Title: Production of magnetic head
Inventor: KAMIHIRA AKIRA
IPC: G11B5/235
Filed: 1977-10-11
Abstract: PURPOSE: To form narrow gaps readily with good accuracy and enable abrasion resistance of heads to be made by forming a non-ferromagnetic metal layer which becomes an operating gap through electroplating and binding the same with other core material and amorphous alloy layer.  
     CONSTITUTION: An amorphous alloy layer 3 is electroplated on the gap face 2 of a head chip 1 and its neighborhood and is then polished in approximately parallel with the face 2, whereby a gap forming face 4 is obtained. Next, a non-ferromagnetic metal (alloy) layer 5 is electroplated to the thickness corresponding to an operating gap 6 on the face 4. Over this is electroplated an amorphous alloy layer 7 of the same composition as that of the layer 3, and a groove 10 is formed in opposition to the gap face 9 of the opposing head chip 8. Next, the chip 8 is fitted in the groove 10, and the amorphous alloy layer 11 is electroplated in continuation to the layer 7, whereby an integrated amorphous alloy layer 12 is obtained. Next, the layers 3, 5, 12 are polished and a magnetic head 14 having a tape running face 13 is produced. a suitable binding agent is filled in a back gap 15

Filed: 1986-05-29
Abstract: PURPOSE:To reduce the number of interconnection signals and to improve a transmitting characteristic and miscellaneous denaturation resistance by connecting both the systems of optical swithes which is made to possess one input to plural branch outputs and one selection output in plural inputs. CONSTITUTION:As an optical switch 9 branches the input of a branch input terminal 9a to branch outputs terminals 9b and 9c and outputs them, it selects either input of selection input terminals 9d and 9e and outputs it from a selection terminal 9f. The switch 9 is inserted in both A and B systems of optical transmission lines and one of the selection input terminals corresponding to one of the branch output terminals of A and B systems of the switch 9 is connected mutually through a loop back optical path 11. Thus the transmission and the miscellaneous denaturation resistance of the loop back between both A and B systems can be improved and also both received data and receiving timing need not be switched and connected, so that the number of interconnection signals can be reduced.

Title: Dewatering method for steel strip
Inventor: TAKEMOTO MASAKANE
IPC: C23G1/00
Filed: 1981-08-06
Abstract: PURPOSE:To dewater the surfaces of a steel strip effectively in the stage of removing hot water from the steel strip after treatment by specifying the temp. of the hot water and adding a suitable amt. of a specific fluorinated surfactant to the hot water thereby making the surfaces of the steel strip water repellent with the surfactant. CONSTITUTION:After the surfaces of a steel strip 11 are treated with a surface treating soln. 1, the soln. 1 is squeezed with rubber rolls 2, and the strip is washed in a hot water bath 9 and is then dewatered. Here, the hot water in the bath 9 is maintained at 40-90 deg.C, and a fluorinated surfactant consisting essentially of polyfluoroalkyl groups is added thereto at 0.01-2.0%. As said temp. is higher, the rate of adsorption of the surfactant molecules on the surfaces of the steel strip to be given water repellency is higher. The surfactant is required to be contained above the lower limit in order to provide a satisfactory dewatering effect in a short contact time, but in excess of the upper limit, the hydrophilic groups orient without orientation of the perfluoroalkyl groups on the surfaces of the steel strip, thus degrading the dewatering effect. According to this method, the soln. is removed satisfactorily simply by blowing air or hot water with the device 10.
