Title: Faraday rotator
Inventor: FUKUSHIMA NOBUHIRO
IPC: G02F1/09
Filed: 1984-07-28
Abstract: PURPOSE:To reduce the size of constitution and cope with error factors over a wider range by varying an angle of Faraday rotation by varying the magnetism direction of a magneto-optic material to light transmitted through the magneto- optic material. CONSTITUTION:A permanent magnet 3 having proper magnetic field intensity Ep is allowed to rock continuously around a center 4 of rotation over a range of, for example, + or -10 deg.. In this case, the angle of Faraday rotation of transmitted light 2 depends upon Ep.+ or -cos10 deg. and also depends upon costheta, so it is accurately variable. Therefore, an adjustment of the angle of rotation accompanying, for example, the replacement of a light source in use, variation in ambient temperature, etc., is easily made by rocking a permanent magnet 3 which is smaller and lighter than an electromagnet.

Filed: 1977-12-30
Abstract: PURPOSE:To grind the side faces of track faces and perform adjustment with high accuracy by placing a circular cylindrical lap bar in the groove parts forming the track faces and slider faces of a monolithic type head core and revolving the lap bar. CONSTITUTION:Track faces 1 are worked with a diamond wheel 3. When the need for adjusting the tack width aries, a high precision lap bar 4 of a circular  cylindrical shape is placed in the groove between the track face 1 and slider face 2 of the core. A gear 9 is mounted to the center of the lap bar 4 and is connected to a motor shaft 11 by means of chain 10. The lap bar 4 is placed at one side on the core groove 6 of the magnetic head and at the other on the vertically position adjustable V-groove 7. The parallelism in the vertical directions of the lap bar 4 with respect to the track faces 1 is adjusted by adjusting the vertical positions of the V-groove 7 with a micrometer 8. The lap bar is so designed as to finish the side  faces of the track faces 1 evenly and highly accurately with an axial vibrator 12,  thus correction working may be readily accomplished.

Abstract: PURPOSE: To improve quality of semiconductor substrate, by successively forming the first and second single crystal magnesia spinel layers on a single crystal silicon substrate in controlled growth temperature and feed gas amount and then growing a single crystal semiconductor layer.  
     CONSTITUTION: A magnesia spinel layer 21 which is the first layer having good crystallizability is formed on a single crystal silicon substrate 1 by controlling growth temperature of a spinel layer to prescribed optimum temperature range.

Title: Magnetic head
Inventor: AKIYASU HIROSHI
IPC: G11B5/127
Filed: 1986-07-07
Abstract: PURPOSE:To reduce the slide noise level by interposing an oxide magnetic thin film to a junction boundary between a single crystal ferrite and a polycrystal ferrite so as to suppress the length of the single crystal ferrite to a prescribed value accurately. CONSTITUTION:The single crystal ferrite 1 constituting a magnetic gap (g) at the contact face of a magnetic recording medium and the polycrystal ferrite 2 occupying most parts of the magnetic circuit at the back gap side of the magnetic head are bonded and integrated via an oxide magnetic thin film 3. The oxide magnetic thin film 3 has very minute and well-arranged crystal grains and shows discontinuous grain growth by heating. Thus, in applying a hot pressing processing at a temperature lower than the temperature where the oxide magnetic thin film 3 is subjected to crystal grain growth, no diffusion layer is formed between the single crystal ferrite 1 and the polycrystal ferrite 2, the waving at the boundary is eliminated and the length L of the single crystal ferrite 1 is formed accurately to a prescribed value. Thus, the slide noise level is remarkably decreased.

Title: Magnetic metal powder
Inventor: TAMAI KIMINORI
IPC: B22F1/02
Filed: 1984-07-31
Abstract: PURPOSE:To obtain the magnetic powder having the oxidational stability for a long period of time even in the atmosphere of high temperature and high humidity, especially suitable for a magnetic recording medium, by a method wherein an isocyanate compound is adhered to the surface of magnetic metal powder. CONSTITUTION:An isocyanate compound is adhered to the surface of magnetic metal powder. Any well known magnetic metal powder can be used as the magnetic recording medium for metal magnetic powder. An arbitrary isocyanate compound such as mono or polyisocyanate compound can be used as an isocyanate compound. The isocyanate compound has no effect of oxidational stability when its quantity is too small, and the effect of oxidational stability is saturated, if its quantity is too much. On the other hand, when the quantity of isocyanate compound is increased, magnetic characteristics are deteriorated, and this tendency is promoted when an excessive quantity of isocyanate compound is adhered. Accordingly, the rate of isocyanate used is to be 0.1-10%, desirably within the range of 0.5-5%.

CONSTITUTION:After having grown a thermal oxide film on an Si substrate 1, an SiN film is formed where an SiO2 film 2 and an SiO film are etched by using a photo mask 14 which comprises a main pattern mask 2 having a broader width W1 in a longitudinal direction and an auxiliary pattern mask 3 having a narrower width W2 than the width W1, thereby forming an element isolation region and an active area. Then, the element isolation region is thermally oxidized so that the thermal oxide film may be grown and then the SiN film is formed, thereby forming a side wall which comprises an SiO2 film 4a and an SiN film 5a by carrying out anisotropic etching. Then, the exposed surface of the Si substrate is thermally oxidized, thereby forming an element isolation film 7. This construction makes it possible to inhibit a bird's-beak penetration or a pattern shift.

Title: Image reader, standard white board for shading correction, and shading correction circuit
Inventor: OHASHI KAZUHITO
IPC: H04N1/401
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive image reader by vapor-depositing aluminum on one face of a white polyester film piece and setting it to be a standard white board for shading correction. SOLUTION: Aluminum is vapor-deposited on the upper face of the film piece 42 which is cut and it is inserted between a metallic base board 44 and a glass board 46. Namely, the aluminum vapor deposition face of the film piece 42 is stuck to the metallic base board 44 and the glass board 46 is bonded to an opposite face. Then, aluminum is vapor-deposited on one face of the whole polyester film and the opposite face is set to be a read face. In the polyester film, the white degree of a material itself is considerably stable and it can be generated as the film of the same density for a wide area. The effect of a member positioned at the backside can be prevented by vapor-depositing aluminum.  Thus, the standard white board for shading correction, which is considerably inexpensive, has less color nonuniformity and has high quality, can be obtained and the image reader can also inexpensively be manufactured.

Abstract: PURPOSE: To prevent the breakage caused by the deflection of a mold and to avoid the development of a stress concn. position at the time of assembly by pressing a shell so as to sealingly engage with a lower portion and arranging a spring means resisted to the outer force loaded to the mold in a vacuum chamber. CONSTITUTION: The air spring 46 presses a plunger 42 downward, and when the mold 6 positions in the opening part 18 of a box 22, the shell part 8 is elastically pressed to the lower mold portion 10. A Shrader valve 48 is arranged on the air spring 46 and if necessary, the valve 48 changes the pressure in the spring 46 and the pressure force is loaded so that the upper shell portion 8 is sealingly engaged with the lower mold portion 10. Then, if necessary, at the time of giving the casting vacuum, the breakage caused by the deflection of the mold 6 inward can be prevented. Force applied with the plunger 42 does not become so larger as to break by exerting the excess force to a fixed part 28, or to push out the mold 6 from the opening part 18 of the box 22 or to break the sealness formed thereat.
