Title: Production of magnetic recording medium
Inventor: HOYAMA MAMORU
IPC: G11B5/845
Filed: 1986-04-16
Abstract: PURPOSE:To obtain a recording medium which has excellent magnetic characteristics and is suitable for high-density recording by forming the medium in such a manner as to be closed in the traveling direction of a substrate by opposed N-S magnets and successively executing specific stages. CONSTITUTION:A closed magnetic path is formed by the opposed N-S magnets 5b, 5c so as to be closed in the traveling direction of the substrate 2. Said magnetic path forms the N-S magnetic field having the magnetic field intensity higher than the coercive force of magnetic power 4 incorporated in a magnetic coating compd. The substrate is introduced into such magnetic field and is run. The inversion of the magnetic field which acts on the magnetic powder particles 4 and inverts from positive to negative or from negative to positive as the substrate 2 travels is ended before the magnetic powder particles 4 start rotating by the effect of said magnetic field inversion while the magnetic coating compd. is cured. Only the direction of the magnetization of the magnetic powder particles 4 is inverted and the demagnetic field acting on the delivery side of the substrate 2 is also positively utilized for orientation of the magnetic powder particles 4. The axis of easy magnetization of the magnetic powder particles 4 is thereby additionally satisfactorily oriented in the direction perpendicular to the traveling direction of the substrate 2, by which the high-density recording is executed.

IPC: A61K47/10
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To prepare a low-viscosity, low-caloric and readily dryable sugar coating liquid, good in appearance and hardly changing with time. SOLUTION: This sugar coating liquid comprises 110-300 pts.wt., preferably 130-170 pts.wt. saccharide and/or maltitol based on 100 pts.wt. erythritol. The erythritol may be in a completely dissolved state or converted into a crystallite having <=100μm average grain diameter. The concentration of the erythritol and the saccharide (e.g. sucrose) and/or maltitol is 60-80wt.%. When the ratio of the erythritol in the sugar coating liquid is increased, erythritol crystals are deposited to prevent a cone and a plate from rotating and measurement cannot be carried out when measuring the viscosity. The size of the erythritol crystals is large and the texture of the resultant sugar-coated tablets is roughened. The sugar-coating liquid is useful as a coating agent for the confectionery, tablets, etc.

Title: Optical recording and reproducing device
Inventor: MIZUNO SADAO
IPC: G02B26/10
Filed: 1979-07-11
Abstract: PURPOSE:To fix securely a reflecting mirror, vibrating for tracking in reproduction, in recording by attracting and fixing a disk, formed in the same body with the rotary axis of the reflecting mirror of an optical recording and reproduction system, by a magnetic field provided by a coil. CONSTITUTION:In reproduction, switch 26 is changed over to disconnect electric power source 27 and input terminal 13. As a result, while electric power supply to coil 10 is shut off, the feedback output of differential amplifier 25 that corresponds to a track error excites coil 7 and reflecting mirror 1 of the optical recording and reproduction system vibrates via magnet 5 and returning elastic body 14 provided on its rotary axis 3 to perform tracking. In recording, once an electric power current is supplied from electric power source 27 to coil 10 via switch 26, magnetic disk 9 fixed on axis 3 is attracted by a magnetic field provided by coil 10 and then elastically deforms by coming into contact with yokes 11 and 12, applying damping force to axis 3. Axis 3 is therefore fixed securely and the generation of harmful vibrations of mirror 1 due to external force is prevented.

Title: Lowering device for noise in hydraulic braking of rotary shaft
Inventor: ISHIHARA AKIRA
IPC: F16H57/12
Filed: 1995-03-23
Abstract: PURPOSE: To reduce vibration and noise due to collision between the teeth faces of gears by restraining the fluctuations of torque and of rotation generated in a shaft rotated through the gears. CONSTITUTION: A rotary blade 4 is provided on a gear attached to a driving shaft 2 and functions as a rotor, and a stator is attached in the oil reservoir 8 of a plate 6 opposite to the rotor. An oil being made to flow from an oil intake port 9 into an oil reservoir 7 by the rotation of the gear 1 is discharged through the oil reservoir 8 from an oil delivery port 10. In this case, static pressure is generated by the pumping action of the rotary blade 4, and fluid interference is generated by the stator to fluctuate the static pressure at every time of the fluid interference. Torque being the reaction force of the fluctuating pressure acts on the driving shaft 2 as torque having a phase reverse to driven torque generated in the driving shaft 2 for offsetting the greater part of torque fluctuation generated on the driving shaft 2.  In a gear system, the static pressure acts between teeth faces being in mutual engagement to keep an almost zero backlash state for avoiding collision between the teeth faces.

Abstract: PURPOSE:To produce a single crystal silicon containing small amounts of crystal defects therein, by a method wherein an opening is formed in a strip pattern on the surface of a silicon substrate, so that a small dimension of the pattern width suitable for crystal growth can be selected regardless of the element size. CONSTITUTION:A silicon substrate 1 on a plane (100) is thermally oxidized to form a silicon oxide film 2 and subsequently an opening 11 is formed in a <100> oriented strip pattern. With this strip pattern of the opening 11, each of the pattern widths a and b is made a fine size in the range of 0.5-3mum so as to be suitable for crystal growth. Next, a silicon oxide film 3 and a silicon nitride film 4 are in turn formed and then a silicon oxide film 5 is formed on the bottom part of the opening 11 using the partially removed silicon nitride film 4 as a mask. Thereafter, the silicon substrate 1 is exposed from the sidewall of the opening 11, and a single crystal silicon film 6 is made epitaxially grow in vapor phase from the exposed silicon surface and the silicon film 6 is deposited in the opening 11 until the opening 11 is filled therewith. As a result, a single crystal silicon film can be formed which contains only small amounts of crystal defects.
