on a nonmagnetic garnet substrate 4 by the liquid phase epitaxial (LPE) method, and this LPE film 5 is set to such film thickness that the angle of rotation is smaller than Faraday rotation angle 45 deg. of an objective wavelength,and a sputter film 6 is deposited on the film 5. Since the film forming speed of the sputter film 6 can be easily controlled, adjustment due to grinding is unnecessary. Thus, a magneto-optical element is obtained which has the angle of Faraday rotation in the range of 45+ or -0.05 deg. even in <0.8mum band and has satisfactory insertion loss isolation.

Title: Coordinate input device
Inventor: TAKAHASHI MITSURU
IPC: G06F3/03
Filed: 1991-03-15
Abstract: PURPOSE:To input exactly, stably the coordinates even with the fine input requiring high precision by using a film or a thin plate of a photoconductive material responsive to the light beam of a specific wavelength to separate two counter resistance films from each other and also using an input pen which units the light flux through its tip. CONSTITUTION:When the light flux is projected on an input panel through a window 41 of an input pen 4, a separator layer (plate) 3 is locally conductive at the part radiated by the light flux owing to the photoconductive properties and two resistance films 1 and 2 are electrically connected to each other at the radiated part. The coordinates to be detected are added with the constant voltage or current by X or Y on the film 1 or 2. Thus if the local and electrical connection is secured between both films 1 and 2 at the position of the pen 4, the voltage is given to one of both films in response to the position of the pen 4. This voltage is led out to an external detecting circuit through the electrodes 11 and 12 or the electrodes 21 and 22. Then the X or Y coordinate can be detected by the voltage.
