Title: Magnetic disk
Inventor: HOSHINO SHIGEKI
IPC: G11B5/82
Filed: 1988-03-25
Abstract: PURPOSE:To provide excellent wear resistant to the above disk and to decrease the friction on the surface by forming plural grooves on the surface of a protective film formed of diamond-like carbon. CONSTITUTION:A thin Si film 14 is formed on an Al substrate 11 on which an NiP plating layer 12 and a magnetic film 13 are successively formed in order to enhance the adhesiveness between the magnetic layer and the diamond- like carbon film. The diamond-like carbon film 15 is then formed on this film 14. The grooves 16 are thereafter formed vertically and horizontally on the film 15. The protective film is formed on the rear face as well by the same process as the above-mentioned process. The friction on the surface is thereby decreased while the magnetic film 13 is protected by the excellent characteristics of the diamond-like carbon film.

Title: Defective sector replacing system for disk
IPC: G06F3/06
Filed: 1991-04-02
Abstract: PURPOSE:To shorten a retrieving time at the time of operation and to effectively utilize a substitution area by changing a defective leading or final sector when the leading or final sector in a substitution area is defective, and substituting the succeeding sector for the defective leading or final sector. CONSTITUTION:The leading sector and the final sector in a substitution area are set up to the 100th and 199th sectors, and when a defective sector exists on the end part of an idle substitution area, the defective sector is removed from the area. Namely, when the 100th sector is defective, the leading sector in the idle substitution area is replaced by the 101th sector, and when the 199th sector is defective, the final sector is replaced by the 198th sector. Thereby, useless information is not used only by disusing the 100th or 199th sector. When a defective sector is not in existence in the end part of the area, e.g. when the 102th sector is defective, the final sector in the idle substitution area is used for substitution, and whether the final sector, i.e., the 198th sector, has been used for substitution or not is judged. When the 198th sector is not used for substitution yet, the 198th sector is used for substitution for the 102th defective sector.

Title: Production of steel sheet excellent in deep drawability
Inventor: KAWABE HIDENAO
IPC: C22C38/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To improve deep drawability by applying finish rolling and heat treatment to a steel stock of prescribed composition under respectively prescribed conditions. SOLUTION: This stock contains, other than usually contained C, Si, Mn, P, S, Al, N, and B, either or both of 0.005-0.2wt.% Ti and 0.005-0.20wt.% Nb in order to improve deep drawability in particular. This steel stock is treated based on the obtained knowledge, that is, finish rolling is carried out under nonlubricating or slight-degree lubricating condition at a temp. in the range between the Ar3 transformation point and 500 deg.C so that total draft becomes 50-95% and the draft at the final pass and the deformation resistance at the final pass are regulated to <=50% and >=150MPa, respectively, and then, the resultant steel sheet is self-annealed or is heated to 700-950 deg.C soaking temp. to undergo recrystallization treatment. By this method, the necessity of high- degree lubricating rolling to improve the r-value of rolled stock can be obviated, and the steel sheet excellent in deep drawability can be produced.

Title: Electrohydraulic steering apparatus
Inventor: OOHASHI AKIRA
IPC: B63H25/24
Filed: 1978-06-12
Abstract: PURPOSE: To improve the mainpulating property of an electro-hydraulic steering apparatus, by decreasing the ratio of the steering angle to the rotation angle of a steering wheel when the wheel is in or near the neutral position and increasing the ratio when the steering wheel is distant from the neutral position.  
     CONSTITUTION: When a setting potentiometer 2 directly coupled to the steering wheel 1 is rotated by the wheel, a difference is made between the output voltages of the potentiometer and a feedback potentiometer 5, which is rotated depending on the steering angle. The difference is amplified by an amplifier 6 to shift a solenoid valve 7 to displace a rudder 3 to a desired angle. A non-linear potentiometer is used as the feedback potentiometer 5. When the steering wheel 1 is in or near the neutral position, the ratio of the steering angle to the rotation angle of the steering wheel 1 is decreased. When the steering wheel is distant from the neutral position, the ratio is increased.

Abstract: PURPOSE:To easily and efficiently test a D/A converter in a short time by outputting a digital signal over all the conversion range areas to the D/A converter to be tested while successively increasing or decreasing the digital signal based on a switching signal from a switching period detecting means. CONSTITUTION:When a reference voltage is increased or decreased with the passage of time and is made more or less than the analog output voltage of the D/A converter to be tested, a switching period detecting means 2 outputs the switching signal. Based on this switching signal, a digital signal generating means 3 outputs the digital signal over all the conversion range areas to the D/A converter 1 to be tested while increasing or decreasing the digital signal. Therefore, the analog output voltage of the D/A converter 1 is increased or decreased corresponding to the digital signal. When the reference voltage is increased or decreased, similarly based on the switching signal from the switching period detecting means 2, the digital signal to be outputted form the digital signal generating means 3 to the D/A converter 1 to be tested is outputted while being successively increased or decreased. Thus, the D/A converter 1 to be tested can be easily tested in a short time.

Title: Magnetic recording medium
Inventor: OGUCHI TOSHIHIKO
IPC: C09D167/00
Filed: 1989-03-23
Abstract: PURPOSE:To alleviate surface roughness and to improve recording/reproducing characteristics in a short wavelength region by coating a substrate with specific hexagonal Ba-ferrite ferromagnetic powder and a binder resin. CONSTITUTION:The substrate is coated with hexagonal ferrite ferromagnetic powder having 0.01 to 0.1mum particle size and coercive force Hc of 600 to 2,000Oe with a binder resin of 1,000 to 6,000mol.wt. having metal sulfonate. This low mol.wt. resin can intrude into the spaces between the accumulated ferrite particles. Once the resin introduces between the particles, the metal sulfonate firmly adheres to the surface of the powder particles. Thereby, dispersibility of the powder is increased and the layer has small surface roughness when oriented.

Filed: 1988-03-24
Abstract: PURPOSE:To prevent the generation of delamination and cracks, by specifying the mixing ratio of mixed material layers of insulator material and dielectric material to be interposed between an insulator layer and a dielectric layer. CONSTITUTION:Two kinds of mixed material layers 7a, 7b are formed. The mixing ratio of insulating material and dielectric material is in the range 95:5-5:95wt.%.
