IPC: G11B5/84
Filed: 1993-03-09
Abstract: PURPOSE:To evaluate a magnetic coating material in real time by providing an apparatus for production of magnetic recording media of a coating type with a measuring instrument for calculating the measured value of electromagnetic conversion characteristics by outputting/ inputting signals to and from magnetic heads. CONSTITUTION:A cord-like body 2 of the device for evaluating the electromagnetic conversion characteristics of the magnetic coating material for magnetic recording media. is pulled up at a prescribed speed by a take-up device 6. The magnetic coating material deposited on this body is adjusted to a prescribed thickness by a device 3 for adjusting the film thickness. While the magnetic coating material passes an orienting magnet 11, the magnetic particles of the coating material are unified in a specific direction and the coating material is dried, by which a magnetic coating film is formed. The cord-like body 2 is then admitted into a pipe 5 to be disposed with the magnetic head and while the body passes a passage 8, the signals are recorded by the magnetic head 9 for recording. The signals are reproduced by the magnetic head 10 for reproducing. The measuring instrument 13 outputs the signals for recording while changing the recording currents or recording frequencies to the magnetic head 9 and calculates the measured value of the electromagnetic conversion characteristics by being inputted with the signals reproduced by the magnetic head 10.

Title: Selective coating method
Inventor: YADA TOSHIO
IPC: B05D5/06
Filed: 1979-04-19
Abstract: PURPOSE: The method of coating only the groove portions which comprises forming an alkali-soluble material layer on a substrate at the portions other than the grooves of the groove patterns thereon and forming the coating film which is insoluble or hard to dissolve in alkalis on this substrate then dipping the same in an alkali solution and which permits simple and large-volume treatment even if the coating film is thick.  
     CONSTITUTION: Alkali-soluble resist patterns 2 are formed on a substrate 1 made of stainless steel and are etched to form groove 3 patterns. Thence, when alkali-soluble paint or ink is roller-coated, an alkali-soluble layer 6 is deposited only on the substrate noncoated portions 5. The paint insoluble or hard to dissolve in alkalis composed primarily of acrylic acid resin or the like is coated over the entire surface of said substrate, whereby a coating film 4 is formed. Thence, when the substrate is dipped in an aqueous NaOH solution, the resist patterns 2 and layer 6 dissolve and at the same time the coating film 4 thereon is stripped. In this case, even if the coating film 4 is thick, the alkali solution makes good infiltration action. In this way, only the coating films 4 of the groove 3 portions remain.

Abstract: PURPOSE:To obtain the titled compound in high yield, by reacting m-xylene with sulfuric acid, by prescribing the sulfuric acid concentration in a mother liquor in a specific range, crystallizing m-xylene-4-sulfonic acid. CONSTITUTION:In reacting m-xylene with sulfuric acid to prepare m-xylene-4- sulfonic acid, crystallizing it from a solution of a reaction product, the crystallization is carried out in a condition of 50-70wt% (the rest is water) sulfuric acid concentration in the mother liquor. The solubility of m-xylene-4-sulfonic acid in an aqueous solution of sulfuric acid varies greatly with the concentration of sulfuric acid, shows the minimum value particularly in approximately 60wt% sulfuric acid concentration, and the difference in the solubility is small in a range of 50-70wt%. m-Xylene-4-sulfonic acid is crystallized as a dihydrate, so that the sulfuric acid concentration of the solution of the reaction product rises in proportion to the amount of crystallization. Since the solubility rises abruptly in >=80wt% sulfuric acid concentation, the solution is maintaind in the range. The reaction of m-xylene and sulfuric acid is carried out at 70-80 deg.C, and the crystallization temperature is preferably 20-40 deg.C.
